mikejuk writes "A new paper from Microsoft Research (PDF) suggests a radical but slightly mad scheme for dealing with some of the more basic problems of the data center. Rather than build server farms that produce a lot of waste heat, why not have distributed Data Furnaces, that heat home and offices at the same time as providing cloud computing? This is a serious suggestion and they provide facts and figures to make it all seem viable. So when it gets cold all you have to do is turn up the number crunching ..."

CWmike writes "With an eye toward helping tomorrow's data-deluged organizations, IBM researchers have created a super-fast storage system capable of scanning in 10 billion files in 43 minutes. This system handily bested their previous system, demonstrated at Supercomputing 2007, which scanned 1 billion files in three hours. Key to the increased performance was the use of speedy flash memory to store the metadata that the storage system uses to locate requested information. Traditionally, metadata repositories reside on disk, access to which slows operations. (See IBM's whitepaper.)"

Stirfry192 sends this excerpt from an article discussing the Obama Administration's funding of renewable energy projects that are experimenting with hydrokinetics: "Currently, the Department of Energy has a mandate to spend $50 million a year on backing such research. For its part, the Federal Energy Regulatory Commission has approved 72 permits for pilot projects over the past two years , according to its records. Ocean Renewable Energy Power Company, LLC , which has plans to build the largest ocean-based system in the U.S., is one of the companies that has won such funding. ... Virtually all hydrokinetic turbines resemble giant manual lawnmowers, a design patented by Alexander Gorlov of Northeastern University in 2001. [CEO Chris Sauer] calls what his company uses an 'advance cross-flow' model, and he says each of his 150 kilowatt units could power 50 to 75 homes. ... The company plans to install one of its 150 kilowatt turbines this year, and four next year, anchoring them near the floor of the bay, and progressively build out to 3.2 megawatts by 2014. The system would tie into Bangor Hydro Electric Co. grid."

Trailrunner7 writes "Security researcher Charlie Miller, widely known for his work on Mac OS X and Apple's iOS, has discovered an interesting method that enables him to completely disable the batteries on Apple laptops, making them permanently unusable, and perform a number of other unintended actions. The method, which involves accessing and sending instructions to the chip housed on smart batteries, could also be used for more malicious purposes down the road. Miller discovered the default passwords set on the battery at the factory to change the battery into unsealed mode and developed a method that let him permanently brick the battery as well as read and modify the entire firmware. 'You can read all the firmware, make changes to the code, do whatever you want. And those code changes will survive a reinstall of the OS, so you could imagine writing malware that could hide on the chip on the battery. You'd need a vulnerability in the OS or something that the battery could then attack, though,' Miller said."

siliconbits writes "GE Global Research announced earlier today that it has managed to cram up to 500GB worth of data on a standard DVD-size disc, an increase in storage density of roughly 100x. What's more, the tech arm of conglomerate General Electric Company says that the storage solution will record data at the same speed as Blu-ray discs while increasing storage capacity by 25 times. The Blu-ray Disk Association says that the commonly available 12x speed Blu-ray writers have a maximum writing speed of up to 400Mbps (or 50MBps) which means that in theory, it would take just over three hours to fill that new holographic hard disk. GE has confirmed that its R&D and licensing team will be sampling the media to qualified partners that may be interested in licensing the technology."

siliconbits writes "Two months after Apple joined the Bluetooth special interest group board, the company launched the world's first truly mainstream Bluetooth 4.0 devices, namely the new Macbook Air & Mac Mini 2011 editions. The products came only one year after the official core specifications of Bluetooth 4.0 were adopted and it looks likely that Apple fast-tracked Bluetooth 4.0's adoption so that the forthcoming iPhone 5 can use this technology with at least one Apple product. This could mean that the manufacturer is considering giving up on NFC altogether, a technology embraced by all of its rivals."

An anonymous reader writes "With two 17" HD LED displays, the SpaceBook goes against every trend in laptop design I can think of (well, apart from the Core i7 and Core i5 processors). It's more than 1.7" thick, weighs more than 4.5 kilograms, and apparently has the world's largest laptop screen space. As odd as lugging a 4.5kg laptop around sounds, it can actually make sense in some situations. Sure, there are now plenty of powerful laptops that can replace a desktop PC. But for some of us, it's never the same as sitting in front of a desktop. Especially if you're used to having two screens. Someone must think there's a market for the twin-screen laptop — this isn't the first. Lenovo brought one out a couple of years ago. Given the number of people who prefer a multi-monitor setup, surely someone can come up with a lighter, less cumbersome, and cheaper design?"

Lucas123 writes "Adding NAND flash memory to a PC does more for performance than DRAM and costs less, according to a new study. As the price difference between the two memory types widens, NAND flash will become the memory of choice in the PC. The effects of NAND flash adoption are already being felt in the DRAM market, as revenue in 2011 is expected to decline 11.8%."

An anonymous reader writes "I have a collection of large projects (Indesign files with associated images), which are typically 40GB to 60GB each. In this current climate, what is the 'best' method of archiving these? Spinny magnets? Solid state drives? USB? Tape? Blu-ray? All have pros and cons and price considerations. If I remove the price issue (my data is important to me), does this change the choice?"

