| [{"Instruction": "Provide affordable transportation options in St. Louis", "Response": "Whether you're traveling around St. Louis on vacation, visiting the area on business or live in the metro area, there are several ways to get around St. Louis on the cheap. The city's bus, train or van metro system are among the cheapest ways to get around. Another good note is that if you're visiting the dowtown STL area during the week, there are often \"City Guide\" personnel roaming (either on bike or foot), that will assist with any directions.\n\n## Plan your trip\n\n1. Use St. Louis area maps to make getting around easier and cheaper. The St. Louis Convention and Visitor's Commission offers several downtown, metro and area maps that can help you plan your visit.\n2. Use the trip planner on the St. Louis Metro Transit website to plan the easiest and least costly routes around the city. The planner can help you choose between taking a taxi, the MetroBus or MetroLink train.\n\n\n## Ride the metrolink\n\n1. Purchase MetroLink tickets at vending machines in MetroLink stations. You can buy tickets or weekly and monthly passes with cash or a credit card. You can also purchase passes at the downtown St. Louis MetroRide store or online at the St. Louis Metro website. Buy either a 1-hour, 2-hour or 1-day pass for the MetroLink system. Two-hour and day passes also give you access to the MetroBus system while traveling in St. Louis. Passes start at just $2 for adults.\n2. Choose which MetroLink line you need to take to reach your destination. The MetroLink operates a Red Line between the Lambert Airport in Missouri and the Shiloh-Scott Station in Illinois. The Blue Line operates between the Shrewsbury-Lansdowne I-44 stop in Missouri and a station in Fairview Heights, Illinois.\n\n\n## Ride the metrobus\n\n1. Plan a MetroBus route. You can travel from Illinois to Missouri via MetroBus routes. The system's stops include many of the city's major attractions, like the civic center, Laclede's Landing and Busch Stadium. Use the MetroBus schedule to help find the best route to your destination before purchasing your tickets. Some routes may be quickest and less expensive if you combine a ride on the MetroBus with the MetroLink.\n2. Pay your MetroBus fare with exact change as you board, or purchase a MetroBus pass or tickets ahead of time at the MetroRide store in downtown St. Louis or online. If you'll be using both MetroLink and MetroBus, consider buying a combo fare pass at the store to save money.\n\n\n## Use the metro call-a-ride service\n\n1. Call for door-to-door transportation service in many areas of the city through the Metro Call-a-ride program. The service is available as a link to the MetroBus or MetroLink services, or from other designated locations. Call-a-Ride rates start at $13.\n2. Consider using the Metro Call-A-Ride if you or anyone in your party has a disability. The ride program is available for those who qualify for the Americans With Disabilities Act at a reduced rate starting at $4.\n3. Call 314-652-3617 or toll free 888-652-3617, up to a week in advance to reserve curb-side service from Metro Call-A-Ride. You can make reservations the day you travel, but Call-a-Ride cannot guarantee you space.\n"}, 4] | |
| [{"Instruction": "Explain the differences between presidential semi-presidential and parliamentary democracies", "Response": "Democracies come in various shapes and sizes. One way of classifying democracies is into presidential, semi-presidential, and parliamentary democracies. The key differences lie in the checks and balances between the executive branch (the government) and the legislative branch (the legislature):\n\n* In a presidential democracy, the government is not responsible to the legislature, i.e. it cannot be removed by a vote of no-confidence. For example, in the United States, the president is elected separately from Congress, and cannot be removed by congress during their term, apart from extreme circumstances (impeachment and conviction).\n\n* In a semi-presidential democracy, the head of state is elected independently of the legislature, and is not responsible to the legislature, but the government is. For example, France is a semi-presidential democracy, where the president is elected directly by the citizens, but the government and prime minister are voted in by the parliament.\n\n* In a parliamentary democracy, the government is responsible to the legislature, aligning the executive and legislative branches. Many parliamentary democracies elect their head of state via the legislature, while others, such as the United Kingdom, have a hereditary head of state."}, 5] | |

Assuming a single-threaded application (as most are), your entire application will stop responding, rather than just delaying an operation as you probably intended. Note that it may be fine to use Sleep in pure console application as there are no \"events\" to handle or on separate thread (also ```Task.Delay``` is better option).\nIn addition to timers and ```Sleep``` you can use ```Task.Delay``` which is asynchronous version of ```Sleep``` that does not block thread from processing events (if used properly - don't turn it into infinite sleep with ```.Wait()```). \n``` public async void ClickHandler(...)\n {\n // whatever you need to do before delay goes here\n await Task.Delay(2000);\n // whatever you need to do after delay.\n }\n```\nThe same ```await Task.Delay(2000)``` can be used in a ```Main``` method of a console application if you use C# 7.1 (Async main on MSDN blogs).\nNote: delaying operation with ```Sleep``` has benefit of avoiding race conditions that comes from potentially starting multiple operations with timers/```Delay```. Unfortunately freezing UI-based application is not acceptable so you need to think about what will happen if you start multiple delays (i.e. if it is triggered by a button click) - consider disabling such button, or canceling the timer/task or making sure delayed operation can be done multiple times safely."}, 5] | |

| [{"Instruction": "Explain how to solve the Shakespeare puzzle in Silent Hill 3 for all difficulty levels.", "Response": "Silent Hill 3 is the third installment in the Silent Hill video game series. It is considered to be a survival horror video game in which your character must solve different puzzles and psychological challenges in order to advance. The Shakespeare puzzle can be found during the Shopping Center stage. It’s inside a bookstore called My Bestsellers.\n\n## Solve the puzzle on easy mode\n\n1. Pick up the Shakespeare books that have fallen on the ground. In this difficulty, there will only be 2 books on the ground: Anthology 1 and Anthology 3.\n2. Examine the bookshelf. You’ll be allowed to place the books you found on the floor in the empty slots.\n3. Click on Anthology 1 and place it on the first slot of the bookshelf.\n4. Click on Anthology 3 and place it on the third slot on the bookshelf. A code will appear after placing the two books correctly.\n5. Use the code on the door at the back side of the bookstore. In this puzzle, you only need to arrange the books in the proper order: (from left to right) Anthology 1, Anthology 2, Anthology 3, Anthology 4, and then Anthology 5.\n\n\n## Solve the puzzle on normal mode\n\n1. Read the note on the door. It will read “Fair is foul, and foul is fair. Put these books out of order.”\n2. Pick up all the books on the floor. There will be 5 books in normal mode.\n3. Examine the bookshelf. You’ll be allowed to place the books on the empty space on the shelf. Put the books in randomly; order doesn’t matter as this puzzle is generated randomly.\n4. Take a good look at the books. You’ll see there are black markings on it; this is the code you need.\n5. Arrange the books until you get the correct order. It won’t be too hard as the numbers are written quite obviously. Try to make out the numbers written on the spine of the books and keep moving them until you get it right.\n\n\n## Solve the puzzle on hard mode\n\n1. Know the title of each anthology book. In order to find the title of the book, you’ll need to open your inventory and choose to examine the book. Anthology 1 is Romeo and Juliet\n\t* Anthology 2 is King Lear\n\t* Anthology 3 is Macbeth\n\t* Anthology 4 is Hamlet\n\t* Anthology 5 is Othello\n2. Decipher the first stanza of the clue. This stanza mentions “The first words at thy left hand.”\n\t* This is an instruction for solving the puzzle; meaning you’ll need to arrange the books from left to right.\n3. Place Anthology 4 on the first spot on the left side of the bookshelf. The first stanza mentions “false lunacy” and “incomprehensible words,” which is a reference to the plot of Hamlet.\n4. Place Anthology 1 on the second spot of the bookshelf. The second stanza is the easiest to decipher “playing at death” and “nameless lover” refers to the last part of Romeo and Juliet.\n5. Place Anthology 5 on the third spot on the bookshelf. This stanza is a reference to Othello, referring to the innocence of Desdemona and the lies of Iago.\n6. Place Anthology 2 on the fourth spot on the bookshelf. This stanza refers to the story of King Lear, where his daughter Cordelia refuses to speak about how much she loves her father as opposed to the false flattery of her sisters.\n7. Place Anthology 3 on the last spot on the bookshelf. And with all 5 books on the bookshelf you would have the correct code.\n8. Decipher the last clue. 41523 is not the pass code; on the sixth stanza, you will be instructed to more. “41523—One vengeful man spilled blood for two” (Hamlet). This means you will have to double Hamlet, which is Anthology 4. Now our code is 81523. “81523—Two youths shed tears for 3”; this refers to Romeo and Juliet, so you must replace 1 with 3. Our code now is 83523. Finally, “3 witches disappear” (reference to Macbeth), which is Anthology 3. You’ll have to remove it from the code. The final pass code is 8352.\n9. Enter the code on the door to unlock it. The puzzle in hard mode does not randomize; the code will always be 8352 on any Silent Hill 3 game.\n"}, 5] | |
| [{"Instruction": "Explain why hot water can freeze faster than cold water.", "Response": "In certain settings, cold water freezers slower than hot water. This is called the Mpemba effect:\n\nHot water can in fact freeze faster than cold water for a wide range of experimental conditions. This phenomenon is extremely counterintuitive, and surprising even to most scientists, but it is in fact real. It has been seen and studied in numerous experiments. While this phenomenon has been known for centuries, and was described by Aristotle, Bacon, and Descartes, it was not introduced to the modern scientific community until 1969, by a Tanzanian high school student named Mpemba.\n\nHere are some suggested reasons:\n\n1. Evaporation — As the initially warmer water cools to the initial temperature of the initially cooler water, it may lose significant amounts of water to evaporation. The reduced mass will make it easier for the water to cool and freeze. Then the initially warmer water can freeze before the initially cooler water, but will make less ice.\n2. Dissolved Gasses — Hot water can hold less dissolved gas than cold water, and large amounts of gas escape upon boiling. So the initially warmer water may have less dissolved gas than the initially cooler water."}, 4] | |

| [{"Instruction": "Explain the origin and meaning of \"white elephant\" in English.", "Response": "In fact, the English expression for a burdensome gift is literally white elephant:\n\n> a thing that is useless and no longer needed, although it may have cost a lot of money [OALD]\n\nSo-called white elephants, or albino elephants, are found in many parts of South and Southeast Asia. In Buddhist countries they may be venerated as Queen Maya, mother of the Buddha, was said to have been visited in a dream by a white elephant holding a white lotus flower, and Siddharth Gautama entered his mother's womb in the form a white elephant. The white elephant is also associated with traits like mental strength and purity.\nIt became a royal symbol in Siam (Thailand); the king continues to keep white elephants. The story emerged that if a courtier displeased him, the king would make him a gift of a white elephant. The courtier could hardly decline a royal gift, and could hardly afford not to maintain a sacred animal, and could not put it to productive use, and so would be ruined by the cost of upkeep.\nThe earliest example of its use is from a 1721 essay in London Journal:\n\n In short, Honour and Victory are generally no more than white Elephants; and for white Elephants the most destructive Wars have been often made.\n\nA 2011 paper by Ross Bullen entitled “This Alarming Generosity”: White Elephants and the Logic of the Gift, in American Literature, covers the popularization of the term in the mid-19th century, presents an alternative account, that the story is a piece of orientalism and the white elephant rose as a literary trope."}, 4] | |
| [{"Instruction": "How to manage and prevent hernias effectively?", "Response": "## Reduce and manage pain\n\n1. Take over-the-counter pain meds to help relieve your discomfort. Aspirin and ibuprofen may work well to alleviate some pain and swelling. Follow the recommended dosage on the bottle and don’t exceed the daily limit. If you find your pain doesn’t get better or if you keep taking more and more medication, it may be time to call your doctor. If you take a blood thinner, always check with your doctor before using pain medication. They may want you to take something different so it doesn’t interfere with the blood thinner. Types of Hernias: Almost all hernias will eventually need to be treated through surgery, especially if they’re bulging or causing you a lot of pain. Some of the more common types of hernias include:\n\t* Inguinal hernia: This type of hernia is in the groin area; it most often affects men, though women can experience it, too. Femoral hernia: This hernia is located around the top of your inner thigh, caused by part of your intestines pushing through your groin. These are most common among older women. Hiatal hernia: This hernia appears on your abdomen as part of your stomach protrudes into your chest cavity. Umbilical hernia: This occurs when tissue pushes through your abdomen near your belly button. It can affect both infants and adults.\n2. Avoid heartburn-causing foods and large meals if you have a hiatal hernia. This is the one type of hernia that sometimes doesn’t need surgery, especially if its symptoms can be managed through diet and over-the-counter antacids. If your symptoms increase over time, though, surgery may become the best solution.Enjoy multiple small meals throughout the day instead of 3 larger ones. This will put less pressure on your stomach so you’re more comfortable all day long. Avoid caffeine, chocolate, garlic, tomatoes, and other fatty or fried foods that can cause heartburn. Don’t lay down after you eat for several hours.\n3. Relieve discomfort from an inguinal hernia with a truss. A truss is a supportive undergarment that helps keep your hernia in place—it’s a temporary solution to help relieve pain until you can have surgery. You can buy a truss online, but it’s best to visit your doctor so they can make sure it’s properly fitted. Most inguinal hernias do need surgery to be repaired, but if your hernia is really small and not causing you pain, your doctor may be okay with waiting and keeping an eye on it. Surgery may sound scary, but these procedures usually take less than an hour and should quickly help relieve your pain.\n4. Eat a fiber-rich diet to make bowel movements softer and easier to pass. Straining your muscles can aggravate your hernia, and constipation can make things worse. Add lots of fruits and vegetables to your daily diet, and consider taking a fiber supplement to help things move smoothly.Oatmeal, nuts, beans, popcorn, chia seeds, and whole grains are also great high-fiber food choices.\n5. Lose weight to take pressure off of your abdomen. This can be helpful for all types of hernias; the less weight you’re carrying around, the less strain your muscles will be under. Try modifying your diet by eating leaner proteins and more fruits and vegetables, and try adding in some gentle exercise every day to lose weight.Hernias can be really uncomfortable and it may be hard for you to imagine exercising. Try going for short 15-minute walks when you can, or go to the pool and slowly swim laps. Be gentle on yourself, though, so you don’t aggravate the hernia more.\n\n\n## Prevent further damage\n\n1. Avoid lifting bulky or heavy objects that may strain your muscles. Instead of bending over at the waist to pick up heavy items, bend your knees so you’re squatting. Bring the object close to you and then straighten your legs and stand up. Keep the heavy object at chest level and try not to twist and turn too much.For heavy items you can’t lift yourself, consider using a dolly. You wedge the bottom of the dolly under the item, then use your weight to pull on the dolly’s handle to lift the object. From there, you can wheel it wherever it needs to go.\n2. Relax while going to the bathroom so you don’t strain your groin area. This is a little counterintuitive, but try to not strain when you have a bowel movement. Take your time and don’t push too hard; instead, let your body slowly work things out—it may take longer than usual, but it’s gentler on your body and can prevent further damage.A high-fiber diet can help prevent hernias as well as manage discomfort if you already have one. Putting your feet up on a short stool may also make those muscles relax and help you go to the bathroom more easily. Add a hot cup of coffee to your morning routine. The heat and caffeine can help things get moving.\n3. Strengthen your abdominal muscles to prevent additional hernias. Weak muscles make it easier for your internal organs to break through your abdominal walls. The key to strengthening your core is to do so gently—too much pressure or exertion could actually cause a hernia, so start slow and stop any exercises that cause you pain. Try doing 3 sets of 10 mini crunches every day. Lay on your back with your knees bent and put your hands behind your head. Use your ab muscles to bring your shoulders up off the ground 3 to 4 inches (76 to 102 mm) before carefully lowering yourself back to the ground. Workout at the pool for low-resistance strength training. The support of the water will make it easier for you to exercise without having to strain your abdominals as much. Start slow if you’re new to swimming or doing water exercises, and enjoy your time in the water! Take a beginner’s yoga class to gently stretch and tone your core.\n4. Quit smoking to improve lung health and eliminate excessive coughing. There are lots of reasons to quit smoking, and doing so can also help prevent hernias. Chronic coughing strains your muscles in both your abdomen and groin, so start curbing your smoking habit or quit cold turkey. It can be extremely hard to stop smoking. If you’re having a hard time, talk to your doctor. They may be able to provide you with some kind of aid to help make the transition easier.\n\n\n## Seek medical care\n\n1. See your doctor for an official diagnosis before treating yourself. You will likely recognize the signs and symptoms of a hernia on your own, especially if it’s large. However, it’s easy to misdiagnose yourself, so see your doctor to make sure what you have is a hernia. Your doctor will make a proper diagnosis so you can be sure you’re getting the right treatment.Your doctor will do a physical examination to check for a hernia. They’ll look at the area and may press into it with their hands. In some cases, your doctor may do imaging tests to view the hernia.\n2. Talk with your child’s pediatrician if they develop an umbilical hernia. For infants and children under 5, always check with your pediatrician to see what they recommend. Many times, an infant’s hernia will close all on its own over time, but if it hasn’t gone away by the time your child is 5 years old, they may need a small procedure to have it fixed.Umbilical hernias are common with infants, and they usually don’t cause your child any pain or discomfort.\n3. Let your doctor know if you have a hernia while you’re pregnant. Because of the extra strain on your body, hernias are fairly common among pregnant women. If you suspect you have a hernia, talk to your doctor so they can check it out. Your doctor will most likely want to wait until after birth and recovery before treating the hernia if you need surgery, but you and your baby should be safe in the meantime.As much as you can, avoid heavy lifting and make sure to eat a high-fiber diet to prevent constipation.\n4. Visit your doctor as soon as possible if your hernia looks dark red or purple. This can be a sign that your hernia is strangulated. When this happens, your hernia is cutting off the blood flow to part of your intestine and requires medical treatment. Go to the doctor to make sure you’re okay because you may need emergency treatment.Try your best to not worry or panic—your doctor will be able to fix your hernia.\n5. Seek emergency care if you have pain, nausea, vomiting, or blocked bowels. Sometimes a hernia can block off part of your intestines. This means your bowel movements can get caught behind the hernia, causing pain, nausea, vomiting, and bloating. You will likely not be able to pass gas or have a bowel movement. See your doctor or go to the emergency room if this happens because you likely need medical treatment.This is a treatable condition, though it can be really scary at the moment. As soon as you suspect a problem, get medical attention so you can get back to normal as soon as possible.\n6. Have a surgical procedure done to correct your hernia and prevent future ones. These procedures are generally pretty quick and you should get to go home that same day. The surgeon will usually make a small incision near the hernia and push it back into place. From there, they will sew and reinforce the tear so that the hernia will be less likely to protrude again.Make sure to follow all recovery instructions after your surgery. You’ll need to take it easy and avoid heavy lifting for a while, and you’ll probably also have pain medication to take.\n"}, 4] | |
| [{"Instruction": "Tell me different ways to cook corn on the cob and kernels", "Response": "There are many different yet simple ways to cook corn. Corn on the cob can be boiled, microwaved, grilled, steamed, or baked, while loose kernel corn is usually boiled, steamed, or microwaved. Keep reading to learn more about your preferred cooking method.\n\n## Boiling corn on the cob[1]\n x\n research source\n\n1. Boil a large stockpot of water. Meanwhile, prepare the corn cobs by removing the husks and silks. The exact amount of water you need will vary depending on how large each ear of corn is. Make sure that you use enough water to completely cover the ears of corn once they are submerged. Note that you can add up to 1 tsp (5 mL) salt to the water if desired, but it is not needed. To remove the husks, snap off the stem of the corn with your hands. Pull the stem over the length of the corn to peel off the husks still attached to it. Remove the remaining husks by peeling them off with your fingers. Rinse the husk-free corn cobs under running water. Rub your hands over the corn to loose and free as many of the silky threads you spot clinging to the corn.\n2. Transfer the corn to the boiling water. Cover the pot and let it return to boiling. Use tongs to dunk the corn into the water. Avoid using your hands to transfer the corn since doing so may result in burns. If the boiling slows or stops after you place the corn in the stockpot, allow the water to reach a boiling point again before timing the cooking process.\n3. Cook for 3 to 8 minutes. The corn should be \"tender-crisp\" when done. \"Tender-crisp\" means that the corn is soft enough to press, but not mushy. The precise amount of cooking time will vary based on the type of corn and how mature it is. Fresh corn and sweet corn usually cook fastest.\n4. Remove and serve. Transfer the ears of corn to a layer of clean paper towels and let drain for 30 to 60 seconds before serving. The corn will be hot, so you may want to wait a few minutes before biting into it. Corn is usually served with a drizzle of butter.\n\n\n## Microwaving corn on the cob[2]\n x\n research source\n\n1. Place an ear of corn in a microwave-safe dish. You will need to cook the corn one ear at a time, but the instructions are the same for each ear. Do not remove the husk. The corn will cook better in the microwave if left in the husk during the cooking process.\n2. Microwave the corn for 5 minutes. The microwave should be set on high power or full power. Let stand in the microwave for 1 to 2 minutes to avoid burning yourself with the steam.\n3. Transfer the corn to a cutting board. Cut of the stem end using a sharp kitchen knife. Use oven mitts or a towel when removing the corn from the microwave. As you cut, you should also remove the first row of kernels. Make sure to cut through the husk completely.\n4. Slip the corn out of its husk and serve. Use oven mitts or a towel to grab hold of the corn from the uncut top end. Gently shake the ear, allowing the corn to slip free. The ear of corn should slip out of the husk easily. Usually, even the silks will remain left behind inside the husks. You can serve the corn with butter and salt, or however you prefer it.\n\n\n## Grilling corn on the cob\n\n1. Preheat your grill to medium-high heat. Meanwhile, remove the husks and silks from your ears of corn. If using a gas grill, set all the burners to medium-high heat and allow the grill to preheat for 5 to 10 minutes. If using a charcoal grill, allow a thick layer of coals to burn until white ash begins to form over the surface. Husk the corn by snapping off the stem and pulling it over the length of the corn, thereby removing the husk attached to the stem. Peel away the rest of the husk with your fingers. Rinse the ears under running water to remove most of the loose silks.\n2. Brush the corn with olive oil. Use a basting brush to apply a thin coat of olive oil to the surface of each ear of corn. Use no more than 1 Tbsp (15 mL) olive oil per ear. You could also use melted butter instead of olive oil.\n3. Transfer the corn to the grill. Cook for 6 to 10 minutes. Turn the corn occasionally to ensure even cooking and prevent burning. The corn is done once the majority of the kernels begin to brown lightly. It will also be charred in some spots, especially near the smaller kernels.\n4. Serve as desired. Remove the corn from the grill and transfer each ear to a serving platter. Let cool until you can handle it comfortably with your bare hands. Butter and salt are frequently served with corn, but if you used butter on the corn before grilling it, you may find that you do not need to add more.\n\n\n## Steaming corn on the cob[3]\n x\n research source\n\n1. Boil water in the bottom portion of a steamer. Husk and de-silk the ears of corn as you wait. If you do not have an actual steamer, you can use a large stockpot and perforated metal colander instead. Make sure that the metal colander can rest on the lip of the stockpot before attempting to use it, however. The basket portion of the colander should not dip below the halfway point of the stockpot. Snap off the stem of the corn and pull it over the length of the ear, removing the attached husk. Peel the rest of the husk away with your fingers. Rinse the corn under cool running water, scrubbing it gently with your hands. This should remove the majority of the silks.\n2. Transfer the corn to the steaming basket. Cook for 8 to 12 minutes. Use tongs to transfer the corn into the steaming basket. Using your hands could result in burns. The exact cooking time will vary depending on how mature the corn is. Fresher corn cooks quicker than older corn. The corn is done once the kernels feel tender but not mushy.\n3. Serve warm. Remove the corn from the steamer with your tongs and let rest for a minute or two before enjoying. Season with butter and salt, if desired.\n\n\n## Baking corn on the cob[4]\n x\n research source\n\n1. Preheat the oven to 425 degrees Fahrenheit (220 degrees Celsius). Remove the husks and silks from each ear of corn as the oven preheats. To remove the husk from an ear of corn, snap off the stem using your hands. Pull the broken stem down over the ear, stripping away any husk attached to it. Peel the rest of the exposed husk away with your fingers. Rinse each corn cob under running water, scrubbing gently with your hands to remove any visible silks. Pat dry with paper towels.\n2. Season the ears with butter. You can also add a little salt and pepper, if desired. Use plenty of butter. Spread at least 1 to 2 Tbsp of melted butter over each ear.\n3. Wrap each ear in aluminum foil. Each ear must be completely wrapped inside its own sheet of aluminum foil. If you are worried about butter leaking out from the aluminum foil, place a flat baking sheet or jelly-roll pan beneath the wrapped ears of corn to catch any dripping butter.\n4. Bake the corn for 20 to 30 minutes. Most ears of corn will only take 20 minutes to cook, but larger ears may need as many as 30 minutes. Place the corn on the middle rack of your oven to ensure the most even cooking.\n5. Remove and serve. Let the cooked ears of corn rest for 2 to 5 minutes before carefully removing the aluminum foil. Serve once they are cool enough to touch.\n\n\n## Boiling corn kernels\n\n1. Boil water in a medium saucepan. Meanwhile, measure out your frozen whole corn kernels. You can add up to 1 tsp (5 mL) of salt to the boiling water, if desired, but the salt is not necessary. The corn does not need to be thawed prior to use. You could also use canned corn kernels instead of frozen corn. Note that the amount of time needed to boil canned corn is significantly less than the amount of time needed to boil frozen corn. Additionally, canned corn should be drained before you add it to the boiling water.\n2. Add the corn to the boiling water. If the boiling decreases or stops, let the water come up to a boil again. After it returns to a rolling boil, reduce the heat to medium-low.\n3. Cover and cook. Frozen whole kernels of corn should simmer for 5 to 10 minutes. Drain once finished. Canned corn should only boil for 1 to 3 minutes. Once finished, the corn should be hot and tender but not mushy.\n4. Serve as desired. Do not refreeze corn kernels after cooking them. If desired, you can mix the cooked corn kernels with butter, salt, and black pepper. You can also use other seasonings, like parsley, according to your own tastes.\n\n\n## Steaming corn kernels\n\n1. Simmer water in a steamer. Fill the lower part of a steamer with water and heat, on the stove, over medium heat until the water steams and starts to simmer. Do not boil the water. Do not fill the steamer high enough for water to slip up through the holes of the steamer basket. If you do not have a steamer, you could use a stockpot and a metal colander with fine holes. Make sure that the colander fits over the lip of the stockpot without falling in.\n2. Add frozen corn kernels into the steamer basket. Spread the kernels out into a single layer. Canned corn kernels can also be used, but they will finish cooking in a much shorter amount of time. They may also be soggier once finished. You do not need to thaw frozen corn kernels before use.\n3. Cook for 9 to 10 minutes. Allow the corn to steam for 9 to 10 minutes without covering it. Drain once finished. Canned kernels will only need to steam for 3 or 4 minutes.\n4. Serve. Steamed corn can be served with butter and salt as well as other seasonings.\n\n\n## Microwaving corn kernels\n\n1. Place corn kernels in a microwave-safe dish. Spread frozen corn kernels into an even layer in the dish. Canned corn kernels can also be used, but there are some differences in the cooking method and length. Frozen corn does not need to be thawed prior to cooking.\n2. Add 2 to 4 Tbsp (30 to 60 mL) of water. Stir the water into the corn to disperse it throughout. Note that this step is only needed if using frozen corn kernels. You do not need to add water if using canned corn, but you should not drain the canned corn before use.\n3. Cover the dish with plastic wrap. Use a fork to poke a few holes into the plastic wrap, providing ventilation. Only use plastic wrap that is safe to use in the microwave. If the dish has a cover, you could use that instead of the plastic wrap. Make sure that the cover is placed on the dish loosely so that the corn is still ventilated.\n4. Microwave for 4 to 5 minutes. If using canned corn, only microwave the dish for 1 to 2 minutes. The exact length of time varies depending on how much wattage your microwave has. A lower-powered microwave will need longer time, while a higher-powered microwave will need less time. If you hear popping sounds as the corn cooks, stop the microwave early.\n5. Drain and serve. Drain the cooking liquid from the corn and season as desired with butter, salt, and pepper.\n\n\n## Charcoal grilled corn on the cob\n\n1. Cut the tip of each ear of corn off. Soak the corn in the husks in a sink or a big pot in 4 to 6 inches (10.2 to 15.2 cm) of tap water for about an hour.\n2. While they're soaking, prepare your outdoor charcoal grill. Add enough coals for an hour of cooking.\n3. Place the corn still in the husks on the grill. Cook for about an hour, turning occasionally, allowing the husks to char.\n4. Remove the husks.\n5. Add butter, salt and pepper to taste. Serve immediately.\n"}, 4] | |
| [{"Instruction": "Explain the historical evolution and current state of RISC and CISC architectures.", "Response": "There is a general historical trend.\nIn the olden days, memories were small, and so programs were perforce small. Also, compilers were not very smart, and many programs were written in assembler, so it was considered a good thing to be able to write a program using few instructions. Instruction pipelines were simple, and processors grabbed one instruction at a time to execute it. The machinery inside the processor was quite complex anyway; decoding instructions was not felt to be much of a burden. \nIn the 1970s, CPU and compiler designers realized that having such complex instructions was not so helpful after all. It was difficult to design processors in which those instructions were really efficient, and it was difficult to design compilers that really took advantage of these instructions. Chip area and compiler complexity was better spent on more generic pursuits such as more general-purpose registers. The Wikipedia article on RISC explains this in more detail.\nMIPS is the ultimate RISC architecture, which is why it's taught so often.\nThe x86 family is a bit different. It was originally a CISC architecture meant for systems with very small memory (no room for large instructions), and has undergone many successive versions. Today's x86 instruction set is not only complicated because it's CISC, but because it's really a 8088 with a 80386 with a Pentium possibly with an x86_64 processor.\nIn today's world, RISC and CISC are no longer the black-and-white distinction they might have been once. Most CPU architectures have evolved to different shades of grey.\nOn the RISC side, some modern MIPS variants have added multiplication and division instructions, with a non-uniform encoding. ARM processors have become more complex: many of them have a 16-bit instruction set called Thumb in addition to the “original” 32-bit instructions, not to mention Jazelle to execute JVM instructions on the CPU. Modern ARM processors also have SIMD instructions for multimedia applications: some complex instructions do pay after all.\nOn the CISC side, all recent processors are to some extent RISC inside. They have microcode to define all these complex macro instructions. The sheer complexity of the processor makes the design of each model take several years, even with a RISC design, what with the large number of components, with pipelining and predictive execution and whatnot.\nSo why do the fastest processors remain CISC outside? Part of it, in the case of the x86 (32-bit and 64-bit) family, is historical compatibility. But that's not the whole of it. In the early 2000s, Intel tried pushing the Itanium architecture. Itanium is an extreme case of complex instructions (not really CISC, though: its design has been dubbed EPIC). It even does away with the old-fashioned idea of executing instructions in sequence: all instructions are executed in parallel until the next barrier. One of the reasons Itanium didn't take is that nobody, whether at Intel or elsewhere, could write a decent compiler for it. Now a good old mostly-sequential processor like x86_64, that's something we understand."}, 3] | |

