An anonymous reader writes: Bloomberg reports that Samsung has filed a complaint with the U.S. International Trade Commission asking them to block the import of Nvidia's graphics chips . This is part of Samsung's retaliation for a similar claim filed by Nvidia against Samsung and Qualcomm back in September. Both companies are wielding patents pertaining to the improved operation of graphics chips in cell phones and other mobile devices.

jones_supa writes: Eizo has introduced an interesting new PC monitor with a square aspect ratio: the Eizo FlexScan EV2730Q is a 26.5-inch screen with 1:1 aspect ratio and an IPS panel with resolution of 1920 x 1920 pixels. "The extended vertical space is convenient for displaying large amounts of information in long windows, reducing the need for excess scrolling and providing a more efficient view of data," the firm writes. The monitor also offers flicker-free (non-PWM) backlight and reduced blue light features to avoid scorching users' eyes. Would a square display be of any benefit to you?

New submitter lars_stefan_axelsson writes: When I was an undergrad in the eighties, "building" a computer meant that you got a bunch of chips and a soldering iron and went to work. The art is still alive today, but instead of a running BASIC interpreter as the ultimate proof of success, today the crowning achievement is getting Linux to run: "What does it take to build a little 68000-based protoboard computer, and get it running Linux? In my case, about three weeks of spare time, plenty of coffee, and a strong dose of stubbornness. After banging my head against the wall with problems ranging from the inductance of pushbutton switches to memory leaks in the C standard library, it finally works! (video)"

jfruh writes:Computing devices have been gobbling up more and more memory, but storage tech has been hitting its limits, creating a bottleneck. Now researchers in Spain and Scotland have reported a breakthrough in working with metal-oxide clusters that can retain their charge. These molecules could serve as the basis for RAM and flash memory that will be leagues smaller than existing components (abstract).

An anonymous reader writes: When looking for a new (or used) car, I have readily available information regarding features, maintenance history, and potential issues for that specific model or generation. What I would really like is a car that is readily hackable on the convenience-feature level. For example, if I want to install a remote starter, or hack the power windows so holding 'up' automatically rolls it up, or install a readout on the rear of the car showing engine RPMs, what make/model/year is the best pick? Have any of you done something similar with your vehicle? Have you found certain models to be ideal or terrible for feature hacking?

An anonymous reader writes: Microsoft is testing a group of five robot security guards. They contain a sophisticated sensor suite that includes 360-degree HD video, thermal imaging, night vision, LIDAR, and audio recorders. They can also detect various chemicals and radiation signatures, and do some rudimentary behavioral analysis on people they see. (And they look a bit like Daleks.) The robots are unarmed, so we don't have to worry about a revolt just yet, but they can sound an alarm and call for human officers. They weigh about 300 lbs each, can last roughly a day on a battery charge, and know to head to the charging station when they're low on power.

angry tapir (1463043) writes Intel is shrinking PCs to thumb-sized "compute sticks" that will be out next year. The stick will plug into the back of a smart TV or monitor "and bring intelligence to that," said Kirk Skaugen, senior vice president and general manager of the PC Client Group at Intel, during the Intel investor conference in Santa Clara, California. They might be a bit late to the party, but since Skaugen mentioned both Chromecast and Amazon's Fire TV Stick, hopefully that means Intel has some more interesting and general-purpose plans.

Yesterday we ran video #1 of 2 about the Critical Materials Institute (CMI) at the Iowa State Ames Laboratory in Ames, Iowa. They have partners from other national laboratories, universities, and industry, too. Obviously there is more than enough information on this subject that Dr. King can easily fill two 15-minute videos, not to mention so many Google links that instead of trying to list all of them, we're giving you one link to Google using the search term "rare earths." Yes, we know Rare Earth would be a great name for a rock band. But the mineral rare earths are important in the manufacture of items ranging from strong magnets to touch screens and rechargeable batteries, so please watch the video(s) or at least read the transcript(s).

the_newsbeagle writes In 2007, Google boldly declared a new initiative to invent a green energy technology that produced cheaper electricity than coal-fired power plants. Sure, energy researchers had been hammering at this task for decades, but Google hoped to figure it out in a few years. They didn't. Instead, Google admitted defeat and shut down the project in 2011. In a admirable twist, however, two of the project's engineers then dedicated themselves to learning from the project's failure. What did it mean that one of the world's most ambitious and capable innovation companies couldn't invent a cheap renewable energy tech?

