Submission + - Green Your Server Farm (

An anonymous reader writes: Jer Faludi at Worldchanging has put together a terrific overview of the recent advances in creating greener tech for server farms, which — since they make up about 1.5 percent of planetary energy consumption — are a major target for sustainable computing efforts.

It's not just the computers themselves that use all this power: the combined heat output of all these servers, hard drives and network gear is so large that massive air conditioning is required to keep it all from overheating. "Cooling is about 60 percent of the power costs in a data center because of inefficiency," said Hewlett Packard executive Paul Perez in Data Center News. "The way data centers are cooled today is like cutting butter with a chain saw." Cooling capacity is often the limiting factor of how big these systems can be — I've talked with more than one engineer whose data center facility sat half empty or more; even though there was plenty of room for more servers, the building's air conditioning was maxed out.

Submission + - Seagate's 1TB Barracuda 7200.11 Drive Tested (

MojoKid writes: "Seagate was surprisingly late to join the small, but elite club of storage manufacturers shipping one terabyte (1TB) class hard drives. First out of the gate was Hitachi, who made it to market several months beforehand with a high-density five-platter 1TB hard disk design. While Hitachi's performance, thermals, and acoustics have all been tested to be fairly solid, many high-end buyers have been waiting for other manufacturers, namely Western Digital and Seagate, to get into the mix as well. This review shows that, the Seagate Barracuda 7200.11 is one of the most advanced consumer level hard disks on the market. The drive showcases second generation perpendicular recording, 32 MB of cache, excellent multi-tasking performance, very light power consumption and relatively quiet acoustics, not to mention its massive 1 Terabyte capacity."

Monitor Draws Zero Power In Standby 405

fifthace writes "A new range of Fujitsu Siemens monitors don't draw power during standby. The technology uses capacitors and relays to avoid drawing power when no video signal is present. With political parties all over Europe calling for a ban on standby, this small development could end up as one of the most significant advances in recent times. The British Government estimates eight percent of all domestic electricity is consumed by devices in standby."

Feed Engadget: Brown University demonstrates Drawing on Air system (

Filed under: Misc. Gadgets

It's been a tick since we've heard any news on the 3D drawing front, but a number of computer scientists from Brown University are putting the art back in the proverbial foreground with its Drawing on Air installation. Put simply, users can slip on a virtual reality mask, grab a stylus and tracking device, and go to town. The system uses "drawing guidelines, force feedback, and two-handed interaction" to assist artists in drawing more precisely, and once movements are made, the patterns are transferred to a computer for use in 3D modeling and design programs. Unfortunately, such a system can't currently be priced at points which John and / or Jane Doe would be happy with, but the researchers did state that commercialization wasn't "too far away" and that prices should decrease from "thousands of dollars to hundreds of dollars in the next few years."
