Jaunty UDS has finished. I haven't been there but planet.ubuntu.com provided a good coverage. Jono Bacon posted on his blog a link to videos from the Jaunty UDS. You might find schedule to be helpful while downloading/watching them. I couldn't find the most interesting sessions though =( the Upcoming Lauchpad Features, Brainstorm Overview, Becoming MOTU, Python 3000 QA, ext4 and so on. Basically anything that happened in Olympus Mons hall. That's disappointing because there also was a session on Google Apps Engine. Maybe we will find it on Google Code YouTube channel or something like that.
