Nerval's Lobster writes "The Apache Hadoop open-source framework specializes in running data applications on large hardware clusters, making it a particular favorite among firms such as Facebook and IBM with a lot of backend infrastructure (and a whole ton of data) to manage. So it'd be hard to blame Intel for jumping into this particular arena. The chipmaker has produced its own distribution for Apache Hadoop, apparently built 'from the silicon up' to efficiently access and crunch massive datasets. The distribution takes advantage of Intel's work in hardware, backed by the Intel Advanced Encryption Standard (AES) Instructions (Intel AES-NI) in the Intel Xeon processor. Intel also claims that a specialized Hadoop distribution riding on its hardware can analyze data at superior speeds—namely, one terabyte of data can be processed in seven minutes, versus hours for some other systems. The company faces a lot of competition in an arena crowded with other Hadoop players, but that won't stop it from trying to throw its muscle around."

AstroPhilosopher writes "In a move not far removed from the model T-101, U.S. researchers have succeeded in re-animating a dead sparrow. Duke scientists were studying male behavior aggression among sparrows. They cleverly decided to insert miniaturized robotics into an empty sparrow carcass and operate it like a puppet (abstract). It worked; they noticed wing movements were a primary sign of aggression. Fortunately the living won out this time. The experiment stopped after the real sparrows tore off the robosparrow's head. But there's always a newer model on the assembly-line. Good luck sparrows." Bad Horse has not yet made a decision on the researchers' application.
Dr. Tom writes "The U.S. has deployed more than 11,000 military drones, up from fewer than 200 in 2002. They carry out a wide variety of missions while saving money and American lives. Within a generation they could replace most manned military aircraft, says John Pike, a defense expert at the think tank GlobalSecurity.org. Pike suspects that the F-35 Lightning II, now under development by Lockheed Martin, might be 'the last fighter with an ejector seat, and might get converted into a drone itself.' The weakest link is the pilot. A jet could pull 15 Gs, out-turning any conventional aircraft, except it would kill the pilot. Is it time to stop spending billions on obsolete aircraft?"
First time accepted submitter AchilleTalon writes "Research by Harvard professor David Keith suggests that the global capacity for energy generation from wind power has been overestimated, and that geophysical / climate effects of turbines will reduce the benefits of large-scale power installations. 'People have often thought there's no upper bound for wind power—that it's one of the most scalable power sources," he says. After all, gusts and breezes don't seem likely to 'run out' on a global scale in the way oil wells might run dry. Yet the latest research suggests that the generating capacity has been overestimated."
adeelarshad82 writes "Needless to say, the march of processor speeds always continues. However, Nvidia Tegra 4's benchmark results are off the charts. Comparing the results against several other phones, it was evident that Tegra 4 will make for the fastest mobile phones yet. For instance when benchmarked against iPhone 5, results showed 1640 on Geekbench and 27 fps on GLBenchmark's Egypt HD offscreen benchmark. Whereas the Tegra 4 scores 4148 on Geekbench and 57 fps on the Egypt HD. Of course, the competition isn't standing still, either. Qualcomm is countering the Tegra 4 with its Snapdragon 800, which the company claims is even faster than the Tegra 4. And at the same time Samsung is readying the Exynos 5 Octa."
New submitter KublaCant writes "'At this very moment, researchers around the world – including in the United States – are working to develop fully autonomous war machines: killer robots. This is not science fiction. It is a real and powerful threat to humanity.' These are the first words of a Human Rights Watch Petition to President Obama to keep robots from the battlefield. The argument is that robots possess neither common sense, 'real' reason, any sense of mercy nor — most important — the option to not obey illegal commands. With the fast-spreading use of drones et al., we are allegedly a long way off from Asimov's famous Three Laws of Robotics being implanted in autonomous fighting machines, or into any ( semi- ) autonomous robot. A 'Stop the Killer Robots' campaign will also be launched in April at the British House of Commons and includes many of the groups that successfully campaigned to have international action taken against cluster bombs and landmines. They hope to get a similar global treaty against autonomous weapons. The Guardian has more about this, including quotes from well-known robotics researcher Noel Sharkey from Sheffield University."
theodp writes "You know the old adage, 'Fool me once, shame on you; fool me twice, shame on me?' Still, even if you got bit by the HP TouchPad debacle, HP's newly-announced $169 Slate7 tablet could prove hard to resist. Specs-wise, the Slate7 sports an ARM Dual Core Cortex-A9 1.6 GHz processor, 7-inch 1024x600 HFFS screen, Android 4.1 (Jellybean), three-megapixel camera on the back, front-facing VGA camera, 8GB of on-board storage, HP ePrint, Beats Audio, and a micro SD expandable card slot. It measures 197mm x 116mm x 10.7mm thick, and weighs in at 13 ounces. It will be available in the U.S. in April. Engadget has some pics and their initial hands-on take."
