What Would Have Happened If Philae Were Nuclear Powered? 473

Posted by samzenpus
from the still-going dept.
StartsWithABang writes After successfully landing on a comet with all 10 instruments intact, but failing to deploy its thrusters and harpoons to anchor onto the surface, Philae bounced, coming to rest in an area with woefully insufficient sunlight to keep it alive. After exhausting its primary battery, it went into hibernation, most likely never to wake again. We'll always be left to wonder what might have been if it had functioned optimally, and given us years of data rather than just 60 hours worth. The thing is, it wouldn't have needed to function optimally to give us years of data, if only it were better designed in one particular aspect: powered by Plutonium-238 instead of by solar panels.

Elusive Dark Matter May Be Detected With GPS Satellites 67

Posted by Soulskill
from the when-they're-not-busy-telling-you-how-far-you-are-from-a-starbucks dept.
An anonymous reader writes: Two researchers say time disparities identified through the network of satellites that make up our modern GPS infrastructure can help detect dark matter. In a paper in the online version of the scientific journal Nature Physics, they write that dark matter may be organized as a large gas-like collection of topological defects, or energy cracks. "We propose to detect the defects, the dark matter, as they sweep through us with a network of sensitive atomic clocks. The idea is, where the clocks go out of synchronization, we would know that dark matter, the topological defect, has passed by." Another reader adds this article about research into dark energy: The particles of the standard model, some type of dark matter and dark energy, and the four fundamental forces. That's all there is, right? But that might not be the case at all. Dark energy may not simply be the energy inherent to space itself, but rather a dynamical property that emerges from the Universe: a sort of fifth force. This is speculation that's been around for over a decade, but there hasn't been a way to test it until now. If this is the case, it may be accessible and testable by simply using presently existing vacuum chamber technology

NVIDIA SHIELD Tablet Android Lollipop Update Performance Explored 57

Posted by timothy
from the stats-and-figures dept.
MojoKid writes Last week, NVIDIA offered information regarding its Android Lollipop update for the SHIELD Tablet and also revealed a new game bundle for it. This week, NVIDIA gave members of the press early access to the Lollipop update and it will also be rolling out to the general public sometime later today. Some of the changes are subtle, but others are more significant and definitely give the tablet a different look and feel over the original Android KitKat release. Android Lollipop introduces a new "material design" that further flattens out the look of the OS. Google seems to have taken a more minimalist approach as everything from the keyboard to the settings menus have been cleaned up considerably. Many parts of the interface don't have any markings except for the absolute necessities. While the OS definitely feels more fluid and responsive, the default look isn't always better, depending on your personal view. The app tray for example has a plain, white background which looks kind of jarring if you've using a colorful background. And finding the proper touch points for things like a settings menu or clearing notifications isn't always clear. Performance-wise, NVIDIA's Shield Tablet showed significantly better performance on Lollipop for general compute tasks in benchmarks like Mobile XPRT but lagged behind Kit Kat in graphics performance slightly, which could be attributed to driver optimization.

Intel Announces Major Reorg To Combine Mobile and PC Divisions 75

Posted by Soulskill
from the goes-together-like-peanut-butter-and-motor-oil dept.
MojoKid writes: For the past year, Intel has pursued what's known as a "contra-revenue" strategy in its mobile division, where product is deliberately sold at a loss to win market share and compete effectively. This has led to a huge rise in tablet shipments, but heavy losses inside Intel's mobile division. Today, the company announced that it would take steps to fold its mobile and conventional processors into a single operating division. While this helps shield the mobile segment from poor short-term results, it also reflects the reality that computing is something users now do across a wide range of devices and multiple operating systems. Intel may not have hit anything like the mobile targets it set out years ago, but long-term success in laptops, tablets, and smartphones remains integral to the company's finances. Desktops and conventional laptops are just one way people compute today and Intel needs to make certain it has a robust long-term presence in every major computing market.

