Watch as one of the DARPA challenge teams makes Atlas walk, unaided, on randomness. This video of Atlas was created by the Florida Institute For Human and Machine Cognition robotics team. It shows Atlas walking across a random collection of obstacles. Notice that even though it looks as if Atlas is supported by a tether, it isn't — as proved when it falls over at the end."

Rambo Tribble writes "In what appears to be a major reversal of policy, Intel's new president, Renee James, has indicated that Intel will be open to manufacturing chips based on rivals' designs. While the language is a bit tentative, this appears to open an opportunity for such as ARM to benefit from Intel's manufacturing expertise and technology." From the article: "James said Intel will evaluate prospective foundry clients on a 'deal by deal basis, not on an architecture by architecture basis.' That applies, James said, 'even in areas where there may be some competition with businesses that we’re in.'" Intel is already manufacturing FPGAs for Altera that include 64-bit ARM cores.
MojoKid writes "Motorola is forging ahead with the concept of modular, customizable smartphones first put forth by designer Dave Hakkens with his Phonebloks concept. The company said recently that it was officially pursuing such an idea with Project Ara, and Motorola is already putting together important partnerships to make it happen. 3D Systems, a maker of 3D printers and other related products, has signed on to create a 'continuous high-speed 3D printing production platform and fulfillment system' for it. In other words, 3D Systems is going to print parts for the project, and what's more, the company has what appears to be an exclusive agreement to make all the enclosures and modules for Project Ara."
Hugh Pickens DOT Com writes "CNN reports that self-professed Apple fanatic Jonathan Zufi has published a book of photography profiling 500 of Apple's products through the years, because unlike other companies Apple has unapologetically focused on design says Zufi and he wants to celebrate that with his images. 'Other companies came up with the guts for a machine and then the engineers would find a way to stuff them into a box,' says Zufi. 'Steve Jobs started with the box and said, "You need to find a way to get the guts in."' It's an unlikely project for a software engineer with no formal photography training. Zufi bought new equipment and consulted with a professional as he began the project, which was four years in the making. 'I had a sudden memory of an old game I used to play in high school called Robot War,' says Zufi. 'I hopped on eBay to look for the game and an old Apple II to play it on, and that's how I ended up looking through old Apple products.' Zufi says that he approached each shot by looking for an image that would 'create that same emotional connection to that product, but maybe doesn't look like something you've seen before,' and says that his mission is to showcase the entire spectrum of products that Apple have sold to the public since 1976 – every desktop, every laptop, every notebook, monitor, iPod, iPad, iPhone, mouse, keyboard, modem, cable, port, adapter, docking station, memory expansion card — and that's just their hardware."
MojoKid writes "When Intel debuted Haswell this year, it launched its first mobile processor with a massive 128MB L4 cache. Dubbed "Crystal Well," this on-package (not on-die) pool of memory wasn't just a graphics frame buffer, but a giant pool of RAM for the entire core to utilize. The performance impact from doing so is significant, though the Haswell processors that utilize the L4 cache don't appear to account for very much of Intel's total CPU volume. Right now, the L4 cache pool is only available on mobile parts, but that could change next year. Apparently Broadwell-K will change that. The 14nm desktop chips aren't due until the tail end of next year but we should see a desktop refresh in the spring with a second-generation Haswell part. Still, it's a sign that Intel intends to integrate the large L4 as standard on a wider range of parts. Using EDRAM instead of SRAM allows Intel's architecture to dedicate just one transistor per cell instead of the 6T configurations commonly used for L1 or L2 cache. That means the memory isn't quite as fast but it saves an enormous amount of die space. At 1.6GHz, L4 latencies are 50-60ns which is significantly higher than the L3 but just half the speed of main memory."

