Smivs writes with this interesting piece of computer history, excerpted from the BBC: "Britain's oldest original computer, the Harwell, is being sent to the National Museum of Computing at Bletchley where it is to be restored to working order. The computer, which was designed in 1949, was built and used by staff at the Atomic Energy Research Establishment in Harwell, Oxfordshire. It first ran in 1951 and was designed to perform mathematical calculations. It lasted until 1973. When first built the 2.4m x 5m computer was state-of-the-art, although it was superseded by transistor-based systems. The restoration project is expected to take a year. Although not the first computer built in the UK, the Harwell had one of the longest service lives. Built by a team of three people, the device was capable of doing the work of six to ten people and ran for seven years until the establishment obtained their first commercial computer. 'We didn't think we were doing anything pioneering at the time,' said Dick Barnes, who helped build the original Harwell computer."

KentuckyFC writes "Sodium acetate is the stuff inside chemical handwarmers that emits heat when it crystalizes after you press that little metal widget. That's why it is known as hot ice. Now a computer scientist in the UK has created a computer made entirely out of hot ice. The device processes information by exploiting the movement and interaction of wavefronts of crystallisation as they move through the material. The data input is in the form of metal wires that trigger crystal nucleation. The output works by reading off the direction of the moving wavefronts and the edges of the resulting crystals. The researcher has created AND and OR gates and solved a few problems such as finding the shortest path through mazes. There are even a few videos of the computer in action. The resulting computer is far from perfect, however. The data readout sometimes gives no solution and at other times gives circular results, the hot ice equivalent of a BSOD."

Chris Pirazzi writes "Online backup startup BackBlaze, disgusted with the outrageously overpriced offerings from EMC, NetApp and the like, has released an open-source hardware design showing you how to build a 4U, RAID-capable, rack-mounted, Linux-based server using commodity parts that contains 67 terabytes of storage at a material cost of $7,867. This works out to roughly $117,000 per petabyte, which would cost you around $2.8 million from Amazon or EMC. They have a full parts list and diagrams showing how they put everything together. Their blog states: 'Our hope is that by sharing, others can benefit and, ultimately, refine this concept and send improvements back to us.'"

Mike writes "Japan has announced plans to send a $21 billion solar power generator into space that will be capable of producing one gigawatt of energy, or enough to power 294,000 homes. The project recently received support from Mitsubishi Electric Corp. and IHI Corp, who are now teaming up in the race to develop new technology within four years that can beam electricity back to Earth without the use of cables. Japan hopes to test a small solar satellite decked out with solar panels by the year 2015."

Mike writes to tell us that Inhabitat has an interesting article, complete with some pretty pictures, about a new solar-powered swarm robot that could be used to collect data and aid in surveillance. "These mini-robots are quite revolutionary, considering that they contain all that's necessary to collect data and relay it back using one single circuit board. In the past single-chip robots have presented significant design and manufacturing challenges due in part to the use of solder as an adhesive. These new microbots use conductive adhesive to attach the components to a double-sided flexible printed circuit board using surface mount technology. The circuit is then folded into thirds and wrapped around the ASIC (application-specific integrated circuit). On top, a solar cell generates power for the robot and delivers 3.6 V to the unit, which is enough for it to walk. Locomotion is achieved via three vibrating legs, while a fourth horizontal vibrating leg is used as a touch sensor."

T Murphy writes "Wind farms can appear like storms or tornadoes on Doppler radar when placed too close to the radar. Tornado alley is a good area for wind farms, and good terrain for the turbines is also ideal for Doppler radar. With many new farms being constructed, the problem is growing. A false tornado warning was issued in Kansas by a computer, although canceled by a meteorologist aware of the problem — there are fears that false positives will grow. Worse would be a tornado ignored as a wind turbine. While meteorologists are trying to work with wind farm owners to shut off the turbines during bad weather, they have no control over the placement or operation of the turbines. Efforts are being made to improve detection technology to avoid further problems."

