Keeping Fresh

Hello /prog/. Don't normally come on these boards, but I have a relatively simple question that I think you could help me with.

I've finished my first semester of Comp Science, and learned a fair bit of Python programming in the process (not the best programming language, I know).

Basically, now that the class is over and I'm not being exposed to the Python language on a regular basis, I was wondering what /prog/ does to keep up to date on their programming knowledge? If anyone could suggest some projects to start on, or a database of sample problems to just do in spare time, I'd really appreciate it. Otherwise, just discuss what you do on a daily basis to maintain your knowledge.

I appreciate it.

That may be a good idea. I'm going to be getting into C next semester, and I may pick up Java just as a side project.
