Vigile writes "Performance analysis on solid state drives is still coming into clarity as more manufacturers enter the fold and more of the drives find their way into users' hands. While Intel's dominance in the SSD market was once undoubted, newer garbage collection methods from Indilinx and Samsung are now balancing performance across the the major players. What hasn't been discussed in great detail yet is the effect that drive capacity can have on overall performance. Some smaller drives (64GB versus 128GB) will actually use fewer data channels from the controller chip and thus will have lower transfer speeds. The article compares drives using controllers from Indilinx, Samsung and Intel." Note that PCPer greedily spans this review over 12 pages. Next time maybe they can keep it down to something more reasonable.

theodp writes "A Bloomberg report that Apple CEO Steve Jobs proposed a possibly illegal truce with Palm against poaching their respective employees is sure to pique the interest of the US Department of Justice, which already is investigating whether Google, Yahoo, Apple, Genentech and other tech companies conspired to keep others from stealing their top talent. 'Your proposal that we agree that neither company will hire the other's employees, regardless of the individual's desires, is not only wrong, it is likely illegal,' former Palm CEO Ed Colligan reportedly told Jobs in August 2007." The article notes that Apple was probably reacting to Palm's hiring of Jon Rubenstein, who had been instrumental in developing the iPod and went on to spearhead the Pre for Palm (and has now become Palm's chairman and CEO). "It's the story about the importance of charismatic engineers," said veteran Silicon Valley forecaster Paul Saffo. "People don't work for Palm. They work for Jon Rubinstein. One has to wonder how Steve Jobs ever let Jon Rubinstein leave."

BobB-nw writes "A group of engineering students and their professor at National Taiwan University have built a robot that can map out the area it's operating in and offer guided tours. The robot, named 'Hsiao Mei,' uses laser mapping and GPS technology to navigate on its own, including around corners and obstacles such as tables and chairs. In the first public demonstration on Thursday, an engineering student with a wireless remote control first took the robot through the floor of a small museum on the university's campus so it could create a map for itself. After the initial run-through, the robot was able to make an unaided journey around the floor."

inkslinger77 writes "Computerworld has a cool slideshow of a Kuka Titan robot and a bunch of AGVs managing the circulation of coins at the Australian Mint. There's also a lengthier article where the head of the project talks about the main reason robots were employed. One of the reasons being that they radically reduce OH&S risk: 'We are finding that the AGVs are much safer and more reliable. Robots are never affected by having a bad night with the baby and falling asleep at the wheel. They are extremely accurate and they always do the same task in the same way.'"

ericatcw writes "Apple Inc. may still be coy about whether it plans to launch a touch-screen tablet computer this year, but Windows PC makers are forging right ahead. In the past three weeks, five leading PC makers have announced or been reported to confirm plans to release touch-screen PCs in time for the multi-touch-enabled Windows 7, reports Computerworld. Many appear to be using technology from New Zealand optical touch vendor, NextWindow, which already supplies HP's market-leading TouchSmart line, and Dell's Studio One. NextWindow's CEO says the company is working with partners on 8-10 products set for launch within two months, in time for Windows 7's October 22nd release."

Trio writes "What will cellphones look like in in future? silicon.com explores five future characteristics that could shape tomorrow's phones — from a wearable prototype such as MIT's SixthSense device which projects mobile data into the user's world, to a mobile that mixes the real and the virtual by using holographic telepresence. So far, so futuristic, but one question remains: will there be enough spectrum to support all this wireless communication?"

lee1 writes "The first-ever video advertisement will be published in a traditional paper magazine — Entertainment Weekly — in September. The video will be displayed on slim-line screens around the size of a mobile phone display and will have rechargeable batteries. The associated chip can hold up to 40 minutes of video, and uses technology similar to that used in singing greeting cards, playing the movie when the page is turned. The first clips will preview CBS shows and advertise Pepsi, but they will only be distributed in Los Angeles and New York. Imagine the fun hacking possibilities."

Professor_Quail writes "PC Magazine reports that the PCI SIG has officially delayed the release of the PCI Express 3.0 specification until the second quarter of 2010. Originally, the PCI Express 3.0 specification called for the spec itself to be released this year, with products due about a year after the spec's release, or in 2010."

Hugh Pickens writes "New Scientist reports that, faced with global warming and potential oil shortages, the US Navy is experimenting with making jet fuel from seawater by processing seawater into unsaturated short-chain hydrocarbons that with further refining could be made into kerosene-based jet fuel. The process involves extracting carbon dioxide dissolved in the water and combining it with hydrogen — obtained by splitting water molecules using electricity — to make a hydrocarbon fuel, a variant of a chemical reaction called the Fischer-Tropsch process, which is used commercially to produce a gasoline-like hydrocarbon fuel from syngas, a mixture of carbon monoxide and hydrogen often derived from coal. The Navy team have been experimenting to find out how to steer the CO2-producing process away from producing unwanted methane by finding a different catalyst than the usual one based on cobalt. 'The idea of using CO2 as a carbon source is appealing,' says Philip Jessop, a chemist at Queen's University adding that to make a jet fuel that is properly 'green,' the energy-intensive electrolysis that produces the hydrogen will need to use a carbon-neutral energy source; and the complex multi-step process will always consume significantly more energy than the fuel it produces could yield. 'It's a lot more complicated than it at first looks.'"

coondoggie writes "The US Marine Corps has a request — build and rapidly deploy more 10lb-or-under robots its personnel can throw into dangerous situations that can quickly gather information without endangering Marines. The throwable robot is part of a family of robots that would range from the 10lb version to one that would act as a central controlling device and weigh close to 300lbs. Marine commanders are demanding ever lighter robots so that troops don't have to offload critical equipment from their rucksacks to accommodate them."

