"The [textbook] industry charges outrageous prices for new textbooks while simultaneously doing everything it can to make older versions unusable or obsolete. There is simply no reason that a new calulus textbook should cost $157. The study of calculus, at least the type of calculus that most of us need to study in high school or undergraduate programs, has not changed significantly in decades." - Textbook Revolution.

DTV beta for Mac is now live. DTV is a new, free and open-source platform for internet television and video. The goal here is to make sure that internet TV is open and independent. Free, open source software and open standards mean anyone can watch and everyone has a voice.

CommonTunes.org, a community directory of freely distributable music. With tags. Also see CommonFlix & CommonBits. Oddly enough, the site itself is "All Rights Reserved". Pity about the color scheme.
