New Solar Cell Sets Record For Energy Efficiency 165

Lucas123 writes "After three years of work, German and French researchers have achieved a new world record on converting sunlight to energy through a photovoltaic cell, achieving a 44.7% rate of efficiency, which was measured at a concentration of 297 suns. The efficiency rating means the solar cell collects 44.7% of the sun's spectrum's energy, from ultraviolet to the infrared spectrum, which is converted into electrical energy. The team of researchers said the technology places them on the path to achieving their roadmap of 50% efficiency in solar energy conversion."

Malware Now Hiding In Graphics Cards 125

mask.of.sanity writes "Researchers are closing in on a means to detect previously undetectable stealthy malware that resides in peripherals like graphics and network cards. The malware was developed by the same researchers and targeted host runtime memory using direct memory access provided to hardware devices. They said the malware was a 'highly critical threat to system security and integrity' and could not be detected by any operating system."

Video The MinnowBoard is a Low-Cost, Open Hardware Single-Board Computer (Video) 84

Out in the Northeast Texas town of Ft. Worth, a company called CircuitCo started making something they called the BeagleBoard -- an open source hardware single-board computer for educators and experimenters. Now, with help and support from Intel, they're making and supporting the Atom-based MinnowBoard, which is also open source, and comes with Angstrom Linux to help experimenters get started with it. David Anders is the Senior Embedded Systems Engineer at CircuitCo. Slashdot's Timothy Lord met David at LinuxCon North America 2013 in New Orleans and made this video of him talking about the recently-released MinnowBoard and the more mature BeagleBoard.

Undiscovered Country of HFT: FPGA JIT Ethernet Packet Assembly 452

michaelmalak writes "In a technique that reminds me of the just-in-time torpedo engineering of Star Trek VI: The Undiscovered Country, a company called Argon Design has "developed a high performance trading system" that puts an FPGA — and FPGA-based trading algorithms — right in the Ethernet switch. And it isn't just to cut down on switch/computer latency — they actually start assembling and sending out the start of an Ethernet packet simultaneously with receiving and decoding incoming price quotation Ethernet packets, and decide on the fly what to put in the outgoing buy/sell Ethernet packet. They call these techniques 'inline parsing' and 'pre-emption.'"

AMD Unveils New Family of GPUs: Radeon R5, R7, R9 With BF 4 Preorder Bundle 188

MojoKid writes "AMD has just announced a full suite of new GPUs based on its Graphics Core Next (GCN) architecture. The Radeon R5, R7, and R9 families are the new product lines aimed at mainstream, performance, and high-end gaming, respectively. Specs on the new cards are still limited, but we know that the highest-end R9 290X is a six-billion transistor GPU with more than 300GB/s of memory bandwidth and prominent support for 4K gaming. The R5 series will start at $89, with 1GB of RAM. The R7 260X will hit $139 with 2GB of RAM, the R9 270X and 280X appear to replace the current Radeon 7950 and 7970 with price points at $199 and $299, and 2GB/3GB of RAM, and then the R9 290X, at an unannounced price point and 4GB of RAM. AMD is also offering a limited preorder pack, that offers Battlefield 4 license combined with the graphics cards, which should go on sale in the very near future. Finally, AMD is also debuting a new positional and 3D spatial audio engine in conjunction with GenAudio dubbed 'AstoundSound,' but they're only making it available on the R9 290X, R9 280X, and the R9 270X."

Valve Announces Hardware Beta Test For 'Steam Machine' 271

Valve's second major living-room-gaming announcement landed today: they have produced a prototype model of their first "Steam Machine." They've made 300 units, and they'll be sending the machines to users in a very limited beta test. Valve hastens to add that this device isn't the only Steam-focused hardware: "Entertainment is not a one-size-fits-all world. We want you to be able to choose the hardware that makes sense for you, so we are working with multiple partners to bring a variety of Steam gaming machines to market during 2014, all of them running SteamOS." They haven't released specs, but they guaranteed the prototypes will ship this year. They explicitly permit using it in any way — swapping parts, changing the OS, installing any software, etc. "The specific machine we're testing is designed for users who want the most control possible over their hardware. Other boxes will optimize for size, price, quietness, or other factors."

