I can't believe it's been a year since I was at JavaOne last year - it seems like only yesterday I was getting my picture at Duke's 10 year birthday! (only kidding, of course :-))
Although I'm not in San Francisco for this year's conference, Microsoft do have a couple of sessions and a booth on the trade floor. I've been following Mohammed's excellent blog on the in's and out's of the event. If you in the Moscone Center, be sure to track down the team!