Comment: Small sample sizes, and Correlation IS causation (Score 5, Funny) 243

If you like to use sample sizes that are too small, then I would like to interest you in another useful technique.

Correlation is causation.

For example:

The tides cause the moon. The correlation proves it.

Similarly, murder rates are higher in the summer, and ice cream sales are higher in summer months. Therefore ice cream causes murder.

I hope that was helpful.

Sweden Considers Adding "Sexism" Ratings To Video Games 635

Posted by samzenpus
from the including-everyone dept.
An anonymous reader writes A government-funded agency in Sweden is considering creating special labels for video games based on whether or not the games' portrayals of women are sexist. From the article: "Avoiding sexism and gender stereotypes in video games produced in Sweden will become a key goal for the association, which has been given a 272,000 kronor ($36,672) grant by Sweden's government-funded innovation agency, Vinnova. Inspired by the Bechdel test, which looks at whether fictional films or books feature at least two women talking about a topic other than men, Dataspelsbranchen will work with several game developers to analyze how Swedish video games portray female characters and gender issues.

Comcast Kisses-Up To Obama, Publicly Agrees On Net Neutrality 257

Posted by timothy
from the wormtongues-all-around dept.
MojoKid writes Comcast is one of two companies to have earned Consumerist's "Worst Company in America" title on more than one occasion and it looks like they're lobbying for a third title. That is, unless there's another explanation as to how the cable giant can claim (with straight face) that it's in agreement with President Barack Obama for a free and open Internet. Comcast issued a statement of its own saying they back the exact same things, it just doesn't want to go the utility route. Comcast went on to list specific bullet points that they're supposedly in wholehearted agreement with, such as: Free and open Internet. We agree — and that is our practice. No blocking. We agree — and that is our practice. No throttling. We agree — and that is our practice. Increased transparency. We agree — and that is our practice. No paid prioritization. We agree — and that is our practice. Really? Comcast conveniently fails to address the giant elephant in the room whose name is Netflix. Earlier this year, Netflix begrudgingly inked a multi-year deal with Comcast in which the streaming service agreed to pay a toll to ensure faster delivery into the homes of Comcast subscribers, who prior to the deal had been complaining of frequent buffering and video degradation when watching content on Netflix. Comcast would undoubtedly argue that it's not a paid fast lane, but it's hard to see the deal as anything other than that.

Entrepreneur Injects Bitcoin Wallets Into Hands 77

from the heirs-are-not-amused dept.
wiredmikey writes A Dutch entrepreneur has had two microchips containing Bitcoin injected into his hands to help him make contactless payments. The chips, enclosed in a 2mm by 12mm capsule of "biocompatible" glass, were injected using a special syringe and can communicate with devices such as Android smartphones or tablets via NFC. "What's stored on the microchips should be seen as a savings account rather than a current account," Martijn Wismeijer, co-founder of MrBitcoin said. "The payment device remains the smartphone, but you transfer funds from the chips." The chips are available on the Internet, sold with a syringe for $99, but Wismeijer suggested individuals should find a specialist to handle the injection to avoid infections.

An Applied Investigation Into Graphics Card Coil Whine 111

Posted by timothy
from the like-y'do dept.
jones_supa writes We all are aware of various chirping and whining sounds that electronics can produce. Modern graphics cards often suffer from these kind of problems in form of coil whine. But how widespread is it really? Hardware Canucks put 50 new graphics cards side-by-side to compare them solely from the perspective of subjective acoustic disturbance. NVIDIA's reference platforms tended to be quite well behaved, just like their board partners' custom designs. The same can't be said about AMD since their reference R9 290X and R9 290 should be avoided if you're at all concerned about squealing or any other odd noise a GPU can make. However the custom Radeon-branded SKUs should usually be a safe choice. While the amount and intensity of coil whine largely seems to boil down to luck of the draw, at least most board partners are quite friendly regarding their return policies concerning it.

