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."

I'm sure this is a common problem for those who own higher-end calculators. 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."
ClaraBow writes "I find it interesting that Dell has started selling a thin and light touchscreen laptop called the XPS 13 Developer Edition, which will have Ubuntu Linux OS and Intel's fourth-generation Core processors, code-named Haswell.

It is priced starting at $1,250 and is available in the U.S." One thing I wish was addressed in the blog post announcing this newest entry in the Sputnik line, or its listed specs (bad news beats not knowing, in this case), is battery life.
Lucas123 writes "Google just announced it is investing another $80 million in six new solar power plants in California and Arizona, bringing its total investment in renewable energy to more than $1 billion. The new plants are expected to generate 160MW of electricity, enough to power 17,000 typical U.S. homes. They are expected to be operational by early 2014. 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."
waderoush writes "Anki gained instant fame as the robot-car company that launched at Apple's WWDC in June. 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.'"

dcblogs writes "One year ago this month, the U.S. Department of Energy announced a $120 million plan to develop a technology capable of radically extending battery life. 'We want to change the game, basically,' said George Crabtree, a senior scientist at Argonne National Laboratory and a physics professor who is leading the effort. 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."
Rambo Tribble writes "The BBC reports on efforts at Sydney University, where researchers have had excellent success herding dairy cows with robots. By designing the robots to move smoothly, they have kept the cows moving without stressing them. From the video, one can see the animals seem not to interpret the machine as any threat. '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. 'Robots allow [soldiers] to be more lethal and engaged in their surroundings,' said Lt. Col. Willie Smith, chief of Unmanned Ground Vehicles at Fort Benning, Ga. 'I think there's more work to be done but I'm expecting we'll get there.'"
First time accepted submitter NoImNotNineVolt writes "Coin, a Y Combinator-backed startup, has started accepting pre-orders for a device as slim as a standard piece of payment plastic that can hold eight credit, debit, and gift cards in its dynamic magnetic stripe. Paired with the Coin smartphone app via Bluetooth low energy, card details can easily be swapped in and out of the device. A minimalist user interface on the device itself allows the owner to toggle between the loaded cards and then swipe just as they would their ordinary card. All card details are encrypted (both on the device and in the smartphone app), and the device's on-board battery is expected to last for two years of typical usage. No support for chip&pin (EMV) yet, so this may have limited utility outside of the USA. They expect to start shipping in summer of 2014."

mahiskali writes with this interesting news via the EFF's Deep Links "The new Renault Zoe comes with a 'feature' that absolutely nobody wants. 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."
miller60 writes "How do you cool a high-density server installation inside a high rise in Hong Kong? 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."

MarkWhittington writes "Project M was a proposal at NASA's Johnson Spaceflight Center that would have put together a mission to deliver a bipedal robot to the lunar surface within a thousand days. The idea never got out of the conception stage, but two major components, a new type of lunar lander, now called Morpheus, and a robonaut continued on as separate projects. 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?"

Hugh Pickens DOT Com writes "Matthew Philips writes at Bloomberg that US Secretary of State John Kerry landed in Geneva on Friday to begin negotiations with Iran over its nuclear weapons program and there is sudden optimism that a deal is in the offing. But the simple fact is that Iran would not be coming to the negotiating table without the US oil boom. 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.

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.)"

MojoKid writes "One of the hallmark features of Google's Nexus 5 flagship smartphone by LG isn't its bodaciously big 5-inch HD display, its 8MP camera, or its "OK Google" voice commands. That has all been done before. What does stand out about the Nexus 5 is Google's new Android 4.4 Kit Kat OS and LG's SoC (System on Chip) processor of choice, namely Qualcomm's Snapdragon 800 quad-core. Qualcomm is known for licensing ARM core technology and making it their own; and Qualcomm's latest Krait 400 quad-core along with the Adreno 330 GPU that comprise the Snapdragon 800, is a powerful beast. Google also has taken the scalpel to Kit Kat in all the right places, whittling down the overall footprint of the OS, so it's more efficient on lower-end devices and also offers faster multitasking. Specifically memory usage has been optimized in a number of areas. Couple these OS tweaks with Qualcomm's Snapdragon 800 and you end up with a smartphone that hugs the corners and lights 'em up on the straights. Putting the Nexus 5 through its paces, it turns out preliminary figures are promising. In fact, the Nexus 5 actually was able to surpass the iPhone 5s with Apple's 64-bit A7 processor in a few tests and goes toe to toe with it in gaming and graphics." Ars Technica has a similarly positive view of the hardware aspects of the phone, dinging it slightly for its camera but otherwise finding little to fault.

