Android 61

DeviceGuru writes Eltechs announced a virtual machine that runs 32-bit x86 Linux applications on ARMv7 hardware. The ExaGear VM implements a virtual x86 Linux container on ARMv7 computers and is claimed to be 4.5 times faster than QEMU, according to Eltechs. The VM is based on binary translation technology and requires ARMv7, which means it should run on mini-PCs and SBCs based on Cortex-A8, A7, A9, and A15 processors — but sadly, it won't run on the ARM11 (ARMv6) SoC found on the Raspberry Pi. It also does not support applications that require kernel modules. It currently requires Ubuntu (v12.04 or higher), but will soon support another, unnamed Linux distro, according to Eltechs, which is now accepting half price pre-orders without payment obligation.

Ask Slashdot: Where Can I Find Good Replacement Batteries?

Power 131

An anonymous reader writes: I have an old phone with a battery that barely works anymore. My current phone's battery is mediocre — I can put up with it, but I've been thinking about getting a new one. My four-year-old ThinkPad holds less of a charge than I'd like, and less than it did when I bought it. In all these cases, the only thing holding me back from buying a new battery is that I'm not sure where to find a good one. Searching for my phone's battery on Amazon (or any major online retailer) yields a dozen results, all fairly cheap. But which are reliable? They all seem to have varying reviews, ranging from "Perfect official factory replacement!" to "Garbage knock-off, worse than the battery I replaced." Part numbers don't seem to help, as the knock-offs replicate those pretty well. I ask you, Slashdot: where can I find a good replacement battery?

A Better Way To Make Mind-Controlled Prosthetic Limbs

the_newsbeagle writes: To make a brain-machine interface, you need a way to capture neurons' electric signals. The most precise and most invasive way uses implants that are stuck in the gray matter. The least precise and least invasive way uses EEG sensors stuck to the scalp. But researchers at Johns Hopkins University say there's a third way that gets the best of both worlds, which is not too invasive and fairly precise. They use ECoG systems, in which a mesh of electrodes is placed under the skull, draped over the surface of the cortex.

They're testing their systems on epilepsy patients, who have these ECoG systems inserted anyway while they're waiting for surgery (the electrodes record the source of their seizures). The researchers are capturing these patients' movement commands from their brains, and using them to control robotic limbs. Someday such a system could be used by amputees to control their prosthetic limbs.

gthuang88 writes: As the marketing hype around "big data" subsides, a recent wave of startups is solving a new class of data-related problems and showing where the field is headed. Niche analytics companies like RStudio, Vast, and FarmLink are trying to provide insights for specific industries such as finance, real estate, and agriculture. Data-wrangling software from startups like Tamr and Trifacta is targeting enterprises looking to find and prep corporate data. And heavily funded startups such as Actifio and DataGravity are trying to make data-storage systems smarter. Together, these efforts highlight where emerging data technologies might actually be used in the business world.

How Does Tesla Build a Supercharger Charging Site?

Transportation 190

cartechboy writes Tesla's Superchargers are the talk of the electric car community. These charging stations can take a Model S battery pack from nearly empty to about 150 miles of range in around 30 minutes. That's crazy fast, and it's nothing short of impressive. But what does it take to actually build a Tesla Supercharger site? Apparently a lot of digging. A massive trench is created to run high-capacity electric cables before the charging stations themselves are even installed. A diagram and photos of the Electric Conduit Construction build out have surfaced on the Internet. The conduits connect the charging stations to a power distribution center, which in turn is connected to a transformer that provides the power for charging cars. It took 11 days to install the six charging stalls in Goodland, Kansas. If you thought it was a quick process to build a Supercharger station, you were clearly wrong.

How Argonne National Lab Will Make Electric Cars Cheaper

ashshy writes Argonne National Lab is leading the charge on next-generation battery research. In an interview with The Motley Fool, Argonne spokesman Jeff Chamberlain explains how new lithium ion chemistries will drive down the cost of electric cars over the next few years. "The advent of lithium ion has truly enabled transportation uses," Chamberlain said. "Because if you remember your freshman chemistry, you think of the periodic table -- lithium is in the upper left-hand corner of the periodic table. Only hydrogen and helium are lighter on an atomic basis."

