Oculus Rift Hardware Requirements Revealed, Linux and OS X Development Halted
Posted by News Fetcher on May 15 '15 at 01:00 PM

By Soulskill from Slashdot's sad-penguin department:
An anonymous reader writes: Oculus has selected the baseline hardware requirements for running their Rift virtual reality headset. To no one's surprise, they're fairly steep: NVIDIA GTX 970 / AMD 290 equivalent or greater, Intel i5-4590 equivalent or greater, and 8GB+ RAM. It will also require at least two USB 3.0 ports and "HDMI 1.3 video output supporting a 297MHz clock via a direct output architecture."

Oculus chief architect Atman Binstock explains: "On the raw rendering costs: a traditional 1080p game at 60Hz requires 124 million shaded pixels per second. In contrast, the Rift runs at 2160×1200 at 90Hz split over dual displays, consuming 233 million pixels per second. At the default eye-target scale, the Rift's rendering requirements go much higher: around 400 million shaded pixels per second. This means that by raw rendering costs alone, a VR game will require approximately 3x the GPU power of 1080p rendering." He also points out that PC graphics can afford a fluctuating frame rate — it doesn't matter too much if it bounces between 30-60fps. The Rift has no such luxury, however.

The last requirement is more onerous: WIndows 7 SP1 or newer. Binstock says their development for OS X and Linux has been "paused" so they can focus on delivering content for Windows. They have no timeline for going back to the less popular platforms.

The Solution To Argentina's Banking Problems Is To Go Cashless
Posted by News Fetcher on May 15 '15 at 12:45 PM

By Soulskill from Slashdot's why-would-you-carry-around-slips-of-paper-and-shards-of-metal-anyway department:
dkatana writes: There is no way back for Argentinian people to trust their own currency. Several governments have used the "Peso/Dollar" exchange to dig into people's savings, reward their friends and limit the freedom of citizens to use other currencies.

Short of Dollarizing the economy again, the only solution for the country is going cashless. People are desperate, and they're looking for alternatives such as mobile payments, Amazon gift cards and Bitcoin to store their savings away from government control. A digital currency could help curb black market exchanges, fight corruption and restore the country's image.

Larson B Ice Shelf In Antarctica To Disintegrate Within 5 Years
Posted by News Fetcher on May 15 '15 at 11:30 AM

By Soulskill from Slashdot's grab-some-popcorn department:
BarbaraHudson writes: A new study (abstract) from NASA scientists predicts an Antarctic ice shelf half the size of Rhode Island will disintegrate around 2020. The shelf has existed for roughly 10,000 years. "Ice shelves are the gatekeepers for glaciers flowing from Antarctica toward the ocean. Without them, glacial ice enters the ocean faster and accelerates the pace of global sea level rise." At its thickest point, the ice shelf remnant is a half kilometer tall, and spans approximately 1,600 square kilometers. "The glaciers' thicknesses and flow speeds changed only slightly in the first couple of years following the 2002 collapse, leading researchers to assume they remained stable. The new study revealed, however, that Leppard and Flask glaciers have thinned by 65-72 feet (20-22 meters) and accelerated considerably in the intervening years. The fastest-moving part of Flask Glacier had accelerated 36 percent by 2012 to a flow speed of 2,300 feet (700 meters) a year."

Rust 1.0 Released
Posted by News Fetcher on May 15 '15 at 10:45 AM

By Soulskill from Slashdot's ironing-out-the-biggest-wrinkles department:
TopSpin writes: Rust 1.0 has arrived, and release parties in Paris, LA and San Francisco are taking place today. From the Rust Programming Language blog: "The current Rust language is the result of a lot of iteration and experimentation. The process has worked out well for us: Rust today is both simpler and more powerful than we originally thought would be possible. But all that experimentation also made it difficult to maintain projects written in Rust, since the language and standard library were constantly changing. The 1.0 release marks the end of that churn. This release is the official beginning of our commitment to stability, and as such it offers a firm foundation for building applications and libraries. From this point forward, breaking changes are largely out of scope (some minor caveats apply, such as compiler bugs)." You can read about specific changes in the changelog.

Posted by News Fetcher on May 15 '15 at 10:00 AM

By Soulskill from Slashdot's another-day-another-breach department:
coondoggie writes: Penn State's College of Engineering has disconnected its network from the Internet in response to two sophisticated cyberattacks – one from a what the university called a "threat actor based in China" – in an attempt to recover all infected systems. The university said there was no indication that research data or personal information was stolen in the attacks, though usernames and passwords had been compromised.

Here Comes the Keurig of Everything
Posted by News Fetcher on May 15 '15 at 09:30 AM

By Soulskill from Slashdot's for-the-lazy-people-who-only-eat-4-things department:
Tekla Perry writes: Keurig made a huge business out of single-serving coffee machines. Now, as more complex machinery shrinks in size and cost, many companies are trying to duplicate that success for other types of food and drink. Startups are introducing the Keurig of cocktails, the Keurig of Jell-O shots, and the Keurig of dinner (it makes stir fries, stews, and risottos). The question is: does having a single- or limited-purpose device make really make sense for consumables that aren't coffee? Counter space is not infinite, and most people want more variety out of their lunches, dinners, and nightcaps than they do for their morning pick-me-up. (Also, let's retire this metaphor before we get a Keurig for cats.)

