Among the other stats: for every dollar spent on computing equipment in data centers, an additional half dollar is spent each year to power and cool them; and half the electricity used goes for cooling. Iceland, with its cool climate and abundant cheap power, is courting big users like Google and Microsoft as a future data center location. (Can't help thinking they're gonna need a bigger cable first, though.)"

Lawrence Person writes "According to a story up on Writer's Weekly, Print on Demand publishers are being told to use Amazon's own BookSurge POD printer or else Amazon will disable the 'buy' button for their books. After hemming and hawing, an Amazon/BookSurge rep 'finally admitted that books not converted to BookSurge would have the "buy" button turned off on Amazon.com, just as we'd heard from several other POD publishers who had similar conversations with Amazon/BookSurge representatives... their eventual desire is to have no books from other POD publishers available on Amazon.com.' So much for Amazon's Vision Statement: 'Our vision is to be earth's most customer centric company; to build a place where people can come to find and discover anything they might want to buy online.'"

Ace905 writes "For years the razor-sharp beak that squid use to eat their prey has posed a puzzle to scientists. Squid are soft and fragile, but have a beak as dense as rock and sharp enough to break through hard shells. Scientists have long wondered why the beak doesn't injure the squid itself as is uses it. New research has just been published in the the journal Science that explains the phenomenon. One of the researchers described the squid beak as 'like placing an X-Acto blade in a block of fairly firm Jell-O and then trying to use it to chop celery.' Careful examination shows that the beak is formed in a gradient of density, becoming harder towards the tip end. Understanding how to make such hardness gradients could revolutionize engineering anywhere that 'interfaces between soft and hard materials [are required].' One of the first applications researchers envision is prosthetic limbs."

A number of readers let us know about the Chaos Computer Club's latest caper: they published the fingerprint of German Secretary of the Interior Wolfgang Schäuble (link is to a Google translation of the German original). The club has been active in opposition to Germany's increasing push to use biometrics in, for example, e-passports. Someone friendly to the club's aims captured Schäuble's fingerprint from a glass he drank from at a panel discussion. The club published 4,000 copies of their magazine Die Datenschleuder including a plastic foil reproducing the minister's fingerprint — ready to glue to someone else's finger to provide a false biometric reading. The CCC has a page on their site detailing how to make such a fake fingerprint. The article says a ministry spokesman alluded to possible legal action against the club.
