I'm trying to convert a Fortan77 program to C#. I have a subroutine with about 650 lines of code and horrific GOTO statements all over the place. I'm having a lot of trouble even starting to visualise the flow of the subroutine to figure out what it does. Is there anybody with experience in this sort of thing who could...
I have some computer science students in a compulsory introductory programming course who see a programming language as a set of magic spells, which must be cast in order to achieve some effect (instead of seeing it as a flexible medium for expressing their idea of solution). They tend to copy-paste code from previous,...
What are the consequences of allowing multiple inheritance in a programming language? What characteristics of multiple inheritance create an environment such that the use of multiple inheritance tends to result in source code that violates one or more principles of Object Oriented Programming and quality software engin...
Recently I've been working on refactoring parts of the code base I'm currently dealing with - not only to understand it better myself, but also to make it easier for others who are working on the code. I tend to lean on the side of thinking that self-documenting code is nice. I just think it's cleaner and if the code s...
This is a minor niggle, but every time I have to code something like this, the repetition bothers me, but I'm not sure that any of the solutions aren't worse. if(FileExists(file)) { contents = OpenFile(file); // <-- prevents inclusion in if if(SomeTest(contents)) { DoSomething(contents); } e...
I have been happily using JQuery for the last 2 years and have been quite sucessful creating some really cool functionality with it...so I am very comfortable with it.

I think we've all been there: You hear of someone say "hey, wouldn't it be nice if platform X had feature Y?" You look around (on SO!), the feature really doesn't exist, even though it probably would be useful in many contexts. So it's pretty generic. Your mind wanders for a bit. "How tough would it be? Well, it'd prob...
If asked a series of technical questions in a programming interview, does it look bad to admit when you don't know the answer to a question? In other words, does admission make you look incompetent or ill prepared? Or, is it assumed that no one will know the answer to every question? Does admitting it instead of tak...
I'm working on a small educational project on MVC 3, and I'm facing a small problem, when attempting to handle validation in my application through a wizard.

What are the relative merits (or demerits) for implementing an Erlang-style "Continuation" pattern in C#. I'm working on a project that has a large number of Lowest priority threads and I'm wondering if my approach may be all wrong. It would seem there is a reasonable upper limit to the number of long-running threads ...
As a C & Objective-C programmer, I'm a bit paranoid with the compiler warning flags. I usually try to find a complete list of warning flags for the compiler I use, and turn most of them on, unless I have a really good reason not to turn it on. I personally think this may actually improve coding skills, as well as poten...
I keep hearing about the desperate recruiting efforts of companies in tech hubs such as SF and NYC. However, every time I'm contacted by a startup I'm told the position is on-site and working remotely isn't possible. Let me clarify that these are tech startups. They should be very comfortable with the idea of using tec...
I'm currently new to freelancing as a programmer and need to work out what some of the "norms" are without making myself look like an amateur.

I come from php community and just started learning Python. I have to create server-side scripts that manipulate databases, files, and send emails. Some of it I found hard to do in python, comparing to php, like sending emails and querying databases. Where in php you have functions like mysql_query(), or email(), in p...
I am a lone developer and maintain a SVN server for source control. So far, I haven't followed anything specific while committing my changes. I was just reviewing my previous commits, and couldn't make any sense of my comments. What do you put in comments while committing your checkins?
The best thing I like about ASP.NET MVC, is that you can directly call a server method (called action), from the client. This is so convenient, and so straightforward, that I really like to implement such a model in ASP.NET WebForms too. However, in ASP.NET WebForms, to call a server method from the client, you should ...
I currently work with Zend Framework, but I also know about CodeIgniter and Kohana. I've just wonder that should I stick to a framework or depend on my purposes? Because I think I cannot master everything.

