I made a little utility to download all Imgur images and albums that a user has submitted to Reddit. I worked on it to learn Python and regex. My conclusion was that Python is fun and regex is fiddly but interesting.
You can download it on GitHub. It’s called rid.py (short for Reddit-Imgur Downloader).
Also, my friends and I are working on a chess game, the code for which can be seen on GitHub. It is going to be used to practice the basic design methodologies that we’re going to use for a group project, like careful documentation. We’re looking to expand this into a much more ambitious game.
