BeagleBone Black Ships With New Linux 3.8 Kernel
Posted by: DeviceGuru
BeagleBoard.org has begun shipping its faster, cheaper BeagleBone Black SBC with a new Linux 3.8 kernel, supporting Device Tree technology for more streamlined ARM development. The $45 BeagleBone Black runs Linux or Android on a 1GHz TI Sitara AM3359 SOC, doubles the RAM to 512MB of its predecessor, and adds a micro-HDMI port. The updated kernel gives the BeagleBone Black access to a new Direct Rendering Manager (DRM) display driver architecture, as well as full support for the Device Tree data structure introduced to streamline ARM development in Linux 3.7. The project was hesitant to move up to such a recent kernel, but decided it was time to bite the bullet and support the Device Tree. By doing the hard work of switching to Device Tree now, BeagleBoard.org and its developer community can save a lot of configuration and maintenance headaches down the line, says BeagleBoard.org co-founder Jason Kridner. Fortunately, a modified 3.2 kernel 'coming soon' should provide the necessary bridge from the old cape driver architecture to the new one.
Google Releases Glass Factory System Image, Rooted Bootloader
Posted by: Krystalo
In a nod towards the modding community and hackers in general, Google has released the first factory system image and rooted bootloader for the latest version, XE5, of Google Glass. Nevertheless, the company is at the same time warning that using these downloads will result in a voided warranty for the experimental device.
Intel Claims Haswell Architecture Offers 50% Longer Battery Life vs. Ivy Bridge
Posted by: MojoKid
As with any major CPU microarchitecture launch, one can expect the usual 10~15% performance gains, but Intel apparently has put its efficiency focus into overdrive. Haswell should provide 2x the graphics performance, and it's designed to be as power efficient as possible. In addition, the company has further gone on to state that Haswell should enable a 50% battery-life increase over last year's Ivy Bridge. There are a couple of reasons why Haswell is so energy-efficient versus the previous generation, but the major reason is moving the CPU voltage regulator off of the motherboard and into the CPU package, creating a Fully Integrated Voltage Regulator, or FIVR. This is a far more efficient design and with the use of 'enhanced' tri-gate transistors, current leakage has been reduced by about 2x — 3x versus Ivy Bridge.

NVIDIA GeForce GTX 780 Offers 2,304 Cores For $650
Posted by: Vigile
When NVIDIA released the GTX Titan in February, it was the first consumer graphics card to use the GK110 GPU from NVIDIA that included 2,688 CUDA cores / shaders and an impressive 6GB of GDDR5 frame buffer. However, it also had a $1000 price tag that was the limiting specification for most gamers. With today's release of the GeForce GTX 780 they are hoping to utilize more of the GK110 silicon they are getting from TSMC while offering a lower cost version with performance within spitting range. The GTX 780 uses the same chip but disables a handful more compute units to bring the shader count down to 2,304 — still an impressive bump over the 1,536 of the GTX 680. The 384-bit memory bus remains though the frame buffer is cut in half to 3GB. Overall, the performance of the new card sits squarely between the GTX Titan ($1000) and AMD's Radeon HD 7970 GHz Edition ($439), just like its price. The question is, are PC gamers willing to shell out $220+ dollars MORE than the HD 7970 for somewhere in the range of 15-25% more performance?
Meet Pidora, the New Official Fedora Remix For Raspberry Pi
Posted by: An
Today Fedora and the Seneca Centre for Development of Open Technology (CDOT) announced the release of Pidora 18, an optimized Fedora remix for the Raspberry Pi. It's based on a brand new build of Fedora for the ARMv6 architecture with greater speed and includes packages from the Fedora 18 package set. It's also the launch of the Pidora name. (The older version of Fedora for the Pi was called the Fedora Raspberry Pi Remix.)
First Government Lawsuit Against a Patent Troll
Posted by: walterbyrd
Late last year, a vigorous and secretive patent troll began sending out thousands of letters to small businesses all around the country, insisting that they owed between $900 and $1,200 per worker just for using scanners. The brazen patent-trolling scheme, carried out by a company called MPHJ technologies and dozens of shell companies with six-letter names, has caught the attention of politicians. MPHJ and its principals may have gone too far. They're now the subject of a government lawsuit targeting patent trolling—the first ever such case. Vermont Attorney General William Sorrell has filed suit in his home state, saying that MPHJ is violating Vermont consumer-protection laws.
Will Robots Take Over the Data Center?
