Tesla Is Working With AMD To Develop Its Own AI Chip For Self-Driving Cars (cnbc.com) 8

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.

How Flying Seriously Messes With Your Mind and Body (bbc.com) 78

dryriver writes: BBC Future has an interesting piece about how traveling in an airliner does strange things to people's minds and bodies, such as far more people starting to cry while watching even mildly emotional movies on airplanes than what is normal, some passengers experiencing decreases in acuity of sight, taste and smell (airline meals are over-seasoned to compensate for this), unusual tiredness or desire to sleep, your skin drying out by up to 37% percent and possibly becoming itchy, and some people breaking wind far more often than they normally would. Here is an excerpt form the report: "There can be no doubt that aircraft cabins are peculiar places for humans to be. They are a weird environment where the air pressure is similar to that atop an 8,000ft-high (2.4km) mountain. The humidity is lower than in some of the world's driest deserts while the air pumped into the cabin is cooled as low as 10C (50F) to whisk away the excess heat generated by all the bodies and electronics onboard. The reduced air pressure on airline flights can reduce the amount of oxygen in passengers' blood between 6 and 25%, a drop that in hospital would lead many doctors to administer supplementary oxygen. There are some studies, however, that show even relatively mild levels of hypoxia (deficiency in oxygen) can alter our ability to think clearly. At oxygen levels equivalent to altitudes above 12,000ft (3.6km), healthy adults can start to show measurable changes in their memory, their ability to perform calculations and make decisions. This is why the aviation regulations insist that pilots must wear supplementary oxygen if the cabin air pressure is greater than 12,500ft. A study in 2007 showed that after about three hours at the altitudes found in airline cabins, people start to complain about feeling uncomfortable."

Scientists Create World's First 'Molecular Robot' Capable of Building Molecules (scienmag.com) 47

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 (betanews.com) 46

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.

E-Cigarettes With Nicotine Increase Your Risk of Heart Disease, Says Study (theverge.com) 72

An anonymous reader quotes a report from The Verge: Even after puffing on just one electronic cigarette with nicotine, healthy non-smokers were found to have a biological marker known to increase the risk of heart disease in tobacco users, according to a new study. The research, published in Journal of the American Heart Association, shows that nicotine is not harmless, as many people believe. It can affect a smoker's health in more than one way, and not just by triggering addiction. Another study, conducted by Middlekauff that was published earlier this year, showed that people who use e-cigs almost every day have biological markers known to increase the risk of heart disease in tobacco users. These included an increase in adrenaline levels in the heart, which can predispose smokers to bad heart rhythms, heart attacks, and sudden death, as well as increased oxidative stress, an imbalance in the body's ability to defend itself against the damaging action of free radicals. Oxidative stress can lead to changes in blood fats and lead to arteriosclerosis.

That study, however, didn't show what exactly was causing those changes. E-cigarettes can have different flavoring and solvents, as well as nicotine. So to identify the culprit, Middlekauff brought 33 healthy non-smokers and non-vapers into the lab. On three different days, one month apart, the participants were asked to puff on three different kinds of e-cigarettes for 30 minutes: one with nicotine, one without nicotine, and a sham e-cig that was empty. The researchers did blood tests and measured the subjects' heart rhythms, and found that the participants had high levels of adrenaline in their hearts after they smoked the e-cig with nicotine, but not after they puffed on the e-cigarette without nicotine or the empty e-cig.

Democrats Ask FEC To Create New Rules To Keep Foreign Influence Off Social Media Ads (thehill.com) 132

Cristina Marcos reports via The Hill: Democratic lawmakers on Wednesday asked the Federal Election Commission (FEC) to establish new guidelines for online advertising platforms that would prevent foreign spending to influence U.S. elections. The move comes after Facebook provided information to Congress and special counsel Robert Mueller, who is leading the FBI's investigation into Russia's election interference, about Russian ad purchases during the 2016 campaign.

"The recent revelations that foreign nationals with suspected ties to the Russian government sought to influence the 2016 election through social media advertisements are deeply concerning and demand a response," 20 House and Senate Democrats wrote in the letter. "We are fast approaching the 2018 election cycle. As such, it is imperative the Federal Election Commission begin this effort in earnest," they wrote. CNN, which first reported on the Democrats' letter, cited Facebook sources saying they expect Congress may try to require disclaimers on online political ads in the future, similar to political television ads. The Democratic lawmakers suggested that any FEC guidance address how foreign actors can use corporate or nonprofit designations to avoid disclosing political spending; what advertisement platforms can do to prevent foreign campaign activity; and possible changes to disclosure standards for political advertisements.

China Arms Upgraded Tianhe-2A Hybrid Supercomputer (nextplatform.com) 19

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 Customers Can Now Return Things For Free At Kohl's Or Whole Foods (mashable.com) 28

In addition to any of the hundreds of Whole Foods supermarkets across the country, certain Kohl's stores will now accept returns of "eligible items" as part of a retail partnership between the two companies that began earlier this summer. Mashable reports: Starting next month, more than 80 Kohl's locations in the Chicago and Los Angeles area will begin packing and shipping returns back to the online shopping giant's warehouses free of charge. The stores will even have specially designated parking spots for Amazon returns customers. In exchange, Kohl's is hoping that some of the people this program draws into its stores will be tempted to buy something there along the way. One recent UPS survey found that around 70 percent of consumers tend to make new purchases in the course of returning items in stores. The new array of return options will also help Amazon undercut its arch-rival Walmart, which has staked its big push to catch up with Amazon on the idea that its thousands of stores can serve as waypoints for pick-ups, returns, and more convenient delivery.