| [{"Instruction": "Explain the significance of the Septuagint compared to Masoretic texts before and after 1947.", "Response": "Before 1947, a good case could be made that the Septuagint represented a more ancient tradition than the Masoretic versions of the Tanakh. Since the Septuagint was produced before 132 BCE (and probably in the 3rd century BCE) and the earliest known Masoretic manuscripts date to the 10th century CE, the Greek translation might have fossilized an early rendering of the Scriptures while the Hebrew continued to be copied and potentially altered. To further support the primacy of the Septuagint, the early Christian and Hellenistic Jewish texts, tended to use that translation rather go back to Hebrew sources.\nAn interesting counter-argument arises from the observation that during the 600 years from Jerome's translation into Latin (the Vulgate) to the earliest Masoretic manuscripts, the Hebrew seems to have been faithfully copied. That suggests that Jewish scribes were exceptionally careful to duplicate their scriptures.\nAfter 1947, the evidence changed. According to Wikipedia:\n\n [Most] of the Qumran fragments can be classified as being closer to the Masoretic text than to any other text group that has survived. According to Lawrence Schiffman, 60% can be classed as being of proto-Masoretic type, and a further 20% Qumran style with bases in proto-Masoretic texts, compared to 5% proto-Samaritan type, 5% Septuagintal type, and 10% non-aligned. Joseph Fitzmyer noted the following regarding the findings at Qumran Cave 4 in particular: \"Such ancient recensional forms of Old Testament books bear witness to an unsuspected textual diversity that once existed; these texts merit far greater study and attention than they have been accorded till now. Thus, the differences in the Septuagint are no longer considered the result of a poor or tendentious attempt to translate the Hebrew into the Greek; rather they testify to a different pre-Christian form of the Hebrew text\".\n\nAnother another article describes the meaning of the categories in detail.\nA few caveats are in order:\n\n* Surveying the Qumran about religious texts seems something akin to surveying a hippie commune about political issues—you're likely to experience some bias. If we could obtain a similar collection from Jerusalem, we'd likely find more agreement and likely the side of MT. Given the diversity in non-Scriptural texts, 60% seems quite solid support.\n* While it's unlikely, there exists a chronological possibility the scrolls associated with the Septuagint-aligned Hebrew were influenced by the Greek. (Any references one way or the other would be appreciated.) \n\nWhat remains therefore is a window into the community of Alexandrian Jews that produced the translation. For those who are interested in the development of Jewish belief, that can be extremely useful. N. T. Wright's book, The Resurrection of the Son of God, shows that the LXX translators chose to interpret key texts from Daniel and Ezekiel about the resurrection as literal rather than metaphorical. He argues from this that belief in bodily resurrection was more common in Jesus' day than other scholars assert."}, 4] | |

| [{"Instruction": "Organize holiday plans for sleep, budget, shopping, and cooking efficiently.", "Response": "## Personal holiday organization\n\n1. Plan for sleep. One of the dangers of the holiday season is that you schedule too much and don't budget enough time for sleep and exercise. These 2 practices can cut your stress level in half and make it easier to stay on task during your holiday rush. It is common to reduce your exercise time slightly during the holidays, but try to get about 30 minutes of mid-intensity cardiovascular exercise 5 times per week. Don't not cut down on your sleep; aim for 8 hours per night. Moderate your alcohol intake. Although it may seem like a sedative, it can actually prevent you from getting deep sleep. Stop after a few drinks to avoid losing your energy the next day.\n2. Set a budget 2 months before the holidays. Take into account how much you can afford and then split the money between cards, postage stamps, gifts, decorations, clothing, food and even a party. Plan an overage of 10 percent in your budget. This means all of your needs should add up to 90 percent of the money you have for the holidays.\n3. Sit down with your family 6 weeks before the holiday and ask for help. If you love control, this may be hard to do; however, it will take a load off your shoulders and make everyone feel like the holidays don't come together magically.\n4. Discuss the possibility of doing a low-gift giving Christmas or a charity project with your family. If your budget is tight, then giving 1 present or buying 1 big present for the whole family might be better. Studies have also shown that charity projects can help your emotional health during stressful times.\n5. Book travel plans 3 or more months before the holidays. Ticket prices tend to go up right before the holidays. Make sure you have lower travel costs and less stress associated with travel if you and your children or parents have their plans figured out in advance.\n6. Use a calendar that everyone can see, online or in the house. Place all commitments, deadlines, family nights and tasks on it so that everyone can refer back to it over the month of December.\n\n\n## Holiday shop organization\n\n1. Schedule shopping intelligently rather than in blocks. The following are good tips that make holiday shopping more effective and quick:\n\t* Buy things throughout the year, whenever you see something that is ideal for someone. You provide more thoughtful gifts if they are catered to the person, rather than bought frantically the month before. Store your gifts in 1 place in your house and come back to your gift hiding place 6 weeks before Chanukah or Christmas. Take a few hours off work during mid-week once the holiday sales start. You will miss the rush and have a more calm shopping experience. Shop in small spurts online. Getting online for hours can be a waste of time. Keep a list in your purse of things you are looking for, and add to it. Wait until you have 2 or 3 things you know you want to search for and do your power shopping. Open 3 browser tabs and compare prices on Amazon, Overtock.com and a Google Shopping page. Don't be afraid to give gift certificates. Many stores, massage parlors, movie theaters and more provide gift certificates. Think of something that your friends or family will find truly valuable over a product you are unsure they will like.\n2. Set up a wrapping station on a table in late November or early December. Wrap gifts as soon as you bring them home. This will remove the chance that children will find their gifts and it will allow you to get both shopping and wrapping done at a slow and steady pace.\n3. Aim to finish your shopping and wrapping by December 15th. Schedule your time accordingly, so that you can enjoy the holidays and be ready for any last-minute changes.\n\n\n## Holiday cook organization\n\n1. Clean your kitchen from top to bottom before attempting holiday baking or cooking. Try to do this in late November or early December. Rearrange things that overnight guests will need, such as coffee and cereal, in an easy to reach cupboard and create a baking cupboard.\n2. Stock up on baking supplies early in the season. Buy flour, sugar and spices at warehouse stores so that you don't have to make late night runs to the supermarket. Buy some pre-made pie crusts and cookies to keep around in case you don't have time to do everything from scratch.\n3. Bake throughout the holiday season. Clear out your freezer, and then create a cooking to do list that allows you to make and freeze items every week. For example, bake 1 sweet, such as cookies or candy, and prepare 1 side dish in preparation. Cover and label the dishes very well before you stack them on a freezer. For example, \"Sweet Potatoes. Thaw and bake at 350 for 30 minutes.\"\n4. Plan a holiday potluck party instead of baking all of the food. This is a great way to lower your budget and have fun. Allow people to bring desserts, side dishes or relish to family dinners as well; they understand your kitchen is very full.\n"}, 4] | |

| [{"Instruction": "Give tips on what to wear for a gym workout.", "Response": "When you go to the gym, it's important to wear clothes that are breathable and flexible. It's good to look good – but remember that fitness and safety are your foremost concerns. Ill-fitting clothing can cause itchy skin, rashes, or more serious injuries. Also, be mindful that your clothes may shift when you're working out. Wear clothing that will facilitate a solid workout.\n\n## Dress for women\n\n1. Choose a lightweight t-shirt or sweatshirt. Wear a breathable material like cotton or polyester. When you work out, you'll grow hot and sweaty, so you want to make sure that your clothing doesn't trap the heat. If possible, choose a top that is specifically designed for wicking sweat. Consider wearing a tank top or sports bra for a more breathable—if more revealing—outfit. If you have large breasts, then a sports bra may be essential for a comfortable gym experience. No matter your size, a bit of extra support never hurts.\n2. Pick your bottoms. Wear something flexible, with an elastic waistband: gym shorts, sweatpants, track pants, or yoga pants. You should be able to perform a full range of leg workouts while you're wearing the bottoms. The bottoms that you wear also depend on the effect that you're going for: tight and skin-showing clothing can help you show off, and baggier, more flowing garments might help you blend in. Short shorts may afford you the most flexibility, but they can also show a lot of skin. If you feel shy in shorts: wear sweats or yoga pants. If you wear shorts, inspect yourself from all angles in a mirror before you go to the gym. Keep in mind that people may be able to see up the leg of your shorts when you're using certain equipment, like the leg press.\n3. Bring appropriate footwear. The shoes you wear will depend upon the sort of exercises that you're doing. If you plan to do any cardio, then bring shoes that will offer plenty of protection for your feet and legs. Keep in mind that a lot of gyms don't allow open-toed shoes. If you'll be running on a treadmill, then make sure to bring running shoes. If you will be using an elliptical or exercise bike, then your footwear doesn't matter so much – just wear something comfortable that you can stand in. If you'll be training weights, make sure to wear something with ample ankle and arch support. Running shoes are always a good choice.\n\n\n## Dress for men\n\n1. Wear shorts or sweats. Make sure that your bottoms give you a full range of motion. Be conscious of how much you will sweat during your workout, and think about how hot you're going to get. Try not to wear shorts that extend more than an inch below your knees – especially if they are loose around the legs. The lower your shorts, the shorter your range of motion. If you decide to wear shorts, be aware that other people may be able to see up the leg of your shorts when you're using machines like the leg press.\n2. Take a breathable, flexible shirt. A cotton t-shirt or tank will suffice. Alternately, choose a breathable, sweat-wicking polyester shirt. Pick something that will absorb sweat and that won't restrict your range of motion. A tank will show off your arms, and a t-shirt can be a slightly more modest choice. Decide what you're going for.\n3. Choose appropriate footwear. The shoes you wear will depend upon the sort of exercises that you're doing. If you plan to do any cardio, then bring shoes that will offer plenty of protection for your feet and legs. If you'll be running on a treadmill, then make sure to bring running shoes. If you will be using an elliptical or exercise bike, then your footwear doesn't matter so much – just wear something comfortable that you can stand in. If you'll be training weights, make sure to wear something with ample ankle and arch support. Running shoes are always a good choice.\n\n\n## General advice\n\n1. Wear lightweight, breathable socks. Cotton socks are generally a good choice. Make sure that the socks are neither too tight nor too loose! Wear high socks or low socks, to your taste. Short socks will give your legs more space to breathe, but high socks can be useful for wicking away sweat. Tight socks can constrict your legs and slow your blood circulation. On the other hand, socks that are too loose might distract you by sliding down your legs.\n2. Carry a towel. As you move about the gym, use a soft, clean towel to wipe your sweat away. You don't want to leave your sweat on the seat of a machine! Most gyms provide clean towels for members to use during their workouts. Do not share a towel with anyone, or else you risk sharing germs! Clean up any sweat that you do leave on a machine. Use a small, clean towel to wipe down the seat, the bars, and any other part that your sweat has touched. Your sweat carries bacteria that could infect someone else if left to dry on the machine!\n3. Wash your clothes after the gym. Even your own sweat, when left to dry on fabric, can breed nasty bacteria and then infect you. Odor-making bacteria tend to grow better on polyester than on cotton – but you should wash all gym clothes regardless.\n"}, 4] | |

| [{"Instruction": "Create DIY Halloween decorations using household items.", "Response": "There are thousands of Halloween decorations you could go out to the store and buy, but often they look generic and plastic-y, don't they? Why not make your own? Using household items, you can make your own ghosts, bats, spiders, and pumpkins! Here's how.\n\n## Ghostly spirit jugs\n\n1. Clean several plastic milk jugs. You don't need to cut them out or in any way modify them -- they just need to be clean. Each one will be one ghost -- how many milk jugs do you need?\n2. Draw a face on the jugs. You can either use a black permanent marker, felt, or any material you have lying around the house. The permanent marker will be the easiest to make a detailed face with. While you do this, only work on the side without the handles and leave the caps on the jugs. The air forced to stay inside by the caps will make it easier to work with, keeping it sturdy. You don't have to go Martha Stewart on this project. Just a circle for a mouth and circles for eyes (leave a little white for the pupils) can be cute, too.\n3. Cut a small hole in the back of the jug. Use a craft knife to cut a hole the size of a half dollar or a bit bigger than a pound coin. Place the hole about 2/3 of the way up the jug. This won't be seen. If it's not perfect, don't worry about it. Just don't leave any sharp edges!\n4. Stuff the jug with Christmas or fairy lights. You can either use a whole string for one jug, or thread several jugs with a single string. Arrange the jugs together, plug in the cord, and voila! These little buggers work great lining a walk or a patio or table edge. They dim the lighting just enough to glow in a very Halloween-y feel!\n\n\n## Flapping bats\n\n1. Cut a body, two wings, and the head of a bat (with ears!) out of a piece of paper. You can find a template online or you can freehand it. Make the body a little on the chubby side so you have room to attach the wings without drawing away from its size.\n2. Trace your template onto black craft foam. Cut out the foam to match the template. This project looks best if you have about 6 or so bats. They need friends!\n3. Punch several holes into the bat to join the pieces together. Punch two holes on each wing, close to where the wings would attach to the body. Leave a little space around all sides so the holes don't turn into rips. Also punch a hole at the bottom of the body, to attach a string later (around where a tail would be). The holes just have to be big enough to put a metal brad through. This is how the wings will flap.\n4. Align the holes on the body and the wings together and fasten with a brad. Since there are two holes on each side, use the one that's closest to the wing tip. Place a paper fastener or a brad through the hole and secure loosely (it's best to use a black fastener or color your gold brad).\n5. Thread a string through the empty holes and tie in a loop. That's why you pierced two holes in each bat initially! You'll probably want at least 10 inches (25 cm) of string (or dental floss), so the string is easy to grab. This is how you'll manipulate the wings. When you hang your bat up, you can just give the string a tug and away he'll go!\n6. Attach a ribbon and red sequin eyes. Thread the ribbon through the bottom hole to hang the bat upside down from your wall or ledge. Tie it in a loop and knot. Then, make red eyes with sequins. Googly eyes work, too!\n\n\n## Flowerpot pumpkins\n\n1. Purchase a few terra cotta pots. Having a variety of sizes will give you a pumpkin family! Make sure they're clean if you had them laying around the house. You want them very orange to simulate pumpkins.\n2. Cut the parts of a face out of yellow craft paper. If you don't have craft paper, use scrapbook paper, card, or wrapping paper. Anything that's bendy and colorful will work. Make arched evil eyebrows, a handlebar mustache, surprised eyes, or any detail that you'd like your pumpkin pots to have. The simpler your face, the more it will look like a jack-o-lantern. Give it a toothy grin, a triangular nose, and triangular eyes to make it look more pumpkin-esque.\n3. Brush the surface of the pot with outdoor modge-podge. You only need a layer on the side you'll place the face for right now. Use a sponge brush or paint brush for best results. A thin, but even layer is ideal.\n4. Apply the pieces of the face to the upside down pot. Press them firmly into place. Then, apply a thin layer of the sticky stuff all over the pot, effectively weather-proofing it.\n5. Insert a stick into the end for a stem. When we say stick, we mean stick. Go outside under a tree and find a stick to fit through the bottom of your terra cotta pot. And there it is -- a pumpkin that won't rot in a week's time!\n\n\n## Giant spooky spiders\n\n1. Cut off the spout of an empty, clean milk jug. Just below the lid is what you don't want. Use a craft knife to make this easy -- scissors will be difficult to work with. Make sure your milk jug is clean! If there's still a milky residue it may end up smelling.\n2. Cover the jug with black tape. This will form the body of your spider. Go as tightly around the handle as you can; but don't worry -- if it's still discernible, that's fine.\n3. Get 4 6-foot (2 m) black foam pipe insulation tubes that are 1/2 inch (1.25 cm) in diameter. These will be the legs. Tape each one in the center along the handle of the jug. Then, tape the tubes along the sides of the jug too, to make it look as if the legs are going along the body. The tubes will bend into place.\n4. Cut a slit at a joint in the legs. If you cut a slit in the tube, it will bend at your cut. If you hold it in the bend, you can tape it to stay permanently bent. This will form the joints in your spiders legs. A 1\" (2.5 cm) triangle cut is good -- the tube won't unexpectedly break off. Just hold it at its bending point and wrap tape around the newly-formed joint.\n5. Use two halves of a plastic Easter egg for eyes. They'll bulge out and be adequately creepy -- especially if you cut a slit of black tape for pupils. If you don't have an egg lying around, puff balls (or anything circular, really) work as well. Just attach them to the jug with more tape or glue.\n\n\n## Adorable hanging ghosts\n\n1. Create your ghost form with two small paper cups. Turn the first one upside down, then place the second one on top of that. To make it stable, tape or glue the bottoms together. You won't actually be using the cups as part of the ghost -- it's just used for sizing in the initial stages. So if you don't want to fuss with tape, don't worry about it!\n2. Inflate a small balloon and put it in the top cup. But not too much! If it's too big it won't fit in the cup. Make it so it fills out the cup, like a round poof of whipped cream tops a mug of hot chocolate.\n3. Soak pieces of cheesecloth in fabric stiffener. You'll want to work with pieces that are about 8 inches (20 cm) square. Grab a bowl and fill it with fabric stiffener, soaking each piece thoroughly. About 10 seconds per piece will do the job nicely.\n4. Immediately drape over the balloon. After you've soaked a piece, drape it over the balloon and move onto the next piece. Center the pieces, evenly draped over the balloon, but not perfectly uniform. Once you've finished with all your pieces, let it dry for about ten minutes. It will then harden and take shape.\n5. Pop the balloon! This will require a needle or other pointy object since you can't go smashing your creation on the floor (well, you could, if you get really frustrated -- but that'd defeat the purpose). After you do so, you should be left with a free-floating white ghost-like creation. Isn't Halloween the best?\n6. Remove from the cup and rough up the edges. The ends should look tattered, as if they're wafting in some sort of unregisterable-to-humans breeze. Just bending them with your fingers should do the trick.\n7. Attach felt eyes and fishing line to hang. Little tiny black dots for eyes are all these little guys need to be cute and not at all ominous. Black sequins or beads can work, too. As for the fishing line, just thread it through the cheesecloth, loop, and tie in a knot! Hang your new buddies from lights, shelves, windows, or the ceiling.\n\n\n## Eyes in a bush\n\n1. Get an empty toilet paper roll, and a glowstick. You can easily find both at a dollar store.\n2. Cut out two football shaped eye holes. Place them about two to three inches (5 to 7.5cm) apart.\n3. Put the glowsticks in the center of the toilet paper roll. Do not cause them to glow until they need to be used as a decoration on the night of Halloween.\n4. Put the roll(s) in your bushes/trees. When you cause the glowsticks tot work, you will have scary eyes in a bush!\n\n\n## Paper bag ghosts\n\n1. Obtain rubber bands and a white paper bag.\n2. Draw a ghost face on the paper bag.\n3. Put the rubber band around the middle of the bag.\n4. Decorate. Add the face of a ghost and any other designs.\n5. Hang up from the ceiling, on branches, etc.\n\n\n## Scary halloween candy bowl\n\n1. Get a fake hand, a bowl, glue, and candy. The glue must be non-toxic as food is going to come into contact with it.\n2. Glue the fake hand onto the bottom of the bowl.\n3. Let the glue dry for about two to three hours.\n4. Fill the bowl with candy.\n5. Set the bowl out for the trick or treaters.\n"}, 5] | |
| [{"Instruction": "Explain how to use TikTok for business promotion.", "Response": "For most people, TikTok is a fun way to kill time and share zany videos with friends. In the right hands, however, it can also be a useful promotional tool. Taking advantage of the app’s unique format can help business owners get more eyes on their products and services, especially if they’re aimed at a younger target audience.\n\n## Establish a presence\n\n1. Create an official TikTok account for your business. When you open the app for the first time, you’ll be given the option to sign up using your phone number, email address, or a third-party platform like Facebook. Once you’ve successfully created an account, tap the person-shaped icon in the lower righthand corner and hit “Edit Profile” to access your user settings. There, you can change your name, write out a custom bio, and upload a profile picture or video.You’ll find TikTok listed near the top of the “Most Downloaded” section of your preferred app store.\n2. Build a profile that represents your business well. Start by choosing a distinctive profile picture that will make your account instantly identifiable. A logo, mascot, or photo of one of your products will work best in most cases. Then, draft a short bio that explains who you are, what you do, and why your followers should be interested.Be sure to include a link to your website or online store in your bio. That way, users will be able to find out more about your business just by visiting your profile.Tip: Asking yourself questions like, “Who is my target audience?”, “What am I hoping to show my followers?”, and, “How does this app fit in with my other marketing strategies?” while you’re tinkering with your profile can help you zero in a more effective presentation.\n3. Familiarize yourself with the app’s basic format. While it offers a host of different features, TikTok is primarily a video sharing platform that lets users upload video clips up to 15 seconds in length. This rapid-fire setup forces content creators to find imaginative ways to capture their viewers’ attention and make a statement fast.Users also have the option of setting their videos to popular songs and sound clips in order to make playful lip syncing videos, produce mini music videos, or just add a little extra style. If you have a longer video that you want to show, it’s also possible to connect multiple segments that will play continuously for up to 60 seconds.\n4. Take advantage of the app’s built-in editing features when posting videos. When you’re ready to get creating, tap the “+” button in the bottom center of the screen. This will pull up the in-app camera, allowing you to shoot a video that’s anywhere between 15 and 60 seconds in length. When you’re done, you’ll have the option to trim your video, add stylish transitions, write custom captions, and layer on filters and other special effects.One of TikTok’s most beloved features is the ability to add backing music and sound clips. Tap on the “Music” icon in your editing dashboard to browse an absolutely massive library of hit songs from all eras. You can also hit the “Upload” icon to the right of the red “Record” button to upload a video that you shot on your device earlier. This feature can be handy in those situations where you want to prepare a new post but don’t have a lot of time to play around on the app.\n\n\n## Produce effective content\n\n1. Focus on putting together videos that are fun and engaging. TikTok is an unconventional app, so it’s no place for conventional advertising. Spend some time coming up with ideas for posts that you think will pique your audience’s interest, make them laugh, or encourage them to try out your product or service for themselves. The ultimate goal is for your brand to stick in their memory.Viral dance videos are all the rage on TikTok, so if you’ve got some sweet moves up your sleeve, now’s the time to show the world. Use this opportunity to get creative and think outside the advertising box—crack jokes, incorporate chart-topping songs, or work in clever pop culture references that will help you gain traction with your audience. Anything goes!\n2. Make sure your content comes across as genuine. While there’s a virtually unlimited number of ways to express your business’s “personality” on TikTok, it’s crucial that your content have a casual, down-to-earth feel to it. If it seems forced or insincere, your audience won’t buy it—and that’s exactly what you’re trying to get them to do.Old-fashioned ads rarely get a second look these days. But if you can highlight the exciting, adventurous, or playful aspects of your business in a way that makes users feel like they’re a part of something, it’s sure to get them talking. The kind of people who value the app’s open-ended, creative format are notoriously hard to sway using traditional marketing strategies, and tend to appreciate businesses that seem relatable and take more of a down-to-earth approach.Tip: Forget about polished, overly formal sales pitches. TikTok culture is all about fun, spontaneity, and accessibility, with a strong \"DIY\" aesthetic.\n3. Create short product demonstrations. Make videos of yourself or your team members actually using the items you’re advertising. This is a good chance to show your viewers just what your products can do, or to highlight any key features or intended uses it might have.A video of someone sipping an ice cold soft drink on the beach surrounded by friends, for instance, will be much more likely to make an impression on viewers than one showing someone drinking the same beverage alone in their kitchen. Remember, you only have 15 seconds, so you’ll need to either edit together a montage of quick cuts or skip to the most impressive part of your demonstration in order to get your message across.\n4. Start a viral hashtag challenge. Come up with a unique way to get your audience to engage with a particular product or service, give it a catchy hashtag, and offer to share or repost select submissions from users who add the hashtag to their posts. Not only will this give them a chance to gain some exposure by being featured on your account, it will also ensure that your hashtag is spread far and wide.Imagine that you run a footwear company called Swiftz. You might challenge TikTok users to post videos of themselves wearing your shoes for their favorite activities with the hashtag, “#SwiftzTakesMe.”\n5. Encourage users to interact with your posts. Whenever you put up a new post, include a call-to-action to motivate viewers to like, comment, and share. Doing so will let them establish a kind of dialogue with your company, increasing its visibility in the process. On an app like TikTok, greater visibility means greater discoverability, which in turn means more customers.Prompts like, “Tell us which feature of our new jeans you like best in the comments!” or, “What other uses have you discovered for our infinitely-customizable storage cubes?” give your audience a chance to take a more active role in your branding efforts. Another way to expand your reach is to ask viewers to post videos of themselves using your product or explaining what they like about it for a shot at a repost, similar to hashtag challenge.\n\n\n## Buy ad space on tiktok\n\n1. Publish in-feed native content. In-feed native ads are video ads that pop up periodically between regular user videos. When you post one of these ads, it will appear as a full-screen, skippable video, similar to branded stories on Instagram. This is the most straightforward way to advertise on TikTok, and probably the one that promises the most visibility overall.If you’re interested in making use of TikTok’s ad service, you’ll need to work with one of the company’s marketing reps, who will provide you with all the info you need regarding pricing, structure, and targeting. Once your ad has been posted, you can track its outreach by reviewing a number of different metrics, including clicks, views, play duration, and interactions like comments and shares.Tip: While building your ad, you’ll have the option of including links to your website, online store, or app, as well as hashtags that users can click on to see similar content.\n2. Stage a brand takeover. Brand takeovers are large-scale social media marketing campaigns that allow brands to “take over” an app for a single day. What this means is that your business’s branding elements will be displayed on the app’s home screen for 24 hours. During that time, you can also use the app’s creative features to mass-distribute targeted content containing clickable hashtags and embedded links to your website or product pages.For more information on pricing and availability, get in touch with a TikTok marketing rep by visiting the Advertising section of the company’s website. There are also “Top View” takeover packages available that transition directly into 15-second in-feed video ads from the home screen.\n3. Pay for promoted hashtags. Promoted hashtags essentially accomplish the same thing as homegrown hashtag challenges. The main difference is that instead of relying on your audience to spread word of your challenge, TikTok will market it for you through targeted posts. Needless to say, it has the potential to find its way around to a lot more users this way.Having TikTok share your business’s hashtags can seriously increase your web traffic, but it definitely isn’t cheap. By some estimates, purchasing a promoted hashtag could run you as much as $150,000!\n4. Apply for your own branded lenses. Lenses are editing features that enable TikTok users to enhance their images and videos by adding special effects, much like the filters on Snapchat and Instagram. Users who try out your lenses will be sending a subtle message to their followers to check out your business. The more people you can get using your lenses, the more name recognition you stand to earn yourself.If you opt to go this route, you’ll work closely with TikTok’s marketing experts to develop lenses based on some aspect of your business’s branding. Ideally, your lenses should offer users a cool new effect or look to play around with, not just plaster your name or logo everywhere. Don’t forget that your objective is to actually get people to use it.\n5. Work with well-known influencers to grow your audience faster. One of the best ways to generate a buzz when you’re just starting out is to collaborate with users who already have a dedicated following. If you come across a particular TikTok star who you think might make a good promotional partner, reach out to them via direct message and see if they would be interested in joining forces.Keep in mind that the most influential figures on social media are usually professionals, so you should be prepared to provide compensation if you want to hitch a ride on their reputation. With the right spokesperson, you could see an explosion in your follower numbers and outside web traffic literally overnight.\n"}, 4] | |
| [{"Instruction": "How to make warm and cold water wax?", "Response": "## Make warm water wax\n\n1. Heat water in a double broiler. Pour in about 1 ½ cups (354.8 ml) of water in the bottom of a double broiler. Heat on medium heat until the water is hot and steaming. You do not need to boil the water, you just need it to be hot enough to melt the beeswax through steaming. If you don't have a double broiler, you can also simply heat water in a pot on the stove, then put an equal sized pot on top of it to create the effect of a double broiler.\n2. Place the beeswax and coconut oil in the top of the double broiler. Once the water has heated and is steaming, place 1 cup (240 ml) of beeswax and ¼ cup (60 ml) of coconut oil in the top pan of the double broiler. Place the top of the double broiler on top of the bottom pan.\n3. Melt the ingredients, stirring constantly. Once you place the beeswax and coconut oil over the bottom of the broiler, they should begin to melt. As they melt, stir the ingredients constantly so that they don't get stuck to the sides of the pan.\n4. Add in essential oils. If you want your wax to be fragrant, add a few of drops of essential oils when the wax and coconut oil have melted and mixed together. Popular oils to use are lavender, peppermint, lemon or rosemary. If you prefer the subtle scent of the coconut oil, don't add any essential oil.\n\n\n## Make cold water wax\n\n1. Find a healthy conifer. Cold-water wax differs from warm-water wax because it requires the addition of tree resin. To extract tree resin, first find a conifer tree that generally looks healthy, with relatively smooth, tight bark and without many dead branches or limbs. Conifer trees are trees that grow conifers, the cone-like growths that grow on tree branches. Examples of conifers are pine, spruce, maple and cedar trees. If you don't want to extract tree resin yourself, you can find it on Ebay or other online sites.\n2. Create a flat, cleared area on the face of the tree. Once you have found a suitable tree, use a machete or a hatchet to cut downward on the bark about 3 feet from the ground. Make a rectangle that is about 10 inches long and 6 inches wide. Try to cut cleanly so that you cut out a flat area about 1 inch deep into the tree.\n3. Place a bucket under the tree. Place a bucket against the tree directly underneath where you made the rectangular indent. Use a flat piece of metal or another smooth material to make a ramp that leads from the cleared rectangle into the bucket. The ramp will catch the resin as it comes out of the tree and lead it into the bucket. Therefore, it's important that the ramp is flush against the tree and leads directly into the bucket.\n4. Cut V-shaped notches into the cleared rectangle. After you set up the bucket, use the hatchet or machete to hack into the cleared rectangle you made, forming V-shaped notches that are about half an inch from each other. It may be easier to do one side of the “V” at a time, hacking downward slashes on the left half of the rectangle and then hacking upward slashes on the other side of the rectangle.\n5. Check the bucket every day. Collecting tree resin isn't instantaneous. You may have to wait several days for enough resin to collect. Keep the bucket under the tree and check on it daily. When it looks like you have about ¼ cup of resin, remove the bucket from the tree and transfer the resin to a small bowl. It should take two to three days to collect ¼ cup (60 ml) of resin.\n6. Use a double broiler to melt ingredients and form the wax. Use the same steps used to make cold-water wax, adding in the additional ingredient of ¼ cup (60 ml) of tree resin along with the beeswax and coconut oil in the top of the double broiler. The resulting wax will have a slightly stickier consistency than warm-water wax.\n\n\n## Put the wax in containers\n\n1. Pour the wax into a tin or container. Once the ingredients of the warm or cold water wax have fully mixed together, pour the wax into a container or tin large enough to fit it. Scrape the sides of the pan to be sure to get out all the wax. Use a tin or container that has a top so that the wax won't dry out.\n2. Let the surf wax harden. Before you close the container of surf wax, leave the wax out to harden for three to four hours or overnight. Leaving the container open lets the heat escape so that the wax can harden faster, and so its consistency stays the same.\n3. Use the wax or close and store the container. After the wax has hardened, it is ready for use. When you are done using the wax, place the lid on the container and store it in a cool place out of direct sunlight.\n"}, 5] | |

