If you just want to practice programming, a Blog is a great idea, as invertedlambda suggested! You can also try cloning sites you like, such as Twitter, Facebook, Hacker News. Or maybe a text-mode game. Anything that you might think is cool. Or a tool for reading from some API you like. What about a command-line tool for getting the weather report based on your IP?