AmiMoJo sends in a BBC story about the hardware used to decommission a nuclear reactor: "The device cost £20m to design and build and will operate in highly radioactive conditions inside Dounreay's landmark Dome. Its detachable tool bits cost £100,000 each and weigh between 37-93kg. They will cut and grab 977 metal rods once used to 'breed' plutonium from uranium. ... Once in place, the device will operate in highly radioactive conditions and in a nitrogen atmosphere. Nitrogen prevents any residue of the liquid metal from reacting. Exposure to water or oxygen would cause the metal to catch fire. ... Up to three tool bits will be in use at any one time and can be replaced by another three carried in a special tool box without the need to remove the tool itself from the reactor. The rest of the tool bits will be stored above the reactor and would be fitted into place during service and maintenance breaks."

thecarchik writes "Consider yesterday's collapse of electric car company Green Vehicles an object lesson in why it's a bad idea for cities to invest in the risky business of start-up car companies — perhaps especially start-up electric car companies. Even such companies with a viable product have seen their fair share of financial troubles, but Green Vehicles did not even have a product to sell off at a fire sale. The city of Salinas, California learned that lesson as Green Vehicles shut its doors, costing the city more than $500,000."

An anonymous reader writes "Dumpster Drive is a file-sharing application that recycles digital files. Using dumpster diving as a model for recirculating unwanted objects, Dumpster Drive allows others to dig through files that you delete on your computer in a passive file-sharing network. Instead of simply erasing data from your computer, the software allows users to extend the lifecycle of their unwanted files and pass them on to others." Not sure how useful this is, but I think it's a neat idea.

tripleevenfall sent in a link with a story that is sure to be the basis for the next iPhone 4 commercial. From the article: "Jarrod McKinney's iPhone 4 — a notoriously fragile device — cracked when his 2-year-old knocked it off a bathroom shelf. So it's easy to see why McKinney, a 37-year-old in Minnesota, would be 'just absolutely shocked' when that same phone survived a fall from his pocket — while he was skydiving from 13,500 feet."

snydeq writes "InfoWorld's Serdar Yegulalp provides an in-depth tutorial on how he rooted and upgraded his Motorola Cliq XT, one of many Android phones made infamous for not receiving further Android updates beyond 1.5. 'It turned out to be quite an odyssey, with twists and turns I describe here in order to help those who wish to embark on a similar journey,' Yegulalp writes. 'Was it worth the trouble? Yes, in the sense that learning how to jailbreak your own phone is a valuable skill, and I got much more functionality out of the Cliq, when I was expecting to simply junk it. '"

twoheadedboy writes "Las Vegas data centres are just as opulent as the casinos which litter the vibrant city. SuperNAP is the biggest in all Las Vegas, with 400,000 square feet of servers using around 100 megawatts of power. There's some serious security too, comprised mostly of ex-US Marines who patrol the perimeter on foot and in Humvees, all armed with assault rifles. Private military contractors are needed in the IT world too, it seems. IT Pro got a look around this impressive DC."

An anonymous reader writes "By combining a dexterous robotic arm, a foam-padded lightsaber, the movement tracking capabilities of Microsoft's Kinect sensor, and some clever software, students at Stanford University have created what can only be called a JediBot. Using a series of pre-programmed 'attack moves', and Kinect to detect the location of the enemy's light saber, JediBot can attack and defend with surprising grace. For now its attack moves are fairly slow — it can only attack once every 2 or 3 seconds — but presumably you could tweak a knob (and remove the foam padding) to turn JediBot into a real killing machine." I look forward to model that can also "force choke" an opponent.

An anonymous reader writes "Georgia Tech's Healthcare Robotics Lab and Willow Garage have been collaborating with Henry Evans, who became a mute quadriplegic after suffering a stroke 10 years ago, to use a PR2 robot as his surrogate. The robot is allowing him to do things like shave himself and scratch itches when he has them, things for which he's been dependent on other people. Henry uses a head tracker to directly move the robot's body, including its arms and head, or invoke autonomous actions, such as navigating in a room or fetching objects. The researchers hope personal robots will allow people with severe physical disabilities to live better and gain more independence."

thebchuckster writes "A Japanese developer has released a cool, new sphere that is billed as being able to go where humans can't. The sphere is 17-inches, features eight movable rudders, and can hover in the air for at least eight minutes. While reaching speeds of up to 37 miles per hour, the sphere deftly moves through the air without much effort. It doesn't take much to get it up in the air and moving, and it will be adept at going into tight areas."

danomac writes "Apple is testing out new chip suppliers, trying to find a supplier other than Samsung. Apple is currently suing Android phone manufacturers, and Samsung is included in the lawsuit. 'Apple faces several hurdles should it want to make a switch to TSMC, including patents and chip design issues as well as a push by Samsung to retain the business. ... Analysts and other sources had previously said TSMC, the world's largest contract chip maker, was set to become a supplier of a next-generation processor chip to Apple, likely starting next year. However the chip may not be called the A6, as some reports have indicated, the sources said. TSMC is an obvious candidate to win processor business from Apple as it has budgeted $7.8 billion this year to update technology and add capacity. It also has experience with the architecture of British chip designer ARM Holdings Plc, widely used by Apple to make power-efficient mobile chips."
