storagedude sends in an article claiming that RAID is nearing the end of the line because of soaring rebuild times and the growing risk of data loss. "The concept of parity-based RAID (levels 3, 5 and 6) is now pretty old in technological terms, and the technology's limitations will become pretty clear in the not-too-distant future — and are probably obvious to some users already. In my opinion, RAID-6 is a reliability Band Aid for RAID-5, and going from one parity drive to two is simply delaying the inevitable. The bottom line is this: Disk density has increased far more than performance and hard error rates haven't changed much, creating much greater RAID rebuild times and a much higher risk of data loss. In short, it's a scenario that will eventually require a solution, if not a whole new way of storing and protecting data."

darthcamaro writes "A lot of people in the US have not seen a use case for the use of IPv6 yet, since we've got plenty of IPv4 addresses. But what happens when the entire electrical grid gets smart? The so-called Smart Grid will need a networking transport mechanism that will connect potentially hundreds of millions of people and devices. Networking giant Cisco sees IP (internet protocol) as the right transport and IPv6 as the logical choice for addressing. 'Pv6 is an interesting discussion and one that occupies a lot of bandwidth at Cisco,' Marie Hattar, Cisco's vice president of network systems and security solutions marketing said. 'Some people say that for smaller deployments, we could get away with IPv4, but the smart grid has a number of parts. The point is that if you're looking to build this [smart grid] out, why not build it out on the scalable protocol from the get-go?'"

SpaceGhost writes "The Houston Chronicle has a story on a Grad student at the University of Houston who has designed a cardboard case for a computer. This is not a new concept, but this one is meant to be used in manufacture. The idea is that it will be faster and easier to produce (no fasteners for example) and dramatically easier to recycle."

Mike writes "Today Washington DC-based company Envion opened a $5 million dollar facility that they claim will be able to efficiently transform plastic waste into a source of oil-like fuel. The technology uses infra-red energy to remove hydrocarbons from plastic without the use of a catalyst, transforming 82% of the original plastic material into fuel. According to Envion, the resulting fuel can then be blended with other components, providing a source for gasoline or diesel at as low as $10 per barrel."

Neilio writes "What systems would Slashdotters recommend for staying connected while RV'ing across the US and Canada? While a 3G data plan seems obvious, the intrepid RV'er wants to get remote and into those parts of the coverage map that are usually gray (no coverage). But satellite can be expensive, includes high latency for VoIP and gaming, and requires a clear view of the southern sky. I've come across some intriguing products that use an amplified 2G/3G signal and bridge to WiFi, like WiFi In Motion, and CradlePoint's MBR1000 (I have no affiliation with either). Do folks have any experience with these, or can you recommend another approach (even homebrew)? While I am an electrical engineer by degree, you have to go back a few decades since I last expertly sported a soldering iron, so the less DIY the better. My wife and I now run a web-based business, so nearly daily connectivity is a must, no matter where we are."

TechCrunch has an article about a startup called iMo, which aims to enable control of any PC game using an iPhone or iPod Touch. The idea is to reduce the need for gaming peripherals while you're on the move, and make motion-control available to more players. Quoting: "The system also features onscreen controls for the iPhone and iPod Touch, as not every PC game will benefit from using things like the accelerometer, obviously. This all works via both Bluetooth and WiFi connections between your device and your computer. The plan is to offer iMo in the App Store for $0.99; the first version should be available new in the App Store. And long-term, the company hopes to make it available on other mobile platforms as well, including Android. And ultimately, they'd love to include support for gaming consoles as well, like the aforementioned Wii, the PS3, and the Xbox 360."

Barence writes "British chip designer ARM is launching an outright attack on Intel with the launch of a 2GHz processor aimed at everything from netbooks to servers. ARM claims the 40nm Cortex A9 MPCore processor represents a shift in strategy for the company, which has until now concentrated on low-power processors for mobile devices. In the consumer market, ARM is pitching the Cortex A9 directly against Intel's Atom, claiming the processor offers five times the power while drawing comparable amounts of energy. 'It's head and shoulders above anything Intel can deliver today,' ARM VP of marketing Eric Schom claims. However, it has one major hurdle to overcome: it doesn't support Windows. 'We've had conversations with Microsoft and you can imagine what they entail,' says Schom."

