Google’s Tensor Processing Unit Could Advance Moore’s Law 7 Years Into The Future

An anonymous reader writes from a report via PCWorld: Google says its Tensor Processing Unit (TPU) advances machine learning capability by a factor of three generations. “TPUs deliver an order of magnitude higher performance per watt than all commercially available GPUs and FPGA, ” said Google CEO Sundar Pichai during the company’s I/O developer conference on Wednesday. The chips powered the AlphaGo computer that beat Lee Sedol, world champion of the game called Go. “We’ve been running TPUs inside our data centers for more than a year, and have found them to deliver an order of magnitude better-optimized performance per watt for machine learning. This is roughly equivalent to fast-forwarding technology about seven years into the future (three generations of Moore’s Law), ” said Google’s blog post. “TPU is tailored to machine learning applications, allowing the chip to be more tolerant of reduced computational precision, which means it requires fewer transistors per operation. Because of this, we can squeeze more operations per second into the silicon, use more sophisticated and powerful machine learning models, and apply these models more quickly, so users get more intelligent results more rapidly.” The chip is called the Tensor Processing Unit because it underpins TensorFlow, the software engine that powers its deep learning services under an open-source license.

Backblaze Releases Billion-Hour Hard Drive Reliability Report

jones_supa writes: The storage services provider Backblaze has released its reliability report for Q1/2016 covering cumulative failure rates of mechanical hard disk drives by specific model numbers and by manufacturer. The company noted that as of this quarter, its 60, 000 drives have cumulatively spun for over one billion hours (100, 000 years). Hitachi Global Storage Technologies (HGST) is the clear leader here, with an annual failure rate of just 1% for three years running. The second position is also taken by a Japanese company: Toshiba. Third place goes to Western Digital (WD), with the company’s ratings having improved in the past year. Seagate comes out the worst, though it is suspected that much of that rating was warped by the company’s crash-happy 3 TB drive (ST3000DM001). Backblaze notes that 4 TB drives continue to be the sweet spot for building out its storage pods, but that it might move to 6, 8, or 10 TB drives as the price on the hardware comes down.

Developer Of Anonymous Tor Software Dodges FBI, Leaves US

An anonymous reader quotes a report from CNN: FBI agents are currently trying to subpoena one of Tor’s core software developers to testify in a criminal hacking investigation, CNNMoney has learned. But the developer, who goes by the name Isis Agora Lovecruft, fears that federal agents will coerce her to undermine the Tor system — and expose Tor users around the world to potential spying. That’s why, when FBI agents approached her and her family over Thanksgiving break last year, she immediately packed her suitcase and left the United States for Germany. “I was worried they’d ask me to do something that hurts innocent people — and prevent me from telling people it’s happening, ” she said in an exclusive interview with CNNMoney. Earlier in the month, Tech Dirt reported the Department of Homeland Security wants to subpoena the site over the identity of a hyperbolic commenter. Read more of this story at Slashdot.

Acura introduces a sleeker self-driving test car

As we creep ever closer to an autonomous-car future , one thing is for certain, most of the driverless cars we see being tested look hideous thanks to all the sensors strapped to the roof. Today Acura introduced its second generation Automated Acura RLX Development Vehicle with updated sensors and a more pleasing aesthetic. Gone is the spinning LIDAR system replaced with a more compact and robust version of the light detection and ranging technology. It’s also got updated RADAR, camera, GPS and higher performance GPUs and CPUs as well as what Acura is calling “more intelligent software algorithms to support more complex testing scenarios.” Acura and its parent company Honda have been testing autonomous cars at its GoMentum Station in the Bay Area since last year with a specially outfitted RLX (shown in the video below with the spinning LIDAR system). This new car will replace that vehicle.

