Valve Open Sources Their DirectX To OpenGL Layer
jones_supa writes "A bit surprisingly, Valve Software has uploaded their Direct3D to OpenGL translation layer onto GitHub as open source. It is provided as-is and with no support, under the MIT license allowing you to do pretty much anything with it. Taken directly from the DOTA2 source tree, the translation layer supports limited subset of D3D 9.0c, bytecode-level HLSL to GLSL translator, and some SM3 support. It will require some tinkering to get it to compile, and there is some hardcoded Source-specific stuff included. The project might bring some value to developers who are planning to port their product from Windows to Linux."

How Engineers Are Building a Power Station At the South Pole
KentuckyFC writes "One of the more ambitious projects at the South Pole is the Askaryan Radio Array, a set of radio antennas under the ice that will listen for the tell tale signals of high energy neutrinos passing by. This array will eventually be over a thousand times bigger than the current largest neutrino detector: Icecube, which monitors a cubic kilometer of ice next door to the planned new observatory. But there's a problem. How do you supply 24/7 power to dozens of detectors spread over such a vast area in the middle of the Antarctic? The answer is renewable energy power stations that exploit the sun during the summer and the wind all year round. The first of these stations is now up and running at the South Pole and producing power. It is also helping to uncover and iron out the various problems that these stations are likely to encounter. For example; where to put the batteries needed to supply continuous power when all else fails. The team's current approach is to bury the battery to protect it from temperature extremes. That works well but makes maintenance so difficult that scaling this approach to dozens of power stations doesn't seem feasible. That's a problem for the future but for the moment, green power has finally come to the white continent."

Sony & Panasonic Next-Gen Optical Discs Moving Forward
jones_supa writes "From last summer you might remember the Sony & Panasonic plans to bring next generation optical discs with recording capacity of at least 300GB. Various next-gen optical discs from different companies have been proposed, but this joint effort seems to be still moving forward. The disc is called simply Archival Disc and, roadmap and key specifications are out. First-wave ADs are slated to launch in summer of 2015 and will be able to hold up to 300GB of data. Archival Discs will be double-sided, so this works out to 150GB of data per side. Future versions of the technology will improve storage density, increasing to 500GB (or 250GB per side) and 1TB (500GB per side) as the standard matures."

US Intelligence Officials To Monitor Federal Employees With Security Clearances
First time accepted submitter Trachman writes in with news about a monitoring program designed to help stop future leaks of government documents. "U.S. intelligence officials are planning a sweeping system of electronic monitoring that would tap into government, financial and other databases to scan the behavior of many of the 5 million federal employees with secret clearances, current and former officials told The Associated Press. The system is intended to identify rogue agents, corrupt officials and leakers, and draws on a Defense Department model under development for more than a decade, according to officials and documents reviewed by the AP."

Google Blocking Asus's Android-Windows "Duet"?
theodp writes "Android is free and open," reiterated Google Android Chief Andy Rubin in 2010 as Microsoft launched Windows Phone 7. Rubin added, 'Competition is good for the consumer and if somebody has an idea for a feature or a piece of functionality in their platform and Android doesn't do it, great. I think it's good to have the benefit of choice, but in the end I don't think the world needs another platform.' But now, CNET and Digitimes report that Google is holding up the Asus Transformer Book Duet TD300 (specs), a laptop-tablet hybrid that can instantly switch between Android and Windows 8.1. A source familiar with the Asus Duet told CNET that Google is the one that has not favored the idea, while Microsoft has not, to date, been actively opposed to the idea. 'If true,' reports Apple Insider, 'it may not be the first time Google has helped to quash such a product.' South Korean electronics giant Samsung quietly canceled plans for its hybrid Ativ Q tablet last year, and Digitimes notes that Asus may not be the only company to bow to Google's wishes."

SpaceX Wants To Go To Mars — and Has a Plan To Get There
mknewman writes with an article at NASA SpaceFlight which lays out the details of a plan from SpaceX to send a craft to Mars, using an in-development engine ("Raptor") along with the company's Super Heavy Lift Launch Vehicle. "Additionally, Mr. Musk also introduced the mysterious MCT project, which he later revealed to be an acronym for Mars Colonial Transport. This system would be capable of transporting 100 colonists at a time to Mars, and would be fully reusable. Article is technically dense but he does seem to follow through on his promises!" This is an endeavor that's been on Elon Musk's mind for a while.