Posted by: 1sockchuck
Robotics are beginning to be integrated into data center management, creating the potential for a fully automated, robot-driven data center. What might a robot-controlled 'lights-out' data center look like? The racks will be taller, as robotics systems can reach higher to manage servers. Robotic equipment would be mounted on rails that allow them to find and move hardware. Early examples of this are seen in tape libraries, but the concepts could be applied to other data center equipment. Amazon and Google are said to be among those looking at ways to create a fully automated data center. AOL says it has already built an unmanned data center. Data Center Knowledge looks at the challenges and opportunities in robot-controlled data centers, including how staff roles would evolve.
Congressional Report: US Power Grid Highly Vulnerable To Cyberattack
Posted by: An
Despite warnings that a cyberattack could cripple the nation's power supply, a U.S. Congressional report (PDF) finds that power companies' efforts to protect the power grid are insufficient. Attacks are apparently commonplace, with one utility claiming they fight off some 10,000 attempted attacks every month. The report also found that while most power companies are complying with mandatory standards for protection, few do much else above and beyond that to protect the grid. 'For example, NERC has established both mandatory standards and voluntary measures to protect against the computer worm known as Stuxnet. Of those that responded, 91% of IOUs [Investor-Owned Utilities], 83% of municipally- or cooperatively-owned utilities, and 80% of federal entities that own major pieces of the bulk power system reported compliance with the Stuxnet mandatory standards. By contrast, of those that responded to a separate question regarding compliance with voluntary Stuxnet measures, only 21% of IOUs, 44% of municipally- or cooperatively-owned utilities, and 62.5% of federal entities reported compliance.'
Working Handgun Printed On a Sub-$2,000 3D Printer
Posted by: Just
a couple of Wisconsin hobbyist gunsmiths have already managed to adapt Defense Distributed's so-called Liberator firearm and print it on a $1,725 Lulzbot 3D printer, a consumer grade machine that's far cheaper than the industrial quality Stratasys machine Defense Distributed used. They then proceeded to record their cheaper gun (dubbed the 'Lulz Liberator') firing nine .380 rounds without any signs of cracking or melting. Eight of the rounds were fired from a single plastic barrel. (Defense Distributed only fired one through its prototype.) In total, the Lulz Liberator's materials cost around $25 and were printed over just 48 hours.
NWS Announces Big Computer Upgrade
Posted by: riverat1
After being embarrassed when the Europeans did a better job forecasting Sandy than the National Weather Service Congress allocated $25 million ($23.7 after sequestration) in the Sandy relief bill for upgrades to forecasting and supercomputer resources. The NWS announced that their main forecasting computer will be upgraded from the current 213 TeraFlops to 2,600 TFlops by fiscal year 2015, over a twelve-fold increase. The upgrade is expected to increase the horizontal grid scale by a factor of 3 allowing more precise forecasting of local features of weather. The some of the allocated funds will also be used to hire some contract scientists to improve the forecast model physics and enhance the collection and assimilation of data.
Ask Slashdot: Wiring Home Furniture?
Posted by: b1tbkt
So it seems that furniture manufacturers have not yet acknowledged the realities of modern life. Kitchen tables could benefit greatly from built-in concealable receptacles. Even more obvious is the need for electrical wiring in couches and coffee tables. I realize that there are safety (fire) concerns but as it stands most families that I know already have power cords for laptops, tables and phones draped over, under and through their couches at any given point. If someone wanted to wire their furniture with AC or some type of standardized LV DC system, what are some dangers to watch for and what, if any, specialized hardware exists for the purpose?

Charge Your Cellphone In 20 Seconds (Eventually)
Posted by: New
An 18-year-old from Saratoga, California has won an international science fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds. The fast-charging device is a so-called supercapacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds its charge for a long time. What's more, it can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries, according to the inventor Eesha Khare.
Data Center Managers Weary of Whittling Cooling Costs
Posted by: Nerval's
suggests something it calls 'green fatigue' is setting in when it comes to making data centers greener. 'Green fatigue' is exactly as it sounds: managers are getting tired of the increasingly difficult race to chop their PUE, or Power Usage Effectiveness. The PUE is a measure of a data center's efficiency. The lower the PUE, the better — and Microsoft and Google, with nearly limitless resources, have set the bar so high (or low, depending on your perspective) that it's making less-capitalized firms frustrated. Just a few years ago, the Uptime Institute estimated that the average PUE of a data center was around 2.4, which meant for every dollar of electricity to power a data center, $1.4 dollars were spent to cool it. That dropped to 1.8 recently, an improvement to be sure. But then you have companies such as Google and Microsoft building data centers next to rivers for cheap hydroelectric power in remote parts of the Pacific Northwest and reporting insanely low PUEs (below 1.1 in some cases). The Institute latest survey of data center operators shows only 50 percent of respondents in North America said they considered energy efficiency to be very important to their companies, down from 52 percent last year and 58 percent in 2011.
