It is possible for every user to obtain root due to a custom faulty memory device created by Samsung.” The problem affects phones with the Exynos System-on-Chip. Read more of this story at Slashdot.
crookedvulture writes “AMD is bundling a stack of the latest games with graphics cards like its Radeon HD 7950. One might expect the Radeon to perform well in those games, and it does. Sort of. The Radeon posts high FPS numbers, the metric commonly used to measure graphics performance. However, it doesn’t feel quite as smooth as the competing Nvidia solution, which actually scores lower on the FPS scale. This comparison of the Radeon HD 7950 and GeForce 660 Ti takes a closer look at individual frame latencies to explain why. Turns out the Radeon suffers from frequent, measurable latency spikes that noticeably disrupt the smoothness of animation without lowering the FPS average substantially. This trait spans multiple games, cards, and operating systems, and it’s ‘raised some alarms’ internally at AMD. Looks like Radeons may have problems with smooth frame delivery in new games despite boasting competitive FPS averages.” Read more of this story at Slashdot.

MrSeb writes with news on the happenings with next generation fabrication processes. From the article: “… Intel’s 22nm SoC unveil is important for a host of reasons. As process nodes shrink and more components move on-die, the characteristics of each new node have become particularly important. 22nm isn’t a new node for Intel; it debuted the technology last year with Ivy Bridge, but SoCs are more complex than CPU designs and create their own set of challenges. Like its 22nm Ivy Bridge CPUs, the upcoming 22nm SoCs rely on Intel’s Tri-Gate implementation of FinFET technology. According to Intel engineer Mark Bohr, the 3D transistor structure is the principle reason why the company’s 22nm technology is as strong as it is. Earlier this year, we brought you news that Nvidia was deeply concerned about manufacturing economics and the relative strength of TSMC’s sub-28nm planar roadmap. Morris Chang, TSMC’s CEO, has since admitted that such concerns are valid, given that performance and power are only expected to increase by 20-25% as compared to 28nm. The challenge for both TSMC and GlobalFoundries is going to be how to match the performance of Intel’s 22nm technology with their own 28nm products. 20nm looks like it won’t be able to do so, which is why both companies are emphasizing their plans to move to 16nm/14nm ahead of schedule. There’s some variation on which node comes next; both GlobalFoundries and Intel are talking up 14nm; TSMC is implying a quick jump to 16nm. Will it work? Unknown. TSMC and GlobalFoundries both have excellent engineers, but FinFET is a difficult technology to deploy. Ramping it up more quickly than expected while simultaneously bringing up a new process may be more difficult than either company anticipates.” Read more of this story at Slashdot.

ShipLives writes “Researchers have tested Google’s app verification service (included in Android 4.2 last month), and found that it performed very poorly at identifying malware in apps. Specifically, the app verification service identified only ~15% of known malware in testing — whereas existing third-party security apps identified between 51% and 100% of known malware in testing.” Read more of this story at Slashdot.

xclr8r writes “A technique to use fiber optics to adjust microscopic particles has been developed. ‘Rather than an actual physical device that wraps around a cell or other microscopic particle to apply rotational force, the spanner (the British term for a wrench) is created when two laser beams — emitted by a pair of optical fibers — strike opposite sides of the microscopic object, trapping and holding it in place. By slightly offsetting the fibers, the beams can impart a small twisting force, causing the object to rotate in place. It is possible to create rotation along any axis and in any direction, depending on the positioning of the fibers.’ Applications of this technology can be used in a number of ways, including cancer research. This technology could be used to actually manipulate DNA. Associate Professor of Physics Samarendra Mohanty states that macroscale applications are a possibility, including ‘direct conversion of solar energy to mechanical energy,’ or possibly using it to ‘simulate an environment in which photons radiated from the sun could propel the reflective motors in solar sails, a promising future technology for deep-space travel.'” Read more of this story at Slashdot.

MrSeb writes “In its continuing mission to build a ‘Wiki Weapon,’ Defense Distributed has 3D printed the lower receiver of an AR-15 and tested it to failure. The printed part only survives the firing of six shots, but for a first attempt that’s quite impressive. And hey, it’s a plastic gun. Slashdot first covered 3D-printed guns back in July. The Defense Distributed group sprung up soon after, with the purpose of creating an open-source gun — a Wiki Weapon — that can be downloaded from the internet and printed out. The Defense Distributed manifesto mainly quotes a bunch of historical figures who supported the right to bear arms. DefDist (its nickname) is seeking a gun manufacturing license from the ATF, but so far the feds haven’t responded. Unperturbed, DefDist started down the road by renting an advanced 3D printing machine from Stratasys — but when the company found out what its machine was being used for, it was repossessed. DefDist has now obtained a 3D printer from Objet, which seemingly has a more libertarian mindset. The group then downloaded HaveBlue’s original AR-15 lower receiver from Thingiverse, printed it out on the Objet printer using ABS-like Digital Material, screwed it into an AR-57 upper receiver, loaded up some FN 5.7x28mm ammo, and headed to the range. The DefDist team will now make various modifications to HaveBlue’s design, such as making it more rugged and improving the trigger guard, and then upload the new design to Thingiverse.” Sensible ammo choice; 5.7x28mm produces less recoil than the AR-15’s conventional 5.56mm. I wonder how many of the upper’s components, too, can one day be readily replaced with home-printable parts — for AR-15 style rifles, the upper assembly is where the gun’s barrel lives, while the lower assembly (the part printed and tested here) is the legally controlled part of the firearm.

Our servers have been unstable and crashing on a regular basis meaning the NZBs & NFOs are unavailable for long periods and we don’t have the money to replace them. To make things worse all our payment providers dropped out or started running scared. The MPA sued Paypal and are going at our innocent payment provider Kthxbai Ltd in the UK.

concealment writes with news of dissatisfaction with a pilot program for stoplight-monitoring cameras. The program ran for several years in New Jersey, and according to a new report, the number of car crashes actually increased while the cameras were present. “[The program] appears to be changing drivers’ behavior, state officials said Monday, noting an overall decline in traffic citations and right-angle crashes. The Department of Transportation also said, however, that rear-end crashes have risen by 20 percent and total crashes are up by 0.9 percent at intersections where cameras have operated for at least a year. The agency recommended the program stay in place, calling for ‘continued data collection and monitoring’ of camera-monitored intersections. The department’s report drew immediate criticism from Assemblyman Declan O’Scanlon, R-Monmouth, who wants the cameras removed. He called the program ‘a dismal failure,’ saying DOT statistics show the net costs of accidents had climbed by more than $1 million at intersections with cameras.” Other cities are considering dumping the monitoring tech as well, citing similar cost and efficacy issues.
