One Step Closer To Speedier, Bootless Computers

"Physicists at the University of California at Riverside have made a breakthrough in developing a 'spin computer,' which would combine logic with nonvolatile memory, bypassing the need for computers to boot up. The advance could also lead to super-fast chips. The new transistor technology, which one lead scientist believes could become a reality in about five years, would reduce power consumption to the point where eventually computers, mobile phones and other electronic devices could remain on all the time. The breakthrough came when scientists at UC Riverside successfully injected a spinning electron into a resistor material called graphene, which is essentially a very thin layer of graphite. The graphene in this case is one-atom thick. The process is known as 'tunneling spin injection.' A lead scientist for the project said the clock speeds of chips made using tunneling spin injection would be 'thousands of times' faster than today's processors. He describes the tech as a totally new concept that 'will essentially give memory some brains.'"

Small Startup Prevails In Server Cooling 'Chill Off'

"A small startup has shown exceptional energy efficiency in a data center 'chill off' comparing server cooling technologies. Clustered Systems posted the best numbers in the 18-month vendor evaluation sponsored by the Silicon Valley Leadership Group. The Menlo Park, Calif. company built a prototype server that uses no fans and cools processors with a cold plate with tubing filled with liquid coolant. The testing accidentally highlighted the opportunity for additional energy savings, when the Clustered Systems unit continued to operate during a cooling failure that raised the chiller plant water temperature from 44 to 78 degrees F."

Cooking With Your USB Ports

"Wow, I would never have thought to try and cook food with the power that a standard USB port provides, but someone did. A standard port provides 5V of power, give or take a little. I am not even sure what it takes to heat a small hotplate, but I am sure it is more than 5V. It looks like the guy tied together around 30 USB cables powered by his PC to power this small hotplate. But believe it or not, it seems to have cooked the meat perfectly."

AOL Spends $1M On Solid State Memory SAN

"AOL recently completed the roll out of a 50TB SAN made entirely of NAND flash in order to address performance issues with its relational database. While the flash memory fixed the problem, it didn't come cheap, at about four times the cost of a typical Fibre Channel disk array with the same capacity, and it performs at about 250,000 IOPS. One reason the flash SAN is so fast is that it doesn't use a SAS or PCIe backbone, but instead has a proprietary interface that offers up 5 to 6Gb/s throughput. AOL's senior operations architect said the SAN cost about $20 per gigabyte of capacity, or about $1 million. But, as he puts it, 'It's very easy to fall in love with this stuff once you're on it.'"

A quick look at the Windows Phone 7 demo

Yesterday, Steve Ballmer took the stage to orchestrate the introduction of his company's long-awaited revamp of its phone operating system. We've picked up a few review units, but aren't able to talk about them at the moment, so we thought we'd share some of our photos of the event to hold you over until the reviews are ready. Some of them reveal a bit about the Windows Phone 7 interface.

Intel's upgradable processor: good sense or utter catastrophe?

Intel's upgradable processor: good sense or utter catastrophe?
Intel is about to experiment with a new concept in mass-market processors with its forthcoming Pentium G6951 CPU: upgradability. The chips will be upgradable by end users via a purchased code that is punched in to a special program. Previews of the processor quietly hit the Web last month, and with Engadget's post of the retail packaging, people took notice with reactions ranging from surprise to outright disgust.
The Pentium G6951 is a low-end processor. Dual core, 2.8GHz, 3 MB cache, and expected to be around $90 each when bought in bulk—identical to the already-shipping Pentium G6950. The special part is the software unlock. Buy an unlock code for around $50, run the software downloaded from Intel's site, and your processor will get two new features: hyperthreading will be enabled, and another 1 MB of cache will be unlocked, giving the chip a specification just short of Intel's lowest Core i3-branded processor, the 2.93 GHz Core i3-530. Once unlocked, the G6951 becomes a G6952.( More … )

