What will happen to the portions of the Boost library that are incorporated into the new C++ standard? Will they continue to evolve and any changes be reincorporated into the standard which follows C++0x?
This is a more specific question (or actually two, but they are related) coming from the comments of OOP technology death where someone stated that OOP is not the right paradigm for GUI programming. Reading the comments there and here I still have the feeling there are things to learn: which programming paradigms are ...
C#'s lambda expression also has closures but is rarely discussed by the C# communities or books. I see far more JavaScript people and books talk about its closures than they do in the C# world. Why is that?
From Wikipedia Extensible Markup Language (XML) is a set of rules for encoding documents in machine-readable form. It is defined in the XML 1.0 Specification[4] produced by the W3C, and several other related specifications, all gratis open standards.[5] What are the historical reasons for calling the shorthand XML ra...
I always hear that involving with open source projects is good for career and the more (good) open source you release, the closer you will be to getting your dream job before you've even had an interview.I am expert in Java and I am trying to become fluent in Scala. I always think about getting involved in open source ...

One problem I have with compiler optimization is, that I actually never know what the compiler (or in this particular case the Jit) does with my code. So is there any possibility for me to know whether a particular compiler optimization took place or not? I just want to be sure about that some objects (math vectors) ar...
In DDD i struggle to understand whether or not my domain is split correctly into aggregate roots and then those aggregate roots are grouped correctly into bounded contexts. is there a way - like a set of rules/guidance i can use to decide whether or not i am placing things in the right AR/BC
I always wonder this, and perhaps I need a good history lesson on programming languages. But since most compilers nowadays are made in C, how were the very first compilers made (AKA before C) or were all the languages just interpreted? With that being said, I still don't understand how even the first assembly language ...
I had a small project that I was doing on the side. It was basically a couple of forms linked to a DB. Access was out, because it was a specifically meant to be a web application. Being a small project I used ASP.NET Dynamic Data, but, for various reasons, the project ended before deployment. I met the client recently,...
I have seen some developers use hosted scripts to link their libraries. cdn.jquerytools.org is one example. I have also seen people complain that a hosted script link has been hijacked. How safe is using hosted scripts in reality? Are the scripts automatically updated? For example, if jQuery 5 goes to 6 do I automatic...
I work with someone who, every time they call a function they put the arguments on a new line e.g. aFunction( byte1, short1, int1, int2, int3, int4, int5 ) ; I find this very annoying as it means the code isn't very compact, so I have to scan up and down more to actually make any sense of ...
I am in the process of finally rolling Mercurial as our version control system at work. This is a huge deal for everyone as, shockingly, they have never used a VCS. After months of putting the bug in management's ears, they finally saw the light and now realise how much better it is than working with a network of share...
I would like to switch from a 5 day week to a 4 day, but maintain a 40 hour working week. Would the 10 hour days affect your ability to be productive? I hate our public transit system so if I could reduce my transportation by 20% I would be happy. If other developers who work 10 hours shifts could be clear as the their...
I have a interface in our code base that I would like to be able to mock out for unit testing. I am writing a test implementation to allow the individual tests to be able to override the specific methods they are concerned with rather than implementing every method. I've run into a quandary over how the test implementa...
I have a Linux application I've developed, and I have created a standalone VMWare Image that people can download to try out the application without needing to install and configure a Linux Server. I created this VMWare Image by starting with a base Debian system, installing a bunch of packages and then configuring all ...
I am working on an app which I would dearly love to transition from a fairly traditional layered architecture to CQRS, for a number of reasons, not least fo which is that having a robust event log will make adding a couple of feature requests I can see barrelling towards me trivial to accomodate. Now, I have a conceptu...
I'm learning C++ and I'm using g++ on Linux for practicing. I want to know if people working as programmers use g++ -pedantic flag and also its importance in real world. What about other compilers, do they also allow this? Has this become some de-facto standard? I'm interested because I'm reading C++ Primer where th...
SO I'm about to put together a new site and I'd like to go about it by making a web application that parses /#!/ url's and requests content accordingly via AJAX calls to a JSON API that is already put together. My questions are... What are the best practices concerning #! url's Are there any good JavaScript libraries ...
I used to work on a really small outsourcing company (4 programmers and the boss), then when the stress and the frequent long shifts made the situation unbearable I made the switch to a better paid job with a more relaxed schedule that allows me some more free time. The problem, however, is that for the most part, ever...