Barence writes "Are faster grades of SD memory card worth the extra cash? PC Pro has conducted in-depth speed tests on different grades of SD card to find out if they're worth the premium. In camera tests, two top-end SD cards outshone the rest by far, while class 4 cards dawdled for more than a second between shots. However, with the buffer on modern DSLRs able to handle 20 full-res shots or more, it's unlikely an expensive card will make any difference to anyone other than professionals shooting bursts of fast-action shots. What about for expanding tablet or laptop memory? A regular class 4 or 6 card that's capable of recording HD video will also be fast enough to play it back on a tablet. The only advantage of a faster card for media is that syncing with your PC will be quicker. However, a faster card is recommended if you're using it to supplement the memory of an Ultrabook or MacBook Air."
New submitter capsfan100 writes "At Christmas I got an $89 Android tablet by MID. The 7" tablet has sufficient RAM, etc. The battery, however, was rather pathetic out of the box. It's already fading, so we know where this is headed — decent tablet, but it constantly needs the plug. How would you take this 'old' tablet and turn it into a rockin' stereo component? Is there a ROM build out there titled Pimp My Tablet Into An MP3 Player? The current music app can look up lyrics on-line. I'd like to keep that feature. Any ideas on a good app for syncing music videos with my *ahem* random music collection? Any fun, off-beat party apps this middle-aged suburban dad hasn't heard of? Since the Android security nightmare is so well documented, I'd rather not use services that require passwords. I also need top-notch security and monitoring software so I can see what my kids and their friends are doing with it next year when I'm not home while keeping them anonymous and safe on-line. As for my living room stereo system, how best to mount a sleek MP3 tablet? I was thinking velcro, but it would ruin the feel. Maybe a wall-mount arm like my HDTV has? We want to be able to unplug it and move around the room, so I'll need to upgrade the speakers to wireless. Any thoughts there? I'm not afraid of the command line — indeed, I insist on one — but no Gentoo-type projects, thank you. Just a good sleek and secure ROM for optimal tunage with all the top apps the kids are using today."
Press2ToContinue writes with this excerpt from ExtremeTech: "With products like Google's Glass, the Oculus Rift, and even certain features found on the Nintendo 3DS, augmented, mixed, and virtual reality are starting to make some headway in the consumer space. Canon, best known for its cameras, is looking to break into the mixed reality scene with its new head-mounted display. ... The core of the setup is the Canon HMD (head-mounted display) which works in conjunction with various sensors — optical and magnetic, as well as visual markers — to help create the mixed reality environment. The HMD employs two cameras located in front of each eye that captures video and shoots it off to an off-board, tethered computer. The computer then combines the real-world visuals with computer-generated visuals, and beams that back to two monitors placed in front of the eyes within the HMD. The unit combines with a development platform, dubbed the MR Platform, which allows companies to create mixed reality images to display on the HMD."
rtfa-troll writes "There has been a worldwide (all locations) total outage of storage in Microsoft's Azure cloud. Apparently, 'Microsoft unwittingly let an online security certificate expire Friday, triggering a worldwide outage in an online service that stores data for a wide range of business customers,' according to the San Francisco Chronicle (also Yahoo and the Register). Perhaps too much time has been spent sucking up to storage vendors and not enough looking after the customers? This comes directly after a week-long outage of one of Microsoft's SQL server components in Azure. This is not the first time that we have discussed major outages on Azure and probably won't be the last. It's certainly also not the first time we have discussed Microsoft cloud systems making users' data unavailable."
At last year's RSA security conference, we ran into the Pwnie Plug. The company has just come out with a new take on the same basic idea of pen-testing devices based on commodity hardware. Reader puddingebola writes with an excerpt from Wired: "The folks at security tools company Pwnie Express have built a tablet that can bash the heck out of corporate networks. Called the Pwn Pad, it's a full-fledged hacking toolkit built atop Google's Android operating system. Some important hacking tools have already been ported to Android, but Pwnie Express says that they've added some new ones. Most importantly, this is the first time that they've been able to get popular wireless hacking tools like Aircrack-ng and Kismet to work on an Android device." Pwnie Express will be back at RSA and so will Slashdot, so there's a good chance we'll get a close-up look at the new device, which runs about $800.
