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."
garymortimer writes "Raytheon will help the U.S. Navy transition to using Linux software at ground control stations for unmanned air vehicles, the Defense Department announced Wednesday. The company's intelligence and information systems unit won a $27,883,883 contract to implement the tactical control system software, used for directing vertical take-off UAVs."
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."
An anonymous reader writes "Slashdotters may remember the Solar Impulse — the world's first 100% solar-powered airplane — from last year when it made its public debut. 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)."
kkleiner writes "Wouldn't it be awesome if our tablets and smartphones could have buttons that morphed out of the touchscreen, and then went away again when we didn't need them? It sounds like magic, but now it is reality. Created by Tactus Technology, a Fremont, California-based start-up, Tactus is a deformable layer that sits on top of a touchscreen sensor and display. 'The layer is about 0.75mm to 1mm thick, and at its top sits a deformable, clear layer 200 nm thick. Beneath the clear layer a fluid travels through micro-channels and is pushed up through tiny holes, deforming the clear layer to create buttons or shapes. The buttons or patterns remain for however long they are needed, just for a few seconds or for hours when you’re using your iPad to write that novel. And because the fluid is trapped inside the buttons, they can remain for however long without additional power consumption. They come or go pretty quickly, taking only a second to form or disappear.'"
1sockchuck writes "Netflix has launched its own content delivery network to manage data delivery for its streaming video service. ISPs can choose to host caching appliances in their data centers, or peer with Netflix at Internet Exchanges. 'Netflix will provide either form of access at no cost to the ISP,' it said. As part of Open Connect, Netflix is sharing its hardware appliance design and the open source software components of the server. Does this mean Armageddon for the CDNs currently serving Akamai? Not really, according to analysts, citing the leverage Netflix had in dealing with providers."
snowdon writes "The race for low-latency in finance and HPC has taken a major turn. A bunch of engineers from Australia have 'thrown away the air conditioning' in a traditional switch, to get a 10G fibre-to-fibre latency of less than 130ns! Way faster than more traditional offerings. This lady (video) would tell you that it's equivalent to just 26m of optical fibre. Does that mean we just lose money faster?"
MrSeb writes with the scoop on Asus's new Transformer tablet/laptop devices: "If you've ever looked at an Asus Transformer and wished that it was slightly bigger, had an x86 processor, and ran Windows, I have good news: At Computex in Taiwan, Asus has unveiled just that. Dubbed the Transformer Book, this isn't some wimpy Atom-powered thing either: This Transformer will ship with a range of Ivy Bridge Core i3/5/7 processors and discrete Nvidia graphics. Like its Android-powered predecessors, the Transformer Book is a touchscreen tablet computer that plugs into keyboard docking station, effectively becoming a laptop (or ultrabook, if you prefer). Rounding out the specs, the Transformer Book will come in a range of models (11.6, 13, and 14 inches), your choice of SSD or HDD, up to 4GB of RAM. All three models will have an IPS display capable of full HD (1920×1080). There's a webcam on the front of the tablet portion of the Transformer, and a 5-megapixel shooter on the back. There's no mention of wireless connectivity, but presumably there's Bluetooth and WiFi; on the wired side, there seems to be only a single micro-HDMI socket (on the tablet), and a USB socket (on the keyboard/dock). On the software side, the Transformer Book will of course run Windows 8. It all sounds great — but Asus kept one tiny tidbit out of its presentation: battery life." Aside from the Nvidia graphics (which, from the looks of it, can be disabled for the on-chip output), perhaps this could be the first "tablet" capable of running fully Free Software? (UEFI evil aside).
garymortimer writes with news of the test flight of a hydrogen powered UAV. From the article: "Phantom Eye's innovative and environmentally responsible liquid-hydrogen propulsion system will allow the aircraft to stay on station for up to four days while providing persistent monitoring over large areas at a ceiling of up to 65,000 feet, creating only water as a byproduct. The demonstrator, with its 150-foot wingspan, is capable of carrying a 450-pound payload."
Nerval's Lobster writes "NoSQL databases sometimes feature a concept called document storage, a way of storing data that differs in radical ways from the means available to traditional relational SQL databases. But what does 'document storage' actually mean, and what are its implications for developers and other IT pros? This SlashBI article focuses on MongoDB; the techniques utilized here are similar in other document-based databases."
