The code is to be LGPL licensed. The reported reasoning for making Wayland support Android GPU drivers was difficulty in ODM vendors not wishing to offer driver support for platforms aside from Android."

bdking writes "Google says it plans to ship its Google Glass Explorer Edition by the end of April to developers and consumers who paid $1,500 to test the computer-enabled eyewear, with vague plans for a general release (at a lower price) by year's end. But what will you really be able to do with Google Glass, beyond having information presented before your eyes? Even investors who are set to spend millions funding apps development for Google Glass have no clue. Is Google Glass being overhyped as a 'transformational' device?" I bet every real estate agent in the world would like one of these hooked up to a database of houses for sale, so they could instantly scan all the relevant information.
hypnosec writes "The open-source Radeon Gallium3D OpenCL stack has been modified to support Bitcoin mining through the use of mining application 'bfgminer.' To mine Bitcoins using the open source GPU driver, one must use Tom Stellard's non-stock branches of Mesa, LLVM and libclc OpenCL library. Further, bfgminer must be patched as well. Once the patches are applied and modified code of the stack is used, users will be able to mine Bitcoins using the Radeon HD 5000 and Radeon HD 6000 graphics cards; however the cards have to be pre-HD6900 Cayman in case of the HD 6000 series."

MojoKid writes "Intel recently revealed a number of details regarding future Atom and Xeon processors and proposed server rack-level enhancements to improve efficiency and ease upgrades. The company will soon refresh its Xeon and Atom processor lines with new products manufactured using Intel's 22nm process node, which offer improved performance per watt characteristics and expanded feature sets. In total, Intel revealed details of three new low-power, Atom-branded SoCs for the data center, all coming in 2013. Intel is also updating the Xeon E3, E5, and E7 product lines. The Atom processor family will see new SoCs based on designs codenamed Briarwood, Avoton, and Rangeley, while the more powerful Xeons will be updated with Haswell, Ivy Bridge EP, and Ivy Bridge EX-based designs. Xeon E3s will leverage the increased graphics performance of Haswell to improve performance in multimedia-related workloads, like HD video transcodes. OHaswell-based Xeon E3 processors will also offer improved performance per watt over existing Sandy and Ivy Bridge-based designs and Intel will offer Xeon E3 processors with TDPs as low as 13 watts, approximately 25% lower than the prior generation."

concealment sends this quote from the NY Times: "Today’s chips are made on large wafers that hold hundreds of fingernail-sized dies, each with the same electronic circuit. The wafers are cut into individual dies and packaged separately, only to be reassembled on printed circuit boards, which may each hold dozens or hundreds of chips. PARC researchers have a very different model in mind. ... they have designed a laser-printer-like machine that will precisely place tens or even hundreds of thousands of chiplets, each no larger than a grain of sand, on a surface in exactly the right location and in the right orientation. The chiplets can be both microprocessors and computer memory as well as the other circuits needed to create complete computers. They can also be analog devices known as microelectromechanical systems, or MEMS, that perform tasks like sensing heat, pressure or motion. The new manufacturing system the PARC researchers envision could be used to build custom computers one at a time, or as part of a 3-D printing system that makes smart objects with computing woven right into them."
angry tapir writes "New research (PDF) from an Australian university argues that increased carbon emissions from powering data centers aren't the biggest environmental threat from the growth of cloud computing. Instead, the problem is the Wi-Fi and cellular networks increasingly used to access cloud services. By 2015, the energy used to run data centers will be a 'drop in the ocean' compared to the energy used to power wireless access to services. By 2015 the energy consumption associated with 'wireless cloud' will reach 43 terawatt-hours, compared to 9.2 terawatt-hours in 2012 (an increase in carbon footprint from 6 megatons of CO_2 in 2012, up to 30 megatons of CO_2 in 2015). Data centers will comprise only 9 per cent on this increased energy consumption, compared to up to 90 per cent for wireless access."