Arduino Branches Out, With a Plug-and-Program Robot
Posted by: mikejuk
The new Arduino robot looks a bit like a robot vacuum cleaner, but it has a lot more going for it and it certainly doesn't suck — well not unless you add an air pump to it. As always, the Arduino Robot is completely open source and comes as an easy to assemble kit involving no soldering, just some plugging in of components. It consists of two circular boards, 19cm in diameter, each with its own Arduino controller. They fit together to create a stack about 10cm tall. The bottom board has two wheels and motors which allow it to move in any direction. The top board contains lots of sensors and a central display. The two communicate via a serial connection. There is also a lot of space for expansion. There is a new library which can be downloaded to help write programs for this fairly sophisticated robot. There is only one big problem with the Arduino robot — you can't buy one at the moment. If you really can't wait, until early July when they should start shipping from the Arduino shop and from distributors, then you will have to get to the Maker Faire San Mateo (May 17-19) where they are being demonstrated and sold.
RPiCluster: Another Raspberry Pi Cluster, With Neat Tricks
Posted by: New
The RPiCluster is a 33-node Beowulf cluster built using Raspberry Pis (RPis). The RPiCluster is a little side project I worked on over the last couple months as part of my dissertation work at Boise State University. I had need of a cluster to run a distributed simulator I've been developing. The RPiCluster is the result. I've written an informal document on why I built the RPiCluster, how it was built, and how it performs as compared to other platforms. I also put together a YouTube video of it running an MPI parallel program I created to demo the RGB LEDs installed on each node as part of the build. While there have certainly been larger RPi clusters put together recently, I figured the Slashdot community might be interested in this build as I believe it is a novel approach to the rack mounting and power management of RPis.
Robotic Bartender Assembles Your Drink, Monitors Alcohol Consumption
Posted by: First
You're at a busy bar. You order your personalized cocktail through a smart phone app; a drink dispenser measures out the beverage according to your instructions and a Kuka robotic arm give it a shake (or stir), while another garnishes it with a slice of lemon; the made-to-order concoction is delivered to your waiting hand via a slick little ten-lane conveyor belt. The 'mixology system' tracks your order from start to finish: a large display behind the bar shows you the number of drinks ahead of yours in the queue, the current wait time, and lets you know when your drink is ready to be picked up. It also shows you what's popular to drink tonight among both the ladies and the gents in the crowd, and lets you influence drinking trends in real-time by incorporating your suggested tweaks on popular recipes.
AMD Announces Radeon HD 8970M High-End Mobile GPU

Data Center Operators Double As Energy Brokers
Posted by: mattOzan
When data centers first opened in the 1990s, the tenants paid for space to plug in their servers with a proviso that electricity would be available. As computing power has soared, so has the need for electricity, turning that relationship on its head: electrical capacity is often the central element of lease agreements, and space is secondary. While lease arrangements are often written in the language of real estate, they are essentially power deals. 'Since tenants on average tend to contract for around twice the power they need, Mr. Tazbaz said, those data centers can effectively charge double what they are paying for that power. Generally, the sale or resale of power is subject to a welter of regulations and price controls. For regulated utilities, the average
Drones: Coming Soon To the New Jersey Turnpike?

The FAA predicts 30,000 drones will patrol the US skies by 2020, but New Jersey drivers could see these unmanned aerial vehicles hovering above the New Jersey Turnpike and Garden State Parkway much sooner than that. New Jersey lawmakers from both Republican and Democratic parties have introduced a number of bills to tackle the drones issue before the federal government starts issuing the first domestic drone permits in September 2015.
NeuroGaming Conference Profiles the Rise of Brain-Computer Interfaces
Posted by: kkleiner
The first NeuroGaming Conference and Expo took place at the beginning of May to showcase the convergent technologies that are paving the way toward gaming with your mind. Tech news has been dominated with stories about Google Glass and the Oculus Rift, which was on display for attendees to test out. Other technologies that utilize EEG are opening up possibilities of a controller-free gaming experience into virtual realities with unlimited potential. 'Deeper questions surrounding the morality of neurogames will be sure to stir debate. As virtual reality technology inches closer to lifelike resolution, should gamers simulate themselves as characters engaged in acts of violence or criminal activity? It’s unpredictable what these games could uncover about the user as neurogames gain insight into a users’ psyche and how they respond to stimuli at a subconscious level. For instance, a game could uncover how its user particularly enjoys shooting at civilians in gameplay. Games might even become expert at diagnosing psychiatric disorders. As computers become exponentially more powerful, game resolution could fully mimic our ever-present reality.'
