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."

MikeChino writes "Researchers at Germany's Doppelbock University just opened the door to the future of rapid prototyping technology by developing the world's first 3D-printed 3D printer. Dubbed the Ecophage, the duplicitous device is capable of using readily available materials to create copies of itself – albeit at a slightly smaller scale. Best of all, it's outfitted with a built-in material re-processor that can convert virtually any carbon-based substance into filament for 3d-printing."
hypnosec writes "Easter has brought some good news for Raspberry Pi fans in the US as the $25 Model A of the credit card sized computer is now available in the United States. Texas based Allied Electronics is the first local retailer selling the Raspberry Pi in the U.S. and has been selling the Pi through its online store. (There were companies selling the Raspberry Pi over eBay to U.S. users for a higher price tag earlier.) The Model A has sold out completely and as of this writing there is zero availability."
An anonymous reader writes "Ars Technica's Peter Bright reports on a Netware 3.12 server that has been decommissioned after over 16 years of continuous operation. The plug was pulled when noise from the server's hard drives become intolerable. From the article: 'It's September 23, 1996. It's a Monday. The Macarena is pumping out of the office radio, mid-way through its 14 week run at the top of the Billboard Hot 100, doing little to improve the usual Monday gloom...Sixteen and a half years later, INTEL's hard disks—a pair of full height 5.25 inch 800 MB Quantum SCSI devices—are making some disconcerting noises from their bearings, and you're tired of the complaints. It's time to turn off the old warhorse.'"
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."
RougeFemme writes "As part of a research project to develop low-cost artificial hands, DARPA has developed a two-hand robot that can almost change a tire. Research has mastered grasping objects with robotic hands; the next objective is to manipulate the objects once grasped. Research also continues on a neural interface, a direct link between a robotic arm and the human brain. The ultimate goal of the research project is to develop prostethics and robotic arms for wider use, by reducing cost and improving dexterity and machine vision."
mpthompson writes "Via RoboticsTrends' newsletter, RTS Lab in Tehran is developing Pars, which is an aerial rescue robot quadcopter designed to save potential drowning victims. The ship-based quadcopter responds instantly when alerted to potential victims in the ocean, locating them with thermal imaging sensors, and dispensing life preservers directly over them. The current prototype carries one life preserver, but they are working on a new model to carry three life preserver rings. Future models may dispense up to 15 self-inflating rings. A launching platform for use on ships has been designed, but more intriguing is an idea for a remote stand-alone launching platform. It's good to see innovative robot tech coming from a country that is not normally well covered in Western media."

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."
Electrons may not weigh anything, but it takes some heavy lifting, both literal and figurative, to point them in the right direction. Reader terrancem writes with this excerpt: "Energy efficiency gains are failing to keep pace with the Internet's rapid rate of expansion, says a new paper published in the journal Science. Noting that the world's data centers already consume 270 terawatt hours and Internet traffic volume is doubling every three years, Diego Reforgiato Recupero of the University of Catania argues for prioritizing energy efficiency in the design of devices, networks, data centers, and software development. Recupero highlights two approaches for improving efficiency: smart standby and dynamic frequency scaling or CPU throttling."
ceview writes "Researchers at Sheffield Centre for Robotics have demonstrated that a swarm of 40 robots can carry out simple fetching and carrying tasks. This is done by grouping around an object and working together to push it across a surface. They believe that this could provide opportunities for us mere humans to harness such power to do all sorts of things like safety — what like catching falling workers perhaps? Youtube action here."
sfcrazy writes "ZFS on Linux has reached what Brian Behlendorf calls an important milestone with the official 0.6.1 release. Version 0.6.1 not only brings the usual bug fixes but also introduces a new property called 'snapdev.' Brian explains, 'The snapdev property was introduced to control the visibility of zvol snapshot devices and may be set to either visible or hidden. When set to hidden, which is the default, zvol snapshot devices will not be created under /dev/. To gain access to these devices the property must be set to visible. This behavior is analogous to the existing snapdir property.'"
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."

