Coating a Motherboard In Thermal Resin? 272

Bat Country writes "I've had an idea in the back of my head for some time (and I'm surely not the only one) that it would be a worthwhile project to coat a motherboard in thermally conductive electrically insulating resin — complete with all of its various components — for the purpose of immersion, shock resistance, whatever. I'm curious to find out if anyone's undertaken a similar project or if it's known to be a shockingly bad idea (due to shrinkage during the curing process) already. Thoughts?" If you've done anything similar (even an experiment that failed), how did you go about it?

Journal Journal: Microsoft to Provide Users with TUX

In this ZDNet interview with Scott Charney, head of trustworthy computing at Microsoft, admitted this week that Windows Vista's User Account Control prompts are not intuitive and confuse users.

Interestingly, during the interview, Scott mentions the goal of providing users with TUX, or trusted user experience.

Will Motorola Rise From the Ashes? 128

An anonymous reader writes "According to ZDNET the once almighty Motorola is going to split into two companies, 'If the split goes through as planned, what will remain will be the "broadband and mobility solutions" business, which includes enterprise mobility, government and public safety, and Motorola's home and networks divisions.' Engadget claims to have an insider's email that details where it all went wrong, paying particular attention to mismanagement at the highest levels. What makes all of this even more of a shame though is that Motorola's latest product lineup seems to be receiving critical acclaim but with the company in so much termoil, will it ever rise out of the ashes?"

Defunct Spy Satellite Falling From Orbit 312

dnormant, among other readers, sent us word that a US spy satellite has lost power and propulsion and could hit the Earth in late February or March. Government officials spoke on condition of anonymity because the information is classified as secret. None of the coverage speculates on how big the satellite is, but Wikipedia claims that US spy satellites in the KH-11 class, launched up to the mid-90s, are about the size of the Hubble — which is 13 meters long and weighs over 11,000 kg. "The satellite, which no longer can be controlled, could contain hazardous materials, and it is unknown where on the planet it might come down... A senior government official said that lawmakers and other nations are being kept apprised of the situation."

Cell Phone Radiation Detectors Proposed to Protect Against Nukes 238

crosshatch brings us news out of Purdue University, where researchers are developing a radiation detection system that would rely on sensors within cell phones to locate and track potentially hazardous material. From the Purdue news service: "Such a system could blanket the nation with millions of cell phones equipped with radiation sensors able to detect even light residues of radioactive material. Because cell phones already contain global positioning locators, the network of phones would serve as a tracking system, said physics professor Ephraim Fischbach. 'The sensors don't really perform the detection task individually,' Fischbach said. 'The collective action of the sensors, combined with the software analysis, detects the source. Say a car is transporting radioactive material for a bomb, and that car is driving down Meridian Street in Indianapolis or Fifth Avenue in New York. As the car passes people, their cell phones individually would send signals to a command center, allowing authorities to track the source.'"

Molten Salt-Based Solar Power Plant 478

rcastro0 writes "Hamilton Sundstrand, a division of United Technologies, announced today that it will start to commercialize a new type of solar power plant. A new company called SolarReserve will be created to provide heat-resistant pumps and other equipment, as well as the expertise in handling and storing salt that has been heated to more than 1,050 degrees Fahrenheit. According to venture capitalist Vinod Khosla 'Three percent of the land area of Morocco could support all of the electricity for Western Europe.' Molten Salt storage is already used in Nevada's Solar One power plant. Is this the post-hydrocarbon world finally knocking?"

Tiny, Morphing, Electricity-Stealing Spy Planes Developed 163

tkohler writes "The Air Force Research Lab is developing an Electric Motor-powered Micro Air Vehicle (MAV) that can 'harvest' energy when needed by attaching itself to a power line. It can also temporarily change its shape to look more like innocuous piece of trash hanging from the cable. For domestic spying, maybe it will morph into a pair of sneakers?"

Submission + - Nanowires boost laptop battery life to 20 hours

brianmed writes: Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, cell phones, MP3 players and other portable devices. The new version, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces up to 10 times the amount of electricity of existing lithium-ion batteries.

Submission + - OLPC XO Review (bioslevel.com) 1

BIOS_LEVEL writes: "The XO is the laptop produced by the One Laptop Per Child program (OLPC) headed by Mr. Nicholas Negroponte. The goal of OLPC is to provide every child a laptop which they can use to experience technology and the Internet. Through the Give One Get One program (G1G1), residents of North America are able donate $400 to the OLPC foundation, $200 of which finances a laptop for a child, and $200 of which pays for the cost of delivering one to the donor. Colin Dean was one of the first to participate in G1G1, and this is his review of it."

Microsoft Disses Windows to Sell More Windows 407

mjasay writes "I stumbled across this fascinating Microsoft tutorial entitled "How to Justify a Desktop Upgrade." It's an attempt to coach IT professionals on how to sell Windows desktop upgrades internally. Apparently the value of Vista is not readily apparent, requiring detailed instructions on how to connive and cajole into an upgrade from XP. The most intriguing thing about the tutorial is its implicit rejection of Microsoft's older technology. Just a few years ago Microsoft was pitching the world on how secure and cool XP was. Now it's telling us largely the opposite, implying that XP is a security threat, costs too much to run, and so on. With Microsoft marketing against itself, perhaps the Mac and Linux camps can simply wait for Microsoft to self-destruct?"
