eBay Deploys 100TB of SSDs, Cuts Rackspace By Half 197

Lucas123 writes "eBay's QA division was facing mounting performance issues related to its exponential growth of virtual servers, so instead of purchasing more 15k rpm Fibre Channel drives, the company began migrating over to a pure SSD environment. eBay said half of its 4,000 VMs are now attached to SSDs. The changeout has improved the time it takes the online site to deploy a VM from 45 minutes to 5 minutes and had a tremendous impact on its rack space requirements. 'One rack [of SSD storage] is equal to eight or nine racks of something else,' said Michael Craft, eBay's manager of QA Systems Administration."

.NET Gadgeteer — Microsoft's Arduino Killer? 241

mikejuk writes ".NET Gadgeteer is a new open source platform, from Microsoft Research, based on the use of the .NET Micro Framework. It brings with it lots of hardware modules that are backed by object oriented software. You simply buy the modules you need — switches, GPS, WiFi etc — that you need and plug them together. The software, based on C#, is also open source, and comes with classes that let you use the modules without having to go 'low level.' Is this a competitor for the Arduino?"

Limits On Growth of Energy Use and Economies 482

snoop.daub writes "Dr. Tom Murphy, professor of astrophysics at UCSD, has a new blog called 'Do The Math,' and the first few posts are doozies. In the first, he shows the impossibility of continued exponential growth in energy use. Even if a new, 'free' energy source is developed, thermodynamic limits on efficiency mean that the heat associated with converting this energy into useful work will increase the temperature of the earth to unbearable levels within 300 years. In the second, he extends the argument to economic growth. The timescales there are faster, only 50-100 years. Fascinating stuff. Time to stop breeding, folks, or to get our butts into space."

Use Your Car To Power Your House 271

itwbennett writes "Nissan has developed a system that allows a vehicle to supply electricity to power a house during a power outage or shortage. A prototype of the charging system running on a Nissan Leaf electric car was unveiled in Japan on Tuesday. A two-way charging device that would typically convert the household electricity supply to a voltage suitable for charging the car's battery can be reversed to feed power back into the household circuit."

Swede Arrested For Building Nuclear Reactor 410

An anonymous reader writes "A 31 year old Swedish male was arrested for trying to build a nuclear reactor in his apartment. He got hold of radioactive material thru mail-order purchases and from smoke detectors. Police raided his apartment after he had contacted the Swedish Radiation Authority (Strålsäkerhetsmyndigheten) to inquire if it was legal to construct a nuclear reactor at home."

Middleboxes vs. the Internet's End-to-End Principle 90

arglebargle_xiv writes "The Internet was designed around the end-to-end principle, which says that functionality should be provided by end hosts rather than in the network itself. A new study of the effect of vast numbers of middleboxes on the Internet (PDF) indicates that this is no longer the case, since far too many devices on the Internet interfere with traffic in some way. This has serious implications for network (protocol) neutrality (as well as future IPv6 deployment) since only the particular variations of TCP that they know about will pass through them."

Ground-Based GPS Mimic Is Inch Perfect 140

holy_calamity writes "For several years the U.S. Air Force has used WiFi-router-sized boxes on a New Mexico missile range to create a GPS-like service to track munitions to the nearest inch. Now the Australian company behind the technology is rolling it out for civilians. One gold mine is already using the tech and specifications are being released so that GPS receiver manufacturers can adopt the technology. Locata hopes that construction sites, factories and city governments will all want to install their own high accuracy 'location hotspots.'"

NRC Study Lowers Hazard Estimate For Nuke Plants 168

JSBiff writes "With the incident at Fukushima causing much renewed concern about the risks of nuclear power this year, the NY Times brings news that the U.S. Nuclear Regulatory Commission has released the preliminary version of a safety report due out in April 2012, based upon new science about the behavior of Cesium-137. The report finds that the public health hazards of nuclear accidents at the types of reactor designs currently in common use are lower than previously thought, based upon a better understanding of the science behind earlier estimates."

3D Printing and the Replicator Economy 322

An anonymous reader writes "'Tea. Earl Grey. Hot,' is a command familiar to every Trek fan as representing everyday use of replicator technology. While its use on the show is simply sci-fi wizardry, the beginnings of that technology is now making it into homes, and could spark an industrial revolution. 'New 3D printing and other so-called additive manufacturing technologies are based on methods that industries developed over the past quarter century to rapidly create prototypes of mechanical parts for testing. But as these methods become increasingly sophisticated, demand is rising to use them to manufacture finished products, not only in factories but also at a boutique, one-off level for individuals. ... Already, 3D printing has been used to make tools and artworks, custom-fitted prosthetics for amputees, components for aviation and medical instruments, solid medical models of bones and organs based on MRI scans, paper-based photovoltaic cells, and the body panels for a lightweight hybrid automobile.'"

Google Running 900,000 Servers 127

1sockchuck writes "How many servers is Google using? The company won't say, but a new report places the number at about 900,000. The estimate is based on data Google shared with researcher Jonathan Koomey, for a new report on data center power use. The data updates a 2007 report to Congress, and includes a surprise: data centers are using less energy than projected, largely due to the impact of the recession (buying fewer servers) and virtualization."

