Google I/O 2010, Google's developer conference, is this week in San Francisco, California. If you couldn't get in to this sold-out event, you can still watch the keynote presentations live at the GoogleDeveloper YouTube channel

. The first presentation is at 9 am Pacific Time on Wednesday, and the second is at 8:30 am Pacific Time on Thursday.

All sessions will be live-blogged using Google Wave, and if you have a Wave account, you can watch them unfold even if you're not attending. I'm the official Wave note taker for the App Engine sessions on Wednesday; another AE team member will do the Thursday sessions. You can add yourself to each session wave today: just visit the session page, click "View Wave" to open the wave, then click the Follow button. Each session also has a Buzz/Twitter hashtag for more backchannel goodness.

Attendees, don't forget about App Engine office hours, running all day both days in Space G. AE team members will be staffing this booth along with chairs and a whiteboard to talk with you about your App Engine app. I'm told there will be a limited number of copies of PGAE floating around. (One per person, please. :) )
