Oregon Senator Stops Internet Censorship Bill 315

comforteagle writes "Senator Wyden of Oregon has objected to a bill in committee that if passed would have given the government the ability to censor the Internet. His objection effectively stop its current passing, forcing it to be introduced again if the bill is to continue — which it may not. Oregonians, please send this man pats on the back."

British Gov't Releases Spending Data 89

An anonymous reader writes "In a move sure to have transparency activists salivating, the UK government has released some 195,000 lines of data detailing its financial outgoings. The BBC reports that 'All spending of more than £25,000 made between May and September was published — in line with a pre-election commitment by the Conservatives — although some departments also published spending over £500. People are being encouraged to pick through the enormous quantity of online information to spot waste and hold ministers to account.'"

Traffic Jams In Your Brain 250

An anonymous reader writes "Carl Zimmer's latest foray into neuroscience examines why the brain can get jammed up by a simple math problem: 'Its trillions of connections let it carry out all sorts of sophisticated computations in very little time. You can scan a crowded lobby and pick out a familiar face in a fraction of a second, a task that pushes even today's best computers to their limit. Yet multiplying 357 by 289, a task that demands a puny amount of processing, leaves most of us struggling.' Some scientists think mental tasks can get stuck in bottlenecks because everything has to go through a certain neural network they call 'the router.'"

Arduino-Based, High Powered LED Lighting Over Wi-Fi 114

Gibbs-Duhem writes "This awesome video was produced by some MIT engineers recently. They've started a fully open-source, open-hardware high power LED lighting project that they designed to be modular enough to control with the Arduino (or any other control system). Using their open-source firmware, you can set up the Arduino to connect to Wi-Fi and receive Open Sound Control packets. Then, they went further and released open-source software for PureData and Python to do music analysis and make the lights flash brilliantly in time with the music! A full Instructable was also posted in addition to the existing documentation for design and assembly on their website."

Submission + - 25 Years of Windows: From Interface Manager to 7 (computerworld.com)

CWmike writes: Twenty-five years ago, on Nov. 20, 1985, Microsoft introduced its first version of Windows to the world, writes Preston Gralla. Not many people outside the technical press or the tech industry took notice. Product launch events that cost hundreds of millions of dollars were still years away. What's changed in Windows in the last 25 years? Plenty. In this visual tour, we take a look at the various faces of Windows over the past couple of decades and clue you in to what happened at every stage of the operating system's development.

Life Found In Deepest Layer of Earth's Crust 335

michaelmarshall writes "For the first time, life has been found in the gabbroic layer of the crust. The new biosphere is all bacteria, as you might expect, but they are different from the bacteria in the layers above; they mostly feed on hydrocarbons that are produced by abiotic reactions deep in the crust. It could mean that similar microbes are living even deeper, perhaps even in the mantle."

The Problem With the Top500 Supercomputer List 175

angry tapir writes "The Top500 list of supercomputers is dutifully watched by high-performance computing participants and observers, even as they vocally doubt its fidelity to excellence. Many question the use of a single metric — Linpack — to rank the performance of something as mind-bogglingly complex as a supercomputer. During a panel at the SC2010 conference this week in New Orleans, one high-performance-computing vendor executive joked about stringing together 100,000 Android smartphones to get the largest Linpack number, thereby revealing the 'stupidity' of Linpack. While grumbling about Linpack is nothing new, the discontent was pronounced this year as more systems, such as the Tianhe-1A, used GPUs to boost Linpack ratings, in effect gaming the Top500 list." Fortunately, Sandia National Laboratories is heading an effort to develop a new set of benchmarks. In other supercomputer news, it turns out the Windows-based cluster that lost out to Linux stumbled because of a bug in Microsoft's software package. Several readers have also pointed out that IBM's Blue Gene/Q has taken the top spot in the Green500 for energy efficient supercomputing, while a team of students built the third-place system.

Submission + - Whitehat Hacker's Laptop, Cellphones Seized (net-security.org)

Orome1 writes: The well-known whitehat hacker and security researcher that goes by the handle Moxie Marlinspike has recently experienced firsthand the electronical device search that travelers are sometimes submitted to by border agents when entering the country. He was returning from the Dominican Republic by plane, and when he landed at JFK airport, he was greeted by two U.S. Customs officials and taken to a detention room where they kept him for almost five hours, took his laptop and two cell phones and asked for the passwords needed to access the encrypted material on them.

Submission + - Chess Terminator Robot Takes on Former World Champ (gizmag.com)

Zothecula writes: For almost as long as we've had computers, humans have been trying to make ones that play chess. The most famous chess-playing computer of course is IBM's Deep Blue, which in 1997 defeated the then World Champion Garry Kasparov. But as powerful as Deep Blue was, it didn't actually move the chess pieces on its own. Perhaps that's a trivial task in comparison to beating the best chess player of all-time, but it's still exciting to discover this recent video of a chess robot that more closely fits the true definition of a chess automaton.
Education

200 Students Admit Cheating After Professor's Online Rant 693

Over 200 University of Central Florida students admitted to cheating on a midterm exam after their professor figured out at least a third of his class had cheated. In a lecture posted on YouTube, Professor Richard Quinn told the students that he had done a statistical analysis of the grades and was using other methods to identify the cheats, but instead of turning the list over to the university authorities he offered the following deal: "I don't want to have to explain to your parents why you didn't graduate, so I went to the Dean and I made a deal. The deal is you can either wait it out and hope that we don't identify you, or you can identify yourself to your lab instructor and you can complete the rest of the course and the grade you get in the course is the grade you earned in the course."

LHC Scientists Create and Capture Antimatter 269

Velcroman1 writes "Scientists at the Large Hadron Collider have created antimatter in the form of antihydrogen, demonstrating how it's possible to capture and release it. The development could help researchers devise laboratory experiments to learn more about this strange substance, which mostly disappeared from the universe shortly after the Big Bang 14 billion years ago. Trapping any form of antimatter is difficult, because as soon as it meets normal matter — the stuff Earth and everything on it is made out of — the two annihilate each other in powerful explosions. 'We are getting close to the point at which we can do some classes of experiments on the properties of antihydrogen,' said Joel Fajans, a University of California, Berkeley professor of physics, and LBNL faculty scientist. 'Since no one has been able to make these types of measurements on antimatter atoms at all, it's a good start.'"
