Submission + - New supernova seen in nearby galaxy M82

The Bad Astronomer writes: A new and potentially bright supernova was just discovered in the nearby galaxy M82. This is a Type Ia supernova, the catastrophic explosion of a white dwarf. It appears to be on the rise, and may have been caught as much as two weeks before peak brightness. It's currently already brighter than magnitude 12, and may get to mag 8, easy to see in small telescopes. The galaxy is less than 12 million light years away, so this may become one of the best-studied supernovae in recent times. Type Ia supernovae are used to measure dark energy, so seeing one nearby is a huge boon to astronomy.

Submission + - Intel has acquired Whamcloud, the company behind Lustre (whamcloud.com)

An anonymous reader writes: In an unsuspected move, Intel and Whamcloud announced that the former acquired the latter. The Lustre filesystem, a well known and widely adopted parallel filesystem for high performance computing, is now part of Intel's portfolio, after having been owned by CFS, Sun, Oracle and Whamcloud.
Now that it's controlled by a giant multinational corporation, will Lustre remain open source ?


Submission + - Air Force Wants Reusable Fly-back Rockets (discovery.com)

FleaPlus writes: The Air Force is initiating a pathfinder program to develop a first-stage rocket booster capable of gliding back to a runway so it can be easily reused. Lockheed Martin has already launched a secretive prototype, as well as a Cal Poly team with a prototype based on Buzz Aldrin's Starcraft/StarBooster design (video). The Air Force estimates such a booster could cut launch costs by 50% over the current Atlas 5 and Delta 4 rockets, and could also offer a rapid surge/replacement capability if combined with reusable spacecraft like the recently-launched X-37B. Initial test flights are planned for 2013.

Submission + - Hackers Can Delete Facebook Friends (computerworld.com)

CWmike writes: A bug in Facebook's Web site lets hackers delete Facebook friends without permission. The flaw was reported on Wednesday by Steven Abbagnaro, a student at Marist College in Poughkeepsie, New York. But as of Friday morning, Pacific time, it had still not been patched, based on tests conducted by the IDG News Service on a reporter's Facebook friends list. The security researcher is not going to release the code used in his attack until after Facebook fixes the flaw, but he says that technically competent hackers could figure out how to pull off the attack. That's because Abbagnaro's code exploits the same underlying flaw that was first reported by M.J. Keith, a senior security analyst with Alert Logic. Last week, Keith discovered that Facebook's Web site was not properly checking code sent by users' browsers to ensure that they were authorized to make changes on the site. Facebook's security team has been under siege lately, with worm attacks and site flaws popping up on a regular basis. These security issues come as the social network has been hit with intense criticism for not adequately protecting users' privacy, and inappropriately sharing user data with advertisers. Users have been quitting the social network and a campaign proclaiming May 31 as Quit Facebook Day has gained some traction. According to the results a new Sophos poll, more than half of Facebook users are considering dumping the site because of privacy concerns.

Submission + - 3D or not 3D: Should we have 3D as a design option (usixml.org)

jumagoca78 writes: During many years three-dimensional interactive systems have shown to be helpful to major industries: medical imagery, architectural drawing, computer-assisted design and scientific simulations. 3D in not anymore present in complex system we can access virtual world in a desktop computer in video games, 3D chat rooms (www.imvu.com), 3D social networks (www.exitreality.com), 3D browsers (www.spacetime.com). Still it is hard to find some design knowledge to be guided if I want to build such kind of virtual worlds. Tutorials are always focusing on how to develop the content but what about the 3D User Interface? Those controls that are use, for instance, to purchase a product in a virtual shop. In space time (www.spacetime.com) the 3D metaphor breaks as soon as you want to interact with a window. Should we keep those applications in 2D? If not, in the virtual world, what metaphor should be used for the controls? Should we just imitate what it already exist in 2D GUI but rendered in 3D? Should we go beyond that with innovative representation of traditional widgets? When designing a solution should we have 3D as a design option?

Submission + - Heart patient with no pulse (straitstimes.com) 2

laggist writes: "Heart patient in Singapore implanted with artificial heart that pumps blood continuously, allowing her to be very alive without a pulse.

From the article: '.. the petite Madam Salina, who suffers from end-stage heart failure, would not have been able to use the older and bulkier models because they can only be implanted in patients 1.7m or taller. The 30-year-old administrative assistant is the first recipient here to get a new artificial heart that pumps blood continuously, the reason why there are no beats on her wrist.'"


Submission + - SPAM: Toyota, Lexus Recalling 3.8 Million Vehicles to In

Hondagrrl writes: "This might not be such a well-publicized issue if not for the tragic deaths of a California Highway Patrol Officer and three members of his family last month. While the exact cause of the accident has not yet been proven, initial police reports say his speeding 2009 Lexus ES could not be stopped because the driver's floor mat had interfered with the pedals."

G20 Protesters Blasted By "Sound Cannon" 630

aaandre sends word of the use of a "sound cannon" on G20 protesters in Pittsburgh. Only a few hundred protesters took to the streets. The NY Times notes: "City officials said they believed it was the first time the sound cannon had been used publicly." The device projects a narrow beam of extremely annoying sound, at levels that can reach 151 decibels, over a distance of a mile or more. The Guardian notes, "It is feared the sounds emitted are loud enough to damage eardrums and even cause fatal aneurysms." Officials of the company that manufactures the sound cannon say that ear damage is only possible if someone manages to stand directly in front of the device for an extended period.

Submission + - Travel to the Edge of the Universe (arxiv.org)

An anonymous reader writes: It is well known that interstellar travel is bounded by the finite speed of light, but on very large scales any rocketeer would also need to consider the influence of cosmological expansion on their journey. This paper examines accelerated journeys within the framework of Friedmann- Lemaitre-Robertson-Walker universes, illustrating how the duration of a fixed acceleration sharply divides exploration over interstellar and intergalactic distances. Furthermore, we show how the universal expansion increases the difficulty of intergalactic navigation, with small uncertainties in cosmological parameters resulting in significantly large deviations. This paper also shows that, contrary to simplistic ideas, the motion of any rocketeer is indistinguishable from Newtonian gravity if the acceleration is kept small.

Submission + - Canadian Pirate Party close to registering in upco

I cant believe its n writes: "In a ZeroPaid interview with Jake Daynes, a spokesperson for the Pirate Party of Canada, it was revealed that althought the party was started in 2009, they are now only 250 members away from registering in the upcoming lections.

ISP Emails Customer Database To Thousands 259

Barence writes "British ISP Demon Internet has mistakenly sent out a spreadsheet containing the personal details of more than 3,600 customers with one of its new ebills. The spreadsheet contains email addresses, telephone numbers and what appears to be usernames and passwords for the ebilling system. It was attached to an email explaining how to use the new system. Police forces and NHS trusts are among the email addresses listed in the database. A spokesman for Demon Internet confirmed that the company "was aware this happened this morning"."

An anonymous reader writes: Wired Magazine has a new story posted about the Doomsday Machine built by the Soviet Union in the 1980s---and that remains active today. It explains why the device was built, and why the Soviets considered it to be something that kept the peace, event though they never told the U.S. about it.