| [{"Instruction": "Explain how to create marbled fabric using traditional and shaving cream methods.", "Response": "If you like marbled paper, you might like marbled fabric too. It is surprisingly easy to create. The most traditional method uses carrageenan and water to create a thick base, but you can also use shaving cream instead. The traditional method takes a while to prepare, but the results are worth it. The shaving cream method is much faster, but it can get messy! Whichever method you choose, you are bound to end up with something unique and beautiful.\n\n## Use water and carrageenan\n\n1. Soak white fabric in a solution of alum and water the day before. In a bucket, combine 2 tablespoons (26 grams) of alum and 2 gallons (8 liters) of water. Soak your fabric in the solution for 20 minutes, then take it out. Wring out the excess water, then hang the fabric up to dry. Do not rinse the alum out of the fabric. Alum can irritate skin. It would be a good idea to wear gloves. Use white fabric that is lightweight and smooth in texture, such as muslin, cotton, light linen, or silk. Avoid heavy fabrics, such as canvas.\n2. Combine 2 tablespoons (10 grams) of carrageenan and 1 gallon (4 liters) of water. Mix the two together using a blender or hand/immersion blender. Start by mixing the carrageenan 1 teaspoon at a time into 2 cups (475 milliliters) of water, then add the solution to the rest of the water. It is best to prepare this in the pitcher to make the next step easier. Do not use the leftover alum water for this.\n3. Refrigerate the solution for 12 to 24 hours. You can do this at the same time as you are soaking the fabric in the alum. Once the 12 to 24 hours are up, take the pitcher out of the fridge, and let it come to room temperature, about 1 hour.\n4. Pour the solution into a large, plastic tub, and let it sit for at least 3 hours. The water is ready once it turns clear. The tub needs to be long enough and wide enough for the fabric to sit inside it, with at least a 1-inch (2.54-centimeter) border on all sides of the fabric the fabric.The water needs to be 1 to 2 inches (2.54 to 5.08 centimeters) deep. If you don't have enough water, you should make another batch.\n5. Dilute the acrylic paints with some fresh water. Choose 1 to 3 colors of acrylic paint, then pour each color into a small cup. Stir in enough water into each cup so that the paint takes on the consistency of heavy whipping cream. Do not use the carrageenan water for this.\n6. Place droplets of paint over the surface of the water. You can do this with an eyedropper or a pipette. Drop the paint close to the surface of the water; don't hold your hand high above it. You want the paint to float. If it sinks into the water, you are either dropping it from too high up, or the paint is too thick. If the paint is too thick, add some more water to it. Use a new dropper or pipette for each color.\n7. Swirl the paint drops together. There is no right or wrong way to o this. You can swirl the droplets together in a spiral with a toothpick. You can also drag a toothpick back-and-forth, then up-and-down through the water. You can even use a fork or a wide-toothed comb to do this.\n8. Gently lay the fabric on top of the water. Do not press the fabric into or under the water; you want it sitting right on the surface. If you see any air bubbles, gently poke them until the fabric lays smoothly against the surface again. If your fabric has a right and wrong side, make sure you are placing it right-side-down. Hold the fabric by the sides as you lower it onto the water so that the middle touches the surface first.\n9. Lift the fabric out and set it down onto a sheet of newspaper to dry. If you are worried about the ink transferring to the fabric, you can use blank newsprint or paper backs instead. At this point, you can dip another piece of fabric into the stray. You can also use a sheet of paper to collect the leftover paint, then drop and swirl new paint onto the surface.\n10. Allow the fabric to dry, then rinse it in cold water. Hang the fabric up to dry, preferably in the sun. Once the fabric is completely dry, rinse it with cold water, then hang it up to dry again.\n11. Iron the fabric after it dries to help set the paint into it. Cover the fabric with a tea towel or ironing cloth first, then pass an iron over it. Use a setting suitable for the type of fabric you are using (cotton, linen, silk, etc. ).\n\n\n## Use shave cream\n\n1. Wash the fabric using washing soda and hot water. This will not only remove any finishes that might prevent the paint from adhering, but it will also pre-shrink the fabric as well. Once the fabric is dry, you can press it flat with an iron, but this is not absolutely necessary. Cotton will work the best here, but you can use other, non-synthetic fabric as well.\n2. Coat a shallow tray with plain shaving cream. Spread the shaving cream around the tray so that you have a thick, even layer from edge-to-edge, corner-to-corner. For best results, use plain, white shaving cream, with no added dyes, oils, or perfumes. You will be spreading your fabric out in this tray, so make sure that the tray is big enough for it.\n3. Place drops of fabric paint randomly on top of the shaving cream. Try to space the drops randomly. Fabric paint will work the best, but you can use acrylic paint as well. If you are going to use acrylic paint, go for the bottled kind rather than the kind that comes in a tube; it is thinner and easier to drop out. Use one color for a simple effect, and two or three colors for a fancier effect. Use regular fabric paint. Don't use \"puffy paint\" or \"dimensional fabric paint.\"\n4. Swirl the paint around with a toothpick. Weave a toothpick through the shaving cream side-to-side and top-to-bottom. Feel free to add some spirals in there as well. Be careful not to over-stir the paint, however; you want the shaving cream to look streaky. You can also use other items to swirl the paint, such as pencils or chopsticks.\n5. Place the fabric on top of the shaving cream, then gently pat it down. Keep patting it until you can see the paint patterns appearing on the other side of the fabric. If your fabric has a distinct right and wrong side, set it right-side-down.\n6. Lift the fabric away and set it down on top of a trash bag. Make sure that you are setting it with the shaving cream side facing up. If you don't have any trash bags, you can use a plastic tablecloth, wax paper, or even a paper bag. Pull the fabric away at a slight angle rather than straight up. This will prevent the fabric from taking too much of the shaving cream with it.\n7. Scrape the shaving cream off. Hold the fabric down firmly by one end. Place a long, metal ruler on top of the fabric, with one of the edges facing down. Run the ruler across the fabric to scrape the shaving cream off. You may have to do a few passes; be sure to wipe the ruler clean before each one.\n8. Allow the paint to dry before heat setting it with an iron. Let the fabric out to dry, preferably in the sun. Once it is dry, place a tea towel or an ironing cloth over it, then iron it. Be sure to use a heat setting appropriate for the type of fabric you are working with.\n"}, 5] | |
| [{"Instruction": "How to handle a partner who refuses to talk during a quarrel?", "Response": "Here are some suggestions for your circumstance where your partner is reluctant to talk when you have a quarrel.\n\nFirst, ask yourself why you want your partner to talk when they don't want to. It is natural and healthy for people to need different amounts of time and space to process their emotions. If your partner is the type who needs a lot of time and space, pushing them to talk before they're ready will simply prolong the quarrel. You may very well be sabotaging yourself here.\n\nSecond, remember that you are not a mind-reader. You may think your partner is refusing to talk to you as a form of punishment, or to gain leverage in the argument, or any number of other reasons. But the only way to know why they are doing it is to ask them. You may not get a satisfying answer, but anything you learn will be better than the guesses you are making now.\n\nThird, if you are certain that your partner is simply trying to "win" the argument by refusing to engage, you have two options: you can withdraw from the argument, or you can engage anyway. If you withdraw, you may be giving up on something you want, but you also avoid the conflict escalating further. If you engage anyway, you may be able to convince your partner (or yourself) that you are serious about the issue at hand, and that it is worth discussing.

| [{"Instruction": "How to cook frozen chicken safely and efficiently?", "Response": "If you are in a rush, you may not have the time to thaw chicken for a meal. Luckily, you can save yourself some time and safely cook chicken from frozen. You can roast a whole, frozen chicken for a large group, or bake breasts or drumsticks for a smaller meal. Regardless of how much chicken you cook, it is important to always follow the safety guidelines for cooking chicken and thoroughly cook your meat to avoid any foodborne illnesses.\n\n## Roast a whole chicken from freeze\n\n1. Use caution when cooking frozen chicken. If you are cooking any parts of a chicken from frozen, there is an increased risk for foodborne illness. To kill any pathogens in the chicken, be sure to cook the meat to an internal temperature of at least 165°F (74°C). Always prepare from frozen chicken in the oven or on the stovetop and, as a rule of thumb, cook it about 50 percent longer than you would thawed meat. For example, it would take about two hours to roast a thawed 5-pound (2.25 kg) roasting hen at 350°F (177°C). If frozen, a similarly sized chicken would take about three hours to cook thoroughly at the same temperature. Check the internal temperature of the meat by inserting a meat thermometer into thickest part of the breast and the innermost part of the thigh and wing. If the thermometer does not ready 165°F (74°C), continue cooking the bird. Do not try to cook the frozen chicken in a slow cooker. The appliance will not get hot enough to kill the pathogens in the meat. It also leaves the meat sitting for too long at unsafe temperatures.\n2. Preheat the oven. Turn on your oven and heat it to 350ºF (177ºC). While your oven warms up, put the frozen chicken breast-side-up in a large roasting pan. This will ensure that the densest meat of the bird gets thoroughly cooked. Depending on the size of the chicken, you may also be able to use a Dutch oven instead of a roasting pan.\n3. Dress the chicken. If the bird is not frozen closed, try to remove the giblets from inside of the chicken. Once you remove the giblets, stuff the bird with your favorite ingredients, such as lemon, onion, rosemary, and thyme. Then rub the exterior of the chicken with olive oil and sprinkle it with salt and pepper. If you cannot access the inside of the bird, wait until it has cooked for about 45 minutes to remove the giblets. Use tongs and an oven mitt to remove the giblets and insert any stuffings that you want.\n4. Cook the chicken. Place the seasoned chicken in the oven uncovered and roast for about 90 minutes. Then increase the temperature of the oven to 450ºF (232ºC) and cook the chicken for another 15 to 30 minutes. This will help brown the skin. Remove the pan from the oven and serve once a meat thermometer placed into various parts of the chicken reads 165°F (74°C). These cooking times are based on a 4-pound (1.8 kg) chicken. Be sure to adjust the roasting time based on the weight of your chicken. Let the chicken rest for 10 to 15 minutes to cool before carving. If there is any pink or red meat, place the whole bird or uncooked pieces back in the oven until they turn white and there is no red in the juices.\n\n\n## Prepare bread chicken breast from freeze\n\n1. Freeze the breasts individually. When you bring the chicken breasts home from the grocery store, place them in single layer in a freezer bag. Make sure that there is some space between the breasts. If they freeze together, it will be hard to separate them and you will likely have to thaw them. You can also freeze the breasts flat on a plate or tray and then transfer them to a freezer bag. This is a good strategy for freezing any individual chicken parts.\n2. Preheat the oven. Preheat your oven to 425ºF (218ºC). While the oven warms, lightly oil a baking sheet. You can use olive oil, vegetable oil, or any other preferred cooking oil or fat. Then place four boneless skinless chicken breasts on the tray. If you are cooking frozen chicken breasts without breading, preheat the oven to 350ºF (177ºC).\n3. Add breading. As the oven warms, mix 1/3-cup (113 g) dry breadcrumbs, ½-teaspoon (3 g) salt, ¼-teaspoon (1.5 g) of black pepper, ¼-teaspoon (1.5 g) garlic powder with one tablespoon (15 ml) of cooking oil. Spread about one teaspoon (5 ml) of mustard on the top of the frozen chicken breasts. Then sprinkle the breadcrumb mixture onto the breasts, making sure that the mix sticks to the mustard.\n4. Bake the breasts. Place the tray in the oven and cook the breasts for about 30 to 40 minutes. Insert a meat thermometer into the thickest part of the breast to make sure that it is cooked thoroughly. If the temperature is below 165°F (74°C) or if there is any red or pink meat, put the breasts back in the oven and let them cook until they are white and the juices run clear. If you are cooking four frozen 4-oz (28 g) chicken breasts without any breading, you should cook them at 350ºF (177ºC) for 30 to 45 minutes. However, it is important to remember that the cooking time depends on the size of the chicken breasts.\n\n\n## Bake freeze chicken legs\n\n1. Season the legs before freezing. Because it is difficult to get seasoning to stick to frozen chicken skin, it may be easier to season your drumsticks before freezing them. Before you put them in the freezer, coat your drumsticks with your desired seasoning or rub. This will freeze the seasoning to the skin and make it easier to pull the legs from the freezer and toss them in the oven when you are ready to cook. This is a great way to season any individual pieces of chicken before you freeze them.\n2. Preheat the oven. Heat the oven to 350ºF (177ºC). While the oven warms, remove your drumsticks from the freezer and place them on a tray. For a side, you may also want to add some chopped vegetables like carrots and onions or a few sliced potatoes to the tray.\n3. Cook the drumsticks. Place the tray in the oven and cook the drumsticks for about 50 to 60 minutes. Once the time is up, insert a meat thermometer into the thickest part of the drumstick to make sure that it is cooked. If the temperature is below 165°F (74°C) or if there is any red or pink meat, put the breasts back in the oven and let them cook until they are white and the juices run clear. When you are taking the temperature of the drumsticks, try not to touch the bone with your thermometer. This will give you an inaccurate temperature.\n"}, 5] | |

This makes no difference, if the filter is symmetric, like a Gaussian, or a Laplacian. But it makes a whole lot of difference, when the filter is not symmetric, like a derivative. \nThe reason we need convolution is that it is associative, while correlation, in general, is not. To see why this is true, remember that convolution is multiplication in the frequency domain, which is obviously associative. On the other hand, correlation in the frequency domain is multiplication by the complex conjugate, which is not associative.\nThe associativity of convolution is what allows you to \"pre-convolve\" the filters, so that you only need to convolve the image with a single filter. For example, let's say you have an image $f$, which you need to convolve with $g$ and then with $h$. $f * g * h = f * (g * h)$. That means you can convolve $g$ and $h$ first into a single filter, and then convolve $f$ with it. This is useful, if you need to convolve many images with $g$ and $h$. You can pre-compute $k = g * h$, and then reuse $k$ multple times.\nSo if you are doing template matching, i. e. looking for a single template, correlation is sufficient. But if you need to use multiple filters in succession, and you need to perform this operation on multiple images, it makes sense to convolve the multiple filters into a single filter ahead of time."}, 4] | |

During your conversation with her, mention some place you're planning to be in the future so she can find you there if she chooses.\nFor example: "I like to grab lunch here before going to [Public Event You Enjoy]"\nThis could be almost anything, but here are some examples:\n\n* A place your band plays\n* A public dance\n* A painting/pottery class\n* A wine tasting\n\nThis should be something you actually enjoy, so be sure to let your excitement about your hobby be apparent when you mention it. Ex: "I enjoy that they let you try lots of different wines from all around the world!"\nIf she expresses interest in the activity as well, tell her more about it so she can attend: "Yeah, it's really fun. They do it every Tuesday and Thursday at 7pm - the admission fee is 5 Euro. You should check it out sometime!"\nIf she is interested in you and has time, she will probably arrange to come to the event some time and you will see her there. This is preferable because she is not under obligation to behave professionally for her work and you can spend some time chatting as equals.\nAnd if that goes well, then you have created a good opportunity to ask her on a real date.

| [{"Instruction": "Explain how environmental protection can support economic growth.", "Response": "The most important thing to remember here is that the two are not mutually exclusive. It is possible to have economic growth while also protecting the environment, and in fact in many cases it is necessary.\nFor example, pollution control is often seen as an impediment to growth, but in many cases it actually leads to it. Consider the Clean Air Act in the United States. When it was passed in 1970, many predicted that it would cripple the economy. In reality, while it did cause some short-term economic pain (as any transition does), in the long term the economy grew substantially, and the cost of compliance with the act was actually less than predicted. This is because a cleaner environment leads to a healthier population, which is more productive. It also leads to less sickness, which reduces healthcare costs.\nSimilarly, investment in renewable energy has been a huge driver of economic growth in many countries. And it creates more jobs than fossil fuel energy production.\nSo in most cases, protecting the environment and promoting economic growth go hand-in-hand. You can't have long-term economic growth without a healthy environment, because without a healthy environment, the economy will eventually collapse."}, 4] | |

| [{"Instruction": "How to help a child manage strong emotions effectively?", "Response": "That is a normal age for a child to be struggling with strong emotions. Many children do not learn healthy ways to cope with emotions, especially the big ones like anger, sadness, and fear. It is very difficult for a child to learn these skills without help. So, the best thing you can do is model good emotional control, and teach her how to deal with her emotions. Here are a few ideas:\n\n###Model & Teach\n* Talk about feelings. When you are feeling something strong, tell her. \"I'm angry right now because you didn't clean up your toys like I asked.\" Or, \"I'm sad that you are going to school today.\" Labeling feelings helps her learn to identify them in herself. \n* Talk about ways to handle feelings. \"I'm angry, and I don't want to yell at you. It makes me feel better when I take a deep breath and count to 10.\" Or, \"I'm sad that you are going to school today. It helps me feel better to give you a big hug and tell you I love you before you go.\" This teaches her ways to cope with uncomfortable feelings.\n* Help her label her feelings, and talk about ways to cope. \"You're screaming and throwing a tantrum. Is that because you're angry? Anger makes me feel mad. When I get mad I can feel my heart beat fast and my face get hot. It helps me feel better to stop and take a deep breath.\" This helps her learn to identify what she is feeling, and gives her ideas for how to cope.\n\n###Create Opportunities for Practice\n* Read books about feelings. There are many great books out there that talk about different feelings, and give ideas for coping.\n* Play games that involve feelings. There are games out there that involve identifying and talking about feelings. If you can't find one, make up a game where you describe a scenario, and have her tell you how someone in that scenario might feel.\n* Talk about what you see on TV or in books. When you are reading or watching TV, talk about how the characters are feeling, and how you know that. Talk about what you would do if you were in that situation, and ask your child what they would do. This helps them learn to empathize with others and think about different perspectives."}, 5] | |

Within the States and Territories of the USA, your voting rights depend on residence. If you leave the States and Territories your voting rights depend on former residence or inheritance.\n\nIn general most citizens of the USA are also citizens of a state of the USA. Since states don't issue their own passports, your citizenship of a state is determined by residence. If a New Yorker moves to Florida, they become Floridians, and so can vote in state elections in Florida, but can't now vote in elections in New York.\n\nNow if our New Yorker moves to Timbuktu, this is treated slightly differently. They remain a US citizen and a citizen of New York, and so retain the right to vote in New York elections. Their children could also claim New York citizenship.\n\nBut Puerto Rico is both part of the USA but not a State or part of a State of the USA. When our New Yorker moves to Puerto Rico, they can vote in Puerto Rican elections but not elections in New York.\n\nNow the nature of elections in the US is that there are no national elections There are statewide elections of Senators, Governors and Presidential electors. There are district elections of Representatives and there are local elections of many kinds. Our New Yorker has lost the right to vote in New York elections (just as they would have done if they had moved to Florida) but not gained the right to vote in Puerto Rican elections for Presidential electors (because there are none).\n\nThis is odd, but something similar is true if the New Yorker moves to DC.

| [{"Instruction": "How to flirt professionally with a coworker?", "Response": "Flirting with coworkers can relieve workplace tension and monotony. Some women flirt because they are interested in starting a romantic relationship with one of their coworkers. Others do it just for fun. Workplace flirting requires extra precautions because you must remain professional. You can still encourage some playful interaction between you and your coworker by engaging in friendly conversation, adjusting your body language, and dressing in a flirtatious but professional way.\n\n## Interact with your coworker\n\n1. Chat with them. Men tend to interpret friendly and talkative women as flirty. Find excuses to chat with them when they are not busy. Some things you can try:\n\t* Talk about hobbies, interests, and plans outside of work. \"Any big plans for the weekend? I've been dying to see this new movie myself.\" Praise their recent accomplishments or awards: \"I heard you just received an award! Any plans to celebrate?\" Ask them about current projects by saying, \"Hey, how is that current project going? Are you hanging in there?\"\n2. Laugh at their jokes. If your coworker makes a joke or says something even slightly funny, laugh. Laughing is a gentle way of flirting. It should not feel forced, nor should it seem as though you are laughing at your coworker.\n3. Compliment them. Appreciate the work that they do around the office, and praise them for their strengths. You want to make sure that you are appreciating their skills, abilities, and personality instead of their looks. Some good, flirty compliments include:\n\t* \"Great job on that last presentation. You'll have to give me some tips.\" \"Thanks for helping with that last project. You make my life so much easier around here.\" \"You have such good ideas. How do you come up with them?\" Be extremely careful with workplace compliments. If it seems as though the recipient is awkward or uncomfortable, stop immediately.\n4. Ask them for help. Asking people to help you can increase their self-esteem and confidence, which encourages them to flirt back with you. It also shows that you appreciate their strengths in a work-friendly manner. It can even encourage them to spend more time with you. Some ways you try this include:\n\t* \"Hey, you're good with technology, right? Can you help me with my computer?\" \"Do you mind listening to me practice my presentation? I'd love to get your feedback on this.\" \"Can you help me lock up tomorrow night?\"\n5. Hang out around their desk. Find excuses to drop by their desk. Perhaps you have a question about your project. Perhaps their desk is close to the coffee maker. As you pass by, make eye contact and ask them about their day. Walk by their desk, and try to catch their eye. If they look up at you, smile and ask, \"how's your day been?\" or \"Are you hanging in there?\" You can also ask, \"how is the work going? Do you want to take a coffee break?\" This gives them the opportunity to start a conversation if they are interested. Do not interrupt your coworker if they look as though they are busy with something else. Instead of being flirty, you might only annoy them.\n6. Invite them out to coffee or lunch. You may be feeling bolder, or you want to make the next step in your relationship. Instead of asking them to drinks or dinner, which can be too formal, try asking them if they would like to grab something to eat over your lunch break. Coffee is also a great way to bond with your coworker. A good way to ask is to just say, \"Hey, we should catch up over lunch. Do you want to grab a bite to eat somewhere?\"\n7. Respect their boundaries. Your first priority at work is to do your job. Be warned that flirting at work can get you in trouble if someone complains. If your coworker seems uncomfortable or asks you to stop, do not continue flirting with them. Give them space by only talking to them about work-related matters for a few weeks. Before you make any moves whatsoever, review your workplace sexual harassment rules, as well as rules about relationships in the workplace. You can also talk to someone in the HR department if you have any further questions. Make workplace friendly jokes that have no sexual innuendo. Never flirt with your boss. They are in a position of power, and any flirting can cause professional difficulties for both of you. It is best to flirt with coworkers on your pay grade. Do not flirt with a coworker who is married or in a relationship. Even if a married coworker enjoys your flirting, you are putting both of you in a difficult situation.\n\n\n## Express interest with body language\n\n1. Make eye contact. Eye contact is one of the primary tactics of flirtation. Brief glances can show your attraction and interest in another person. You can try looking across the room during a meeting or glancing across the table at lunch. Meet their eyes briefly before glancing down and away.\n2. Smile. Smiling is an open and friendly act that invites people to interact with you. In fact, smiling may be one of the best ways to meet new people and start new relationships. As your coworker passes your desk, glance up briefly and smile. If you catch their eye in a meeting, give them a quick grin. Don’t linger. A small smile is all it takes.\n3. Show off your neck. When you know they are looking at you, try to casually flip your hair to show off your neck. This shows the curve of your neck while drawing attention to your hair. This is a casual but flirty move that makes it seem as though you are not deliberately trying to catch their attention.\n4. Lean over their desk. Leaning or orienting yourself towards another person signals that you are interested in them. You can practice this while working on a project with your coworker. Lean over the desk to point out something. Reach out so that your arm is crossing their body without touching them. If you’re working on a shared computer, shift your body so that your feet and shoulders are tilted towards them.\n5. Avoid touching. While gently touching someone is often a form of flirting, it can get you in trouble in the workplace. Try to use body language that does not involve physical contact. If your touching is unwanted, you can get in trouble for harassment.\n\n\n## Increase your attractiveness\n\n1. Wear make-up. Many men find women who wear make-up more appealing. Men typically like to flirt more with women whom they find attractive, so making yourself more attractive is especially important if you want to flirt with a co-worker. Eye make-up in particular can increase your flirtatiousness.\n2. Put on heels. Heels can increase your attractiveness to men. The higher your heels, the more likely men are to approach you. High heels can push your pelvis and chest out, arch your backside, and make your legs look tighter and more muscular—all of which make you more attractive.\n3. Apply light perfume. Perfume can boost your sex appeal but only if it is used sparingly. Spray once on your wrists. Rub your wrists together before dabbing them on your neck. This will give you just enough perfume to attract someone without annoying your other colleagues.\n4. Maintain professional standards. While you should look appealing to your coworker, you must keep in mind that you have to look professional as well. Follow your workplace’s dress code. Avoid tight or short clothing that reveals too much skin. Instead, try to find clothes that fit your body’s shape without being too revealing. If you can, try using eye catching colors instead of revealing clothing. Wear jewelry to draw attention to your neck and arms. Make sure that your hair is brushed and styled in a way that both accentuates your features and provides minimal distraction to you while working.\n"}, 4] | |
| [{"Instruction": "Explain different techniques for modeling inheritance in relational databases.", "Response": "The different types of cars are an instance of a general problem that surfaces over and over again in data modeling. It is called \"generalization/specialization\" in ER modeling, and \"superclass/subclass\" in object modeling. \nAn object modeler uses the inheritance features built into the object model to solve the problem quite easily. The subclasses simply extend the superclass.\nThe relational modeler is faced with a problem. how to design the tables so as to emulate the benefits that one would get from inheritance? \nThe simplest technique is called single table inheritance. Data about all types of cars are grouped into a single table for cars. There is a column, car_type, that groups together all the cars of a single type. No car can belong to more than one type. If a column is irrelevant to, say, electric cars, it will be left NULL in the rows that pertain to electric cars.\nThis simple solution works well for the smaller and simpler cases. The presence of a lot of NULLs adds a tiny bit to storage overhead, and a little bit to retrieval overhead. The developer may have to learn SQL three-valued logic if boolean tests are done on nullable columns. This can be baffling at first, but one gets used to it.\nThere is another technique, called class table inheritance. In this design, there are separate tables for gas_car, electric_car, and hybrid_car, in addition to a combined table, car, for all of them. When you want all of the data about a specific kind of car, you join the car table with the appropriate specialized table. There are fewer NULLs in this design, but you do more joining. This technique works better in the larger and more complex cases.\nThere is a third technique called shared primary key. This technique is often used in conjunction with class table inheritance. The specialized tables for the subclasses have, as their primary key, a copy of the primary key of the corresponding entry in the car table. This id column can be declared to be both the primary key and a foreign key.\nThis involves a little extra programming when new cars are to be added, but it makes the joins simple, easy, and fast.\nSuperclasses and subclasses happen all the time in the real world. Don't be afraid. But do test your initial design for performance. If your first attempt is simple and sound, you'll be able to tweak it to speed it up."}, 4] | |

