Some time ago I watched these video casts, and I liked how the project was managed. Is there a tool for linux similar to target process (target process's webpage)? If not, what tool are you using for managing an agile project (linux, or cross platform)? Thanks
All file systems I've encountered have been based on folders - you have a root folder, which contains files and subfolders, which in turn contains files and subfolders, and so on. Is there a better alternative to organizing files, and will it replaced the current system any time soon? Feel free to include some history ...
I am looking for advice of where to deploy a Rails app for a small business: web-based https needed fewer than 500 users (probably) fewer than 20 concurrent users So far, I am reading pricing information of: Amazon EC2 Dreamhost VPS Heroku Self-hosting (most unlikely) Any suggestions and/or pros and cons to share? ...
I've been involved in several projects either as tester or developer. In many of projects there were following statuses for defects: WON'T FIX Cancelled Do you use such statuses and how do you differ them? I ask, because most people can't explain the difference. My understanding is: WON'T FIX - developer will not fi...
I write all (well, most) of my programs in an IDE, mostly it's netbeans. Should I just use Mercurial through the IDE, or is it better if I used the CLI instead? and why?
After reading some Python material and seeing some Python code a few years back I decided to give it a whirl. I decided to start with Python to solve the problems on Project Euler and was throughly impressed with the language. Since then I've went on to learn Django, and now use it primarily for my web applications. ...
This is probably a totally noob question but I have missing links in my mind when thinking about linking libraries in iOS. I usually just add a new library that's been cross compiled and set the build and linker paths without really know what I'm doing. I'm hoping someone can help me fill in some gaps. Let's take the O...
I remember reading somewhere that the original concepts behind OO were to find a better architecture for handling the messaging of data between multiple systems in a way that protected the state of that data. Now that is probably a poor paraphrase, but it made me wonder if there is a way of teaching OO without the (Bik...
There are several examples of packaging where an application package is built, named, described, even licensed, but contains only setup code and dependencies -- it has no first-class runtime software of its own. I would call this "meta-packaging". This seems to be particularly popular in the open-source world, includin...
I have a degree in computer science. It has been great for opening doors, getting a job. As far as helping me in the professional field of C# .NET programming (the most popular platform and language in the area I work if not the entire united states on hands down the most popular OS in the world) its hardly useful. ...
I've noticed since installing Visual Studio 2010 SP1 that I'm having huge performance issues. It will randomly freeze up on me quite a bit. I had no performance issues with Visual Studio 2010 before the upgrade. The only add-on I have running is ReSharper. I'm wondering if anyone else is experiencing performance issues...
I have not yet heard about any uses of a logical programming language (such as Prolog) in the software industry, nor do I know of usage of it in hobby programming or open source projects. It (Prolog) is used as an academic language to some extent, though (why is it used in academia?). This makes me wonder, why should y...
For example, some library (in my case it's ruby gem) became deprecated. And my app is using this library. It's ok and I have not any problems with how it works. When should I switch from deprecated open-source library to something new? Or should I at all?
Has anyone ever tried creating a complete code documentation first, before actually writing the code? I was thinking about this earlier because I thought it would help to write a concrete interface and would make sure your initial design wasn't floored by making you think about how classes interact. Is this a good idea...
Who wants to work in a fast-paced environment? Not me! I want a civilized environment where people have a sense of balance. Higher quality work gets done that way and work life isn't full of stress and anguish.
How to for non-programmer : formulate web-programming requirements for designing a website by a third party how to ask and what to ask Example : I want to hire someone to design or implement any existing " Photo Voting Contest " with some extra features. How do I formulate my needs for a web-programmer to understand...
We are currently hiring a junior developer to help me out, as I have more projects than I can currently manage. I have never hired anyone who wasn't a friend or at least an acquaintance. I have a phone interview with the only applicant that actually stood out to me (on paper), but I have never done this before. Our pro...
I am a non-programmer that has used the services of : freelancer, odesk, etc I've tried asking for what i need but, I can't find anyone who can show me any type of example similar to what I request in the specs for the web-programming. They have front ends and back ends, but they don't fulfill true "live" website requ...
Imagine a project where the interface to be delivered has been locked down 90%, and you are already in possession of a solid architectural design. Would an agile methodology still offer any value in this situation? It seems to me that agile methodologies (and I'm thinking Scrum), offer most value where there is a high...
Do you do any performance testing in any repeatable and automated way? Do you trigger it as a part of CI builds? What tools do you use? How do you spot changes in trends? I'm looking for how-tos and description of working set-ups for end-to-end automated performance testing approaches.
