theodp writes "GeekWire reports on a newly-surfaced Microsoft patent application for 'Targeting Advertisements Based on Emotion', which describes how information gleaned from Kinects, webcams, online games, IMs, email, searches, webpage content, and browsers could be used to build an 'Emotional State Database' of individuals' emotions over time for advertisers to tap into. From the patent application: 'Weight-loss product advertisers may not want their advertisement to appear to users that are very happy. Because, a person that is really happy, is less likely to purchase a self-investment product that leverages on his or her shortcomings. But a really happy person may purchase electronic products or vacation packages. No club or party advertisers want to appear when the user is sad or crying. When the user is emotionally sad, advertisements about club parties would not be appropriate and may seem annoying or negative to the user. Online help or technical support advertisers want their advertisements to appear when the user is demonstrating a confused or frustrated emotional state.'"

New submitter toxygen01 writes "Neal Stephenson, sci-fi writer mostly known for his books Snowcrash and Cryptonomicon, takes on revolutionizing virtual sword fighting with help of crowdfunding. Inspired by the little-known fictional universe of 'Mongoliad,' an interactive book he is collaborating on, his company is trying to develop hardware (low-latency motion controller) and software for realistic medieval sword fighting. From what is promised, it will try to be open for other developers by having API and SDK available for further modding." Very few Kickstarter drives have a steel longsword as one of the rewards for investing.
OceanMan7 writes "My 7-year-old son is getting very interested in microscopic things — from bacteria to parameciums (paramecia?) Not being a biologist, I would appreciate advice on what type of microscope to get. I'd be operating it and he viewing with supervision. I'd like something better than a toy and plan to buy it used, if possible. Extra points if it's stereo and also allows me to view opaque objects at low magnification."
An anonymous reader writes "JEDEC hasn't finalized the upcoming DDR4 standard yet, but it seems they left out licensing some crucial IP for (the already finalized and shipping) LRDIMMs (for use on data center servers). As a result they are only produced by one source which is facing some hurdles justifying their copying of IP. This article discusses how DDR4 is based on LRDIMMs and the future of memory. Quoting: 'JEDEC finalized the LRDIMM standard without securing licensing on load reduction and rank multiplication. Inphi, currently the only maker of LRDIMM buffer chipsets – others have backed off – lost a challenge of Netlist IP at the USPTO. As a result the Netlist patents have become stronger and are going to come back and bite Inphi in Netlist vs. Inphi, which was stayed pending these patent reexaminations – patents which survive re-examination can never again be challenged in court. NLST patents ’537 and ’274 survived with all claims intact, which is a powerful statement on the strength of their IP – Inphi has appealed to the BPAI, but the USPTO decision is telling.'"
ananyo writes "Scientists have reported the first tabletop source of ultra-short, laser-like pulses of low energy, or 'soft,' X-rays. The light, capable of probing the structure and dynamics of molecules (abstract), was previously available only at large, billion-dollar national facilities such as synchrotrons or free-electron lasers, where competition for use of the equipment is fierce. The new device, by husband-and-wife team Margaret Murnane and Henry Kapteyn based at JILA in Boulder, Colorado, might soon lie within the grasp of a university laboratory budget — perhaps allowing them to one day be as common in labs as electron microscopes are."
UnderAttack writes "A common joke in infosec is that you can't hack a server that is turned off. You better make sure that the power cord is unplugged, too. Otherwise, you may be exposed via IPMI, a component present on many servers for remote management that can be used to flash firmware, get a remote console and power cycle the server even after the normal power button has been pressed to turn the server off."
MrSeb writes "Ever since the release of the iPhone 4 with its 326 pixels-per-inch (PPI) Retina display, people have wondered about the lack of high-PPI desktop displays. The fact is, high-resolution desktop displays do exist, but they're incredibly expensive and usually only used for medical applications. Here, ExtremeTech dives into the world of desktop displays and tries to work out why consumer-oriented desktop displays seem to be stuck at 1920x1080, and whether future technologies like IGZO and OLED might finally spur manufacturers to make reasonably-priced models with a PPI over 100."
MrSeb writes "MIT has devised a way of creating complex, self-assembling 3D nanostructures of wires and junctions. While self-assembling structures have been made from polymers before, this is the first time that multi-layer, configurable layouts have been created, opening up the path to self-assembled computer chips. Basically, MIT uses diblock copolymers, which are large molecules formed from two distinct polymers (each with different chemical and physical properties). These copolymers naturally form long cylinders — wires. The key to MIT's discovery is that the scientists have worked out how to exactly control the arrangement of these block copolymers. By growing tiny, 10nm-wide silica 'posts' on a silicon substrate, the researchers can control the angles, bends, spacing, and junctions of the copolymer wires. Once the grid of posts has been built, the wafer is simply covered in the polymer material, and chip's wires and junctions self-assemble. The reason everyone is so excited, though, is that the silica posts can be built using equipment that is compatible with existing semiconductor fabs. Theoretically, chips built using this technique could have a much smaller feature size than the 28nm and 22nm chips produced by TSMC and Intel. According to Caroline Ross of MIT, it should be possible to build posts that are much smaller than 10nm."
jfruh writes "Taipei's Computex trade show has seen an array of strange devices on sale that are somewhere between PCs and tablets: laptops with screens you can twist in every direction, tablets with detachable keyboards, all-in-one PCs with detachable monitors. Some have Intel chips, some ARM chips; some run Windows 8, some Android. They all exist because of the cheap components now available, and because Windows 8 will make touch interfaces possible — but mostly they exist because PC makes are starting to freak out about being left behind by the tablet revolution."