Is it possible to take a binary compiled for ARMv7 architecture and convert it to ARMv6 ? Are there any tools that can do this?
I think I am at a point where I can truly contribute to a Ruby open source project, can you suggest one or more that would be open to having a true beginner contribute. This would be my first group project where I would like to be 'mentored' or something similar by a more experienced coder. I would be able to work in m...
When releasing a software update, how detailed should the notes be? Specifically, how detailed should bug fixes be?
I want to say that my program is capable of splitting some work across multiple CPU cores on a single system. What is the simple term for this? It's not multi-threaded, because that doesn't automatically imply that the threads run in parallel. It's not multi-process, because multiprocessing seems to be a property of a ...
Looking at most (if not all) dynamic languages (e.g. Python, PHP, Perl and Ruby), they are all interpreted. Correct me if I'm wrong. Is there any example of dynamic language that goes through compilation phase? Is dynamic language identical with interpreted language?
As far as I know and have understood in my experience with Qt, it's a very good and easy to learn library. It has a very well designed API and is cross-platform, and these are just two of the many features that make it attractive. I'm interested to know why more programmers don't use Qt. Is there a deficiency which spe...
Jeff Atwood recently wrote a blog post about Netflix's implementation of a "Chaos Monkey". It is a very high level article. I am curious if anyone has actually implemented this technique for testing a system. I guess what Im really trying to ask is: What strategies do you implement to ensure your architecture can surv...
I've been having a discussion about licensing and open source software. Basically - the other guy is saying that licensing is easy, if you're going to build a product you can use an (any) open source project and make money by selling that code. My issue is that say I create a website or app with a project that uses a G...
I am an MCA fresher and will be working on dot Net for next few months (almost 10-12 months). After that I want to switch over to Java. How is the possibility that I can switch over to it?

We have been working with BDD for sometime now and one issue that keeps cropping up is related to the scope of our scenarios. Particularly when it come to making a change to existing functionality. As a developer I see the scenarios as being akin to a spec, ie. this is the change that is required. However often they se...
I started programming in C++ at uni and loved it. In the next term we changed to VB6 and I hated it. I could not tell what was going on, you drag a button to a form and the ide writes the code for you. While I hated the way VB functioned I cannot argue that it was faster and easier than doing the same thing in C++ s...
So I just got a copy of ArgoUML. I originally thought I'd be able to just play around with it to learn it, but it's turning out to be extremely difficult. I searched online for tutorials and videos but came up with nothing useful. The help file for ArgoUML is very incomplete as well. Does anybody know of any online r...
You can often hear that programmers should learn many different languages to improve themselves. I still go to school and don't have big programming experience (a little more than year). But what was noble intention to improve programming skills turned into some kind of OCD: I feel that I won't calm down until I learn ...
I have a project that uses GNU autotools to build itself. I am trying to modify so that autotools generates all the non-versioned control files in a separate directory so that I can keep the source tree clean of temporary files. Anyone has any ideas how to do this ?
I am torn between learning myself some Powershell or just leveraging my existing Ruby knowledge for the various Windows scripting things that I do from time to time. Powershell does look incredibly powerful, but from initial impressions the syntax is fairly ugly. Is there anything that Powershell can do that I couldn't...
At a recent UI/UX MeetUp that I attended, I gave some feedback on a website that used Javascript (jQuery) for its interaction and UI - it was fairly simple animations and manipulation, but the performance on a decent computer was horrific. It actually reminded me of a lot of sites/programs that I've seen with the same ...
I'm very tempted to use it purely because of its neat Binding APIs, and now that you're able to use it in conjunction with Swing it feels like a natural progression. The only thing that I can seem its lacking off the bat is a GUI builder (But then according to who you speak to, this isn't necessarily a bad thing!) Does...
I manage a team of coders (5 people) that maintain a few modules in a large project. On top of doing coding, we also do production operational tasks (like doing server housekeeping, batch backlog tracking). These tasks are done daily, done by one person, and is rotated weekly. The problem is this: These tasks are routi...
I'm looking to get started with objects in my unit tests. It seems there are tons of good mocking frameworks out there. Do the different frameworks have different target audiences? What factors should I consider when choosing which framework is right for my situation?
Laugh if you want, but I used to develop substantial line-of-business applications in VB6, long before the .NET framework came along. Why, when I was your age, we used to walk two miles in the snow, uphill. Both ways... Love it or hate it, VB6 had a REPL-like feel, and a very rapid development cycle. I would like to...