An anonymous reader writes "For a while now, John Carmack has been pushing to bring virtual reality technology back to the gaming world. VR was largely abandoned over a decade ago when it became apparent that the hardware just wasn't ready to support it. In 2013, things are different; cheap displays with a high pixel density and powerful processors designed for small systems are making virtual reality a... reality. One of the last obstacles to be conquered is latency — the delay between moving your head and seeing your perspective change in the virtual world. In a lengthy and highly-technical post at #AltDevBlogADay, Carmack has outlined a number of strategies for mitigating and reducing latency. With information and experience like this being shared with the game development community at large, it shouldn't be long until VR makes a permanent place for itself in our gaming lives."
eldavojohn writes "A new report from China's environment ministry has resulted in long-overdue self-realizations as well as possible explanations for 'cancer villages.' The term refers to villages (anywhere from 247 to 400 known of them) that have increased cancer rates due to pollution from nearby factories and industry. The report revealed that many harmful chemicals that are prohibited and banned in developed nations are still found in China's water and air. Prior research has shown a direct correlation between industrialization/mining and levels of poisonous heavy metals in water. As a result, an air pollution app has grown in popularity and you can see the pollution from space. China has also released a twelve-year plan for environmental protection."
Nerval's Lobster writes "Earlier this month, a very public argument erupted between Tesla Motors CEO Elon Musk and New York Times reporter John Broder, who claimed in a Feb. 8 column that his electric-powered Model S sedan had ground to a halt on a lonely stretch of Connecticut highway, starved for power. Musk retaliated by publishing the data from Broder's test drive, which suggested the reporter had driven the vehicle at faster speeds than he had claimed in the article (which would have drained the battery at a quicker rate) and failed to fully charge the car at available stations. Musk seems to have let the whole thing drop, but the whole brouhaha raises a point that perhaps deserves further exploration: the rising use of sensors in cars, and whether an automobile company—or any other entity, for that matter—has the right to take data from those sensors and use it for their own ends without the owner's permission. (For his part, Musk has claimed that Tesla only turns on data logging with 'explicit written permission from customers.') What do you think, Slashdot? Do we need the equivalent of a 'Do-Not-Track' option for cars?"
Vigile writes "A big shift in the way graphics cards and gaming performance are tested has been occurring over the last few months, with many review sites now using frame times rather than just average frame rates to compare products. Another unique testing methodology called Frame Rating has been started by PC Perspective that uses video capture equipment capable of recording uncompressed high resolution output direct from the graphics card, a colored bar overlay system and post-processing on that recorded video to evaluate performance as it is seen by the end user. The benefit is that there is literally no software interference between the data points and what the user sees, making it is as close to an 'experience metric' as any developed. Interestingly, multi-GPU solutions like SLI and CrossFire have very different results when viewed in this light, with AMD's offering clearly presenting a poorer, and more stuttery, animation."
derGoldstein writes "We've seen some very impressive aerobatics performed by quadrocopters before, but this is getting ridiculous. Robohub points to the latest advancement from the Flying Machine Arena, which developed algorithms that allow quadrocopters to juggle an inverted pendulum. One of the researchers working on it said, 'We started off with some back-of-the-envelope calculations, wondering whether it would even be physically possible to throw and catch a pendulum. This told us that achieving this maneuver would really push the dynamic capabilities of the system. As it turned out, it is probably the most challenging task we've had our quadrocopters do. With significantly less than one second to measure the pendulum flight and get the catching vehicle in place, it's the combination of mathematical models with real-time trajectory generation, optimal control, and learning from previous iterations that allowed us to implement this.'"
cylonlover writes "If Joseph Zawodny, a senior scientist at NASA's Langley Research Center, is correct, the future of energy may lie in a nuclear reactor small enough and safe enough to be installed where the home water heater once sat. Using weak nuclear forces that turn nickel and hydrogen into a new source of atomic energy, the process offers a light, portable means of producing tremendous amounts of energy for the amount of fuel used. It could conceivably power homes, revolutionize transportation and even clean the environment."
rtoz writes "Ohio State students have come up with a scaled-down version of a power plant combustion system with a unique experimental design--one that chemically converts coal to heat while capturing 99 percent of the carbon dioxide produced in the reaction. Typical coal-fired power plants burn coal to heat water to make steam, which turns the turbines that produce electricity. In chemical looping, the coal isn't burned with fire, but instead chemically combusted in a sealed chamber so that it doesn't pollute the air. This new technology, called coal-direct chemical looping, was pioneered by Liang-Shih Fan, professor of chemical and biomolecular engineering and director of Ohio State's Clean Coal Research Laboratory."

This high-end Chromebook with a 12.85-inch high resolution touchscreen (available in both Wi-Fi only and Verizon LTE versions) and an Intel Core i5 processor under the hood is super fancy, and also super expensive: starting at $1299.
