8-Core Intel Nehalem-EX To Launch This Month 186

Posted by Soulskill from the double-the-cores-for-only-twice-the-price dept.
MojoKid writes "What could you do with 8 physical cores of CPU processing power? Intel's upcoming 8-core Nehalem-EX is launching later this month, according to Intel Xeon Platform Director Shannon Poulin. The announcement puts to rest rumors that the 8-core part might be delayed, and makes good on a promise Intel made last year when the chip maker said it would release the chip in the first half of 2010. To quickly recap, Nehalem-EX boasts an extensive feature-set, including up to 8 cores per processor, up to 16 threads per processor with Intel Hyper-threading, scalability up to eight sockets via Intel's serial Quick Path Interconnect and more with third-party node controllers, and 24MB of shared cache."

Disposable Toilet To Change the World Screenshot-sm 413

Posted by samzenpus from the sunshine-in-a-bag dept.
captn ecks writes "A biodegradable and self-sterilizing bag for people of the toilet-disenfranchised world (40% of humankind) to dispose of their bodily waste and turn it into safe fertilizer has been created by a Swedish entrepreneur. It's a dead simple and brilliant solution to a vexing problem. From the article: 'Once used, the bag can be knotted and buried, and a layer of urea crystals breaks down the waste into fertilizer, killing off disease-producing pathogens found in feces. The bag, called the Peepoo, is the brainchild of Anders Wilhelmson, an architect and professor in Stockholm. “Not only is it sanitary,” said Mr. Wilhelmson, who has patented the bag, “they can reuse this to grow crops.”'"

MIT Produces Electricity Using Thermopower Waves 157

Posted by Soulskill from the set-on-fire-to-begin-current-flow dept.
MikeChino writes "MIT scientists have discovered a never-before-known phenomenon wherein carbon nanotubes can be used to harness energy from 'thermopower waves.' To do this they coated the nanotubes with a reactive fuel and then lit one end, causing a fast-moving thermal wave to speed down the length of the tube. The heat from the fuel rises to a temperature of 3,000 kelvins, and can speed along the tube 10,000 times faster than the normal spread of this chemical reaction. The heat also pushes electrons down the tube, which creates a substantial electrical current. The system can output energy (in proportion to its weight) about 100x greater than an equivalent weight lithium-ion battery, and according to MIT the discovery 'opens up a new area of energy research, which is rare.'"

Microsoft "Courier" Pictures 230

Posted by ScuttleMonkey from the bandwagon-or-shark-jumping dept.
tekgoblin writes to let us know that Gizmodo has some early shots of the new prototype "Courier" booklet (foldable tablet) on the way from Microsoft. "Courier is a real device, and we've heard that it's in the 'late prototype' stage of development. It's not a tablet, it's a booklet. The dual 7-inch (or so) screens are multitouch, and designed for writing, flicking and drawing with a stylus, in addition to fingers. They're connected by a hinge that holds a single iPhone-esque home button. Statuses, like wireless signal and battery life, are displayed along the rim of one of the screens. On the back cover is a camera, and it might charge through an inductive pad, like the Palm Touchstone charging dock for Pre."

Dead Pigs Used To Investigate Ocean's "Dead Zones" 106

Posted by samzenpus from the big-ocean-long-pig dept.
timothy writes "As places to study what happens to corpses, the Atlantic Ocean is both much larger and much more specialized than the famous 'body farm' in Knoxville, TN. But for all kinds of good reasons, sending human bodies into Davy Jones' locker just to see where they float and how they bloat is unpopular. Pigs don't pay taxes, and more importantly, they don't vote. So Canadian scientists have taken to using them as human-body proxies, to study what happens when creatures of similar size and hairlessness (aka, us) end up 86ed and in the drink."

Using Classical Music As a Form of Social Control Screenshot-sm 721

Posted by samzenpus from the feeling-of-dread-in-f-minor dept.
cyberfringe writes "Classical music is being used increasingly in Great Britain as a tool for social control and a deterrent to bad behavior. One school district subjects badly behaving children to hours of Mozart in special detention. Unsurprisingly, some of these youth now find classical music unbearable. Recorded classical music is blared through speakers at bus stops, outside stores, train stations and elsewhere to drive away loitering youth. Apparently it works. Detentions are down, graffiti is reduced, and naughty youth flee because they find classical music repugnant."

Researchers Convert Mouth Movements Into Speech 154

Posted by samzenpus from the mouthing-of-the-future dept.
andylim writes "According to Cellular News, researchers at Germany's Karlsruhe Institute of Technology have developed a method for mobile phones to convert silent mouth movements into speech. As recombu.com points out, the 'potential for secret conversations just got huge.' You could pass the time by making phone calls from the cinema without disturbing anyone. In noisy places like bars and clubs you could make yourself heard without having to shout."

Privacy With a 4096 Bit RSA Key — Offline, On Paper 232

Posted by timothy from the you'll-need-a-bigger-id-badge dept.
HavanaF writes "Online backup is practical, but can it offer any privacy? The Dutch security company Safeberg developed an Offline Private Key Protocol, with an asymmetric key scheme. The protocol demands that the private (decryption) key be stored away from the 'source' computer, which presumably is 'too vulnerable.' The catch is that the private key needs to be fairly large to be secure: a 4,096-bit RSA key should suffice for some years. But how to store an 800-character key offline? Safeberg introduces a machine readable paper key, with the 4k-bit key crammed in a giant 2D Datamatrix barcode. This video on key strength tells the story."

North Korea's Own OS, Red Star 316

Posted by timothy from the linux-is-sometimes-for-communists dept.
klaasb writes "North Korea's self-developed computer operating system, named 'Red Star,' was brought to light for the first time by a Russian satellite broadcaster yesterday. North Korea's top IT experts began developing the Red Star in 2006, but its composition and operation mechanisms were unknown until the internet version of the Russia Today TV program featured the system, citing the blog of a Russian student who goes to the Kim Il-sung University in Pyongyang."

Freescale's Cheap Chip Could Mean Sub-$99 E-Readers 158

Posted by timothy from the readership-growth dept.
eldavojohn writes "Last week, Freescale Semiconductor announced their i.MX508 chip and a few days ago released a rather bland and boring announcement that it's available. But there was at least one interesting line from that press release, 'The i.MX508 applications processor is expected to be priced at less than $10 (USD) in quantities greater than 250K units.' Yes, less than ten dollars. This sparked a wave of articles detailing how this new chip will allow the sub-$99 e-reader to emerge and according to market research, consumers are thirsty for something much more affordable than the Kindle."

Consider a small freighter, 200 km off New York. It launches a few hundred small unmanned planes, guided by a small computer autopilot. Each plane carries four thermite stick bombs, similar to the ones used in WWII. When the planes reach the vicinity of New York they climb to a few hundred meters altitude and start dropping the thermite devices. What was cutting edge tech 70 years ago is garage tech today.

"Finally, the state of Western medicine in EU, CA, and UK, is largely subsidized by the fact that they can license procedures and drugs from the US. In fact, the US is effectively subsidizing our socialist brothers abroad. And we don't mind so much... but we'd prefer it if you wouldn't badmouth us while we do it." Yeah, free trade is a bitch.