| [{"Instruction": "Explain how early photographic films evolved to capture colors accurately.", "Response": "Photo films and papers are made from salts of silver that naturally only darken when exposed to violet or blue light. In the early days of photography, this was all that was available. Therefore these films and papers are able to be handled under any light source that does not radiate blue light. By the way, the violet and blue frequencies of light are the shortest, and are the most energetic when it comes to inducing a chemical change. These early films and papers could all be be handled safely under red light as well as yellow light. These lamps do not emit violet or blue. \n\nThese blue-sensitive-only films did an OK job, with some exceptions. Women’s faces with cosmetics, like lipstick and rouge on the cheeks, came out weird. Warm tones reproduced super dark, and most times lips and cheeks turned black, void of detail on the finished picture. The bottom line is, many colors in nature reproduced incorrectly with this early blue-sensitive-only film. \n\nThe cure was accidental. Professor Hermann Vogel at Berlin Technical was trying to solve the problem of halation. This results when taking a picture of bright objects, like light sources or gemstones and the like. These objects play on the film with lots of light energy. This energy often goes completely through the film and hits something behind the film. The light is then reflected back into the film. The result is a halo around bright objects. The professor had one of his students dye the silver salts yellow, thinking the yellow dye would filter out the annoying reflected blue from the rear. He tried this dyed film and it did the trick, plus the film gained sensitivity to green light. He named this blue/green sensitive film orthochromatic (Latin for correct color). The year was 1857, and the quality of film reproducing the colors of nature moved forward by a big leap. \n\nA few years later, one of his graduate students, experimenting with different dyes, discovered how to make films sensitive to blue, green and red light. This film was called panchromatic (the pan prefix in Greek means \"all\"). Thus panchromatic film reproduces all colors found in nature with high accuracy. The bad news was, the darkroom folks were forced to give up the red and yellow safelight. A super dim green safelight could be used for a short period of time during developing. \n\nPhoto papers remained insensitive to red for the most part - no need, as they work OK with just blue and green sensitivity. Modern variable contrast photo papers have two sensitive coats, one for blue light and one for green light. We can use a safelight on these papers; it is amber with reduced brilliance. \n\nFilms and papers that make color pictures are panchromatic, and most safelights are not safe. We can use infrared lamps with a specialized night vision infrared scope to view and handle most panchromatic films and papers, because these materials have low sensitivity to infrared."}, 4] | |

| [{"Instruction": "How to overcome workplace loneliness and improve engagement?", "Response": "Many people spend a large percentage of their lives at work. This can feel terrible if you are one of many people who feel detached and disengaged within the culture of their workplace. Workplace loneliness can impact your performance and engagement, so overcoming the feeling of not belonging is central to your success. Knowing how to connect with people at work is also an important professional skill that can help your career. Manage the feeling of being out of place at work by trying to figure out what caused it, making an effort to interact, and finding solutions for disengagement.\n\n## Address the feel\n\n1. Try to label what you're feeling. Ask yourself what is keeping you from belonging. Co-workers sometimes hang out with their own age group by default and maybe you're much older or younger. Perhaps you are a manager and feel excluded from your subordinates?Maybe everyone else has energy for the job, but you're dealing with burnout. There even may be varying levels of lifestyles, values, or interests separating you and your colleagues. Sit down with paper and a pen and try to list whatever reasons come to mind. After you make a tentative list, you can spend a few days observing yourself and your peers at work to see if your reasons are accurate.\n2. Change your internal dialogue. Sometimes, the biggest roadblock keeping you from connecting with people is in your own head. If you keep telling yourself you don't fit in, you won't. Your thought patterns can lead to a self-fulfilling prophecy in which what you believe about yourself becomes true. If you're thinking you don't belong, you're awkward, or people won't like you, reframe your self-talk. Create a list of positive, realistic statements about your workplace connections, such as “I have much to offer as a friend” or “I enjoy the culture of my workplace, so I am certain to find people with common interests.”\n3. Consider any constructive criticism you have received. If your boss or a peer has recently expressed concern that you are not a team player, dominate conversations, or bring a toxic competitive vibe to the workplace, you may need to dial it back to feel like a part of the group. If you shrugged off their feedback without trying to make positive change, they may be excluding you on purpose. If this describes your circumstances, you have two options: you can stay the way you are and remain excluded or reflect on their feedback and find ways to improve. It's up to you, just know that if you choose to stay the same, you could be hurting your reputation and growth within your career.\n4. Get help. Your engagement at your job has a major influence on your career growth and life satisfaction. If you can't seem to identify what's keeping you from fitting in, you made need to seek out professional assistance. If you are struggling with self-esteem issues or social anxiety, you should see a mental health expert. If you are dissatisfied with your choice of work or feel like your workplace does not align with your values, it may help to see a career counselor. Look into leadership or self-help workshops to get help with specific areas of personal development. One good option for leadership and self-improvement training is called Landmark Education.\n\n\n## Attempt to interact\n\n1. Set a daily conversation quota. Not belonging doesn't feel good, so even if you don't make any major changes, it can still make you feel better to interact more often. Make a personal goal to have one or two conversations with a peer at work each day. Think of some conversation starters to make it easier. Increase your chances of conversing by hanging out with your co-workers more. If they eat in the break room, don't take your lunch at your desk or work-station. Join them. Then, listen to their discussion and participate when you have something of value to add. For example, your co-workers are discussing vacation plans and one of them mentions a trip to a specific location. If you have an interest in that place, you might say, “That sounds so exciting! What sorts of excursions are you planning during your visit?”\n2. Focus on the other person, not on your own shyness. If you are shy or hesitant about chatting it up with your co-workers, follow this rule-of-thumb: don't dwell on how shy you feel, turn your attention completely to the other person. Act as if you are serving them in a way—try to make them smile or laugh, get them talking about their own life. When you're worried about how you're coming off to others, you might over-analyze and end up ruining a perfectly decent interaction. Take a break from focusing on yourself and devote your attention to the other speaker. Make sure to ask open-ended questions to keep the other person talking. These are questions that invite elaboration and that don't have a simple yes or no answer. Be willing to share about yourself as well to keep the conversation going and to form a genuine connection.\n3. Don't turn down invitations. If you're notorious for responding with “no” each time your peers invite you to lunch or to after-work drinks, they'll quickly stop asking. No one wants to be rejected over and over again, so you may have inadvertently caused them to exclude you. When you catch them discussing plans, ask if you can tag along. Or, if someone directly invites you, try to say “yes” unless you absolutely cannot go. Practicing saying yes to invites can improve your work life and your personal life. Accept a set amount of invitations per week and invite people to do things as well.\n4. Ask a co-worker out for coffee or similar. If the group as a whole makes you self-conscious, target one particularly non-intimidating, friendly co-worker. Making just one social connection at work can help you feel less isolated. Plus, once this person gets to know you, they might encourage the others to do the same. Say something like, “Hey, Carla, I enjoyed our talk earlier. It's refreshing to talk to another newbie mom. Would you like to get coffee together one morning before work?”\n5. Suggest to your boss the idea of workplace socials. If your workplace culture doesn't emphasize inclusion, you might not be the only one feeling left out. Make a recommendation to your superior to stimulate connectedness with group events. Plan a potluck lunch or dinner to celebrate a company victory. Start a baseball, cricket, soccer, netball or basketball team.\n6. Seek advice about purposeful exclusion. Maybe your co-workers seem to have a vendetta against you, overlooking you for social outings and never including you in workplace gift exchanges. If this is the case, you will have to carefully consider how you choose to move forward. The best thing to do is to talk with someone you trust at your workplace about what has been happening. It can also help to first share your worries with a trusted friend. You might say, \"I get the sense that I am the odd one out at work. They never include me. And they stop talking whenever I come around. What should I do?\" Even if you don't take your friend's advice, it can help to have some unbiased support.\n\n\n## Deal with disengagement\n\n1. Resist acting out to get attention. Studies show that when an employee feels excluded, they may engage in acting out behaviors to get noticed. Examples might include cutting co-workers out of projects, cheating, lying, or aggressively competing. If you are tempted to behave this way, think about the possible repercussions first. Acting out will only make you feel more excluded, and it could jeopardize your job too.\n2. Set an objective workplace goal. Chances are you could be disengaged from work because you no longer feel challenged. Simply because your job description doesn't entail any lofty accomplishments or goals doesn't mean you can't strive for them. Create your own personal goals to work towards. This could be just what you need to feel passionate about your work and reconnect with the group. For example, you might aim to get so many reports done by 5pm each day. Or, you might develop a track to move towards a promotion or transfer to a new company. Try to focus on what you can control and avoid trying to control things that are outside of your control.\n3. Reevaluate the job. If the work you do and the people you do it with leave you feeling lackluster, you could be in the wrong career. If you have to change the way you act, undermine your values, or fantasize about leaving your job each day, pay attention to these cues. The culture of your workplace is just as important to your satisfaction as the actual position and salary. It may be time to quit. Re-examine why you got onto this career path or took this job.\n"}, 4] | |

You are supposedly handled on a first-come-first-serve basis (reality is slightly different with different aircraft speeds, etc.). Do the airlines like it if you slow them down? No, but it's part of the system and the way that it works.\n\nVery often, there are multiple runways at bigger airports, and sometimes there are even shorter runways that are dedicated for airplanes that don't need to land on the same one as the \"big boys\". Even if not, they will work you in.\n\nNow, that being said, very often there is a better option. As you said, there are usually high fees at the big airports, so landing at a smaller satellite airport can often save you money and save you time because you won't have to taxi as far or sit and wait in line to get out. An extra 15 minutes by car can be better than an extra 30 minutes while taxiing. \n\nAs far as being prepared, it isn't really much different than smaller airports other than the fact that ATC is much busier. They don't have the time/tolerance to keep repeating instructions to you, and expect you to be \"on your game\". When they rattle off taxi instructions like \"Cessna N1234, taxi to the ramp via Alpha, Tango, Echo, and Xray. Hold short of runway 23.\" they expect a quick readback and for you to follow instructions exactly because they need to move on to the next guy. \n\nIt will also help everyone out if you don't fly your final approach the way that most people are taught for an entire 10 mile final: very close to your actual landing speed. In fact, you are usually landing on a runway that is 4X+ the distance that you need and you can slow down fairly quickly (especially compared to a jet), so if you can fly an extra 20 (or 80) knots as long as possible, it will be greatly appreciated and keep traffic moving.

So they killed him for having the audacity to change so much.\nAnd that's the lesson to be learned, kids: if you do too much with your life, then you'll make too many enemies."}, 3] | |

A rabbit can fill up on it (because of the bulk), but still need food because they didn't get enough calories, vitamins, minerals, etc.\nIf you look at the USDA's webpage on iceberg lettuce. You'll notice that water makes up just about 95% of the nutrients, leaving 5% to be divided up between every other nutrient. Protein is a little less than 1%, Carbohydrates less than 3%, and sugars less than 2%.\nMost importantly, you want to pay attention to the vitamin and calorie content. Iceberg lettuce has only 14 calories per 100 grams (2 calories or less in each leaf), and 18mg of calcium.\nOther effects to consider, is when fed straight from the fridge, lettuce will be cold and wet, both are conditions that can upset a pet's stomach.\nIn addition, since most rabbit breeders do not feed lettuce to their baby rabbits, it is an unfamiliar food and if the rabbit owner does not add lettuce to the diet gradually, it will cause stomach upset.\nFinally, it is often believed amoung rabbit breeders that\n\nRabbits should not eat some lettuces (such as iceberg) as they contain a substance called laudanum which can be harmful in large quantities.\n\nRSPCA: Rabbit Diet Myths\nBut this is disputed because\n\nLettuce does not contain laudanum. Edible lettuce does contain a chemical called lactucin which is a component of lactucarian. Lactucarian is the milky fluid found in some species of lettuce and occurs in much larger amounts in wild lettuce, Lactuca virosa.\nLactucarium has sedative and analgesic effects. It creates a sense of mild euphoria. The milky exudate resembles that of opium and it can also be reduced to a thick substance which can be smoked in the same way as opium.

The discovery of any new species is big news, but the discovery of a population of new species that are dinosaurs would be the biggest scientific discovery of all time. Paleontologists would fight tooth and claw to be the first to study them. The island would be immediately declared a nature preserve and probably a UNESCO World Heritage Site. The country that owns the island (if it's a country that has a good relationship with the scientific community) would be overjoyed at all the scientific attention and would do everything they could to help the scientists study the dinosaurs.\n\nSecond, the public would also go nuts. It would get a lot of media coverage. There would be huge demand for tours to the island, as much to see the dinosaurs as to see the amazing new species of plants and other animals that would almost certainly be found there as well. The country that owns the island would be overjoyed at all the income from tourists and would do everything they could to set up tours, as long as the scientists didn't object too strongly.\n\nThird, there'd be a lot of debates about whether to clone them, whether it was ethical to bring them back to civilization and what impacts they would have on the ecosystem and society.\n\nOverall, the discovery of live dinosours is a momentous event and it needs lots of discussions and careful actions to figure out what is the best way to manage the dinosours."}, 3] | |
| [{"Instruction": "How to travel with less stress and more relaxation", "Response": "## Prepare for low-stress travel\n\n1. Prepare a packing list ahead of time. Packing your bags can be one of the most frantic and stressful aspects of travel–not to mention one that’s often left until the last minute. To slow down this aspect of your traveling, create a packing list months in advance of your trip. Write down travel necessities (clothes, passport, computer) first, and add new items to the list when they come to mind. Don’t throw away your list after you return from your trip. A well-made travel list can serve you for years, since you’ll typically take the same items with you from one trip to the next. Consider laminating your packing list and placing it in your suitcase or backpack, so you won’t have to search for it each time you’re planning a new trip.\n2. Pack well in advance, and travel light. To slow down the speed of your travel preparation and to avoid stress, start packing in advance. Although some items—such as clothes and toiletries—may need to be packed the day before you leave, others can be set aside weeks in advance. This will allow you to pack more slowly, and decrease travel-associated stress. As a busy traveler, it’s also important that you travel light. This will help you move with less stress through busy airports, security lines, and bus terminals. Packing light will also help you focus on the places you’re traveling to see, as you won’t be weighed down by several heavy bags. Only focus on bringing the essentials; you can always pick up incidental objects on your trip.\n3. Consider booking through a travel agent. Especially if you’re planning a long trip—or several short trips—with multiple destinations, hotel stays, rental cars, and other logistics, plan to talk with a travel agent. Although the profession may seem outdated, an agent can put together all of these bookings for you, so that you’re not searching through countless travel websites on your own time. For long, complex trips, working with a travel agent could also save you money. Your travel agent may be able to find lucrative deals that you wouldn’t have access to, or may know ways to package flight, hotel, and rental car purchases together to decrease the cost.\n\n\n## Slow down while you’re travel\n\n1. Let the hotel front desk staff do some of the work. A large part of the headache of fast-paced travel comes from the plethora of details that can consume your time and generate stress. Rather than micro-managing each detail yourself, seek assistance from the front-desk staff or hotel concierge. For example, ask the front desk of your hotel to make you a dinner reservation, call you a cab, or put together an outline of a travel plan for a day. Especially if you’re traveling with children, you’ll need to rely on others around you to make your trip less stressful and busy. Ask the front desk staff for restaurant recommendations, and recommendations of local activities that are fun for children.\n2. Schedule in “required” extra time for delays. As a busy traveler, you’ll often have a tight schedule to keep: flight times, bus schedules, and train timetables may be your first priority. However, delays are an unfortunate but inevitable part of travel. Slow down your travel schedule by allowing extra time around all plane, bus, and train travel, and you’ll find yourself feeling less busy and enjoying your travel time more. By accepting that delays are a part of travel, you can save yourself stress and worry. You can also pan to be productive during your delays—call ahead to alert the hotel that you’ll be arriving late, or if you have a longer delay, walk around a local neighborhood to absorb the culture.\n3. Plan to do fewer activities. This may seem like an intuitive step, but it’s one that many busy travelers forget. Rather than filling your time when you’re traveling with a dozen plans, which will leave you feeling rushed and drained, simplify your trip and only do the three or four activities that you’re most excited about. For example, if a city is known for its world-class art museum but you’d rather spend the day exploring a local forest, don’t feel obliged to do both. Stick with the forest. Filling your time with fewer activities—but ones that are more interesting, pleasurable, and meaningful to you as an individual—will help you slow down your travel pace. This will allow you to savor and enjoy each activity more.\n\n\n## Use slow-paced travel methods\n\n1. Slow down your method of travel by staying on the ground. If you’re used to traveling primarily by plane—a fast-paced, high-stress mode of travel—look into alternate options. For example, a road trip is a great way to see local attractions and parts of a country or region that you haven’t visited before. A road trip also allows you to slow down and travel at your own leisurely pace. If you’ve never traveled by train, it can be an excellent way to slow down the pace of your travel and have more local-color experiences while traveling. Train travel moves at a leisurely pace, and you won’t have to worry about catching connecting flights or navigating unfamiliar—and stressful—airports.\n2. Take a local approach and travel somewhere nearby. You can also slow down the busy pace of your travel by focusing on in-depth exploration of a single local city, town, or region, rather than traveling across the country or world. Treating your own local environment like a travel destination will allow you to absorb local color that you haven’t noticed before, and you’ll be able to avoid the stressful tourist traps that draw inexperienced travelers in new cities and countries. As long as you’re traveling locally, you can try eating locally too. If there’s a farmer’s market open in the area, do your shopping there; you’ll doubtlessly be surprised by the varieties of local food that you’ve never sampled before. You don’t have to stay in your own house to explore a local area. Look into local AirBnBs, traditional Bed and Breakfasts, and “mom and pop”-type hotel: say, within 30 miles of where you live.\n3. Take an affordable cruise. A cruise offers many conveniences that will help you keep your travel slow paced and not too stressful. The cruise ship will offer you a “home base” to start your daily explorations from, so you won’t have to worry about rushing from hotel to hotel, or from AirBnB to AirBnB. Cruise ships tend to travel at a moderate pace, giving their customers plenty of time to explore local cities and sites. The cruise will also confine you to a single region, which is beneficial to a slow-paced, low-stress travel plan. To book a cruise, first check large travel websites, including Expedia and Priceline. You can also book cruises directly through the websites of large providers, such as Carnival and Royal Caribbean Cruise. If you travel with several family members or friends, the cruise line may offer you a group discount. Cruises can be surprisingly inexpensive, especially if booked for the off season.\n"}, 4] | |

| [{"Instruction": "How to reduce cellulite appearance naturally and effectively?", "Response": "Have cellulite? Don't worry: Almost all women have it. However, few if any women want it. There are ways you can reduce the orange peel-like dimpling that occurs on the skin, usually on the legs, thighs and butt. It’s a myth that cellulite is always tied to obesity. Some thin people still have cellulite. However, your chances of cellulite grow with obesity, so exercise and choosing a healthier diet matters.\n\n## Make cellulite less obvious\n\n1. Get a tan. Whether it’s a spray tan or a natural one, tanned butts and legs don’t show cellulite as much. If you already have a dark complexion, you’re lucky because darker skin doesn’t show cellulite as much as pale skin does. Always take caution when tanning, though. The sun’s rays can lead to skin cancer, so it's usually a better choice to get an authentic looking fake tan. There are many ways to do this: airbrush or booth spray tanning at a salon and home products such as foam, lotion, or spray. When applying tanning lotion, start by exfoliating the skin with a body scrub, as well as shaving any areas where you don't want hair. Then, using gloves, apply the lotion all over your body, starting with the head area, and taking care not to get it into your eyes. Apply petroleum jelly to your eyebrows to prevent them from becoming discolored. When spray tanning, it’s very important that you wear recommended protective gear (over eyes, nose, and other body openings) so you don’t ingest the tanning particles during the process. If using a booth, you will be instructed to turn inside the booth as a nozzle sprays you with the solution.\n2. Start toning your legs. While genetics might make you more susceptible to cellulite, toned legs with strong muscle definition tend to show cellulite less. Run up a staircase, go for a long walk or jog, and use a stair master or elliptical trainer. All of these exercises and equipment target the leg and butt areas where cellulite resides. Contrary to popular myth, cellulite is not caused by toxins in the body. It’s caused by a lack of exercise and muscle tone, excess fat, poor circulation, genetics and hormones. Leg lifts and squats are among the exercises that can help you tone your legs.\n3. Strength train. Although running and other cardio can reduce your weight, which can make cellulite less obvious, strength training will be best at getting rid of the dimpled look. Yoga routines help tone the body and reduce the appearance of cellulite, as do strength-training routines that build muscle. Studies have shown that people who combine cardio with strength training (weight lifting, some circuit training routines) added muscle in addition to losing fat, and improved the overall look of their bodies. As little as 15 minutes of cardio (such as running) and 15 minutes of strength training (such as weight lifting) three times a week can make a difference over time (at least eight weeks).\n4. Try anti-cellulite clothing. It doesn’t work for everyone, but some clothing manufacturers make clothing marketed to reduce the look of cellulite. These pieces of clothing, such as capri leggings, are designed to generate heat that in turn helps break down cellulite cells. Elastic underwear has the opposite effect; it can make cellulite look worse. Wear non-elastic undergarments made of smooth fabric. Loose fitting clothing helps reduce cellulite because tighter clothing impairs blood flow throughout the day.\n\n\n## Improve the diet to reduce cellulite\n\n1. Drink a lot of green tea. Green tea has many health benefits. Some people drink it as part of weight reduction efforts, but it can also reduce the sight of cellulite. Green tea is a good choice for people who find it boring to drink plain water all day long. You can drink it cold or hot. Green tea doesn’t add many calories to your daily intake, but it’s very rich in antioxidants. The tea will increase your metabolism. Cellulite can occur with age because it’s associated with lower production of estrogen in the body. Drinking a lot of green tea can help reduce this effect. A faster metabolism means that your body should be able to expel toxins faster, which will reduce the look of cellulite.\n2. Drink a lot of water. There are many, many proven benefits to guzzling water. You should drink water all day long. Stay hydrated. Hydrated bodies won’t have cellulite that looks so obvious. Other health benefits include shinier hair and younger looking skin. If you find drinking plain water too boring, add a lemon slice into it. It’s a good idea to drink two liters of water every day and to drink water constantly throughout the day. Drinking a lot of water can also help with weight loss, which can further reduce cellulite. That’s because when people feel hungry, sometimes it just means they are dehydrated.\n3. Avoid sugary beverages. Drinking beverages loaded with sugar will probably make cellulite worse (not to mention it can increase your weight). That means you should avoid carbonated sodas but also be aware of drinks that have hidden sugars, such as fruit juices. Study labels. Some beverage companies are experts at packaging and marketing and they might make you think that energy or fruit drink is healthy – until you read the label and see that it’s loaded with sugar and carbs. It’s always better to choose water than sugary beverages. Even diet sodas aren’t great for the body because they have carbonation and chemicals.\n4. Try natural remedies. There are many natural remedies that some people swear help with cellulite. Give one of them a try and see if they work for you. Refrigerate the residue from your coffee grinds (black coffee). Mix them with olive oil to create a scrub that you apply to the cellulite-impacted area. Use circular motions to apply the rub for about 15 minutes. Then, leave the grinds on your body for about 15-20 minutes more before washing them away. Cover and warm the region with shrink wrap. Instead of coffee grounds, you could use salt and grapefruit juice to create a similar rub that some people say helps with cellulite.\n5. Eat healthier foods. Reducing the amount of toxins in your diet is good for many reasons. You will likely lose weight, be healthier, and your cellulite will reduce. Consume alkaline forming foods. Alkaline is found in fresh fruit and vegetables, which should make up the majority of your diet if you want to eat healthier. Sprinkle flaxseed on your breakfast to boost collagen growth. Sprinkle two tablespoons of it on oatmeal or yogurt. Fresh vegetable juicing is one way you can flood your body with healthy juice. Avoid eating processed foods as much as possible, especially foods that come in boxes and that are loaded with carbohydrates or sugar. Drink lemon juice and cayenne pepper three times a day.\n6. Eat kelp. Kelp can help you lose weight as well as improve the appearance of cellulite. It contains a chemical found in green plants that helps the body burn fat. Purchase dried kelp and add it to stir fries, soup or salad. You can also ingest kelp vitamins. Consider kelp \"sea vegetables.\" The kelp retains the minerals that are found in the ocean, making it very healthy for you. Kelp, sometimes called seaweed, also balances out the thyroid gland, improving your health. It's often found in Asian cooking.\n7. Stay away from too much salt or sugar. Salt and sugar can lead to serious health problems, as well as obesity, which makes cellulite more obvious. Avoid eating too much refined salt. Crystal and sea salt are healthier. Refined salt dehydrates the body and leaches minerals out of it. Sodium also causes the body to retain fluids, making cellulite look worse. Sodium can harm your health. Try to limit your sugar consumption to 6 teaspoons a day and your salt consumption to 200 mg of sodium.\n\n\n## Use chemical and other tool to reduce cellulite\n\n1. Try lasers. Some beauty salons and plastic surgeons offer treatments for cellulite that use lasers and other mechanical devices. There are downsides to these methods. They are often expensive, they need to be repeated regularly, they have to be done by a trained professional and can be painful. One example: Cellulaze is a procedure approved by the FDA for cellulite. A small laser is inserted under the skin to break down the cellulite’s structure. Research carefully any such interventions and check into the licensing and ratings of the salon performing the functions, as well as the credentials and training of the person administering it. Laser toning and cold-laser massage are also techniques that are said to reduce the appearance of cellulite. The tri-active laser was approved by the FDA and claims to temporarily reduce cellulite’s appearance. Fillers are sometimes used to treat cellulite dimples.\n2. Try a lotion. Many products advertise that they can help improve cellulite. Not all are that successful, but you could give them a try. You might find temporary help from ingredients that dilate blood and lymph vessels. Black pepper, green tea, ginger, cinnamon, cayenne pepper, and ginkgo fall into this category, and some anti-cellulite creams contain them. Ointments containing forskolin (which comes from the herb coleus forskohlii) were found in one study to help women lose excess skin from their thighs. Skin firming cream can help build up collagen and diminish wrinkles. Some cellulite creams contain retinol, coenzyme Q10, and vitamin C. Major brands like Lancome, L’Oreal, and Nivea offer gels and lotions that are said to firm up the skin.\n3. Massage the affected area. Not only do massages feel great, but they are also known to reduce the look of unsightly cellulite dimples. Use a body brush with boar or just stiff bristles in a circular motion while you take a shower. Or use a hand-held massagers. Apply the massage head to the areas with cellulite. Add a skin firming serum, body lotion or anti-cellulite gel before you apply the massaging motions. Cellulite is caused by fat deposits that push through the skin’s connective tissue, usually in the buttocks and thighs. Massaging the skin stimulates the lymphatic system that lies right underneath the skin’s surface. This circulates toxins and causes the body to release them more quickly. Add a few drops of olive and juniper oil to the skin before massaging it.\n"}, 4] | |
| [{"Instruction": "Explain the reasoning behind C's declaration syntax.", "Response": "Dennis Ritchie’s paper on The Development of the C Language gives some idea of the reasoning behind this: namely, the fundamental rule in C that declaration syntax should match expression syntax\"\n\nFor each object of such a composed type, there was already a way to mention the underlying object: index the array, call the function, use the indirection operator on the pointer. Analogical reasoning led to a declaration syntax for names mirroring that of the expression syntax in which the names typically appear. Thus,\n```int i, *pi, **ppi;\n```\ndeclare an integer, a pointer to an integer, a pointer to a pointer to an integer. The syntax of these declarations reflects the observation that ```i```, ```*pi```, and ```**ppi``` all yield an ```int``` type when used in an expression. Similarly,\n```int f(), *f(), (*f)();\n```\ndeclare a function returning an integer, a function returning a pointer to an integer, a pointer to a function returning an integer;\n```int *api[10], (*pai)[10];\n```\ndeclare an array of pointers to integers, and a pointer to an array of integers. In all these cases the declaration of a variable resembles its usage in an expression whose type is the one named at the head of the declaration.\n\n\nIt appears this rule trumped parser considerations. Its immediate consequence is that function declarations can’t use specific keywords, or impose a different ordering of declaration components.\nIt’s worth noting that parsing was somewhat different in early C, since function declarations didn’t specify their arguments, and function definitions separated the argument list from the argument declarations (which weren’t necessary for ```int``` arguments):\n```sum();\n```\ndeclares a ```sum``` function, which would then be defined as\n```sum(a, b) {\n return a + b;\n}\n```\n(no types needed here, the default is ```int```). So the parser didn’t deal with types inside argument lists."}, 5] | |