I have been programming for many years now, primarily in PHP and the like and would consider myself an intermediate programmer. Some of my online projects have now gone global and very widely used, i am now in deep thought about scalability etc. All of my systems so far are written in PHP, no known database structure s...
As a learning C++ programmer, I am trying to select a GUI framework or library for my own projects. I have some experience with Qt: it's very straightforward, it has a very good documentation, and provides a lot of tools, but it seems to duplicate a lot of the standard library. Are all C++ GUI libraries like this? What...
In the Handling my antiquated coworker question, various people discussed strategies for dealing with coworkers who are unwilling to integrate their workflow with the team's. I'd like, if possible, to learn some strategies for "teaching" a coworker who is merely ignorant of modern techniques and tools, and possibly a l...
Have a tree of variable depth, and width. What is the best algorithm to find the next occurence of the node in that tree. Next = Search to the right side of the tree ( as in breadth first search ) The selection criteria for the next occurrence of the tree is changeable in different situations. For example, at one plac...
For example: We're running a two community sites on two domains (call them example.com and example.net). We want to be able to expand that to more domains later. We want to allow multiple types of login (OpenID, Facebook, Twitter, standard username/password). We want someone who's logged into one site to automatically...
I have been reading about various Flex frame works, Robot Legs, Swiz, Cairgnom (spelling error) and a few others. What I am missing is how they actually work with Flex / Flash Builder. Are they simply libraries that you can use with the Flash Builder IDE? Why should I learn to use one of them instead of just using the ...
I need to design a class hierarchy for my C# project. Basically, class' functionalities are similar to WinForms classes so let's take WinForms toolkit as an example. (However, I can't use WinForms or WPF.) There are some core properties and functionalities that every class needs to provide. Dimensions, position, color...
Lately I've used this technique a few times, and I'm trying to figure out if it has a name, if it's one of the patterns, etc. In complicated situations where I might normally have a number of giant select case statements, I've been experimenting with a more plugin-style approach. I create an interface, let's called it...
I am using Ruby on Rails 3.0.7 and I would like to learn to write "advanced" plugins for the current versione of the framework. In order to do that I would like to buy some books but what I have seen on the Amazon website are two or three year old... Do you know and\or advice some books for this matter? P.S.: Also link...
I work on several git repositories though on most not more than 2 people work. Mostly me and my boss. Very often when we work in parallel it happens that "git log" doesn't look so nice because of the merge commits. My boss always complains about that. I really hate that fact because this makes me effectively serialize ...
I'm a professional .NET -C#- developer who's interested in doing development for Android. I'd like to know if it's really necessary for me to first read a book or two on Java (like Java For Programmers 2nd), or if I should just be able to pick up an Android book (like Pro Android 3) and be able to -mostly- work my way ...
In a financial services environment - is it realistic to ask your team of ten programmers to take on a 100% automated unit and integration test coverage goal as a stretch task for a legacy java system (>1.5M SLOC)? [as a two year goal in increments]
The title says it all but here's some explanation of what I want to know: Let's suppose a programmer has around 5 years of experience in multiple, mainstream languages. Also suppose that the programmer has worked in different positions from junior developer to senior s/w engineer to a team lead. How would he know this ...
I am an iOS developer. I have read about unit testing and how it is used to test specific pieces of your code. A very quick example has to do with processing JSON data onto a database. The unit test reads a file from the project bundle and executes the method that is in charge of processing JSON data. But I dont get ho...
I am refactoring a PHP OOP legacy website. I am so tempted to start using 'final' on classes to "make it explicit that the class is currently not extended by anything". This might save lots of time if I come to a class and I am wondering if I can rename/delete/modify a protected property or method. If I really want t...
There is a module in our telecoms equipment which is written in C. I think the code in this module has a bad smell because it has a number of symptoms: When new features are added to this module, some original features go wrong. And some weird problems were finally orientated to the buffer overflow of this module. It ...
I am developing an OS reporting system for PHP, it's main emphasis is right now on the server side of things. I am trying to look for examples of good UIs for reporting systems. The problem: there are dozens of reports, each linked to the other, how do you navigate between them? How do you know the path you took to get...
