Vani's 5 minute version of her longer YUI CSS talk is a little hard to follow because she was crazy enough to do most of it as a live demo, so lookup the slides and listen to the youtube thing at the same time!
Tim talked briefly about DBD::Gofer. Can you do 6000 "connections" to your MySQL server? To Oracle? With Gofer you can! I saw Tim over lunch today and he mentioned making the Gofer system able to use JSON for serialization which could make your database directly available to web-browsers or (more likely) just as a web service for Other Languages less blessed with lots and lots of database drivers.
