Mentioned in some comment thread, but I just fixed LuckyTubes (http://www-personal.umich.edu/~swolchok/luckytubes/), my YouTube search/download/rip tool using youtube-dl and ffmpeg, to correctly rip the audio stream from the downloaded video without transcoding to 64 kbps MP3 (oops). It's called LuckyTubes because it does a "feeling lucky" YT search for the terms you type in. Code is at http://github.com/swolchok/luckytubes/ .

No code for this project, but UmBus (http://mbusreloaded.com/umbus) is my pet project to let UMich students get the GPS-estimated arrival times for the uni buses via text messaging. If I weren't so late to the party, I would try to compete with www.nextbus.com .
