RobGoldsmith writes "Earlier this week images were appearing on the Net showing the WhiteKnightTwo craft doing some tests in Mojave. The earliest tests showed perhaps two of the engines being used, while a later test showed all the engines working and some further testing. Today the four Pratt & Whitney Canada PW308A engines finally carried the craft into the air. The maiden flight of the WhiteKnightTwo lasted just shy of one hour and happened today at around 08:15 local time, at Mojave air and spaceport. Rumors suggest that a Beechcraft King Air was used for a chase plane. The craft will be used to position Virgin Galactic's SpaceShipTwo craft to fly into space; this is estimated to happen around 2010."

WorldWarCheese writes "Many's the time I wish I had a little more mobility or comfort with my computer. Laptops are OK, but anyone interested can see right onto my screen; and a laptop doesn't quite have that 'cool' factor that VR goggles / headsets do. The problem is, whenever I've looked at the options, Linux compatibility is not mentioned. Is there a VR headset out there that is compatible with Ubuntu? If not, what could I do to make it compatible, and how feasible would that be?"

iandoh passes along the news that researchers at Stanford University have completed the first quantitative, scientific comparison of alternative energy solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability, and sustainability. Based on their model, they found that the best sources of alternative energy are wind, concentrated solar, and geothermal energy. The worst are nuclear, clean coal, and ethanol-based fuels. In other words, "the options that are getting the most attention are between 25 to 1,000 times more polluting than the best available options."

jamie points out an interesting story which started a few days ago, when a pair of students from the Netherlands released a Firefox add-on which integrated links to the Pirate Bay on Amazon product pages. Customers who had the add-on would see a large "Download 4 Free" button next to items which were also available on the Pirate Bay. The add-on quickly drew notice, and the creators were hit with a take-down notice and threats of litigation from Amazon. Now, the students have removed the add-on, and they are claiming an unusual defense: "'Pirates of the Amazon' was an artistic parody, part of our media research and education at the Media Design M.A. course at the Piet Zwart Institute of the Willem de Kooning Academy Hogeschool Rotterdam, the Netherlands. It was a practical experiment on interface design, information access and currently debated issues in media culture. We were surprised by the attentions and the strong reactions this project received. Ultimately, the value of the project lies in these reactions. It is a ready-made and social sculpture of contemporary internet user culture."

theodp writes "The USPTO has granted IBM a patent for utilizing naming conventions to assign gender-based avatars for instant messaging. A user named Teri, IBM explains, would be given a girl avatar, while a user named Terry would be provided with a boy avatar. The three IBM 'inventors' were stymied by users named Pat, who as a result will be assigned a 'generic, genderless human figure image as his or her avatar.' Way to honor that significant-technical-content patent pledge, Big Blue!"

Gwaihir the Windlord writes "A university in Western Australia has started beta testing a tool that's described as 'a random breath test' to scan computers for illicit images. According to this article it's a clean bootable Linux environment. Since it doesn't write to the hard drive, the evidence is acceptable in court, at least in Australia. They're also working on versions to search for financial documents in fraud squad cases, or to search for terrorist keywords. Other than skimming off the dumb ones, does anyone really expect this to make a difference?" The article offers no details on what means the software uses to identify suspicious files.

Death Metal sends in a Scientific American article reporting that 2,000 of 6,000 amphibian species are endangered worldwide. A combination of environmental assaults, including global warming, seems to be responsible. "... national parks and other areas protected from pollution and development are providing no refuge. The frogs and salamanders of Yellowstone National Park have been declining since the 1980s, according to a Stanford University study, as global warming dries out seasonal ponds, leaving dried salamander corpses in their wake. Since the 1970s, nearly 75 percent of the frogs and other amphibians of La Selva Biological Station in Braulio Carrillo National Park in the Caribbean lowlands of Costa Rica have died, perhaps due to global warming. But the really bad news is that amphibians may be just the first sign of other species in trouble. Biologists at the University of California, San Diego, have shown that amphibians are the first to respond to environmental changes, thanks to their sensitivity to both air and water. What goes for amphibians may soon be true of other classes of animal, including mammals."

vile8 writes "With the high gas prices and ongoing gas gouging in my hometown many people are trying to find a reasonable way to save gas. One of the things I've noticed is people driving exceptionally slow, 30mph in 45mph zones, etc. So I had to take a quick look and find out if driving slow is helpful in getting better mileage. I know horsepower increases substantially with wind resistance, but with charts like this one from truckandbarter.com it appears mileage is actually about the same between 27mph and 58mph or so. So I'm curious what all the drivers out there with the cool efficiency computers are getting ... of specific interest would be the hemis with MDS; how do those do with the cylinder shutoff mode at different speeds?" Related: are there any practical hypermiling techniques that you've found for people not ready to purchase a new car, nor give up driving generally?
