Super-efficient ‘Vulkan’ leaves your games more graphics power

Psst: the games you play might not look as good (or run as smoothly) as they could. In many cases, the overhead from graphics standards gets in the way — Apple went so far as to develop its own technology just to make sure that iPhones and iPads could live up to their potential. That bottleneck may not exist for much longer, however. The alliance behind the OpenGL video standard has given a sneak peek at Vulkan , an open standard that lets app writers take direct control of graphics chips and wring out extra performance on many devices, whether it’s your phone or a hot rod gaming PC. The software isn’t a magic bullet (developers still have to make good use of it), but it could easily lead to richer visuals and smoother frame rates without demanding beefier hardware. Vulkan is still in a preview stage, but it already has some pretty noteworthy support. Valve sees the tech as crucial to Steam Machines , which have to produce gaming-worthy 3D graphics with modest processing power. AMD, ARM, Imagination and NVIDIA also see Vulkan doing wonders with their platforms, although Microsoft’s efforts are going towards DirectX 12 . In short, you’ll probably see better graphics on many platforms — not just in a few gaming-friendly gadgets. Don’t miss out on all the latest from GDC 2015!

Security flaw from the ’90s leaves Apple and Android users vulnerable

A team of cryptographers have discovered that a security flaw from way back in the ’90s still leaves users today vulnerable to cyberattacks. They’ve dubbed it “Factoring attack on RSA-EXPORT Key” or FREAK, and it renders everyone who uses Safari on Mac and iOS devices or Android’s stock browser susceptible to hacking when they visit certain “secure” websites. The researchers listed these affected websites on the study’s official page, and notable entries include government-owned ones, such as Whitehouse.gov, NSA.gov and FBI.gov. To understand what FREAK is, we need to go back to the early 1990s when SSL was in the midst of being developed. Apparently, the US government required companies to use weaker, 512-bit encryption for visitors from overseas, and stronger encryption for visitors stateside. In order to do that, SSL’s developers designed a mechanism that could deliver both. While the government eventually pulled the requirement, it was too late: this mechanism propagated and ended up being used on various software. That’s why during the research, the team managed to force browsers to use the weaker encryption, which one member was able to break within seven hours using the power of 75 computers. In comparison, a 1024-bit encryption would require a team of crackers, the power of a few million PCs, and around a year to hack into. According to Johns Hopkins research professor Matthew Green , this “export-grade” encryption was, in theory, “designed to ensure that the NSA would have the ability to ‘access’ communications, while allegedly providing crypto that was still ‘good enough’ for commercial use.” If this fossil from the era of JNCO pants and MC Hammer can still haunt us today, one has to wonder how NSA’s alleged backdoor entries into company websites and devices can affect us in the future. The researchers can’t say whether anyone already exploited the flaw, but they’ve proved that it can be used to steal a visitor’s personal info, as well as to hack into the affected website itself. Both Apple and Google are already working on a patch: iOS and Mac users can expect the fix for their devices to roll out next week. Android users, however, will have to wait for their manufacturers or carriers to issue an update, so it may be best to switch to Chrome for mobile , which isn’t vulnerable to the flaw, according to The Washington Post .

Tesla warns Model S hacks could injure drivers and its brand

Every year, all publicly traded US companies are required to notify investors of the unique risks to their business. Elon Musk’s Tesla abides by the same rules, and so yesterday laid out an extensive list of factors that it believes could potentially adversely affect its operations. While many of its concerns are to be expected, like worries over the safety of lithium ion batteries used in its cars or the high manufacturing costs of Model S , the company also warned investors that customers intent on pimping their rides could also put a considerable dent in Musk’s electric car empire. In its 10-K document, Tesla notes: “If our vehicle owners customize our vehicles or change the charging infrastructure with aftermarket products, the vehicle may not operate properly, which could harm our business.” The company specifically references “automobile enthusiasts” who want to hack their Tesla to improve its performance, warning that those who do may compromise the safety systems. It says some customers have already sought to modify their position in the driving seat, which reduces the effectiveness of the airbags. “We have not tested, nor do we endorse, such changes or products. In addition, customer use of improper external cabling or unsafe charging outlets can expose our customers to injury from high voltage electricity, ” says Tesla. “Such unauthorized modifications could reduce the safety of our vehicles and any injuries resulting from such modifications could result in adverse publicity which would negatively affect our brand and harm our business, prospects, financial condition and operating results.” Even though Tesla is rapidly growing its customer base, the company is still a minnow in a big automotive pond. Because it’s also helping to drive the adoption of electric cars, it has also had to deal with questions over safety, following reports that some of its vehicles caught fire after being involved in an accident . Tesla is basically admitting that it has no control over what its customers do with their cars, but knows that if some plucky tinkerer touches the wrong wire, it will be the one who has to deal with the fallout.

Linux 4.0 Getting No-Reboot Patching

An anonymous reader writes: ZDNet reports that the latest changes to the Linux kernel include the ability to apply patches without requiring a reboot. From the article: “Red Hat and SUSE both started working on their own purely open-source means of giving Linux the ability to keep running even while critical patches were being installed. Red Hat’s program was named kpatch, while SUSE’ is named kGraft. … At the Linux Plumbers Conference in October 2014, the two groups got together and started work on a way to patch Linux without rebooting that combines the best of both programs. Essentially, what they ended up doing was putting both kpatch and kGraft in the 4.0 Linux kernel.” Note: “Simply having the code in there is just the start. Your Linux distribution will have to support it with patches that can make use of it.” Read more of this story at Slashdot.

Metallica is releasing a remastered 1982 demo… on cassette

Dust off your tape players , folks: cassettes are still making a comeback. A number of independent artists have already leveraged the classic format, and Metallica is looking to join the bandwagon. The metal act recorded the seven-track No Life ‘Til Leather demo back in 1982, and the effort will be released on April 18th as a limited-edition cassette. If you tossed out that boombox a long time ago, the remastered tunes will be available on CD and vinyl this summer. This is the first time that any of the band’s demo material has been officially released , and it’s the first in a series of reissues planned through Blackened Recordings, a Metallica-owned label. “It’s time for us to put out some next-level reissues and do the song and dance of the catalog that everyone else has done; the U2s and the Led Zeppelins and the Oasises, ” drummer Lars Ulrich told Rolling Stone . “Instead of starting with Kill ‘Em All in 1983, we figured we’d go back another two years to when the band was formed in 1981.” Personally, I’m hoping the remastered version of Master of Puppets isn’t too far off.
