ARM TrustZone Hacked By Abusing Power Management

2017-09-24T13:30:00+00:00

"This is brilliant and terrifying in equal measure," writes the Morning Paper. Long-time Slashdot reader phantomfive writes: Many CPUs these days have DVFS (Dynamic Voltage and Frequency Scaling), which allows the CPU's clockspeed and voltage to vary dynamically depending on whether the CPU is idling or not. By turning the voltage up and down with one thread, researchers were able to flip bits in another thread. By flipping bits when the second thread was verifying the TrustZone key, the researchers were granted permission. If number 'A' is a product of two large prime numbers, you can flip a few bits in 'A' to get a number that is a product of many smaller numbers, and more easily factorable. "As the first work to show the security ramifications of energy management mechanisms," the researchers reported at Usenix, "we urge the community to re-examine these security-oblivious designs."

Inside Amazon's Warehouses: Thousands of Senior Citizens and the Occasional Robot Mishap

2017-09-24T01:30:00+00:00

Amazon aggressively recruited thousands of retirees living in mobile homes to migrate to Amazon's warehouses for seasonal work, according to a story shared by nightcats. Wired reports:From a hiring perspective, the RVers were a dream labor force. They showed up on demand and dispersed just before Christmas in what the company cheerfully called a "taillight parade." They asked for little in the way of benefits or protections. And though warehouse jobs were physically taxing -- not an obvious fit for older bodies -- recruiters came to see CamperForce workers' maturity as an asset. These were diligent, responsible employees. Their attendance rates were excellent. "We've had folks in their eighties who do a phenomenal job for us," noted Kelly Calmes, a CamperForce representative, in one online recruiting seminar... In a company presentation, one slide read, "Jeff Bezos has predicted that, by the year 2020, one out of every four workampers in the United States will have worked for Amazon." The article is adapted from a new book called "Nomadland," which also describes seniors in mobile homes being recruited for sugar beet harvesting and jobs at an Iowa amusement park, as well as work as campground hsots at various national parks. Many of them "could no longer afford traditional housing," especially after the financial downturn of 2008. But at least they got to hear stories from their trainers at Amazon about the occasional "unruly" shelf-toting "Kiva" robot: They told us how one robot had tried to drag a worker's stepladder away. Occasionally, I was told, two Kivas -- each carrying a tower of merchandise -- collided like drunken European soccer fans bumping chests. And in April of that year, the Haslet fire department responded to an accident at the warehouse involving a can of "bear repellent" (basically industrial-grade pepper spray). According to fire department records, the can of repellent was run over by a Kiva and the warehouse had to be evacuated.

Apple: iPhones Are Too 'Complex' To Allow Unauthorized Repair

2017-09-23T10:00:00+00:00

Jason Koebler writes: Apple's top environmental officer made the company's most extensive statements about the repairability of Apple hardware on Tuesday: "Our first thought is, 'You don't need to repair this.' When you do, we want the repair to be fairly priced and accessible to you," Lisa Jackson, Apple's vice president of policy and social initiatives said at TechCrunch Disrupt in San Francisco. "To think about these very complex products and say the answer to all our problems is that you should have anybody to repair and have access to the parts is not looking at the whole problem." Apple has lobbied against "Fair Repair" bills in 11 states that would require the company to make its repair guides available and to sell replacement parts to the general public. Instead, it has focused on an "authorized service provider" model that allows the company to control the price and availability of repair.

Super-Accurate GPS Chips Coming To Smartphones In 2018

2017-09-23T07:00:00+00:00

schwit1 writes about a new mass-market Broadcom chip designed for the next generation of smartphones: It'll know where you are to within 30 centimeters (11.8 inches), rather than five meters. At least that's the claim chip maker Broadcom is making. It says that some of its next-generation smartphone chips will use new global positioning satellite signals to boost accuracy. In a detailed report on the announcement and how the new signals work, IEEE Spectrum says that the new chips, which are expected to appear in some phones as soon as next year, will also use half the power of today's chips and even work in cities where tower blocks often interfere with existing systems. All told, it sounds like a massive change for those who rely on their phones to find their way.