Amazon Launches Kindle Fire HDX Tablets 88

New submitter casab1anca writes "In classic Amazon fashion, without much fanfare, a bunch of new tablets just popped up on their homepage today. The new range, dubbed HDX, is available in the usual 8.9" and 7" versions, with improved hardware and software, but perhaps equally interesting is the revamped 7" Fire HD from last year, which goes for just $139 now." Compared to the Kindle Fire HD, the new models feature a jump in display density (216 PPI to 323 PPI for the 7" and 254 to 339 PPI for the 9"), a switch from a dual-core TI OMAP Cortex-A9 (at 1.2/1.5GHz) to a quad-core 2.2GHz Qualcomm Snapdragon, and a bump from 1G to 2G of RAM. On the software side, Android has been upgraded from 4.0 to 4.2.2 and Amazon added a few new features to their applications. Businessweek has an interview with Jeff Bezos running today too (starting a bit down the first page).

The Chip That Changed the World: AMD's 64-bit FX-51, Ten Years Later 259

Dputiger writes "It's been a decade since AMD's Athlon 64 FX-51 debuted — and launched the 64-bit x86 extensions that power the desktop and laptop world today. After a year of being bludgeoned by the P4, AMD roared back with a vengeance, kicking off a brief golden age for its own products, and seizing significant market share in desktops and servers." Although the Opteron was around before, it cost a pretty penny. I'm not sure it's fair to say that the P4 was really bludgeoning the Athlon XP though (higher clock speeds, but NetBurst is everyone's favorite Intel microarchitecture to hate). Check out the Athlon 64 FX review roundup from 2003.

Why Is Microsoft Setting More Money On Fire With Surface 2? 616

Nerval's Lobster writes "Never mind that sales of the original Surface totaled a pitiful $853 million in its first few months of release, or that the tablet failed to make Microsoft an up-and-coming player (or any kind of player, really) in the mobile-device wars: Microsoft's now rolling out Surface 2 and Surface Pro 2, which feature upgraded specs and accessories but no radical adjustments to the first generation. Why would Microsoft pour good money after bad? The answer could be outgoing Microsoft CEO Steve Ballmer, who late last year released a memo suggesting that Microsoft was evolving into a 'devices and services' company. 'There will be times when we build specific devices for specific purposes, as we have chosen to do with Xbox and the recently announced Microsoft Surface,' he wrote. 'In all our work with partners and on our own devices, we will focus relentlessly on delivering delightful, seamless experiences across hardware, software and services.' That meant Surface (then on the cusp of release) was clearly a harbinger of the company's future direction — and canceling the project after the first generation would have been a stinging refutation of Ballmer's strategy. By spending the money and resources on a second device generation, Microsoft manages to save a little bit of face, albeit at considerable cost. But imagine the hilarity that'll ensue if this second generation goes down in a huge ball of flames like the first."

Middle-Click Paste? Not For Long 729

An anonymous reader writes "Select to copy and middle-click to paste. That's very convenient usability feature associated with UNIX graphical environments. But it is confusing for new users, so the ability to middle-click paste was briefly removed from GNOME 3.10. It was restored few days later, but with clear message: middle-click paste will be permanently removed from next GNOME version." I hope that "we'll defer this change until the next cycle" also means that it's getting re-thought, rather than just delayed.

Xbox One's HDMI Pass-Through Can Connect PS4, PCs and More 171

MojoKid writes "The Xbox One has both HDMI-in and HDMI-out capability. The point of HDMI-in is to allow you to hook up a cable box, with output then running from the Xbox One to your television. As it turns out, however, that's not the only thing the Xbox One can do. Since the HDMI-in port is a standard option, it can accept video input from a PS4 and also accept a video stream from a PC. According to Xbox senior director of product management, Albert Panello, "any application can be snapped to a game... this could be the live TV feed, so if you wanted to play Ryse and Killzone (a PS4 exclusive), you could snap that." Keep in mind, snapping a title to the Xbox One doesn't mean that you can actually keep using Xbox One controllers in the game. If you want to snap in a PS4 game, you still need PS4 controllers. If you want to hook a PC into the Xbox One's video output, you still need mouse and keyboard, though if the Xbox One's controllers are eventually PC compatible, then you might be able to use the same controller on both platforms without doing much more than flipping a switch."