| [{"Instruction": "Explain how prions resist digestion and enter the body.", "Response": "Proteases are enzymes in your digestive system that help break down food, acting like molecular-sized scissors that cut up proteins.\n\nProteases have clefts, or subpockets, into which proteins fit, where the substrate (protein) gets cut.\n\nInfectious or pathogenic prions are resistant to proteases, because of their three-dimensional shape, which hides away parts of the prion that would normally fit in proteases and which would cause the prion to be digested.\n\nPrions that do not cause disease — normal prions — have a different three-dimensional shape that allow them to fit into proteases, and so they are not resistant to digestion:\n\nA wealth of evidence contends that the infectious pathogen causing the prion diseases, also referred to as spongiform encephalopathies, is solely comprised of PrPSc, the pathogenic isoform of the prion protein (21-23). Both PrPSc and its normal cellular counterpart, PrPC, are encoded by a cellular gene (2, 19). Physical and molecular characterization of PrPSc and PrPC has failed to reveal any chemical differences between the two isoforms (32). However, PrPSc acquires distinctive conformational characteristics upon its conversion from PrPC. Whereas PrPC is soluble in most detergents and can be easily digested by proteases, PrPScis insoluble in detergents and maintains a protease-resistant core, designated PrP27-30, which polymerizes into amyloid (25).\n\nDr. Neena Singh also discovered that prions "piggyback" or attach to another protein called ferritin, as they make their way through the digestive system:\n\nDisease-causing prions are thought to have passed into people when they ate beef from infected cattle, triggering the brain wasting condition called new-variant Creutzfeldt-Jakob disease, or vCJD. But researchers have not been sure exactly how prions enter the body.\nTo find out, Neena Singh and her team at Case Western Reserve University in Cleveland, Ohio, mimicked the process of eating and digesting infected meat.\nThey mashed up brain tissue that contained prions from patients who had a form of Creutzfeldt-Jakob disease. They then exposed it to a range of harsh digestive enzymes from the mouth, stomach and intestine, which normally break proteins into pieces.\nPrions, which are known to be enormously tough, escape this attack almost unscathed, they showed, as does a second type of protein called ferritin, which stores iron and is abundant in meat. The two proteins seem to stick together, they report in the Journal of Neuroscience.\nThe researchers next added the digested slurry to a lab model of the human gut: a growing sheet of cells from the intestinal lining. By attaching fluorescent tags to the two proteins, they showed that they are transported through the cells hand-in-hand. "Prions probably ride piggyback" through the gut wall into the body, Singh says.\n\nAttaching to ferritin may provide additional protection from digestion, insofar as this removes prions from the digestive system, where proteases are concentrated."}, 3] | |
| [{"Instruction": "Explain the relationship between science fiction and fantasy genres.", "Response": " Any sufficiently advanced technology is indistinguishable from magic.\n - Arthur C Clarke\n\nThere's a reason that science fiction and fantasy are frequently shelved together - separating the two is usually a fools errand.\n\nThe Dragonriders of Pern features a preindustrial society where flying, firebreathing, teleporting, and telepathic dragons defend the skies from horrible creatures that rain down from above. They could easily be considered pure fantasy - up until the book where they discover the spacecraft that the human ancestors flew in on, and the labs where they bioengineered the dragons. \n\nIn Star Wars (arguably the most famous science fiction property of all time), the Force is really just space magic called another name. And they do all their fighting with swords. \n\nThe lists go on and on. Science fiction and fantasy are united in that they explore the impossible. Fantasy uses elements that will never be possible, while science fiction uses elements that theoretically might be possible. But the impossibility is shared. \n\n## Science fiction and fantasy are not a single genre - they are many\n\nEpic fantasy (eg Wheel of Time) and space opera (eg Star Wars) are more similar to each other than they are to urban fantasy or \"hard\" science fiction. \n\nIn some ways, it's inaccurate to call science fiction and fantasy genres at all. They're setting elements. A romance doesn't stop being a romance because it's set on a space station, and a murder mystery isn't any less mysterious because it was an elf who was murdered.\n\nThe key to mixing these elements successfully is to understand the expectations of your readers, and meeting those expectations (but in surprising ways). Genre helps define expectations.\n\nIf you're writing hard SF, readers expect to see a world that's close enough to our own that they can believe that our world could become the world of the story - magic obviously has no place here. \n\nOn the flip side, urban fantasy readers expect the author to have considered the modern world and how it might interact with the impossible. Extrapolations from science to science fiction may be natural depending on the exact nature of the setting.\n\nIf the reader has led to expect that the serial killer is a Scooby-Doo villain, then the sudden reveal that the murders were done with actual magic will violate their expectations and frustrate them (in general - there will of course be exceptions). But if the story is framed as a space cop trying to capture a vampire despite not believing that vampires are real, the readers will accept that premise as well as any other. "}, 4] | |
| [{"Instruction": "Tell me how to make homemade ricotta cheese", "Response": "Ricotta cheese, the delicious key ingredient in Italian dishes from lasagna to cannoli, is simple to make in your own kitchen. Homemade ricotta cheese requires just a few ingredients, and the result is lighter and fresher than store-bought cheese. See Step 1 and beyond to learn how to make a batch today.\n\n## Milk-based ricotta\n\n1. Prepare the strainer. Line the fine-mesh strainer with a large piece of cheesecloth, and set it over the nonreactive bowl. Set this contraption on your work surface so to have it ready for the cheese mixture. If you don't use cheesecloth, it will be difficult to separate the cheese curds from the whey. You can substitute a double layer of paper towels or a thin cotton dishcloth in a pinch.\n2. Heat the milk, cream and salt. Place the milk, cream and salt in the saucepan and heat the mixture over medium-high heat. Allow it to heat until it reaches 200 degrees F. When the mixture is hot enough, turn off the heat and move the saucepan so the milk can begin to cool. It should take about 5 minutes to reach the correct temperature. Stir the mixture as it's heating to prevent it from scorching on the bottom. Use your candy thermometer or an instant-read thermometer to determine whether the mixture has reached the right temperature. If you don't let it cook long enough, the curds won't separate from the whey. If you overcook it, the texture will be ruined.\n3. Slowly add the vinegar. Use one hand to stir constantly while the other hand slowly pours the vinegar into the heated milk and cream mixture. The vinegar will cause the curds to coagulate and separate from the whey. You'll see solid bits forming and floating to the top of the liquid. Keep stirring until all of the vinegar has been added. The curdling agent in this case is vinegar, but some people prefer to use other substances. Try substituting 3 tablespoons (44.4 ml) of lemon juice for a different flavor. For a more traditional touch, try using animal rennet as your coagulant. Mix 1 teaspoon of rennet with 1/4 cup of cold water, then stir it into the milk mixture.\n4. Let the mixture sit until it's thick. Wait about 10 - 20 minutes for the coagulant to go to work and cause the curds to separate from the whey. It's ready when the curds have floated to the top to form a thick layer, leaving the liquid whey underneath.\n5. Ladle the curds into the strainer. Scoop out the thick top layer of curds and ladle them over the cheesecloth-covered strainer. Keep ladling out the curds until all that's left in the saucepan is the whey. You can discard the whey at this point.\n6. Let the ricotta drain. Wait at least an hour for the last of the whey to drain from the ricotta through the cheesecloth into the bowl. It will take about half an hour for the ricotta to fully drain. Don't attempt to stir it or push it through the cheesecloth, as this will just push the curds into the cloth. If you'd like a creamier final product, stop draining the ricotta after 5 - 10 minutes. For a drier final product, wait an hour for it to drain.\n7. Spoon the ricotta into a bowl. The finished ricotta is now ready to use in your favorite recipe. It's delicious as part of a savory dish or a dessert. Ricotta will keep in the refrigerator for about a week.\n\n\n## Whey-based ricotta\n\n1. Save the whey from making cheese in a non-reactive pot. When you make homemade cheese, you'll have curds at the bottom of the pot, and you'll pour off the whey. Filter as many of the curd particles out as you can since they would otherwise form tough \"beads\" in the final ricotta. Cover the whey and let it sit for at least 12 hours at room temperature to develop sufficient acidity. Acidified whey acts as its own coagulant, making it unnecessary to add vinegar or lemon juice to separate the curds.\n2. Heat the acidified whey. Pour it into a saucepan and heat it while stirring, taking care to avoid sticking or burning. Heat until the temperature has risen to about 175 degrees Fahrenheit and a white appears on the surface. Continue heating and stirring until the temperature reaches 200 degrees Fahrenheit. Note that the foam will build up somewhat. Be careful. If it boils, it can boil over.\n3. Remove the whey from heat and wait for it to curdle. Cover it and allow it to cool undisturbed until comfortable to the touch. The curds will soon appear like clouds suspended in the whey, while the whey will be clear and yellowish green.\n4. Strain the ricotta. Do not stir up the curd. Instead, set up a receiving pot with a large strainer and a fine clean cloth on top. Ladle the curds into the cloth, leaving the whey in the saucepan. Discard the whey. Be sure to scoop out the curds gently. Because the curds are very fine and delicate, they can stop up the cloth easily. This will cause very slow draining if they are broken up.\n5. Drain the whey through the cloth. It can take 2-3 hours for the whey to completely drain. If you prefer, you can set the strainer in the refrigerator and let it drain overnight.\n6. Remove the ricotta from the cloth. Pack it into a container, cover it and store in the refrigerator. Use it soon after making. Ricotta will keep up to a week in the refrigerator. Alternatively, ricotta freezes very well.\n"}, 5] | |

"Members of the armed forces" of Russia who have "fallen into the power of [Ukraine]" are therefore protected by the provisions of the convention as prisoners of war as defined in the convention's fourth article.\n\nIt follows from this that the parenthetical commentary in the question's third bullet point is incorrect: refusing to call this "military action" a "war" does not in fact "unilaterally waive the protection of law of war for Russian forces."\n\nAs to the allegation in the second point, even a prisoner of war who is suspected of committing a war crime is entitled to the convention's protections. Any punishment for the war crime is to be imposed by due process of law. The fact that war crimes may have been committed by other elements of Russia's armed forces is even less of a justification to deny the convention's protections to prisoners who are not individually suspected of war crimes."}, 5] | |

In that case ```array_slice``` will duplicate that first large object, while ```array_keys``` will only grab the keys.\nPHP 7.3+\nPHP 7.3 onwards implements ```array_key_first()``` as well as ```array_key_last()```.

| [{"Instruction": "Explain how to find Bible verses by number or keywords.", "Response": "People quote the Bible in a variety of contexts. If you want to be able to look those quotes up, you’ll need to understand the way the Bible is organized. It’s also possible to look up quotes without knowing their location. Simply knowing a couple of words from a verse can be enough to help you locate it if you know how.\n\n## Look up a verse by number\n\n1. Identify the book of the verse. When Bible verses are listed, the first thing you’ll see is the name of a book. Use the table of contents in your Bible to locate that book within it. The table of contents is at the beginning of the Bible. Locate the name in the table of contents and turn to the page associated with the start of the book. The name of the book might be abbreviated or spelled out completely. Some books include:\n\t* Exodus (Ex)\n\t* Genesis (Gen)\n\t* Numbers (Num)\n2. Identify the chapter. After the book name, you’ll see two numbers. The first number is the chapter. For example, in “John 3:16”, “3” is the chapter number. Look at the verse and determine which chapter it is from in the book. Some people may cite Bible verse using abbreviations and Roman numerals. For example, Lev. xx:13 is the same as Leviticus, chapter 20, verse 13. Locate that chapter within the book. You may be able to find the location of that chapter in the table of contents. If not, you can thumb through the specific book until you see that chapter. As with other books, it should clearly say, “Chapter \\_\\_” at the beginning of each chapter. In addition, many versions clearly say, : at the top of each page indicating the first verse on that page. Some also note the last verse on the page.\n3. Identify the verse number. The second number after the book name is the verse number. This number should come after a colon (:). In the case of John 3:16, 16 would be the verse number. If you're looking up a longer passage, there may be two numbers, separated by a hyphen (-). For example, in John 3:16-18, you're looking for verses 16,17, and 18.\n4. Locate the verse within the chapter. Once you’ve found the chapter, go through it until you find the verse. The verses go in numerical order, just like chapters. There should be a small number at the beginning of each sentence or a small group of sentences. This is the verse number. If you're looking for multiple verses, such as John 3:16-18, 17 and 18 would follow directly after 16.\n\n\n## Look up a verse with a concordance\n\n1. Choose a concordance. A concordance is a book that lists every instance of a word’s appearance in the Bible. This is a great tool if you remember the verse, or part of the verse, but you don’t know which book or chapter it came from. Concordances can be found through religious retailers or online. Your church may also have one that you can borrow.\n2. Search for a word from the verse. Remember an important word from the verse. Look it up in the concordance the same way that you would look it up in a dictionary. Concordances are alphabetized. Choose a distinctive word that may have limited occurrences, such as “flood,” “mountain,” or “rubies.” If you choose something like “love” or “evil” you’re likely to find an enormous number of results.\n3. Search for other words if necessary. If you find too many results, or you don’t see the verse you’re looking for, try searching for another word. For example, if you remember the phrase, “love must be sincere” and you searched “love” but found too many results, try looking up, “sincere.”\n4. Locate the verse from the concordance list. The concordance will list all of the places where that word is found in the Bible. A complete concordance will give you some context so that you can be sure it’s the verse you’re looking for. Use the location that the concordance gives you (for example, Romans 12:9) to look up the complete verse and its context in your bible.\n5. Try another translation if necessary. Concordances are specific to translations. If you can’t find the verse you’re looking for, try a concordance for a different translation. For example, if your Bible translated a word to the English word “praise,\" but your concordance is for a Bible that translated that word as “worship,” it will be impossible to look up the verse.\n\n\n## Look up a verse online\n\n1. Search the verse number online. Choose a search engine, or go to a website dedicated to Bible study. Type the name of the book and the chapter and verse numbers into the search engine. Type the verse number in the generally accepted format if you can. For example, you'll get more accurate results if you type, \"John 3:16,\" than, \"Chapter 3 16 John.\"\n2. Remember what you can about the verse. Do you remember a certain phrase of the verse? Maybe you remember one or two words and the name of the book it came from. Even if you can’t remember very much, you can likely still look up the verse.\n3. Enter what you know into a search engine. Type in everything you can remember. You should also include the words “Bible” and “verse” to make sure that you get results that are relevant to your search. Your search terms may be something like, “Bible verse about wives in Psalms,” or “Bible verse chapter 7 desert.”\n4. Use a site designed for Bible searches. There are plenty of sites online that catalog Bible verses by subject or by book. You can use one of these websites to search for the verse. Type in a keyword or a subject. You may also be able to do an advanced search by book or chapter. These online tools can be great ways to find other verses that may be relevant to you or helpful in your studies or prayers.\n5. Search related words. If you can’t remember any exact words from the verse, or your search is not going well, search related words. For example, if you searched for “stars” and didn’t find anything, you could search for “night” or “sky” or “heavens” to see if the verse shows up. It’s possible you’re using a different translation or that you misremembered details about the verse.\n"}, 5] | |
| [{"Instruction": "Share tips for budget-friendly family travel.", "Response": "Traveling with kids can be a fun and exciting for the whole family. It can also be expensive, especially if you want to travel overseas or across the country. Between transportation, accommodations, and excursions, you may worry how you will be able to afford to travel with kids and ensure everyone has a good time. To save money when travelling with kids, focus on cheaper transportation options and affordable accommodations. You can also plan excursions and activities that will be affordable and fun for all.\n\n## Choose cheaper transportation options\n\n1. Drive rather than fly. To save money on transportation costs, consider planning an old fashioned road trip with the kids. The price of gas will likely be cheaper than paying for multiple plane tickets, especially if you have a large family. Try to travel with at least two people who can drive so you can drive in shifts, especially if the drive will be long. To keep the peace in the backseat while on the road trip, make sure you bring lots of snacks and games for the kids. Keep them occupied with music and singalongs in the car. This way, you can all travel in peace, cheaply.\n2. Use points to book cheaper flights. If you do want to fly to your destination as a family, be sure to use any points or reward miles that you have accumulated to book your plane tickets. Set up a rewards system for air travel through your credit card or through a rewards card for a specific airline. Always check to see if you can use points to reduce the cost of plane tickets or to get better deals on flights. You should also do your research on possible flight options so you can find the cheapest one. Compare flight prices online. Watch for flight deals and book them right away so you get a more affordable price.\n3. Consider taking the train. If train travel is an option, look into train prices to see if it will be affordable. You can often buy rail passes that you can use for many days at a time and there is usually cheaper family pricing. Train travel may be a good option if you are planning to travel across the country, such as within Europe or within a specific area in the U.S. Some train passes also cover admission to certain attractions and excursions in the area you are travelling to. This may be a good option if you want to also save money on attractions for the whole family during your trip.\n4. Take public transit as a family. Public transit, such as buses, light rail, and trams, are ideal if you want to save money when traveling with kids. Get a public transit pass as a family and use it to get around, especially if you are traveling to major cities or destinations. Often, public transit can be a great way to interact with the locals and see different areas from the comfort of your seat. Most public transit passes can be purchased by day or for multiple days. They are often $10 or less, depending on where you are travelling.\n\n\n## Select affordable accommodations\n\n1. Travel during the off-season or shoulder-season. Travelling during the off-season can make your travel expenses more affordable, especially transportation and accommodation costs. Going on your trip during the off-season, usually the fall months, will make hotels and other accommodations cheaper than during peak season. Consider booking your trip during the off-season or during shoulder-season, the time between peak and off-peak. For example, if you’re planning a trip to Walt Disney World, the shoulder-season is May and September, where crowds are thinner and accommodations are more affordable.\n2. Book a home share or a rental property. Finding cheap accommodations when you have kids can be a challenge, especially if you want a space larger than a hotel room. Consider renting a house through online rental property sites. Often, a home rental will have an affordable nightly rate or week by week rate. Having a home rental will also help you to also save money by cooking your own meals and not having to pay for parking, if the home rental has a parking spot already. A home share, where you share a home with other people or another family, can also be an affordable option. You may travel with family and friends and share a large home rental together to cut down on costs.\n3. Use hotel points to book a hotel. If you decide to stay in a hotel while travelling, use hotel points to make it more affordable. Collect points over time through your credit card or another rewards card and use the points to reduce your hotel rates. Try to book a hotel during off-season or shoulder-season so you get a more affordable rate. Sometimes booking a hotel during the week instead of the weekend can be a cheaper option. You can also try looking online for deals on hotels and book it before you leave on your trip. Often rates are cheaper online and booking in advance may save you money.\n4. Go for a family travel package that includes accommodations. If you are traveling to a destination that is known to be popular with kids and families, such as Disneyland, look for travel packages. Travel packages often include airfare and accommodations at a reduced rate. This could be a good way for you to save money and not have to worry about booking your own accommodations, as it is included in the package. If you are travelling to a tropical destination, such as Mexico, you may look into travel packages where you stay at a family friendly resort. Resort packages often include airfare and accommodations.\n5. See if you can stay with friends or family. To really save money on accommodations, see if you can all stay with friends or family who live near your destination. You may plan a trip to see friends or family members who have larger homes where you can all stay together. Or you may set up a blow up mattress that you can then use when staying with family or friends to make your accommodations very cheap.\n\n\n## Plan affordable excursions and activities\n\n1. Book excursions in advance to save money. Do your research and make a list of excursions you want to go to with the kids. Then, book these excursions in advance, if possible. Often, booking excursions in advance can get you a cheaper rate. It will also put less stress on you to figure out things to do once you arrive at your destination. You should also check for family pricing when booking excursions. Often, booking excursions as a group or a family can make them cheaper.\n2. Find free, fun activities for the kids. Excursions can be expensive, even with family pricing. To save money, look for free, fun activities for your kids. Research activities online in the area you are staying in, focusing on those that are free or very cheap. Come up with a fun, free activity for the kids to do while you are traveling. For example, you may book a free tour of the city you are staying in for you and the kids. Or you may take the kids to a play area at the resort you are staying in for free activities. You can also bring books and games from home with you on the trip so the kids have things to do while in the car or in the hotel.\n3. Bring snacks and light meals on excursions. To save money during excursions and activities, make sure you pack snacks and light meals. This way, if your kids get hungry, you have snacks on hand and can avoid eating out all the time. Buy snacks in bulk when you get to your destination. Prepare a few light meals that travel well and bring them when you are out for the day with the kids. For example, healthy snacks like nuts, sliced fruit, and granola bars are all good options. Light meals like sandwiches, mini yogurts, and sliced vegetables are also good for travel.\n"}, 4] | |

It allows companies to outsource work to people all over the world, and for people to find information and learn new things at incredible speeds.\nWithout the internet, all of these things would be much slower. It would take years for a new idea to spread around the world, for example, and companies would have to rely on people local to their business for all of their workforce.\nThe world would also be a much less connected place. It's easy to forget, as the internet has become such a huge part of our lives, that it's really only been around for a couple of decades.

Teens often want to join a gang because of certain issues such as racism, poverty, loneliness, and media influences. You can prevent your teen from joining a gang by education about the appeal of gangs for teens, talking and listening to your teen, and getting involved in your own community.\n\n## Educate yourself\n\n1. Learn the appeal of gangs. There are many reasons why a teen might join a gang. Learning the potential draw of gangs for teens can help you identify if your teen is at risk. Teens might seek out gangs for a feeling of belonging. If your teen feels like an outsider for any reason, he or she may seek out a gang for a sense of community. Peer pressure is also a major factor in teens joining gangs. If your teen has friends who are in a gang or associated with one, your teen may consider joining as well. Teens also don't always realize the danger of gangs. The idea of being part of a gang might be exciting, especially if your teen has been exposed to video games and other media that glorifies gang violence. If your teen has an underlying mental illness, such as a personality disorder, he or she might seek thrills through joining a gang.\n2. Investigate gang activity in your area. Location is a big risk factor when it comes to your teen joining a gang. Be aware of any gang activity in your area so you know what your teen might be exposed to at school or in the community. You can research gang activity in your area by browsing police reports and police data online. Most areas have a police blotter website where you can enter your zip code and see of any recent arrests or disturbances in your area. Talk to officials at your teen's school. Principals and superintendents should be aware if there is any gang activity occurring in their jurisdiction. Make an appointment with an official at the school and ask him or her about gang activity. Many people feel certain locations make them immune to gangs. If you live in the suburbs, for example, you might think your teen is immune to gang violence. However, in a lot of big cities gangs eventually move into the suburbs. In the Chicago suburb Evanston, for example, gang activity has been on the rise in the last few years. Be vigilant about potential gang activity regardless of your location.\n3. Familiarize yourself with the warning signs your teen is involved with a gang. Make sure you know the warnings signs regarding gang activity in teens. You should be concerned if your teen is displaying any of the following signs:\n\t* Wearing a certain color or color scheme suddenly\n\t* An increased interest in gangs, gangster music, and gangster movies\n\t* Bragging about having friends in gangs\n\t* Coming home with expensive items\n\t* Using hand gestures and signs to communicate with friends\n\t* Aggressive or withdrawn behavior\n\n\n## Work with your teen\n\n1. Talk to your teen about gangs. Education is key to keeping your teen from joining a gang. Take time to sit down and talk to your teen about the dangers of gangs. Be as frank as possible when discussing gangs with your teens. Explain that, short term, gang activity can lead to trouble with police, trouble with school, and poor relationships with family members. Longterm, make sure your teen knows gang activity can prevent them having access to education and employment options, time in jail, and a risk to their personal safety and the personal safety of their family and friends. Listen as well. Your teen may be compelled to argue or even disregard what you're saying. Try to understand why your teen is resisting. Is he or she being intimidated by a gang? Is a person your teen looks up to in a gang? Understanding the reasons gang membership is appealing to teens can help you better address the problem.\n2. Keep your teen engaged in other activities. Teens often join gangs for a sense of community or for some excitement. Keeping your teen as engaged in other activities as possible can lessen the draw of gangs. Encourage your teen to engage in activities that appeal to his or her interest. Is your teen always sketching or drawing? Enroll him or her in art classes. Is your teen athletic? Encourage him or her to join a school sports team. Is your teen interested in music? Invest in a piano, guitar, or other musical instrument. Push your teen to find an after school job. While some teens might resist the notion of working, emphasize how building a work ethic can help later on. Talk about what your teen could do with all the extra spending money. Allow your teen to have friends over at your house. You want your teen to feel most comfortable at home, where it's safe. This also gives you an opportunity to get to know your teen and his or her peers. You can encourage wholesome activities, like board games and age appropriate movies, over the kinds of activities that might land your teen in trouble.\n3. Learn how to best communicate with a teen. Communicating with teenager can be difficult. Most teens feel an increased need for autonomy and independence, which means they may pull away and rebel against you. However, learning the means to effectively communicate with a teen can help. Always listen without judgment. If your teen is willing to share something with you, let him or her. Try to stay calm and listen, even if your concerned by what your teen is saying. Remember, as a parent you're better off hearing bad news than not hearing it. Being reactionary and harsh can discourage your teen from reaching out when in need. Respect your teen's sense of privacy and autonomy. Unless you suspect a serious problem, allow your teen his or her own space. Let them have a bedroom to themselves. Do not always ask who your teen is calling or texting on the phone. Do not touch your teen's belonging without permission. Schedule times to talk. You do not need to schedule a weekly conversation, but having a family dinner night or board game night gives your teen the opportunity to share. Strive to keep communication open and keep yourself available when your teen is in need.\n4. Identify positive role models for your teen. Teens often join gangs because they feel lost. Lacking positive role models, a teen might turn to the allure of a gang. Identify positive roll models for your teen. Get your teen involved in the community. Encourage him or her to volunteer. Take him or her to church, town hall meetings, and other places and meetings you attend. Teach your teen about people you admire. This can be someone you know personally, like your great-grandmother who supported her family during the Great Depression. It can also be a public figure, like a politician or activist. Showing your teen what you believe admirable qualities constitute can lessen the appeal of gang members.\n\n\n## Improve your community\n\n1. Remove gang related graffiti. Graffiti is often a way for gangs to advertise and recruit new members. If you notice new or unusual graffiti in your area, google the images to see if they're gang affiliated. If they are, talk to the local police about having them removed as soon as possible. Depending on regulations in your area, you may be able to remove the images yourself or schedule a community cleanup. Stop by the local courthouse and ask what your options are in terms of arranging a cleanup.\n2. Team up with other parents. The phrase \"It takes a village to raise a child\" exists for a reason. You cannot do this alone. Work with other parents to build a stronger community and to keep out gangs. Schedule a meeting with other parents in town to discuss gang activity in your area. Brainstorm ideas about how to keep your teens out of gangs. Working together, you and other parents can create regular community events and activities for teens to engage in in order to discourage them from joining gangs. You can also go, as a group, to a PTA to raise any concerns you have about gang activity in the school system. Look into starting a neighborhood watch to keep on the lookout for gang activity.\n3. Take political action. In order to address gang activity, political action may be necessary. Increasing law enforcement presence in your are and providing community outreach to at-risk teens may be needed in your area. Start letter writing and phone campaigns to local members of Congress. Explain why your area needs help addressing gang violence and gang activity. Demand community outreach in your area. Raise awareness. Buy an ad on the local radio. Hand out pamphlets at community centers, schools, churches, grocery stores, and other areas. A single call to local police about gang activity has little effect. A collective group effort is necessary to stomping out gang activity in your area. Make sure other parents on board with talking to the police together.\n"}, 4] | |