The project is expected to take two years to complete, and if all goes as planned the printer will automatically insert rebar into the concrete.

Solar Plant Sets Birds On Fire As They Fly Overhead

Elledan writes: Federal investigators in California have requested that BrightSource — owner of thermal solar plants — halt the construction of more (and bigger) plants until their impact on wildlife has been further investigated. "Unlike many other solar plants, the Ivanpah plant does not generate energy using photovoltaic solar panels. Instead, it has more than 300,000 mirrors, each the size of a garage door. Together, they cover 1,416 hectares. Each mirror collects and reflects solar rays, focusing and concentrating solar energy from their entire surfaces upward onto three boiler towers, each looming up to 40 stories high. The solar energy heats the water inside the towers to produce steam, which turns turbines that generate enough electricity for 140,000 homes." The concentrated solar energy chars and incinerates the feathers of passing birds. BrightSource estimates about a thousand bird die this way every year, but an environmental group claims the real number is much higher.

If Fusion Is the Answer, We Need To Do It Quickly

Power 305

Lasrick writes: Yale's Jason Parisi makes a compelling case for fusion power, and explains why fusion is cleaner, safer, and doesn't provide opportunities for nuclear smuggling and proliferation. The only downside will be the transition period, when there are both fission and fusion plants available and the small amount of "booster" elements (tritium and deuterium) found in fusion power could provide would-be proliferators what they need to boost the yield of fission bombs: "The period during which both fission and fusion plants coexist could be dangerous, however. Just a few grams of deuterium and tritium are needed to increase the yield of a fission bomb, in a process known as 'boosting.'" Details about current research into fusion power and an exploration of relative costs make fusion power seem like the answer to a civilization trying to get away from fossil fuels.

Chrome 215

New submitter nrjperera (2669521) submits news of a new laptop from HP that's in Chromebook (or, a few years ago, "netbook") territory, price-wise, but loaded with Windows 8.1 instead. Microsoft has teamed up with HP to make an affordable Windows laptop to beat Google Chromebooks at their own game. German website Mobile Geeks have found some leaked information about this upcoming HP laptop dubbed Stream 14, including its specifications. According to the leaked data sheet the HP Stream 14 laptop will share similar specs to HP's cheap Chromebook. It will be shipped with an AMD A4 Micro processor, 2GB of RAM, 32GB of flash storage and a display with 1,366 x 768 screen resolution. Microsoft will likely offer 100GB of OneDrive cloud storage with the device to balance the limited storage option.

AMD Launches Radeon R7 Series Solid State Drives With OCZ

Data Storage 64

MojoKid (1002251) writes AMD is launching a new family of products today, but unless you follow the rumor mill closely, it's probably not something you'd expect. It's not a new CPU, APU, or GPU. Today, AMD is launching its first line of solid state drives (SSDs), targeted squarely at AMD enthusiasts. AMD is calling the new family of drives, the Radeon R7 Series SSD, similar to its popular mid-range line of graphics cards. The new Radeon R7 Series SSDs feature OCZ and Toshiba technology, but with a proprietary firmware geared towards write performance and high endurance. Open up one of AMD's new SSDs and you'll see OCZ's Indilinx Barefoot 3 M00 controller on board—the same controller used in the OCZ Vector 150, though it is clocked higher in these drives. That controller is paired to A19nm Toshiba MLC (Multi-Level Cell) NAND flash memory and a DDR3-1333MHz DRAM cache. The 120GB and 240GB drives sport 512MB of cache memory, while the 480GB model will be outfitted with 1GB. Interestingly enough, AMD Radeon R7 Series SSDs are some of the all-around, highest-performing SATA SSDs tested to date. IOPS performance is among the best seen in a consumer-class SSD, write throughput and access times are highly-competitive across the board, and the drive offered consistent performance regardless of the data type being transferred. Read performance is also strong, though not quite as stand-out as write performance.

