MojoKid writes "The power efficiency of NVIDA's Maxwell architecture make it ideal for mobile applications, so today's announcement by NVIDIA of a new top-to-bottom line-up of mobile GPUs—most of them featuring the Maxwell architecture—should come as no surprise. Though a couple of Kepler and even Fermi-based GPUs still exist in NVIDIA's new line-up, the heart of the product stack leverages Maxwell. The entry-level parts in the GeForce 800M series consist of the GeForce GT 820M, 830M, and 840M. The 820M is a Fermi-based GPU, but the 830M and 840M are new chips that leverage Maxwell. The meat of the GeForce GTX 800M series consist of Kepler-based GPUs, though Maxwell is employed in the more mainstream parts. NVIDIA is claiming the GeForce GTX 880M will be fastest mobile GPU available, but the entire GTX line-up will offer significantly higher performance then any integrated graphics solution. The GeForce GTX 860M and 850M are essentially identical to the desktop GeForce GTX 750 Ti, save for different frequencies and memory configurations. There are a number of notebooks featuring NVIDIA's GeForce 800M series GPUs coming down the pipeline from companies like Alienware, Asus, Gigabyte, Lenovo, MSI and Razer, though others are sure the follow suit. Some of the machines will be available immediately."

cartechboy writes "What's $50 billion among friends, right? At least Felix Kramer and Gil Friend are thinking big, so there is that. The pair have published an somewhat audacious proposal to spend $50 billion dollars to buy up and then shut down every single private and public coal company operating in the United States. The scientific benefits: eliminating acid rain, airborne emissions, etc). The shutdown proposal includes the costs of retraining for the approximately 87,000 coal-industry workers who would lose their jobs over the proposed 10-year phaseout of coal. Since Kramer and Friend don't have $50 billion, they suggest the concept could be funded as a public service and if governments can't do it maybe some rich guys can — and the names Gates, Buffett and Bloomberg come up. Any takers?"

Sean0michael writes "Recently I had a friend lose their entire electronic collection of music and movies by erasing a RAID array on their home server. He had 20TB of data on his rack at home that had survived a dozen hard drive failures over the years. But he didn't have a good way to backup that much data, so he never took one. Now he wishes he had.

Asking around among our tech-savvy friends though, no one has a good answer to the question, 'how would you backup 20TB of data?'. It's not like you could just plug in an external drive, and using any cloud service would be terribly expensive. Blu-Ray discs can hold a lot of data, but that's a lot of time (and money) spent burning discs that you likely will never need. Tape drives are another possibility, but are they right for this kind of problem? I don' t know. There might be something else out there, but I still have no feasible solution.

So I ask fellow slashdotters: for a home user, how do you backup 20TB of Data?" Even Amazon Glacier is pretty pricey for that much data.

First time accepted submitter evidencebase writes "How can an airliner simply disappear, leaving no clues? And why do we have to wait until the black boxes are found to learn what happened to Flight MH370? As this article explains, there's no good reason that flight data needs to go down with the plane, because the technology to stream it to ground, from the moment things start to go wrong, is already on the market. It can be fitted to a commercial airliner for less than $100,000. But the industry has decided that it's not worth the expense. Tell that the the families of passengers on Flight MH370."

minty3 tipped us to news that UW researchers have built the thinnest LEDs yet: a mere three atoms thick. Quoting El Reg: "Team leader Xiaodong Xu, a UW assistant professor in physics and materials science and engineering, and his graduate student Ross, have published the technique in the latest issue of Nature Nanotechnology. They report that the LEDs are small and powerful enough to be used in optical chips that use light instead of electricity to shuttle signals and data through a processor, or they could be stacked to make new thin and flexible displays."

