Sentilla Blog

Are you interested in learning the ins and outs of Sentilla's novel Java platform? Do you want to kick the tires and learn how to build efficient pervasive Java applications? Do you have questions about how garbage collection works? Do you want to know about the Driver model? How about performing asynchronous operations from a synchronous threaded context in Java? And how do you manage all those threads on a resource constrained device with only 10kB of memory?

Day Three at JavaOne brought more application ideas, and a video interview with Joe.

Here were the three coolest apps of the day:

As mentioned by John Gage and James Gosling in the keynote on Tuesday, Sentilla has been monitoring the behavior of people in the Moscone Center. We know when they enter and leave each room and we know the environmental conditions in each room. Together, we have great data that is giving us a good sense of the resources we're using. For example, we can see each time the H/VAC system turns on, we can see an increase in temperature when people (where each person is the equivalent of a 100W light bulb) enter a room, and we can see when the Moscone Center forgets to turn off the lights at night. These are just a few of the interesting bits of information.

To explain this to the audience, Gosling held up a Sentilla pervasive computer in the opening remarks on Tuesday to illustrate how we're injecting intelligence into the real world. Gosling and Gage also showed data that we collected on Monday.

What do 15,000 Java developers have in common? Besides a love of object-oriented programming languages and an oddly-shaped mascot named Duke, Java developers act en masse. How do we know? Sentilla was commissioned by Sun Microsystems to instrument the Moscone Center in San Francisco with over 200 pervasive computers during the 2008 JavaOne conference. Sun wanted to have greater insight into the behavior of attendees during the conference so that organizers could adjust energy-usage in real-time and better plan for future events. Each morning, John Gage presented Sentilla's findings.

The first day of JavaOne is over, and what a day it was!

The tone was set fairly immediately, when the opening Session of the entire conference highlighted Sentilla right out the gate. That's right: among the more than 200 exhibitors in the conference -- including major heavyweights like Oracle, Intel, Motorola -- Sentilla was the first company mentioned by Sun. That was really exciting. See for yourself from Sun's webcast replay (we're mentioned starting at 3:52.)
