A warehouse of information gleaned from SourceForge for use in empirical software engineering research. There's going to be a full-day workshop at SIGCSE'08 (Portland, March 2008) on building a similar repository for use in CS education research---perhaps the two efforts could be combined?
Nicolaas Handojo and Jeff Okawa built the first version as a CSC49X project a couple of years ago; John Green & co. have rebuilt it, and are looking for beta users. Its purpose is to manage localization for open source projects: groups can post text that needs translation, and volunteers can oblige them. Give it a whirl...
Along with Brandon King, Chris Lasher, and Rick Wagner, Titus has been one of the major contributors to Software Carpentry since it went on the web. He taught a more advanced course along the same lines last year, and has been generous enough to put his notes up for public use. I need to fold a lot of this stuff (particularly the material on packages) into the main notes.
Its creators are up-front about the fact that they're only measuring visibility of web publications (both formal and informal). Since that's what under-30s care about most, though, it's an important metric. Toronto is the top Canadian school, in the #28 spot; the only non-US school ahead of it is Cambridge. (And if you object to their results, feel free to create and apply a different method and publish your findings as well.)
Someone in Saskatoon just updated the Wikipedia entry on "Hogwarts Houses". Someone in Edinburgh then updated the entry on "Mr. Blobby", and someone near San Diego revised the entry on Elie Wiesel. The next two changes were from Malaysia, central Spain, and the middle of Finland (where someone edited the entry on "Niger"). I wonder if there's any way to set this as my screensaver?