KentuckyFC writes "One of the more ambitious projects at the South Pole is the Askaryan Radio Array, a set of radio antennas under the ice that will listen for the tell tale signals of high energy neutrinos passing by. This array will eventually be over a thousand times bigger than the current largest neutrino detector: Icecube, which monitors a cubic kilometer of ice next door to the planned new observatory. But there's a problem. How do you supply 24/7 power to dozens of detectors spread over such a vast area in the middle of the Antarctic? The answer is renewable energy power stations that exploit the sun during the summer and the wind all year round. The first of these stations is now up and running at the South Pole and producing power. It is also helping to uncover and iron out the various problems that these stations are likely to encounter. For example; where to put the batteries needed to supply continuous power when all else fails. The team's current approach is to bury the battery to protect it from temperature extremes. That works well but makes maintenance so difficult that scaling this approach to dozens of power stations doesn't seem feasible. That's a problem for the future but for the moment, green power has finally come to the white continent."

theodp writes "Android is free and open," reiterated Google Android Chief Andy Rubin in 2010 as Microsoft launched Windows Phone 7. Rubin added, 'Competition is good for the consumer and if somebody has an idea for a feature or a piece of functionality in their platform and Android doesn't do it, great. I think it's good to have the benefit of choice, but in the end I don't think the world needs another platform.' But now, CNET and Digitimes report that Google is holding up the Asus Transformer Book Duet TD300 (specs), a laptop-tablet hybrid that can instantly switch between Android and Windows 8.1. A source familiar with the Asus Duet told CNET that Google is the one that has not favored the idea, while Microsoft has not, to date, been actively opposed to the idea. 'If true,' reports Apple Insider, 'it may not be the first time Google has helped to quash such a product.' South Korean electronics giant Samsung quietly canceled plans for its hybrid Ativ Q tablet last year, and Digitimes notes that Asus may not be the only company to bow to Google's wishes."

Movie robots often look like (and are portrayed by) people in bulky, bipedal suits. Why aren't more robots built along these lines? It's not just the problem of balance. Reader concertina226 writes "'Building a robot that has legs and walks around is a very expensive proposition. Mother Nature has created many wonderful things but one thing we do have that nature doesn't is the wheel, a continuous rotating joint, and tracks, so we need to make use of inventions to make things simpler,' [iRobot CEO Colin] Angle tells IBTimes UK. 'The reason it has taken so long for the robotics industry to move forward is because people keep trying to make something that is cool but difficult to achieve, rather than trying to find solutions to actual human problems. Technology can be extremely expensive if you don't focus.'" [Beware the autoplaying video.]

So is a ruggedized 10.1" device, which appears to be Amplify's answer to earlier fragility problems, the future of high-tech education? Or is go-big-or-go-home with a 27" touch screen the way to go, perhaps in some kind of next-gen-flip-top-school-desk? Or — cost be damned — are separate classroom and home devices what are really needed?"

Hallie Siegel writes "Robotics expert Alan Winfield offers a sobering counterpoint to Ray Kurzweil's recent claim that 2029 will be the year that robots will surpass humans. From the article: 'It’s not just that building robots as smart as humans is a very hard problem. We have only recently started to understand how hard it is well enough to know that whole new theories ... will be needed, as well as new engineering paradigms. Even if we had solved these problems and a present day Noonian Soong had already built a robot with the potential for human equivalent intelligence – it still might not have enough time to develop adult-equivalent intelligence by 2029'"

An anonymous reader writes "An upcoming VR game for the Oculus Rift aims to let players 'be a Hollywood Hacker.' Listing inspirations from 'Johnny Mnemonic, Hackers, The Lawnmower Man, and the TRON films,' Polygon claims that the game 'does an amazing job at exploring those hacking tropes and often silly visuals to give the player a sense of control and power. This is "real life" hacking as filtered through a Michael Bay fever dream.'"

Hugh Pickens DOT Com writes "Bloomberg reports that the oil industry is pressuring President Barack Obama to end the 41-year-old ban on most crude exports but British Petroleum (BP) isn't waiting for a decision. The British oil giant has signed on to take at least 80 percent of the capacity of a new $360 million mini-refinery in Houston that will process crude just enough to escape restrictions on sales outside the country. 'It's a relatively inexpensive way around the export prohibition,' says Judith Dwarkin 'You can lightly ruffle the hydrocarbons and they are considered processed and then they aren't subject to the ban.' Amid a flood of new US oil, the demand for simple, one-step plants capable of transforming raw crude into exportable products such as propane is feeding a construction boom along the Gulf Coast. The first such mini-refinery, built for 1/10 the cost of a complex, full-scale refinery, is scheduled to open the first phase of its 100,000 barrel-a-day crude processing plant in July, The mini-refineries take advantage of the law that allows products refined from oil to be sold overseas, though not the raw crude itself. 'The international buyers of these products will likely need to refine them further, so this is basically a veiled form of condensate exports,' says Leo Mariani."