MenuetOS, an Operating System Written Entirely In Assembly, Hits 1.0
Posted by News Fetcher on May 15 '15 at 08:45 AM

By Soulskill from Slashdot's done-until-it's-more-done department:
angry tapir writes: MenuetOS, a GUI-toting, x86-based operating system written entirely in assembly language that's super-fast and can fit on a floppy disk, has hit version 1.0 — after almost a decade and a half of development. (And yes, it can run Doom). The developers say it's stable on all hardware with which they've tested it. In this article, they talk about what MenuetOS can do, and what they plan for the future. "For version 2.0 we'll mostly keep improving different application classes, which are already present in 1.00. For example, more options for configuring the GUI and improving the HTTP client. The kernel is already working well, so now we have more time to focus on driver and application side."

Biologists Create Self-Healing Concrete
Posted by News Fetcher on May 15 '15 at 08:00 AM

By Soulskill from Slashdot's building-borg-golems department:
Mr.Intel writes: A team of microbiologists from the Delft University of Technology claims to have invented "bioconcrete" — concrete that heals cracks and breaks using bacteria. The goal was to find a type of bacteria that could live inside concrete and also produce small amount of limestone that could re-seal cracks. This is a difficult prospect because concrete is quite dry and strongly alkaline. The bacteria needed to be able to stay alive for years in those conditions before being activated by water. The bacteria also need a food source — simply adding sugar to concrete will make it weak. The scientists used calcium lactate instead, adding biodegradable capsules of it to the concrete mix. "When cracks eventually begin to form in the concrete, water enters and open the capsules. The bacteria then germinate, multiply and feed on the lactate, and in doing so they combine the calcium with carbonate ions to form calcite, or limestone, which closes up the cracks."

ErnieKey writes: A wounded loggerhead turtle showed up in Turkey, with significant damage to its upper and lower jaws. It was taken to the Sea Turtle Research, Rescue and Rehabilitation Center at Pamukkale University (PAU) for help. The PAU team, working with BTech Innovation, was able to make a 3D printed titanium jaw implant for the turtle. The operation was a success, and the patient — the world's first sea turtle to receive a 3D printed implant — is recovering.

How SpaceX and the Quest For Mars Almost Sunk Tesla Motors
Posted by News Fetcher on May 15 '15 at 06:30 AM

By Soulskill from Slashdot's rocket-bucks-versus-car-bucks department:
braindrainbahrain writes: Elon Musk and his rocket company are well known to Slashdottters. This article and book excerpt tell the story of the creation of SpaceX and how it almost sank Musk's other company, Tesla Motors. Musk recalls, "I could either pick SpaceX or Tesla or split the money I had left between them. That was a tough decision. If I split the money, maybe both of them would die. If I gave the money to just one company, the probability of it surviving was greater, but then it would mean certain death for the other company." But then, at the last moment, years of work at SpaceX finally paid off: "[O]n Dec. 23, 2008, SpaceX received a wonderful shock. The company won a $1.6 billion contract for 12 NASA resupply flights to the space station. Then the Tesla deal ended up closing successfully, on Christmas Eve, hours before Tesla would have gone bankrupt. Musk had just a few hundred thousand dollars left and could not have made payroll the next day." Also, it turns out the inspiration for SpaceX was the idea of sending mice to Mars.

College Board Puts Code.org In Charge of AP CS Program
Posted by News Fetcher on May 15 '15 at 05:45 AM

By Soulskill from Slashdot's must-pass-recruitment-test department:
theodp writes: "The College Board," reports GeekWire, "is endorsing Code.org as a coursework and teacher training provider for its upcoming AP Computer Science Principles course and will help Code.org fund the teacher training work required to establish new computer science classes." So what's the catch? "Schools that commit to using the [new] PSAT [8/9 assessment] to identify middle school students who have potential for success in computer science will be eligible to receive curriculum, training, and funding for programming classes." The organization is bankrolled by some of tech's wealthiest leaders and their corporations. Code.org board member Brad Smith, Microsoft's General Counsel, proposed the idea of "producing a crisis" to advance Microsoft's "two-pronged" National Talent Strategy to increase K-12 CS education and the number of H-1B visas. Just months thereafter, nonprofit organizations Code.org and Mark Zuckerberg's FWD.us, which is lobbying for H-1B reform, were born.

Kepler Observes Neptune Dancing With Its Moons
Posted by News Fetcher on May 15 '15 at 05:00 AM

By Soulskill from Slashdot's you-put-your-right-moon-in,-you-take-your-right-moon-out department:
New submitter Liquid Tip writes: NASA's K2 mission has the capability to stare continuously at a single field of stars for months at time. A new video shows K2 observations spanning 70 days from November, 2014 through January, 2015 reduced to a time-lapse of 34 seconds. During this time, we see some distant members of our Solar System passing through the K2 field-of-view. This includes some asteroids and the giant outer planet Neptune, which appears at day 15. A keen-eyed observer will also notice an object circling Neptune: its large moon, Triton, which orbits every 5.8 days. The fainter moon Nereid can be seen tracing Neptune's motion.

