Coolant Glitch Forces Partial Space Station Shutdown
Posted by: astroengine
A coolant system glitch on the International Space Station has forced several of the orbital outpost's modules offline as astronauts and ground control manage the problem. The crew are not in danger and ground control teams are currently working to see how best to troubleshoot. The issue, that occurred early on Wednesday, focuses on one of the space station's two external ammonia cooling loops, along which the station's electrical systems use to regulate their temperatures. The loop 'automatically shut down when it reached pre-set temperature limits,' said NASA in a statement. It is thought that a flow control valve in the ammonia pump itself may have malfunctioned.

Program to Use Russian Nukes for US Electricity Comes to an End
Posted by: gbrumfiel
For the past two decades, about 10 percent of all the electricity consumed in the United States has come from Russian nuclear warheads. Under a program called Megatons to Megawatts, Russian highly-enriched uranium was pulled from old bombs and made into fuel for nuclear reactors. NPR News reports that the program concludes today when the last shipment arrives at a U.S. storage facility. In all nearly 500 tons of uranium was recycled, enough for roughly 20,000 warheads.
AirPlay Alternative Mirrors and Streams To TVs and PCs
Posted by: DeviceGuru
AirTame has developed an AirPlay-like protocol and HDMI dongle for 1080p video streaming and screen mirroring from PCs to PCs and TVs, and has substantially exceeded its $160,000 Indiegogo funding goal. AirTame streams from Windows, Mac, and Linux PCs to other PCs via apps at both ends, and to TVs via the HDMI dongle, and also offers a multicast mode for broadcasting to multiple PCs and TVs for use in classrooms or conferences. But at least initially, there won't be support for Android or iOS devices in the mix, due OS restrictions. The company says it plans to release AirTame's software, API, and protocol source code under a dual-license enabling free use with GPL-like restrictions, and paid use for commercial applications requiring proprietary modifications.
Ask Slashdot: Practical Bitrot Detection For Backups?
Posted by: An
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.)

Affordable 3D Metal Printer Developed Based on RepRap
Posted by: hypnosec
Researchers have developed and open-sourced a low-cost 3D metal printer capable of printing metal tools and objects that can be build for under £1,000. 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.
Amazon Uses Robots To Speed Up Human 'Pickers' In Fulfillment Centers
Posted by: cagraham
The WSJ, combing through Amazon's Q3 earnings report, found that the company is currently using 1,400 robots across three of their fulfillment centers. The machines are made by Kiva Systems (a company acquired by Amazon last year), and help to warehouses more efficient by bringing the product shelves to the workers. The workers then select the right item from the shelf, box it, and place it on the conveyor line, while another shelf is brought. The management software that runs the robots can speed or slow down item pacing, reroute valuable orders to more experienced workers, and redistribute workloads to prevent backlogs.
The Real Story of Hacking Together the Commodore C128
Posted by: szczys
Bil Herd was the designer and hardware lead for the Commodore C128. He reminisces about the herculean effort his team took on in order to bring the hardware to market in just five months. At the time the company had the resources to roll their own silicon (that's right, custom chips!) but this also meant that for three of those five months they didn't actually have the integrated circuits the computer was based on.
Factory-In-a-Day Project Aims To Deploy Work-Ready Robots Within 24 Hours
Posted by: Zothecula
Industrial robots have proven useful in reducing production costs in large factories, with major enterprises enlisting their services to execute repetitive tasks. The Factory-in-a-Day project, which kicked off in October, aims to also make robotic technology beneficial to small and medium enterprises (SMEs), by developing adaptable robots that can be integrated with workplace systems within 24 hours.
Microsoft's New Smart Bra Could Stop You From Over Eating
Posted by: walterbyrd
A team of engineers at Microsoft Research have developed a high-tech bra that's intended to monitor women's stress levels and dissuade them from emotional over-eating. The undergarment has sensors that track the user's heart rate, respiration, skin conductance and movement — all of which can indicate the type of stressful emotions that lead to over-eating, according to Microsoft researchers. The data is sent to a smartphone app, which then alerts users about their mood.
Climatologist James Hansen Defends Nuclear Energy
Posted by: First
James Hansen, the former director of the Goddard Institute of Space Sciences, has been a strong defender of using nuclear energy to replace coal and renewable energy. He and three other researchers had written a letter, arguing just this. In this interview with rediff.com, an Indian news site, he was asked to address some concerns surrounding the issue, especially given the strong feelings generated by it. It may not be Hansen's best interview, but it did bring out his passionate side.
In Three Years, Nearly 45% of All the Servers Will Ship To Cloud Providers
Posted by: dcblogs
IDC expects that anywhere from 25% to 30% of all the servers shipped next year will be delivered to cloud services providers. 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.
US Issues 30-Year Eagle-Killing Permits To Wind Industry
Posted by: Hugh
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.
Nobody Builds Reactors For Fun Anymore
Posted by: stox
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.
Intel SSD Roadmap Points To 2TB Drives Arriving In 2014
Posted by: MojoKid
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
German Court Invalidates Microsoft FAT Patent
Posted by: walterbyrd
A Microsoft storage patent that was used to get a sales ban on products from Google-owned Motorola Mobility in Germany has been invalidated by the German Federal Patent Court. Microsoft's FAT (File Allocation Table) patent, which concerns a 'common name space for long and short filenames' was invalidated on Thursday, a spokeswoman for the Federal Patent Court said in an email Friday. She could not give the exact reasons for the court's decision before the written judicial decision is released, which will take a few weeks.
Create Your Own Bullet Time Camera Rig With Raspberry Pi
Posted by: sfcrazy
A team of extremely creative people have created a really inexpensive bullet time set-up using Raspberry Pis — and the whole set-up costs less than a professional DSLR camera. The rig looks more like the LHC at CERN using nearly half a kilometre of network cables, 48 Raspberry Pis fitted with cameras and PiFace Control. The rig worked perfectly — in terms of doing what a bullet time set-up should do. Raspberry Pis achieved the Hollywood's 'frozen time' effect at a much lesser cost.
Tesla Model S Battery Drain Issue Fixed
Posted by: cartechboy
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.

Moore's Law Blowout Sale Is Ending, Says Broadcom CTO
Posted by: itwbennett
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.

Tesla Would Be Proud: Wireless Charging For Electric Cars Gets Closer To Reality
Posted by: curtwoodward
For some reason, we're still plugging in electric-powered devices like a bunch of savages. But technology developed at MIT could soon make that a thing of the past, at least for hybrid cars. A small Boston-area company, WiTricity, is a key part of Toyota's growing experiment with wireless charging tech---something the world's largest car maker says it will start seriously testing in the U.S., Japan and Europe next year. 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.
The Status of the Fukushima Clean-Up
Posted by: doom
Ian Sample at the Guardian UK does a really thorough write-up of what's going on with the Fukushima Clean-up. From the article: 'Though delicate and painstaking, retrieving the fuel rod assemblies from the pools is not the toughest job the workers face. More challenging by far will be digging out the molten cores in the reactors themselves. Some of the fuel burned through its primary containment and is now mixed with cladding, steel and concrete. The mixture will have to be broken up, sealed in steel containers and moved to a nuclear waste storage site. That work will not start until some time after 2020.'