Court Rules That Imported Solar Panels Are Bad For US Manufacturing

2017-09-23T01:25:00+00:00

The International Trade Commission has ruled that American companies are being hurt by cheap solar panels from overseas, providing an opportunity for President Donald Trump to tax imports from countries like China. The Verge reports: Today's unanimous decision ruled that the companies SolarWorld Americans and Suniva were struggling financially not because of their own poor management, but because they couldn't compete with cheap panels from countries like China, Mexico, and South Korea. Suniva is now suggesting import duties of 40 cents a watt for solar cells, and a floor price of 78 cents a watt for panels. (Right now, the average floor price, worldwide, for panels is about 32 cents.) The Solar Energy Industries Association warned that implementing these suggestions could end up doubling the price of solar, thus destroying demand and causing Americans to lose their jobs.

A New Zealand Company Built An AI Baby That Plays the Piano

2017-09-22T10:00:00+00:00

pacopico writes: A New Zealand company called Soul Machines has built a disturbingly lifelike virtual baby powered by artificial intelligence software. According to a Bloomberg story, the baby has learned to read books, play the piano and draw pictures. The work is built off the research of Mark Sagar, the company's CEO, who is on a quest to mimic human consciousness in a machine. Sagar used to work at Weta creating lifelike faces for films like King Kong and Avatar and is now building these very realistic looking virtual avatars and pumping them full of code that not only handles things like speech but that also replicates the nervous system and brain function. The baby, for example, has virtual dopamine receptors that fire when it feels joy from playing the piano. What could go wrong?

Ford Is Using Microsoft's HoloLens To Design Cars In Augmented Reality

2017-09-22T00:05:00+00:00

Ford is using Microsoft's HoloLens headset to let designers quickly model out changes to cars, trucks, and SUVs in augmented reality. This allows designers to see the changes on top of an existing physical vehicle, instead of the traditional clay model approach to car design. The Verge reports: Ford is still using clay models, but the HoloLens can be used to augment additional 3D models without having to build every single design prototype with clay. It's one of the more interesting ways we've seen businesses use Microsoft's HoloLens, and it's something customers will never see. Microsoft is planning to hold a Windows Mixed Reality launch event on October 3rd in San Francisco. We're not expecting to hear about a HoloLens successor, but we should get a better idea of what apps and games we'll see coming for Microsoft's Windows Mixed Reality headsets.

Tesla Is Working With AMD To Develop Its Own AI Chip For Self-Driving Cars

2017-09-21T13:00:00+00:00

An anonymous reader quotes a report from CNBC: Tesla is getting closer to having its own chip for handling autonomous driving tasks in its cars. The carmaker has received back samples of the first implementation of its processor and is now running tests on it, said a source familiar with the matter. The effort to build its own chip is in line with Tesla's push to be vertically integrated and decrease reliance on other companies. But Tesla isn't completely going it alone in chip development, according to the source, and will build on top of AMD intellectual property. On Wednesday Sanjay Jha, CEO of AMD spin-off GlobalFoundries, said at the company's technology conference in Santa Clara, California, that the company is working directly with Tesla. GlobalFoundries, which fabricates chips, has a wafer supply agreement in place with AMD through 2020. Tesla's silicon project is bounding ahead under the leadership of longtime chip architect Jim Keller, the head of Autopilot hardware and software since the departure of Apple veteran Chris Lattner in June. Keller, 57, joined Tesla in early 2016 following two stints at AMD and one at Apple. Keller arrived at Apple in 2008 through its acquisition of Palo Alto Semiconductor and was the designer of Apple's A4 and A5 iPhone chips, among other things. More than 50 people are working on the initiative under Keller, the source said. Tesla has brought on several AMD veterans after hiring Keller, including director Ganesh Venkataramanan, principal hardware engineer Bill McGee and system circuit design lead Dan Bailey.