Ars Technica takes a close look at the crowd-funded Pebble smartwatch. The reviewer had to put up with repeated delays in production as a Kickstarter backer, but seems happy with the watch and optimistic about the future of third-party apps; an SDK is due later this month. "It currently ships with three default watch faces, as well as 12 others that you can load onto the watch with the companion app (free on iOS and Android). By far my favorite custom watch face is 'Fuzzy Time,' which rounds the current time to the nearest 5-minute interval and translates that number to what you might say if your friend asked you the time. While seemingly trivial, I love this rough approximation of time. Rarely do I need to know that it's 5:13:23pm, but seeing that it's 'quarter after five' is awesome."

I would like to scan everything, and only retain the papers for things that don't require the original copies. I'd archive the scans in my heavily backed up NAS. What free and/or open source software is out there that can handle this task of document management? Being able to scan to PDF and associate a date and series of labels to a document would be great, as well as some other metadata such as bill amount. My target OS is OS X, but Linux and Windows would be OK."
hypnosec writes "Developer units of Android based gaming console on-a-stick GameStick have already been shipped but, the units meant for early Kickstarter backers have been delayed by two months and will now ship by late June, PlayJam has revealed. The reason, according to PlayJam, is that the consoles would require stronger tooling as compared to silicon based moulds of the dev consoles, which would be finished sometime by June 10. Further, because of the sheer increase in the number of units, PlayJam has said that it won't be able to afford the air freight and will be going for sea freight instead, which will delay the shipments to June."

Trailrunner7 writes "Source code and a private signing key for firmware manufactured by a popular PC hardware maker American Megatrends Inc. (AMI) have been found on an open FTP server hosted in Taiwan. Researcher Brandan Wilson found the company's data hosted on an unnamed vendor's FTP server. Among the vendor's internal emails, system images, high-resolution PCB images and private Excel spreadsheets was the source code for different versions of AMI firmware, code that was current as of February 2012, along with the private signing key for the Ivy Bridge firmware architecture. AMI builds the AMIBIOS BIOS firmware based on the UEFI specification for PC and server motherboards built by AMI and other manufacturers. The company started out as a motherboard maker, and also built storage controllers and remote management cards found in many Dell and HP computers. 'The worst case is the creation of a persistent, Trojanized update that would allow remote access to the system at the lowest possible level,' researcher Adam Caudill said. 'Another possibility would be the creation of an update that would render the system unbootable, requiring replacement of the mainboard.'"

Specifically, they've hit on a way to derive large amounts of hydrogen from any plant source. The method uses renewable natural resources, releases almost no greenhouse gasses, and needs no costly or heavy metals. The key is using xylose, the most abundant simple plant sugar, to produce a large quantity of hydrogen that previously was attainable only in theory."
alphadogg writes "A mobile app under development can filter phone calls and reroute them directly to voicemail by reading brain waves, cutting the need for users to press buttons on the smartphone screen. The app, called Good Times, is the brainchild of Ruggero Scorcioni, CEO and founder of Brainyno, who presented the technology at the AT&T Innovation Showcase in New York, where some of the company's top research projects were highlighted. The app analyzes brainwaves as a phone call comes in, and depending on a person's mental state, reroutes a call. Information about brain waves is collected by a headset and sent to the smartphone via a Bluetooth connection, after which the app uses algorithms to analyze the status of a brain." Of course, the user has to be wearing a headset to detect the brainwaves. The software's creator hopes such detection can someday be integrated into devices like Google Glass.

Lucas123 writes "Both Viking and Micron plan to ship cards that combine DRAM and NAND flash on a standard DDR3 DIMM. The cards will have twice as much NAND flash as volatile memory. For example, the non-volatile DIMMs will come in capacities ranging from 4GB of DRAM to 16GB and 8GB of flash to 32GB of flash. Micron also sees its NVDIMM card being used as a storage tier, as cache for RAID systems, system check pointing, full system persistence, data logging, de-duplication and fast access to metadata. Without providing specifics, Viking said the NVDIMM cards will cost roughly a few hundred dollars each, more than a standard DDR3 DIMM module but still inexpensive enough for server and storage admins to consider for boosting application performance."