Ask your doctor to recommend the best physical therapist for your condition. Many people have to decide based on who their insurance will cover; however, some physical therapists specialize in certain conditions and can offer expertise that an insurance-covered physical therapist cannot. Choose based on what you can afford and how important your timely recovery is.\n2. Call your insurance to ask how many visits are covered. Many insurance plans have caps on physical therapy treatments, from 10 to 35. After severe injuries, you may be able to apply to the insurance company for more treatments, if they are absolutely necessary.\n3. Ask the physical therapy office if you can have a discounted rate, if you are paying out of pocket. Insurance companies often get a discounted rate, so they may afford you the same price. Ask the physical therapist directly, rather than the secretary, because it is the physical therapist that is agreeing to alter their wages.\n\n\n## Physical therapy sessions\n\n1. Have a positive attitude toward physical therapy. Will power and optimism during a recovery are almost as important as doctor's care. Your commitment to the exercises will have a direct correlation to the swiftness and completeness of your recovery.\n2. Wear athletic shoes and loose-fitting, flexible clothing to all physical therapy sessions. If you have to go to your session straight from work, then keep spare exercise clothing in your bag or car. This type of clothing allows you the full range of motion in your exercises and keeps your regular clothes clear of analgesic creams or massage oils.\n3. Drink plenty of water while you are exercising. Although this is a general rule, it is even more important when you are healing from an injury. Stay hydrated throughout the day and bring a water bottle to your session.\n4. Show up early to each appointment. Your physical therapist may allow you to warm up before the session, on a machine or by stretching. This also makes certain that you are never late, because you will be charged for the session from the moment your appointment time arrives. Make sure to be 15 minutes early for your first appointment. You will need to fill out insurance and health forms. Bring a list of your medications and other current treatments.\n5. Discuss your goals with your physical therapist at your first meeting. Pain and injury are different for everyone, so you must make it clear whether you want to return to work, get rid of pain, walk without weight supports or run a marathon. Tell the physical therapist how many sessions you can afford, so the plan can be adjusted for what you will do during your sessions and what you can continue at home. Remember that this may need to be adjusted on the future, based on your progress. In most cases, the harder you work doing prescribed exercises at home, the fewer office sessions you will need to have.\n6. Ask your physical therapist to give you a list of prescribed exercises, with diagrams. They should establish what and when you should be doing each exercise, so that you are clear about your \"homework.\" Ask the physical therapist to show you each exercise as well as having you do repetitions in the office.\n7. Tell your physical therapist whenever something is painful. Mistakes can be made if you do not communicate properly about your pain levels. The physical therapist can also tell you what pain is natural to the healing process and what is unnatural, allowing the exercises to be adjusted.\n8. Ask to be treated by the same physical therapist every time. This provides consistency, familiarity and a greater chance that you will be able to accomplish your goals.\n9. Ask plenty of questions. You must be proactive about your treatment. If you don't understand why you are doing something or how you should do something, you are more likely to refrain from the exercise and fail to progress.\n10. Report your progress at the beginning of each physical therapy session. Make sure you tell your therapist any new pain or problems, as well as your positive progress. They will usually write this on your chart to ensure you won't have complications from the regime.\n11. Leave your cell phone and personal problems at the door when you go to physical therapy. You must use this valuable time to focus on health and your body. You may need to learn to recognize your body's warning signs, which is hard to do when you are distracted.\n\n\n## Physical therapy at home\n\n1. Create a schedule to do your physical therapy exercises at home. Do not leave it up to chance whether you have the time or not. They are as important as doctor-prescribed medicine and should be treated as a priority during your day.\n2. Set aside a space to do physical therapy. Keep a corner of your home ready with a yoga mat or exercise ball, so that you can do a few repetitions when you have some free time. This will help you get into the mentality of exercise as a lifestyle choice.\n3. Take the prescribed therapy exercises seriously. If you are advised to do them once per day, do them every day, and if you are asked to do them 3 times per day, do them 3 times per day. Frequent exercises are usually prescribed when there is a limited time for you to regain your mobility during the healing process, and they should be treated with gravity.\n4. Progress to more repetitions or sets as you get stronger. Many physical therapists will tell you to add 5 repetitions or 1 more set when the exercise becomes easy. You may also be asked to add more weight to your exercises.\n5. Ask the physical therapist for an appropriate regimen to continue after you no longer attend sessions. They should be able to adjust an exercise regime according to your particular health problems. Establish goals that you should reach 3 months, 6 months and a year into the future.\n"}, 4] | |

Some great apps and online programs include Rosetta Stone, Duolingo, Babbel, etc. It’s also a good idea to take language classes in person or online, where you can ask your teacher questions and practice speaking with your teacher and classmates.\n\nHere are some other tips for learning a new language:\n\n* Set your language goals. When you’re first figuring out how to learn a language, you should focus on some short-, medium- and long-term goals. These can help to give structure and direction to your learning. Adding timescales to your language-learning goals can help to keep you on track and motivated. \n\n* Learn common vocabulary. This can help to quickly build your understanding in a day-to-day setting, allowing you to have and follow basic conversations. \n\n* Find a style that works for you. There are many different tools, techniques, and styles you can use when you’re learning a language. Whether it’s using flashcards, grammar translations, spaced repetition, immersive learning or any other approach, you have plenty of options. Figuring out the right combination of techniques can help you progress at a rate you’re happy with. You’ll find all kinds of apps, websites, textbooks, and other materials out there that help with different methods. \n\n* Practice speaking. A crucial part of learning a language is being able to recognise, understand and reproduce sounds. You don’t have to necessarily go out and start chatting with native speakers right away (although this can certainly help). However, talking to yourself, practicing your vocabulary out loud, and even recording yourself speaking your new language can help to build your confidence. \n\n* Connect with a native speaker. Communicating with new people in your target language is often intimidating. You might be scared to make mistakes or feel that your current level isn’t good enough. However, practicing with a native speaker can help you quickly improve your language skills. \n\n* Engage with the culture. Language often evolves in line with the culture of the groups who speak it. Therefore, to really master a language, you’ll want to make sure you’re also familiar with the cultural context that goes with it. \n\nI hope this helps!"}, 4] | |

Same principle here.\nIf the boss is that much better than you and you know it, he probably knows it too. He isn't expecting any great feats of programming rock-stardom out of you. Since this is your first job, he most likely hired you because he saw the potential to become a good coder in you. So if you really want to impress him, learn. Learn the language, learn the system you're working on, learn the ins and outs and dark corners. Focus on learning correct principles, learning them well and learning them quickly, in that order.\nAnd remember that part of learning is copying knowledge that other people already have. Don't be afraid to ask questions, either of your coworkers or on StackOverflow, or research things on Google.

There is ```shlex.quote``` for Unix-like systems, but nothing really standard for Windows. Maybe see also python, windows : parsing command lines with shlex\n\n* MacOS/X: ```os.system(\"open \" + shlex.quote(filename))```\n* Windows: ```os.system(\"start \" + filename)``` where properly speaking ```filename``` should be escaped, too.\n\n* You can also call them via ```subprocess``` module, but...\nFor Python 2.7 and newer, simply use\n```subprocess.check_call(['open', filename])\n```\nIn Python 3.5+ you can equivalently use the slightly more complex but also somewhat more versatile\n```subprocess.run(['open', filename], check=True)\n```\nIf you need to be compatible all the way back to Python 2.4, you can use ```subprocess.call()``` and implement your own error checking:\n```try:\n retcode = subprocess.call(\"open \" + filename, shell=True)\n if retcode < 0:\n print >>sys.stderr, \"Child was terminated by signal\", -retcode\n else:\n print >>sys.stderr, \"Child returned\", retcode\nexcept OSError, e:\n print >>sys.stderr, \"Execution failed:\", e\n```\nNow, what are the advantages of using ```subprocess```?\n\n* Security: In theory, this is more secure, but in fact we're needing to execute a command line one way or the other; in either environment, we need the environment and services to interpret, get paths, and so forth. In neither case are we executing arbitrary text, so it doesn't have an inherent \"but you can type ```'filename ; rm -rf /'```\" problem, and if the file name can be corrupted, using ```subprocess.call``` gives us little additional protection.\n* Error handling: It doesn't actually give us any more error detection, we're still depending on the ```retcode``` in either case; but the behavior to explicitly raise an exception in the case of an error will certainly help you notice if there is a failure (though in some scenarios, a traceback might not at all be more helpful than simply ignoring the error).\n* Spawns a (non-blocking) subprocess: We don't need to wait for the child process, since we're by problem statement starting a separate process.\n\nTo the objection \"But ```subprocess``` is preferred.\" However, ```os.system()``` is not deprecated, and it's in some sense the simplest tool for this particular job. Conclusion: using ```os.system()``` is therefore also a correct answer.\nA marked disadvantage is that the Windows ```start``` command requires you to pass in ```shell=True``` which negates most of the benefits of using ```subprocess```.\n"}, 4] | |

Get a water bowl that is the right size for your dog. Make sure your dog’s water bowl is the right size for them, as a bowl that is too big or too small will limit their access to water. Check that the water bowl is made for a small, medium, or large dog. Get the size that will make it easy for your pup to bend down and drink from the bowl. For example, tall, narrow bowls are ideal for dogs with long ears, such as Bassets and Spaniels. This can help to keep their ears out of the bowl, which can reduce the risk of ear infections. Smaller dogs do well with a water bowl that is low and shallow, as this will make it easier for them to drink from the bowl. A bowl that is big and wide is ideal for medium to large dogs.\n2. Buy a weighted water bowl. A weighted water bowl will have a heavier bottom, making them less likely to tip over. This may be a good investment if you are worried about your dog tipping over their water bowl or moving the bowl around and spilling the water while they drink. Look for weighted water bowls online or at your local pet store. Test the water bowl before you give it to your dog to use. Fill it with water and tap or try to tip one side of the bowl. A weighted water bowl should make it harder to do this.\n3. Invest in a water fountain. Larger dogs and dogs who are picky about their water may benefit from a water fountain. Most water fountains will filter and recirculate the water so it is fresh and tastes delicious to your dog. You can buy water fountains online or at your local pet store.\n\n\n## Hydrate your dog at home\n\n1. Fill your dog’s water bowl daily. Make sure you keep your dog’s water bowl filled with fresh water on a daily basis. Fill it up first thing in the morning when you give your dog their breakfast. Then, check their water bowl throughout the day to make sure it is full. Fill it up again at dinner time, if it needs refilling. Make sure you toss out any old water from the previous day before you fill it up with fresh water. This will ensure the water tastes good to your dog and is free of bacteria.\n2. Clean their water bowl regularly. Bacteria can end up sitting on the rim of the water bowl and in any water still in the water bowl. Get in the habit of cleaning your dog’s water bowl on a daily basis. Use soap and water to remove any grime or dirt in the bowl or on the rim. Dry the bowl well before you fill it up with fresh water and set it down for your pup. For example, you may clean the bowl first thing in the morning before filling it up with fresh water. This way, it will stay clean for the rest of the day until you clean it again the following morning.\n3. Place water bowls for your dog throughout your home. If your dog likes to roam through your home, make sure you have water sources located throughout the space for them. Put water bowls on each floor of your home. Set up water fountains in several spots in your house so your dog always has access to fresh water. Doing this will ensure your dog never gets dehydrated. Make sure you clean all of your dog’s water sources in your home on a daily basis. This will ensure they do not get dirty or contract any bacteria.\n4. Keep the toilet seat down in your home. Prevent your dog from drinking from the toilet bowl by keeping the seat down at all times. The water in your toilet bowl likely contains bacteria and other pathogens that are harmful to dogs. Keeping the seat down will make it difficult for your dog to access the toilet bowl water. It will also encourage them to drink the fresh, clean water from their water bowl instead. If your dog really enjoys drinking from the toilet, consider purchasing a ceramic bowl for them that will mimic the type of “bowl” your toilet is.\n5. Switch your dog to wet food. To encourage your dog to stay hydrated, consider switching from dry dog food to wet dog food. Wet dog food contains more water and can help your dog stay hydrated. Add water to their wet food at a 1:1 ratio to help your dog drink more water. You can also try giving your dog two wet food meals and one dry food meal a day. Wet dog food can be more expensive than dry food and requires more preparation time, so this may be a good option if you’re short on time and money. If your dog will eat all of their dry food at one time, you can try adding water to the dry food. Many dogs will consume all of the dog food as well as the water.\n\n\n## Hydrate your dog on the go\n\n1. Bring bottled water on walks or long trips. Dogs can often get dehydrated when they are out for a long walk or running around outside during a play session. Long car trips can also make your dog thirsty, especially if it is a hot day. Pack bottled water or water jugs and your dog’s water bowl so you can provide fresh water for them on the go. Some dogs can be trained to drink from a squirt bottle. Try to get your dog used to drinking from a squirt bottle so you can bring it with you when you go on a walk or to a dog park. This will make it easier for you to squirt water into your dog’s mouth if they start to get dehydrated. You can also purchase a portable, collapsible dog bowl to take with you on the go.\n2. Give your dog ice cubes as treats. Ice cubes are often a fun treat for dogs and can help them stay hydrated. Use ice cubes as a reward when your dog does a trick or follows an obedience command. Pack a cooler of ice cubes on a long trips and give them to your dog periodically to ensure they stay hydrated. To make the ice cubes more appetizing, you can try putting a dog treat in water in the ice cube tray and freeze it overnight. This way, your dog can lick the water, working their way to the treat inside the ice cube.\n3. Do not keep your dog tied up outside. Try not to keep your dog chained or tied up outside, especially on hot days. Dogs can end up wrapping their chain or leash around poles or trees, make it impossible for them to access their water bowls. Do not leave your dog tied up unattended for prolonged periods of time. If you do need to keep your dog contained, put them in their crate or kennel with access to a water bottle or a water bowl. This way, they will still be able to access fresh water.\n"}, 4] | |

Yes, your oven was probably set way higher, but the water content in your filling prevents it from getting hotter than boiling water. Commercial canning is done in the vicinity of 120-130°C, which is possible because the cans are cooked under pressure. So unlike in a can, most pathogens were destroyed, but not necessarily all of them. For human consumption, that’s perfectly fine as long as the remaining ones don’t get the time-temperature combo to regrow.\nSecond, a bread dough may be dense (although the aim is usually something different), but by no means airtight. Interestingly, wrapping meat in dense dough was used as preservation method in medieval times - the “ancestor” of today’s pork pies and pastries. But while the hard flour crust (not intended to be eaten originally) did form a protective layer and usually extended the shelf life more or less, it was by no means food safe judged by modern standards - although some pies were stored for months. But your fluffy buns are truly not a protective layer. Which means you should refrigerate your buns, but also that you get to enjoy the whole dish."}, 4] | |
| [{"Instruction": "Explain why dictators restrict citizens from traveling abroad.", "Response": "People are resources, dictators (and oppressive regimes in general) don't want them to defect to other countries because they want them working for their regime. Some of them are going to be people that the regime has put their resources into, like scientists and doctors, but even laborers are valuable for actually gathering and assembling the resources the regime needs. Additionally, the regime especially does not want people with access to sensitive information to defect to their enemies. That isn't just spies and soldiers, there are plenty of \"regular\" government positions that require access to something the regime would not want falling into enemy hands, like economic data that could be used for propaganda. Obviously this is true of any country, and even in democracies with strong human rights records, people with access to classified information are usually required to submit to strict scrutiny of their international travel. Given that they aren't concerned with human rights, dictatorships can take the easier option of restricting travel to any citizens.\nHowever, defection is really a piece of a bigger issue - oppressive regimes maintain their rule in part by controlling information. Here's an interesting article that talks about how dictatorships keep power. Jerrold Post, director of the political psychology program at George Washington University, is referenced:\n\n Post said that in both Iraq and North Korea, dictators tightly controlled the flow of information. That control was upended in the past two years during the \"Arab spring\" revolts that swept away despots in Tunisia, Egypt, Libya and some of the Gulf states, revolts that were encouraged in large part by information spread by cell phones and social media. \n\nNorth Korea is probably the most extreme example of information control (according to Reporters without Borders, they are dead last in Press Freedom in the world), but this can be seen in other oppressive regimes - for example, China attempts to limit access to \"wrong\" information via its Great Firewall. This is thrown out the window if citizens go somewhere with free media and realize they are being lied to. Traveling can be the cause of their dissension, rather than a symptom.\nKnown dissidents may also be restricted from traveling so that they can not coordinate with foreign countries or anti-dictatorship organizations, and to prevent them from smuggling contraband or evidence of the regime's misinformation back into the country. Regimes can control the information originating in their country, but once someone is outside their borders the regime cannot control who they speak with."}, 4] | |
| [{"Instruction": "How to prevent bone loss as you age", "Response": "Your bones reach their peak bone mass level when you are in your 30s, and then bone mass starts to decline. For women approaching menopause, bone loss is an even bigger concern because bone cell regeneration begins to slow around this time. However, there are steps that you can take to prevent bone loss, including avoiding certain foods, eating calcium-rich foods, and taking other preventative measures like exercising and having a bone mineral density test. Learn how to eat to get the right blend of vitamins and minerals and reduce your chances of losing bone mass as you age.\n\n## Reduce bone loss with food choices\n\n1. Steer clear of soft drinks. Many carbonated beverages contain phosphoric acid, which can affect your body’s ability to absorb calcium. Phosphoric acid causes you to lose calcium when you urinate. To reduce the calcium that you lose from drinking sodas, limit or avoid sodas altogether. Try drinking beverages that do not contain phosphoric acid, such as club soda, water, herbal teas, black or green teas, or fortified orange juice.\n2. Watch your sodium intake. Sodium is a major cause of calcium loss and a high-sodium diet has been linked with developing osteoporosis. The more sodium you have in your diet, the more calcium you will need to get in order to make up for it. Try to limit your sodium intake to 2,300 mg per day to help reduce your calcium loss.\n3. Limit caffeine. Caffeine also reduces your body’s ability to absorb calcium, so it is important to keep your caffeine intake under control to prevent low calcium levels. If you want to eliminate bone loss from caffeine intake, you can switch to decaf or choose beverages that are naturally caffeine free, such as peppermint or chamomile tea. Try not to exceed 300 milligrams of caffeine per day. That’s about the equivalent of 2 8 fl oz (240 mL) cups of coffee. Try switching to tea. It is lower in caffeine than coffee and has been shown to protect bones from calcium loss.\n4. Cook from scratch whenever possible. Food that is processed lacks trace minerals that have a protective effect on bones. To make sure that you are getting the most nutrient-dense diet possible, cook your meals from scratch whenever you can. Try choosing fresh instead of frozen or canned vegetables, make your own bread, cook whole grains such as brown rice, and avoid pre-packaged prepared foods.\n5. Choose quality proteins. Since bones are made up of mostly protein, getting enough of the right kind of protein is an important part of maintaining bone density. Try to avoid red meat as much as possible since it tends to be more acidic and may reduce the amount of calcium that your body can absorb. Make sure that you include enough quality protein sources for your size and gender to reduce bone loss. Good sources of protein include:\n\t* Eggs\n\t* Dairy products like milk, cheese, and yogurt\n\t* Poultry, such as chicken and turkey\n\t* Seafood, such as salmon, halibut, and shrimp\n6. Skip the soy unless your doctor recommends it. Soy has been found to have adverse effects on the absorption of calcium as well, so it is best to avoid eating too much soy. Even if a soy product is fortified with calcium, your body won’t absorb the calcium well. If you rely on soy as a primary source of protein, then it is a good idea to take a calcium supplement for extra protection. On the other hand, some studies have shown that eating soy-based foods may improve bone health overall and reduce your risk of developing osteoporosis. Talk to your doctor or a dietitian about whether you should incorporate soy into your diet.\n7. Eat sources of Vitamin K. There are 2 forms of vitamin K: K1(phylloquinone) and K2 (menaquinone). The combination is sometimes called MK7 in commercial supplement products. You should aim for about 250-1000 mcg of K1 and 45-180 mcg of K2 per day. Eat a good source of vitamin K 2 to 3 times a week to get these amounts or take a supplement. Natural food sources of vitamin K include:\n\t* Sauerkraut\n\t* Aged cheese\n\t* Natto (a soy product)\n\t* Kimchee (fermented Korean cabbage)\n\t* Beef liver\n\t* Green tea\n\t* Turnip greens\n\t* Broccoli\n\t* Kale\n\t* Spinach\n\t* Cabbage\n\t* Asparagus\n\t* Dark green lettuce\n\n\n## Get more calcium\n\n1. Drink and eat low-fat dairy products. Dairy products provide a significant amount of calcium, so make sure that you include 2 to 3 servings of dairy per day in order to get enough calcium. Since dairy products are naturally high in fat, it is a good idea to seek out low-fat and fat free dairy products. Milk has long been known as a good source of calcium and it should be a staple in your diet if you are trying to avoid bone loss. Drink 2 to 3 glasses of low-fat or non-fat milk per day. Cheese and yogurt are also good sources calcium, although they do not contain as much calcium as milk does. Choose low-fat cheese and yogurt to reduce your intake of unhealthy fats.\n2. Include canned sardines and salmon in your diet. Certain canned fish, such as sardines and salmon, are also good sources of calcium, as long as you eat the bones. The fish bones tend to be softer in canned fish, so they are edible. When eaten fresh, certain types of fish are good sources of vitamin D as well. For example, salmon, tuna, and mackerel are good sources of vitamin D.\n3. Have some leafy greens. Leafy greens such as kale, Chinese cabbage, turnip greens, and collard greens are also good sources of calcium. Try sautéing some greens, adding them to a soup, or using them in place of your usual salad greens.\n4. Choose calcium-fortified orange juice. Drinking orange juice that has been fortified with calcium may also help you to prevent bone loss. Choose fortified orange juice as well as other types of fortified beverages to get a little more calcium in your diet.\n5. Take a supplement that contains calcium, magnesium, and vitamin D. To ensure that you are getting enough calcium in your diet every day, take a supplement that contains calcium, magnesium, and vitamin D. To help prevent bone loss, it is crucial to get enough magnesium and vitamin D along with calcium. It may be easier for your body to absorb calcium if you take it in smaller doses with meals (500 mg at a time). However, it is possible to get too much calcium, so talk to your doctor about the best amount and type of calcium supplement for you.\n\n\n## Take other step\n\n1. Get regular exercise. Performing regular weight-bearing exercise is a good way to build bone mass and prevent bone loss as well. Weight-bearing exercises include walking, dancing, jogging, and dancing. Non-weight bearing exercises include biking and swimming. Try going for a 30-minute walk most days of the week to get in some weigh-bearing exercise and help prevent bone loss.\n2. Spend time in the sun. The best way to get your daily dose of vitamin D is to spend about 15–20 minutes in the sun without sunblock every day. Exposure to the sun allows your body to produce its own vitamin D. Since this may not always be possible, especially during the winter in some places, supplementing with vitamin D is still advised.\n3. Get tested for osteoporosis. One serious problem with osteoporosis is that it can be symptomless. Many women will not know that they have osteoporosis until after a bone fracture. That is why it is a good idea to have a bone mineral density (BMD) test if you are at risk of osteoporosis. This test is often called a DEXA (Dual-Energy X-ray Absorptiometry) and can help your healthcare professional to diagnose osteoporosis. Women over the age of 65 are at higher risk of developing osteoporosis, but other women under the age of 65 may be affected as well. Ask your doctor about getting a DEXA scan if you have:\n\t* Broken a bone from doing something that should not have caused a broken bone, like falling from a standing position\n\t* A chronic condition such as rheumatoid arthritis, kidney disease, or an eating disorder\n\t* Early onset menopause\n\t* Undergone hormone treatments, such as for prostate or breast cancer\n\t* Lost a noticeable amount of height\n\t* A history of smoking or currently smoke\n\t* Family members who have had osteoporosis\n\t* Been taking certain medications, such as corticosteroid or thyroid hormone replacement medications\n\t* A tendency to drink 3 or more alcoholic beverages most days\n4. Learn your T-score and Z-score. The results of a DEXA scan are known as a “T-score” and a “Z-score,” though for most people, the T-score is most important. In both the T-scores and the Z-scores, a negative number indicates that your bones are thinner or more porous than they should be. A higher negative number means that you have a higher risk of a bone fracture. If your T-score is between 0 and -1.0, this is considered normal. A T-score between -1 and -2.5 indicates that you have early osteoporosis, known as osteopenia. A T-score of less than -2.5 indicates osteoporosis.\n\n\n## When to seek medical treatment\n\n1. See your doctor if you have symptoms of osteoporosis. Osteoporosis doesn’t always have symptoms, especially in its early stages. However, there are some signs and symptoms you can look out for if you’re going through menopause or have other risk factors for osteoporosis. Call your doctor right away if:You’ve recently fractured a bone, especially if the fracture happened more easily than expected\n\t* You are experiencing frequent back pain\n\t* You notice your posture becoming stooped\n\t* You’re not as tall as you used to be\n2. Ask your doctor about medical treatment or prevention options. Diet and lifestyle changes can help prevent or slow bone loss associated with menopause, but there are also medical options. If you’re going through menopause and are at risk of developing osteoporosis, your doctor may recommend taking hormone therapy, vitamin D supplements, or osteoporosis medications. Common osteoporosis medications include:Bisphosphonates, a type of medication that prevents bone loss\n\t* Injected medications that can prevent bone loss and even stimulate new bone growth, such as denosumab (Prolia) and teriparatide (Forteo)\n3. Talk to your doctor before making major diet or lifestyle changes. Your individual diet and exercise needs depend on a lot of factors, including your age, weight, and overall health. Before drastically changing your diet or starting a new exercise regimen, talk to your doctor about what’s safe and healthy for you. For example, if you already have osteoporosis or a related condition, such as osteoarthritis, your doctor may advise avoiding certain types of exercise. Talk to them about doing forms of exercise that are easy on your bones and joints, such as low-impact aerobics, swimming, biking, or fast walking. Always let your doctor know before you take any dietary supplements, since these could interfere with medications or supplements you are already taking, or affect any medical conditions you might have.\n"}, 4] | |
| [{"Instruction": "Explain how sprite flipping works in retro hardware.", "Response": "For each sprite displayed on a scanline, the hardware fetches two bytes from memory, and then clocks the pixels out one by one. The sprite is eight pixels wide, and each pixel is two bits, which is why it's two memory accesses per sprite per scanline. You can imagine that this arrangement just needs a couple of shift registers to clock the pixels out.\n\nNow, flipping the sprite about its vertical axis is easy: you just clock the pixels out in reverse order! Similarly, flipping the sprite about its horizontal axis is also easy: You just fetch the bitmap from memory in reverse order. Rotating by 180° of course is the same as flipping both horizontally and vertically.\n\nBut if you wanted to rotate the sprite 90° or 270°, that's much harder. That's because the hardware would need to get one pixel from each pair of bytes, which means fetching 16 bytes from memory instead of just two. There is not enough time on this slow hardware to do that. Incidentally, this is also where the maximum number of sprites per scanline limitation comes from.\n\nIt's a similar story on the Commodore 64, the Atari 2600, and many others: These platforms can do some simple 2D manipulations on sprites like stretching and sometimes flipping like you've seen, but never rotations."}, 5] | |
| [{"Instruction": "How to fold and store polo shirts properly?", "Response": "Polo shirts are great because you can wear them almost anywhere. To keep your polo shirts looking good, make sure to fold them correctly. Start by placing them on a firm, flat surface. Fold in the sides and sleeves before bringing the bottom seam right below the collar. Store your polos by rolling them into tight bundles or stacking them on top of one another in a moth-free setting.\n\n## Fold your polo in the traditional way\n\n1. Lay the shirt on a flat surface. Find a flat, smooth surface, like a laundry table. Position the shirt on the middle of the surface with the button-side (front) facing down. Stretch out the sleeves to each side. Make sure that the edges of the shirt do not fall off the sides of the surface. Fully button up the shirt from top to bottom. Button up the cuffs as well.\n2. Fold the sleeves back. Grab each sleeve and fold it to the middle of the back of the shirt (the button-free side that is currently facing upwards). Try to keep the each sleeve horizontal. This will make the cuffs overlap in the middle center of the shirt. As you adjust the sleeves, be careful not to pull the side seams of the shirt towards the back. You are just folding the sleeves in at this point, not the core of the shirt. If you have a short-sleeved polo, you will still fold the sleeves toward the middle of the back of the shirt. However, the sleeves will not overlap in the middle.\n3. Smooth the shirt out with your hands. The key to folding any shirt, including polo style, is to run your hands over the fabric after every fold. This helps to smooth out the wrinkles and to ensure tight, secure folds. If you come upon a heavy wrinkle in the fabric, make minor adjustments until it disappears.\n4. Fold in the sides of the shirt. With the front of the shirt still facing down, gently grasp one side of the shirt with both hands. Fold this side inwards until it touches the middle of the shirt’s back. Do the same thing with the other side. If you do this correctly, you should see a “V” at the top back of the shirt right below the collar. If you have a short-sleeved polo, this fold will help to keep your sleeves in place moving forward. Make sure to hold your sleeves in place as you complete this step or they may move around as you lift the sides to fold inwards.\n5. Fold the shirt in half. Keep the button-side of the shirt facing down. Grasp the bottom edge of the polo shirt. Fold the edge upwards until the shirt is essentially at half of the full length. When you are finished you want the bottom edge of the shirt to rest right at the lower edge of the collar.\n6. Do an extra fold depending on the shirt’s length. If your shirt is extra large or extra long, then a single bottom fold may not be enough. You may need to divide the length of the shirt into thirds or fourths, adding in 1 or 2 additional folds.\n7. Flip and store. Grab your folded shirt and flip it over. The collar should now face upwards. This is a great way to store your polo shirts, as it keeps the collars and sleeves crisp. It’s even safe to stack multiple shirts on top of one another for storage, as the pressure will keep any wrinkles at bay.\n\n\n## Roll your polo shirt\n\n1. Save space by rolling. If you have a small closet or just a single drawer to use, then rolling is good option. Many people also prefer to roll all of their clothes when packing suitcases, as it makes it easy to select outfits quickly. The downside of rolling is that it can leave polo shirts a bit wrinkled. Address this problem by giving yourself some time to steam a shirt after unrolling it.\n2. Fold the shirt in from the bottom. Lay your polo shirt on a flat surface with the buttons facing up. Grasp the bottom edge of the shirt and fold it upwards about 4 inches (10 cm). This will shorten the total length of the shirt and help you to create a tighter roll.\n3. Fold in the sides. Grab one side of your polo shirt, place the sleeve facing outward, and fold the fabric inward toward the center. Do the same thing with the other side of the shirt. This means that the outer edges of your shirt will now meet in the center with overlapping sleeves.\n4. Start rolling from the collar. Grab the collar in both of your hands and begin rolling downwards. Try to keep your hands firm on the fabric, so that the final roll is tight and secure. When you reach the bottom of the shirt, press lightly against the sides of the roll. The final roll should be around 6 inches (15 cm) in width.\n\n\n## Clean your polo shirt before store\n\n1. Wash the shirt according to the instructions. Locate the tag on your polo. It will probably be at the collar or on the inner side-seam. Read how to wash your polo and follow these directions exactly. For 100% cotton polos, this will usually mean washing them on a warm water setting. For mixed fabric blends, it is usually safer to go with a cold water setting. It’s also okay to hand wash most polos, as long as you stick with the same suggested water temperature.\n2. Dry the shirt. You really want to avoid shrinking your polos, so make sure that you follow the drying instructions as well. If you machine dry your polos, use the lowest heat setting. It’s better, though, to hang your polo shirts up on a drying rack until they are fully dry. This will keep your shirts looking the best for the longest period of time. Be aware that drying your polos on a rack might make them look more wrinkly. However, this can be quickly fixed with a round of steaming or ironing.\n3. Remove any wrinkles with steaming or ironing. Get out your ironing board and set your iron to a medium or low heat setting. Go over your polo with the iron, keeping it moving to prevent burning the fabric. Look at the tag for any additional instructions. Some polos need to be turned inside out before ironing. You can also hang up your polo and use a steam machine to work out any wrinkles. Pass the steamer wand close to, but not touching, the fabric until it smooths out. Polo shirts have a tendency to get particularly wrinkly around the collar, so pay additional attention to this area. Also, make sure to reinsert any collar stays after you are finished steaming or ironing your shirt.\n"}, 4] | |
| [{"Instruction": "How to comfort a dying dog at home or vet?", "Response": "Although it is a natural part of life, it is never easy saying goodbye to your beloved canine companion. During this stage of life, you will want to make your dog as comfortable as possible. The comfort you provide throughout this potentially frightening situation will make the transition easier for your dog and bring you peace of mind as well.\n\n## Comfort your dog at home\n\n1. Stay patient with your dog. Older dogs commonly begin experiencing joint and muscle problems, and they can become frustrated with their discomfort and impairments. If your dog is grumpy or irritable during the end stages of life, simply do your best to be patient and provide the other comforts you can at home.\n2. Provide a quiet environment. Chaos around the home will only stress both you and your dog as you're trying to spend the final hours of your dog's life together meaningfully and with compassion. Give your dog a quiet environment away from noisy children or other animals in the house. Soft, unobtrusive music can also be calming, or you may also use a nature soundtrack with birdsong and the sounds of running water.\n3. Speak in comforting tones. Reassure your dog that he's not alone and speak in soft comforting tones. Tell him “good boy” and the other phrases you normally use for positive reinforcement to let him know it's okay. Give him plenty of light pets as well. If you want to make sure you're there for the final moments, then you may choose to sleep next to his bed in a sleeping bag for the final nights.\n4. Put down comfortable bedding. If your dog has a favorite dog bed, put it down for him. Otherwise you can put down some other blankets to help him lay down comfortably. Your dog may also have difficulty regulating his body temperature at the end, so keep some blankets handy to put over him in the event that he shows signs of being cold. Elderly dogs are also prone to pressure sores, so put down extra cushioning for an older dog. On a practical note, he may also have problems with incontinence at the end. Choose a spot you can easily clean and bedding you can wash later. If your dog does have any accidents, then clean them up patiently without scolding him. He can't help it. If your dog gets cold, you can also use a heater in the area to make him more comfortable.\n5. Keep fresh water available. Hydration is still important to keeping your dog comfortable even in the final hours. Provide a bowl of water next to the dog bed, so your dog doesn't have to get up to drink. If your is having trouble rising even to drink, then use a clean dropper to help provide water.\n6. Prepare some of his favorite meal. If your dog has always had a favorite thing to eat, then you should make some of it in case he's hungry. However, it is pretty common for dogs to lose their appetite in the end stages of life, so don't force him to eat if he's not hungry. Solid food may also upset your dog's stomach at the end as certain systems related to digestion begin shutting down. If your dog still shows a willingness to eat but regular food is upsetting his stomach, then try mixing some baby food with water, or you can also try the Hills A/D diet, which is liquid.\n7. See your veterinarian about pain management. If your dog still has enough time and you're worried about pain in the final stages, then you can consult your vet for pain management options for the final days. Signs that your dog might be in pain include excessive panting or gasping for breath or reluctance to move.\n8. Hug your dog one final time. Once your dog passes, give him one final hug and say goodbye. It's a very painful moment, so remember that it's perfectly okay to cry, but also remember the good times you had with your pet and that he passed in a comfortable, loving environment with you doing everything you could. Be aware that some dogs seem to \"move\" or \"take a breath\" after passing away. As their nervous system shuts down, sometimes muscles in the body or lungs can spasm and look like a sign of life. It's also common for dogs to pass with their eyes open. You can close them if you want as you say your final goodbye, or you can pull one of the blankets over his head.\n9. Take care of yourself. Once your pet has passed, know that you did everything you could and worry about taking care of yourself. Seek comfort in other loved ones who understand the loss. You can also light candles or say a small prayer for your pet if it feels right and helps. The ASPCA also has a hotline you can call to talk to someone who understands the difficulty of losing a pet. You can reach this hotline at 1-877-GRIEF-10.\n10. Handle your pet's remains. Though it's unpleasant, you do have to do something with your pet's remains once he passes. Many people choose to cremate pets or bury them whether in a pet cemetery or closer to home. Many services are available to help you deal with the remains to make the process easier on you. Look online or ask your vet for services in your area that will help with the option of your choosing.\n\n\n## Comfort your dog at the vet\n\n1. Consult a professional about euthanasia. The ASPCA has a specific hotline for those dealing with the difficult decision of euthanizing a pet. The line gives you someone to talk to who will understand your grief throughout the process, as well as information about your dog's quality of life at this stage and whether or not euthanasia may be the most humane option. You can reach the ASPCA hotline at 1-877-GRIEF-10.\n2. Make the appointment. Though it hurts to do and it always feels too soon, you'll have to make an appointment for the vet to euthanize him when you know your dog is at the end of life. Your vet is likely to suggest this option if your dog's condition has significantly deteriorated and the vet believes the dog is in pain.\n3. Bring some of your dog's favorite items. You'll want to surround your dog with a few of his favorite things at the end. A favorite blanket and a soft toy are very common items that you may choose to bring with to help comfort him as he passes. Favorite blankets or a dog bed will also be much more comfortable for your dog than the exam table, especially if he's already in discomfort.\n4. Sign any forms at the vet. When you sign in for the appointment, you'll also have a few forms to fill out, including a consent form signaling that you know what is about to happen. While filling out forms is the last thing you want to focus on, it is a necessary part of the process.\n5. Ask about a sedative beforehand. If your dog is experiencing any pain or discomfort from a medical condition, ask the veterinarian about giving him a sedative. This will make your dog more comfortable, and it will give you the peace of mind later knowing that your dog passed without any pain.\n6. Pet your dog with gentle, loving strokes. Once you've been taken back to the private room and placed your dog down on his blankets with any other items, focus all your energy on spending quality final moments with him. The veterinarian will have to finish setting up the necessary items, so use this time to offer soft praise to your dog. Tell him you love him and pet him in his favorite spots.\n7. Hug your dog. Your vet will ensure you're ready and then begin injecting the solution to euthanize your dog. Many people choose to hug their dog during these moments because the process is fairly quick. Between six and twelve seconds after the solution is delivered, your dog will take a deep breath and then appear to fall into a deep sleep before taking a few more final breaths. Some pet owners also prefer not to be in the room for the actual injection and passing. The veterinarian's office is used to people who need to cope and grieve in their own ways. Ultimately decide what is right for you.\n8. Give yourself time. Do not be embarrassed to cry in front of the vet or other employees at the clinic. They all understand what you're going through. After your dog has passed away, your veterinarian will give you the option to spend some additional one-on-one time with your dog. Some owners take this opportunity to say a few last words to their dog while others choose to pass on this option.\n9. Discuss options for the remains. After giving you the time you need, your vet will discuss options concerning what to do with your dog's remains. This may include releasing them to you for burial or cremating them, which the vet can take care of. You can choose cremation either with the intent to take the cremains with you or not. In some places, it is against the law for the vet to return your pet's body to you for burial.\n"}, 5] | |

