Network Adapter Keeps Talking While a PC Is Asleep 188

Al writes "Researchers at Microsoft and the University of California, San Diego have developed a network adapter that lets a computer enter sleep mode without disrupting the network connection. The adapter, dubbed Somniloquy (meaning to talk in one's sleep), consists of a gumstix running embedded Linux, 64MB of RAM and a 2G SD memory card, connected via USB. The adapter keeps the network connection going and the researchers have also developed a simplified IM client and bittorrent client that carry out more complicated tasks autonomously, only waking the computer if, for example, an actualy IM is received or a download is completed."

Neural Networks-Equipped Robots Evolve the Ability To Deceive 116

pdragon04 writes "Researchers at the Ecole Polytechnique Fédérale de Lausanne in Switzerland have found that robots equipped with artificial neural networks and programmed to find 'food' eventually learned to conceal their visual signals from other robots to keep the food for themselves. The results are detailed in a PNAS study published today."

Fatal Explosion At Russian Hydroelectric Dam 336

stadium writes "An oil-filled transformer exploded at the Sayano-Shushenskaya power plant in Siberia, destroying three turbines and bringing down the ceiling of the turbine hall, which then violently flooded. The dam itself did not sustain any damage. It is unclear how many people were killed, but with 12 confirmed deaths and as many as 64 still missing (all presumed dead), this is a serious incident. The huge transformer had enough oil in it to produce a three-mile-long oil spill slowly moving downriver. BBC News reports with three separate videos. The dam produces a quarter of the total energy of RusHydro (whose stock thus took a steep dive at London Stock Exchange) and also feeds the world's largest aluminum smelter. The damages will take years to repair."

World's Only Diesel-Electric Honda Insight 687

Jake Staub writes "Just replaced the gasoline engine in a Honda Insight with a Diesel engine. On a 3,000 mile cross-country shakedown journey the car averaged 92mpg over 1,800 miles. Around a very hilly town in Northwest Washington, the car is averaging 78mpg. These mileage averages are without the electric side of the vehicle fully functional. With a bit more tinkering on the electric side and through a slight gearing change through tire size, it is anticipated that the car will likely average 100mpg. The build for the car has been documented on the web site and is as close to open source as my time allows. The car was built by two guys in a garage in Southern Maryland. If we can do it I don't see any reason why major auto manufacturers can't do it since we used their parts."

IBM Scientists Build Computer Chips From DNA 97

snydeq writes "Scientists at IBM are experimenting with using DNA molecules as a way to create tiny circuits that could form the basis of smaller, more powerful computer chips. The technique builds on work done by Cal Tech's Paul Rothemund, who found that DNA molecules can be made to 'self-assemble' into tiny forms [PDF] such as triangles, squares and stars. 'To make a chip, the scientists first create lithographic templates using traditional chip making techniques. After, they pour a DNA solution over the surface of the silicon and the tiny triangles and squares — what the scientists call DNA origami — line themselves up to the patterns etched out using lithography.' DNA-based chips may sound like crackpot tech, but those involved believe the methodology could lead to a new way of fabricating features on the surface of chips that allows semiconductors to be made even smaller, faster and more power-efficient than they are today."

New Nano-Laser Created 84

Many sources are reporting that researchers have created the world's smallest laser since the inception of lasers almost a half-century ago. Dubbed "spasers," as an acronym for "surface plasmon amplification by stimulated emission of radiation," their incredibly tiny size could become a critical component for future technologies like "nanophotonic" circuitry. "Such circuits will require a laser-light source, but current lasers can't be made small enough to integrate them into electronic chips. Now researchers have overcome this obstacle, harnessing clouds of electrons called 'surface plasmons,' instead of the photons that make up light, to create the tiny spasers."

NASA Developing Nuclear Reactor For Moon and Mars 424

Al writes "NASA recently finished testing a miniature nuclear reactor that would provide power for an astronaut base on the Moon or Mars. The reactor combines a small fission system with a Stirling engine to make a 'safe, reliable, and efficient' way to produce electricity. The system being tested at NASA's Glenn Research Center can produce 2.3 kilowatts and could be ready for launch by 2020, NASA officials say. The reactor ought to provide much more power than solar panels but could prove controversial with the public concerned about launching a nuclear power source and placing it on the Moon or another planet."

An Electricity-Cost-Aware Internet Routing Scheme 88

Al writes "Researchers from MIT, Carnegie Mellon and Akamai have developed a network-routing scheme that could save 'internet-scale' companies such as Google, Amazon and Microsoft million of dollars each year by moving data to locations with the best electricity prices for a particular day. The scheme simply considers both the most efficient routing path for data and the potential cost savings of routing it somewhere farther away. The researchers studied price fluctuations at locations across the country and used data from Akamai caching servers to test the idea out. In the best possible scenario — which would require more efficient servers — they estimate that companies could save as much as 40% on the electricity bills (tens of millions each year). Google already operates at least one datacenter that shuts down when temperatures get too high. Is this the next logical step for internet computing?"

Arizona Judge Tells Sheriff "Reveal Password Or Face Contempt" 624

An anonymous reader writes "Four days ago, deputies from the Maricopa County Sheriff's Office in Arizona conducted a raid against the county government building hosting computers for a law enforcement database. After threatening to arrest county employees who would stop them, the officers proceeded to secure the room and promptly changed passwords on many of the servers. In a hearing on Friday, a Superior Court judge threatened to hold members of the Sheriff's Office in contempt if they did not reveal the passwords by next Wednesday. Following this, the Sheriff's Office claimed to be conducting an investigation against other Superior Court judges. Courts have asked for passwords before, but never under conditions like this."