StartsWithABang writes After successfully landing on a comet with all 10 instruments intact, but failing to deploy its thrusters and harpoons to anchor onto the surface, Philae bounced, coming to rest in an area with woefully insufficient sunlight to keep it alive. After exhausting its primary battery, it went into hibernation, most likely never to wake again. We'll always be left to wonder what might have been if it had functioned optimally, and given us years of data rather than just 60 hours worth. The thing is, it wouldn't have needed to function optimally to give us years of data, if only it were better designed in one particular aspect: powered by Plutonium-238 instead of by solar panels.

CMI in this context is the Critical Materials Institute at the Iowa State Ames Laboratory in Ames, Iowa. They have partners from other national laboratories, universities, and industry, too. Rare earths, while not necessarily as rare as the word "rare" implies, are hard to mine, separate, and use. They are often found in parts per million quantities, so it takes supercomputers to suss out which deposits are worth going after. This is what Dr. King and his coworkers spend their time doing; finding concentrations of rare earths that can be mined and refined profitably.
On November 3 we asked you for questions to put to Dr. King. Timothy incorporated some of those questions into the conversation in this video -- and tomorrow's video too, since we broke this into two parts because, while the subject matter may be fascinating, we are supposed to hold video lengths down to around 10 minutes, and in this case we still ended up with two videos close to 15 minutes each. And this stuff is important enough that instead of lining up a list of links, we are giving you one link to Google using the search term "rare earths." Yes, we know Rare Earth would be a great name for a rock band. But the mineral rare earths are important in the manufacture of items from strong magnets to touch screens and rechargeable batteries.

KentuckyFC writes: The halting problem is to determine whether an arbitrary computer program, once started, will ever finish running or whether it will continue forever. In 1936, Alan Turing famously showed that there is no general algorithm that can solve this problem. Now a group of computer scientists and ethicists have used the halting problem to tackle the question of how a weaponized robot could decide to kill a human. Their trick is to reformulate the problem in algorithmic terms by considering an evil computer programmer who writes a piece of software on which human lives depend.
The question is whether the software is entirely benign or whether it can ever operate in a way that ends up killing people. In general, a robot could never decide the answer to this question. As a result, autonomous robots should never be designed to kill or harm humans, say the authors, even though various lethal autonomous robots are already available. One curious corollary is that if the human brain is a Turing machine, then humans can never decide this issue either, a point that the authors deliberately steer well clear of.

"Nokia surprised everyone when it announced the N1 Android tablet during the Slush conference in Finland, today. This story has a twist, though: the N1 is not a Nokia device. Nokia doesn't have a device unit anymore: it sold its Devices and Services business to Microsoft in 2013. The N1 is made by Taiwanese contract manufacturing company Foxconn, which also manufactures the iPhone and the iPad.
But Nokia's relationship with Foxconn is different from Apple's. You buy iDevices from Apple, not Foxconn; you call Apple for support, not Foxconn. You never deal with Foxconn. In the case of N1, Foxconn will be handling the sales, distribution, and customer care for the device. Nokia is licensing the brand, the industrial design, the Z Launcher software layer, and the IP on a running royalty basis to Foxconn.

Lucas123 writes: The cost of rooftop solar-powered electricity will be on par with prices of coal-powered energy and other conventional sources in all 50 U.S. states in just two years, a leap from today where PV energy has price parity in only 10 states, according to Deutsche Bank's leading solar industry analyst. The sharp decline in solar energy costs is the result of increased economies of scale leading to cheaper photovoltaic panels, new leasing models and declining installation costs, Deutsche Bank's Vishal Shah stated in a recent report. The cost of solar-generated electricity in the top 10 states for capacity ranges from 11-15 cents per kilowatt hour (c/kWh), compared to the retail electricity price of 11-37 c/kWh. Amit Ronen, a former Congressional staffer behind legislation that created an investment tax credit for solar installations, said one of the only impediments to decreasing solar electricity prices are fees proposed by utilities on customers who install solar and take advantage of net metering, or the ability to sell excess power back to utilities.