Last time the app was in the news, Apple was stopping Microsoft from pushing out an update in the App Store because the company doesn't pay a 30 percent cut of the subscription revenue it generates. Now we've learned how Microsoft managed to update its iOS app today. 'We worked with Apple to create a solution that benefited our mutual customers,' a Microsoft spokesperson told TNW. 'The SkyDrive app for iOS is slightly different than other SkyDrive apps in that people interested in buying additional storage will do so via the web versus in the app.' Does this set a precedent for an iOS version of Microsoft Office?"
crookedvulture writes "Seagate announced its third-generation hybrid drives last month, revealing a full family of notebook and desktop drives that combine mechanical platters with solid-state storage. These so-called SSHDs are Seagate's first to be capable of caching write requests in addition to reads, and the mobile variants are already selling online. Unfortunately, a closer look at the Laptop Thin SSHD reveals some problems with Seagate's new design. While the integrated flash cache reduces OS and application load times by 30-45%, overall performance appears to be held back by its 5,400-RPM mechanical component. Seagate's last-gen Momentus XT hybrid spins its platters at 7,200-RPM, and it's faster than the new SSHD in a wide range of tests. The upcoming desktop SSHDs will also have 7,200-RPM spindle speeds, so they may prove more appealing than the mobile models."

dcblogs writes "PC manufacturers may try to corral Chromebook, much like Netbooks, by setting frustratingly low hardware expectations. The systems being released from HP, Acer, Lenovo and Samsung are being built around retro Celeron processors and mostly 2 GB of RAM. By doing so, they are targeting schools and semi-impulse buyers and may be discouraging corporate buyers from considering the system. Google's Pixel is the counter-force, but at a price of $1,299 for the Wi-Fi system, reviewers, while gushing about hardware, believe it's too much, too soon. The Chromebook is a threat to everything, especially PC makers, as its apps improve. Compare Tweetdeck's HTML5 version with its native app. Can you tell the difference? It might be a year or two before Adobe delivers Web-only versions of its products, but if it doesn't it will be surrendering larger portions of its mindshare to users of Pixlr, Pixel Mixer, PicMonkey and many other interesting and increasingly capable tools."
KindMind writes "To probably no one's surprise, wiping a smartphone by standard methods doesn't get all the data erased. From an article at Wired: 'Problem is, even if you do everything right, there can still be lots of personal data left behind. Simply restoring a phone to its factory settings won't completely clear it of data. Even if you use the built-in tools to wipe it, when you go to sell your phone on Craigslist you may be selling all sorts of things along with it that are far more valuable — your name, birth date, Social Security number and home address, for example. ... [On a wiped iPhone 3G, mobile forensics specialist Lee Reiber] found a large amount of deleted personal data that he recovered because it had not been overwritten. He was able to find hundreds of phone numbers from a contacts database. Worse, he found a list of nearly every Wi-Fi and cellular access point the phone had ever come across — 68,390 Wi-Fi points and 61,202 cell sites. (This was the same location data tracking that landed Apple in a privacy flap a few years ago, and caused it to change its collection methods.) Even if the phone had never connected to any of the Wi-Fi access points, iOS was still logging them, and Reiber was able to grab them and piece together a trail of where the phone had been turned on.'"

The result is a DRAM chip that has an aggregate bandwidth of 160GB/s, 15 times more throughput as standard DRAMs, while also reducing power by 70%. 'Basically, the beauty of it is that it gets rid of all the issues that were keeping DDR3 and DDR4 from going as fast as they could,' said Jim Handy, director of research firm Objective Analysis. The first versions of the Hybrid Memory Cube, due out in the second half of 2013, will deliver 2GB and 4GB of memory."
MTorrice writes "NASA researchers have compared nuclear power to fossil fuel energy sources in terms of greenhouse gas emissions and air pollution-related deaths. Using nuclear power in place of coal and gas power has prevented some 1.8 million deaths globally over the past four decades and could save millions of more lives in coming decades, concludes their study. The pair also found that nuclear energy prevents emissions of huge quantities of greenhouse gases. These estimates help make the case that policymakers should continue to rely on and expand nuclear power in place of fossil fuels to mitigate climate change, the authors say."