Dell Considering ARM-Based Smartbooks 298

wonkavader sends us this quote from an article in PCWorld: "In an effort to expand its Linux offerings, Dell is researching new netbook-type devices and will soon offer netbook Linux OS upgrades, a company official said on Wednesday. The company is researching the possibility of offering new Linux-based mobile devices called smartbooks, said Todd Finch, senior product marketing manager for Linux clients, at the OpenSourceWorld conference in San Francisco. The company will also upgrade its Ubuntu Linux OS for netbooks to the latest version in the next few weeks ... Smartbooks with Arm chips have inherent advantages over x86 chips like Atom, such as lower power consumption and longer battery life, according to Finch. The chips are also becoming more powerful, as indicated by the growing number of applications on smartphones, he said. 'I think it's natural and reasonable for us to begin looking at them as they begin scaling their processors up.'"

Building an Apple-1 From Scratch — Just Like Woz 99

Lucas123 writes "This year at KansasFest, computer fans from around the world gathered to celebrate the Apple II — the computer that put Apple on the map. But the Apple-1 (a.k.a. the Apple I), the machine Steve Wozniak invented and first demonstrated at the Palo Alto Homebrew Computer Club in 1976, has always been near to my heart. In attendance at KansasFest was Vince Briel, who created an authorized reproduction the Apple-1 and showed others how to build their own. 'As a regular KansasFest attendee (and the conference's marketing director), I was one of his students. Follow along as I assemble a fully functional Apple-1 clone.'"

Dell Says High Linux Netbook Returns a "Non-Issue" 324

Michiel Roos notes that at this week's OpenSource World, a Dell executive deflated Microsoft's claims that Linux notebooks have return rates four or five times higher than Windows machines. "Todd Finch, Dell senior product marketing manager, said the number of Linux returns are approximately the same as those for Windows netbooks. He categorized the matter of returns as a 'non-issue.' 'They are making something of nothing,' he said of Microsoft's claims."

Mixed Conclusions About Powerline Networking vs. Ham Radio 343

Barence writes "Since writing about the success he's had with powerline networking, a number of readers emailed PC Pro's Paul Ockendon to castigate him for recommending these products, such as HomePlug. They were all amateur radio enthusiasts, claiming the products affect their hobby in much the same way that urban lighting affects amateur astronomers, but rather than causing light pollution they claim powerline networking causes radio pollution in the HF band (otherwise known as shortwave). Paul's follow-up feature, 'Does powerline networking nuke radio hams?' documents his investigation into these claims, which found evidence to support both sides of an intriguing debate."

Will Silicon Valley Run Out of Data Center Space? 142

1sockchuck writes "With capital scarce, data center developers are prioritizing projects in northern Virginia, where the Obama stimulus plan and federal shift to cloud computing are likely to boost data center demand from government agencies. This is forcing them to delay or scale back large projects in Santa Clara, setting the stage for a supply/demand imbalance in Silicon Valley, particularly for large space requirements. One potential mitigating factor: some currently occupied data center space could become available through the failure of venture-backed startups."

HP Restores Creased Photos With Flatbed Scanners 125

An anonymous reader writes "Scientists at HP have developed a technique to detect creases in photographs using standard, unmodified flatbed scanners. Once correctly scanned into a computer, software can determine where the photograph's defect is, and artificially correct it to remove any trace of a crease or fold. The result is a spotless JPEG scan from a creased photo, with absolutely no modified hardware and no technical know-how required on the part of the user." They're using multiple light sources to do this, in a way that reminds me of last year's description of 3D image creation using an ordinary digital camera.

How Artificial Leaves Could Generate Clean Hydrogen 101

An anonymous reader writes "At Imperial College London, researchers have embarked on a £1m project to study, and eventually mimic, photosynthesis. Part of the 'artificial leaf' project involves working out exactly how leaves use sunlight to make useful molecules. The team then plans to build artificial systems that can do the same to generate clean fuels such as hydrogen and methanol. These would then be used in fuel cells to make electricity or to directly power super-clean vehicles."

Intel Licenses NVIDIA SLI Technology For P55 Chips 63

adeelarshad82 writes "NVIDIA announced that Intel has licensed the company's SLI technology for inclusion in upcoming products — as have a slew of major hardware partners such as ASUS, EVGA, Gigabyte, and MSI. This means the P55 chipsets that power those new socket LGA 1156 motherboards, which are based around the next-gen Nehalem architecture, will let you build systems using two or four NVIDIA-powered GPUs. Specifically, the licensing agreement covers the Core i5 and Core i7 microprocessors."

Chevy Volt Rated At 230 mpg In the City 1006

necro81 writes "General Motors, emerging from bankruptcy, today announced that its upcoming plug-in hybrid vehicle, the Volt, will have an EPA rating of 230 mpg for city driving (about 98 km/L). The unprecedented rating, the first in triple digits, is the result of a new (draft) methodology for calculating the 'gas' mileage for vehicles that operate primarily or extensively on electricity. The Volt, due out late next year, can drive approximately 40 miles on its Li-Ion battery pack, after which a gasoline engine kicks in to provide additional electricity to charge the battery. Running off the gasoline engine yields approximately 50 mpg. Of course, the devil's in the details, because the conversion of grid-based electricity to gasoline-mileage is imprecise." Now we know the meaning of the mysterious "230" viral marketing campaign.

"Terminator Vision" Is Here For the iPhone 245

musefrog writes "The BBC is reporting that so-called augmented reality has arrived — in the UK at least. From the article: 'Via the video function of a mobile phone's camera it is now possible to combine a regular pictorial view with added data from the internet just as the fictional Terminator was able to overlay its view of the world with vital information about its surroundings. For example, UK-firm Acrossair has launched an application for the iPhone which allows Londoners to find their nearest tube station using their iPhone.' The page features an impressive video demonstrating AR in action."