MojoKid writes Last week, NVIDIA offered information regarding its Android Lollipop update for the SHIELD Tablet and also revealed a new game bundle for it. This week, NVIDIA gave members of the press early access to the Lollipop update and it will also be rolling out to the general public sometime later today. Some of the changes are subtle, but others are more significant and definitely give the tablet a different look and feel over the original Android KitKat release. Android Lollipop introduces a new "material design" that further flattens out the look of the OS. Google seems to have taken a more minimalist approach as everything from the keyboard to the settings menus have been cleaned up considerably. Many parts of the interface don't have any markings except for the absolute necessities. While the OS definitely feels more fluid and responsive, the default look isn't always better, depending on your personal view. The app tray for example has a plain, white background which looks kind of jarring if you've using a colorful background. And finding the proper touch points for things like a settings menu or clearing notifications isn't always clear. Performance-wise, NVIDIA's Shield Tablet showed significantly better performance on Lollipop for general compute tasks in benchmarks like Mobile XPRT but lagged behind Kit Kat in graphics performance slightly, which could be attributed to driver optimization.

MojoKid writes: For the past year, Intel has pursued what's known as a "contra-revenue" strategy in its mobile division, where product is deliberately sold at a loss to win market share and compete effectively. This has led to a huge rise in tablet shipments, but heavy losses inside Intel's mobile division. Today, the company announced that it would take steps to fold its mobile and conventional processors into a single operating division. While this helps shield the mobile segment from poor short-term results, it also reflects the reality that computing is something users now do across a wide range of devices and multiple operating systems. Intel may not have hit anything like the mobile targets it set out years ago, but long-term success in laptops, tablets, and smartphones remains integral to the company's finances. Desktops and conventional laptops are just one way people compute today and Intel needs to make certain it has a robust long-term presence in every major computing market.

aesoteric writes: Australian researchers have programmed industrial robots to tackle the vast array of e-waste thrown out every year. The research shows robots can learn and memorize how various electronic products — such as LCD screens — are designed, enabling those products to be disassembled for recycling faster and faster. The end goal is less than five minutes to dismantle a product.

mikejuk writes The nematode worm Caenorhabditis elegans (C. elegans) is tiny and only has 302 neurons. These have been completely mapped, and one of the founders of the OpenWorm project, Timothy Busbice, has taken the connectome and implemented an object oriented neuron program. The neurons communicate by sending UDP packets across the network. The software works with sensors and effectors provided by a simple LEGO robot. The sensors are sampled every 100ms. For example, the sonar sensor on the robot is wired as the worm's nose. If anything comes within 20cm of the 'nose' then UDP packets are sent to the sensory neurons in the network. The motor neurons are wired up to the left and right motors of the robot. It is claimed that the robot behaved in ways that are similar to observed C. elegans. Stimulation of the nose stopped forward motion. Touching the anterior and posterior touch sensors made the robot move forward and back accordingly. Stimulating the food sensor made the robot move forward. The key point is that there was no programming or learning involved to create the behaviors. The connectome of the worm was mapped and implemented as a software system and the behaviors emerge. Is the robot a C. elegans in a different body or is it something quite new? Is it alive? These are questions for philosophers, but it does suggest that the ghost in the machine is just the machine. The important question is does it scale?

MojoKid (1002251) writes One of the disadvantages to buying an Apple system is that it generally means less upgrade flexibility than a system from a traditional PC OEM. Over the last few years, Apple has introduced features and adopted standards that made using third-party hardware progressively more difficult. Now, with OS X 10.10 Yosemite, the company has taken another step down the path towards total vendor lock-in and effectively disabled support for third-party SSDs. We say "effectively" because while third-party SSDs will still work, they'll no longer perform the TRIM garbage collection command. Being able to perform TRIM and clean the SSD when it's sitting idle is vital to keeping the drive at maximum performance. Without it, an SSD's real world performance will steadily degrade over time. What Apple did with OS X 10.10 is introduce KEXT (Kernel EXTension) driver signing. KEXT signing means that at boot, the OS checks to ensure that all drivers are approved and enabled by Apple. It's conceptually similar to the device driver checks that Windows performs at boot. However, with OS X, if a third-party SSD is detected, the OS will detect that a non-approved SSD is in use, and Yosemite will refuse to load the appropriate TRIM-enabled driver.