However, it's not recommended, and it's much better and flexible to use ```?=``` assignment (the conditional variable assignment operator, it only has an effect if the variable is not yet defined):\n```FOO?=default_value_if_not_set_in_environment\n```\nNote that certain variables are not inherited from environment:\n\n* ```MAKE``` is gotten from name of the script\n* ```SHELL``` is either set within a makefile, or defaults to ```/bin/sh``` (rationale: commands are specified within the makefile, and they're shell-specific).\n\n* From command line - ```make``` can take variable assignments as part of his command line, mingled with targets:\n```make target FOO=bar\n```\nBut then all assignments to ```FOO``` variable within the makefile will be ignored unless you use the ```override``` directive in assignment. (The effect is the same as with ```-e``` option for environment variables).\n* Exporting from the parent Make - if you call Make from a Makefile, you usually shouldn't explicitly write variable assignments like this:\n```# Don't do this!\ntarget:\n $(MAKE) -C target CC=$(CC) CFLAGS=$(CFLAGS)\n```\nInstead, better solution might be to export these variables. Exporting a variable makes it into the environment of every shell invocation, and Make calls from these commands pick these environment variable as specified above.\n```# Do like this\nCFLAGS=-g\nexport CFLAGS\ntarget:\n $(MAKE) -C target\n```\nYou can also export all variables by using ```export``` without arguments."}, 5] | |

Julia has much more limited algorithm support but does exhibit a good turn of speed.\nThe few algorithms that Mathematica does support are not particularly well exposed for the type of tweaking needed to win Kaggle competitions.\nMathematica, as of version 10, supports the following classifiers: \"LogisticRegression\", \"Markov\", \"NaiveBayes\", \"NearestNeighbors\", \"NeuralNetwork\", \"RandomForest\", \"SupportVectorMachine\". \nWhilst it does offer one ensemble method, RandomForest, it lacks both Bagging and any flavour of boosting, such as Adaboost. These latter general ensemble methods allow you to leverage the power of a base classifier, either built-in or, of greater utility when exploring performance improvements, of your own design. This limits significantly the potential for creating novel methods within the existing machine learning framework. \nMathematica's strengths lay with it's expressive, compact, language, strong visualisation capabilities and easy parallelization. These make it very efficient to explore new strategies and combinations of ML algorithms you may already have implemented.\nA less often mentioned benefit is that use of Mathematica in a functional programming style tends to lead to fewer bugs in the final code."}, 3] | |

You need to use the diskpart utility to remove the partitions and create 1 single partition covering the full volume.\n```diskpart``` can be a bit dangerous, because if you pick the wrong disk or partition, you can remove data or partitions that are extremely, EXTREMELY important and lose all data on your machine. \nProceed with extreme caution!\nOpen up a command prompt as administrator (open the start menu, type ```cmd``` and press Enter.)\nType ```diskpart``` and press Enter. You'll end up with a new prompt that looks like this:\n```DISKPART>\n```\nType\n```list disk \n```\nand you'll get a listing of all drives on your machine. \nType\n```select disk # \n```\nto select a disk, where ```#``` is the number of the disk Windows screw-balled.

Wait at least 5 minutes, then re-insert the drive. DO NOT CLICK FORMAT – this will most likely re-create the problem. Instead, enter diskpart again, and select the disk. Then type\n```create partition primary \n```\nOnce you have created the partition, exit ```diskpart``` and, in the command promt, type \n```diskmgmt.msc \n```\nThis will provide a reliable way to create a FAT32 partition. On the drive you would like to format (NEVER TOUCH DISK 0!), right click and select ```format```.

The equipment used aboard the Lunar Module to make the recordings was called the Data Storage Electronics Assembly (DSEA). It made recordings onboard the Lunar Module, but the DSEA flown on the Eagle during Apollo 11 malfunctioned.

In raytracing you just look up the ray intersection, whereas in ray marching you march forward (or back and forth) until you find the intersection, have enough samples or whatever it is your trying to solve. Try to think of it like a newton-raphson method for surface finding, or summing for integrating a varying function.\n\nThis can be useful if you:\n\n* Need to render volumetrics that arenot uniform\n* Rendering implicit functions, fractals\n* Rendering other kinds of parametric surfaces where intersection is not known ahead of time, like paralax mapping\netc.\n\n\n## Sphere tracing\nSphere tracing is one possible Ray marching algorithm. Not all raymarching uses benefit form this method, as they can not be converted into this kind of scheme.\n\nSphere tracing is used for rendering implicit surfaces. Implicit surfaces are formed at some level of a continuous function. In essence solving the equation\n```F(X,Y,Z) = 0\n```\n\nBecause of how this function can be solved at each point, one can go ahead and estimate the biggest possible sphere that can fit the current march step (or if not exactly reasonably safely). You then know that next march distance is at least this big. This way you can have adaptive ray marching steps speeding up the process."}, 4] | |
| [{"Instruction": "How to lighten pigmentation in bikini areas naturally?", "Response": "For all kinds of reasons, some people develop pigmentation in the bikini areas. However, it doesn't have to be a permanent issue. There are a variety of effective, lasting ways to address it. By safely lightening these regions, your skin can have a beautiful, even tone in the bikini areas once again.\n\n## Lighten the bikini areas with home remedy\n\n1. Use Papaya Soap. Papaya soap is natural and using it regularly will help to lighten the skin. Use it at least twice a day, once in the morning and once at night, until you see results. Keep your skin moisturized because it can dry out your skin. You can also mash up a chunk of ripe papaya, and apply a big dollop on the areas. Leave it on for 30 minutes and then wash it off. In a couple of week's time, you should see significant lightening.\n2. Apply glycolic or salicylic acid acne pads. These two ingredients are the lightening agents used for acne treatments and can also be used for this purpose. Dab a pad on the areas and then get into the shower. Let the steam sink in for a couple minutes and wash off. Don't do this treatment immediately after shaving, however, as it could irritate it.\n3. Use a lemon juice, yogurt mix. Mix juice from 1/4 lemon into a tablespoon of yogurt, and apply to the area. It acts as a mild bleaching solution that will safely lighten it. Apply aloe vera gel afterwards to keep your skin moist and hydrated. Don't do this treatment immediately after shaving, however, as it could irritate it.\n4. Apply almond paste. Soak several almonds for 24 hours. Then slide the skins off, and add a couple drops of milk to make a paste. Put on the bikini areas, and leave on for an hour. Wash off with warm water. If used regularly, it works as a mild lightener and also exfoliates and softens the skin.\n5. Try using milk to lighten and moisturize your skin. Pour some milk into a bowl and dip into with a cotton ball. Dab onto your skin. Milk is a natural skin lightener, and it also won't dry it out. It's not going to happen overnight but with regular use, you will see some slight results.\n6. Apply peroxide onto the area. Wipe off after 15 minutes. Do this a couple of times a day until you see results. Peroxide is highly acidic, so you may want to apply a little almond or coconut oil on the area after washing it off. Don't do this treatment immediately after shaving, however, as it could irritate it.\n\n\n## Go to a dermatologist to correct the problem\n\n1. Ask the doctor about using a skin bleaching cream containing hydroquinone. This kind of cream works by preventing melanin from being produced in the skin. It's one of the most popular lightening treatments. However, if the concentration is too high or if it's used for too long, it could worsen the discoloration or reverse the effects. It can also be toxic to the liver.\n2. Talk to your dermatologist about a milder skin bleaching treatment. Some alternative, fading creams that are known to have less side effects are azelaic acid, kojic acid and one containing only 2 percent hydroquinone. All of these are known to help with persistent or residual skin discoloration problems. They work by preventing keratin, a hair protein, from being produced in the skin.\n3. Find out from your doctor if you're a good candidate for using a bleaching agent, such as chlorine, to lighten the areas. This is a mix formulated by the medical professional doing the treatment. Due to the concentration of bleach, dermatologists and medical doctors are the only ones allowed to administer it.\n4. Opt for laser hair removal. If the darkening is caused by waxing, shaving, and/or you can see dark hair stubble as it's growing back, then laser hair removal may be a good solution for you. Though it's considered semi-permanent, the hair usually doesn't come back. However, you have to make sure to complete the recommended number of treatments and the ongoing, but infrequent, touch-ups.\n\n\n## Prevent darken of the bikini areas\n\n1. Exfoliate the area. Old skin cells don't just build up on your knees and elbows but on other areas of the skin as well. When they accumulate, they can make the skin appear darker and duller. Prior to shaving, lightly exfoliate the region using a loofah, scrub or exfoliating brush. This will remove the dry skin and will also help to prevent skin irritation and ingrown hairs in the bikini areas.\n2. Use sunblock. When going in the sun, use a sunblock to keep the sun from penetrating those areas of your skin that you don't want getting darker. Choose a sunblock with a high SPF number (Sun Protection Factor) such as SPF 45 on that region. Also when you come out of the sun, apply olive oil to the area, as it's also known to be a natural skin lightener.\n3. Wear breathable, cotton clothing that is loose and comfortable. Sweating in the bikini areas are known to cause darkening. Avoid polyester clothing and other synthetic fabrics, as they don't allow the skin to breath. Also tight clothing sometimes causes chafing and could also darken these areas.\n4. Use a quality razor, and shave gently in the direction of the hair growth. If shaving irritates the skin, it could darken it. Basically, dark spots are caused by constant friction. If you shave every day, your skin attempts to protect it so it darkens up. Any type of injury to your skin will either create a stain or keloid. Waxing can also cause darkening if it's too hot.\n5. Eat more vegetables and fruits. Fruits, oranges and berries, in particular, and green, leafy vegetables have lots of antioxidants that assist in reducing discoloration of the skin. Drinking water also helps to flush toxins out of the body.\n6. Drink more water. It is one of the best ways to detoxify. There is no one-size-fits-all to how much water a person should drink. As a general rule, though, women should drink 128 ounces a day, and men should consume 128 ounces of water a day.\n"}, 4] | |
| [{"Instruction": "Teach me how to dance the Charleston.", "Response": "The Charleston is a medium- to fast-tempo dance that originated in the 20s. It was renowned for being the first social dance one could do without a partner. There are several versions of Charleston, the most popular being the 20s and 30s Charleston. The Charleston is a highly adaptable move that can be incorporated into a wide variety of dances, but the basic movement is the same.\n\n## Master the basic move\n\n1. Take a rock step back with your left foot. Touching the front of your foot to the floor, but not bringing your heel down. Don’t fully shift your weight to this foot. When doing the Charleston, lean forward slightly and bend your knees a little. Keep your weight on the balls of your feet. A rock step, also called a break step, refers to a rocking step in which one’s weight is very briefly transferred to another foot before being returned to the first. The only time when you might begin with your right foot is if you are following a partner. When two people dance the Charleston together, the leader starts by stepping back on the left foot, while the follower starts by stepping back on the right, mirroring the leader.\n2. Step back forward with your left foot. It should now be a step ahead of your right foot. This time, shift your weight to your left foot.\n3. Take another rock step forward with your right foot. Put the heel of your foot on the ground without bringing your whole foot down. Your weight should end up on your left foot still.\n4. Step back with your right foot. It should now be a step behind your left foot. Shift your weight back onto your right foot.\n5. Swing your arms as you step. As you move, your arms should be swinging. This may happen automatically, especially if you’ve seen people do the Charleston before and know what it’s supposed to look like. When your left foot is in front of you, your right arm should swing forward. When your right foot is in front of you, your left arm should swing forward.\n6. Repeat this movement. It probably won’t look terribly impressive on its own, but the back, forward, forward, back motion is the building block for every variation on the Charleston. Practice until it feels natural. Then you’ll be ready to start mixing things up.\n\n\n## Do the 20s charleston\n\n1. Get comfortable with the basic move. All the variations of the Charleston start with being able to do the basic step. Practice until it becomes second nature.\n2. Twist your feet in and out. Keep your weigh on the balls of your feet. On every step, the heel of the foot your have your weight on should twist out and then in again.\n3. Lift your elbows as you swing your arms. This is basically an exaggerated version of the arm swing. As always, your left arm should swing forward when your right foot is ahead of your body, and your right arm should swing forward when your left foot is in front of your body. Your arms should be bent at about a 90 degree angle. The elbow of the arm that is swinging back should come to shoulder height, and the forearm of the arm that is swinging forward should be parallel to the ground.\n4. Pivot your knees in and out. One common move used with the Charleston involves opening and closing your knees at the same time as crossing and uncrossing your arms. This may be the most well-known Charleston move. Begin with your knees bent and touching each other, with your arms crossed over them, so that your right hand is on your left knee, and your left hand is on your right now. Spread your knees apart while simultaneously uncrossing your arms, so that you end up with your left hand on your left knee, and your right hand on your right knee. #\\*Repeat this move a few times.\n\n\n## Do the 30s charleston\n\n1. Get comfortable with the basic move. All the variations of the Charleston start with being able to do the basic step. Practice until it becomes second nature.\n2. Replace a normal step with a kick step. This will add a little pep to the move. Instead of simply stepping forward, bring your knee up and kick your foot out. Your knee should come up first, propelling your foot forward a moment later. If you would not be transferring your weight to that foot anyway for this step, just swing it back again without letting it touch the ground. Otherwise, plant it back on the ground after the kick.\n3. Add a hitch as you move your leg back. Instead of simply stepping back after a kick, incorporate a hitch into the movement. Bring your knee back up, so that your upper leg is parallel to the ground, before kicking your foot back again.\n4. Touch the ground with your hand. This adds slightly more difficulty and flare. As your leg swings back and the ball of your foot touches the ground, lean forward and tap the ground with the tips of the fingers of your opposite hand.\n"}, 4] | |
| [{"Instruction": "Explain the \"cards speak\" rule in US casinos.", "Response": "Casinos in the US generally have the \"cards speak\" rule. That is, when a hand is properly tabled--exposed to everyone at showdown--it is the responsibility of all players, the dealer, floormen, and anyone else present to see that the pot is awarded to the best hand shown, regardless of what the players might say.\n\nSome players object to this rule: they believe that if a player or railbird says \"Wait, Bob has a flush\", that's unfairly helping a player. But the rule is clear: once the hand is tabled, others have not only the right but the obligation to help ensure the pot is awarded correctly.\n\nThere are a couple of caveats: if a player only shows his hand to another player, or to the dealer, or to any other person, without properly tabling it for everyone, that player has no rights yet and those to whom the hand was shown should remain silent to protect other players' properly shown hands. But once the hand is tabled, it's fair game and everyone can and should assist in reading the hands.\n\nFinally, in some cases, if a floorman feels that a player has deliberately overcalled his hand to induce a player with a better hand to fold, he may penalize that player by awarding the pot to someone else, even possibly to a folded hand. Some California lowball clubs even had a rule that a player who remained silent rather than explicitly calling out a pair could be ruled against in this way."}, 5] | |

| [{"Instruction": "Give tips to reduce life stress and improve well-being", "Response": "## Reduce the pressure of life\n\n1. Start a stress journal to identify and reflect on the sources of pressure in your life. Are you experiencing financial pressure? Are you experiencing stresses at a new job or as a result of a job loss? A stress journal can help you identify the most significant sources of stress in your life and how you cope with them. This self knowledge will help you tackle the biggest stressors in your life. You can also reflect on the specific situations within which you experience higher stress levels. Do you experience more stress at particular times of the week or in particular spaces (e.g., a conference room) at work? Are there ways of avoiding such situations entirely, or responding more effectively to them? Reflect on these kinds of questions and work towards insights on how to manage stress through journaling. Create a list of everything you are grateful for in your life. Recognizing the good things in your life can help reduce stress and anxiety.\n2. Take a stress assessment test. There may be stressors that are so normal in your life that you don't even realize they're stressing you out. A stress assessment test can help you identify these hidden stressors. There are many online tests that you can do. You can take a free stress assessment test online at https://www.stress.org/self-assessment/.\n3. Make a plan to tackle the sources of pressure in your life. Utilizing the information from your stress journal, you may decide that you need a revised financial plan, a personal health plan or a work plan. The most important thing is to tackle the sources of pressure through a purposeful and detailed plan of action. Talk to your supervisor to create a plan of action to reduce the stressors you experience at work. Make a financial plan with specific targets, including not only long term savings or retirement goals but also near term goals that are concrete and achievable. Build up your emergency or rainy day fund. Make a fitness plan to improve your health.\n4. Overcome perfectionism. A huge source of pressure in life can be the desire to be perfect at everything. Have you ever been told that you have unrealistic standards at work? Do you ever feel you will never be able to live up to your own standards? If you answered yes to these questions, you may have difficulty with perfectionism. If so, try to loosen up your standards of achievement a little bit. This should help reduce your anxiety levels. If you feel disappointed with yourself, try repeating statements like \"nobody is perfect\" or \"I did my best\"\n\t* Try to think about your situation from a different angle. Ask yourself, will this situation still matter next month? If I told my brother or friend about this situation, would they think it matters as much as I do? Gain some perspective on your situation and maybe it won't seem quite as dire as it does right now.\n5. Create work-life boundaries so that you have time for yourself. Living in a digital age with constant access to screens - computers, tablets, smart phones - can make it difficult to escape the pressures of work. The pressure to be always online and accessible to colleagues can take a toll on work-life balance. To manage this kind of stress, it is helpful to create boundaries for yourself such as telling your colleagues you will be away from the phone or the computer at certain times of the day or on the weekend. Tell your colleagues you will be away from email and phone connectivity during dinner hours.\n6. Avoid comparing yourself to other people. If you're constantly trying to be someone you're not, you will feel stressed or burdened. Don't judge yourself based on how you think other people are living their life.Remind yourself that you have talents, skills, qualities, and good characteristics that are unique to you. Evaluate your goals and successes based on you want out of life, not what others want for you. Try to reduce how much time you spend on social media. People often post the best parts of their life on social media, so it may seem as though their lives are more perfect than they actually are.\n7. Give yourself some time away from work. If you are feeling burned out, it might be time for a personal day or even a vacation. Taking a vacation can actually help your productivity, and has obvious health benefits. If you don't have time for a vacation at the moment, try to at least take the weekend off to catch up on sleep. If you have vacation time or time off from work, take advantage of it. Those days are there for you to use them. A vacation might make you more productive.\n8. Set up an automatic 'out of office' reply on your email account. By setting up an automatic reply on weekends or when you are on vacation, you will not feel guilty for ignoring work emails. Also, your colleagues will be more likely to respect your away time. Include details on the days and times you are away in your 'out of office' automatic email reply. Include a fun or wise quote in your automatic reply so that colleagues will be reminded of your personality or sense of humour. This may reduce the annoyance of getting an automatic reply.\n\n\n## Take care of yourself\n\n1. Start a regular exercise routine. Exercise has been shown to reduce stress, improve feelings of well being and self esteem. Engaging in physical exercise leads to the production of the neurotransmitter endorphin, which is associated with improved sense of well being or what some people call runner's high. You don't need to be an athlete to experience this improved mood, and just 15 minutes a day can make a big difference..\n\t* After your exercise routine, try using a heat wrap around your neck and shoulders for 10 minutes to reduce tension in your upper body.\n2. Practice meditation. Find a comfortable place to sit in a quiet room or in a park. Observe the movement of your breath as it comes into your body and then flows out. Let go of passing thoughts. You can also do a walking meditation by walking slowly, preferably in a natural area, while watching your breath. Meditating for a few minutes a day can help reduce stress and anxiety. Deep, diaphragmatic breathing can reduce the heart rate and lower anxiety. [Image:Lessen the Pressure of Life Step 8.jpg|center]]\n\t* Meditate alongside your yoga practice and in your everyday life. Mindfulness-based stress reduction such as meditation and yoga are helpful in reducing stress and anxiety, including amongst college students.\n3. Eat whole plant foods as part of a healthy diet. Whole plant foods such as whole grains (e.g., brown rice), vegetables, and fruits are negatively associated with depression and anxiety. On the other hand, processed food (e.g., canned food) has been positively associated with stress and anxiety. Drink a cup of herbal tea.\n4. Ditch your second cup of coffee. Caffeine can exacerbate stress levels, so it is good to lower your caffeine intake as part of an overall stress reduction plan. Keep in mind that you may experience withdrawal symptoms, especially if you are a heavy coffee drinker.\n5. Cut down on sugar. Stress can make you crave sugary foods, but try to resist temptation. Giving in to these urges will not actually make you feel any better. Too much sugar can cause your blood sugar to crash, which can cause more stress and cravings.Sugary foods include most desserts, baked goods, soft drinks, juices, and candy.\n6. Reduce your consumption of alcohol. Although many turn to alcohol to deal with the everyday pressures of life, alcohol consumption can actually compound the impact of stress on the body and mind. Alcohol can also make your financial anxieties worse.\n\n\n## Gain perspective on life\n\n1. Talk to your friends and family about the sources of stress in your life and about everything you are grateful for. Face to face conversations with friends and family are especially important in helping reduce the pressures of life. Plan a movie night with close friends and pick a comedy! Laughing lowers cortisol which is the body's stress hormone. Go to a concert with friends. Listening to music can help reduce stress. So why not make a night of it and decompress with friends and music you love.\n2. Use positive thinking and self-talk to ward off stress. For instance, if you are experiencing a lot of stress at work due to an impending deadline, remember to tell yourself, “I can overcome this hurdle”\n3. Avoid trying to control everything in your life. Sometimes, there are surprises in life. You can't always predict or control what will happen. Letting go of the need to control everything can help you become happier and more at peace with the world.\n4. Express yourself through art therapy. Tapping into your creative side can help you work through the anxiety of everyday life. Using art therapy techniques, preferably alongside an art therapist, you can use drawing, painting, or music to express your inner feelings in more nuanced ways than may be possible with words alone. You don't have to be an artist to enjoy the benefits of creative self expression, including in relation to stress reduction.\n"}, 4] | |