cartechboy writes "The electric car challenge is what insiders call "getting butts in seats" — and a lot of butts today still belong to humans who are not yet buying electric cars. The big question is: Why? Surveys show drivers are interested in electric cars--and that they love them once they drive them. EVs also cost less to maintain (though more to buy in the first place) and many experts say they're simply nicer to drive. So what's the problem? Disinterested dealers, uneven distribution, limited supplies, and media bias are some potential challenges. Or maybe it's just lousy marketing--casting electric cars as a moral imperative or a duty, like medicine you have to take."
necro81 writes "Little known even in environmental circles is a renewable energy success story: five geothermal power plants on Leyte Island in the Philippines — each of which produces enough power for the entire island — that collectively produce more than 10% of the Philippines' total electrical demand. From boreholes deep underground comes pressurized water heated to 280 Celsius. At the surface it flashes into steam, turning one set of turbines, then cools and contracts to spin a second set of turbines. The low-grade steam is then condensed back into water and reinjected into the bedrock. But Typhoon Haiyan destroyed the cooling towers, snapped transmission towers, and scattered the employees."
mdsolar sends this quote from an article about the politics of solar energy: "Clean energy technology has always been an easy punching bag for conservatives. Propelled by growing strain of global warming denial within their party, Republicans in Congress have proposed to slash funding for renewable energy programs in half this year, and mocked the idea of a green economy as “groovy” liberal propaganda. Their argument, as laid out by House Republicans and libertarian organs like the Cato Institute and Reason magazine, is that the federal government shouldn't 'pick winners and losers' in the energy markets or gamble taxpayer dollars on renewable-energy loans to companies like Solyndra, the Silicon Valley solar panel manufacturer that went bankrupt in 2011 after receiving $535 million in federal loan guarantees. The assumption has always been that, without heavy government subsidies, renewable energy sources like solar and wind power would never be able to compete with fossil fuels. But something funny has happened to renewables that major power companies and their Republican allies didn't see coming. Over the past two years, the solar industry has skyrocketed, with one new solar unit installed every four minutes in the US, according to the renewable energy research group Greentech Media. The price of photovoltaic panels has fallen 62 percent since January 2011. Once considered a boutique energy source, solar power has become a cost-competitive alternative for many consumers, costing an average $143 per megawatt-hour, down from $236 in the beginning of 2011. Backed by powerful conservative groups, public utilities in several states are now pushing to curb the solar industry, and asking regulators to raise fees and impose new restrictions on solar customers. And as more people turn to rooftop solar as a way to reduce energy costs—90,000 businesses and homeowners installed panels last year, up 46 percent from 2011—the issue is pitting pro-utilities Republicans against this fledgling movement of libertarian-minded activists who see independent power generation as an individual right. In other words, the fight over solar power is raging within the GOP itself."
alphadogg writes "With memory, as with real estate, location matters. A group of researchers from AMD and the Department of Energy's Los Alamos National Laboratory have found that the altitude at which SRAM resides can influence how many random errors the memory produces. In a field study of two high-performance computers, the researchers found that L2 and L3 caches had more transient errors on the supercomputer located at a higher altitude, compared with the one closer to sea level. They attributed the disparity largely to lower air pressure and higher cosmic ray-induced neutron strikes. Strangely, higher elevation even led to more errors within a rack of servers, the researchers found. Their tests showed that memory modules on the top of a server rack had 20 percent more transient errors than those closer to the bottom of the rack. However, it's not clear what causes this smaller-scale effect."

Wenji presented his work as part of a poster series of new research at the SC 2013 supercomputing conference this week in Denver."
goodminton writes "I'm research the long-term consistency and reproducibility of math results in the cloud and have questions about floating point calculations. For example, say I create a virtual OS instance on a cloud provider (doesn't matter which one) and install Mathematica to run a precise calculation. Mathematica generates the result based on the combination of software version, operating system, hypervisor, firmware and hardware that are running at that time. In the cloud, hardware, firmware and hypervisors are invisible to the users but could still impact the implementation/operation of floating point math. Say I archive the virutal instance and in 5 or 10 years I fire it up on another cloud provider and run the same calculation. What's the likelihood that the results would be the same? What can be done to adjust for this? Currently, I know people who 'archive' hardware just for the purpose of ensuring reproducibility and I'm wondering how this tranlates to the world of cloud and virtualization across multiple hardware types."