1sockchuck writes In a unique approach to data center design, the new high-performance computing center in Oregon is housed in a geodesic dome. The new facility at the Oregon Health and Science University requires no mechanical air conditioning, using outside air to racks of servers reaching densities of 25kW per cabinet. The design uses an aisle containment system to separate hot and cold air, and can recirculate server exhaust heat to adjust cold aisle temperatures in the winter. It's a very cool integration of many recent advances in data center design, combining elements of the Yahoo Chicken Coop and server silo in Quebec. The school has posted a virtual tour that provides a deep technical dive.

The Cost of Caring For Elderly Nuclear Plants Expected To Rise

samzenpus posted about 3 months ago | from the keeping-it-going dept.

EU 249

mdsolar writes with this story about the rising costs of keeping Europe's nuclear power plants safe and operational. Europe's aging nuclear fleet will undergo more prolonged outages over the next few years, reducing the reliability of power supply and costing plant operators many millions of dollars. Nuclear power provides about a third of the European Union's electricity generation, but the 28-nation bloc's 131 reactors are well past their prime, with an average age of 30 years. And the energy companies, already feeling the pinch from falling energy prices and weak demand, want to extend the life of their plants into the 2020s, to put off the drain of funding new builds. Closing the older nuclear plants is not an option for many EU countries, which are facing an energy capacity crunch as other types of plant are being closed or mothballed because they can't cover their operating costs, or to meet stricter environmental regulation.

Is Storage Necessary For Renewable Energy?

mdsolar writes Physicist and energy expert Amory Lovins, chief scientist at The Rocky Mountain Institute, recently released a video in which he claims that renewable energy can meet all of our energy needs without the need for a fossil fuel or nuclear baseload generation. There's nothing unusual about that — many people have made that claim — but he also suggests that this can be done without a lot of grid-level storage. Instead, Lovins describes a "choreography" between supply and demand, using predictive computer models models to anticipate production and consumption, and intelligent routing to deliver power where it's needed. This "energy dance," combined with advances in energy efficiency, will allow us to meet all of our energy needs without sacrificing reliability.

Delays For SC Nuclear Plant Put Pressure On the Industry

Soulskill posted about 3 months ago | from the i'm-sure-there's-a-duke-nukem-joke-here dept.

Power 142

mdsolar sends this news from the Associated Press: Expensive delays are piling up for the companies building new nuclear power plants, raising fresh questions about whether they can control the construction costs that crippled the industry years ago. The latest announcement came this week from executives at SCANA Corp., which has been warned by its builders the startup of the first of two new reactors in South Carolina could be delayed two years or more. ... That announcement may well foreshadow more delays for a sister project in eastern Georgia, and they have caught the attention of regulators and Wall Street. 'Delays generally cause cost increases, and the question becomes who's going to bear the costs?' said C. Dukes Scott, executive director of the South Carolina Office of Regulatory Staff, a watchdog agency that monitors SCANA Corp.'s spending.

None of this is helpful for the nuclear power industry, which had hoped its newest generation of plants in Georgia and South Carolina would prove it could build without the delays and cost overruns so endemic years ago. When construction slows down, it costs more money to employ the thousands of workers needed to build a nuclear plant. Meanwhile, interest charges add up on the money borrowed to finance construction. A single day of delay in Georgia could cost $2 million, according to an analysis by utility regulators.

Fukushima's Biological Legacy

Japan 116

An anonymous reader sends this report from Eurekalert: Scientists began gathering biological information only a few months after the disastrous 2011 meltdown of the Fukushima power plant in Japan. Results of these studies are now beginning to reveal serious biological effects of the Fukushima radiation on non-human organisms ranging from plants to butterflies to birds. A series of articles summarizing these studies has been published in the Journal of Heredity describing impacts ranging from population declines to genetic damage (abstract 1, abstract 2, abstract 3, abstract 4). Most importantly, these studies supply a baseline for future research on the effects of ionizing radiation exposure to the environment. Common to all of the published studies is the hypothesis that chronic (low-dose) exposure to ionizing radiation results in genetic damage and increased mutation rates in reproductive and non-reproductive cells. Meanwhile, efforts to restart Japan's nuclear power program are dead in the water.

