The sessions I attended today were rather amazing.

Annotation Hammer w/ Venkat Subramaniam

The first session I attended was venkat talking about using annotations in java. I've used annotations all over the place, but I never really knew how to use then internally or why you would want to use them. It really cleared up a lot of the clouds floating around annotations. I found this session quite helpful.

Yahoo UI! Library w/ Scott Davis

The next session I attended was Scott Davis talking about the Yahoo UI libraries.

Google Web Toolkit parts 1 and 2 w/ David Gaery

BOF Discussion w/ Scott David and Venkat Subramaniam

more to come..