50000BTU_barbecue writes "I made a comment a few days ago in a story basically saying the oscilloscope is dead. While that's a bit dramatic, I've found that over the last 20 years my oscilloscopes have been 'on' less and less. Instead, I use a combination of judicious voltage measurements, a logic analyzer and a decent understanding of the documentation of the gadget I'm working on. Stuff is just more and more digital and microcontroller-based, or just so cheap yet incredibly integrated that there's no point in trying to work on it. (I'm thinking RC toys for example. Undocumented and very cheap. Doesn't work? Buy another.) While I still do old-school electronics like circuit-level troubleshooting (on old test gear), that's not where the majority of hobbyists seem to be. Yet one thing I keep hearing is how people want an oscilloscope to work on hardware. I think it's just not that necessary anymore. What I use most are two regulated DC lab supplies, a frequency counter, a USB logic analyzer, a USB I2C/SPI master, and a USB-RS-232 dongle. That covers a lot of modern electronics. I have two oscilloscopes, a 100MHz two-channel stand-alone USB unit and a 1960s analog plug-in-based mainframe that is a '70s hacker dream scope. But I rarely use them anymore. What equipment do hardware folks out there use the most? And would you tell someone trying to get into electronics that they need a scope?"

'Microsoft’s first tweaks for a new controller focused on the overall size and how it’d fit into hands, golden or otherwise. Using the Xbox 360 controller as a starting point, the engineers would make plastic-molded or 3D-printed prototypes that were each 1 millimeter wider or narrower than the last, testing a full range of up to plus or minus 8 millimeters. “That gave us the ability to test, with actual users including women and children, which width feels best,” said Morris. “We tested with more than 500 people throughout the course of the project. All ages, all abilities.” ... Morris and his team then looked at different thicknesses and shapes of the grips (or “lobes,” as he calls them), plus the angle of the triggers, different styles of analog sticks, and more.'"

Ubuntu developers aren't looking to enable discard at the file-system level since it can slow down delete operations, so instead they're wanting to have their own cron job that routinely runs fstrim for TRIMing the system. In the past there has been talk about the TRIM implementation being unoptimized in the kernel. Around when Linux 3.0 was released, OpenSUSE noted that the kernel performs TRIM to a single range, instead of vectorized list of TRIM ranges, which is what the specification calls for. In some scenarios this results in lowered performance."

Nerval's Lobster writes "A small handful of Tesla electric cars have caught fire, driving down the company's stock price, and finally prompting CEO Elon Musk to tackle the issue in a new blog posting. 'Since the Model S went into production last year, there have been more than a quarter million gasoline car fires in the United States alone, resulting in over 400 deaths and approximately 1,200 serious injuries (extrapolating 2012 NFPA data),' he wrote in that posting. 'However, the three Model S fires, which only occurred after very high-speed collisions and caused no serious injuries or deaths, received more national headlines than all 250,000+ gasoline fires combined.' Responsible journalism on the matter, he added, has been 'drowned out' by 'an onslaught of popular and financial media seeking to make a sensation out of something that a simple Google search would reveal to be false.' According to his own figures, Tesla suffers an average of one fire per 6,333 cars, versus a rate of one fire per 1,350 gasoline-powered cars. Every Tesla vehicle includes internal walls between the battery modules, in addition to a firewall between the battery pack and the passenger compartment — enough shielding, in the event of a fire, to prevent pens and papers in the glove compartment from combusting. 'Despite multiple high-speed accidents, there have been no deaths or serious injuries in a Model S of any kind ever,' Musk continued. 'Of course, at some point, the law of large numbers dictates that this, too, will change, but the record is long enough already for us to be extremely proud of this achievement.' Tesla is about to push an 'over-the-air update' to its vehicles' air suspension that will create more ground clearance at highway speeds. In theory, that could reduce the chances of impact damage to the underbody, should the vehicle roll over an object — and that, in turn, could lower the chances of fire."

MojoKid writes "The supercomputing conference SC13 kicks off this week and Nvidia is kicking off their own event with the launch of a new GPU and a strategic partnership with IBM. Just as the GTX 780 Ti was the full consumer implementation of the GK110 GPU, the new K40 Tesla card is the supercomputing / HPC variant of the same core architecture. The K40 picks up additional clock headroom and implements the same variable clock speed threshold that has characterized Nvidia's consumer cards for the past year, for a significant overall boost in performance. The other major shift between Nvidia's previous gen K20X and the new K40 is the amount of on-board RAM. K40 packs a full 12GB and clocks it modestly higher to boot. That's important because datasets are typically limited to on-board GPU memory (at least, if you want to work with any kind of speed). Finally, IBM and Nvidia announced a partnership to combine Tesla GPUs and Power CPUs for OpenPOWER solutions. The goal is to push the new Tesla cards as workload accelerators for specific datacenter tasks. According to Nvidia's release, Tesla GPUs will ship alongside Power8 CPUs, which are currently scheduled for a mid-2014 release date. IBM's venerable architecture is expected to target a 4GHz clock speed and offer up to 12 cores with 96MB of shared L3 cache. A 12-core implementation would be capable of handling up to 96 simultaneous threads. The two should make for a potent combination."