Ars Technica Reviews Leaked Windows 8.1 Update
SternisheFan writes to note that ArsTechnica's Peter Bright has reviewed the leaked Windows 8.1 update that was temporarily available from Microsoft's own servers. Here's how the article starts: "Leaks of upcoming versions of Microsoft's software are nothing new, but it's a little surprising when the source is Microsoft itself. The Spring update to Windows 8.1, known as Update 1, was briefly available from Windows Update earlier this week. The update wasn't a free-for-all. To get Windows Update to install it, you had to create a special (undocumented, secret) registry key to indicate that you were in a particular testing group; only then were the updates displayed and downloadable. After news of this spread, Microsoft removed the hefty—700MB—update from its servers, but not before it had spread across all manner of file-sharing sites... Just because it was distributed by Windows Update doesn't mean that this is, necessarily, the final build, but it does present a good opportunity to see what Microsoft is actually planning to deliver."

The Tangled Tale of Mt. Gox's Missing Millions
jfruh writes "What went wrong to produce the spectacular implosion of bitcoin repository Mt. Gox? Well, according to some preliminary investigation from the IDG News Service, pretty much everything. There was a lack of management oversight and 'culture,' the code running the site was a mess, and the CEO seemed more concerned about his plans for a 'Bitcoin cafe' than he was about his Japanese bank closing the company's account."

Samsung Galaxy Glass Patent Plans To Turn Fingers Into a Keyboard
rjmarvin writes "Samsung looks to have found a way around voice commands for smart glasses by projecting an augmented reality keyboard onto users' hands. Galaxy Glass wearers' thumbs are used as input devices, tapping different areas of their fingers where various keys are virtually mapped. According to the August 2013 patent filing with the WIPO and South Korea's Intellectual Property Office, Samsung states that voice controls are too imprecise a technology, which are too heavily impacted by the noise levels of the surrounding environment."

Facebook Wants To Block Illegal Gun Sales
Nerval's Lobster writes "Most of the time, Facebook allows its users to hawk goods or solicit donations on Pages or Timeline postings, comparing such activity to placing a physical note on a bulletin board at a supermarket. Now it plans on regulating users who rely on this method to sell what it calls 'regulated' items, which includes firearms. 'Any time we receive a report on Facebook about a post promoting the private sale of a commonly regulated item, we will send a message to that person reminding him or her to comply with relevant laws and regulations. We will also limit access to that post to people over the age of 18,' Facebook announced as part of the new rules. The social network will also prevent users from posting any sort of items 'that indicate a willingness to evade or help others evade the law,' which means no offers to sell firearms across state lines or without a background check. Presumably, Facebook will have filters in place that allow it to scan for such content. Facebook is a private network, of course, and not (despite its ubiquity) a public utility — meaning it can do whatever it wants with regard to Terms of Use. But that likely won't stop some people from complaining about what they perceive as the company overstepping its boundaries."

Low-Protein Diet May Extend Lifespan
sciencehabit writes "A new theory about the foods that can extend life is taking shape, and it's sure to be a controversial one. Two studies out this week, one in mice (PDF) and another primarily in people (PDF), suggest that eating relatively little protein and lots of carbohydrates — the opposite of what's urged by many human diet plans, including the popular Atkins Diet — extends life and fortifies health."

Google Won't Enable Chrome Video Acceleration Because of Linux GPU Bugs
An anonymous reader writes "Citing 'code we consider to be permanently "experimental" or "beta,"' Google Chrome engineers have no plans on enabling video acceleration in the Chrome/Chromium web browser. Code has been written but is permanently disabled by default because 'supporting GPU features on Linux is a nightmare' due to the reported sub-par quality of Linux GPU drivers and many different Linux distributions. Even coming up with a Linux GPU video acceleration white-list has been shot down over fear of the Linux video acceleration code causing stability issues and problems for Chrome developers. What have been your recent experiences with Linux GPU drivers?"

Teaching Calculus To 5-Year-Olds
Doofus writes "The Atlantic has an interesting story about opening up what we routinely consider 'advanced' areas of mathematics to younger learners. The goals here are to use complex but easy tasks as introductions to more advanced topics in math, rather than the standard, sequential process of counting, arithmetic, sets, geometry, then eventually algebra and finally calculus. Quoting: 'Examples of activities that fall into the "simple but hard" quadrant: Building a trench with a spoon (a military punishment that involves many small, repetitive tasks, akin to doing 100 two-digit addition problems on a typical worksheet, as Droujkova points out), or memorizing multiplication tables as individual facts rather than patterns. Far better, she says, to start by creating rich and social mathematical experiences that are complex (allowing them to be taken in many different directions) yet easy (making them conducive to immediate play). Activities that fall into this quadrant: building a house with LEGO blocks, doing origami or snowflake cut-outs, or using a pretend "function box" that transforms objects (and can also be used in combination with a second machine to compose functions, or backwards to invert a function, and so on).' I plan to get my children learning the 'advanced' topics as soon as possible. How about you?"

