Vigile writes "When NVIDIA released the GTX Titan in February, it was the first consumer graphics card to use the GK110 GPU from NVIDIA that included 2,688 CUDA cores / shaders and an impressive 6GB of GDDR5 frame buffer. However, it also had a $1000 price tag that was the limiting specification for most gamers. With today's release of the GeForce GTX 780 they are hoping to utilize more of the GK110 silicon they are getting from TSMC while offering a lower cost version with performance within spitting range. The GTX 780 uses the same chip but disables a handful more compute units to bring the shader count down to 2,304 — still an impressive bump over the 1,536 of the GTX 680. The 384-bit memory bus remains though the frame buffer is cut in half to 3GB. Overall, the performance of the new card sits squarely between the GTX Titan ($1000) and AMD's Radeon HD 7970 GHz Edition ($439), just like its price. The question is, are PC gamers willing to shell out $220+ dollars MORE than the HD 7970 for somewhere in the range of 15-25% more performance?" As you might guess, there's similarly spec-laden coverage at lots of other sites, including Tom's, ExtremeTech, and TechReport.

Nyder writes "Kim Dotcom posted via Twitter, with a link to Torrentfreak, that he owns a security patent US6078908, titled 'Method for authorizing in data transmission systems.'" Techdirt points out that Dotcom isn't just asking for financial help: Instead, he's asking companies which use two-factor authentication "to help fund his defense, in exchange for not getting sued for the patent. He points out that his actual funds are still frozen by the DOJ and (more importantly) that his case actually matters a great deal to Google, Facebook and Twitter, because the eventual ruling will likely set a precedent that may impact them -- especially around the DMCA." Update: 05/23 14:23 GMT by T : Why is this relevant to Twitter? If you're not an active Twitter user, you might not realize that (after some well publicized twitter-account hijackings), the company is trying to regain some ground on security. Nerval's Lobster writes "Twitter is now offering two-factor authentication, a feature that could help prevent embarrassing security breaches. Twitter users interested in activating two-factor authentication will need to head over to their account settings page and click the checkbox beside 'Require a verification code when I sign in.'"

judgecorp writes "Supporters of the Communications Data Bill (also known as the Snooper's Charter) have lost no time in calling for the Bill to be revived, in response to yesterday's brutal murder of a soldier on the streets of Woolwich, South London. The Bill would have allowed monitoring of all online communications — including who people contact and what websites they visit — but was shelved after Deputy Prime Minister Nick Clegg opposed it, effectively splitting Britain's coalition government on the issue. Now the fear of new terrorism could rekindle support, based on the argument that even 'lone wolf' attackers use the Internet."

zrbyte writes "One-time pads are the holy grail of cryptography — they are impossible to crack, even in principle. However, the ability to copy electronic code makes one-time pads vulnerable to hackers. Now engineers at the California Institute of Technology in Pasadena, have found a way around this to create a system of cryptography that is invulnerable to electronic attack. Their solution is based on a special kind of one-time pad that generates a random key through the complexity of its physical structure, namely shining a light through a diffusive glass plate."

walterbyrd writes "Late last year, a vigorous and secretive patent troll began sending out thousands of letters to small businesses all around the country, insisting that they owed between $900 and $1,200 per worker just for using scanners. The brazen patent-trolling scheme, carried out by a company called MPHJ technologies and dozens of shell companies with six-letter names, has caught the attention of politicians. MPHJ and its principals may have gone too far. They're now the subject of a government lawsuit targeting patent trolling—the first ever such case. Vermont Attorney General William Sorrell has filed suit in his home state, saying that MPHJ is violating Vermont consumer-protection laws."

An anonymous reader writes "Within a few months of launching, Snapchat has made an enormous and lasting impact on the culture of communication on the Internet – and we should all be grateful. They have simplified a security process enough to the point that anybody can use it, while validating the market of the next generation of privacy-preserving ephemeral communication. Most importantly, we may finally get a break from the forced permanence of the Facebook and Google world, where everything you do and share is a data point to be monetized and re-sold to the highest bidder."

antdude writes "Pew Internet reports that: 'Teens are sharing more info about themselves on social media sites than they have in the past, but they are also taking a variety of technical and non-technical steps to manage the privacy of that information. Despite taking these privacy-protective actions, teen social media users do not express a high level of concern about third-parties (such as businesses or advertisers) accessing their data.'"

sciencehabit writes "Physicists have long known that quantum mechanics allows for a subtle connection between quantum particles called entanglement, in which measuring one particle can instantly set the otherwise uncertain condition, or 'state,' of another particle—even if it's light years away. Now, experimenters in Israel have shown that they can entangle two photons that don't even exist at the same time. Anton Zeilinger, a physicist at the University of Vienna, says that the experiment demonstrates just how slippery the concepts of quantum mechanics are. 'It's really neat because it shows more or less that quantum events are outside our everyday notions of space and time.'"

The Bad Astronomer writes "A Minuteman III missile launch from California early Wednesday morning created a weird, expanding halo of light seen from the CFHT observatory on Hawaii's Mauna Kea. The third stage of the missile has ports that open and dump fuel into the near-vacuum. This cloud expands rapidly as a spherical shell, shock-exciting the air molecules and causing them to glow, creating the bizarre effect."

First time accepted submitter Bas_Wijnen writes "3D printing is being condemned in the media because of the potential for printing guns. Engineers at Michigan Tech believe there is far more potential for 3D printers to make our lives better rather than killing one another. To encourage thinking about constructive uses of 3D printing technology Michigan Tech Open Sustainability Technology (MOST) Lab and Type A Machines sponsor the first 3-D Printers for Peace Contest. Designers are encouraged to consider: If Mother Theresa of Ghandi had access to 3D printing what would they print? What kind of designs could help reduce military spending and conflict while making us all safer and more secure? Anyone in the United States may enter and there is no cost."

An anonymous reader writes "The open-source Intel Linux graphics driver has hit a milestone of now being faster than Apple's own OpenGL stack on OS X. The Intel Linux driver on Ubuntu 13.04 is now clearly faster than Apple's internally-developed Intel OpenGL driver on OS X 10.8.3. when benchmarked from a 'Sandy Bridge' class Mac Mini. Only some months ago, Apple's GL driver was still trouncing the Intel Linux Mesa driver."

astroengine writes "In a recent batch of images beamed back to Earth from Mars rover Curiosity's MAHLI camera, obvious signs of wear and tear could be seen in the 'skin' of the robot's wheels. Considering Curiosity is only 281 sols (Mars days) into its mission and roved less than a kilometer after landing, surely this doesn't bode well? Fortunately, there's good news. 'The wear in the wheels is expected,' Matt Heverly, lead rover driver for the MSL mission at NASA's Jet Propulsion Laboratory in Pasadena, Calif., told Discovery News. 'We will continue to characterize the wheels both on Mars and in the Marsyard, but we don't expect the wear to impact our ability to get to Mt. Sharp.'"

Tesla Motors announced today it has completely repaid the $465 million loan from the U.S. Department of Energy the company received in 2010. The funds were generated by Tesla through a recent sale of their stock, worth close to a billion dollars. The stock price had risen sharply after the company reported its first profitable quarter (and the stock still sits roughly 50% higher than before their earnings release). Today's payment of $451.8 million finished off both the loan's principal and its interest, nine years before the final payment was due. Tesla CEO Elon Musk said, 'I would like to thank the Department of Energy and the members of Congress and their staffs that worked hard to create the ATVM program, and particularly the American taxpayer from whom these funds originate. I hope we did you proud.'
