Psychologist Beating Math Nerds in Race to Netflix Prize 205

s1d writes "An almost-anonymous British psychologist named Gavin Potter has suddenly risen to the top of the Netflix prize charts. With his very first attempt, he got a score which took the BellKor team seven months to reach. Currently at a score of 8.07, he has only five teams ahead of him now in the race for the ultimate Netflix algorithm. 'Potter says his anonymity is mostly accidental. He started that way and didn't come out into the open until after Wired found him. "I guess I didn't think it was worth putting up a link until I had got somewhere," he says, adding that he'd been seriously posting under the name of his venture capital and consulting firm, Mathematical Capital, for two months before launching "Just a guy." When he started competing, he posted to his blog: "Decided to take the Netflix Prize seriously. Looks kind of fun. Not sure where I will get to as I am not an academic or a mathematician. However, being an unemployed psychologist I do have a bit of time."'"

Probe Captures Avalanche on Mars 69

mdekato writes "MSNBC reports that NASA's Mars Reconnaissance Orbiter has captured an avalanche on Mars' surface as it happened. Very good still images show what must have been an awesome sight. 'The full image reveals features as small as a desk in a strip of terrain 3.7 miles (6 kilometers) wide and more than 10 times that long, at 84 degrees north latitude. Reddish layers known to be rich in water ice make up the face of a steep slope more than 2,300 feet (700 meters) tall, running the length of the image. Mars' north pole is covered by a cap of ice, and it even snows there. The scientists suspect that more ice than dust probably makes up the material that fell from the upper portion of the scarp.'"

Lessons From the HD Format War 308

mlimber writes "The New York Times' Freakonomics blog asks a panel of experts, 'Is the battle between HD-DVD and Blu-ray really over? What can we learn from it?' The panel suggests, among other things, that Sony achieved a Pyrrhic victory because high-def DVDs will be outmoded before they reap enough profits to make up for what they (and Toshiba) paid out for both product development and bribes to win the support of content providers."