Radio Energy Harvested With Inkjet-Printed Antenna 164

judgecorp writes "Everlasting green energy for RF tags and other low-power devices could be possible as scientists have harvested energy from ambient radio waves using cheap antennas printed by an ordinary inkjet. The scientists, from Georgia Tech, started at 100MHz but have now produced systems which scavenge power at up to 60GHz, allowing them to draw power from most of today's major radio technologies."

Volunteer Towns Sought For Nuclear Waste 279

Hugh Pickens writes "Brian Wingfield writes in Bloomberg that the Blue Ribbon Commission on America's Nuclear Future has sent a draft report to Energy Secretary Steven Chu recommending that US communities should be encouraged to vie for becoming a federal nuclear-waste site as a way to end a decades-long dilemma over disposing of spent radioactive fuel and says this 'consent-based' approach will help cut costs and end delays caused when the federal government picks a site over the objections of local residents, 'This means encouraging communities to volunteer (PDF) to be considered to host a new nuclear-waste management facility,' says the commission. Chu named the panelists after Obama canceled plans to build a permanent repository at Nevada's Yucca Mountain after the Yucca site was opposed by politicians from the state. 'The United States has traveled nearly 25 years down the current path only to come to a point where continuing to rely on the same approach seems destined to bring further controversy, litigation, and protracted delay,' says the report. The Blue Ribbon Commission cited as a 'success' the US Waste Isolation Pilot Plant near Carlsbad, New Mexico, which has accepted and disposed of some defense-related nuclear waste for more than a decade demonstrating that that 'nuclear wastes can be transported safely over long distances and placed securely in a deep, mined repository.' With the right incentives, 'there will be a great deal of support' for a waste site near the New Mexico facility, says former Senator Pete Domenici."

No Set-Top TV Device Market Domination For Google 133

itwbennett writes "According to a report in the Wall Street Journal, returns of the Logitech Revue (Google's set-top box) exceeded sales in the first quarter. Explaining why sales were so poor, Logitech Chairman Guerrino De Luca went way out on a limb, saying: 'There was a significant gap between our price and the value perceived by the consumer.' So significant that 'Logitech must take a $34 million charge in the first quarter, which more than comprises the company's Q1 net loss of $30 million,' writes blogger Chris Nerney. 'In other words, Google TV is pushing Logitech into the red!'"

WD's Terabyte Scorpio Notebook Drive Tested 100

MojoKid writes "Recently, Western Digital stepped out and announced their new 1TB 9.5mm Scorpio Blue 2.5-inch notebook drive. The announcement was significant in that it's the first drive of this capacity to squeeze that many bits into an industry standard 9.5mm, 2.5" SATA form-factor. To do this, WD drove areal density per platter in their 2.5" platform to 500GB. The Scorpio Blue 1TB drive spins at only 5400RPM but its performance is actually surprising. Since areal density per platter has increased significantly, the drive actually bests some 7200RPM drives."

Beyond HDTV 354

The Hub writes "The Economist writes a thoughtful article about the next generation of HDTVs and how they will provide resolutions beyond 1080p. The drive for higher resolution is driven in part by the demands of 3D content. Also, some see streaming higher resolution content to the home as a way to make up for declining DVD sales. This would mean the studios would have to better embrace services such as Netflix or stream directly to the consumer. Mind you, picture quality is driven by more than the number of pixels."

MIT Unveils Sun-Free Photovoltaics 103

An anonymous reader writes "Researchers at MIT just unveiled a new solar power generator that doesn't need sunlight to function. The button-sized power generator can tap energy from heat, the sun's rays, a hydrocarbon fuel, or a decaying radioisotope, and it can run three times longer than a lithium-ion battery of the same weight. It is hoped that the technology may one day be used to generate power for spacecraft on long-term missions where sunlight may not be available."

Raspberry Pi $25 PC Goes Into Alpha Production 137

An anonymous reader writes "Game developer David Braben caused geeks to get excited back in May when he announced plans to develop and release a $25 PC. It is called the Raspberry Pi and takes the form of a USB stick that can be plugged into the HDMI port of a display ready to act as a fully-functional PC. Two months on and the spec of the PCB layout has been finalized and an alpha release has been sent to manufacture. Any doubts this PC wasn't going to happen should now disappear as this alpha board is expected to be almost the same as the final production unit. Although we don't know a release date as of yet, the Raspeberry Pi Foundation is promising images of the alpha boards in a couple of weeks."

Hackers' Flying Drone Now Eavesdrops On GSM Phones 90

Sparrowvsrevolution writes "At the Black Hat and Defcon security conferences in Las Vegas next week, Mike Tassey and Richard Perkins plan to show the crowd of hackers a year's worth of progress on their Wireless Aerial Surveillance Platform, or WASP, the second year Tassey and Perkins have displayed the 14-pound, six-foot-long, six-foot wingspan unmanned aerial vehicle. The WASP, built from a retired Army target drone converted from a gasoline engine to electric batteries, is equipped with an HD camera, a cigarette-pack-sized on-board Linux computer packed with network-hacking tools, including the BackTrack testing toolset and a custom-built 340 million word dictionary for brute-force guessing of passwords, and eleven antennae. On top of cracking Wi-Fi networks, the upgraded WASP now also performs a new trick: impersonating the GSM cell phone towers used by AT&T and T-Mobile to trick phones into connecting to the plane's antenna rather than their carrier, allowing the drone to record conversations and text messages on 32 gigs of storage."
