Submission + - federal judge sentences woman to three years for s (

derGoldstein writes: From AllThingsD: "Today a federal judge in Florida sentenced a woman to three years in prison and fined her $166,000 for selling counterfeit chips around the world to more than 1,000 buyers, among them companies selling equipment to the U.S. Navy. It’s being described as the first federal sentence for selling counterfeit chips. ... She was charged alongside Shannon L. Wren, now deceased, and together, they were accused of running a company called VisionTech... The DOJ says that on more than 35 separate occasions, they sold some 59,540 chips worth about $425,000. When customers who bought them complained that the chips were fakes — they didn’t work — McCloskey and Wren took no action."

Submission + - Jet-Powered ATV (

derGoldstein writes: "PopSci photographer John Carnett stripped a Polaris RZR and rebuilt it with a mishmash of parts—and a powerful jet engine". The project took 10 months and $15,000. "Topping out at just over 60 mph, it isn’t much faster than a stock RZR, but the Whirl’s gas turbine reaches maximum power in seconds and stays at that level all the time, so it can get up to its top speed almost instantly even from a dead stop".

Submission + - Laser-Mapped Subterranean Passages (

derGoldstein writes: La Subterranea is a project that uses lasers to map out underground structures: "La Subterranea, an ongoing research project which takes its name from a tunnel and viaduct system running underneath and through the city of Guanajuato, Mexico". They have a video of the area they've mapped so far. I imagine that one could take this geometry, along with photographic data, to create a virtual representation of the tunnel system. This could be a way to extend current 3D mapping projects like the ones in Google Earth and Bing Maps to incorporate underground and indoor environments.

Submission + - Open-Source Hardware Takes Steps Toward Mainstream (

derGoldstein writes: ComputerWorld considers the viability of open-source hardware: "Could the same philosophy [of open source software] — the free and public dissemination of underlying code and specs, with multiple developers from disparate sources contributing to the design — work for tech gadgets as well? Will we one day commonly use smartphones, netbooks or other gadgets that have been developed under an open-source model, maybe even preferring them over proprietary products like the iPhone?"

Submission + - Artificial Foot Recycles Energy for Easier Walking (

derGoldstein writes: University of Michigan engineers put wasted walking energy to work enhancing the power of ankle push-off. "For amputees, what they experience when they're trying to walk normally is what I would experience if I were carrying an extra 30 pounds," said Art Kuo, professor in the University of Michigan departments of Biomedical Engineering and Mechanical Engineering. Compared with conventional prosthetic feet, the new prototype device significantly cuts the energy spent per step.
Data Storage

Submission + - IBM and Fujifilm develop 35TB tape cartridges ( 5

derGoldstein writes: IBM and FujiFilm are introducing 35TB magnetic tape cartridges. The new tape stores data at "at a density of 29.5 billion bits per square inch". Businesses and Governments still use tape media to store the majority of their data, due to reliability, high data-density, and low power consumption.

Submission + - Servers from dense arrays of low-power processors

derGoldstein writes: Slashdot has previously followed attempts to create server architectures from netbook processors, specifically the FAWN project. Now that Cortex-A8 based systems are available on SODIMM modules, will new attempts be made at creating very dense arrays of systems for application where fast, concurrent data retrieval is important — primarily web servers?