The main objection was to the boardgame we were publishing, The Battle of Five Armies. The author of that game had given us a letter from his attorney claiming the work was grandfathered because it was published after the copyrights for JRRT's works had lapsed and before any renewals were made. The action also demanded we remove balrog, dragon, dwarf, elf, ent, goblin, hobbit, orc, and warg from the D&D game. Although only balrog and warg were unique names we agreed to hobbit as well, kept the rest, of course. The boardgame was dumped, and thus the suit was settled out of court at that.\n\nHalflings were originally called "hobbits" in the Dungeons & Dragons box set first released in 1974. Later printings changed this to "halfling".\nAccording to The Acaeum, this change occurred between the fifth printing (Dec 1975 - Apr 1976) and sixth printing (1977), with the six printing being marked the Original Collector's Edition. However, Tim Kask has said that box sets were generally thrown together with whichever printings of the books were on hand, so the distinctions between printings are inexact. The Acaeum notes at least one box set shipped having the revised booklets but no Original Collector's Edition mark.\nDue to an oversight, a single reference to "hobbit" remained on page 6 of Men & Magic, which was fixed in the 2013 Deluxe reprint and PDF copies.\nAccording to Wikipedia, J.R.R. Tolkien sold the film, stage, and merchandising rights to The Hobbit and Lord of the Rings to United Artists in 1968, who sold them in turn to Saul Zaentz in 1976. Zaents would go on to produce the 1978 Lord of the Rings animated movie."}, 3] | |

| [{"Instruction": "How to comfort a grieving dog after owner's death", "Response": "## Comfort the dog\n\n1. Spend extra time with the dog. A dog in mourning may need extra love and attention. Try to increase the amount of time you spend with the dog. You might spend twenty extra minutes in the morning and evening to help give the dog support while they are grieving the death of their owner. During this time, you can:\n\t* Talk to the dog\n\t* Walk the dog\n\t* \n\t* Groom the dog\n\t* \n\t* Go on a car ride\n\t* Visit the dog park\n\t* Pick out a new toy together at the pet store\n\t* Cuddle the dog on the couch or in bed\n\t* Take the dog for a run, if the dog is healthy enough\n\t* Play a game, like fetch or tug-of-war\n2. Pet the dog. Touch increases the bond between dogs and people. Extra cuddling, petting, and brushing can improve the dog’s mood and distract them from the loss of their owner. As you spend time with the dog, rub their belly or scratch their ears. Give them a little extra grooming time each week. This will help you bond and comfort the dog.\n3. Play their favorite games. Playtime can distract the dog from the loss of their owner. The extra exercise can also boost their mood and decrease the likelihood of grief-related health issues. Try to identify the dog’s favorite games or toys, and spend extra time playing with them. Some older dogs may not want to play as much. Each dog is different. If the dog is uninterested in playing, you might try another way of distracting them. You can also give the dog new and interesting toys. Food puzzle toys can help keep the dog busy while you are not home, reducing the dog’s separation anxiety.\n4. Invite company over. The dog may appreciate having people over to spend time with. Invite a few friends over, and see how the dog reacts. If the dog enjoys the company and socializes with the people, you may want to keep it up. If the dog avoids your guests, you should respect their space. Inviting people or dogs that the dog already knows may cheer the dog up. It can also introduce an element of familiarity in their new life. If the people are total strangers to the dog, invite one or two over at a time to see how well the dog handles it.\n\n\n## Monitor the dog’s health\n\n1. Identify physical symptoms of mourning. Dogs mourn differently from humans. While some dogs may not mourn at all, others will become extremely clingy, anxious, or lethargic. Keep an eye out for the following symptoms. If they do not disappear after a few days, you might consider seeking help from a vet or dog behaviorist. Lethargy or lack of energy. Lack of interest in playing\n\t* Loss of appetite\n\t* \n\t* Unsociable behavior\n\t* Increased sleeping\n\t* \n\t* Weight loss\n\t* Decline in physical health\n2. Encourage the dog to eat. It is very common for older dogs to stop eating after the loss of their owner. This can cause other health issues to develop. If the dog seems to have stopped eating, you should try to get the dog to eat. If possible, keep feeding the dog the same food that the old owner fed them. You can also give the dog kibble in a kong-type dog toy or food puzzle. The dog may enjoy trying to get the food out of the toy. Add a little warm chicken broth to the dog’s dry food to make it softer and more enticing. While a few extra treats here and there may not be detrimental to your dog, you should avoid giving the dog too many treats during this period. They may learn that they will be rewarded for whining, and they may not eat their normal food.\n3. Take the dog on walks. Older dogs may not be extremely active to begin with, but they may become more lethargic after the loss of their owner. Such inactivity can lead to further health problems. If the dog is able, take them on a walk at least once or twice a day. Depending on the age and health of the dog, these may be short walks. You can make even short walks more mentally stimulating for the dog by walking in areas with lots of interesting sights, sounds, and smells. For example, you might take your dog to the park, through the woods, or some place with water.\n4. Take the dog to the vet. If the dog continues to mourn for several weeks or if the dog is not eating, you should visit the vet to make sure that the dog is still in good health. The vet can diagnose an underlying medical problem or prescribe medication to help with the dog's anxiety or depression. While at the vet, you might ask:\n\t* \"What medical issues does this dog have? Can any of them be aggravated by the loss of their owner?\" \"The dog seems really depressed. What can I do to help?\" \"The dog has been sleeping a lot since I took them in. Is this because the dog is depressed or is there another issue?\" \"The dog has not been eating since their owner died. What can I do to encourage them to eat?\" If you know which vet the dog's old owner used, you should take them there. The vet can inform you of the dog's medical history.\n\n\n## Provide a happy home\n\n1. Maintain a routine. For the first few days after the owner has died, it is important to maintain the dog’s routine as much as possible. Older dogs tend not to do well with new habits, schedules, or activities, and the owner’s death may have already disrupted their life. Try to feed and walk the dog at the same times as the old owner did. If you can, reach out to people who knew the dog when it was with the old owner, and see if they have an idea of what the dog’s former routine was like. If you do not know what schedule the old owner kept, you can develop a new schedule for the dog. Keep a consistent routine for the first few weeks that the dog joins you. The dog may also prompt you when they expect to be fed or taken outside. If there has been upheaval in the dog’s life since the owner died (for example, if the dog has been passed around by family members or if you adopted the dog from a shelter), setting a routine will be even more important for the dog. Make sure that you stick to the schedule to help the dog ease into their new home life. Be careful not to let the dog fall into bad habits due to grief. For example, if the dog turns up its nose at food, just let the food sit there until the dog is ready to eat it. Don’t “reward” the behavior by making a fuss.\n2. Take care of your own grief. If you knew the old owner, you may be grieving yourself. This is understandable. Do what you have to so that you can grieve in your own, personal way. This will in turn help the dog by providing a loving, happy home for them. Avoid mourning in front of the dog. Dogs are very sensitive to grief, and they may exhibit signs of mourning if they understand that you are grieving. While it is okay to cry a little in front of the dog, you may want to step into another room to mourn privately.\n3. Reinforce positive behavior. During this time, you may notice that the dog is whining, crying, or acting out. While you may want to give the dog a treat during these episodes, you should avoid rewarding them for this behavior. The dog may learn that they will earn treats if they whine. Instead, reward the dog when they are being good, such as when they are quietly resting. For example, you may notice that the dog is sitting outside of your bedroom door at night and whining. Instead of waking up to comfort the dog, go back to sleep. In the morning, you can pet and talk to the dog. If they are well-behaved, give them a treat with their breakfast. Good times to treat the dog are when the dog is resting quietly, when the dog is sitting with you, or right before you leave the house.\n4. Weigh the pros and cons of getting a new dog. While a new dog companion might provide company for the dog, many older dogs do not do well with a new younger dog in the house. While some older dogs may enjoy having a puppy around, others may snap at the younger dog or bully them. Consider carefully whether a new dog is appropriate for the older dog. Also keep in mind that bringing in a new companion for the dog will not make them miss their old owner any less. If a friend or family member has a puppy, ask if they can be introduced to your older dog. This will show you how well the dog deals with energetic puppies. If the older dog plays, cuddles, or gets along with the puppy, you might consider getting a younger dog. Try taking the dog to a dog park when it’s not too crowded, and see if the dog seems to enjoy being around other dogs. If so, then you might consider bringing home a new dog. Another option is to adopt an older or senior dog. Try to find one with a similar temperament. See if the dogs can meet first before you adopt to see if they are friendly with one another.\n"}, 4] | |

| [{"Instruction": "How to recover from a professional mistake and rebuild your reputation", "Response": "People make mistakes. Sometimes these mistakes are bad enough to cost us the respect of those around us or even our jobs. If you’ve made a bad professional error or hurt colleagues at work, though, the damage might not be permanent. You can put the past behind you, but you’ll have to work hard to rebuild relationships, become a model worker, and, in some cases, manage your reputation online.\n\n## Rebuild relationships\n\n1. Admit your mistake. If you’ve damaged your reputation – wronging a coworker, angering your boss, or just getting an overall bad name – the place to start is to own up to it. Admit the error of your ways. Take stock of your actions and accept responsibility for them, to yourself and in front of others. What happened? Where did you go wrong? Be brutally honest with yourself. For example, do you have bad personal habits? Did you try to cut corners and dodge work? Have you been an office gossip? Or, did you have a serious lapse of judgement? Perhaps you stole someone’s idea and got caught or plagiarized a report. Perhaps you just stole, embezzling money.\n2. Apologize. Even if you don’t have a future at your workplace, you should apologize to the people you’ve hurt. Showing remorse is decent and will help you start to redeem yourself. You will not get very far with building bridges and repairing your reputation if you can’t say sorry. Act as soon as you can. The longer you wait to apologize, the more it seems like you aren’t really that sorry. Don’t make excuses. The point is to show remorse and accept that you were wrong. Don’t insert half-excuses or mealy-mouth language into your apology, for example “I’m sorry if you were offended that I took your idea. I only wanted to improve it.”\n\t* Be humble and own up. For instance, “It was really wrong of me to talk behind your back. I know I’ve hurt you and want to ask for your forgiveness.”\n\t* Be sincere. You won’t get credit if you don’t say specifically what you did. You also won’t credit if you don’t say it apologetically and sincerely, showing that you won't repeat the behavior.\n3. Commit to reform. Besides an apology, write out a plan for how you’ll change and ensure your mistake doesn’t happen again. This can be for you alone or, if you’re lucky to keep your job, to share with the powers that be in the organization. Outline what you did wrong and how you will avoid it. For example, “I made the mistake of getting too involved in workplace gossip and ended up saying harmful things about my coworkers. From now on, I plan to keep my head down, mind my own business, and avoid office politics.”\n\t* Don’t forget to “walk the walk” and follow your plan. You might arrange regular check-ins with your boss, for instance, to discuss your behavior. This will highlight your progress as well as show that you are willing and able to reform.\n4. Keep your attitude in check. Repairing your reputation is going to be a humbling experience. You might feel angry or resentful. You might get annoyed, frustrated, or upset. Keep these emotions under control – you’ve had a bad attitude in the past and need others to see that you’re trying to change. Try to stay calm, collected, and positive. Be aware of the attitudes or emotions that added to your bad behavior in the past. Try to avoid them or situations that bring them out. If your problem is gossip, avoid the office gossipers as best you can. Stop and ask yourself throughout the day, “How’s my attitude? Am I positive? Am I productive?” Catch any problems early and try to readjust your mindset.\n\n\n## Become a model employee\n\n1. Get to work early. Apart from apologies and repairing relationships, set yourself up as a model employee to help you rebuild your work reputation. Be a go-getter. Arrive early and ready to impress. People will eventually start to notice. Getting to work early will make a good impression on your boss and perhaps your coworkers. Often, people aren’t around to see who leaves the office last. But they will notice your presence in the morning. Being early also means you don’t have to rush around. Use the quiet time to your advantage and plan out your day. It doesn’t hurt to take a short walk around the office first thing in the morning. People will see you and take note.\n2. Prioritize. Some people have trouble keeping track of what they need to do during a given day or week. Take initiative and prioritize your work. Keep your nose to the grindstone to avoid returning to past mistakes and to present yourself as great employee. For instance, sit down and write out what you need to do for each day or, longer term, each week and month. If you’ve been coming to work early, use that time to set out daily priorities. Having a to-do list will help you focus your energy. You might also tailor the list to take advantage of your peak work hours. For instance, if you do your best work in the morning, save that time for your top priorities. Try to stick to the list. That said, be flexible in case your boss gives you special instructions.\n3. Do your tasks thoroughly and on-time. Writing down your tasks isn’t all, of course. You actually need to follow through and do them well. Good work and dependability can make a past mistake fade over time. Build up a track record for reliability and your colleagues and boss will have more trust in you in the future. Meet your deadlines. What about that report that’s due next week? Prioritize it in your list on Monday. If you still can’t get it done during the week, consider finishing it at home or over the weekend rather than asking for more time. Be productive, especially if you have had consistency problems before. Take a short breather to stretch or use the restroom, but don’t try to skirt work.\n4. Go above and beyond. Handing in finished work on time is good. To be a model employee, though, you will have to aim even higher and win (or win back) your boss’ trust. Track details, anticipate tasks, and work ahead to further develop a good reputation. If a colleague asks you to think of venues for an upcoming tradeshow, for example, don’t just stop at a list. Take the next steps: call them, ask about availability, and compare prices. When you take initiative like this, you’ll seem smart and like the logical go-to person for key projects.\n\n\n## Repair your reputation online\n\n1. Check your online metrics. If your error was very serious, or if you are well-known and hold a big position, you might want to think about your online presence when rebuilding your reputation. Don’t underestimate negative online info. To start, you will need to take stock of the situation. You can get a quick sense of your online reputation by checking Google’s autocomplete. Just go to the Google homepage. What appears when you type in your name, or your company name? When you enter your name, for example, do you get something positive or neutral like “Harold Bing Brew Co. CEO” and “Harold Bing business award”? Or is it damaging, like “Harold Bing mugshot”? Look at online news stories or reviews about you or your company, if applicable. Check local sites or other social media. Set up a Google Alert in your name, so that you’ll be notified any time something new is posted.\n2. Deal with Google defamation. Programs like Google Suggest reflect real internet searches and should give you an idea of how people associate your name and reputation online. Did you find something unwelcome in your results? There are some things you can do. Do not try to manipulate the results. While some people suggest this approach, using techniques like crowdsourcing, you might end up causing more damage. You might try acquiring the search term and building an optimized page to tell your viewpoint. That way, when someone types “Juliette Page embezzler” she is directed to your side of the story – that the charge is false, misunderstood, or not reported right. You can also request that the search engine take down the autocomplete. This is hard and usually only works with results that suggest hate or violence, porn, or personal information. Still, it may be worthwhile to try.\n3. Hire an online reputation manager. Your online reputation could get out of control. Don’t despair, however. There are people and agencies who can help you manage this kind of situation, like Reputation.com or BrandYourself.com. The work will be pricy, but it may just salvage your working reputation. Reputation managers won’t always be able to get rid of negative content from the web. But they should be able to highlight positives about you. For example, their services might include setting up a domain in your name for a page presenting your side of the story. They can also respond to negative comments or reviews and manage your online presence on sites like Facebook, Twitter, or Youtube. The goal is not to eliminate all negative info about you, but to tip the balance in your favor whenever someone searches for you online. Keep in mind that management services don’t come cheap. Expect to pay between $20 to $200 per month.\n"}, 4] | |

| [{"Instruction": "Explain when to use OAuth 2.0 versus JWT tokens", "Response": "TL;DR If you have very simple scenarios, like a single client application, a single API then it might not pay off to go OAuth 2.0. On the other hand, if there are lots of different clients (browser-based, native mobile, server-side, etc) then sticking to OAuth 2.0 rules might make it more manageable than trying to roll your own system.\n\n## Detailed Answer\n\nJWT (Learn JSON Web Tokens) is just a token format. It defines a compact and self-contained mechanism for transmitting data between parties in a way that can be verified and trusted because it is digitally signed. Additionally, the encoding rules of a JWT also make these tokens very easy to use within the context of HTTP.\n\nBeing self-contained (the actual token contains information about a given subject), they are also a good choice for implementing stateless authentication mechanisms (aka Look mum, no sessions!). When going this route, the only thing a party must present to be granted access to a protected resource is the token itself, and the token in question can be called a bearer token.\n\nIn practice, what you're doing can already be classified as bearer token -based. However, do consider you're not using bearer tokens as specified by the OAuth 2.0 related specs (see RFC 6750). That would imply relying on the Authorization HTTP header and using the Bearer authentication scheme.\n\nRegarding the use of the JWT to prevent CSRF: Without knowing exact details it's difficult to ascertain the validity of that practice. To be honest, it does not seem correct and/or worthwhile. The following article (Cookies vs Tokens: The Definitive Guide) may be a useful read on this subject, particularly the XSS and XSRF Protection section.\n\nOne final piece of advice. Even if you don't need to go full OAuth 2.0, I would strongly recommend on passing your access token within the Authorization header instead of going with custom headers. If they are really bearer tokens, follow the rules of RFC 6750. If not, you can always create a custom authentication scheme and still use that header."}, 4] | |

The Microsoft Excel home page will open.\n2. Search for an invoice template. Type invoice into the search bar at the top of the page, then press ↵ Enter to search for invoice templates. You must be connected to the Internet in order to search for templates.\n3. Select a template. Click a template that you want to use to open it in a window.\n4. Click Create. This button is to the right of the template's preview. Doing so will open the template in Microsoft Excel.\n5. Edit the template to fit your needs. For example, most templates have \"Company\" written across the top; you would replace this heading with your company's name. To edit text on the Excel document, double-click the text item, then remove the text item or replace it with your own.\n6. Fill out the invoice. Enter any information required by your invoice template to ensure that the final total matches what you're owed. For example, some invoice templates will require you to enter an hourly rate or a fixed charge. Most invoice templates use formulas to combine your entered hourly and the number of hours worked in the \"Final Total\" box.\n7. Save your invoice. Click File in the upper-left side of the page, click Save As, double-click a save location, enter your invoice's name, and click Save. This will save your customized invoice in your selected save location. Your invoice is now ready to be sent.\n\n\n## Use a template on mac\n\n1. Open Microsoft Excel. It's a green box with a white \"X\" on it. Excel will open.\n2. Click File. This menu item is in the top-left side of the page. A drop-down menu will appear below it.\n3. Click New from Template. It's an option in the File drop-down menu. Doing so opens a new page with template options.\n4. Search for an invoice template. Type invoice into the search bar in the top-right corner of the page, then press ⏎ Return. You must be connected to the Internet in order to search for templates.\n5. Select a template. Click a template to open a preview window with the template displayed.\n6. Click Open. It's in the preview window. This will open the invoice template as a new document.\n7. Edit the template to fit your needs. For example, most templates have \"Company\" written across the top; you would replace this heading with your company's name. To edit text on the Excel document, double-click the text item, then remove the text item or replace it with your own.\n8. Fill out the invoice. Enter any information required by your invoice template to ensure that the final total matches what you're owed. For example, some invoice templates will require you to enter an hourly rate or a fixed charge. Most invoice templates use formulas to combine your entered hourly and the number of hours worked in the \"Final Total\" box.\n9. Save your invoice. Click the File menu item, click Save As, enter a name for your invoice, and click Save. Your invoice is now ready to be sent.\n\n\n## Create an invoice manually\n\n1. Open Microsoft Excel. It's a green box with a white \"X\" on it. The Microsoft Excel home page will open.\n2. Click Blank Workbook. This option is in the upper-left side of the Excel home page. A blank spreadsheet will open. On Mac, skip this step if Excel opens to a blank document.\n3. Create the invoice heading. Your heading should include the following information:\n\t* \n\t* Company name - The name of the company to whom the invoice funds will be allocated. Descriptor - The word \"Invoice\" or a description of the type of invoice it is, such as \"Price Quote\" if you're quoting a price for your services to a client instead of billing for them. Date - The date on which you're writing the invoice. Number - The invoice number. You can either use a global numbering system for all your clients or individual numbering for each client. If you choose to number for each client, you can include the client name or a form of it in the invoice number, such as \"Westwood1.\"\n4. Enter the sender and recipient addresses. This information should appear near the top of the invoice, with your information above the client's. Your contact information should include your name, your company's address, a phone number, and an email address. Your client's information should include the company name, the name of the accounts payable person, and the client address. You can also include the client's phone and email address.\n5. Enter your billing information. You can devote a column to a short description of the product or service, a column to quantity, a column to unit price or rate, and a calculated column for the total price for the quantity purchased of that item.\n6. Display the amount of the total bill. This should appear below the calculated column of individual charges and can be generated with Excel's SUM function. For example: if you have $13 of work in cell B3 and $27 of work in B4, you might put the formula =SUM(B3,B4) in cell B5 to display $40 in that cell. If you used an hourly rate (e.g., $30) in cell B3 and a number of hours (e.g., 3) in B4, you would instead write =SUM(B3\\*B4) in cell B5.\n7. Include the terms of payment. This can appear either above or below the billing information. Common payment terms are \"Due on receipt,\" \"Due within 14 days,\" \"Due within 30 days,\" or \"Due within 60 days.\" You may also want to include a memo at the bottom of the invoice covering accepted methods of payment, general information, or a thank-you to your customer for shopping with you.\n8. Save your invoice. Use a name that will distinguish the invoice from other invoices you've sent to your client if necessary. To save your invoice:\n\t* \n\t* Windows - Click File in the upper-left side of the page, click Save As, double-click a save location, enter your invoice's name, and click Save. Mac - Click the File menu item, click Save As, enter a name for your invoice, and click Save.\n"}, 5] | |

For instance, there are $O(c^n)$ algorithms for Vertex Cover with $c huge improvement over the naive $\\Omega(2^n)$ and might make instance sizes relevant for you tractable.\n\n* Improve expected runtime\nUsing heuristics, you can often devise algorithms that are fast on many instances. If those include most that you meet in practice, you are golden. Examples are SAT for which quite involved solvers exist, and the Simplex algorithm (which solves a polynomial problem, but still). One basic technique that is often helpful is branch and bound.\n\n* Restrict the problem\nIf you can make more assumptions on your inputs, the problem may become easy.\n\n* Structural properties\nYour inputs may have properties that simplify solving the problem, e.g. planarity, bipartiteness or missing a minor for graphs. See here for some examples of graph classes for which CLIQUE is easy. \n\n* Bounding functions of the input\nAnother thing to look at is parameterised complexity; some problems are solvable in time $O(2^kn^m)$ for $k$ some instance parameter (maximum node degree, maximum edge weight, ...) and $m$ constant. If you can bound $k$ by a polylogarithmic function in $n$ in your setting, you get polynomial algorithms. Saeed Amiri gives details in his answer.\n\n* Bounding input quantities\nFurthermore, some problems admit algorithms that run in pseudo-polynomial time, that is their runtime is bounded by a polynomial function in a number that is part of the input; the naive primality check is an example. This means that if the quantities encoded in your instances have reasonable size, you might have simple algorithms that behave well for you.\n\n* Weaken the result\nThis means that you tolerate errorneous or incomplete results. There are two main flavors:\n\n* Probabilistic algorithms\nYou only get the correct result with some probability. There are some variants, most notable Monte-Carlo and Las-Vegas algorithms. A famous example is the Miller-Rabin primality test.\n\n* Approximation algorithms\nYou no longer look for optimal solutions but almost optimal ones. Some algorithms admit relative (\"no worse than double the optimum\"), others absolute (\"no worse than $5$ plus the optimum\") bounds on the error. For many problems it is open how well they can be approximated. There are some that can be approximated arbitrarily well in polynomial time, while others are known to not allow that; check the theory of polynomial-time approximation schemes.\n\nRefer to Algorithmics for Hard Problems by Hromkovič for a thorough treatment.\n* Simplicity is beauty: Improved upper bounds for vertex cover by Chen Jianer, Iyad A.

| [{"Instruction": "Explain why Android wipes data when unlocking bootloader", "Response": "It's a security concern. The Android documentation doesn't provide a lot of elaboration, stating simply:\n\n The procedure must be confirmed on-screen, and deletes the user data for privacy reasons.\n\nHowever, the privacy concern is relatively straightforward to extrapolate. Once the bootloader is unlocked, the device can be flashed with unsigned images. This means that it is relatively trivial to root the device, and there are actually multiple ways it can be done, such as:\n\n* Flashing a system image with root tools built in\n* Flashing a boot image that runs ```adbd``` with root by default (an \"unsecure\" image)\n* Flashing a recovery image, then using that to overwrite the system or boot partitions with ones that allow root access\n\nOnce root is obtained, all of the information on ```/data``` essentially becomes accessible. This could be emails, contact information, or many other pieces of personal information that you likely don't want in the wrong hands. \n\nTherefore, it makes sense to wipe all of this data during the unlocking procedure to ensure that there is no off-the-shelf \"official\" way of bypassing the sandboxing restrictions implemented by the Android operating system, which would thereby allow someone to steal personal data.\n\nOf course, there may be ways to root without wiping on some devices, but they rely on exploits rather than official methods like a bootloader unlock, meaning they are basically bugs."}, 5] | |