I'm learning CSS "seriously" for the first time, but I've found that the way you deal with multiple CSS classes in CSS and HTML quite inconsistent. For example, I learned that if I want to declare multiple CSS classes with a common style applied to them, I write: .style1, .style2, .style3 { color: red; } Then, if ...
I am a C# software developer. I was recently approached by a client to develop a multiplayer board game (max 4 players). I fiddled around with WCF, WPF and EF 4.1 to get something going but I keep running into small stumbling blocks. It certainly does appear that integrating all these technologies into one solution ...
I'm trying to refactor my application into MVC, but I'm stuck on the M part. In a database-backed app, the model is implemented in the app code, right? But then, what is in the database -- is that not also the model? (I'm not using the database as a simple object store -- the data in the DB is an enterprise asset).
When documenting software I traditionally write a plain text file (like a README.txt) which works well, but unfortunately cannot contain images like HTML can. Unfortunately images must be stored as separate files with a normal HTML document (using <a href=".../foo.png">) which give unnecessary clutter. The "Save a sin...
there are a couple of discussion on SO about setter methods returning "this" type. And looks like java 7 had the proposal of void methods returning this. But this proposal could not make it to java 7 features. I could not find if this proposal is moved on to java 8 or future or have been completely discarded. Is it? R...
Velocity Template Language's set directive requires a variable on the left hand side. This doesn't work. #set ( $entries.add("d") ) Even though I have no use for the return value of add("d"), I have to assign it to a variable. #set ( $x = $entries.add("d") ) I want to communicate that the variable is necessary, but...
All. I am creating some libraries for other teams in my company. They all have different logging mechanisms. I want to provide trace information of what my libraries are doing. What should I to achieve this? Thanks
I'm probably over-thinking this and it might not matter in the scope of things, but I'm wondering how people build up initial versions of their projects in source control? I'm talking about when you start with nothing but an idea, so no forking an existing project or anything. When do you do your commits before having...
I have an interface called Cell. In the start of the code, I read input data from which I can come to know the implementing class (not as a class object but I can know for example the string). And after that I need to call the constructor for the implementing class to initialize an object. What would be the best way to...
So my professor was giving back some feedback on a project I've been working on. He docked a few marks for this code: if (comboVendor.SelectedIndex == 0) { createVendor cv = new createVendor(); cv.ShowDialog(); loadVendors(); } This is in a combobox "index changed" handler. It's used when the user wants to creat...
I am part of a software deveopment team. Originally there were just 2 of us, and two applications. To ease our job we create a set of libraries, handling stuff like GUI, database access, calculation, business rules etc, so that we can reuse them in our applications without implementing them twice. Now the team grew, 6...
I have an ASP.NET C# application that needs to go off and iterate through a directory of .xml files and do some processing on the data inside them.

I have a set of steps that need to run sequentially over a list of data. However each step only operates on a single piece of data at a time. Because of this, I can run the steps asynchronously. For example I have two pieces of data, and two steps. When step one is done processing the first piece of data, it passes it...
TL;DR: I need to develop an app which should look kind of the same on desktop and as a website incarnation. Since I am a web dev and have never developed for desktop, I want to use a language that can embed a webkit view so I can use the same HTML/JS front-end for both usages, and minimize the learning curve for GUI at...
Please feel free to suggest a better name or way of explaining this question - I wasn't quite sure what to call it.

Did you try the tests yourself, and if so do you feel the ...
Microsoft technologies keep getting better but they do so on the expense of adding one more abstraction layer every time. In the early stages we used to play with C# code and SQL procedures to perform CRUD operations. Then generics came along with ADO.NET, DataSets, Entities. Next, LINQ came offering LINQ to SQL, to XM...

However, I can't find any examples of or guidance on how to read/write to a memory mapped file that, underneath, is bound to a text file. Can anyone shed some ...
I'm frustrated by the lack of concrete explanations on how to go from being able to script (bash, awk) and write simple applications (c, php, python) to designing and developing larger, more complicated software.