I have a good breadth of experience now (over a dozen) primarily as a dba,developer, BI admin, data analyst. I started my career in a couple of startups and now for a big internet company. The culture has always been interesting, fast-paced and just constantly moving. Recently, a family member of mine asked if I would ...
in school we are taught how we can balance an AVL tree upon an insertion or deleting. How is this type of knowledge actually going to be useful in the real world? Can someone give an example on when this type of knowledge would actually be useful? From what I have seen, in the workplace such details hardly ever come u...
I'd like to begin my question by saying that I understand that SCRUM or some derivative of it is probably a good way to go for managing software development. It seems all the big companies and my managers use it or have used it, and I can't really argue with all that experience. However I'm struggling to understand t...
At our company we have a team working on 3 different projects at the same time, where typically only one or two people are involved in each project. Project work often involves mastering new technologies and or solving bugs, both leading to tasks which are very hard to estimate. In this situation, the management still ...
It seems that conventional wisdom suggests that good programmers are also good at math. Or that the two are somehow intrinsically linked. Many programming books I have read provide many examples that are solutions to math problems, or are somehow related to math as if these examples are what make sense to most people. ...
As one of my summer projects I'd like to build an AJAX program on my own. Not too big. I'm new to the whole matter, however I have general knowledge in programming and a good understanding of the Web workflow. As for W3C standards, is it wrong sticking to them as if they were a platform? Is it a good idea to code havin...
I'm often asked at some point during the interview process to compare myself to my peers. For example, one of my first after-graduation jobs asked me to compare myself to my classmates. A job I recently interviewed for asked me to compare myself to my coworkers. I always play this down quite a bit. I'm always worrie...
OO programming literature is full of design patterns. Most books on object oriented programming dedicate a chapter or two to design patterns like factories and decorators. So what are the equivalent patterns in functional languages and why hasn't anyone written a book about them yet? Is there something special about fu...
I am about to release a piece of software that will be licensed with the GPLv3 (the project itself is "for fun" and has no commercial dimension in it). The software is intended to help designing digital clocks and I know the core functionality works as - beside having unit tests - I used it for designing a couple of cl...
So, I'm expending this email submission form script for a client and saw something rather strange to my experience. As you can see below, the original programmer has sanitised the user input. Is this a good practice or does this makes sense at all? // Build Message Body from Web Form Input foreach ($_POST as $Field=>$...
I come from a PHP background so I'm used to everything being in one place. I want to install a python program (Zine)so that I can hack on it. The instructions I've found install it to the system in multiple folders. I do not want to edit files that are installed in Linux system directories. What is the python way to la...
I have estimated the cost of a product by COCOMO, then I estimated it by FP too. the results were so different from each other! The cost estimated by FP was about two times more than the estimated cost by Cocomo. which one is more reliable as this product belongs to a large project. shoud I skip the FP result?
When I try to design an OO solution ,I generally use the CRC modelling wherein I list the class names (nouns), what they do(verbs) and how they collaborate with other classes. This blog has the below thing to say about this noun-verb approach ...This approach, which I will call “noun and verb,” is so limited I’l...

Is Entity Framework 4 with MySQL or Oracle mature enough to be used on production level web application? Can it provide high level of performance, or should we stick with just plain data access with SqlCommand?
I am trying to create a small CMS with ASP.NET MVC3, but I got confused in designing the administrator section. I decided to create two areas, one for users and another for admin. In my CMS I have a Post and a News object, and I want to put create/edit/delete functions in the admin area and other function that related...
I want something that I haven't so far been able to find in anything but theoretical papers and books. If it doesn't exist I'm rather dumbfounded because it sounds like a lot of people use these kinds of systems and that they work very well. Maybe what I need is some sort of combination of things, I'm not sure. Here...
Background I do game development as a hobby, and am looking for a better way to design them. Currently, I am using a standard OOP approach (I have been doing enterprise development for 8 years so it comes nartually). Take for example a "baddie" public class Baddie:AnimatedSprite //(or StaticSprite if needed, which inhe...
Normally when creating new global variables I do not define its access modifier. So as per java it will adopt property default access modifier. When I'm need to access that variable in out of default scope I change its access modifier else leave it as it is. So my question is "Am I doing it right way? Is it normal to h...
I need to use a long text as sample. Afterwards with an algorithm I will take a substring of it whose length is fixed (passed as parameter), but the startIndex is random, therefore each time it should take a different portion of that text. However I would take, if possible, a standard text as sample for my application....
