Submission + - Sun to build 62,976 core Opteron SuperComputer (wired.com)

mytrip writes: "Sun Microsystems announced today that its hardware will power the largest supercomputer ever built, weighing in with 62,976 CPU cores, 125 terabytes of memory, 1.7 terabytes of disk space, and 504 teraflops of performance.

The computer, which has been dubbed "Ranger," will be hosted at the Texas Advanced Computing Center at the University of Texas, Austin. It is due to go online on January 1, 2008.

Ranger costs $30 million in hardware alone, and an additional $29 million for staffing and maintenance — and is being entirely funded by a grant from the National Science Foundation.

Under the hood, Ranger's brain will be built from 16,744 quad-core AMD Opteron processors. The machine's production timeline is dependent on how fast AMD can crank out the as-yet-unreleased chips, Bechtolsheim said."

Submission + - UW says it will aid RIAA (thenewstribune.com)

arlanTLDR writes: The University of Washington announced that it will not only comply with the RIAA, it will outright aid them in finding students accused of illegal file sharing. A letter from the Vice Provost for Student Life sent to all students indicates that "The University has been notified by the RIAA that we will be receiving a number of these early settlement letters. After careful consideration, we have decided to forward the letters to the alleged copyright violators."

Submission + - Giant microwave turns plastic back to oil (newscientist.com) 1

CarrieSmith writes: "A US company is taking plastics recycling to another level — turning them back into the oil they were made from, and gas. All that is needed, claims Global Resource Corporation (GRC), is a finely tuned microwave and — hey presto! — a mix of materials that were made from oil can be reduced back to oil and combustible gas (and a few leftovers). The story includes a video demonstrating how pulverised tyres are reduced to oil, gas, and carbon black — a powder used to make inks and dyes. http://environment.newscientist.com/channel/earth/ dn12141"

Submission + - Mozilla gives details on Firefox 3 changes (vnunet.com)

99luftballon writes: "Vnunet has an interview with the development team of Firefox 3 which shows the main features of the new browser. Top of the list is a new graphics engine with improved rendering and zoom capability but it's the plans for changing the bookmarking system into a SQL database that looks most interesting. Also telling is the refusal to give a launch date, with the head of Mozilla Europe frankly stating "We do not want to ship crap on time." Wonder who he could be referring to."

Submission + - A robot that travels through the body

Roland Piquepaille writes: "The reference to the 1966 movie "Fantastic Voyage" is maybe too obvious. But Israeli scientists have developed a 1-millimeter-diameter medical robot that will be able to crawl within our veins and arteries. It's too early to know when this medical robot is allowed to explore a real human being. But the researchers think it could be used to fight some cancers. They even envision groups of robots working simultaneously to fight metastases. Read more for some details and a picture of what the tiny submarine robot would look like."

Submission + - Human presence linked to Corel Reef deaths

cagrin writes: From the article: "Scientists have known for years that humans are killing corals indirectly and directly through global warming, overfishing and pollution. Many reefs off populous coasts have been decimated, while those near uninhabited areas are often thriving. "For some reason, when you put people next to reefs, they die," said microbiologist Forest Rohwer of San Diego State University at a recent symposium at the American Museum of Natural History here. A 2004 study found that 70 percent of the world's reefs had been destroyed or were threatened by global warming and other human activities." Link: Herpes Virus Killing Coral Reefs

Submission + - Day of Silence on the Internet (damontimm.com)

thornomad writes: "Time to pick up the phone (or usb headset) and call a representative or two: pandora.com (and other internet radio sites) has gone silent for the day to protest the impending legistlation that will effect internet radio:

Hi, it's Tim from Pandora, I'm sorry to say that today Pandora, along with most Internet radio sites, is going off the air in observance of a Day Of Silence. We are doing this to bring to your attention a disastrous turn of events that threatens the existence of Pandora and all of internet radio. We need your help. Ignoring all rationality and responding only to the lobbying of the RIAA, an arbitration committee in Washington DC has drastically increased the licensing fees Internet radio sites must pay to stream songs. Pandora's fees will triple, and are retroactive for eighteen months! Left unchanged by Congress, every day will be like today as internet radio sites start shutting down and the music dies. A bill called the "Internet Radio Equality Act" has already been introduced in both the Senate (S. 1353) and House of Representatives (H.R. 2060) to fix the problem and save Internet radio — and Pandora — from obliteration. I'd like to ask you to call your Congressional representatives today and ask them to become co-sponsors of the bill. It will only take a few minutes and you can find your Congresspersons and their phone numbers by entering your zip code here. Your opinion matters to your representatives — so please take just a minute to call. Visit www.savenetradio.org to continue following the fight to Save Internet Radio. As always, and now more than ever, thank you for your support.

Submission + - Artificial robotic hand with 'air muscles'

morpheus83 writes: A Japanese robot maker on Tuesday unveiled what it called the world's first prototype of an artificial hand with "air muscles" that can do even delicate work like picking up a raw egg. The firm plans to ship some 50 prototypes to research institutes and firms, with plans to market them overseas in the near future.

Submission + - Theoretical parallel computer built for first time (networkworld.com) 1

James McP writes: A working computer has been built that for the first time demonstrates the Parallel Random Access Model (PRAM) of parallel processing. According to the Network World article the unnamed machine uses FPGAs to create sixty four 75Mhz CPUs which have a claimed combined performance of "100x" a normal desktop. The PRAM computer was built as part of a NSF grant that has the goal of developing APIs and compiler optimizations to support the PRAM system. As a bonus, if you submit the winning name for the new PRAM computer you can win $500.

Submission + - Session Hijacking possible in Orkut due to a bug (grok.org.uk)

tomcataxis writes: "A security flaw in Orkut has been disclosed by Susam Pal, Vipul Agarwal and Gauav Mogre which can be exploited to hijack sessions. When a user logs out of Orkut, his session does not expire at the server side. So if an attacker manages to steal the session cookie from another user, he can gain access to the compromised account even after the user has logged out. Cookies can be stolen by persuading users to click on malicious links or run malicious javascript code. The three researchers suggest the users to take the following precautions to protect their accounts from the attackers. 1. One should not run any untrusted JavaScript, program, etc. 2. On a shared system, the user must log out of Orkut by clicking the "Logout" link. This would delete the session cookies at the browser."

Submission + - A potential solution to the black hole information (arxiv.org)

darkstar949 writes: One of the biggest paradoxes in physics is the black hole information paradox, but new research from a team of physicists at Case Western Reserve University may have resolved it. They have purposed that information is not lost in black holes because nothing ever crosses the event horizon, and if this theory is correct then it could be the solution to one of the biggest paradoxes encountered in modern physics.