quacking duck writes "With the release of Mac OS X 10.6 Snow Leopard, Apple has updated a support document describing how their new operating system reports capacities of hard drives and other media. It has sided with hard drive makers, who for years have advertised capacities as '1 GB = 1,000,000,000 bytes' instead of the traditional computer science definition, and in so doing has kicked the debate between marketing and computer science into high gear. Binary prefixes for binary units (e.g. GiB for 'gibibyte') have been promoted by the International Electrotechnical Commission and endorsed by IEEE and other standards organizations, but to date there's been limited acceptance (though manufacturers have wholeheartedly accepted the 'new' definitions for GB and TB). Is Apple's move the first major step in forcing computer science to adopt the more awkward binary prefixes, breaking decades of accepted (if technically inaccurate) usage of SI prefixes?"

mikee805 writes "Solar Roadways, a project to replace over 25,000 square miles of road in the US with solar panels you can drive on, just received $100,000 in funding from the Department of Transportation for the first 12ft-by-12ft prototype panel. Each panel consists of three layers: a base layer with data and power cables running through it, an electronics layer with an array of LEDs, solar collectors and capacitors, and finally the glass road surface. With data and power cables, the solar roadway has the potential to replace some of our aging infrastructure. With only 15% efficiency, 25,000 square miles of solar roadways could produce three times what the US uses annually in energy. The building costs are estimated to be competitive with traditional roads, and the solar roads would heat themselves in the winter to keep snow from accumulating."

Gianna Borgnine writes "NVIDIA is predicting that GPU performance is going to increase a whopping 570-fold in the next six years. According to TG Daily, NVIDIA CEO Jen-Hsun Huang made the prediction at this year's Hot Chips symposium. Huang claimed that while the performance of GPU silicon is heading for a monumental increase in the next six years — making it 570 times faster than the products available today — CPU technology will find itself lagging behind, increasing to a mere 3 times current performance levels. 'Huang also discussed a number of "real-world" GPU applications, including energy exploration, interactive ray tracing and CGI simulations.'"

Underholdning writes "With the DOJ approving Oracle's Sun buyout, the question arises what Oracle might want to do with Sun's hardware business. It's no secret that what Oracle wanted was the software part. Now The Inquirer is running a story claiming that Oracle will sell the hardware business of Sun to HP. This will give Oracle a juicy check while HP can increase its services. Larry Ellison denies that it will take place, but a source for CNN claims otherwise."

itwbennett writes "The FBI is trying to find out who is sending laptops to state governors across the US, including the governors of Wyoming and West Virginia. The West Virginia laptops were delivered to the governor's office on August 5, according to the Charleston Gazette, which first reported the story. Kyle Schafer, West Virginia's chief technology officer, says he doesn't know what's on the laptops, but he handed them over to the authorities. 'Our expectation is that this is not a gesture of good will,' he said. 'People don't just send you five laptops for no good reason.'"

Slatterz writes "We might sometimes complain about the limitations of today's technology, but there's nothing like seeing photos of a 27Kg hard drive with a capacity of 5MB to put things into perspective. PC Authority has toured the Computer History Museum in California, and has posted these fascinating photos, including monster 27Kg and 60Kg drives, and a SAGE air-defense system. Each SAGE housed an A/N FSQ-7 computer, which had around 60,000 vacuum tubes. IBM constructed the hardware, and each computer occupied a huge amount of space. From its completion in 1954 it analyzed radar data in real-time, to provide a complete picture of US Airspace during the cold war. Other interesting photos and trivia include some giant early IBM disc platters, and pics of a curvaceous Cray-1 supercomputer, built in 1972. It was the fastest machine in the world until 1977 and an icon for decades. It cost a mere $6 million, and could perform at 160MFLOPS — which your phone can now comfortably manage."

destinyland writes "A new pogo stick jumps nine feet using legs developed for running robots. (It replaces the stick's spring with a fiber-reinforced 'bow' that was developed at Carnegie Mellon's Robotics institute.) One scientist even suggests robots could use its 'BowGo' technology in the low-gravity environment of the moon. 'Hopping many meters above ground level, the robot would have an excellent view of the terrain.'"