CCC Says Apple iPhone 5S TouchID Broken 481

hypnosec writes with word that the Chaos Computer Club claims to have "managed to break Apple's TouchID using everyday material and methods available on the web. Explaining their method on their website, the CCC hackers have claimed that all they did was photograph a fingerprint from a glass surface, ramped up the resolution of the photographed fingerprint, inverted and printed it using thick toner settings, smeared pink latex milk or white woodglue onto the pattern, lifted the latex sheet, moistened it a little and then placed it on the iPhone 5S's fingerprint sensor to unlock the phone."

Valve Announces Steambox, Sort Of 252

wbr1 writes "A new page has appeared over at Steam with this slightly cryptic text, a countdown, and an image of a console controller. 'Last year, we shipped a software feature called Big Picture, a user-interface tailored for televisions and gamepads. This year we've been working on even more ways to connect the dots for customers who want Steam in the living-room. Soon, we'll be adding you to our design process, so that you can help us shape the future of Steam.' It appears Gabe Newell wants to throw his hat in the console ring now with the Xbox One and PS4 about to be released. The countdown to the announcement is targeted at Monday."

Ultimaker Debuts Ultimaker 2 3D Printer With Open Source Cura Software 53

MojoKid writes "3D Printing start-up Ultimaker announced its second generation printer, the Ultimaker 2. The new printer features significant redesigns from the first iteration of the Ultimaker. The company says that the new machine is more accurate, more efficient, and it's even quieter at 49dB. Specifically, the Ultimaker 2 has a new CNC-milled case (that's all white with glowing sidewalls) with an OLED display, and its glass and aluminum build platform is designed to cool quickly so you can peel completed projects off more easily. The Ultimaker 2 can print with multiple materials, including PLA, ABS, and PVA, and is WiFi-compatible so you can print from a mobile device or computer. Ultimaker is also launching its Cura open source software, which the company claims can pre-process 3D files some 60 times faster than other open source applications and makes it easy to load and work with 3D files."

Never Underestimate the Bandwidth of a Suburban Filled With MicroSD Cards 208

toygeek writes "If you've been in IT long enough, you're bound to have heard the phrase 'Never underestimate the bandwidth of a station wagon filled with backup tapes.' These days moving data has become so much easier; We've surpassed baud rates and are into Gbps fiber on the backbones, and even in some homes. So, what's the modern equivalent to this, and what does it take to make the OC fiber connections cringe? Follow along as we theoretically stuff MicroSD cards into a Chevy Suburban and see what happens, and take sneakernet to a whole new level."

Turning a Smart Phone Into a Microscope 43

MTorrice writes "By attaching a lightweight, inexpensive device to the back of a smart phone, scientists can convert the phone into a sensitive fluorescence microscope. The attachment [paper abstract] allows the phone's camera to take pictures of single nanoparticles and viruses, possibly providing a portable diagnostic tool for health care workers in developing countries. For example, doctors in remote regions could use the technique to measure HIV viral loads in patients' blood samples, allowing the doctors to easily monitor disease progression and determine the best course of treatment."

Robotics Research Lab Willow Garage Shutting Down? 23

New submitter moglito writes "Willow Garage is/was acknowledge by many to be one of the best places for robotics research these days. Besides developing the PR2 it made itself a name for creating the open-source Robot Operating System ROS. But now it seems to be shutting down. [From a posting on the Willow Garage site:] 'Scott Hassan, founder of both Willow Garage and Suitable Technologies, said, 'I am excited to bring together the teams of Willow Garage and Suitable Technologies to provide the most advanced remote presence technology to people around the world.' Willow Garage will continue to support customers of its PR2 personal robotics platform and sell its remaining stock of PR2 systems. Interest in PR2 systems or support should continue to be directed to Willow Garage through its portal at www.willowgarage.com.'"
