You can catch some videos of the conference over at Viddler
The conference had a great turnout. Fellow ruby nerds came from Texas, and as far as Chicago! A welcome change of pace, since Acts_as_conference stopped 2 years ago.
Two of my favorite talks were:
Given by Avdi, Avdi Devblog and going over all the subtle nuances about exception bubbling, re-raising, exit codes, and threads.
Given by Pete, PeteOnRails Blog he shows several tools available for ruby to deal with geographic data, and map projections.