An anonymous reader writes "In spite of Linux's great networking capabilities, there seems to be a shortage of suitable hardware for building an enterprise-grade networking platform. I've had success on smaller projects with the Soekris offerings but they are suboptimal for large-scale deployment due to their single-board non-redundant design (eg., single power supply, lack of backup 'controller'). What is the closest thing to a modular Linux-capable platform with some level of hardware redundancy and substantial bus/backplane throughput?"
MojoKid writes "E3 is well underway in Los Angeles, and Microsoft has already made a major splash with its 'SmartGlass' technology, game demos, and its announcement that a Kinect-powered version of Internet Explorer will debut on the Xbox 360. This is a marked change from last year, when Kinect was the unquestioned centerpiece of Microsoft's display and the company's demos focused on how Kinect-powered games used your full body as a controller. Kinect is in the interesting position of having sold extremely well while failing to move the bar forward in any of the ways Microsoft projected in the run up to its launch. Scroll through the ratings on Kinect-required titles, and the percentages are abysmal. Kinect's biggest problem is rooted in ergonomics. Gamepads with buttons may be crude approximations of real life, but they're simple and intuitive. They're also flexible — a great many games have conditional scenarios that allow the same button to perform different functions depending on what's going on within the game. Pure Kinect games don't have a simple mechanism to incorporate these features, and there's no easy way around them. The motion-controller's most enduring features may ultimately be its capabilities outside the gaming sphere."
An anonymous reader writes "John Carmack, co-founder of id Software, is using his spare time to develop a modern virtual reality headset. After purchasing such a device last year, Carmack became frustrated with how slowly the technology has progressed over the past twenty years. So, he decided to push it forward himself. PCGamer reports that he's been showing off his prototype behind closed doors at E3 this year, and has an interview with him about the problems with VR and the technical challenges he needs to overcome. They even get a look at the prototype itself, which is currently held together with duct tape."

Today the airplane made news again as it successfully completed the world's first solar-powered intercontinental flight — a pivotal step that paves the way for the plane's first trip around the world in 2014."
ananyo writes with a story about more concrete plans for a reduced or nuclear-free energy future for Japan. From the article: "It's official: nuclear power will have a much smaller role in Japan's energy future than was once thought. Since the meltdowns and gas explosions at the Fukushima Daiichi nuclear power station in March 2011, all of Japan's remaining reactors have been shut down for inspections and maintenance. The government offered a glimpse of their future, and that of the country's nuclear power in general, when it published an outline of four ways to satisfy Japan's future energy demands. One scenario recommends using a market mechanism to determine the nuclear contribution. Under the other three, nuclear power would supply at most one-quarter of Japan's energy by 2030 — and in one case, none at all. The scenarios come from a 25-person advisory committee to the industry ministry. The sharp reductions in the nuclear power part of the country's energy mix mean that Japan will struggle to reach the 31% reduction in carbon dioxide emissions that it had planned by 2030 (PDF)."
