mikejuk writes "The Raspberry Pi might be a cheap and reasonably powerful but it has a tough learning curve due to the Linux OS it uses. Adafruit, better known for their hardware, are working on a WebIDE which you can use to program the Pi without having to set things up. You write the code in a browser and run it on the Pi using a web server hosted by the Pi. It sounds crazy but if it can make the Pi more approachable then perhaps it could turn out to be an educational powerhouse."

The Hacker News describes how the username and password system used by Virgin Mobile to let users access their account information is inherently weak and open to abuse." Computerworld also describes the problem: essentially, hard-coded, brute-force guessable passwords, coupled with an inadequate mechanism for reacting to failed attempts to log on.
angry tapir writes "Researchers at the University of New South Wales in Australia have created the world's first working quantum bit based on a single atom in silicon. The research team was able to both read and write information using the spin, or magnetic orientation, of an electron bound to a single phosphorous atom embedded in a silicon chip. In February, UNSW researchers revealed they had successfully created a single-atom transistor using a single phosphorous atom in a silicon crystal."
Nerval's Lobster writes "The Open Compute Project has published the final specification of the Open Rack Specification, which widens the traditional server rack to more than 23 inches. Specifically, the rack is 600 mm wide (versus the 482.6 mm of a 19-inch rack), with the chassis guidelines calling for a width of 537 mm. All told, that's slightly wider than the 580 mm used by the Western Electric or ETSI rack. The Open Compute Project said that changes in the new 1.0 specification include a new focus on a single-column rack design. The new dimensions now accommodate hotter inlet temperatures of between 18 to 35 degrees Celsius and up to 90 percent humidity, which reflects other Open Compute designs and real-world data center temperatures, according to project documents. Facebook has led the implementation of the Open Compute Project, which publicly shares the designs it uses in data centers, including its Prineville, Ore. facility. As the spec clearly shows, however, the new designs deviate from the traditional configurations and specifications, which means data center operators will need to find and then source racks from third-party vendors (or, in the case of Facebook, design their own)."
hypnosec writes "The Raspberry Pi, which was recently used to build a cluster, has officially been given a 'Turbo Mode' by The Raspberry Pi Foundation, thus enabling overclocking. It will bump the frequency of the on-board processor as high as 1GHz as long as the temperature stays below 85C. The patch would dynamically increase the voltage and frequency of the core until the thermals hold. According to the Foundation, users have the option of choosing one of five peak frequencies, the highest being 1GHz."

MrSeb writes with news about our coming cybernetic overlords. From the article: "After more than four years of research, DARPA has created a system that successfully combines soldiers, EEG brainwave scanners, 120-megapixel cameras, and multiple computers running cognitive visual processing algorithms into a cybernetic hivemind. Called the Cognitive Technology Threat Warning System (CT2WS), it will be used in a combat setting to significantly improve the U.S. Army's threat detection capabilities. There are two discrete parts to the system: The 120-megapixel camera, which is tripod-mounted and looks over the battlefield; and the computer system, where a soldier sits in front of a computer monitor with an EEG strapped to his head, looking at images captured by the camera, wedding out false threats. In testing, the 120-megapixel camera, combined with the computer vision algorithms, generated 810 false alarms per hour; with a human operator strapped into the EEG, that drops down to just five false alarms per hour. The human brain is surprisingly fast, too: According to DARPA, CT2WS displays 10 images per second to the human operator — and yet that doesn't seem to affect accuracy."

Today, the devices have been rooted." Using a known bug in busybox dating to April even.
An anonymous reader writes "An achievement that would have extraordinary energy and defense implications might be near at Sandia National Laboratories. The lab is testing a concept called MagLIF (Magnetized Liner Inertial Fusion), which uses magnetic fields and laser pre-heating in the quest for energetic fusion. A paper by Sandia researchers that was accepted for publication states that the Z-pinch driven MagLIF fusion could reach 'high-gain' fusion conditions, where the fusion energy released greatly exceeds (by more than 1,000 times) the energy supplied to the fuel."

An anonymous reader writes "I am tasked with developing a service project to teach students in a Bangladeshi village how to type. The school has about 500 students, 12 computers donated to them in 2006, and a limited electricity supply. The students will be given job placement opportunities at a local firm in the city once they reach a certain proficiency. Therefore, we are trying to teach as many of them typing skills as possible. The problem: limited electricity, limited computers, many kids. I have some additional funding collected through donations. Instead of buying more computers, I am looking for a cost effective way that does not need a steady flow of electricity. I realize that to teach typing, I do not need a computer. I could achieve the same using a keyboard connected to a display. A solar powered calculator is a perfect example of a cheap device which has a numpad for input and an LCD for display. But so far I have not come across a device that has a qwerty keyboard and an LCD to display what's typed. I know there are some gaming keyboards that have LCDs built in but they are quite expensive. I am aiming to build a device that cost below USD 50. I considered using typewriters but they are in limited supply on the market. I also considered OLPC but it is double my anticipated budget. Do you have other suggestions?" Considering that (at least in China) sub-$50 Android tablets with capacitive screens are already here, I wish the Alphasmart line was cheaper, but apparently it currently starts at $169.
MrSeb writes "If, like me, you thought Microsoft would price Windows RT competitively, you were wrong: A leaked slide from Asus says that its Vivo Tab RT, due to be released alongside Windows RT at the end of October, will start at $600. Unbelievably, this is $100 more than the iPad 3, and a full $200 more than the iPad 2 or Galaxy Tab 2 10.1. For $600, you would expect some sensational hardware specs — but alas, that's sadly not the case. The Vivo Tab RT has a low-res 10.1-inch 1366×768 IPS display, quad-core Tegra 3 SoC, 2GB of RAM, NFC, 8-megapixel camera and that's about it. Like its Androidesque cousin, the Transformer, the Vivo Tab RT can be plugged into a keyboard/battery dock — but it'll cost you another $200 for the pleasure. (Curiously, the Transformer's docking station only costs $150 — go figure.)"
First time accepted submitter moon_unit2 writes "Technology Review has the scoop on a new industrial robot created by famed robotics researcher Rodney Brooks. The robot, Baxter, is completely safe, extremely adaptable, and ridiculously easy to program. By providing a way to automate simple manufacturing work, it could help make U.S. manufacturers compete with Chinese companies that rely on low-cost human labor. You can see the new robot in action in a related video of the robot in action and Brooks discussing its potential." $22 thousand and shipping next month, goes the story.
MojoKid writes "Intel's next-generation CPU architecture, codenamed Haswell, puts heavy emphasis on reducing power consumption. Pushing Haswell down to a 10W TDP is an achievement, but hitting these targets requires collaboration. Haswell will offer finer-grained control over areas of logic that were previously either on or off, up to and including specific execution units. These optimizations are impressive, particularly the fact that idle CPU power is approaching tablet levels, but they're only part of the story. Operating system changes matter as well, and Intel has teamed up with Microsoft to ensure that Windows 8 takes advantage of current and future hardware. Haswell's 10W target will allow the chip to squeeze into many of the convertible laptop/tablet form factors on display at IDF, while Bay Trail, the 22nm, out-of-order successor to Clover Trail, arrives in 2013 as well. Not to mention the company's demonstration of the first integrated digital WiFi radio. Folks have been trading blows over whether Intel could compete with ARM's core power consumption. Meanwhile, Santa Clara has been busy designing many other aspects of the full system solution for low power consumption and saving a lot of wattage in the process." It's mildly amusing that Windows 8 is the first version to gain dynamic ticks, something Linux has had working since around 2007.