Computer Science Degrees Aren't Returning On Investment For Coders, Research Finds (theregister.co.uk) 213

According to a new survey, coders with a bachelor's degree in computer science only earn 3,000 British Pounds (BP) more a year than those who don't have one. The survey of 4,700 developers in the UK was conducted by Stack Overflow, a community site frequented by developers for answers to technical questions. The Register reports the findings: This is despite the average degree now costing 9,000 BP a year in tuition fees alone. Average student debt is now more than 50,000 BP, according the Institute of Fiscal Studies. The research found that the median salary of those who did not have higher education was 35,000 BP per year, while those who gained a bachelor's degree earned 38,000 BP and postgraduates took home 42,000 BP. It found that 48 per cent of developers with less than four years of professional experience currently hold a Computer Science-related undergraduate degree, while 49 per cent had completed an online course instead. The research also found that JavaScript developers were most in demand, with almost 27 per cent of jobs advertised on Stack Overflow now requiring this skill, followed by Java (22 per cent), Python (16 per cent), C# (15 per cent) and ReactJS (9 per cent).

More Are Paying To Stream Music, But YouTube Still Holds the Value Gap (theregister.co.uk) 24

An anonymous reader shares a report: With Google's user-generated content loophole firmly in lawmaker's sights, global music trade body IFPI has published new research looking at demand for music streaming. The research confirms YouTube's pre-eminence as the world's de facto jukebox. 46 percent of on-demand music streaming is from Google's video website. 75 percent of internet users use video streaming to hear music. The paid-for picture is bullish: 50 percent of internet users have paid for licensed music in the last six months, in one form or another, of which 53 per are 13- to 15-year-olds. Audio streaming is split between 39 percent who stream for free and 29 percent who pay. [...] So what's the problem? European policy makers have become convinced by the "value gap" argument: compensation doesn't reflect usage. Google finds itself with a unique advantage here, thanks to YouTube's "user-generated content" exception, as we explained last year.

Bill Gates Says He's Sorry About Control-Alt-Delete (qz.com) 224

An anonymous reader quotes a report from Quartz: At the Bloomberg Global Business Forum today, Carlyle Group co-founder and CEO David Rubenstein asked Microsoft founder Bill Gates to account for one of the most baffling questions of the digital era: Why does it take three fingers to lock or log in to a PC, and why did Gates ever think that was a good idea? Grimacing slightly, Gates deflected responsibility for the crtl-alt-delete key command, saying, "clearly, the people involved should have put another key on to make that work." Rubenstein pressed him: does he regret the decision? "You can't go back and change the small things in your life without putting the other things at risk," Gates said. But: "Sure. If I could make one small edit I would make that a single key operation." Gates has made the confession before. In 2013, he blamed IBM for the issue, saying, "The guy who did the IBM keyboard design didn't want to give us our single button."

Amazon Is Reportedly Working On Alexa-Enabled Smart Glasses (techcrunch.com) 31

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 (phoronix.com) 30

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."

Seismologist Explains Mexico's Back-To-Back Earthquakes (theverge.com) 44

An anonymous reader quotes a report from The Verge: The second major earthquake to strike Mexico in less than two weeks has caused catastrophic damage in the country's capital. The magnitude 7.1 temblor started at around 1:15PM -- cracking highways, collapsing buildings, and, so far, killing more than 200 people. Less than two weeks ago on September 7th (local time), a magnitude 8.1 quake struck roughly 400 miles southeast from today's. It's not common to hear of such strong earthquakes happening back-to-back so close to one another, says John Bellini, a geophysicist with the U.S. Geological Survey. "Usually you don't have large ones in the same general region right away," Bellini says. "But in highly [seismically] active regions of the world, it can happen."

Mexico qualifies as highly active. The country sits at the boundary of three pieces of the Earth's crust that fit together like a jigsaw puzzle -- called tectonic plates. Today's quake originated on a fault within the Cocos plate, which is on Mexico's western edge. "Whether or not faults rupture depends on the kind of stress that builds up," Bellini says. The Cocos plate scoots rapidly under the continental crust of the North American plate, which "builds up the stress and strain at a faster rate," Bellini says. "So you're liable to have more frequent earthquakes because of that." Mexico City is especially prone to severe damage because of the ground it sits on -- an ancient lakebed that quivers like jello, Bellini says. When earthquake waves pass through it, it jiggles, magnifying the vibrations. "So the reason that Mexico City seems susceptible to more damage is because of this amplification effect of the lake bed," Bellini says.

Mathematical Formula Predicts Global Mass Extinction Event in 2100 (vice.com) 322

Kate Lunau, writing for Motherboard: A new paper in Science Advances finds that a mass extinction period mirroring ones from our planet's ancient past could be triggered when humanity adds a certain amount of carbon to the oceans, which are home to the majority of all plants and animals on our planet. The paper pegs that amount at 310 gigatons. According to lead author Daniel Rothman of MIT, based on projections from the Intergovernmental Panel on Climate Change, we're on course to hit that number by 2100. After that, we enter "unknown territory." [...] Previous mass extinctions have happened over the course of thousands or millions of years, but the period of change we're in right now has lasted centuries at best, making it hard to compare them. Although plenty of experts say Earth is already experiencing a sixth mass extinction, that remains "a scientific question," Rothman, who is professor of geophysics in the MIT Department of Earth, Atmospheric and Planetary Sciences, told me. Once our planet hits the threshold he identified in this paper, he explained, it will kickstart changes that will "amplify" everything that came before. These same changes, to reiterate, have been associated with all previous mass extinctions on Earth.
