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."

Lucas123 writes "Epson and Evena Medical today unveiled a new smart-glass technology that allows nurses to see 'through' a patient's skin to the vasculature beneath in order to make intravenous placement easier. The Eyes-On Glasses System is based on Epson's Moverio Smart Glasses Technology, an Android-based, see-through wearable display launched earlier this year that allows users to interact with apps and games. The glasses use near-infrared light to highlight deoxygenated hemoglobin in a patient's veins and capture the images with two stereoscopic cameras. The cameras then project the vein images onto the see-through glass screens. The glasses can store the images and video and transfer them wirelessly to a patient's electronic health record, and they also come with dual built-in speakers for video conferencing."
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?"
jfruh writes "We've reached a point in our electronic lives where most of our gadgets draw power from a USB cable, and we have lots of USB ports to choose from — some of which live on other gadgets, some of which live on adapters that plug into your wall or car.

The Practical Meter, the product of a successful Kickstarter campaign, can help you figure out which power sources are going to juice up your gadgets the fastest."
mrspoonsi writes "The Xbox One controller went through many radical designs, including a built-in pico projector and a cartridge designed to release smell. Apparently, 'the core base didn't appreciate them,' so these wacky features were dropped in favor of a standard controller. According to VentureBeat, over $100 million worth of research went into the design they ended up using. '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.'"
jones_supa writes "During the first day of the latest virtual Ubuntu Developer Summit, Canonical developers finally plotted out the enabling of TRIM/DISCARD support by default for solid-state drives on Ubuntu 14.04. 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."

The device is called "Project Discovery" and will come with AMD's Mullins chip that is a 64-bit, x86-based chip, perfectly suitable for Windows 8.1. The low-power Mullins APU (accelerated processing unit) is AMD's answer to Intel, Nvidia and Qualcomm, aimed at fanless tablets, ultrathin notebooks, and 2-in-1 devices. The 28nm processor is expected to consume as little as 2 watts of energy while in use. The obtained images show that the upcoming AMD tablet is quite similar to Razer Edge."
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."
With her signature pink hair, MIT engineer Limor Fried has become a force in the maker movement.

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. If yours is one of these 2 million, what are you using it for? (And if you favor some other small system for your own experiments, what factors matter?)
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.
mdsolar writes with this excerpt from the New York Times: "Japan took a major step back on Friday from earlier pledges to slash its greenhouse gas emissions, saying a shutdown of its nuclear power plants in the wake of the Fukushima disaster had made previous targets unattainable. 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."

Sure, I could just buy a random $15 calculator with a few trig functions, but I was wondering who makes the best moderately-priced calculators for somebody who already has and appreciates a programmable calculator and just needs something simple. Bonus points if the calculator can handle polar vector arithmetic and unit conversions, but it has to be simple enough that virtually any exam would accept its use."

With the new plants, Google's renewable power facilities will be able to generate a total of 2 billion watts (gigawatts) of energy, enough to power 500,000 homes or all of the public elementary schools in New York, Oregon, and Wyoming for one year, it said. Currently, Google gets about 20% of its power from renewable energy, but it has set a goal of achieving 100% renewable energy."
mdsolar writes with this excerpt from Bloomberg News: "Arizona will permit the state's largest utility to charge a monthly fee to customers who install photovoltaic panels on their roofs, in a closely watched hearing that drew about 1,000 protesters and may threaten the surging residential solar market. 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."

Its iPhone-controlled racing game hit Apple stores in October, and the company is hoping it will be a holiday hit. But while Anki Drive offers offers a novel physical/virtual entertainment experience for kids and their gadget-loving parents, being a toy company 'is not our vision,' says co-founder and CEO Boris Sofman in this combined company profile and product review from Xconomy. Anki Drive is planned as the first in a series of new consumer-robotics products that are intensively AI-driven, as compared to the mechanically sophisticated but relatively instinctual or behavioral robots exemplified by iRobot's Roomba (which is probably the most successful consumer robot to date). The common characteristics of Anki's coming products, in Sofman's mind: 'Relatively simple and elegant hardware; incredibly complicated software; and Web and wireless connectivity to be able to continually expand the experience over time.'"

The goal is to develop a battery that can deliver five times the performance, measured in energy density, that's also five times cheaper, and do it in five years. They are looking at three research areas. Researchers are considering replacing the lithium with magnesium that has two charges, or aluminum, which has three charges. Another approach investigates replacing the intercalation step with a true chemical reaction. A third approach is the use of liquids to replace crystalline anodes and cathodes, which opens up more space for working ions."

'The robot could also cut down the number of accidents involving humans on farms. Most dairy farmers in Australia use quad bikes to round up their cattle and they are one of the leading causes of injury. The team hopes that by using the robot to do the job instead, accident rates could fall.'"

Benning in Georgia last month. The companies are already gaining traction in the military. For example, British military forces, use QinetiQ's 10-pound Dragon Runner robot, which can be carried in a backpack and then tossed into a building or a cave to capture and relay surveillance video.

Instead of selling consumers a complete car that they can use, repair, and upgrade as they see fit, Renault has opted to lock purchasers into a rental contract with a battery manufacturer and enforce that contract with digital rights management (DRM) restrictions that can remotely prevent the battery from charging at all. This coming on the heels of the recent Trans-Pacific Partnership IP Rights Chapter leak certainly makes you wonder how much of that device (car?) you really own. Perhaps Merriam-Webster can simply change the definition of ownership."

You dunk the servers, immersing them in fluid to create an extremely efficient HPC environment in a hot, humid location. Hong Kong's Allied Control developed its immersion cooling solution using a technique called open bath immersion (OBI), which uses 3M's Novec fluid. 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)."

