I am quite puzzled why you cannot find a Java project to work in, to be honest. Most open source projects are screaming for programmers, when you are willing to code for free, and your aim is to learn about teams, contributing to one of those projects is one way to get experience.
Yah I think I'm just to picky, I browsed sourceforge for java projects a few times and they were all really boring projects or things that where above my head, I don't have much experience in non-game programming and I'd prefer to work on a real-time graphics application. I suppose it would do me good to join a regular project and learn more about 'regular' programming though.
Any suggestions for open-source projects, or websites other than sourceforge I could try?
on a side note I feel like someone could write some simple code that could crack these new captchas, you can always find a perfect right angle of white space where the block needs to go cause they are squares, then you could just calculate which right angle each block fits in better by simulating placing it in both and checking if it continues the colors along the lines of the right angle. I did a terrible job explaining that, it's ok though I'm sure it wouldnt work anyway, I just woke up.