Child Porn Arrest For Cameron Aide Who Helped Plan UK Net Filters
An anonymous reader writes "A senior aide to David Cameron resigned from Downing Street last month the day before being arrested on allegations relating to child abuse images. Patrick Rock, who was involved in drawing up the government's policy for the large internet firms on online pornography filters, resigned after No 10 was alerted to the allegations. Rock was arrested at his west London flat the next morning. Officers from the National Crime Agency subsequently examined computers and offices used in Downing Street by Rock, the deputy director of No 10's policy unit, according to the Daily Mail, which disclosed news of his arrest."

Walmart Unveils Turbine-Powered WAVE Concept Truck
cartechboy writes "It's no secret that semi trucks use a lot of fuel. Moving that amount of mass along at highway speeds takes a lot of power. But Walmart might have just unveiled the semi truck of the future with its WAVE concept truck. This crazy looking semi features an aerodynamic cab and looks like no other truck on the road. The driver sits in the center of the cab and the steering wheel is flanked by LCD screens instead of conventional gauges. The WAVE concept is powered by a range-extended electric powertrain consisting of a Capstone micro-turbine and an electric motor. To reduce weight the entire truck including the trailer is made of carbon fiber. The 53-foot side panels on the trailer are said to be the first single pieces of carbon fiber that large ever produced. The result? A trailer that weighs around 4,000 pounds less than a conventional one. While Walmart says it has no plans to produce the WAVE concept, one has to wonder if this is a look at what semis of the future will be like."

Ouya CEO Talks Console's Tough First Year, and Ambitious "Ouya Everywhere" Plan
Nerval's Lobster writes "As founder and CEO of the Ouya (pronounced "OOO-yah") game company, Julie Uhrman's mission has been to lure gamers back to their living room televisions. Touch-screen gaming on a smartphone or tablet is nice, she suggests, but a big screen, coupled with the precision of a controller with buttons and analog sticks, offers the best platform for immersive, emotionally engaging experiences. Soon enough, though, you shouldn't need an Ouya console to play Ouya games. Later this week, Uhrman plans to announce 'Ouya Everywhere,' an initiative to bring Ouya games to television sets that aren't connected to Ouya hardware. As a company, Ouya remains vague about just how Ouya Everywhere will work; but in an interview with Slashdot, Uhrman provided a rough idea of what to expect: 'It could be another set-top [box],' she said. 'It could be the TV itself. There's a number of different ways that games can be played on the television, and we're actively exploring all of them.' To be clear, Ouya isn't getting out of the hardware business. The company has promised relatively frequent hardware refreshes, and already upgraded the original Ouya's controller to address early complaints. The next version of the Ouya hardware 'at a minimum will have a higher performing chipset,' she said. 'We have done a lot of work on our controller and we feel like there is even more work to do. Those are the two big things we're focused on.' But while her company builds hardware, Uhrman insists that Ouya is 'really a software company. The largest team inside Ouya is software engineers.' (Ouya has 49 employees, 19 of them engineers.) Ouya arrived with great fanfare in 2012, after a $950,000 Kickstarter campaign met its goal in just eight hours. The fundraiser ended up raising $8.6 million, and Kickstarter backers received their consoles in March 2013."