Processors and the Limits of Physics

Hardware 168

An anonymous reader writes: As our CPU cores have packed more and more transistors into increasingly tiny spaces, we've run into problems with power, heat, and diminishing returns. Chip manufacturers have been working around these problems, but at some point, we're going to run into hard physical limits that we can't sidestep. Igor Markov from the University of Michigan has published a paper in Nature (abstract) laying out the limits we'll soon have to face. "Markov focuses on two issues he sees as the largest limits: energy and communication. The power consumption issue comes from the fact that the amount of energy used by existing circuit technology does not shrink in a way that's proportional to their shrinking physical dimensions. The primary result of this issue has been that lots of effort has been put into making sure that parts of the chip get shut down when they're not in use. But at the rate this is happening, the majority of a chip will have to be kept inactive at any given time, creating what Markov terms 'dark silicon.' Power use is proportional to the chip's operating voltage, and transistors simply cannot operate below a 200 milli-Volt level. ... The energy use issue is related to communication, in that most of the physical volume of a chip, and most of its energy consumption, is spent getting different areas to communicate with each other or with the rest of the computer. Here, we really are pushing physical limits. Even if signals in the chip were moving at the speed of light, a chip running above 5GHz wouldn't be able to transmit information from one side of the chip to the other."

Not Just For ThinkPads Anymore: Lenovo Gets OK To Buy IBM Server Line

IBM sold its personal computer line (including the iconic ThinkPad line) to Lenovo back in 2005. Now, Lenovo is poised to acquire IBM's line of X86-based servers, and has garnered the approval of a regulatory body which could have scotched the deal. (The article describes the server line at issue as "low end," but that's in the eye of the beholder.) From the article: The conclusion of the review by the Committee on Foreign Investment in the U.S., or Cfius, is “good news for both IBM and Lenovo, and for our customers and employees,” Armonk, New York-based IBM said yesterday in a statement. While Cfius placed some conditions on the deal, they don’t significantly affect the business, and terms of the transaction didn’t change as result, a person with knowledge of the matter said, without specifying the conditions. The sale drew scrutiny because of disputes between China and the U.S., the world’s two largest economies, over cyberintrusions. By completing the deal, IBM can jettison a less profitable business to focus on growing areas, such as cloud computing and data analytics, while giving Lenovo a bigger piece of the global computing-hardware market. ... Spokesmen for IBM and Lenovo declined to comment on whether the Cfius clearance included any requirements or concessions. Holly Shulman, a spokeswoman for the Treasury Department, which leads Cfius, declined to comment.

I saw it first on the econfuture site by Martin Ford, author of The Lights in the Tunnel. It is being discussed on Reddit, and people there have started mentioning a "basic income" as one possible response. While I like the basic income idea, I also collect other approaches in an essay called Beyond A Jobless Recovery: A heterodox perspective on 21st century economics. Beyond a basic income for the exchange economy, those possible approaches include gift economy, subsistence production, planned economy, and more — including many unpleasant alternatives like expanding prisons or fighting wars as we are currently doing.

Marshall Brain's writings like Robotic Nation and Manna have inspired my own work. I made my own video version of the concept around 2010, as a parable called "The Richest Man in the World: A parable about structural unemployment and a basic income." (I also pulled together a lot of links to robot videos in 2009.) It's great to see more informative videos on this topic. CGP Grey's video is awesome in the way he puts it all together.

