Al writes "European researchers have taken a step towards replicating the functioning of the brain in silicon, creating new custom chip with the equivalent of 200,000 neurons linked up by 50 million synaptic connections. The aim of the Fast Analog Computing with Emergent Transient States (FACETS) project is to better understand how to construct massively parallel computer systems modeled on a biological brain. Unlike IBM's Blue Brain project, which involves modeling a brain in software, this approach makes it much easier to create a truly parallel computing system. The set-up also features a distributed algorithm that introduces an element of plasticity, allowing the circuit to learn and adapt. The researchers plan to connect thousands of chips to create a circuit with a billion neurons and 10^13 synapses (about a tenth of the complexity of the human brain)."

microbee writes "Following the Linux kernel 2.6.29 release, several famous kernel hackers have raised complaints upon what seems to be a long-time performance problem related to ext3. Alan Cox, Ingo Molnar, Andrew Morton, Andi Keen, Theodore Ts'o, and of course Linus Torvalds have all participated. It may shed some light on the status of Linux filesystems. For example, Linus Torvalds commented on the corruption caused by writeback mode, calling it 'idiotic.'"

BountyX writes "First and foremost, wikileaks.org is back up after downtime due to server load; however, the German government wants to keep the site down. According to their twitter page, police have raided the home of Wikileaks.de domain owner Theodor Reppe (PDF) over internet censorship lists that were leaked two weeks ago. What the Australian government's secret ACMA internet censorship blacklist has to do with Germany is a mystery. This case is a prime example of multiple governments collaborating in support of censorship." Reader iter8 provides a link to coverage on Wikileaks itself, which says that police searched Reppe's homes in both Dresden and Jena, and adds: "According to police, the reason for the search was 'distribution of pornographic material' and 'discovery of evidence.' Wikileaks has published censorship lists for Australia, Thailand, Denmark and other countries. Included on the lists are references to sites alleged to contain pornography, including child pornography. Wikileaks has not published any images from the sites."

Chickan writes "'A puff a day might keep Alzheimer's away, according to marijuana research by professor Gary Wenk and associate professor Yannic Marchalant of the Ohio State Department of Psychology. Wenk's studies show that a low dosage in the morning of a certain canavanoid, a component in marijuana, reversed memory loss in older rats' brains. In his study, an experimental group of old rats received a dosage, and a control group of rats did not. The old rats that received the drugs performed better on memory tests, and the drug slowed and prevented brain cell death.' My fine university's dollars at work!" Maybe it works even better in combination with brain-preserving sips of coffee.

mytrip writes "In what may come to be seen as a deeply symbolic moment in the history of operating systems, Red Hat is on the verge of surpassing Sun Microsystems' market capitalization for the first time. Sun, perhaps unfairly, represents a fading Unix market. Red Hat, for its part, represents the rising Linux market. Given enough time for its open-source strategy to play out, Sun's market capitalization will likely recover and outpace Red Hat's."

snydeq writes "Windows XP, Windows Vista, and (soon) Windows 7 all support SMP out of the box, but as InfoWorld's Randall Kennedy notes, 'experience has shown that multiprocessing across discrete CPUs is not the same thing as multiprocessing across integrated cores within the same CPU.' As such, Kennedy set out to stress the multiprocessing capabilities of Windows XP, Windows Vista, and Windows 7 in dual-core and quad-core performance tests. The comprehensive, multiprocess workload tests were undertaken to document scalability, execution efficiency, and raw performance of workloads. 'What I found may surprise you,' Kennedy writes. 'Not only does Microsoft have a firm grasp of multicore tuning, but its scalability story promises to keep getting better with time. In other words, Windows Vista and Windows 7 are poised to reap ever greater performance benefits as Intel and AMD extend the number of cores in future editions of their processors.'"

Ian Lamont writes "The Electronic Frontier Foundation and the National Security Archive are praising President Obama's executive orders to make the federal government more open. Yesterday, Obama issued two memos and one executive order instructing government agencies to err on the side of making information public and not to look for reasons to legally withhold it. The moves are expected to make it easier for people to file Freedom of Information Act requests, and should also boost the amount of information that agencies place on their websites. The general counsel for the National Security Archive (an NGO that publishes declassified documents obtained through the Freedom of Information Act) even predicts that agencies will use blogs to share information. Obama's directives reverse a 2001 memo from former US Attorney General John Ashcroft instructing federal agencies to generally withhold information from citizens filing FOIA requests."

Smivs writes "The BBC are reporting on the development of tiny motors the size of a grain of salt which could power surgical Microbots. Some surgical procedures are hindered by the size or inflexibility of current instruments. For example, the labyrinthine network of blood vessels in the brain prevents the use of catheters threaded through larger blood vessels. Researchers have long envisioned that trends of miniaturisation would lead to tiny robots that could get around easily in the body. The problem until now has been powering them. Conventional electric motors do not perform as well as they are scaled down in size. As they approach millimetre dimensions, they barely have the power to overcome the resistance in their bearings. Now, research reported in the Journal of Micromechanics and Microengineering has demonstrated a motor about 1/4mm wide, about the width of two human hairs."

GamePolitics writes "A researcher at Texas A&M International University has found no link between playing violent video games and school shootings. Prof. Christopher Ferguson cites 'moral panic' and criticizes politicians, the news media and some social scientists for playing up what he believes is a false connection between video games and school shooting incidents. Quoting: 'Actual causes of violent crime, such as family environment, genetics, poverty, and inequality, are oftentimes difficult, controversial, and intractable problems. By contrast, video games present something of a "straw man" by which politicians can create an appearance of taking action against crime.'"

coondoggie writes "Researchers say technology they have developed would let boats or small aquatic robots glide through the water without the need for an engine, sails or paddles. A University of Pittsburgh research team has designed a propulsion system that uses the natural surface tension that is present on the water's surface and an electric pulse to move the boat or robot, researchers said. The Pitt system has no moving parts and the low-energy electrode that emits the pulse could be powered by batteries, radio waves, or solar power, researchers said in a statement."
