Site News

I'm again amazed at the level of quality of the articles posted on CodeProject, and that thing that I love the most is the breadth of the topics covered. However, we still get lots of "Do you accept articles on technology X" and we always answer "Absolutely!". We have hundreds of articles on Rails, PHP, Objective-C, a squillion on Java, tens of thousands on .NET and then onto Haskell, Erlang, F#, Fortran, Cobol and of course BASIC. How can you not love an article about BASIC.

Someone, somewhere, wants to read your article, so if you have an itch to write up your code, your idea, or even just your painful lesson, please do.

The top articles of last month are:
