US DOE Sets Sights On 300 Petaflop Supercomputer

dcblogs writes U.S. officials Friday announced plans to spend $325 million on two new supercomputers, one of which may eventually be built to support speeds of up to 300 petaflops. The U.S. Department of Energy, the major funder of supercomputers used for scientific research, wants to have the two systems – each with a base speed of 150 petaflops – possibly running by 2017. Going beyond the base speed to reach 300 petaflops will take additional government approvals. If the world stands still, the U.S. may conceivably regain the lead in supercomputing speed from China with these new systems. How adequate this planned investment will look three years from now is a question. Lawmakers weren’t reading from the same script as U.S. Energy Secretary Ernest Moniz when it came to assessing the U.S.’s place in the supercomputing world. Moniz said the awards “will ensure the United States retains global leadership in supercomputing.” But Rep. Chuck Fleischmann (R-Tenn.) put U.S. leadership in the past tense. “Supercomputing is one of those things that we can step up and lead the world again, ” he said.

81% of Tor Users Can Be De-anonymized By Analysing Router Information

An anonymous reader writes A former researcher at Columbia University’s Network Security Lab has conducted research since 2008 indicating that traffic flow software included in network routers, notably Cisco’s ‘Netflow’ package, can be exploited to deanonymize 81.4% of Tor clients. Professor Sambuddho Chakravarty, currently researching Network Anonymity and Privacy at the Indraprastha Institute of Information Technology, uses a technique which injects a repeating traffic pattern into the TCP connection associated with an exit node, and then compares subsequent aberrations in network timing with the traffic flow records generated by Netflow (or equivalent packages from other router manufacturers) to individuate the ‘victim’ client. In laboratory conditions the success rate of this traffic analysis attack is 100%, with network noise and variations reducing efficiency to 81% in a live Tor environment. Chakravarty says: ‘it is not even essential to be a global adversary to launch such traffic analysis attacks. A powerful, yet non- global adversary could use traffic analysis methods [] to determine the various relays participating in a Tor circuit and directly monitor the traffic entering the entry node of the victim connection.’ Read more of this story at Slashdot.

An Applied Investigation Into Graphics Card Coil Whine

jones_supa writes We all are aware of various chirping and whining sounds that electronics can produce. Modern graphics cards often suffer from these kind of problems in form of coil whine. But how widespread is it really? Hardware Canucks put 50 new graphics cards side-by-side to compare them solely from the perspective of subjective acoustic disturbance. NVIDIA’s reference platforms tended to be quite well behaved, just like their board partners’ custom designs. The same can’t be said about AMD since their reference R9 290X and R9 290 should be avoided if you’re at all concerned about squealing or any other odd noise a GPU can make. However the custom Radeon-branded SKUs should usually be a safe choice. While the amount and intensity of coil whine largely seems to boil down to luck of the draw, at least most board partners are quite friendly regarding their return policies concerning it.

R. A. Montgomery, Creator of the "Choose Your Own Adventure" Books, Dead At 78

Dave Knott writes Raymond Almiran Montgomery, original publisher and author of the incredibly popular “Choose Your Own Adventure” book series for children, the 4th bestselling children’s series of all time, has died at the age of 78. In 1975, Montgomery founded a small press and when, in 1977, Ed Packard submitted an innovative book for young readers, “Sugarcane Island”, Montgomery immediately saw it for what it was: a role-playing game in book form. He leapt at the chance to publish it, and launched a series, writing the second book, “Journey Under The Sea”, himself. When Montgomery went through a divorce and sold his stake in the press to his ex-wife, he took the series, renamed as “Choose Your Own Adventure”, to Bantam. The books went on to sell more than 250 million copies across 230 titles in 40 languages. Montgomery’s interests also extended to new technology, adapting the series to the Atari console in 1984. He was also responsible for the Comic Creator software on Apple’s Macintosh computers. Montgomery died on November 9th. The cause of death was not disclosed. Read more of this story at Slashdot.