Galaxies Die By Slow "Strangulation"
Posted by News Fetcher on May 15 '15 at 04:30 AM

By samzenpus from Slashdot's if-you-gotta-go-you-gotta-go department:
HughPickens.com writes: BBC reports that results of a study of the spectrum of light emitted by 23,000 red, passive galaxies and 4,000 blue, star-forming ones shows that when galaxies stop making stars, their death is usually a slow process that chokes them of the necessary cool gases over about four billion years. Astronomers surveyed thousands of galaxies, living and dead, to assess whether the transition is rapid or slow. In the dead galaxies they detected high levels of metals, which build up during star formation and point to a slow strangulation process. "Metals are a powerful tracer of the history of star formation: the more stars that are formed by a galaxy, the more metal content you'll see," says Dr Yingjie Peng. "So looking at levels of metals in dead galaxies should be able to tell us how they died."

A Plan On How To Stop Sexism In Science
Posted by News Fetcher on May 15 '15 at 03:30 AM

By samzenpus from Slashdot's working-it-out department:
StartsWithABang writes: If there's nothing else that science has to offer, it's this elegant notion: that anyone, anywhere, at anytime, can investigate and uncover the mysteries and workings of the Universe simply by asking it the right questions in the right ways, listening to its answers, and putting the pieces together for themselves. Anyone can do it. Only, for various and sundry reasons, not everyone gets to do it. Some people don't have the economic ability, some don't have the sustained drive or interest, and some simply can't cut the mustard. But some people — some really, really good people — are driven from their passions for a sad, simple and completely unnecessary fact: that they were treated in unacceptable ways that they refused to just accept. And in a great many cases, that unacceptable treatment came simply because of their gender. Sexism sometimes looks like what you expect, and sometimes not. Here's one opinion on what we can all do about it to create the world we really want: where science really is for everyone.

Scientists Discover First Warm-Blooded Fish
Posted by News Fetcher on May 15 '15 at 01:45 AM

By samzenpus from Slashdot's keeping-it-warm department:
sciencehabit writes: The opah lives in the dark, chilly depths of the world's oceans, using heated blood to keep warm. It's the first fish found to be fully warm-blooded. Certain sharks and tuna can warm regions of their body such as swimming muscles and the brain but must return to the surface to protect vital organs from the effects of the cold. The opah on the other hand, generates heat from its pectoral muscles, and conserves that warmth thanks to body fat and the special structure of its gills. “It’s a remarkable adaptation for a fish,” says Diego Bernal, a fish physiologist at the University of Massachusetts, Dartmouth.

Are We Entering a "Golden Age of Quantum Computing Research"?
Posted by News Fetcher on May 14 '15 at 11:15 PM

By samzenpus from Slashdot's best-of-days department:
Lashdots writes: Last month, an elite team at IBM Research team announced an advance in quantum computing: it had built a four-qubit square lattice of superconducting qubits, roughly one-quarter-inch square, that was capable of detecting and measuring the two types of quantum computing errors (bit-flip and phase-flip). Previously, it was only possible to address one type of quantum error or the other. The next step is to correct quantum errors.

In a blog post, Mark Ritter, who oversees scientists and engineers at IBM's T.J. Watson Research Laboratory, wrote: "I believe we're entering what will come to be seen as the golden age of quantum computing research." His team, he said, is "on the forefront of efforts to create the first true quantum computer." But what would that mean, and what other big next steps are there?

Kepler's "Superflare" Stars Sport Huge, Angry Starspots
Posted by News Fetcher on May 14 '15 at 08:45 PM

By samzenpus from Slashdot's a-thousand-different-kinds-of-angry department:
astroengine writes: Astronomers studying stars like our sun that are known to generate powerful "superflares" have also discovered that these superflares are likely associated with monster "starspots." In 2012, using Kepler Space Telescope data — which is usually associated with the detection of exoplanets as they drift (or transit) in front of their host stars — astronomers were able to identify several hundred superflare events on a number of sun-like stars. These gargantuan events kicked out flares 10-10,000 times more energy than our sun is able to muster. Keeping in mind that these stars are sun-like stars, what makes them such superflare powerhouses? Why is our sun such a featherweight in comparison? In an effort to understand the dynamics of superflare stars and perhaps answer these questions, astronomers from Kyoto University, University of Hyogo, the National Astronomical Observatory of Japan (NAOJ) and Nagoya University turned to the High Dispersion Spectrograph on the Subaru Telescope, located atop Mauna Kea in Hawaii, to carry out spectroscopic measurements of 50 of Kepler's superflare targets. And they found that all the superflare stars possessed huge starspots that completely dwarf our sun's sunspots.