With each new eyebrow-raising court judgment and federal fine levied against Google, he adds, 'it becomes ever more clear that this is a company hell-bent on innovating first and asking questions later, if ever. And its vision, shared with other California technology companies, is of corporate America redefining societal privacy norms in the service of advertising companies and their clients.'

MojoKid writes "Every year, AMD and NVIDIA re-brand their GPU product lines, regardless of whether the underlying hardware has changed. This annual maneuver is a sop to OEMs, who like yearly refreshes and higher numbers. The big introduction NVIDIA is making this year is what it calls GPU Boost 2.0. When NVIDIA launched the GTX Titan in February, it discussed a new iteration of GPU Boost technology that measured GPU temperature rather than estimating TDP. This new approach gave NVIDIA finer-grained control over clock speeds and thermal thresholds, thereby allowing for better dynamic overclocking. That technology is coming to the GeForce 700M mobile family. In notebooks, GPU Boost 2.0 is a combination of thermal and application monitoring. GPU Boost 2.0 is designed to reflect an important fact of 3D gaming — no two applications use the same amount of power. The variance can be significant, even within the same game. It's therefore possible for the GPU to adjust clocks dynamically in order to maximize frame rates. Put the two together, and NVIDIA believes it can substantially improve FPS speeds without compromising thermals or electrical safe operating margins."

bugnuts writes "Nearly all modern DSLRs use a Bayer filter to determine colors, which filters red, two greens, and a blue for each block of 4 pixels. As a result of the filtering, the pixels don't receive all the light and the pixel values must be multiplied by predetermined values (which also multiplies the noise) to normalize the differences. Panasonic developed a novel method of 'filtering' which splits the light so the photons are not absorbed, but redirected to the appropriate pixel. As a result, about twice the light reaches the sensor and almost no light is lost. Instead of RGGB, each block of 4 pixels receives Cyan, White + Red, White + Blue, and Yellow, and the RGB values can be interpolated."

Nerval's Lobster writes "Microsoft might want a piece of the mini-tablet market. The company has lowered the minimum screen resolution for Windows 8 tablets, from 1,366 x 768 pixels to 1024 x 768 pixels. "This doesn't imply that we're encouraging partners to regularly use a lower screen resolution," it wrote in an accompanying newsletter. "We understand that partners exploring designs for certain markets could find greater design flexibility helpful." As pointed out by ZDNet's Ed Bott—cited by other publications as the journalist who first noticed the altered guidelines—that lowered resolution "would allow manufacturers to introduce devices that are in line with the resolutions of the iPad Mini (1024 x 768) and the Kindle Fire and Google Nexus 7 (both 1280 x 800)." Whatever the contours of the smaller-tablet market, it's certainly popular enough to tantalize any potential competitor. But if Microsoft plunges in, it will face the same challenges that confronted it in the larger-tablet arena: lots of solid competitors, and not a whole lot of time to make a winning impression. There are also not-inconsiderable hardware challenges to overcome, including processor selection and engineering for optimal battery life."

Just when you thought it was safe to go back in the water, an anonymous reader writes in with news about a giant robot jellyfish. As if there weren't enough real jellyfish around to trigger our thalassophobia, researchers at Virginia Tech have created Cryo -- an eight-armed autonomous robot that mimics jelly movement with the help of a flexible silicone hat. The man-sized jellybot altogether dwarfs previous efforts, hence the upgrade from small tank to swimming pool for mock field tests. And unlike the passively propelled bots we've seen recently, Cryo runs on batteries, with the researchers hoping to better replicate the energy-efficient nature of jelly movement to eventually increase Cryo's charge cycle to months instead of hours. That's also the reason these robotic jellyfish are getting bigger -- because the larger they are, the further they can go."