I was asked this in an interview, and I'm not sure what the answer is or how to approach the problem. Find a pair of numbers that sum up to zero (or any other number), then find three (and then four) numbers that sum up to zero.
I need to write a simple file transfer mechanism (that isn't ftp). Firstly, it must have a GUI. Secondly, it must not be dropbox. Third, it may not use any paid libraries, and hopefully, it uses open source components. The question that came to my mind is, where is everyone moving, from desktop to web, or from web to d...
Are languages which are very customizable, like Python (see for example goto in Python, lightweight Python type-checking) and Javascript (see jQuery for one example of this) more widely used than languages which cannot be customized very much?
If I read through the source code of programs in the similar field of application like the one I am working on (e.g.: 3D car racing simulation), and find some techniques or patterns they use better than the ones I am using, and use those in my project - is it theft? (No source code would be directly copied in any way.)...
Every shop I've worked at we have followed what I thought was a standard hiring sequence: Solicit resumes Phone screen applicants we are interested in In-person interview In some shops, second in-person interview (just w/ CEO for example) Most places I apply to follow something along these lines. But some shops want ...
Sucking Less Every Year -Jeff Atwood I had come across this insightful article.Quoting directly from the post I've often thought that sucking less every year is how humble programmers improve. You should be unhappy with code you wrote a year ago. If you aren't, that means either A) you haven't learned anyth...
Our company ships a range of desktop products for Windows and lots of Linux users complain on forums that we should have been written versions of our products for Linux years ago and the reason why we don't do that is we're a greedy corporation all our technical specialists are underqualified idiots Our average produ...
Are dedicated hosting yet cheaper and would remain so ? Do they really going to survive as cloud based offering are also getting cheaper day by day ? I am asking to gain perspective of long term scenario in hosting space as well as to know what is the current situation. Everywhere I go there is this buzzword "cloud" a...
I want to understand the correct use and implementation of hash tables in php (sorry). I read somewhere that an in-experienced programmer created a hash table and then iterated through it. Now, I understand why that is wrong but I haven't quite got the full knowledge to know if my understanding is correct (if you know...
When first implementing Scrum within a team, how should you go about determining the amount of story points that are in an initial sprint when you have no idea of the team's velocity? Should you base this on an estimate of hours and only use the points at a later stage?
One can often hear that OOP naturally corresponds to the way people think about the world. But I would strongly disagree with this statement: We (or at least I) conceptualize the world in terms of relationships between things we encounter, but the focus of OOP is designing individual classes and their hierarchies. Note...
In your experience (anecdotal or otherwise), what are some effective ways to introduce Agile into a non-Agile organization or company? UPDATED: Can anyone speak to cases where you tried to introduce Agile but you were "shot down"? Also, do you now have a retrospective understanding why you were "shot down"?
I have been frequently asked questions like "Rate yourself in java" It goes like interviewer : Rate yourself in java on the scale of 10 me: 9 interviewer : Rate yourself in J2EE me : 8 .... But really I just come up with arbitrary numbers. Sure I know Java well , but what does it mean to say "9 out of 10" . I think it...
I have an object containing the results of a computation. This computation is performed in a function which accepts an input object and returns the result object. The result object has a print method. This print method must print out the results, but in order to perform this operation I need the original input object. ...
I am currently working on ms build to publish my winform application based on the environment selected (Dev or Prod). I am using Ms Build Community Task and referencing this article to achieve this purpose. I had a few theoretical doubts based on publishing application. 1) Is there any difference in publishing through ...
I just wondered if anyone had any tricks or programs they used when comparing two of the same file but different versions? I appear to have foolishly made a modification at some point today (Went a few hours without running any tests) and it has stopped the whole project working - without throwing up any errors so it m...
I'm looking for some small programming projects that I can give potential employees to gauge their programming abilities. These will be programmers straight out of college. I'm looking for projects that would take someone a couple of hours and they would email back their answers post-interview. One example would be to ...
Some of my recent clients are asking for remote connections to the office server, for standalone work, etc, in winForm applications. Since the concept of the web is remote connection to a server both of data and resources, it should be possible to place both of this in cloud and have the winForm apps connect to it as i...
People want SOAP or a WDSL. I've just got a defined API. What's wrong with that?
I began coding in in Python primarily where there is no type safety, then moved to C# and Java where there is. I found that I could work a bit more quickly and with less headaches in Python, but then again, my C# and Java apps are at much higher level of complexity so I have never given Python a true stress test I supp...