An anonymous reader writes "In a Q&A session on Reddit last night with Valve's Gabe Newell, the founder confirmed that the company is in the process of getting the highly anticipated Source 2 game engine 'working well with VR.' Valve's Alex Vlachos, Senior Graphics Programmer, is apparently leading the charge. Still no word on when the engine may ship. Valve, who is openly collaborating with Oculus VR, demonstrated a VR headset prototype in January at Steam Dev Days. The company also launched a beta version of SteamVR which offers Steam's 'Big Picture' mode in a format compatible with the Oculus Rift VR headset. A developer who got to experiment with Valve's VR prototype says it's very impressive, even more so than the original Oculus VR dev kit."

wjcofkc writes "The decline of RadioShack has been painful to watch, and now CNN Money reports that they will be closing 1,100 of their stores, totaling 20% of their brick and mortar presence. RadioShack has also publicly admitted its current stores are out of date and in need of a massive overhaul. But the number-one culprit has been a continuous slide in sales down a steep slope in the area of mobile device sales. A few years ago, in a bid to expand its customer base, RadioShack made a bid to return to its roots as a hobbyist electronic components retailer. Apparently the extra traffic hasn't been enough to make up for their failings. The article mentions that some of their stiffest competition is coming from online retailers. The big question is, in order to ensure their survival, would RadioShack be better off continuing to phase out their brick and mortar presence while making substantial efforts to expand as an exclusively online retailer?"

First time accepted submitter Defenestrar writes "I've recently taken a job at a large state university where I manage the laboratories for a couple of departments. We have a good system to pro-rate costs for shared use of big ticket items, but don't have anything in place for small to medium expense pieces which don't require software control (i.e. AD user authentication logs). It is much more efficient to designate a common room for things like water purifiers and centrifuges, but log books have a history of poor compliance. Also, abuse or neglect of communal property has been an issue in the past (similar to the tragedy of the commons).

Do any of you know of good automatic systems to record user/group equipment usage which would allow for easy data processing down the line (i.e. I don't want to go through webcam archives). Systems which promote accountability and care are a bonus, but for safety reasons we don't want the room's door locked (i.e. no pin/badged access). Most of these systems also require continuous power — so electrical interlocks are not a good option either.

I call on you, my fellow Slashdotters, to do your best and get quickly sidetracked while still including the occasional gem in the comments."

MTorrice writes "Lithium-sulfur batteries promise to store four to five times as much energy as today's best lithium-ion batteries. But their short lifetimes have stood in the way of their commercialization. Now researchers demonstrate that a sulfur-based polymer could be the solution for lightweight, inexpensive batteries that store large amounts of energy. Battery electrodes made from the material have one of the highest energy-storage capacities ever reported" Litihium Ion batteries should maintain capacity for about 1000 cycles, whereas Lithium-sulfur batteries traditionally went kaput after about 100. But it looks like they are getting pretty close to something feasible, from the article: "The best performing copolymer consisted of 90% sulfur by mass. Batteries using this copolymer had an initial storage capacity of 1,225 mAh per gram of material. After 100 charge-discharge cycles, the capacity dropped to 1,005 mAh/g, and after 500 cycles it fell to about 635 mAh/g. In comparison, a lithium-ion battery typically starts out with a storage capacity of 200 mAh/g but maintains it for the life of the battery, Pyun says."

An anonymous reader sends this news from the University of Washington: "[C]omputer scientists have built a low-cost gesture recognition system that runs without batteries and lets users control their electronic devices hidden from sight with simple hand movements. The prototype, called 'AllSee,' uses existing TV signals as both a power source and the means for detecting a user's gesture command (PDF). 'This is the first gesture recognition system that can be implemented for less than a dollar and doesn't require a battery,' said Shyam Gollakota, a UW assistant professor of computer science and engineering. 'You can leverage TV signals both as a source of power and as a source of gesture recognition.' The researchers built a small sensor that can be placed on an electronic device such as a smartphone. The sensor uses an ultra-low-power receiver to extract and classify gesture information from wireless transmissions around us. When a person gestures with the hand, it changes the amplitude of the wireless signals in the air. The AllSee sensors then recognize unique amplitude changes created by specific gestures."