First time accepted submitter szotz writes "The National Ignition Facility has one foot in national defense and another in the future of commercial energy generation. That makes understanding the basic justification for the facility, which boasts the world's most powerful laser system, more than a little tricky. This article in IEEE Spectrum looks at NIF's recent missed deadline, what scientists think it will take for the facility to live up to its middle name, and all of the controversy and uncertainty that comes from a project that aspires to jumpstart commercial fusion energy but that also does a lot of classified work. NIF's national defense work is often glossed over in the press. This article pulls in some more detail and, in some cases, some very serious criticism. Physicist Richard Garwin, one of the designers of the hydrogen bomb, doesn't mince words. When it comes to nuclear weapons, he says in the article, '[NIF] has no relevance at all to primaries. It doesn't do a good job of mimicking secondaries...it validates the codes in regions that are not relevant to nuclear weapons.'"
adeelarshad82 writes "After being tweaked and polished for months with the help of feedback from pro gamers and enthusiasts alike, Razer's Project Fiona has finally come of age. Re-named as Razer Edge Pro, this gaming tablet is way more than a mere plaything. Razer Edge Pro is a beast which packs a dual-core Intel Core i7-3517U Ivy Bridge processor with 8GB of RAM and an Nvidia GeForce GT 640M LE graphics card with 2GB of dedicated memory. All this in a small 7 by 11 by 0.8 inches wide frame which weighs only 2.14 pounds. Comparing the Razer Edge to anything else is tough, considering that it doesn't necessarily have a true competitor. However in a series of performance comparisons with other powerful tablets and ultraportable gaming laptops, Razer Edge performed better than the tablets but wasn't at par with ultraportable gaming laptops. For instance when comparing scores from 3DMark 11, the Edge Pro scored 2,503 points at entry settings and 504 points in extreme mode putting it ahead of both competing tablets, the Microsoft Surface Pro (1,055 Entry, 206 Extreme) and Samsung ATIV SmartPC (1,044 Entry, couldn't run at Extreme mode), but behind the gaming-focused laptops, like the the Maingear Pulse 11 (3,868 Entry, 724 Extreme) and the Razer Blade (3,458 Entry, 716 Extreme). What's baffling is that with all accessories incuded (gamepad dock and the console dock) the final price of the tablet is a cool $1,870, which most expensive than not only the two tablets tested but also the two gaming gaming laptops compared. It remains to be seen whether the Razer Edge Pro is something special or just on the edge of it."
Yesterday, Sony gave a presentation explaining a bit about the new PS4 hardware, the development environment (Windows 7 based IDE), and the changes to the Dual Shock controller. From the article: "The system is also set up to run graphics and computational code synchronously, without suspending one to run the other. Norden says that Sony has worked to carefully balance the two processors to provide maximum graphics power of 1.843 teraFLOPS at an 800Mhz clock speed while still leaving enough room for computational tasks. The GPU will also be able to run arbitrary code, allowing developers to run hundreds or thousands of parallelized tasks with full access to the system's 8GB of unified memory. ... The DualShock 4 controller that's standard on the PS4 eliminates one feature that was seldom used on the PS3 —the analog face buttons..." The trackpad will support two touch points, the rumble motors can be controlled more finely, and the analog sticks were tweaked for "reduced dead zone and better feeling tension that grips your thumbs."
damitr writes "With a lot of fanfare the Indian Government had launched a $35 tablet named Aakash (The Sky). Despite skepticism, the government went ahead with the project. But delays in production and deployment of the tablet have left the project in risk of failure. The manufacturer has been unable to supply the required 100,000 units, and a deadline of March 31 has been set. The new minister Pallam Raju says: 'Aakash is only a tablet... there are other such devices as well. While work will continue to develop it and increase its productivity, manufacturing is obviously a problem.'" For what it's worth, they did manage to ship 17,000 of them. It looks like meeting the deadline is impossible and the $35 tablet is dead.
Nerval's Lobster writes "One could argue that the University of Illinois' "Blue Waters" supercomputer, scheduled to officially open for business March 28, is lucky to be alive. The 11.6 petaflop supercomputer, commissioned by the University and the National Science Foundation (NSF), will rank in the upper echelon of the world's fastest machines—its compute power would place it third on the current list, just above Japan's K Computer. However, the system will not be submitted to the TOP500 list because of concerns with the way the list is calculated, officials said. University officials and the NSF are lucky to have a machine at all. That's due in part to IBM, which reportedly backed out of the contract when the company determined that it couldn't make a profit. The university then turned to Cray, which would have had to replace what was presumably a POWER or Xeon installation with the current mix of AMD CPUs and Nvidia GPU coprocessors. Allen Blatecky, director of NSF's Division of Advanced Cyberinfrastructure, told Fox that pulling the plug was a 'real possibility.' And Cray itself had to work to find the parts necessary for the supercomputer to begin at least trial operations in the fall of 2012."