Communications 38

An anonymous reader writes Ryan Lackey of CloudFlare and Marc Rogers of Lookout revealed a new OPSEC device at Def Con called PORTAL (Personal Onion Router to Assure Liberty). It "provides always-on Tor routing, as well as 'pluggable' transport for Tor that can hide the service's traffic signature from some deep packet inspection systems." In essence, PORTAL is a travel router that the user simply plugs into their existing device for more than basic Tor protection (counterpoint to PogoPlug Safeplug and Onion Pi). On the down side, you have to download PORTAL from Github and flash it "onto a TP-Link compatible packet router." The guys behind the device acknowledge that not many people may want to (or even know how to) do that, so they're asking everyone to standby because a solution is pending. The project's GitHub page has a README file that lists compatible models, with some caveats: "It is highly recommended to use a modified router. The modified MR11U and WR703N provide a better experience than the stock routers due to the additional RAM. The severe space constraints of the stock router make them very challenging to work with. Due to the lack of usable space, it is necessary to use an external disk to store the Tor packages. The stock router has only a single USB port, and the best option is to use a microSD in a 3G modem." (Note: Lackey is no stranger to helping people secure internet privacy.)

The Skully AR-1 helmet launched on Indiegogo on Aug. 10 and quickly blasted past its $250,000 flexible funding goal and has already surpassed $900,000 in funding. The helmet runs a heavily modified version of Android 4.4, with both screen size and safety in mind, according to Skully's Tow. 'You should not think of it as being Android as seen in a phone; it doesn't run the same skin,' wrote Tow on the Skully forum page. 'You instead should think of it as a variant of Linux, not Android per se. What counts is the device drivers, graphics rendering for our turn by turn directions and vehicle telemetry, etc. More nerdy things like communication over the I2C bus to the image processing module.' Helmets are available starting at $1,399, with shipments due in May 2015.

Solid State Drives Break the 50 Cents Per GiB Barrier, OCZ ARC 100 Launched

MojoKid (1002251) writes Though solid state drives have a long way to go before they break price parity with hard drives (and may never make it, at least with the current technology), the gap continues to close. More recently, SSD manufacturers have been approaching 50 cents per GiB of storage. OCZ Storage Solutions, with the help of their parent company Toshiba's 19nm MLC NAND, just launched their ARC 100 family of drives that are priced at exactly .5 per GiB at launch and it's possible street prices will drift lower down the road. The ARC 100 features the very same OCZ Barefoot 3 M10 controller as the higher-end OCZ Vertex 460, but these new drives feature more affordable Toshiba A19nm (Advanced 19 nanometer) NAND flash memory. The ARC 100 also ships without any sort of accessory bundle, to keep costs down. Performance-wise, OCZ's new ARC 100 240GB solid state drive didn't lead the pack in any particular category, but the drive did offer consistently competitive performance throughout testing. Large sequential transfers, small file transfers at high queue depths, and low access times were the ARC 100's strong suits, as well as its low cost. These new drives are rated at 20GB/day write endurance and carry a 3-year warranty.

Egle Murauskaite of the U.S. National Consortium for the Study of Terrorism and Responses to Terrorism (START) describes why concentrating on this aspect of the smuggling process, long considered less egregious than the actual selling of the material, could really make a difference in keeping radioactive materials off the black market in the first place.

"With the Type-C spec finalized, it now comes down to the USB-IF to actually implement the sockets, plugs, cables, adapters, and devices. The problem is that there are billions of existing USB devices and cables that will need adapters and new cables to work with new Type-C devices. It’s a lot like when Apple released the Lightning connector, but on an even grander scale. Further exacerbating the issue is the fact that China, the EU, and the GSMA have all agreed that new mobile devices use Micro-USB for charging — though it might be as simple as including a Micro-USB-to-Type-C adapter with every new smartphone."

Joshua Lifton says you can learn to type at 225 words per minute with his Stenosaurus, an open source stenography keyboard that has a not-there-yet website with nothing but the words, "Stenography is about to evolve," on it as of this writing. If you've heard of Joshua it's probably because he's part of the team behind Crowd Supply, which claims, "Our projects raise an average of $43,600, over twice as much as Kickstarter." A brave boast, but there's plenty of brainpower behind the company. Joshua, himself. has a PhD from MIT, which according to his company bio means, "he's devoted a significant amount of his time learning how to make things that blink." But the steno machine is his own project, independent of Crowd Supply.