Talinom writes "AnandTech has a writeup on how ClearQAM appears to be headed for an early death. From the article — 'At this point there's no reason to believe that cable companies won't deploy Privacy Mode across their networks, so it's a matter of 'when,' not 'if' this will happen. It goes without saying that if you're currently enjoying the use of a ClearQAM tuner to receive EB tier channels, you'll want to enjoy what time you have left, and look in to other solutions for the long-haul. At this pace, it looks like cable TV and computers will soon be divorcing.'" Update: 08/27 23:59 GMT by T : "EB" here stands for "Expanded Basic (cable service)"; Wikipedia as usual has a time-sucking, digressive, fascinating explanation about the tiers of cable TV service in the US.

carusoj writes "Computer scientists in Japan say they've developed a way to break the WPA encryption system used in wireless routers in about one minute. Last November, security researchers first showed how WPA could be broken, but the Japanese researchers have taken the attack to a new level. The earlier attack worked on a smaller range of WPA devices and took between 12 and 15 minutes to work. Both attacks work only on WPA systems that use the Temporal Key Integrity Protocol (TKIP) algorithm. They do not work on newer WPA 2 devices or on WPA systems that use the stronger Advanced Encryption Standard (AES) algorithm."

blackbearnh writes "With the release of the 3.1 iPhone OS, application developers will finally be able to develop augmented reality (AR) apps. In other words, Terminator Vision is right around the corner. O'Reilly Media recently talked to Chetan Damani, one of the founders of Acrossair, about how they developed their new AR application, Nearest Tube, which displays the closest London Tube stations over a live video overlay on an iPhone 3GS. According to Damani, developing AR applications on the 3GS is dead easy, and the real trick will be developing good augmented reality apps. 'It's all about who's going to have the most amount of data and the most valid data. So there's the obvious types of apps which you're going to launch and those are the find me my nearest bar, find me my nearest event, find me the nearest tube stop, find me the nearest ATM. And those sorts of apps are all going to be around. But they're only going to be useful for when you're trying to look for things. So if we want to get users to use augmented reality a little bit more, we have to start introducing other bits of functionality, things like show me the offers available in a particular high street. Show me when I'm walking down a high street if there's a table available at a particular restaurant. And it's that sort of interactivity and providing that real-time data in this augmented reality view which is going to start getting people to use it a lot more rather than just for show me where the nearest area is.'"

Siliconera found patent filings from Nintendo for a football controller addon that will work with the Wii. After tucking the Wii Remote into a lateral slot on the football, you slip your hand through a strap so that your fingers touch the Remote's buttons. Then you mimic running and throwing, which is interpreted by the accelerometer. 'The pitch angle and force of the throw determines the trajectory arc of the throw. Side to side motion determines the yaw angle. Pressing buttons on the Wii remote can adjust other options.' The device is described as 'squishy,' so your TV is probably safe, but I'd try it at a friend's house first.

Agg writes "Well the slab gets poured on Wednesday so I thought I would sink 6 meters of copper pipe in the slab so that I can run my water loop through it when the house is finished. I hope to have water year round at about 16deg [about 61F]. No need for radiators or fans with chilled water coming straight out of the slab!"

angry tapir writes "At the Hot Chips conference at Stanford University, Sun presented plans for a security accelerator chip that it said would reduce encryption costs for applications such as VoIP calls and online banking Web sites. The coprocessor will be included on the same silicon as Rainbow Falls, the code name for the follow-on to Sun's multi-threaded Ultrasparc T2 processor."

Hugh Pickens writes "Foreign Policy magazine reports that a research team from the SINTEF Group, an independent Norwegian think tank, has warned oil companies worldwide that offshore oil rigs are highly vulnerable to hacking as they shift to unmanned robot platforms where vital operations — everything from data transmission to drilling to sophisticated navigation systems that maintain the platform's position over the wellhead — are controlled via wireless links to onshore facilities. 'The worst-case scenario, of course, is that a hacker will break in and take over control of the whole platform,' says Martin Gilje Jaatun, adding that it hasn't happened yet, but computer viruses have caused personnel injuries and production losses on North Sea platforms. The list of potential cyberattackers includes ecowarriors aiming to jack up an oil firms' production costs, extortionists drawn to oil firms' deep pockets, and foreign governments engaging in a strategic contest for ever-more-scarce global oil reserves, says Jeff Vail, a former counterterrorism and intelligence analyst with the US Interior Department. 'It's underappreciated how vulnerable some of these systems are,' says Vail. 'It is possible, if you really understood them, to cause catastrophic damage by causing safety systems to fail.'"
