C# allows the use of #region/#endregion keywords to make areas of code collapsible in the editor. Whenever I do this though I do it to hide large chunks of code that could probably be refactored into other classes or methods. For example I have seen methods that contain 500 lines of code with 3 or 4 regions just to mak...
Is it advisable to create multiple classes within a .cs file or should each .cs file have an individual class? For example: public class Items { public class Animal { } public class Person { } public class Object { } } Dodging the fact for a minute that this is a poor example of g...
I've done some programming in a more-or-less functional style, but I've never really studied pure functional programming. What is the bare minimum needed to implement a functional language? As far as I can tell, you need: The ability to define a function The ability to call a function parameter substitution Some kind ...

I'm a 25 year old data consultant who is considering returning to school to get a second bachelors degree in computer science or engineering. My interest is data science and machine learning. I use programming as a means to an end, and use languages like Python, R, C, Java, and Hadoop to find meaning in large data sets...
The site I work on is almost entirely in Javascript, it just goes back (via Ajax) to the server for authentication, database access, things like that.

I've just released my application to the public, and I'm working on an updated version, but I really think I should keep track of ALL the code changes. In case some functionality suddenly starts failing, with a history of all the changes I made it would be a lot easier to figure out where I messed it up, in case the pr...
Does anyone out there have any experience porting a large Powerbuilder client/server application to a Java application (or another language)? By large I mean something on the order of 2 million lines of code and literally hundreds of database tables. How did you do it? How long did it take and how much did it cost? Wha...
In Java world, there are some scenarios where I see developers used to load the class rather than instantiation. What is the difference between instantiating and loading a class?
Esoteric languages are intriguing and can make you go 'Hmmm...', but what can we really learn from them? Is there a benefit to spending more than 5 minutes trying to write an application in an esoteric language? Have you tried one, and if so, what did you learn?
I mean did you ever reluctantly adopt a less than ideal solution because management told you that "customer is always right"? I'll go with mine first. A few years back, me and my team developed a website of quizzes. Users create quizzes, answer them, rate/tag/vote/share etc. If a quiz had more than 10 questions in it, ...
In my application, I have a listing of information that is deducted from a query that combines information from several entities. In itself, a very common situation. Now, the corresponding repository method should return a list that contains items of an appropriate type. Clearly, choosing an entity is not appropriate b...
After doing a bit of programming, I've become quite curious on language design itself. I'm still a novice (I've been doing it for about a year), so the majority of my code pertains to only two fields (GUI design in Python and basic algorithms in C/C++). I have become intrigued with how the actual languages themselves a...
I am looking for more information on a gradual release process - that is when you release new version of a software only to certain set of end users, mostly geographically limited (or limited by a reach of particular server). Google seems to be blind to this term - that indicates that's not how it's called. What's the ...
Do you use both Client-side and Server-side validation techniques side by side when validating input from a user, e.g. via a contact form? If so, is it really necessary? Are you over engineering?
I have a Maven project consists of around 100 modules. I have reason to decompose the project to so many modules, and I don't think I should merge them in order to speed up the build process. I have read a lot of projects by other people, e.g., the Maven project itself, and Apache Archiva, and Hudson project, they all ...
In an embedded device, during the initializing of memory locations, is there any convention that are being practiced. I mean, say setting every byte to zero or 0xFF or any other value.
I've often seen such comments be used: function foo() { ... } // foo while (...) { ... } // while if (...) { ... } // if and sometimes even as far as if (condition) { ... } // if (condition) I've never understood this practice and thus never applied it. If your code is so long that you need to know what...
Every time I've finished a project, there is always something that I've learned (otherwise I don't find it very motivating). But I can't remember everything, and much later I may stumble across the same problem that I encountered in a previous project but no longer how I solved it (or at least what attempts I made). So...
Project Managers/Technical Leads sometimes tend to be over enthusiastic when it comes to software. But during code reviews if instead of functionality of the code the only complain one hears is about formatting/spacing and similar trivial things, when there are far better things to discuss (Among other things I have no...

If I am localizing a piece of software that uses an external API, how should I handle error messages that originate in this API? I do not control the API, I only consume it.

So, before I came to my current place of employment, the windows OutputDebugString function was completely unheard of, everyone was adding debug messages to string lists and saving them to file or doing showmessage popups (not very useful for debugging drawing issues).

Developers, managers, or customers? I was recently involved in a situation where I felt like the customers were arbitrarily demanding for more developers on a team which already had too many developers. They were scared the project was going to be late (and it probably will be). Personally, I was scared we were going t...

Interested in peoples opinions of Cuda vs openCL following NVidia's Cuda4 release. I had originally gone with openCL since cross platform, open standards are a good thing(tm).

Idea I had this idea for a language feature that I think would be useful, does anyone know of a language that implements something like this? The idea is that besides inheritance a class can also use something called "imprinting" (for lack of better term). A class can imprint one or several (non-abstract) classes. When...
Certainly it is a productivity killer when a developer is constantly interrupted by other workers, bosses, etc - but it is even worse when the developer is constantly interrupted by his or her own tools and equipment. For example, if a developer must wait 10 minutes for each build he makes - so that he can iteratively ...
I have read most of the major threads on WPF vs. WinForms and I find myself stuck in the unfortunate ambivalence you can fall into when deciding between the tried and true previous tech (Winforms), and it's successor (WPF).

I'm just starting to learn C#. Coming from a background in Java, C++ and Objective-C, I find C#'s Pascal-casing its method-names rather unique, and a tad difficult to get used to at first.

And why is it often talked about? Like I know what OO programming is obviously... but people always say "Oh OO reuse is the biggest programming myth ever". What exactly does this mean?
Is there any existing in-use, or even just conceptual attempts at creating a markup or programmatic expressions for designing the layouts of websites other than HTML/CSS? If there are others out there and they do not appear to be in heavy use. Why is this?
I spotted a bug today in a web application that I develop and maintain for a client.

Swing is an integral part of the Java API. It is also the most popular GUI framework for Java. I still wonder, should every Java programmer still know, or at least be pretty familiar with, Swing (possibly excluding web developers)? There are alternatives (e.g. SWT), but they are not very widely used (compared to Swing)...
I've recently been in an argument with a colleague about technical questions in interviews. As a graduate, I went round lots of companies and noticed they used the same questions.

I'd like to get into web development using C++ as the "scripting language" on the server-side.

As long as the code in the base library is as loosely coupled as splitting it up into separate libraries, what's the problem? In general, having a lot of assemblies composing a .NET solution is painful. Plus, when code in one solution needs to be shared, it can just be added to the common library, rather than deciding ...
During my 5 years in IT as a software developer, I've noticed that developers have a strong distaste towards doing any documentation. The act of taking screenshots and creating documentation seems to be a painful and time consuming experience. In one company I worked for, we had a technical documentation team with two ...
I've found, what I personally believe to be a bad habit that a lot of developers seem to have adopted.