Stenotype machines are usually most visible when court reporters are using them. They've been around since the 1800s, when their output was holes in paper tape. Today's versions are essentially chorded keyboards that act as computer input devices. (Douglas Engelbart famously showed off a chorded keyboard during his 1968 Mother of All Demos.) Today you have The Open Steno Project, and Stenosaurus is a member. And while Joshua's project may not have an actual website quite yet, it has an active blog. And the 225 WPM claim? Totally possible. The world record for English language stenography is 360 WPM. And you thought the Dvorak Keyboard was fast. Hah! (Alternate Video Link)

Errata Prompts Intel To Disable TSX In Haswell, Early Broadwell CPUs

Soulskill posted about 3 months ago | from the somebody-is-getting-fired dept.

Intel 131

Dr. Damage writes: The TSX instructions built into Intel's Haswell CPU cores haven't become widely used by everyday software just yet, but they promise to make certain types of multithreaded applications run much faster than they can today. Some of the savviest software developers are likely building TSX-enabled software right about now. Unfortunately, that work may have to come to a halt, thanks to a bug—or "errata," as Intel prefers to call them—in Haswell's TSX implementation that can cause critical software failures. To work around the problem, Intel will disable TSX via microcode in its current CPUs — and in early Broadwell processors, as well.

Microsoft Research Brings Kinect-Style Depth Perception to Ordinary Cameras

mrspoonsi (2955715) writes "Microsoft has been working on ways to make any regular 2D camera capture depth, meaning it could do some of the same things a Kinect does. As you can see in the video below the team managed to pull this off and we might see this tech all around in the near future. What's really impressive is that this works with many types of cameras. The research team used a smartphone as well as a regular webcam and both managed to achieve some impressive results, the cameras have to be slightly modified but that's only to permit more IR light to hit the sensor." The video is impressive, but note that so are several of the other projects that Microsoft has created for this year's SIGGRAPH, in particular one that makes first-person sports-cam footage more watchable.

NVIDIAs 64-bit Tegra K1: The Ghost of Transmeta Rides Again, Out of Order

Transmeta 125

MojoKid (1002251) writes Ever since Nvidia unveiled its 64-bit Project Denver CPU at CES last year, there's been discussion over what the core might be and what kind of performance it would offer. Visibly, the chip is huge, more than 2x the size of the Cortex-A15 that powers the 32-bit version of Tegra K1. Now we know a bit more about the core, and it's like nothing you'd expect. It is, however, somewhat similar to the designs we've seen in the past from the vanished CPU manufacturer Transmeta. When it designed Project Denver, Nvidia chose to step away from the out-of-order execution engine that typifies virtually all high-end ARM and x86 processors. In an OoOE design, the CPU itself is responsible for deciding which code should be executed at any given cycle. OoOE chips tend to be much faster than their in-order counterparts, but the additional silicon burns power and takes up die area. What Nvidia has developed is an in-order architecture that relies on a dynamic optimization program (running on one of the two CPUs) to calculate and optimize the most efficient way to execute code. This data is then stored inside a special 128MB buffer of main memory. The advantage of decoding and storing the most optimized execution method is that the chip doesn't have to decode the data again; it can simply grab that information from memory. Furthermore, this kind of approach may pay dividends on tablets, where users tend to use a small subset of applications. Once Denver sees you run Facebook or Candy Crush a few times, it's got the code optimized and waiting. There's no need to keep decoding it for execution over and over.

Gas Cooled Reactors Shut Down In UK

United Kingdom 120

mdsolar writes EDF Energy, the British subsidiary of the French state-controlled utility, said on Monday that it was shutting down three nuclear reactors and that a reactor with a fault that has been shut down since June would remain so. The facilities, which are being investigated as a precaution, generate nearly a quarter of nuclear capacity in Britain. The British Office for Nuclear Regulation said that there had been no release of radioactive material and no injuries. Industry experts did not anticipate much effect on electricity supplies or prices in the short term. EDF said that over the next few days it would idle a second reactor at the facility, Heysham 1, in northwest England. The company said it would also shut down two other reactors of similar design at Hartlepool in northeast England to investigate whether they had the same flaws.