My company is a sub contractor on a major government contract. Over the past 5 years we've been developing in house applications to help support our company and streamline our work. Apparently in 2008 our president of the company at that time signed a continuation of services contract with the company we subcontract ...
We have been developing a web application in ASP.NET MVC. We have scenarios where many actions on web page are dependent upon role of a specific user. For example a memo page has actions of edit, forward, approve, flag etc. These actions are granted to different roles and may be revoked at some later stage. What is th...
I sometimes hear about pain points of customers using our app from sales people, but there really isn't a good way for us to currently keep track of these. I was going to write one myself but figured I would ask first. I was thinking something so simple it would literally just be a small form for adding a new feature, ...
I've seen a bunch of sites that benchmark new hardware on gaming performance, zipping some files, encoding a movie, or whatever. Are there any that test the impact of new hardware (like SSDs, new CPUs, RAM speeds, or whatever) on compile and link speeds, either linux or windows? It'd be really good to find out what mat...
Let's assume that someone buys "off the shelf" a Social Network (License) with all the core social network features needed, for a one off payment of 500$, and then a renewal fee of 250$ per each following year (of continued use). Then, the inhouse graphic designers and web developers modify the webpages (template) layo...
I spend a lot of time working on projects in which I am the sole developer, project manager, designer, QT person (Yes, I know... Bad!), and sometimes I'm even the client. I've tried just about everything for planning projects and managing myself, from just sitting and working freestyle until the project is done howev...
Many of us have worked in multiple environments over the years, and have found that some are more productive than others. In many cases, it's not directly related to the abilities of the developers, but instead to their environment. I myself have experienced this, being in places where I seemed to develop faster, and b...
While writing the code or during design do you try to generalize the problem at the first instance itself or try to solve that very specific problem. I am asking this because trying to generalize the problem tends to complicate the things (which may not be necessary) and on the other hand it will be very difficult to e...
I'm prone to building centralized classes that manage the other classes in my designs. It doesn't store everything itself, but most data requests would go to the "manager" first. While looking at an answer to this question I noticed the term "God Object". Wikipedia lists it as an antipattern, understandably. Where is t...
The more I explore Github, the more I like it. I really enjoy how coding is becoming more social. I'm curious as to if there are any bad practices that programmers should avoid in sharing their code with each other. And in naming bad practices, what are the best practices for code sharing? For example: Is it a bad pra...
I just started reading about spring , and a book mentioned "Spring AOP is a Proxy based framework" . What is meant by "Proxy based" framework.
I've read that I should avoid the postfix increment operator because of performance reasons (in certain cases). But doesn't this affect code readability? In my opinion: for(int i = 0; i < 42; i++); /* i will never equal 42! / Looks better than: for(int i = 0; i < 42; ++i); / i will never equal 42! */ But th...
For example if we consider ActionScript2.0(based on Objects but programming does not implement much OOP ) vs 3.0(highly OOP) its like a whole new scripting language in the sense of approach, programming style,features you get the idea. In PHP we can see current versions going from 3-5. brief version changes Question ...
I'm a Microsoft developer mainly, but there are a couple of small-ish projects I'd like to fiddle with which would benefit from being cross platform. The platforms I want to target are: Windows, Linux, Mac, Android and preferably iPhone, web (running in a browser). I need 3D (Around the level of support seen in someth...
From reading the descriptions, I understand that in TDD tests are done prior to writing the function and in Unit Testing, its done afterwards. Is this the main difference, or the two terms can't even be compared as such. Perhaps, Unit Testing is an integrated part of TDD.
In college it is taught how you can do math problems which use the ++ or -- operators on some variable referenced in the equation such that the result of the equation would yield different results if you switched the operator from postfix to prefix or vice versa. Are there any real world applications of using postfix o...
The general meaning of "cross-functional team" is a team which combines specialists in different fields that are required to reach the goal. But it looks like in Agile cross-functionality means not only combining different specialists, but making them mix. Henrik Kniberg defines cross-functional team this way: "Cross-...
I've started doing some research on the technologies that I will need for my website. I'm trying to implement a really simple website with OpenID user registration. The website will store a block of text for each user. I imagine this means that I will need a database with: User ID Open ID url Data Having said that, ...
I am starting to learn Scheme by the SICP videos, and I would like to move to Common Lisp next. The language seems very interesting, and most of the people writings books on it advocate that it has unequaled expressive power. CL seems to have a decent standard library. Why is not Lisp more widespread? If it is really t...