CWmike writes "The US Department of Homeland Security is looking at a report by a research scientist in China that shows how a well-placed attack against a small power subnetwork could trigger a cascading failure of the entire West Coast power grid. Jian-Wei Wang, a network analyst at China's Dalian University of Technology, used publicly available information to model how the West Coast grid and its component subnetworks are connected. Wang and another colleague then investigated how a major outage in one subnetwork would affect adjacent subnetworks. New Scientist magazine reported on this a week or so ago, and the paper has been available since the spring."

andylim writes "Recombu.com has pitted the iPod Nano's video capabilities against an iPhone 3GS, a Nokia 5530 XpressMusic and Flip Mino HD. This simple test shows how the camera deals with motion, colour and audio. The iPod Nano's camera seems to offer a basic yet decent video experience and some might say delivers a higher picture quality than the iPhone 3GS's camera. What's interesting is how well it deals with close-ups."

Xbm360 writes "A report from researcher Canalys said 13.5 million netbooks were sold globally in the 1st half of 2009. Telecom companies have several bundling deals, with about 50 operators selling netbooks. The success of netbooks also surprised Microsoft & forced them to lower the prices of their XP Home licenses, to regain marketshare over Linux."

WARM3CH writes "AnandTech tested a laptop with an AMD CPU, a laptop with an Intel CPU, and a netbook to compare battery life while running Internet Explorer 8, Opera 10, Firefox 3.5, Safari 4, and Chrome. They tested on simple web pages and flash-infested ones. IE8 had the best battery life on both laptops (followed by FF + AdBlock), and Safari had the worst battery life. On the netbook, Chrome was slightly ahead of IE8. The report concludes: 'Overall, Internet Explorer and Firefox + AdBlock consistently place near the top, with Chrome following closely behind. Opera 10 Beta 3 didn't do as well as Opera 9.6.4, and in a couple quick tests, it doesn't appear that the final release of Opera 10 changes the situation at all. Opera in general — version 9 or 10 — looks like it doesn't do as well as the other major browsers. Safari is at the back, by a large margin, on all three test notebooks. We suspect that Safari 4 does better under OS X, however, so the poor Windows result probably won't matter to most Safari users.'"

An anonymous reader writes "Two MIT students have successfully photographed the earth from space on a strikingly low budget of $148. Perhaps more significantly, they managed to accomplish this feat using components available off-the-shelf to the average layperson, opening the door for a new generation of amateur space enthusiasts. The pair plan to launch again soon and hope that their achievements will inspire teachers and students to pursue similar endeavors."

elyons sends word out of UCLA of a completely unexpected discovery in the physics of the Sun-Earth interaction — a previously unknown basic mode of energy transfer from the solar wind to the Earth's magnetosphere. "'It's like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down,' said Larry Lyons, UCLA professor of atmospheric and oceanic sciences. 'We all have thought for our entire careers — I learned it as a graduate student — that this energy transfer rate is primarily controlled by the direction of the interplanetary magnetic field. The closer to southward-pointing the magnetic field is, the stronger the energy transfer rate is, and the stronger the magnetic field is in that direction. [It turns out that] if it is both southward and big, the energy transfer rate is even bigger.'" The researchers have two papers on the discovery coming out in the Journal of Geophysical Research.

adeelarshad82 writes with this excerpt from a Reuters report: "Google is disappointed with the lack of breakthrough investment ideas in the green technology sector, but the company is working to develop its own new mirror technology that could reduce the cost of building solar thermal plants by [25%] or more. The company's engineers have been focused on solar thermal technology, in which the sun's energy is used to heat up a substance that produces steam to turn a turbine. Mirrors focus the sun's rays on the heated substance. ... Google hopes to have a viable technology to show internally in a couple of months, Bill Weihl said. It will need to do accelerated testing to show the impact of decades of wear on the new mirrors in desert conditions."

