Submission + - Curiosity Rover Finds "Ancient Streambed" Proving Mars Once Had Water (twitter.com) 3

eldavojohn writes: As NPR reports, NASA's Curiosity Rover has tweeted pictures of proof of water on Mars. Indications arose earlier this year but researchers are now calling this proof of a stream ankle to hip deep running at about three feet per second judging by the pictures. The shapes prove these rocks were weathered as they were transported by something and the sizes tell you that that something couldn't be wind.

Submission + - Sharp develops see-through solar panel for windows (geek.com)

An anonymous reader writes: Solar power may hold the promise of free energy from the sun, but the panels used are expensive and do take up a lot of room. Typically you’ll find them installed on a roof or filling an area of land next to the building requiring the green energy. But now Sharp is offering up a third option: solar panels that double as windows.

Sharp has managed to develop a solar panel that takes the form of a sheet of glass and only partially blocks light passing through it. That allows it to still generate energy, but also act as a window. Sharp achieved this by cutting tiny slits in thin-film silicon PV cells. The trade-off for cutting into the cells is lower energy generation. Sharp can currently produce the see-through panels at sizes up to 1.4 x 1.0 meters, and a thickness of just 9.5mm. Each panel weighs 33kg and can produce a maximum output of 95W. Pricing has not yet been revealed.


Ubuntu Linux vs. Mac OS X 479

An anonymous reader writes "An article on InformationWeek pits an Apple user against an Ubuntu Linux user (although he talks about other distros as well) as to which OS makes a better desktop operating system. As might be expected, the conclusion seems to be "different strokes for different folks," but it's interesting to see Microsoft cut (mostly) out of the equation."

Submission + - Linux Gains Two New Virtualization Solutions

An anonymous reader writes: The upcoming 2.6.23 kernel has gained two new virtualization solutions. According to KernelTrap, both Xen and lguest have been merged into the mainline kernel. These two virtualization solutions join the already merged KVM, offering Linux multiple ways to run multiple virtual machines each running their own OS.

Submission + - On the rPath to virtual containerization (interopnews.com)

willdavid writes: "According to Jeff Gould, it's becoming increasingly clear that the most important use of virtualization is not to consolidate hardware boxes but to protect applications from the vagaries of the operating environments they run on. It's all about "containerization." He talks about how Linux applications could be distributed much easier using a fully integrated OS-middleware-application stack. http://www.interopnews.com/news/on-the-rpath-to-vi rtual-containerization.html"
