The last keynote of Tuesday evening at OSCon 2008 was entitled "Temporally Quaquaversal Virtual Nanomachine Programming In Multiple Topologically Connected Quantum-Relativistic Parallel Timespaces...Made Easy!"
Damian Conway is a speaker that should not be missed. He spends his time hacking perl to do fascinating and obscure feats of technology such as time travel. This video is just over an hour of rolling laughter that will entertain you into realizing what a genius Damian Conway is.
Now, most of my exposure is within the MySQL Community, so if folks could pass the links to the video along to other communities, that would be great.
