Nerval's Lobster writes "Research scientists could learn an important thing or two from computer scientists, according to a new study (abstract) showing that data underpinning even groundbreaking research tends to disappear over time. Researchers also disappear, though more slowly and only in terms of the email addresses and the other public contact methods that other scientists would normally use to contact them. Almost all the data supporting studies published during the past two years is still available, as are at least some of the researchers, according to a study published Dec. 19 in the journal Current Biology. The odds that supporting data is still available for studies published between 2 years and 22 years ago drops 17 percent every year after the first two. The odds of finding a working email address for the first, last or corresponding author of a paper also dropped 7 percent per year, according to the study, which examined the state of data from 516 studies between 2 years and 22 years old. Having data available from an original study is critical for other scientists wanting to confirm, replicate or build on previous research – goals that are core parts of the evolutionary, usually self-correcting dynamic of the scientific method on which nearly all modern research is based. No matter how invested in their own work, scientists appear to be 'poor stewards' of their own work, the study concluded."
ckwu writes "The vast real estate of windows in office buildings and skyscrapers could be a fruitful field for harvesting solar energy—if lightweight solar cells could be made with a high enough conversion efficiency and appealing aesthetics. Now researchers at Oxford University report semitransparent solar cells that might do the trick. The team made solar cells using a perovskite, a class of mineral-like materials that have properties similar to inorganic semiconductors and show sunlight-to-electricity conversion efficiencies of more than 15%. The team deposited a thin film of perovskite onto glass so that the material formed tiny crystalline islands. The islands absorb photons and convert them to electrons, while light striking the empty areas passes through. The result was a semitransparent solar cell with a grayish tint."
cartechboy writes "It looks like Elon Musk and Tesla Motors find themselves in another PR war over the cause of a fire involving a Tesla Model S. Authorities in Irvine, CA are currently investigating the reason for a fire in a garage that, yes, contained a Tesla Model S. While the actual cause of the fire remains unknown, Tesla Motors and the Orange County Fire Authority are already publicly disputing possible causes, thought to center around the Tesla charging system. Tesla says the fire was not caused by any part of the car nor its charging system, reports Reuters. For what its worth — we've seen a version of this movie before. In 2011, investigators determined that a garage fire that destroyed a Chevrolet Volt had started away from the car, later spreading to engulf and destroy the car."

waderoush writes "One of the problems that kept PR2, a two-armed humanoid robot developed by Menlo Park, CA-based Willow Garage, from succeeding commercially was its $400,000 price tag. But as it turned out, only a handful of the 40 or so universities that own PR2s ever developed applications that use both arms. That's one of the reasons why UBR-1, a mobile manipulator robot from Willow Garage spinoff Unbounded Robotics, has only one arm. And that, along with many other engineering decisions and technology improvements, will allow the startup to sell its robot for just $35,000 (it's designed for materials-handling tasks in places like warehouses, elder care facilities, and supermarkets). 'With robots, feature creep is so much more present than in some other fields,' says Unbounded co-founder and CEO Melonee Wise. 'There is always this desire to make a Swiss Army knife. But you have to make compromises, and those compromises directly impact the capabilities as well as the cost of the robot.' One roboticist told Unbounded: 'Your robot is so inexpensive that if I needed to have a second arm, I'd just buy a second robot.'"

The new research out of Johns Hopkins University confirms both situations are possible. All it takes are a few tweaks to the camera's firmware."
hessian writes "According to a news release from Purdue University, 'Researchers are developing computers capable of "approximate computing" to perform calculations good enough for certain tasks that don't require perfect accuracy, potentially doubling efficiency and reducing energy consumption. "The need for approximate computing is driven by two factors: a fundamental shift in the nature of computing workloads, and the need for new sources of efficiency," said Anand Raghunathan, a Purdue Professor of Electrical and Computer Engineering, who has been working in the field for about five years. "Computers were first designed to be precise calculators that solved problems where they were expected to produce an exact numerical value. However, the demand for computing today is driven by very different applications. Mobile and embedded devices need to process richer media, and are getting smarter – understanding us, being more context-aware and having more natural user interfaces. ... The nature of these computations is different from the traditional computations where you need a precise answer."' What's interesting here is that this is how our brains work."
An anonymous reader writes "We tend to take things like household appliances and other automation for granted, but as O'Reilly's Mike Loukides puts it: 'The Future Is All Robots. But Will We Even Notice? We've watched the rising interest in robotics for the past few years. It may have started with the birth of FIRST Robotics competitions, continued with the iRobot and the Roomba, and more recently with Google's driverless cars. But in the last few weeks, there has been a big change. Suddenly, everybody's talking about robots and robotics. ... I have no doubt that Google’s robotics team is working on something amazing and mind-blowing. Should they succeed, and should that success become a product, though, whatever they do will almost certainly fade into the woodwork and become part of normal, everyday reality. And robots will remain forever in the future. We might have found Rosie, the Jetsons’ robotic maid, impressive. But the Jetsons didn’t.'"