Security experts have repeatedly said that it you want to trust this type of software, your best bet is to choose software that is open source. But, in order to be entirely sure, a security audit of the code by independent experts sounds like a definitive answer to that issue. And that it exactly what Matthew Green, cryptographer and research professor at Johns Hopkins University, and Kenneth White, co-founder of hosted healthcare services provider BAO Systems, have set out to do. The software that will be audited is the famous file and disk encryption software package TrueCrypt.

Nerval's Lobster writes "By 2015, Americans' ability to access digital media at home and on mobile devices will raise the average volume of media consumed to the equivalent of nine DVDs worth of data per person, per day – not including whatever media they consume at work. That estimate adds up to 15.5 hours of media use per day per person, which breaks down to 74 gigabytes of data per person and a national, collective total of 8.75 zettabytes, according to a new report. Between 2008 and 2013, Americans grew from watching 11 hours of media per day to 14 hours per day – a growth rate of about 5 percent per year, lead author James E. Short wrote in the report. The increasing number of digital-data consumers and the shift from analog to digital media drove the total volume of data in bytes to grow 18 percent per year. That growth rate 'is less than the capacity to process data, driven by Moore's Law, [of about] 30 percent per year,' he added, 'but is still impressive.' Social media is growing even faster than other options – 28 percent per year, from 6.3 billion hours in 2008 to an estimated 35.2 billion hours in 2015. Companies expecting to catch the attention of either employees or customers will have to do so in the context of an increasingly media-swamped population. Digital data consumption will continue to rise, the SDSC projections estimate, possibly to more than an average of 24 hours per person per day – which is only possible assuming multiple simultaneous data streams running through the minds of Americans watching TV, browsing the Web and texting each other simultaneously, probably to ask why they never have time to just sit and talk any more."

That move caused AMD to rejigger its plans for the new Radeon R9 290, which debuted today with a higher default fan speed and faster performance than originally planned. This $400 card offers almost identical performance to AMD's flagship R9 290X for $150 less. Indeed, it's often faster than Nvidia's $1000 GeForce Titan. But the 290 also consumes a lot more power, and its fan spins up to 49 decibels under load. Fortunately, the acoustic profile isn't too grating. Radeon R9 290 isn't the only new graphics card due this week, either. Nvidia is scheduled to unveil its GeForce GTX 780 Ti on November 7, and that card could further upset the balance at the high end of the GPU market. As AMD and Nvidia trade blows, PC gamers seem to be the ones who benefit." Additional reviews available from AnandTech, PC Perspective, Hot Hardware, and Tom's Hardware.
First time accepted submitter 192_kbps writes "Mike Clements, a long-haul trucker from West Jordan, Utah, built the largest amateur telescope ever with a whopping 70 inch primary mirror he purchased at auction. The entire telescope is 35 feet tall, 900 pounds, and he hopes to tour it in parks. As a hand-turned Dobsonian the telescope lacks the photographic capacity and tracking required for professional astronomy but the views must be breathtaking." (Are there other compelling candidates out there for "largest amateur telescope ever"? The 71" scope listed by nitesky.org appears to be dormant.)
alphadogg writes "The equipment is big and expensive, with the research costs at almost $500,000. But by just using retail components, Chinese professor Chi Nan has built her own Li-Fi wireless system that can use LED lights to send and receive Internet data. "I bought the lights from Taobao," she said, referring to the Chinese e-commerce site. The professor from Fudan University showed off the technology on Tuesday at the China International Industry Fair in Shanghai. Unlike traditional Wi-Fi routers that use radio signals, Chi's system relies on light to send and receive data wirelessly. Others scientists, especially in the U.K., have also been researching the technology, and dubbed it "Li-Fi". But rather than develop specialized hardware, Chi bought off-the-shelf retail parts to create her system."
First time accepted submitter neapolitan writes "PBS has a report on the difficulties of tracking the complications arising from surgical robotic systems, particularly the Da Vinci robotic surgery apparatus. The original study (paywall) notes that there is a large lag in filing reports, and some are not reported at all. It is difficult to assess the continued outcomes and safety without accurate reporting data."
slew writes "Although the robot technically cheats because it watches your hand and can recognize what shape you are intending to make and beat it before you even know what is happening. Apparently it takes about 60ms for you to shape your hand, but the robot can recognize the shape before it is completed, and only takes 20ms to counter your shape so the results appear to the human opponent to be virtually simultaneous. I wonder how difficult it would be to add lizard and spock to the mix.... ;^)."
angry tapir writes "A group of Microsoft researchers believe that using fuel cells to power data centers could potentially result in an 'over 20% reduction in costs using conservative projections', cutting infrastructure and power input costs. In addition, using fuel cells would likely result in a smaller carbon footprint for data centers. The researchers looked at the potential of using fuel cells at the rack level to power servers in data centers — although they note there is a long way to go before this could become a reality (not least of the small worldwide production level of fuel cells)."
