Submission + - Algorithm Rates Trustworthiness of Wikipedia Pages

paleshadows writes: Researchers at UCSC developed a tool that measures the trustworthiness of each wikipedia page. Roughly speaking, the algorithm analyzes the entire 7-year user-editing-history and utilzes the longevity of the content to learn which contributors are the most reliable: If your contribution lasts, you gain "reputation", whereas if it's edited out, your reputation falls. The trustworthiness of a newly inserted text is a function of the reputation of all its authors, a heuristic that turned out to be successful in identifying poor content. The interested reader can take a look at this demo (random page with white/orange background marking trusted/untrusted text, respectively; note "random page" link at the left for more demo pages), this presentation (pdf), and this paper (pdf).

Submission + - Infrared radiation: The other wireless technology

StonyandCher writes: Although the recent auctioning of the 700MHz wireless spectrum bands have garnered great interest in the media (not to mention the billions of dollars being thrown around to own some of this), it's not the be-all and end-all answer to our wireless hunger.

New research is starting to be conducted in the area of infrared radiation. Cheap to develop infrastructure for, super fast and with huge amounts of spectrum available (literally many terahertz), is this the unlicensed answer to the dearth of wireless spectrum? This article delves deeper into the world of IR and looks at its pros and foibles.

Submission + - Final AACS key found

julie-h writes: The PowerDVD AACS private key for playing Blu-Ray and HD-DVD's have been found. This was the last key needed. What does this mean? We don't have to sniff/snoop Volume IDs anymore. We can create a program that can decrypt (or play if you will) a disc without any need for WinDVD or PowerDVD. So no sniffing/extracting of keys anymore. And more over: it can work on all platforms... In other words: we can make our own independent, user friendly player (or decrypter).

Submission + - Inflatable mirrors could cut solar cost to $0.29/w

Damien1972 writes: A new technology using inflatable mirrors could dramatically cut the price of solar power to around $0.29 per watt, making the renewable energy source cost competitive with coal and other fossil fuels. The tensegrity-based concentrated photovoltaic system could open up vast areas of the United States for solar farming, whereby farmers could produce both agricultural products and clean energy. The technology has been developed by CoolEarth Solar, based in Livermore, CA.

Submission + - Wikipedia Banned at College

Zatoichi007 writes: "The NYT is reporting that Wikipedia is now being banned as a source for research at Middlebury College. It seems that the last straw for the college occured when students in a Japanese history class wrongly asserted that the Jesuits aided in the Shambara Rebellion, using Wikipedia as the reference point. Is Wikipedia a valid source for "serious" research or just a starting point to find out what might be interesting about a particular topic?"

Submission + - Dell gives desktop Linux its "full attention&#

An anonymous reader writes: Only days after Dell launched a new user feedback forum called Dell Idea Storm where customers can suggest new ideas for the PC manufacturer, the request for a Linux desktop tops the list with thousands of votes. Emails exchanged with Bob Pearson, Dell's vice president of corporate group communications, indicate that Dell is taking the request seriously. Dell is known for taking risks and with its new found devotion to customer service, Dell just might grant the Linux community's wish.