Unfortunately the technical documentation does not seem to be available yet, but previous comments indicate that it will be a barrel plug of some kind." I wish they'd push a yank-resistant and positive-connecting plug along the lines of Apple's MagSafe.

SonicSpike writes "Light bulb manufacturers will cease making traditional 40 and 60-watt light bulbs — the most popular in the country — at the start of 2014. This comes after the controversial phasing out of incandescent 75 and 100-watt light bulbs at the beginning of 2013. In their place will be halogen bulbs, compact fluorescent bulbs, LED bulbs and high efficiency incandescents — which are just regular incandescents that have the filament wrapped in gas. All are significantly more expensive than traditional light bulbs, but offer significant energy and costs savings over the long run. (Some specialty incandescents — such as three-way bulbs — will still be available.) ... The rules were signed into law by President George W. Bush in 2007. They are designed to address gross inefficiencies with old light bulbs — only 10% of the energy they use is converted into light, according to the Environmental Protection Agency, which has a handy fact sheet about the changes. The rest is wasted as heat. But the rules have drawn fire from a number of circles — mainly conservatives and libertarians who are unhappy about the government telling people what light bulbs they can use. They argue that if the new ones really are so good, people will buy them on their own without being forced to do so."

New submitter ghack writes "NuScale power, a small nuclear power company in Corvallis Oregon, has won a Department of Energy grant of up to $226 million dollars to enable deployment of their small modular reactor. The units would be factory built in the United States, and their small size enables a number of potential niche applications. NuScale argues that their design includes a number of unique passive safety features: 'NuScale's 45-megawatt reactor, which can be grouped with others to form a utility-scale plant, would sit in a 5 million-gallon pool of water underground. That means it needs no pumps to inject water to cool it in an emergency - an issue ... highlighted by Japan's crippled Fukushima plant.' This was the second of two DOE small modular reactor grants; the first was awarded to Babcock and Wilcox, a stalwart in the nuclear industry."

For the rest of us, Redmonk's Stephen O'Grady distilled the pricing trends down to this: 'HP offers the best compute value and instance sizes for the dollar. Google offers the best value for memory, but to get there it appears to have sacrificed compute. AWS is king in value for disk and it appears no one else is even trying to come close. Microsoft is taking the 'middle of the road,' never offering the best or worst pricing.'"
cartechboy writes "How many Nissan Leafs does it take to power an office building? The answer, it turns out, is six. Nissan is the latest Japanese automaker to explore electric "vehicle-to-building" setups, this time with impressive results. The company started testing its latest system at the Nissan Advanced Technology Center in Atsugi City, Japan, during the summer. It found that just six Leafs plugged in to the building's power supply allowed it to cut peak-hour electricity use by 2 percent. Annualized, that's a savings of half a million yen (about $4,800 US) in electricity costs. How it works: The building pulls electricity from the plugged-in vehicles during peak-use hours, when power is most expensive, and then sends the power back to recharge the cars when grid prices fall. Nissan says the system is set up to ensure the cars are fully charged by the end of the workday. (Is this a devious secret way to make sure workers stay until a certain time?) Next up: Why not just do this using batteries--never mind the cars?"

