Boiled Frog from a Nation of Suspects writes "The Oyster card, an RFID single-swipe card (which was recently cracked), was introduced to London's public transport users purportedly to make their lives easier. Now, British Intelligence services want some of the benefits by trawling through the travel data amassed by the card to spy on the 17 million Britons who use it. The article notes, "Currently the security services can demand the Oyster records of specific individuals under investigation to establish where they have been, but cannot trawl the whole database. But supporters of calls for more sharing of data argue that apparently trivial snippets — like the journeys an individual makes around the capital — could become important pieces of the jigsaw when fitted into a pattern of other publicly held information on an individual's movements, habits, education and other personal details. That could lead, they argue, to the unmasking of otherwise undetected suspects."

Jonathan writes "Today, the 14th of March, is Pi Day 2008. Pi Day is internationally celebrated in honor of the mathematical constant "Pi," who's actual value will — now and forever — remain unknown. NeoSmart Technologies has a run-down on the history of Pi, Pi Day, and the significance of Pi and other such "magical numbers" to science and technology. 'Pi isn't just a number that you can use to calculate circle-related mathematics, it's a symbol of something by far greater. Pi is one of many "magic" numbers that are found everywhere — if you know where to look. These magic numbers can't be explained, they just are. And if you use them right, they make it a lot easier to do a lot of really complicated things... In a way, they're a testimony to technology and computers (or vice-versa, depending on how you look at it).'"

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."'"

An anonymous reader noted a fun follow up to the Star Trek Home Theater we disussed not that long ago. "A retired naturalist thought that her cellar would be a great Batcave, and transformed it into the ultimate home theater. That's right, a Batcave themed home theater created by New Hampshire-based installer DC Audio Video Systems. The set-up includes prop bats which hang from above, a motorized 110 16:9 Stewart Electriscreen, Triad Silver THX Speakers, and a Sony G90, a $36,000 commercial 1080p 2500 x 2000 CRT projector. The room also features eight black, motorized leather recliners and a LiteTouch LC5000 System for Lighting Control." Update 18:16 GMT by SM: updated link to the original story.

James Hardine writes "Wikileaks is reporting that the CIA has funded covert research on torture techniques, and that the NSA has pushed tens or hundreds of millions into academia through research grants using one particular grant code. Some researchers try to conceal the source of funding, yet commonality in the NSA grant code prefix makes all these attempts transparent. The primary NSA grant-code prefix is 'MDA904'. Googling for this grant code yields 39,000 references although some refer to non-academic contracts (scolar.google.com 2,300). The grants issue from light NSA cover, the "Maryland Procurement Office" or other fronts. From this one can see the broad sweep of academic research interests being driven by the NSA."

A user writes "Medical researchers in Britain have succeeded in growing a heart valve from adult stem cells taken from bone marrow. The research is being reported in the journal of the Royal Society today. Growing a heart value from your own cells means that tissue rejection isn't an issue."

Ant writes "Dark Horizons reports after much talk and posturing over the future of "The Terminator" franchise/series in recent years, something surprising has happened: The Halcyon Company has acquired the franchise rights to the popular movie series and intends to make a new trilogy that would anchor their movie company..."
