Science: New Map From Fermi Gamma-Ray Space Telescope
I Don't Believe in Imaginary Property writes "NASA has received interesting results from the Fermi Gamma-ray Space Telescope, originally known as GLAST, which has allowed them to create new map of the gamma-ray sky. The secret to its ability to resolve gamma-rays is that they use layers of tungsten interleaved with silicon detectors. When a gamma-ray strikes tungsten, it produces an electron/positron pair due to the photoelectric effect, which cascades as it goes through further layers of tungsten. Meanwhile, they record which silicon detectors had electrons or positrons pass through them to determine the direction of the source and they also record the total energy of the electron/positron pairs to calculate the wavelength of the gamma-ray using Planck's Law. The data gathered in just its first few hours of operation is reportedly comparable to the data from the Energetic Gamma-Ray Experiment Telescope, which gathered data for nine years back in the 1990's and there are hopes that it could detect dark matter in the form of weakly interacting massive particles (WIMPs)."

DesScorp writes "The Times reports on the problems of adding wind farms to the power grid. Because of the grid's old design, it can't handle the various spikes that wind farms sometimes have, and there's no efficient way to currently move massive amounts of that power from one section of the country to the other. Further complicating things is the fact that under current laws, power grid regulation is a state matter, and the Federal government has comparatively little authority over it right now. Critics are calling for federal authority over the grid, and massive new construction of "superhighways" to share the wind power wealth nationally. Quoting the article, 'The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.'"
Ask Slashdot: Digital Storage To Survive a 25-Year Dirt Nap?
AlHunt writes "I've been tasked with finding a way to bury digitally stored photographs in a small underground time capsule to be opened in 25 years. It looks like we'll be using a steel vessel, welded closed. I've thought of CDs, DVDs, a hard drive, or a thumb drive — but they all have drawbacks, not the least of which is outdated technology 25 years from now. Maybe I'll put a CD and a CD-ROM drive in the capsule and hope that the IDE interface is still around in 25 years? Ideas and feedback will be appreciated."
Apple: Andy Hertzfeld Shares His Thoughts on 25 Years of the Mac
Blackbearnh writes "It may make you feel very, very old, but the Macintosh will be turning 25 in January. As we approach this momentous anniversary, O'Reilly News had a talk with Andy Hertzfeld, one of the original Macintosh designers, about the long and storied history of the Mac. Hertzfeld, who tells the story of the Mac in his book A Revolution in the Valley, shares his thoughts about how the Mac has aged over time, how life might have been different if Steve Jobs had stayed on at Apple, and the differences between working for Apple, and for Google (his current employer.)" Read on below for a bit of what Hertzfeld had to say.
Hardware: Full Immersion Cooling Comes To Desktop PCs
Mr_sifter writes "After three years of research and around £100,000 of R&D costs, UK-based Armari has unveiled its XCP prototype. It's a full immersion liquid cooled PC which supports standard ATX components. Unlike conventional liquid cooled PCs, the components are all easy to swap in and out as they're swimming in liquid, rather than under waterblocks. It also looks amazing, pumping around 70KG of electrically inert cooling fluid (salvaged from an old Cray) around its military grade perspex shell."
Tech: Mozilla Labs' "Ubiquity" Helps Automate Web Interactions
Martin writes "Mozilla Labs have released a prototype version of the Firefox add-on Ubiquity. It is basically Launchy (the application launcher) for Firefox with the difference that Ubiquity makes use of web APIs and the Firefox browser. The official website contains examples, a command list, information about creating your own commands and of course the Ubiquity extension that is compatible with Firefox 3.x. Ubiquity can pull and send data to various services like Twitter, display, find and embed Google Maps, perform searches, write emails, add entries to the calendar, digg stories and more."
The Economist is running a story about how gaming is on the rise in corporate environments, and how games are also becoming a popular tool for advertising. From internally developed games to commercial offerings to simply creating a framework in which employees can interact, game-based competitions and community building are leading to increased productivity, even for Fortune 500 companies. Quoting: "Take Microsoft's own experience. Before it releases a new version of its Windows operating system, it asks staff to help debug the software by installing and running the system. In the past, project managers had to spend a great deal of time and effort persuading busy Microsoftees to help them with this boring task. So for Windows Vista, the system's latest incarnation, Microsoft created a game that awarded points for bug-testing and prizes such as wristbands for achieving certain goals. Participation quadrupled."
Tech: Capturing 3D Surfaces Simply With a Flash Camera
MojoKid writes with this excerpt from Hot Hardware (linking to a video demonstration): "Creating 3D maps and worlds can be extremely labor intensive and time consuming. Also, the final result might not be all that accurate or realistic. A new technique developed by scientists at The University of Manchester's School of Computer Science and Dolby Canada, however, might make capturing depth and textures for 3D surfaces as simple as shooting two pictures with a digital camera — one with flash and one without. First an image of a surface is captured without flash. The problem is that the different colors of a surface also reflect light differently, making it difficult to determine if the brightness difference is a function of depth or color. By taking a second photo with flash, however, the accurate colors of all visible portions of the surface can be captured. The two captured images essentially become a reflectance map (albedo) and a depth map (height field)."
Ben Rothke writes "Zero Day Threat: the Shocking Truth of How Banks and Credit Bureaus Help Cyber Crooks Steal Your Money and Identity is an interesting and eye-opening look at how banks and credit card companies make ID theft and fraud rather elementary. But with all that, this book must be read in the larger context of how today's society deals with, and is often oblivious to, risk. When is comes to risk, American society tolerates tens of thousands of drunk-driving deaths, gives millions in federal tobacco subsidies, and is oblivious about near-epidemics such as heart disease, obesity, and diabetes. With all that, it is doubtful that the myriad horror stories Zero Day Threat details will persuade Congress or the other players to do anything to curtail the problem with identity theft and internet fraud." Keep reading for the rest of Ben's review.
Tech: Google Tests Custom Highlights, Comments In Search
Ian Lamont writes "Google is testing functionality that lets users tinker with query results by re-ranking them and commenting on them. The reason for the commenting feature: 'We're just curious to see how it will be used,' according to a Google engineer quoted in the article. The company has posted screenshots of some of the experiments, which also involve highlighting certain results as well as stems and synonyms within results. Google declined to answer any questions about the experiments, and it's not known whether Google would factor the rearranging of results by users into the overall computation for ranking results for those specific queries. It's also not clear whether search result comments would be made available to anyone to read."

Mobile: Space Cube – the World's Smallest Linux PC
Barence writes "Meet the Space Cube — the world's smallest fully functional PC. Primarily designed for use in space, it somehow manages to cram a working PC with USB ports, card readers, audio outputs and proprietary interfaces into a tiny cube chassis measuring just two inches square. It runs a basic Linux front-end, which the blogger takes a look at, and there are some great photos of the device being loomed over by everyday objects like coffee mugs and cellphones. It has connections for controlling various electronics used by ESA, NASA and JAXA, but it will also apparently be for sale to the public soon, for use by amateur engineers and robotics clubs."
Chrb writes "BBC News is reporting that laptops taken to the International Space Station by NASA astronauts are infected with the Gammima.AG worm. The laptops have no net connection; officials suspect the worm may have been transferred via a USB flash drive owned by an astronaut. NASA have said this isn't the first time computer viruses had travelled into space."