There seems to be a long-held belief (mainly by non-lispers) that lisp is better than most languages at AI. Where did this belief originate? And is there any basis in fact to it?
A lot of the basic network protocols that make up the infrastructure of the Internet are built in to most major Operating Systems. For example, TCP, UDP, and DNS are all built into Linux, UNIX and Windows, and are made available to the programmer through low-level system APIs. But when it comes to SSL or TLS, one ha...
I am about to start a new project (a game, but thats unimportant). The basic idea is in my head but not all the details. I don't want to start programming without planning, but I am seriously fighting my urge to just do it. I want some planning before to prevent refactoring the whole app just because a new feature I co...
When developing web applications, how does one keep local files and remote files synced together? There is the obvious way, whenever you edit a file on your local machine, just upload that file to the remote machine. Is there a more efficient way? I ask because I have been using subversion control, and it is so easy to...
I'm a student working on my B.E(CS) and my question is the following: Is testing in the software field needed? If we create a software with great care, then why should we test? After testing can we be sure that we have achieved this goal (the product/software works as intended) because we have done the testing for...
What is an appropriate UML diagram if I want to display how user request web page, enters some data, then posts the form (and if the validation has not succeeded, user is redirected back to requested web page)?
What is the difference between people like Zukerberg, Page and Brin who are programmers and also extraordinarily successful financially, and the other wise great programmer who are not very much financially successful (like most of the employees at facebook and google).
Sorry for the confusing title. Let me explain: I am currently trying to get a site developed. My current developer has taken the site about as far as I think they are capable of and I am planning on hiring another developer to put the finishing touches on it, debug it and upgrade some of the more technical details. T...
I have been given a task of finding the permutations of the letters of a given word. For example, if the given word is like then possible answers are liek, lkie, and so on. This can be implemented in any language, but the rule is not to use any built-in functions/API to find the combinations. We know that design patter...
I have an idea on how to revamp our internal application, after having accessed the needs of the users, addressing thier current issues, and the like. But I am not a coder. My last application I wrote was in college, in C, (java wasn't invented-ish!) and it was a booking system, with the option to add on other modules,...
I'm considering freelancing via eLance.com (or another similar site) to help pay the bills while developing games (that will eventually pay the bills). What's working through elance like? Any recommendations or strategies? Any feedback is appreciated.
Last week, I was just viewing this amazing interview by Kevin Rose of Phillip Rosedale, of Second Life. And they had an amazing discussion about how to find, hire and identify good programmer's, and how hard it is to find good ones. Which has lead me to really think about the way we programmer's learn, are taught. For...
In at least the web development field, web servers are everywhere but are backed by very few database servers. As web servers get hit with requests they execute large queries on the database, putting the server under heavy load. While web servers are very easy to scale, db servers are much harder (at least from what I ...
I have been programming for 6 years and I am in high school (I prefer not to disclose my age). I have dabbled in many different languages. Just to list a few: Java, PHP, C++, Python, Autohotkey, Mathematica and many more. I have a very good understanding of the basics of general programming. The only problem is I still...
Sometimes you need to write a constructor which can fail. For instance, say I want to instantiate an object with a file path, something like obj = new Object("/home/user/foo_file") As long as the path points to an appropriate file everything's fine. But if the string is not a valid path things should break. But how? ...
I saw an interesting conversation on here about airline reservation systems and the services that connect them (like Sabre). This is an almost identical analog to a problem I've been trying to figure out and I'm looking for the fundamental components required to build a service like Sabre (no this isn't a competing ser...
I have seen a lot of different project organizations in different tertiary sector businesses, but I have never felt that IT R&D projects were well organized. I understand that R&D projects need flexibility, and less time-constraints to give free rein to innovation. My guess is R&D projects organization needs to be rev...
Any and all advantages/disadvantages would be appreciated!
I am implementing a gossip based membership detection mechanism. Lets say we have a ring topology, i.e. node1 only knows about the 2 nodes (node4 and node2) around it. node1 - - - - node4 node2 - - - ...
Programming languages are formal languages, but unlike many formalisms, they also have certain inherent meaning defined by their operational semantics, or, in the case of markup languages, presentation semantics. And programming languages, though indeed formal, are very similar to natural languages, in terms of the com...
