djk1024 writes "I've just filed for a patent on a new approach to motion capture that is simple, cheap, easy, accurate, and portable. It's RF-based, accurate to 1 mm, and simple enough that a sophisticated hobbyist could build one in a couple weekends from plans and standard electronics. So now what? I quit my job and have been working on this full-time for the past couple of years; now I'm out of money so can't continue development on my own. I'm also not an electrical or RF guy so I can't carry out my own independent development on the electronics. I'm quite frustrated at this point. I've been in the software development field for over 30 years and have gone through a large number of startups, but always just as the head techie, and always as part of a team. This doing it alone sucks. I would love some advice on how best to go forward."

innocent_white_lamb writes "The Canadian Private Copying Collective is pushing for the implementation of an iPod fee in Canada to compensate them for 'losses' when people copy music to their digital music players. They have collected a fee from every CDR sold in Canada since 1997 and now want to extend that to digital music players. From the article: 'Some have argued that once they buy a CD they shouldn't have to pay again and again to listen to those songs — which they already purchased — on a personal compilation CD or on their MP3 player. But for people like Milman and Basskin, it's about recognizing the value of those works. "There has to be some sort of way to compensate the artist for the hours and the sweat and the blood and the tears and the extreme, extreme expense that goes into making music," Milman said.'"

The Digital Foundry blog has an article about measuring an important but often nebulous aspect of console gameplay: input lag. Using a video camera and a custom input monitor made by console modder Ben Heck, and after calibrating for display lag, they tested a variety of games to an accuracy of one video frame in order to determine the latency between pressing a button and seeing its effect on the screen. Quoting: "If a proven methodology can be put into place, games reviewers can better inform their readers, but more importantly developers can benefit in helping to eliminate unwanted lag from their code. ... It's fair to say that players today have become conditioned to what the truly hardcore PC gamers would consider to be almost unacceptably high levels of latency to the point where cloud gaming services such as OnLive and Gaikai rely heavily upon it. The average videogame runs at 30fps, and appears to have an average lag in the region of 133ms. On top of that is additional delay from the display itself, bringing the overall latency to around 166ms. Assuming that the most ultra-PC gaming set-up has a latency less than one third of that, this is good news for cloud gaming in that there's a good 80ms or so window for game video to be transmitted from client to server."

angry tapir writes "The San Diego Supercomputer Center has built a high-performance computer with solid-state drives, which the center says could help solve science problems faster than systems with traditional hard drives. The flash drives will provide faster data throughput, which should help the supercomputer analyze data an 'order of magnitude faster' than hard drive-based supercomputers, according to Allan Snavely, associate director at SDSC. SDSC intends to use the HPC system — called Dash — to develop new cures for diseases and to understand the development of Earth."

The big news about game consoles of late are the recent price drops and hardware changes. However, an editorial at GamesIndustry looks into one of the side effects of those updates: decisions by both Microsoft and Sony not to include HDMI cables with their HD-capable consoles, despite the companies' long-standing interest in high-definition gaming. "From the perspectives of these companies, they want to include the cable which will be of most utility to the largest group of consumers possible, and it's clear that whatever research they have done suggests that the majority of consumers don't need — or rather, can't use — an HDMI cable. Neither firm wants to put an assortment of cables in the box 'just in case' — each additional cable erodes millions from the firm's profitability, after all. ... Supporting evidence that all is not well with the HD transition comes from Epic Games' Mark Rein, who told Eurogamer earlier this summer that 'over half the users who played Gears of War 2 so far do not have HDTVs.' Gears of War is a core gamer franchise, beloved of early adopters and the [so-called] hardcore. If less than half of those users are playing on HDTVs, what must the percentages be like for games like FIFA and Pro Evolution Soccer — let alone Singstar and Buzz, or popular movie tie-in titles?"

stoolpigeon writes "Scientists on Florida's Gulf Coast are trying to find an underwater robot that has mysteriously vanished. The robot from the Mote Marine Laboratory in Sarasota has been missing since Monday. The robot, which cost about $100,000, was equipped with a detector to find red tide, a toxic algae bloom. The detector was valued at another $30,000. Scientists aren't sure what happened to the robot, which is nicknamed Waldo."

Al writes "It might not please many environmentalists, but a major energy company is adding solar-thermal power to a coal plant and says this could be the cost-effective way to produce energy while lowering CO2 emissions. Abengoa Solar and Xcel Energy, Colorado's largest electrical utility, have begun modifying the coal plant, which is based near Grand Junction, Colorado. Under the design, parabolic troughs will be used to preheat water that will be fed into the coal plant's boilers, where coal is burned to turn the water into steam. Cost savings comes from using existing turbines and generators and from operating at higher efficiencies, since the turbines and generators in solar-thermal plants are normally optimized to run at the lower temperatures generated by parabolic mirrors."

Lucas123 writes "Intel is planning to launch its native flash memory module, code named Braidwood, in the first or second quarter of 2010. The inexpensive NAND flash will reside directly on a computer's motherboard as cache for all I/O and it will offer performance increases and other benefits similar to that of adding a solid-state disk drive to the system. A new report states that by achieving SSD performance without the high cost, Braidwood will essentially erode the SSD market, which, ironically, includes Intel's two popular SSD models. 'Intel has got a very good [SSD] product. But, they view additional layers of NAND technology in PCs as inevitable. They don't think SSDs are likely to take over 100% of the PC market, but they do think Braidwood could find itself in 100% of PCs,' the report's author said."

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.'"