An anonymous reader writes "There is a lot of advice about backing up data, but it seems to boil down to distributing it to several places (other local or network drives, off-site drives, in the cloud, etc.). We have hundreds of thousands of family pictures and videos we're trying to save using this advice. But in some sparse searching of our archives, we're seeing bitrot destroying our memories. With the quantity of data (~2 TB at present), it's not really practical for us to examine every one of these periodically so we can manually restore them from a different copy. We'd love it if the filesystem could detect this and try correcting first, and if it couldn't correct the problem, it could trigger the restoration. But that only seems to be an option for RAID type systems, where the drives are colocated. Is there a combination of tools that can automatically detect these failures and restore the data from other remote copies without us having to manually examine each image/video and restore them by hand? (It might also be reasonable to ask for the ability to detect a backup drive with enough errors that it needs replacing altogether.)"
Nerval's Lobster writes "The so-called "Internet of Things" has rapidly become a buzzword du jour, with everyone from tech-giant CEOs to analysts rhapsodizing about the benefits of connecting everyday objects and appliances to the Web. Despite all the hype, some significant obstacles remain to fulfilling that vision of a massively interconnected world. For starters, all the players involved need to agree on shared frameworks for building compatible software—something that seems well on its way with the just-announced AllSeen Alliance, which includes Sharp, Cisco, LG Electronics, Qualcomm, Panasonic, D-Link, and the Linux Foundation (among many others). In theory, the AllSeen Alliance's combined software and engineering resources will result in open-source systems capable of seamless communication with one another. The Alliance will base its initial framework on AllJoyn, an open-source framework first developed by Qualcomm and subsequently elaborated upon by other firms. Applications and services that support AllJoyn can communicate "regardless of manufacturer or operating system and without the need for Internet access," according to the Alliance, whose Website offers the initial codebase. "Open source is the ideal, neutral staging area for collaboration that can provide the interoperability layer needed to make the Internet of Everything a reality," read a Dec. 10 note on the Linux Foundation's official blog. "When everyone jointly develops and uses the same freely available code, companies can develop innovative services on top of it and get them to market faster." However, not all companies interested in exploring the Internet of Things have joined the AllSeen Alliance. For example, Intel isn't a partner, despite having recently created a new division, the Internet of Things Solutions Group, to explore how to best make devices and networks more connected and aware."

A team of researchers led by Associate Professor Joshua Pearce at the Michigan Technological University developed the firmware and the plans for the printer and have made it available freely. The open source 3D printer is definitely a huge leap forward as the starting price of commercial counterparts is around £300,000. Pearce claimed that their technology will not only allow smaller companies and start-ups to build inexpensive prototypes, but it will allow other scientists and researchers to build tools and objects required for their research without having to shell out thousands, and could be used to print parts for machines such as windmills." It's a modified RepRap; looks like we're getting closer to the RepRap being able to print all of its parts.