I am just finishing my masters degree (in computing) and applying for jobs. I've noticed many companies specifically ask for an understanding of object orientation. Popular interview questions are about inheritance, polymorphism, accessors etc. Is OO really that crucial? I even had an interview for a programming job ...
This is a question of about design decisions. I find that there are so many different things I work on where reading a _kbhit() is amazingly useful but I can't find (read: there isn't) any functionality like that in the C++ standard. Example: Have a camera continuously running (and updating an on-screen window) until ...
What is the most appropriate definition of a Real time system? Is online railway reservation a real time system ? Is Aircraft control system a real time system? Is Process control system a real time system?
I currently use a Mac Pro for Xcode development, but am considering buying a MacBook Air when the newer models are released. How should I collaborate with myself when using both machines on the same project? Should I use Git, or should I just acess the Mac Pro as a networked drive from the MacBook, or something else?...
Gathering that map-reduce is being used to process huge amounts of data, I set out to understand it. My queries were: What class of problems does it aim to solve? How does it help breaking down of complex problems? Can I write a sample app, (locally!) to get started? After a lot of googling, blogs and wikipedia, I k...
I've been reading about hadoop and multi-node setups, and it says in the documentation that you must have a JVM and hadoop software already running on those nodes. My question is, do people install this software on each of these computers individually? or is there a software solution that automates this process? I've a...
What I have is business WinForms application written in C#. What I would like to do is to redesign it to meet multi-platform approach. I was thinking about architecture involving application server (executing all the logic and performing database operations) and thin client side running on Windows and Mac OS as well a...
I am very curious to hear input from others on a problem I've been contemplating for some time now. Essentially I would like to present a user with a text document and allow him/her to make selections of text and annotate it. Specific to the annotations i aim to achieve the following: Allow users to make a text selec...
Some people swear by closing their PHP files with ?>, some say it's more optimized to leave it off. I know that it's not essential to have it on there, I'm just wondering what the pros and cons are of doing this, and what best practice is.
I came across this term recently in a mail chain. Google tells me there is a term zero-day bug and that Microsoft and Adobe are the frontrunners :) Is there such a term as day one bug? What might that mean?
I have be developing in c# for the last about the last 8 years. I feel that i am quite experienced and knowledgeable in the whole .net platform. I have got to the point where i want to start learning objective-c. I have been watching dev videos, reading books and researching online. So far i am getting a good idea of...
Imagine a C++ framework as a business layer, but with controlling logic as well. E.g. user rights, state of the webflow etc. With some plain C code to access DB2. The whole framework is host based. We are looking for a way to replace the existing framework gradually with a java framework. The main challenges are: the a...
We have an app that is used for data mining on our client database. Typical uses include getting a list of clients and their email addresses, running reports about user transactions between certain dates and returning clients that live in a specific area. High level functional requirements are: Each data mining quer...
I've tried to read this series of books many times. I recently bought Vol. 4 to add to my shelf. I do actually hope to one day read and understand it. I only seem to be able to get the most surface understanding of any of it though. When I was in college I did one of those design your own courses. I decided for mys...
When I write code I always try to make my code as clean and readable as possible. Every now and then there comes a time when you need to cross the line and go from nice clean code to slightly uglier code to make it faster. When is it OK to cross that line?
I'm a programmer who's still in his teens. I've been doing some programming for a couple of years now, I started on Ruby, and later switched to Python due to the massive amount of learning resources there. I never really built anything worthwhile with Python, but feel like I learned a fair amount of programming funda...
I am developing a CAD - drawings to CNC machine code software. These CNC's have sort of a Instruction set which receive parameters,etc to do some blah blah job.

My employer is looking to purchase an enterprise account in the belief that it will enable us to develop and distribute apps for large clients of ours - however online it clearly states that the Enterprise account should only be used to distribute apps to the employees of the company that own the account. So my questio...
When I'm coming to home after the work, there left about 2-3 hours to work on my own projects. Some good programmers/developers also write books/articles/etc. I'm getting angry of to little time and interested how others can do so much - work in their main job, work on own projects and write articles/books? Do you kno...
While going through RFC1321, I came across the following paragraph: This step uses a 64-element table T[1 ... 64] constructed from the sine function. Let T[i] denote the i-th element of the table, which is equal to the integer part of 4294967296 times abs(sin(i)), where i is in radians. The elements of the...
My manager asked me to write a estimation of work hours and a risk estimation of source code changes for a defined task. While the first is no problem for me and there are many resources on the web, I cannot get my head around the latter one.