As the Haskell Wiki itself states: There is a large number of GUI libraries for Haskell. Unfortunately there is no standard one and all are more or less incomplete. In general, low-level veneers are going well, but they are low level. High-level abstractions are pretty experimental. There is a need for a supported me...
I'm in the job market and I have a set of priorities for my next job including salary, line of business, etc. One thing that is nowhere on my list of requirements however, is the development process methodology. I feel my job is to create software and I view the process structure as something I can adapt to whether it'...
Does anyone have any tips, thoughts, warnings, or general wisdom for a application/database developer who is moving specifically from a start-up sized company to a large organization? Examples thoughts would include things such as: How might I interact differently with the management chain? Do you see trends in qualit...
I have use github for a while, but my project is only one developer -- myself. I want to get some contribute from others, and some of my friends said they can give me some patch, but we all don't know how to use github as a tool for us. And I know that github will also help project get more contribute from the open sou...
I am a project manager at my company. I work with a few teams of developers using a standard, well-known version control system known as CVS. I'd like to see continuous integration and automated builds implemented to help prevent problems with the build breaking and with bad deployments sneaking onto the production s...
I've read somewhere that it's a bad idea to name classes after verbs (manager/browser/editor) but what's the proper name for manager/browser/editor? EDIT: the problem is that system could turn in a big ball of "services" - tiny objects which does something specific and does not contain any data - which is bad (at least...
I have a distributed data collection system where I have first layer as regional Databases where all collected data is initially stored and master database where all the data is consolidated, what are you thoughts on schema design of this situation, also important thing here is I could have overlapping Ids and dictiona...
When I was studying in the university I often heard the idea that Fortran compilers produced faster code than C compilers for an equivalent program. The key reasoning went like this: a Fortran compiler emits on average 1,1 processor instruction per line of code, while a C compiler emits on average 1,6 processor instruc...
Is functional programming so related to mathematics because much of the functional programming is depicted with mathematical notions? Is it a MUST to have a strong base of maths to learn & understand functional programming for a programmer with a imperative background?
We have a few interns here that have orders from college to integrate speaking, reading, and writing French into their internship. All of them are working on developing their own web application, and I'm wondering how we can integrate French into their projects. Here are some things I've come up with: Translate the wh...
we have multiple clients with different needs. Although our software is modularized to a degree, it's almost certain that we need to adjust every module's business logic here and there a little for each customer. The changes are probably too tiny to justify splitting the module into a distinct (physical) module for eac...
I understand that whenever you upload a new app, you can set the copyright name for the app. Where is this name displayed? Is this name displayed underneath the name of the app when searching in the app store? Or is that the seller name that you specify when you upload your first app?
I'm busy working for my thesis about Web Development Frameworks. I want to write about frameworks that have been used in the past and frameworks that have a good chance of lasting in the future, such as JQuery and PrimeFaces for example. I also want to do a survey and I am looking for good questions to ask on this surv...
The other day, in our PHP class, our teacher gave us a challenge used by a friend of his in job interviews. It works in every programming language, so it's not limited to PHP. He said that his friend uses this 'riddle' to weed out the people who can't think of a fast answer when it comes to logical challenges. The peop...
Which programming language first introduced 'Hello World' as a first program to code for beginners?
Let's say you get stuck on an solution for a while. What do you do? How do you get it solved? What is the best way to not feel frustated?
I felt this is the best place to ask this, rather than Stackoverflow as it is not related to programming. Ok. The thing is I need to draw an ERD of a leave management system. Suppose there are three level of user roles there - Level A, B and C. Where A can manage both B and C; B can manage only C and C is normal users....
I've been experimenting recently with Android applications. I've developed the convention (which I've seen used elsewhere) of placing my unit tests in a parallel source folder within an Eclipse project. This works well because the Eclipse JUnit runner can find the tests easily and the project with it's tests are nicely...
Well, I have a certain dispute with a colleague of mine. We have a software design where we build all of our widgets server side and send them client side as html. Most of the time it's better and easier to control and add stuff to. But sometimes it just is not that good; it makes the client side act "retarded" regardi...
I have a project that requires me to control movement of SCARA robot using VC. I am a beginner in programming so I thought of using existing program as my reference. The SCARA robot that I am using is regarded as a valuable property of the department and must be operated with extra care. I cannot simply make a program ...
...or are things getting more complicated? It seems to me that you need to know a lot of stuff to 'properly' develop an MS web app these days. In the bad old days when we didn't know any better we had database tables, ASP.NET, ADO.NET and you constructed a web app using relatively simple concepts. These days there see...