Intel's 14-nm Broadwell CPU Primed For Slim Tablets

Intel 96

crookedvulture writes Intel's next-gen Broadwell processor has entered production, and we now know a lot more about what it entails. The chip is built using 14-nm process technology, enabling it to squeeze into half the power envelope and half the physical footprint of last year's Haswell processors. Even the thickness of the CPU package has been reduced to better fit inside slim tablets. There are new power-saving measures, too, including a duty cycle control mechanism that shuts down sections of the chip during some clock cycles. The onboard GPU has also been upgraded with more functional units and hardware-assisted H.265 decoding for 4K video. Intel expects the initial Broadwell variant, otherwise known as the Core M, to slip into tablets as thin as the iPad Air. We can expect to see the first systems on shelves in time for the holidays.

Microsoft Surface Drowning?

Microsoft 337

hcs_$reboot (1536101) writes Again, not much good news for the MS Surface. Computerworld reports a Microsoft's losses on the tablet device at $US1.7 billion so far. But, still, Microsoft is serene: "It's been exciting to see the response to the Surface Pro 3 from individuals and businesses alike. In fact, Surface Pro 3 sales are already outpacing prior versions of Surface Pro. The Surface business generated more than $2B in revenue for the fiscal year 2014 and $409 million in revenue during Q4 FY14 alone, the latter of which included just ten days of Intel Core i5 Surface Pro 3 sales in Canada and the US." Should Microsoft pull the plug on the tablet? Or maybe it's just a matter of users getting used to the Surface? Even if they're losing money on the Pro 3, Microsoft has seemingly little to be ashamed of when it comes to reviews of the hardware.

Point-and-Shoot: TrackingPoint's New Linux-Controlled AR-15s

timothy posted about 3 months ago | from the future-is-now dept.

Linux Business 219

Ars Technica takes a look at the next generation of TrackingPoint's automatically aimed rifles (not "automatic" in the usual sense), and visited the shooting range where they're tested out. Like the company's previous generation of gun (still in production, and increasingly being sold to government buyers), TrackingPoint's offerings integrate a Linux computer that makes acquiring and tracking a target far easier and more accurate than it would otherwise be. Unlike the older models, though, this year TrackingPoint is concentrating on AR-15s, rather than longer, heavier bolt-action rifles. A slice: The signature "Tag-Track-Xact" system has gained additional functionality on the AR models, too. With the bolt-action guns, there was only one way to put a round onto a target: first, you sighted in on the thing you wanted to hit and depressed the red tagging button just above the trigger. A red pip would appear in the scope’s crosshairs, and you’d place the pip onto the target and release the button. The scope’s rangefinding laser would then illuminate the target to measure its distance, and the image processor would fix on the object; if you moved, or if the target moved, the red pip would remain atop the target. Then, to fire, you squeezed the trigger and lined the crosshairs up with the target’s pip. When the two coincided, the weapon fired. This method works fine for a bolt-action rifle where every round has to be manually chambered, but it’s less than ideal for a carbine, which one might want to fire off-hand (i.e., standing up and aiming) or from the hip. With this in mind, the AR PGFs have a new "free fire mode," in which you can tag a target once and then shoot at it as many times as you want by pulling the trigger directly, with all the shots using the ballistic data from the first shot’s tag. That means, says writer Lee Hutchinson, a rifle "with essentially 100 percent accuracy at 250 yards."

NVIDIA Tegra K1: First Mobile Chip With Hardware-Accelerated OpenCL

timothy posted about 3 months ago | from the bragging-rights dept.

