In today's sessions that I attended I liked the following:
JRuby: Why, What, How... Do It Now
This talk is a good introduction to (J)Ruby the language and important applications of (J)Ruby. And many pointers to related (J)Ruby sessions. Nice summary!
JavaScript programming language: The Language Everybody Loves to Hate
great talk by Roberto Chinnici. Nice summary of functional and prototype-based object orientation aspects of JavaScript. You can easily impress your friends will some neat snippets of JavaScript
You may want to continue the fun by reading Doug Crockford's pages, if you have not do already!
At 7.30 PM, we (I and Kannan) talked about BTrace. There were many interesting questions/discussions -- both during and after the BOF! Today (Wed May 7) will be a Blu-ray day -- it starts with TS-5449 Java Technology for Blu-ray and TV: Creating your own Blu-ray Java Discs session. It is about the open source project @ http://hdcookbook.dev.java.net. Meet you all there!
