Steam Machine Prototypes Use Intel CPUs, NVIDIA GPUs

An anonymous reader writes “Valve has revealed their first Steam Machines prototype details. The first 300 Steam Machine prototypes to ship will use various high-end Intel CPUs and NVIDIA GPUs while running their custom SteamOS Linux distribution. The Intel Haswell CPU + NVIDIA GPU combination should work well on Linux with the binary drivers. Using a range of CPUs/GPUs in the prototypes will allow them to better gauge the performance and effectiveness. Valve also said they will be releasing the CAD design files to their custom living room console enclosure for those who’d like to reproduce them.” Valve is careful to point out that these specs aren’t intended as a standard: “[T]o be clear, this design is not meant to serve the needs of all of the tens of millions of Steam users. It may, however, be the kind of machine that a significant percentage of Steam users would actually want to purchase — those who want plenty of performance in a high-end living room package. Many others would opt for machines that have been more carefully designed to cost less, or to be tiny, or super quiet, and there will be Steam Machines that fit those descriptions.” Read more of this story at Slashdot.

Students Hack School-Issued iPads Within One Week

Hugh Pickens DOT Com writes “Los Angeles Unified School District started issuing iPads to its students this school year, as part of a $30 million deal with Apple. Now Sam Sanders reports at NPR that less than a week after getting their iPads, high school students have found a way to bypass software blocks on the devices that limit what websites the students can use. The students are getting around software that lets school district officials know where the iPads are, what the students are doing with them at all times and lets the district block certain sites, such as social media favorites like Facebook. ‘They were bound to fail, ‘ says Renee Hobbs, who’s been a skeptic of the iPad program from the start. ‘There is a huge history in American education of being attracted to the new, shiny, hugely promising bauble and then watching the idea fizzle because teachers weren’t properly trained to use it and it just ended up in the closet.’ The rollout of the iPads might have to be delayed as officials reassess access policies. Right now, the program is still in Phase 1, with fewer than 15, 000 iPads distributed. ‘I’m guessing this is just a sample of what will likely occur on other campuses once this hits Twitter, YouTube or other social media sites explaining to our students how to breach or compromise the security of these devices, ‘ says Steven Zipperman. ‘I want to prevent a “runaway train” scenario when we may have the ability to put a hold on the roll-out.’ The incident has prompted questions about overall preparations for the $1-billion tablet initiative.” Read more of this story at Slashdot.

Sleep Found To Replenish a Type of Brain Cell

New submitter wrackspurt writes “Sleep deprivation has long been thought to be prevalent in the industrialized world. A new study (abstract) explains one very good reason why at least seven hours of sleep a night is necessary. Quoting the BBC: ‘Sleep ramps up the production of cells that go on to make an insulating material known as myelin which protects our brain’s circuitry. … The increase was most marked during the type of sleep that is associated with dreaming – REM or rapid eye movement sleep — and was driven by genes. In contrast, the genes involved in cell death and stress responses were turned on when the mice were forced to stay awake.'” Read more of this story at Slashdot.

U.S. District Judge: Forced Decryption of Hard Drives Violates Fifth Amendment

hansamurai writes with an update to a story we’ve been following for a while. Jeffrey Feldman is at the center of an ongoing case about whether or not crime suspects can be forced to decrypt their own hard drives. (Feldman is accused of having child pornography on his hard drives.) After initially having a federal judge say Feldman was protected by the Fifth Amendment, law enforcement officials were able to break the encyption on one of his many seized storage devices. The decrypted contents contained child pornography, so a different judge said the direct evidence of criminal activity meant Feldman was not protected anymore by the Fifth Amendment. Now, a third judge has granted the defense attorney’s emergency motion to rescind that decision, saying Feldman is once again (still?) protected by the Fifth Amendment. Feldman’s lawyer said, “I will move heaven and earth to make sure that the war on the infinitesimal amount of child pornography that recirculates on the Internet does not eradicate the Fifth Amendment the way the war on drugs has eviscerated the Fourth Amendment. This case is going to go many rounds. Regardless of who wins the next round, the other side will appeal, invariably landing in the lap of the Seventh Circuit Court of Appeals and quite possibly the U.S. Supreme Court. The grim reality facing our country today is one where we currently have a percentage of our population behind bars that surpasses even the heights of the gulags in Stalinist Russia. On too many days criminal lawyers lose all rounds. But for today: The Shellow Group: 1, Government: 0.” Read more of this story at Slashdot.

Genetically Modified Plants To Produce Natural Lighting

kkleiner writes “A team has launched a crowdsourcing campaign to develop sustainable natural lighting by using a genetically modified version of the flowering plant Arabidopsis. Using the luciferase gene, the enzyme responsible for making fireflies glow, the researchers will design, print, and transform the genes into the target plant. The project, which was recently launched on Kickstarter, has already raised over $100k with over a month left to go.” Read more of this story at Slashdot.

DOE Wants 5X Improvement In Batteries In 5 Years

dcblogs writes “The U.S. Dept. of Energy has set a goal to develop battery and energy storage technologies that are five times more powerful and five times cheaper within five years. DOE is creating a new center at Argonne National Laboratory, at a cost of $120 million over five years, that’s intended to reproduce development environments that were successfully used by Bell Laboratories and World War II’s Manhattan Project. ‘When you had to deliver the goods very, very quickly, you needed to put the best scientists next to the best engineers across disciplines to get very focused,’ said U.S. Energy Secretary Stephen Chu, on Friday. The Joint Center for Energy Storage Research isn’t designed to seek incremental improvements in existing technologies. This technology hub, according to DOE’s solicitation (PDF), ‘should foster new energy storage designs that begin with a “clean sheet of paper” — overcoming current manufacturing limitations through innovation to reduce complexity and cost.’ Other research labs, universities and private companies are participating in the effort.” Read more of this story at Slashdot.