Physicists Test Symmetry Principle With an Antimatter Beam
Hugh Pickens DOT Com writes "Jon Butterworth has an interesting article at The Guardian about the idea of standpoint-independence in physics and the absence of 'privileged observers.' The ASACUSA experiment at CERN plans to make a beam of antimatter, and measure the energy levels as the beam travels in a vacuum, away from the magnetic fields and away from any annihilating matter. The purpose of the experiment is to test CPT (Charge/Parity/Time) inversion to determine if the universe would look the same if we simultaneously swapped all matter for antimatter, left for right, and backwards in time for forwards in time. In string theory for example it is possible to violate this principle so the ASACUSA people plan to measure those antihydrogen energy levels very precisely. Any difference would mean a violation of CPT inversion symmetry. Physicist Ofer Lahav has some interesting observations in the article about how difficult it is these days for physicists to develop independent points of view on cosmology. 'Having been surrounded by a culture in which communication is seen as generally a good thing, this came as a surprise to me, but it is a very good point,' writes Butterworth. 'We gain confidence in the correctness of ideas if they are arrived at independently from different points of view.'
A good example is the independent, almost simultaneous development of quantum electrodynamics by Richard Feynman, Julian Schwinger and Sin-Itiro Tomonaga. They all three had very different approaches, and Tomonaga in particular was working in wartime Japan, completely cut off from the others. Yet Freeman Dyson was able to prove that the theories each had provided for the quantum behavior of electrons and photons were not only all equally good at describing nature, but were all mathematically equivalent — that is, the same physics, seen from different points of view. Whether we are using thought experiments, antimatter beams, sophisticated instrumentation, or sending spaceships to the outer solar system, Butterworth says the ability for scientists to loosen the constraints of our own point of view is hugely important. 'It is also, I think, closely related to the ability to put ourselves into the place of other people in society and to perceive ourselves as seen by them — to check our privilege, if you like. Imperfect and difficult, but a leap away from a childish self-centeredness and into adulthood.'" -
India Plans Mission To Probe Sun By 2020
An anonymous reader writes "India is planning a mission to probe the Sun before 2020. The nation launched a Moon mission a few years ago and sent a Mars mission late last year. From the article: 'Indian Space Research Organization has lined up over a dozen missions, including its first probe on the Sun, Isro chairman K Radhakrishnan said on Friday. Though, the mission to probe the Sun was already on the cards, the agency now has a clear picture of its plan and had put a timeframe within which it hoped to undertake it, Radhakrishnan said, while addressing students at a private University here. He said the "Aditya" mission to the Sun had been planned between 2017 and 2020.'"

How An Astronaut Nearly Drowned During a Space Walk
Hugh Pickens DOT Com writes "About 44 minutes into a 6.5-hour spacewalk last July, Italian astronaut Luca Parmitano noted that water was building up inside his helmet – the second consecutive spacewalk during which he reported the problem. As Parmitano worked his way back to the air lock, water covered his eyes, filled his ears, disrupted communications, and eventually began to enter his nose, making it difficult for him to breathe. 'I know that if the water does overwhelm me I can always open the helmet,' wrote Parmitano about making it to the airlock. 'I'll probably lose consciousness, but in any case that would be better than drowning inside the helmet.' Later, when crew mates removed his helmet, they found that it contained at least 1.5 quarts of water. In a 122-page report released Wednesday, a mishap investigation board identified a range of causes for the near-tragedy, including organizational causes that carried echoes of accident reports that followed the loss of the shuttles Challenger and Columbia and their crews in 1986 and 2003. Engineers traced the leak to a fan-and-pump assembly that is part of a system that extracts moisture from the air inside the suit and returns it to the suit's water-based cooling system. Contaminants clogged holes that would have carried the water to the cooling system after it was extracted from the air. The water backed up and flowed into the suit's air-circulation system, which sent it into Parmitano's helmet (PDF).
The specific cause of the contamination is still under investigation but investigators also identified deeper causes, one of which involved what some accident-investigation specialists have dubbed the 'normalization of deviance' – small malfunctions that appear so often that eventually they are accepted as normal. In this case, small water leaks had been observed in space-suit helmets for years, despite the knowledge that the water could form a film on the inside of a helmet, fogging the visor or reacting with antifogging chemicals on the visor in ways that irritate eyes. NASA officials are not planning on resuming non-urgent spacewalks before addressing all 16 of the highest priority suggestions from the Mishap Investigation Board. 'I think it's a tribute to the agency that we're not hiding this stuff, that we're actually out trying to describe these things, and to describe where we can get better,' says William Gerstenmaier, associate administrator for NASA's Human Exploration and Operations Mission Directorate. 'I think that's how we prevent Columbias and Challengers.'" -
Indian Space Agency Prototypes Its First Crew Capsule
First time accepted submitter sixsigma1978 writes "India is about to take one small step towards human space flight. Last week the country's space agency unveiled a prototype of its first crew capsule, a 4-meter-high module designed to carry two people into low Earth orbit. The Indian Space Research Organization (ISRO) is planning a test flight for later this year – even though it still awaits government approval and funding for a human space-flight program. The unpiloted capsule will fly on the maiden launch of a new type of rocket that would otherwise have carried a dummy payload."