Scientists made see-through wood that’s stronger than glass

Researchers at the University of Maryland were able pull away color and chemicals from a block of wood to leave it impressively see-through. The result is a material that is both stronger and more insulating than glass, with better biodegradability than plastic. “We were very surprised by how transparent it could go, ” said Liangbing Hu, who wrote about the project in Advanced Materials . Hu’s team isn’t the only group that’s developed a technique for transparent wood — Swedish researchers have also been able to clear out that pesky visible pulp, replacing it with a transparent polymer. The treatment techniques appear pretty similar: it’s a two-stage process. The researchers first boiled the wood in water, sodium hydroxide and other chemicals for roughly two hours. This flushes out lignin, the molecule responsible for giving wood its color. The team then poured epoxy over the block which makes the wood four to five times stronger, although it makes it all a little less environmentally-friendly in the process. One of the great properties of the treated wood is how it retains the structure and natural channels from when it was a tree. These micro-channels can then deliver light similarly to how it moved nutrients around as part of a plant. “In traditional material the light gets scattered, ” said Hu. “If you have this waveguide effect with wood, more light comes into your house.” So what’s stopping us living in see-through wood houses, aside from privacy issues? Size limitations. Five by five-inch wood blocks are as large as they’ve been able to make it work, ranging in thickness from paper thin to about a centimeter thick — far more substantial than what Swedish researchers have shown off so far. Dr. Hu and the University of Maryland scientists are is still working to scale it up further. If the team can accomplish that there’s no shortage of applications, ranging from windows, building materials and furniture to smaller, precise, optical equipment that’s normally made from glass or plastic.

Hidden FBI Microphones Exposed In California

An anonymous reader writes: “Federal agents are planting microphones to secretly record conversations, ” reports CBS Local, noting that for 10 months starting in 2010, FBI agents hid microphones inside light fixtures, and also at a bus stop outside the Oakland Courthouse, to record conversations without a warrant. “They put microphones under rocks, they put microphones in trees, they plant microphones in equipment, ” a security analyst and former FBI special agent told CBS Local. “I mean, there’s microphones that are planted in places that people don’t think about, because thats the intent!” Federal authorities are currently investigating fraud and bid-rigging charges against a group of real estate investors, and the secret recordings came to light when they were submitted as evidence. “Private communication in a public place qualifies as a protected ‘oral communication’…” says one of the investor’s lawyers, “and therefore may not be intercepted without judicial authorization.” Read more of this story at Slashdot.

890 College Students Sue Google Over Email Scanning

An anonymous reader quotes this report from Bay Area Newsgroup: Legal action against Google by four UC Berkeley students has ballooned into two lawsuits by 890 U.S. college students and alumni alleging the firm harvested their data for commercial gain without their consent…making the same claim: that Google’s Apps for Education, which provided them with official university email accounts to use for school and personal communication, allowed Google until April 2014 to scan their emails without their consent for advertising purposes…. The suit by 710 students alleged that until April 2015, Google denied it was scanning students’ emails for advertising purposes and misled schools into believing the emails were private. The students’ lawyers say each student is seeking a maximum of $10, 000, while the U.S. District Court Judge Lucy Koh told the lawyer that “Our clerk’s office is really unhappy you are circumventing our [$400 per case] filing fees by adding 710 cases under one case number.” Read more of this story at Slashdot.

Ethical Hackers Donate 1,000,000 Air Miles To Charity

An anonymous reader writes:Certified ethical hackers at Offensi.com identified a bug allowing remote code execution on one of United Airlines’ sites, and submitted their findings to the airline’s “bug bounty” program. After a fix was placed into production, their team was awarded 1, 000, 000 Mileage Plus air miles, which they say was accompanied by an email informing them that the IRS would consider their award as $20, 000 of taxable income. “If after evaluating the taxable amount you choose not to accept your award, you are also able to donate your award to charity, ” the e-mail explained. The hackers ultimately chose to distribute their air miles among three charities — the Ronald McDonald house, the Muscular Dystrophy Association, and the Casa de Esperanza de los Ninos Organization. Another security researcher complained in November that United failed to close a serious vulnerability he’d identified for almost six months. Read more of this story at Slashdot.

Fitness App Runkeeper Secretly Tracks Users At All Times, Sends Data to Advertisers

An anonymous reader writes: FitnessKeeper, the company behind running app Runkeeper, is in hot water in Europe. The company has received a formal complaint from the Norwegian Consumer Council for breaching European data protection laws. But why? Runkeeper tracks its users’ location at all times — not just when the app is active — and sends that data to advertisers. The NCC, a consumer rights watchdog, is conducting an investigation into 20 apps’ terms and conditions to see if the apps do what their permissions say they do and to monitor data flows. Tinder has already been reported to the Norwegian data protection authority for similar breaches of privacy laws. The NCC’s investigation into Runkeeper discovered that user location data is tracked around the clock and gets transmitted to a third party advertiser in the U.S. called Kiip.me.Finn Myrstad, the council’s digital policy director, said: We checked the apps technically, to see the data flows and to see if the apps actually do what they say they do. Everyone understands that Runkeeper tracks users while they exercise, but to continue after the training has ended is not okay. Not only is it a breach of privacy laws, we are also convinced that users do not want to be tracked in this way, or for information to be shared with third party advertisers.
