I went to school for computer engineering. I have a little bit of self taught knowledge in computer programming, but very little in way of any real education in it. I've found myself in a computer science job for a friend and while its right now not too out of my abilities, I'm looking to extend my knowledge. I figured maybe trying to follow an open source project might be a good idea. Even if I don't contribute anything at first or even at all at this time, it may help in terms of learning good programming methods and skills. I'm most familiar with C# .NET in particular, but I have a bit of a background in visual basic and c++. I'm also more familiar with Windows in general and my experience with Linux is minimum at best (i can install and use ubuntu, but nothing too advanced).
So are there any good smaller open source projects that wouldn't take a great deal of commitment in terms of time (I can only provide a 5-10 hours a week to this) to just kinda get to know and learn how it works and what not? I'd be interested in anything that might touch on a little bit of SQL involved. My job involves DICOM but thats pretty specific so that'd really only be a plus if it were involved.
