JavaOne doesn't start until tomorrow, but today we saw a ton of people here at the Moscone Center in San Francisco. Sun held their annual CommunityOne open developers conference, and Sentilla was there. What attendees didn't expect was that Sentilla's pervasive computers are watching their every move. Keep an eye out for Sentilla as you walk through the Moscone Center.

I spent time today talking to John Gage, Sun's Chief Researcher, about pervasive computing. As many of you know, John opens every keynote session with facts and observations about Java and the conference. Last year he issued a call to monitor and react to our environment by gathering, analyzing, and acting on real data from "small devices". "Because we have these small devices, we have the tools in place ... that all of us realize is our fundamental duty to take these devices and apply them to human end. To make visible what is invisible, our impact on the planet," Gage said.

John is opening Tuesday's keynote session with Rich Green (where Neil Young will be making an appearance). Be sure to attend, John just might let you know how Sentilla has answered John's call to better understand the world around us.

Not going to JavaOne? No problem! JavaOne sessions are broadcast online.