Scientists Create World's First 'Molecular Robot' Capable of Building Molecules

2017-09-21T07:00:00+00:00

New submitter re385 shares a report from Science Magazine: Scientists at The University of Manchester have created the world's first "molecular robot" that is capable of performing basic tasks including building other molecules. The tiny robots, which are a millionth of a millimeter in size, can be programmed to move and build molecular cargo, using a tiny robotic arm. Each individual robot is capable of manipulating a single molecule and is made up of just 150 carbon, hydrogen, oxygen and nitrogen atoms. To put that size into context, a billion billion of these robots piled on top of each other would still only be the same size as a single grain of salt. The robots operate by carrying out chemical reactions in special solutions which can then be controlled and programmed by scientists to perform the basic tasks. In the future such robots could be used for medical purposes, advanced manufacturing processes and even building molecular factories and assembly lines. The research will be published in Nature on Thursday 21st September. "All matter is made up of atoms and these are the basic building blocks that form molecules," explains Professor David Leigh, who led the research at University's School of Chemistry. "Our robot is literally a molecular robot constructed of atoms just like you can build a very simple robot out of Lego bricks. The robot then responds to a series of simple commands that are programmed with chemical inputs by a scientist. It is similar to the way robots are used on a car assembly line. Those robots pick up a panel and position it so that it can be riveted in the correct way to build the bodywork of a car. So, just like the robot in the factory, our molecular version can be programmed to position and rivet components in different ways to build different products, just on a much smaller scale at a molecular level."

Google Buys Part of HTC's Smartphone Team For $1.1 Billion

2017-09-21T05:00:00+00:00

BrianFagioli shares a report from BetaNews: Today, a deal finally happens, but Google didn't buy HTC outright. Strangely, as the deal is laid out, the search giant has seemingly bought HTC employees. Yes, for $1.1 billion, the search giant has sort of purchased human beings -- plus it gets access to some intellectual property. HTC gets a much-needed big influx of cash. "Google and HTC Corporation today announced a definitive agreement under which certain HTC employees -- many of whom are already working with Google to develop Pixel smartphones -- will join Google. HTC will receive $1.1 billion in cash from Google as part of the transaction. Separately, Google will receive a non-exclusive license for HTC intellectual property (IP). The agreement is a testament to the decade-long strategic relationship between HTC and Google around the development of premium smartphones," says HTC.

China Arms Upgraded Tianhe-2A Hybrid Supercomputer

2017-09-21T01:40:00+00:00

New submitter kipperstem77 shares an excerpt from a report via The Next Platform: The National University of Defense Technology (NUDT) has, according to James Lin, vice director for the Center of High Performance Computing (HPC) at Shanghai Jiao Tong University, who divulged the plans last year, is building one of the three pre-exascale machines [that China is currently investing in], in this case a kicker to the Tianhe-1A CPU-GPU hybrid that was deployed in 2010 and that put China on the HPC map. This exascale system will be installed at the National Supercomputer Center in Tianjin, not the one in Guangzhou, according to Lin. This machine is expected to use ARM processors, and we think it will very likely use Matrix2000 DSP accelerators, too, but this has not been confirmed. The second pre-exascale machine will be an upgrade to the TaihuLight system using a future Shenwei processor, but it will be installed at the National Supercomputing Center in Jinan. And the third pre-exascale machine being funded by China is being architected in conjunction with AMD, with licensed server processor technology, and which everyone now thinks is going to be based on Epyc processors and possibly with Radeon Instinct GPU coprocessors. The Next Platform has a slide embedded in its report "showing the comparison between Tianhe-2, which was the fastest supercomputer in the world for two years, and Tianhe-2A, which will be vying for the top spot when the next list comes out." Every part of this system shows improvements.

Amazon Is Reportedly Working On Alexa-Enabled Smart Glasses

2017-09-20T22:40:00+00:00

According to the Financial Times (Warning: source paywalled), Amazon is working on building a pair of smart glasses to house its Alexa voice assistant. The report also mentions a home security camera that is in the works, capable of linking up to Amazon's existing Echo connected devices. TechCrunch reports: According to the FT, the smart glasses are intended to be purely an earbuds-free housing for Amazon's Alexa AI -- with a bone-conduction audio system that would enable the wearer to hear Alexa without the need to be wired in. The FT reports the glasses would wirelessly tether to a user's smartphone for connectivity. They are also apparently being designed to look like a regular pair of spectacles, so they could be worn comfortably and unobtrusively. The paper notes that Amazon hired Babak Parviz, founder of Google Glass, in 2014, and says he's been closely involved in the project. It also points to several other Glass researchers, engineers and designers having moved to Amazon's labs -- per analysis of their LinkedIn profiles.