Several sources, including this report at Forbes, and this one at All Things Digital, say that Apple has bought (or is in the process of buying) Tel-Aviv based PrimeSense, the company behind the 3-D sensing technology in Microsoft's Kinect, for $345 million. The Forbes piece also gives a compact but interesting summary of the possibilities of ubiquitous 3-D hardware, and the sudden, recent drop in price of the components necessary for that to happen. Devices like the Lynx 3-D scanner that I saw at last year's SXSW (targeting the cheap and portable end of the 3-D scanning market) may have a lot of competition in the near future.
The Raspberry Pi project that we've been fans of for quite a while now has hit a new milestone: Today, they announced that as of the last week in October, the project has sold more than two million boards. Raspberry Pi is anything but alone in the tiny, hackable computer world (all kinds of other options, from Arduino to the x86-based Minnowboard, are out there, and all have their selling points), but the low price, open-source emphasis, and focus on education have all helped the Pi catch on.

New submitter isza writes "MobilECG is probably the first open source clinical-grade electrocardiograph with simultaneous 12-lead recording and Android support. It has been designed to meet all the relevant medical standards (ISO 60601-1, etc.). Manufacturing cost @ 1000 pieces: ~$110. I had worked at a medical device company designing clinical electrocardiographs for three years. Fed up with the unreasonably high price, cumbersome design, and dishonest distribution practices of clinical ECG machines, I started working on a high-quality ECG that is different. After a couple of failed attempts to get funding for the expensive certification process and completely running out of funds, I decided to publish everything under a license that allows others to finalize and manufacture it or reuse parts of it in other projects." From the project page linked: "The software is licensed under WTFPL, the hardware under CERN OHL 1.2," and a few words of disclaimer: "Note: the design is functional but unfinished, it needs additional work before it can be certified. There are also some known bugs in it. Most of the software is unimplemented." Conventional crowdfunding may have fallen short, but Isza has proposed an interesting bargain for working on the project again himself: that will happen if he raises via donation half the amount of his original $22,000 investment.

The announcement cast a shadow over international talks underway in Warsaw aimed at fashioning a new global pact to address the threats of a changing climate. Under its new goal, Japan, one of the world's top polluters, would still seek to reduce its current emissions. But it would release 3 percent more greenhouse gases in 2020 than it did in 1990, rather than the 6 percent cut it originally promised or the 25 percent reduction it promised two years before the 2011 nuclear disaster."

The Arizona Corporation Commission, which regulates utilities in the state, agreed in a 3-to-2 vote at a meeting [Thursday] in Phoenix that Arizona Public Service Co. may collect about $4.90 a month from customers with solar systems. Arizona Public is required to buy solar power from customers with rooftop panels, and the commission agreed with its argument that the policy unfairly shifts some of the utility's costs to people without panels. Imposing a fee designed to address this issue may prompt power companies in other states to follow suit, and will discourage some people from installing new systems, according to the Sierra Club."

OBI is an example of passive two-phase cooling, which uses a boiling liquid to remove heat from a surface and then condenses the liquid for reuse, all without a pump. It's a slightly different approach to immersion cooling than the Green Revolution technique being tested by Intel and deployed at scale by energy companies. Other players in immersion cooling include Iceotope and Hardcore (now LiquidCool)."