The folks at The Register have gotten their hands on Sun's confidential roadmap from June, which outlines the company's plans for SPARC product lines. The chart has some basic technical details for the UltraSPARC T-series and the SPARC64 line. The long-anticipated "Rock" line is not mentioned. "We can expect a goosed SPARC64-VII+ chip any day now, which will run at 2.88 GHz and which will be a four-core, eight-threaded chip like its 'Jupiter' predecessor. This Jupiter+ chip is implemented in the same 65 nanometer process as the Jupiter chip was, and it is made by Fujitsu, a company that is in the process of outsourcing its chip manufacturing to Taiwan Semiconductor Manufacturing Corp. ... not only has Sun cut back on the threads with [the 2010 UltraSPARC model, codenamed Rainbow Falls], it has also cut back on the socket count, keeping it at the same four sockets used by the T5440 server. And instead of hitting something close to 2 GHz as it should be able to do as it shifts from a 65 nanometer to a 45 nanometer process in the middle of 2010, Sun is only telling customers that it can boost clock speeds to 1.67 GHz with Rainbow Falls."

Danny writes to tell us that Obscura Digital has launched their largest multitouch wall yet. 18 feet of multitouch surface is divided to allow six simultaneous users, each with their own targeted audio. The massive wall can handle 100 hi-res images and videos together in real-time. Relatedly, Atmel recently announced the release of their "maXTouch" technology, which delivers a capacitive touchscreen that boasts a refresh rate and signal-to-noise ratio that's 66% better than their nearest competitor. Hopefully this means massive multitouch surfaces will be coming into my home sooner rather than later.

nuur writes "Researchers at the Australian National University have developed a new form of optical memory that allows random access to stored optical quantum information. Pulses of light are stored on a kind of 'optical conveyor-belt' that is controlled with a magnetic field. By manipulating the magnetic field, the conveyor-belt can be moved, allowing the recall of any part of the stored optical information. The research is published in Nature." You'll probably know after reading the abstract linked whether you'd be in the market to pay for the whole thing.

An anonymous reader writes "Most people use MS filesystems on Disk-On-Keys, and portable hard drives, as these are readable from most machines. But this way you lose the files' permission information, which many times is very inconvenient (you must agree that having Ubuntu asking you whether to execute or display every text file or image you open from a DOK is annoying). Using 'regular' Linux filesystems like ext keeps the permissions, but may require using the superuser when switching machines (as the UIDs are different). So do any of you have a creative solution for this problem?"

J. Dzhugashvili writes "Whereas most current graphics cards can only drive a pair of displays, AMD has put some special sauce in its next-generation DirectX 11 GPUs to enable support for a whopping six monitors. There's no catch about supported resolutions, either. At an event yesterday, AMD demonstrated a single next-gen Radeon driving six 30" Dell monitors, each with a resolution of 2560x1600, hooked up via DisplayPort. Total resolution: 7680x3200 (or 24.6 megapixels). AMD's drivers present this setup as a single monitor to Windows, so in theory, games don't need to be updated to support it. AMD showed off Dead Space, Left 4 Dead, World of Warcraft, and DiRT 2 running at playable frame rates on the six displays."

Alison Beasley sends word that GaiKai, the cloud gaming service being developed by games industry vet Dave Perry, is about to begin beta testing in Europe. (Sign-up page.) GaiKai is a competitor to OnLive, which started beta tests of its own recently. IGN got a chance to try out GaiKai for themselves, and they've posted a video showing how it performed. From Perry's announcement: "Our closed beta has two goals. #1 is to bring our servers to their knees so we can choose the final configuration before we start ordering large quantities of them. (We think we have it worked out, but you can be certain our staff will be swapping cards and testing different processors as each day goes by.) Goal #2 is to test older computers. We've had lots of emails from people describing their computers and 99% of them have ample performance. Remember you don't even need a 3D card to see a 3D game run on our service. I know this is strangely counter to what people expect, but we actually want to get plenty of basic office-grade XP machines testing so we can make sure we can reach the widest audience possible. ... After we choose the hardware configuration in Europe, our next phase will be our USA Nationwide Network Test, that will be using 8 Tier-1 Data Centers, getting hammered by Closed Beta testers. During that process, [we] will be identifying the other data centers we need to include to blanket the USA in a low latency array. Phase 2 of that is Europe, in exactly the same test."