AMD Opteron Vs EPYC: How AMD Server Performance Evolved Over 10 Years

2017-09-20T22:00:00+00:00

New submitter fstack writes: Phoronix has carried out tests comparing AMD's high-end EPYC 7601 CPU to AMD Opteron CPUs from about ten years ago, looking at the EPYC/Opteron Linux performance and power efficiency. Both on the raw performance and performance-per-Watt, the numbers are quite staggering though the single-threaded performance hasn't evolved quite as much. The EPYC 7601 is a $4,200 USD processor with 32 cores / 64 threads. The first of many tests was with NAS Parallel Benchmarks: "For a heavily threaded test like this, going from a single Opteron 2300 series to the EPYC 7601 yielded around a 40x increase in performance," reports Phoronix. "Not bad when also considering it was only a 16x increase in the thread count (4 physical cores to 32 cores / 64 threads). The EPYC 7601 has a lower base clock frequency than the Opteron 2300 CPUs tested but has a turbo/boost frequency higher, among many architectural advantages over these K10 Opterons. With the NASA test's Lower-Upper Gauss-Seidel solver, going from the dual Opteron 2384 processors to a single EPYC 7601 yields around a 25x improvement in performance over the past decade of AMD server CPUs. Or in looking at the performance-per-Watt with the LU.C test, it's also around a 25x improvement over these older Opterons."

Hurricane Maria Knocks Out Power To Entire Island of Puerto Rico

2017-09-20T19:45:00+00:00

An anonymous reader writes: Hurricane Maria's eye has left Puerto Rico, but the mammoth storm is still lashing the island with devastating winds. Maria weakened to a Category 3 hurricane Wednesday afternoon, hurling winds of 115 mph. But hurricane-force gusts topping 74 mph still extend over much of Puerto Rico, the National Hurricane Center said. Maria's brute force wiped out electricity to the entire island. "We are 100% without power," a spokesman for the Puerto Rico governor's office said Wednesday. The storm also ripped trees out of the ground and caused widespread flooding. "This is total devastation," said Carlos Mercader, a spokesman for Puerto Rico's governor. "Puerto Rico, in terms of the infrastructure, will not be the same. ... This is something of historic proportions." Maria is expected to dump a total of 12 to 18 inches of rain on Puerto Rico before barreling toward the Dominican Republic starting Wednesday night.

Is the World Ready For Flying Cars?

2017-09-20T03:30:00+00:00

An anonymous reader shares a report from TechCrunch, adding: "Is the world ready for flying cars? Sebastian Thrun, the supposed godfather of autonomous driving, and several other tech investors seem to think so." From the report: At TechCrunch Disrupt SF 2017, Thrun talked a lot about flying cars and how that was the future of transportation. So did GGV's Jenny Lee, a prolific investor in China. And so did Steve Jurvetson, one of the original investors in SpaceX. The technical backbone for flying cars seems to be there already -- with drones becoming ever-present and advancements in AI and self-driving cars -- but the time is coming soon that flying cars will be the primary mode of transportation. "I can't envision a future of highways [and being] stuck in cars," Thrun said. "I envision a [future] where you hop in a thing, go in the air, and fly in a straight line. I envision a future where Amazon delivers my food in the air in five minutes. The air is so free of stuff and is so unused compared to the ground, it has to happen in my opinion." Cars today are forced to move on a two-dimensional plane (ramps, clover intersections and tunnels set aside), and while self-driving cars would make it easier for cars to talk to each other and move more efficiently, adding a third dimension to travel would make a lot of sense coming next. Thrun pointed to airplane transit, which is already a "fundamentally great mass transit system." Jurvetson said he was actually about to ride in a flying car before he "watched it flip over" before arriving to talk about some of the next steps in technology onstage. So, there's work to be done there, but it does certainly seem that all eyes are on flying cars. And that'll be enabled by autonomous driving, which will probably allow flying cars to figure out the most efficient paths from one point to the next without crashing into each other. Lee said that China is closely analyzing changes in transportation, which might end up leading to flying cars. "I do want to highlight that there's going to be huge disruption within the transportation ecosystem in China," Lee said. "Cars going from diesel to electric. China has about 200 million install base of car ownership. In 2016, only 1 million cars are electric. The Chinese government hopes to install 5 million parking lots that are electric... Even the Chinese OEMs are buying into flying taxis."