In three years, 2017, nearly 45% of all the servers leaving manufacturers will be bought by cloud providers. The shift is slowing the purchase of server sales to enterprise IT. The increased use of SaaS is a major reason for the market shift, but so is virtualization to increase server capacity. Data center consolidations are eliminating servers as well, along with the purchase of denser servers capable of handling larger loads. The increased use of cloud-based providers is roiling the server market, and is expected to help send server revenue down 3.5% this year, according to IDC."
Hugh Pickens DOT Com writes "Lindsay Abrams reports at Salon that the Obama administration is offering wind farms 30 years of leeway to kill and harm bald and golden eagles. The new regulations, which were requested by the wind industry, will provide companies that seek a permit with legal protection, preventing them from having to pay penalties for eagle deaths (PDF). An investigation by the Associated Press earlier this year documented the illegal killing of eagles around wind farms, the Obama administration's reluctance to prosecute such cases and its willingness to help keep the scope of the eagle deaths secret. President Obama has championed the pollution-free energy, nearly doubling America's wind power in his first term as a way to tackle global warming. Scientists say wind farms in 10 states have killed at least 85 eagles since 1997, with most deaths occurring between 2008 and 2012, as the industry was greatly expanding. Most deaths — 79 — were golden eagles that struck wind turbines. However the scientists said their figure is likely to be 'substantially' underestimated, since companies report eagle deaths voluntarily and only a fraction of those included in their total were discovered during searches for dead birds by wind-energy companies. The National Audubon Society said it would challenge the decision."
stox tips an article from Nobel Week Dialogue about the biggest problem of the nuclear power industry: it's not fun anymore. The author, Ashutosh Jogalekar, expands upon this quote from Freeman Dyson: "The fundamental problem of the nuclear industry is not reactor safety, not waste disposal, not the dangers of nuclear proliferation, real though all these problems are. The fundamental problem of the industry is that nobody any longer has any fun building reactors. Sometime between 1960 and 1970 the fun went out of the business. The adventurers, the experimenters, the inventors, were driven out, and the accountants and managers took control. The accountants and managers decided that it was not cost effective to let bright people play with weird reactors." Jogalekar adds, "For any technological development to be possible, the technology needs to drive itself with the fuel of Darwinian innovation. It needs to generate all possible ideas – including the weird ones – and then fish out the best while ruthlessly weeding out the worst. ... Nothing like this happened with nuclear power. It was a technology whose development was dictated by a few prominent government and military officials and large organizations and straitjacketed within narrow constraints. ... The result was that the field remained both scientifically narrow and expensive. Even today there are only a handful of companies building and operating most of the world's reactors. To reinvigorate the promise of nuclear power to provide cheap energy to the world and combat climate change, the field needs to be infused with the same entrepreneurial spirit that pervaded the TRIGA design team and the Silicon Valley entrepreneurs."
MojoKid writes "A leaked Intel roadmap for solid state storage technology suggests the company is pushing ahead with its plans to introduce new high-end drives based on cutting-edge NAND flash. It's significant for Intel to be adopting 20nm NAND in its highest-end data center products, because of the challenges smaller NAND nodes present in terms of data retention and reliability. Intel introduced 20nm NAND lower in the product stack over a year ago, but apparently has waited till now to bring 20nm to the highest end. Reportedly, next year, Intel will debut three new drive families — the SSD Pro 2500 Series (codenamed Temple Star), the DC P3500 Series (Pleasantdale) and the DC P3700 Series (Fultondale). The Temple Star family uses the M.2 and M.25 form factors, which are meant to replace the older mSATA form factor for ultrabooks and tablets. The M.2 standard allows more space on PCBs for actual NAND storage and can interface with PCIe, SATA, and USB 3.0-attached storage in the same design. The new high-end enterprise drives, meanwhile, will hit 2TB (up from 800GB), ship in 2.5" and add-in card form factors, and offer vastly improved performance. The current DC S3700 series offers 500MBps writes and 460MBps reads. The DC P3700 will increase this to 2800MBps read and 1700MBps writes. The primary difference between the DC P3500 and DC P3700 families appears to be that the P3700 family will use Intel's High Endurance Technology (HET) MLC, while the DC P3500 family sticks with traditional MLC."

cartechboy writes "Does the Tesla Model S suck down power even when the car is switched off? Recently, a tweet to Elon Musk with an article saying so sparked the Tesla CEO's attention. He tweeted that it wasn't right and that he'd look into the situation. Then a few hours later, he tweeted that the issue had to do with a bad 12-volt battery. Turns out Tesla had already called the owner of the affected car and sent a service tech to his house to replace that battery — and also install a newer build of the car's software. Now it appears the 'Vampire Draw' has been slain. The car went from using 4.5 kWh per day while turned off to a mere 1.1 kWh. So, it seems to be solved, but Tesla may either need to fix some software, or start sending a few new 12-volt batteries out to the folks still experiencing the issue."
Kristian vonBengtson writes "Wanna build your own space capsule capable of doing an atmospheric re-entry on a suborbital mission? Well, here are some production hints and a visual guide." The initial stages begin with sketches on paper before moving to 3D design software. He writes, "A whole bunch of sketches were done to get some kind of initial idea of the size, subsystems layout and how to actually produce the capsule while keeping an open structure for further development and potential changes. One of the main concerns was the small size and the ability to easy install and replace avionics. This led to the decision that all external side panels will have to accommodate being taken on and off – no welding, only on the main structure." Afterward, he moves on to show the final metal cuts and how the pieces are put together via bolts and welding.
itwbennett writes "Broadcom Chairman and CTO Henry Samueli has some bad news for you: Moore's Law isn't making chips cheaper anymore because it now requires complicated manufacturing techniques that are so expensive they cancel out the cost savings. Instead of getting more speed, less power consumption and lower cost with each generation, chip makers now have to choose two out of three, Samueli said. He pointed to new techniques such as High-K Metal Gate and FinFET, which have been used in recent years to achieve new so-called process nodes. The most advanced process node on the market, defined by the size of the features on a chip, is due to reach 14 nanometers next year. At levels like that, chip makers need more than traditional manufacturing techniques to achieve the high density, Samueli said. The more dense chips get, the more expensive it will be to make them, he said."
£10 BlinkStick kit (£15 pre-assembled), you get a programmable multi-color LED that's about the size of a flash memory key. Deceptively simple -- it's essentially one giant pixel, after all, which might not sound exciting when you have millions of them on a dense display surface. But that LED light is something you can use as a signal for alarms, or to tell you that you have a message from one app while another is at full-screen, or practically anything else that you can devise software to notice and react to. I get the sense that Juskevicius would prefer that people get the kit version, to help spur interest in actually soldering some hardware rather than just plugging it in. If you're allergic to paying in other than U.S. dollars, the BlinkStick is also available from Adafruit Industries. Watch the video below to see it in action.