Users were complaining about the issues with the trackpad and performance of the laptop." Specifically (as also reported by the Seattle Post-Intelligencer), some of the laptops have been reported to overheat.
MojoKid writes "The seemingly never-ending onslaught of new graphics cards as of late continues today with the official release of the AMD Radeon R9 270. This mainstream graphics card actually leverages the same GPU that powered last-year's Radeon HD 7870 GHz Edition. AMD, however, has tweaked the clocks and through software and board level revisions updated the card to allow for more flexible use of its display outputs (using Eyefinity no longer requires the use of a DisplayPort). Versus the 1GHz (GPU) and 4.8Gbps (memory) of the Radeon HD 7870 GHz Edition, the Radeon R9 270 offers slightly lower compute performance (2.37 TFLOPS vs. 2.56 TFLOPS), but much more memory bandwidth--179.2GB/s vs. 153.6GB/s to be exact. AMD and its add in board partners are launching the Radeon R9 270 today, with prices starting at $179. The Radeon R9 270's starting price is somewhat aggressive and once again puts pressure on NVIDIA. GeForce GTX 660 cards, which typically performed lower than the Radeon R9 270 are priced right around the $190 mark. Along with this card, AMD is also announcing an update to its game bundle, and beginning November 13 Radeon R9 270 – R9 290X cards will include a free copy of Battlefield 4. NVIDIA, on the other hand, is offering Splinter Cell: Blacklist and Assassins Creed – Black Flag, plus $50 off a SHIELD portable gaming device with GTX 660 and 760 cards."
rtoz writes "MIT researchers have found that adding genetically modified viruses to the production of nanowires will boost the performance of lithium-air battery used in electric cars. The key to their work was to increase the surface area of the wire, thus increasing the area where electrochemical activity takes place during charging or discharging of the battery (abstract). The increase in surface area produced by their method can provide a big advantage in lithium-air batteries' rate of charging and discharging. Unlike conventional fabrication methods, which involve energy-intensive high temperatures and hazardous chemicals, this process can be carried out at room temperature using a water-based process."
Daniel_Stuckey writes "At the start of this year, President Obama nicely summed up the grandiose promise of 3D printing — or rather, the hype surrounding it. In his State of the Union address the president suggested the fledgling technology could save manufacturing by ushering in a second industrial revolution. That shout-out inspired a spate of buzzkill blog posts pointing out — rightly enough — that despite its potential, 3D printing is still in its infancy. It's not the panacea for the struggling economy we want it to be, at least not yet. Apparently the naysayers weren't enough to kill the 3D-printing dream, because, with support from the federal government, MakerBot announced its initiative to put a 3D printer in every school in America. The tech startup and the administration are betting big that teaching kids 3D printing is teaching them the skills they'll need as tomorrow's engineers, designers, and inventors." Caveat: Makerbot no longer produces open hardware, and they are pushing proprietary Autodesk software and educational materials as part of the free 3D printer. Makerbot also launched a call for open models of math manipulatives on Thingiverse (you might remember them from elementary school) so that teachers have something useful to print immediately.
muterobert writes with an article about a new head mounted virtual retinal display (technology last covered ages ago). The folks over at Road to VR took a look at an engineering prototype; from the article: "The Avegant HMD uses a virtual retinal projection display consisting of a single LED light source and an array of micro-mirrors. This differs from normal screens in that with a VRD there is no actual screen to look at. Instead, a virtual image (in the optical sense) is drawn directly onto your retina. . ... 'At one point I was looking at a sea turtle in shallow coral waters. Sunlight was beaming down from the surface and illuminating the turtle's shell in a spectacular way — it was one of the most vivid and natural things I've ever seen on any display. The scene before me looked incredibly real, even though the field of view is not at immersive levels.'"
MojoKid writes "At APU13 today, AMD announced a full suite of new products and development tools as part of its push to improve HSA development. One of the most significant announcements to come out the sessions today-- albeit in a tacit, indirect fashion, is that Kaveri is going to pack a full 512 GPU cores. There's not much new to see on the CPU side of things — like Richland/Trinity, Steamroller is a pair of CPU modules with two cores per module. AMD also isn't talking about clock speeds yet, but the estimated 862 GFLOPS that the company is claiming for Kaveri points to GPU clock speeds between 700 — 800MHz. With 512 cores, Kaveri picks up a 33% boost over its predecessors, but memory bandwidth will be essential for the GPU to reach peak performance. For performance, AMD showed Kaveri up against the Intel 4770K running a low-end GeForce GT 630. In the intro scene to BF4's single-player campaign (1920x1080, Medium Details), the AMD Kaveri system (with no discrete GPU) consistently pushed frame rates in the 28-40 FPS range. The Intel system, in contrast, couldn't manage 15 FPS. Performance on that system was solidly in the 12-14 FPS range — meaning AMD is pulling 2x the frame rate, if not more."