Graphics 52

New submitter shervinemami writes (starting with a pretty big disclaimer: "I'm an Engineer at NVIDIA.") The latest CompuBench GPU benchmarks show NVIDIA's Tegra K1 running whole OpenCL algorithms around 5x faster than any other mobile device, and individual instructions around 20x faster! This huge jump is because mobile companies have been saying they support OpenCL on mobile devices since early 2013, but what they don't mention is that they only have software API support, not hardware-accelerated OpenCL running faster on their GPUs than CPUs. Now that NVIDIA's Tegra-K1 chip has started shipping in devices and thus is available for full benchmarking, it is clearly the only mobile chip that actually gives you proper hardware-accelerated OpenCL (and CUDA of course!). The K1 is also what's in Google's Project Tango 3-D mapping tablet.

Chicago Mayor Praises Google For Buying Kids Microsoft Surfaces

theodp (442580) writes "Google earned kudos from Chicago Mayor Rahm Emanuel this week for teaming up with Staples to fund the projects of 367 of the city's 22,519 public school teachers on "begfunding" site DonorsChoose.org. "Everything that you asked for...every project that the teachers put on to help their students learn, exceed and excel here in the city of Chicago, you now have fully funded," Mayor Emanuel said. "Chicago's hardworking public school teachers are doing all that they can-and more-to support their students, but they need more help," said Rob Biederman, head of Chicago Public Affairs at Google. "We jumped at the chance to join with DonorsChoose.org and Staples to make Chicago's local classroom wishes come true." So what kind of dreams did Google make possible? Ironically, a look at Google Chicago's Giving Page shows that the biggest project funded by Google was to outfit a classroom with 32 Microsoft Surface RT tablets for $12,531, or about 6.5% of the $190,091 Google award. Other big ticket projects funded by Google included $5,931 for a personal home biodiesel kit and $5,552 for a marimba (in the middle of the spectrum was $748 for "Mindfulness Education"). In addition to similar "flash-funding" projects in Atlanta (paper towels!) and the Bay Area, Google and DonorsChoose have also teamed up this year to reward teachers with $400,000 for recruiting girls to learn to code (part of Google's $50 million Made With Code initiative) and an unknown amount for AP STEM teachers who passed Google muster (part of Google's $5 million AP STEM Access grant)."

Enthusiast Opts For $2200 Laser Eye Surgery To Enhance Oculus Rift Experience

Input Devices 109

An anonymous reader writes After 30 years of wearing glasses, one man says that the Oculus Rift virtual reality headset has prompted him to get laser eye surgery. With farsightedness and astigmatism, he says, "Never thought much about the laser surgery until the Rift, that's for sure." He has an appointment to get the $2200 surgery on the 13th of this month. "For me it is clear, my eyeglasses are like an obstacle for optimal VR experience," he said. He hopes the surgery will remove his need for glasses, which can be uncomfortable inside of the Rift, if they fit at all, and cause several issues such as scratched lenses and lower field of view. Oculus plans to make the consumer version of the Oculus Rift (aka CV1) more friendly to glasses wearers, "...we have a lot of great ideas for supporting glasses in the consumer version [of the Rift] (especially since a huge portion of the Oculus team wears glasses everyday!)" they noted in their Kickstarter.

Add a TV Tuner To Your Xbox (In Europe)

jfruh (300774) writes "The Xbox one isn't just a game console: it's also a nifty media set-top box, and it interacts very well with your TV service — as long as you have cable. Cord-cutters will soon be able to attach their Xbox to an antenna — but only in Europe." The peripheral that Microsoft will soon release allows you to integrate over-the-air content into the Xbox One system. From the images Microsoft released it looks like the tuner is a small box with a port for an antenna cable on one end, and the USB cable on the other. Unfortunately for my readers in North America, as of now, the Xbox One Digital TV Tuner is only scheduled to release in Europe. Microsoft says it supports DVB-T, DVB-T2 and DVB-C television channels, which I hope means something to my European readers; Wikipedia tells me these are European over-the-air cable standards. The TV Tuner will be available in late October for 24.99 in the UK, and for €29.99 in France, Italy, Germany and Spain.
