Submission + - Electricity revives "bleached" coral (nationalgeographic.com)

psyopper writes: "Just a few years ago, the lush coral reefs off Indonesia's Bali island were dying out, bleached by rising temperatures, blasted by dynamite fishing, and poisoned by cyanide. Now they are coming back, thanks to an unlikely remedy: electricity.

From the article:

"[sic] The project — dubbed "Bio-Rock" — is the brainchild of scientist Thomas Goreau and the late architect Wolf Hilbertz... Goreau's Bali project constructs metal frames, often in the shape of domes or greenhouses, and submerges them in the bay. When hooked up to a low-voltage energy source on the shore, limestone — a building block of reefs — naturally gathers on the metal. Workers then salvage coral that has broken from damaged reefs and affix the pieces of live coral to the structure. Goreau and his supporters say the electricity spurs the weakened coral to restore itself.

Indeed the corals on the structures appear vibrant, and supporters say they have rebounded with impressive vigor. The coral in Pemuteran teems with clownfish, damselfish, and other colorful tropical animals."

"Rod Salm, coral reef specialist with the Nature Conservancy, said while the method may be useful in bringing small areas of damaged coral back to life, it has very limited application in vast areas that need protection. 'The extent of bleaching ... is just too big,' Salm said. 'The scale is enormous and the cost is prohibitive.' ""

Submission + - ATI/AMD to Release Open Source Linux Drivers (wordpress.com)

psyopper writes: "According to Michael Larabel at Phoronix, AMD/ATI have announced that their latest fglrx driver, 8.41 is here, it works, it renders, it competes and is going open source. Directly from the announcement page:

"Rumors and speculations have been flying around for months about ATI/AMD opening up the source-code to their Linux display driver or providing their GPU specifications to community developers. This for the most part had started after Henri Richard's statement at the Red Hat Summit earlier this year. Well, those rumors can finally be put to rest. AMD will be providing NDA specifications, an open-source library, and there is a new open-source graphics driver as a result. AMD will continue producing a closed-source proprietary driver; however, they are opening the source-code to a critical library with accompanying GPU specifications for X.Org developers. To get the ball rolling, AMD is also funding the development of a new open-source R500/600 driver."

How well does it stack up, performance wise? The R600/HD2600 is dead on to Nvidia's 8600."
