Digitally Assisted Billiards Makes Everyone a Pool Shark


There's cheating, and then there's out-thinking the room. Georgia Tech's own Justin Needham and Matthew Straub are clearly headed for great things, as their Digitally Assisted Billiards is reason enough to give these guys a degree in our eyes. Using an array of low-end kit -- just an eBox 2300 embedded computer, Logitech webcam, 4- x 3-foot mirror, a VGA projector, pool table and a few extenders -- the two were able to concoct a system for visually displaying the expected trajectory of all possible shots based on the location of the balls still on the slate. For a much better idea of what we're hinting at, check the demonstration video after the break. [Via Hack-A-Day]

Swiss City Heats Public Pool with Computers



One of the byproducts of extreme computing power is heat. The problem is that all of this heat represents wasted energy, and instead of trying to recapture it, we use even more energy to dissipate that heat with air conditioning. But in the city of Uitikon, Switzerland, the local government, GIB Services, and IBM have come up with a rather unique solution.

The IBM-built data center run by GIB has been custom designed to directly transfer heat from the bunker full of refrigerator sized racks of computers and hard drives to a local public swimming pool. GIB is providing the heat for free, but the city did have to cover some of the initial equipment costs.

Its probably not the greenest solution to powering a massive data center, but it is certainly one of the more creative ways to reduce energy waste we've ever heard of.