The system works by converting AC to a higher frequency and voltage and sending it to a receiver that resonates at the same frequency, making it possible to transfer the power safely via magnetic field. Intel and Foxconn are also investors, and you might see them license the tech soon as well."

Ernesto Ford, the arresting officer, pointed out, 'theft is a theft,' which was his argument for arresting Mr. Kamooneh. Considering the cost of the infraction, it does not seem a reasonable decision when considering how much this will cost the state in legal funds. Does this mean anyone charging a laptop or cell phone will be charged with theft as well?"
nk497 writes "Consumer hard drives don't fail any more often than enterprise-grade hardware — despite the price difference. That's according to online storage firm Backblaze, which uses a mix of both types of drive. It studied its own hardware, finding consumer hard-drives had a failure rate of 4.2%, while enterprise-grade drives failed at a rate of 4.6%. CEO Gleb Budman noted: 'It turns out that the consumer drive failure rate does go up after three years, but all three of the first three years are pretty good,' he notes. 'We have no data on enterprise drives older than two years, so we don't know if they will also have an increase in failure rate. It could be that the vaunted reliability of enterprise drives kicks in after two years, but because we haven't seen any of that reliability in the first two years, I'm skeptical.'"
sfcrazy writes "The creator of the most sought after 'Android' of the world has been secretly working on creating a robotics division within Google. The search engine giant has acquired over seven robotics companies recently to create the robotics unit which is being headed by none other than Andy Rubin himself. Andy made the disclosure in an interview given to the New York Times." Their initial goal is to automate the woefully manual process of electronics manufacturing.
OldJuke writes "Called the YotaPhone, the device pairs a traditional LCD color touch-screen on one side with a black-and-white, electronic-paper display on the other, allowing users to continuously view data in real time without having to constantly wake up their phones and drain their batteries. General interaction will be done through the LCD screen, but the e-paper display allows an image to be displayed at all times — from maps, airline boarding passes and family photos to Twitter messages and emails — but only uses power when the picture changes. BBC News interviewed the company's leader, Vlad Martynov, for a hands-on demonstration."
theodp writes "'The desktop or laptop is now in decline,' writes John Sall, 'squeezed from one side by mobile platforms and from the other side by the cloud. As a developer of desktop software [by choice not necessity], I believe it is time to address the challenges to our viability. Is software for the desktop PC now the living dead, or zombieware.' While conceding there's some truth to truisms about the death of the desktop, Sall believes there's still life in the old desktop dog, 'We live in a world of computing where dreams come true,' Sall concludes. 'The mainframe bows to the minicomputer. The minicomputer bows to the personal computer. The personal computer bows to the tablet and smart phone. It seems as if these will soon bow to the smart watch or smart glasses. But at each step along the way, some applications find their best home – and other applications as well as new applications find the more convenient and smaller home better...So let's keep our desktops and laptops, our PCs and Macs. They are amazingly good at what they do.'"
MojoKid writes "There's a great deal riding on the launch of AMD's next-generation Kaveri APU. The new chip will be the first processor from AMD to incorporate significant architectural changes to the Bulldozer core AMD launched two years ago and the first chip to use a graphics core derived from AMD's GCN (Graphics Core Next) architecture. A strong Kaveri launch could give AMD back some momentum in the enthusiast business. Details are emerging that point to a Kaveri APU that's coming in hot — possibly a little hotter than some of us anticipated. Kaveri's Steamroller CPU core separates some of the core functions that Bulldozer unified and should substantially improve the chip's front-end execution. Unlike Piledriver, which could only decode four instructions per module per cycle (and topped out at eight instructions for a quad-core APU), Steamroller can decode four instructions per core or 16 instructions per quad-core module. The A10-7850K will offer a 512-core GPU while the A10-7700K will be a 384-core part. Again, GPU clock speeds have come down, from 844MHz on the A10-6800K to 720MHz on the new A10-7850K but should be offset by the gains from moving to AMD's GCN architecture."