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."
MrSeb writes with this excerpt, linking to several pretty graphs: "For more than 30 years, the realm of computing has been intrinsically linked to the humble hard drive. It has been a complex and sometimes torturous relationship, but there's no denying the huge role that hard drives have played in the growth and popularization of PCs, and more recently in the rapid expansion of online and cloud storage. Given our exceedingly heavy reliance on hard drives, it's very, very weird that one piece of vital information still eludes us: How long does a hard drive last? According to some new data, gathered from 25,000 hard drives that have been spinning for four years, it turns out that hard drives actually have a surprisingly low failure rate."

Morpheus is getting ready to conduct a second attempt at free flight tests at the Kennedy Space Center. The first attempt resulted in the destruction of the prototype vehicle. If the second round of tests is successful, NASA will have a spacecraft that could deliver 1,100 pounds of payload to the lunar surface. While a copy of Robonaut 2 is still undergoing tests on board the International Space Station, ABC News reports that a cousin of the mechanical person has been built with legs. It stands eight feet tall and weighs 500 pounds. With two major components of Project M nearing completion, could a robonaut become the next moon walker?"

Over the last two years, the US has increased its crude production by about 2 million barrels a day. According to a recent report from the Congressional Research Service (pdf), Iran's oil exports have been cut in half since 2011 (PDF), from 2.5 million barrels per day to a bit more than 1 million today. As a result, Iran has had to halt an equal amount of production. 'I think it's pretty clear that without the U.S. shale revolution, it never would have been possible to put this kind of embargo on Iran,' says Julius Walker. 'Without US production gains, I think we'd be looking at $150 a barrel.' Instead, international prices have hovered around $110, and are less than $100 in the US. According to data from Bloomberg, the combined carrying capacity of oil tankers leaving Iranian ports last month dropped 22 percent from September. 'They're having a very hard time finding buyers,' says Walker. If a deal gets done, the trick will be to ease Iranian oil back onto the broader market without disrupting prices. If not managed properly, flooding the market with Iranian crude could carry its own negative consequences by suddenly making fracked oil in the US unprofitable."
mdsolar writes in with news that plans to build two new reactors at the Comanche Peak nuclear power plant have been put on hold. "On Friday, Luminant, a subsidiary of Dallas-based Energy Future Holdings, suspended its application to the U.S. Nuclear Regulatory Commission to build two new reactors at the plant. Its partner on the project, Mitsubishi Heavy Industries, said it was focusing on getting its nuclear reactors in Japan back in operation. The majority of Japan's reactors were shut down because of safety concerns following a 2011 tsunami that caused a radiation leak at the Fukushima Daiichi nuclear complex 150 miles north of Tokyo. Mitsubishi 'has informed us that they will materially slow the development of their design control document for their new reactor design by several years. In addition, both [Mitsubishi] and Luminant understand the current economic reality of low Texas power prices driven in large part by the boom in natural gas,' read a statement from Luminant."
Lucas123 writes "Researchers have already built robots that can use microorganisms to digest waste material, such as rotten fruit and vegetables, and generate electricity from it. This time, a group of scientists has taken that concept to a strange, new place: urine-powered robots. The scientists from the University of the West of England, Bristol and the University of Bristol constructed a system in robots that functions like the human heart, except it's designed to pump urine into the robot's 'engine room,' converting the waste into electricity and enabling the robot to function completely on its own. The researchers hope the system, which can hold 24.5 ml of urine, could be used to power future generations of robots, or what they're calling EcoBots. 'In the city environment, they could re-charge using urine from urinals in public lavatories,' said Peter Walters, a researcher with the University of the West of England. 'In rural environments, liquid waste effluent could be collected from farms.'"
cagraham writes "International engineering and construction firm Balfour Beatty is considering using drones in order to construct walls and monitor work sites, among other things. Beatty CIO Danny Reeves, speaking at the Fujitsu Forum, said drones could improve efficiency and safety on sites. He also talked of implementing sensors that would monitor worker's stress levels and bodily functions, and notify management when they became less effective, or mistake-prone, on the job."
Nerval's Lobster writes "Researchers have demonstrated a technique that produces inexpensive, functional electrical circuits that can be printed using about $300 worth of materials and equipment, including generic inkjet printers. The technique, developed by researchers from Georgia Tech, the University of Tokyo and Microsoft Research, allows circuits to be printed onto irregularly-shaped materials or almost anything able to go through the paper feed on a printer designed for consumers. The chief advantage of the technique is the ability to print circuits using silver nanoparticle ink rather than relying on the thermal-bonding technique called sintering, which is time-consuming and can destroy delicate base materials. Researchers were able to print new circuits in about 60 seconds on almost any material that could go through the printer, though resin-covered paper, PET film and glossy photo paper worked best, while sheets of canvas cloth and anything magnetic were ineffective. Once printed using silver ink on flexible base material, the circuits can be attached to existing hardware by simply laying or taping them in place and making connections using conductive tape or conductive glue. (Soldering would destroy the underlying material.)"
mdsolar writes with this bit of news from Green Tech Media "The German government has responded to the next big challenge in its energy transition – storing the output from the solar boom it has created — by doing exactly what it has successfully done to date: greasing the wheels of finance to bring down the cost of new technology. ... Now it is looking at bringing down the cost of the next piece in the puzzle of its energy transition — battery storage. ... KfW’s aim, according to Axel Nawrath, a member of the KfW Bankengruppe executive board, is to ensure that the output of wind and solar must be 'more decoupled' from the grid. ... This is seen as critical as the level of renewable penetration rises to around 40 per cent — a level expected in Germany within the next 10 years. ... According to Papenfuss, households participating in the scheme will spend between €20,000 and €28,000 on solar and storage, depending on the size of the system (the average size is expected to be around 7kW for the solar array and around 4kWh for the battery)."