Like others I found the headline confusing. I read it as "Researchers are predicting the use of Wikipedia as a vector for the spread of disease". This may mean that:

  • Disinformation and ignorance are diseases.
  • Memes and computer viruses are diseases.
  • Wilipedia contains information that leads to depression.
  • Instructions on Wikipedia lead to substance abuse.
  • This is getting entertaining, fill in your own reason here.

How 4H Is Helping Big Ag Take Over Africa 377

Posted by samzenpus
from the white-elephant dept.
Lasrick writes 4H is in Africa, helping to distribute Big Ag products like DuPont's Pioneer seeds through ostensibly good works aimed at youth. In Africa, where the need to produce more food is especially urgent, DuPont Pioneer and other huge corporations have made major investments. But there are drawbacks: "DuPont's nutritious, high-yielding, and drought-tolerant hybrid seed costs 10 times as much. While Ghanaians typically save their own seeds to plant the next year, hybrid seeds get weaker by the generation; each planting requires another round of purchasing. What's more, says Devlin Kuyek, a researcher with the sustainable-farming nonprofit Genetic Resources Action International, because hybrid seeds are bred for intensive agriculture, they typically need chemicals to thrive."

Intel Claims Chip Suppliers Will Flock To Its Mobile Tech 91

Posted by samzenpus
from the most-wanted dept.
MojoKid writes It has been over six years since Intel first unveiled its Atom CPUs and detailed its plans for new, ultra-mobile devices. The company's efforts to break into smartphone and tablet sales, while turning a profit, have largely come to naught. Nonetheless, company CEO Brian Krzanich remains optimistic. Speaking to reporters recently, Krzanich opined that the company's new manufacturing partners like Rockchip and Spreadtrum would convert entirely to Intel architectures within the next few years. Krzanich has argued that with Qualcomm and MediaTek dominating the market, it's going to be tougher and tougher for little guys like Rockchip and Spreadtrum to compete in the same spaces. There's truth to that argument, to be sure, but Intel's ability to offer a competitive alternative is unproven. According to a report from JP Morgan, Intel's cost-per-wafer is currently estimated as equivalent to TSMC's average selling price per wafer — meaning TSMC is making money well below Intel's break-even. Today, Intel is unquestionably capable of building tablet processors that offer a good overall experience but the question of what defines a "good" experience is measured in its similarity to ARM. It's hard to imagine that Intel wants to build market share as an invisible partner, but in order to fundamentally change the way people think about Intel hardware in tablets and smartphones, it needs to go beyond simply being "as good" and break into territory that leaves people asking: "Is the ARM core just as good as the Intel chip?"

AT&T To "Pause" Gigabit Internet Rollout Until Net Neutrality Is Settled 306

"We can't go out and just invest that kind of money, deploying fiber to 100 cities other than these two million [covered by the DirecTV deal], not knowing under what rules that investment will be governed," AT&T Chief Randall Stephenson said during an appearance at a Wells Fargo conference, according to a transcript provided by AT&T. "And so, we have to pause, and we have to just put a stop on those kind of investments that we're doing today."

Data Center Study Reveals Top 5 SMART Stats That Correlate To Drive Failures 138

Posted by samzenpus
from the about-to-go dept.
Lucas123 writes Backblaze, which has taken to publishing data on hard drive failure rates in its data center, has just released data from a new study of nearly 40,000 spindles revealing what it said are the top 5 SMART (Self-Monitoring, Analysis and Reporting Technology) values that correlate most closely with impending drive failures. The study also revealed that many SMART values that one would innately consider related to drive failures, actually don't relate it it at all. Gleb Budman, CEO of Backblaze, said the problem is that the industry has created vendor specific values, so that a stat related to one drive and manufacturer may not relate to another. "SMART 1 might seem correlated to drive failure rates, but actually it's more of an indication that different drive vendors are using it themselves for different things," Budman said. "Seagate wants to track something, but only they know what that is. Western Digital uses SMART for something else — neither will tell you what it is."
