Mike writes "Here's a brilliant idea for biofuels: rather than filtering used fry oil for use in vehicles, why not simplify matters and use it to heat and power the restaurant itself? The VegaWatt turns used vegetable oil into clean heat and energy for restaurants, eliminating the dirty and costly mess of oil disposal while producing 10-25% of the electricity needed to run a small restaurant. It also produces fuel free of chemicals or fossil fuels, unlike standard biodiesel."

CWmike writes "Microsoft has ramped up its new Windows support assistant 'Fix it for me' nearly three months after it quietly released the automatic repair and configuration tool. The upgrade adds a 'Fix it' button to some of the support documents that Microsoft posts to its Knowledge Base. The blog introducing the changes lists some of the Knowledge Base documents that boast the 'Fix it' button, including one that prevents users from connecting a USB storage device — useful in protecting against one of the infection vectors of the 'Downadup' worm. Have ideas for the tool? In a forum on the 'WinVistaClub' Web site, someone who said he was part of the 'Fix it' team at Microsoft encouraged users to send feedback on the feature to the group at fixit4me@microsoft.com."

JasonDT writes "I just accepted the new terms of service for iTunes and found that I will no longer be allowed to access US iTunes outside of the United States. This may seem like no big deal but, I am a US citizen living abroad and I regularly purchase and view TV and movies from AppleTV. Not to mention US citizens just traveling abroad. Does anyone know if this has been enforced or have themselves been affected by this?"

"Inventor Ted Ciamillo and marine biologist Frank Fish (yes, that's his real name) are at work on a human-powered sub designed to cross the Atlantic. What's interesting is the highly efficient propulsion system which uses a 'tail' modeled after CAT scans of a dolphin's. From the article: 'Ciamillo and Fish say they knew they were onto something when the first prototype Lunocet, a piece of sculpted foam sandwiched between two pieces of carbon fiber, essentially swam by itself. When they released it at the bottom of a test pool, its buoyancy combined with its cambered shape generated a forward thrust that made it scoot across the tank.'"

mcgrew writes "New Scientist reports that a British team has overcome the obstacles to cheap LED lighting, and that LED lamps as cheap as CFLs will be on the market in five years. Quoting: 'Gallium nitride cannot be grown on silicon like other solid-state electronic components because it shrinks at twice the rate of silicon as it cools. Crystals of GaN must be grown at 1000C, so by the time a new LED made on silicon has cooled, it has already cracked, rendering the devices unusable. One solution is to grow the LEDs on sapphire, which shrinks and cools at much the same rate as GaN. But the expense is too great to be commercially competitive. Now Colin Humphreys's team at the University of Cambridge has discovered a simple solution to the shrinkage problem. They included layers of aluminium gallium nitride in their LED design... These LEDs can be grown on silicon as so many other electronics components are. ... A 15-centimetre silicon wafer costs just $15 and can accommodate 150,000 LEDs making the cost per unit tiny.'"

Through the Remix API, Best Buy can track how many people are using its information, while users can check to see where a certain product is available without visiting Best Buy's site. Web developers and bloggers can also sign up to become an official Best Buy affiliate. If approved, they can get a small percentage of a sale if someone makes a Best Buy purchase through their site."

Ian Lamont sends along a brief note from the Industry Standard about "intelligent" pills that can help doctors record information about drug dosages, heart rate, respiratory rate, and other metrics. The pills, being developed by Proteus Biomedicals, have "digestible sensors" made out of food products and are activated by stomach fluids. A receiver that is similar to a skin patch picks up the data and can be passed on to a 3G mobile network, and from there to hospitals or doctors' offices. According to the Proteus site, the sensors cost a few cents per pill. The devices, currently in clinical trials, made #8 on Wired's list of the top technology breakthroughs of 2008.

danboid writes "I'm an IT technician at a large school near Manchester, England. We currently have two separate networks (one for pupils, one for staff) each with its own Windows Server 2003 Active Directory box handling authentication and storing users' files. We're planning on restructuring the network soon and we'd like to be able to replace the two aging AD servers with a single, more powerful Linux server running an open source OpenLDAP implementation. The main contenders for this purpose seem to be Fedora Directory Server, OpenDS, and Apache Directory Server; but I've been unable to find meaningful comparisons among the three. I'd like to hear which solution Slashdot readers recommend. What is your experience with ease of implementation / maintenance? Any stories of similar (un)successful migrations? Any other tips for an organization wanting to drop AD for a FOSS equivalent?"

Hugh Pickens writes "The San Fransisco Chronicle is running a story about Brian Malow, a stand-up comedian who has showcased his science-centric stand-up humor for more than a decade in comedy clubs, at conventions and for corporate clients across the country. Fortunately, club patrons don't need a degree in quantum mechanics to appreciate one-liners like 'I used to be an astronomer, but I got stuck on the day shift,' 'I just started reading, "The Origin of Species." Don't tell me how it ends!' or that he 'attended a magnet school for bipolar students.' While his show is very rational and based on hard science, Malow cleverly infuses it with an abstract or surreal comic twist."