Among the reasons for a developer to publish a self-written library as open source library, there is definitely fame. Now when it comes to Boost Libraries, they are available and promoted in a very anonymous and impersonalized form. The name of the author will be readable in the documentation and source files, but be ...
Our library extends another (third-party) library. When we create a child class in our library, and want to throw exceptions, should those exceptions extend the exceptions from the parent class or from our own namespace? For example: class Their_Exception extends Exception {} class Their_Class {} class Their_Class_Exc...
Recently starting my first job as a software developer, I was a little thrown to be told that I did not have to follow any naming conventions in my code.

As I've written about in other questions here, the project that I'm working on now has no software process. That means no documentation (including hard copy requirements or specification), no source control, no bug database, bugs are "fixed" (hopefully) and new code is added at the same time, and no formal testers - we...
Since this question seems to be pretty subjective, I'm posting it here. Let's say you're writing your own version of Stackoverflow using ASP.NET MVC, so there are classes like Question, Answer, User, etc. Since you're lazy, you decided to use entity framework. So, all the classes mentioned above have navigation propert...
I'm looking for an approach to the following problem: I have a reusable library. It contains a controller class, in the MVC sense.

I heard about Domain Driven Development from a developer in the area. He talked it up like it was just about the silver bullet to changing requirements. I read the wiki. Still not too clear. What is "3D" in practical terms? Is it really that amazing that now UML class diagramming is just obsolete?
Nearly a year ago, I started writing a game. I was just messing around at the time, but now I'm pretty serious about it. As it's grown, it's taken on the responsibilities of a major game engine, as well as the game logic of an actual game. At some point, I decided I should break the two out, and designate a game and a ...
There is an utility we have which is used to upload files (and perform other operations on the file) to a network shared location. The file size tends to vary from a few mb to 500 mb. A suggestion has come up that we should maybe support multi-threading when uploading the files to the shared location - not required to ...

When I was originally learning about SQL I was always told, only use triggers if you really need to and opt to use stored procedures instead if possible.

I am not under any time constraint. About ...
I have been coding on and off on C and to a certain extent on C++ since my college days(2003), but I never had the opportunity to work with a hard core programming responsibility, which could have taught me "industrial grade coding" better and what is needed really for solving real life problems. To me it looks like I ...

I recently learned of a program called Total Commander. It's a Windows Explorer replacement and has its own stuff to copy files.

We have a small webdesign firm, and count with one designer. We can currently not afford too much expansion in the design area, so that means that the designer creates the main design of a website (which often means: the homepage), and the programmers then work with this to make it into a website. In general, this work...
I'm wondering what are the specific differences in the terminology we use for grouping related parts of code. I've sometimes seen the terms used interchangeably: many OO languages even use the keyword "function" to define a method. (Why?) If you wanted to be precise, what are the specific meanings of each? Or is it jus...
So, I'm a computer science major and I'm also a huge fan of the no-longer-on-TV show, Numb3rs.

It's not uncommon to hear of decoupling the UI from program logic, or database design/access from program logic...or even program logic from itself. However, I've never heard of an approach to generalizing or abstracting away the details of threading tasks to the logic (aside from Tymeac, an Android-specific package). ...

I have a form with several controls on it. Every control has to be declared in the class, formatted in the constructor (-size, location, event subscription etc), and its event-handlers declared, again, in the class.

For someone who doesn't have much real world experience yet, the notion of maintainable code is a bit vague, even though it follows from typical good practice rules. Intuitively I can tell that code can be well written, but not maintainable if for example it hard-wires information that is subject to constant change, bu...
Yes, you can access the mobile web site from a range different mobile devices, but the platform, I suppose, is still the web server and the client browser (the latter ideally being the "same" on any device).

There's a quotation by Ralph William Gosper, Jr that says: A data structure is just a stupid programming language. What did he mean by this? Alas, all I can find in Google about it is relentless copy/pastes of the quotation itself, without any context.
