An On-Demand Vending Machine That Chills Drinks in Just 45 Seconds

When you think about it, keeping a fridge full of drinks perpetually cold at a store is a tremendous waste of energy given the product may not be sold for days. But the only alternate solution is to somehow chill drinks at the time of purchase, which is exactly what a new refrigeration technology called V-Tex does—without the need for gallons of liquid nitrogen.

A Little-Heralded New iOS 7 Feature: Multipath TCP

Olivier Bonaventure writes “Besides changes in UI, multitasking and other features that the press discusses, iOS7 also includes support for Multipath TCP. Multipath TCP is a major extension to TCP that is able to use different interfaces for the same connection. Until now, Multipath TCP has been mainly used by researchers with a modified Linux kernel. iOS7 changes that, with millions of Multipath-TCP enabled devices that can switch from 3G to WiFi without losing existing TCP connections. This is not yet the case on iOS7, which currently seems to only enable it for SIRI, but other use cases will likely appear in the future.” Read more of this story at Slashdot.

The ten fastest supercomputers on the planet, in pictures

A Chinese supercomputer known as Tianhe-2 was today named the world’s fastest machine, nearly doubling the previous speed record with its performance of 33.86 petaflops. Tianhe-2’s ascendance was revealed in advance  and was made official today with the release of the new Top 500 supercomputer list . Tianhe-2 was developed at China’s National University of Defense Technology and will be deployed in the country’s National Supercomputing Center before the end of this year. “The surprise appearance of Tianhe-2, two years ahead of the expected deployment, marks China’s first return to the No. 1 position since November 2010, when Tianhe-1A was the top system,” the Top 500 announcement states. “Tianhe-2 has 16,000 nodes, each with two Intel Xeon Ivy Bridge processors and three Xeon Phi processors for a combined total of 3,120,000 computing cores.” The combined performance of the 500 systems on the list is 223 petaflops, up from 162 petaflops in the previous list released six months ago. A petaflop represents one quadrillion floating point operations per second, or a million billion.

Tesla Motors Repays $465M Government Loan 9 Years Early

Tesla Motors announced today it has completely repaid the $465 million loan from the U.S. Department of Energy the company received in 2010. The funds were generated by Tesla through a recent sale of their stock, worth close to a billion dollars. The stock price had risen sharply after the company reported its first profitable quarter (and the stock still sits roughly 50% higher than before their earnings release). Today’s payment of $451.8 million finished off both the loan’s principal and its interest, nine years before the final payment was due. Tesla CEO Elon Musk said, ‘I would like to thank the Department of Energy and the members of Congress and their staffs that worked hard to create the ATVM program, and particularly the American taxpayer from whom these funds originate. I hope we did you proud.’ Read more of this story at Slashdot.

U.S. Offshore Wind Farm Receives $2 Billion From Japanese Banks

kkleiner writes “The Bank of Tokyo has invested $2 billion into Cape Wind, the 130-turbine wind farm that is inching closer to becoming a reality. The project is vying to the first offshore wind farm in the U.S. after a decade-long campaign mired by red tape in order to receive approval. Proposed to be installed in Nantucket Sound, the wind farm is estimated to have a capacity of 468 megawatts.” Read more of this story at Slashdot.

Google Fiber is officially coming to Austin, Texas

Hear that? It’s Austin, being weird enough to add yet another reason to live within its city limits. As rumored , Google Fiber will be rolling down to one of Texas’ most esteemed towns in the near future, joining the Kansas City, Kansas and Missouri metro as the only locales (so far) in the US of A offering the outfit’s Fiber-based TV, phone and 1Gbps broadband services. Mum’s the word on an exact rollout, but we’ll update this post as we learn more. Filed under: Internet , HD , Google Comments Source: Gig.U

California’s Surreal Retroactive Tax On Tech Startup Investors

waderoush writes “Engineers and hackers don’t think much about tax policy, but there’s a bizarre development in California that they should know about, since it could reduce the pool of angel-investment money available for tech startups. Under a tax break available since the 1990s, startup founders and other investors in California were allowed to exclude or defer their gains when they sold stock in California-based small businesses. Last year, a California appeals court ruled that the tax break was unconstitutional, since it discriminated against investors in out-of-state companies. Now the Franchise Tax Board, California’s version of the IRS, has issued a notice saying how it intends to implement the ruling — and it’s a doozie. Not only is the tax break gone, but anyone who claimed an exclusion or deferral on the sale of small-business stock since 2008 is about to get a big retroactive tax bill. Investors, entrepreneurs, and even the plaintiffs in the original lawsuit are up in arms about the FTB’s notice, saying that it goes beyond the court’s intent and that it will drive investors out of the state. This Xconomy article takes an in-depth look at the history of the court case, the FTB’s ruling, and the reaction in the technology and investing communities.” Read more of this story at Slashdot.

Flexible Circuits By the Slice

MTorrice writes “Researchers have demonstrated a way to make high performance, flexible integrated circuits using almost exclusively standard equipment and materials already needed to make conventional chips. Such a method could allow electronics manufacturers to build new devices, such as smart medical implants and flexible displays, without needing to significantly overhaul current production protocols. The method, developed by researchers at the University of Texas, Austin, started with researchers patterning integrated circuits on silicon wafers using a standard production line. They then cut off the top 20 to 30 micrometers of the wafer using a thin wire—like slicing a block of cheese—to produce a thin, flexible platter of circuits.” Read more of this story at Slashdot.