Probabilistic processors possibly pack potent punch

Probabilistic processors possibly pack potent punch
A DARPA-funded processor start-up has made bold claims about a new kind of processor that computes using probabilities, rather than the traditional ones and zeroes of conventional processors. Lyric Semiconductor, an MIT spin-off, claims that its probabilistic processors could speed up some kinds of computation by a factor of a thousand, allowing racks of servers to be replaced with small processing appliances.
Calculations involving probabilities have a wide range of applications. Many spam filters, for example, work on the basis of probability; if an e-mail contains the word "Viagra" it's more likely to be spam than one which doesn't, and with enough of these likely-to-be-spam words, the filter can flag the mail as being spam with a high degree of confidence. Probabilities are represented as numbers between 0, impossible, and 1, certain. A fair coin toss has a probability of 0.5 of coming up heads.( More … )

FSF Announces Hardware Endorsement Criteria

"The Free Software Foundation has announced criteria for the hardware endorsement program 'Respects Your Freedom.' From the announcement: 'The desire to own a computer or device and have full control over it, to know that you are not being spied on or tracked, to run any software you wish without asking permission, and to share with friends without worrying about Digital Restrictions Management (DRM) — these are the desires of millions of people who care about the future of technology and our society. (...) With our endorsement mark and the strong criteria that back it, we plan to bridge that gap and demonstrate to manufacturers that they stand to gain plenty by making hardware that respects people's freedom instead of curtailing it.' While it currently contains some requirements that many may find broader than what they personally need, the remaining criteria would make the FSF endorsement a useful tool when looking for devices that give the owner control over the device they have bought and paid for. The criteria are still open for feedback."

Study Shows Babies Think Friendly Robots Are Sentient

"A study from University of Washington claims that babies think robots are human, so long as the robots are friendly. No word on what evil robots are thought to be. From the article: 'At 18 months old, babies have begun to make conscious delineations between sentient beings and inanimate objects. But as robots get more and more advanced, those decisions may become harder to make. What causes a baby to decide a robot is more than bits of metal? As it turns out, it takes more than humanoid looks — babies rely on social interaction to make that call.'"

Unspoofable Device Identity Using Flash Memory 


wiredmikey writes with a story from Security Week that describes a security silver lining to the inevitable errors that arise in NAND flash chips. By seeking out (or intentionally causing) defects in a given part of the chip, a unique profile can be created for any device using NAND flash which the author says may be obscured, but not reproduced: "[W]e recognize devices (or rather: their flash memory) by their defects. Very much like humans recognize faces: by their defects (or deviations from the 'norm') a bigger nose, a bit too bushy eyebrows, bigger cheeks. The nice twist is that if an attacker manages to read your device identity, he cannot inscribe it into his own device. Yes, he can create errors — like we did. But he cannot control where in the block they occur as this relies solely on microscopic manufacturing defects in the silicon."

Huge Shocker — 3D TVs Not Selling

"It comes as no surprise to the vast majority of us who haven't rushed out to buy a 3D TV, but according to a DisplaySearch report consumers aren't doing their part to make 2010 the year of 3D TV, says blogger Peter Smith. And the stats are even worse than Smith imagined they'd be: 'DisplaySearch estimates that 3.2 million 3D TVs will be shipped in 2010. Note, that's shipped, not sold. 3.2 million equates to 2% of all flat panel displays shipped (as far as I can ascertain, that's worldwide shipments). So yeah, there are not many 3D TVs being shipped this year. But wait, that's not the end of the bad news. In Western Europe (the only region where they offered this data point) sales of 3D glasses are less than 1 per 3D set sold. In other words, a lot of Western Europeans who buy a TV with 3D capability don't even bother to buy the glasses to use that feature.'"

Pirate Electrician Supplied Power To 1,500 Homes

 "A former electrical engineer for utility EDF has been prosecuted for illegally supplying power to some 1,500 homes in north London. Derek Brown, 45, was arrested in 2008 after being seen tampering with the electric grid in a manhole. He specialized in connecting separate supplies to houses that were split into apartments. One landlord involved, Haresh Parmar, was jailed for 9 months for stealing £30,000 worth of electricity for 22 of his apartments. Brown's assets will be seized and he has been sentenced to 8 months suspended, and 150 hours community service."
