This website contains multiple puzzles and challenges for coders in several languages. I haven't found anything too difficult, but the puzzles are enough to get your mind going a bit. Whenever I'm not sure what to be scripting, I head on to this website to warm up on some languages I have not touched in a while or to practice one I just learned. Anybody else find a site similar to one like this?