An anonymous reader writes "A group of hardware hackers has created a motherboard prototype that uses separate modules, each of which has its own processor, memory and storage. Each square cell in this design serves as a mini-motherboard and network node; the cells can allocate power and decide to accept or reject incoming transmissions and programs independently. Together, they form a networked cluster with significantly greater power than the individual modules. The design, called the Illuminato X Machina, is vastly different from the separate processor, memory and storage components that govern computers today."

Al writes "Researchers at Microsoft and the University of California, San Diego have developed a network adapter that lets a computer enter sleep mode without disrupting the network connection. The adapter, dubbed Somniloquy (meaning to talk in one's sleep), consists of a gumstix running embedded Linux, 64MB of RAM and a 2G SD memory card, connected via USB. The adapter keeps the network connection going and the researchers have also developed a simplified IM client and bittorrent client that carry out more complicated tasks autonomously, only waking the computer if, for example, an actualy IM is received or a download is completed."

pdragon04 writes "Researchers at the Ecole Polytechnique Fédérale de Lausanne in Switzerland have found that robots equipped with artificial neural networks and programmed to find 'food' eventually learned to conceal their visual signals from other robots to keep the food for themselves. The results are detailed in a PNAS study published today."

stadium writes "An oil-filled transformer exploded at the Sayano-Shushenskaya power plant in Siberia, destroying three turbines and bringing down the ceiling of the turbine hall, which then violently flooded. The dam itself did not sustain any damage. It is unclear how many people were killed, but with 12 confirmed deaths and as many as 64 still missing (all presumed dead), this is a serious incident. The huge transformer had enough oil in it to produce a three-mile-long oil spill slowly moving downriver. BBC News reports with three separate videos. The dam produces a quarter of the total energy of RusHydro (whose stock thus took a steep dive at London Stock Exchange) and also feeds the world's largest aluminum smelter. The damages will take years to repair."

Jake Staub writes "Just replaced the gasoline engine in a Honda Insight with a Diesel engine. On a 3,000 mile cross-country shakedown journey the car averaged 92mpg over 1,800 miles. Around a very hilly town in Northwest Washington, the car is averaging 78mpg. These mileage averages are without the electric side of the vehicle fully functional. With a bit more tinkering on the electric side and through a slight gearing change through tire size, it is anticipated that the car will likely average 100mpg. The build for the car has been documented on the web site and is as close to open source as my time allows. The car was built by two guys in a garage in Southern Maryland. If we can do it I don't see any reason why major auto manufacturers can't do it since we used their parts."

snydeq writes "Scientists at IBM are experimenting with using DNA molecules as a way to create tiny circuits that could form the basis of smaller, more powerful computer chips. The technique builds on work done by Cal Tech's Paul Rothemund, who found that DNA molecules can be made to 'self-assemble' into tiny forms [PDF] such as triangles, squares and stars. 'To make a chip, the scientists first create lithographic templates using traditional chip making techniques. After, they pour a DNA solution over the surface of the silicon and the tiny triangles and squares — what the scientists call DNA origami — line themselves up to the patterns etched out using lithography.' DNA-based chips may sound like crackpot tech, but those involved believe the methodology could lead to a new way of fabricating features on the surface of chips that allows semiconductors to be made even smaller, faster and more power-efficient than they are today."

Many sources are reporting that researchers have created the world's smallest laser since the inception of lasers almost a half-century ago. Dubbed "spasers," as an acronym for "surface plasmon amplification by stimulated emission of radiation," their incredibly tiny size could become a critical component for future technologies like "nanophotonic" circuitry. "Such circuits will require a laser-light source, but current lasers can't be made small enough to integrate them into electronic chips. Now researchers have overcome this obstacle, harnessing clouds of electrons called 'surface plasmons,' instead of the photons that make up light, to create the tiny spasers."

Al writes "NASA recently finished testing a miniature nuclear reactor that would provide power for an astronaut base on the Moon or Mars. The reactor combines a small fission system with a Stirling engine to make a 'safe, reliable, and efficient' way to produce electricity. The system being tested at NASA's Glenn Research Center can produce 2.3 kilowatts and could be ready for launch by 2020, NASA officials say. The reactor ought to provide much more power than solar panels but could prove controversial with the public concerned about launching a nuclear power source and placing it on the Moon or another planet."

Al writes "Researchers from MIT, Carnegie Mellon and Akamai have developed a network-routing scheme that could save 'internet-scale' companies such as Google, Amazon and Microsoft million of dollars each year by moving data to locations with the best electricity prices for a particular day. The scheme simply considers both the most efficient routing path for data and the potential cost savings of routing it somewhere farther away. The researchers studied price fluctuations at locations across the country and used data from Akamai caching servers to test the idea out. In the best possible scenario — which would require more efficient servers — they estimate that companies could save as much as 40% on the electricity bills (tens of millions each year). Google already operates at least one datacenter that shuts down when temperatures get too high. Is this the next logical step for internet computing?"

An anonymous reader writes "Four days ago, deputies from the Maricopa County Sheriff's Office in Arizona conducted a raid against the county government building hosting computers for a law enforcement database. After threatening to arrest county employees who would stop them, the officers proceeded to secure the room and promptly changed passwords on many of the servers. In a hearing on Friday, a Superior Court judge threatened to hold members of the Sheriff's Office in contempt if they did not reveal the passwords by next Wednesday. Following this, the Sheriff's Office claimed to be conducting an investigation against other Superior Court judges. Courts have asked for passwords before, but never under conditions like this."
