Submission + - Gravity explained as not a force. (google.nl)

sciencewatcher writes: The Dutch theoretical physicist Erik Verlinde proposed a remarkable simple theory which explains gravity as a statistical phenomenon resulting from different concentrations of information in empty spaces between masses. If it holds the magnitude of this new theory is of the same order as Einstein's introduction of the relativity theory and would result in a rewrite of all secondary education physics books. 'Gravity is not a fundamental force. It emergences from a deeper microscopic reality' he stated in a newspaper article (Dutch, Google translated). Simple Newtonian laws like the law of motion (F=m*a) can be easily derived from the new theory. So far his colleagues have stated to be intrigued rather than sceptic. The implications for other theories such as the unification theory are enormous.

Submission + - e-readers get flexible screens (arnnet.com.au)

nadiskafadi writes: Taiwanese researchers have shown off several flexible display technologies in an endeavour to promote e-readers and e-paper. One of the newest technologies from Industrial Technology Research Institute (ITRI) was a flexible 4.1-inch color OLED (organic light emitting diode) display, which it claims is for the next era of portable devices.

Comment Cygwin or UWIN (Score 4, Interesting) 310

If you want "close to the metal" POSIX API compatibility then there's Cygwin which is easier to use IMO and more actively developed but doesn't support the *full* POSIX spec or there is UWIN which supports most of the POSIX spec.

Combine this with OpenGL, OpenAL, the SDL and Cygwin/X, QT, a Java layer using the SWT from Eclipse, *shudder* GLUT *shudder* ;) or IMNSHO preferably wxWindows/wxWidgets and you've got yourself a full cross-platform programming toolkit that can do just about anything.

Comment Eurosoft PC Check (Score 4, Informative) 274

This is probably one of the best and most comprehensive OS agnostic boot-CD/floppy general purpose PC hardware testing and burn-in tools I've come across IMHO.

Here's its web page : http://www.eurosoft-uk.com/pc_check.htm

In any case, I recommend plugging the ATX cable into a power supply tester that presents a non-trivial load as a first step in diagnosing any PC. You'd be surprised in what ways the problems caused by out-of-spec voltages can be manifested.

Submission + - Aid agencies turn to open-source software (newscientist.com)

holy_calamity writes: "Computer science students across the US are being encouraged to chip in to a new kind of open source project — one aimed at making software for charities to use when dealing with humanitarian disasters. HFOSS, for Humanitarian Free and Open Source Software, recently tested its flagship tool Collabitt with charities including the Salvation Army in a "war game" that simulated a hurricane hitting a large US city. The Salvation Army report that using open source works for them because in this niche market it would be too costly to direct development of features with a commercial vendor as they can with an HFOSS project."

Submission + - Researchers Hijack Botnet, Watch Driveby Downloads (technologyreview.com)

TechReviewAl writes: Researchers at the University of California at Santa Barbara hijacked the Mebroot botnet for about a month and used it to study drive-by downloading. The researchers managed to intercept Mebroot communications by reverse-engineering the algorithm used to select domains to connect to. Mebroot infects legitimate websites and uses them to redirect users to malicious sites that attempt to install malware on a victim's machine. The team, who previously infiltrated the Torpig botnet, found that at least 13.3 percent of systems that were redirected by Mebroot were already infected and 70 percent were vulnerable to about 40 common attacks.

Submission + - Mercedes Prototype Automatically Brakes at Redligh (gizmodo.com)

suraj.sun writes: Mercedes-Benz is experimenting with the smart intersection technology that stops the car at redlight if driver doesn't notice or doesn't care, at their R&D facility in Palo Alto, California.

Using a smart intersection, the light essentially communicates with the car. And if the driver still isn't responsive to, say, brake after several warnings of a red light, the car can stop itself.

Mercedes-Benz admits that, though the technology is "almost there," we're still a decade out from its deployment. When implemented, it won't just be about safety: cars that include the wireless transceivers can conduct a "conversation" with one other to share realtime local traffic data, as well as to warn the driver if he or she is accelerating into a stop light.

Submission + - Is Cloud Computing the Hotel California of Tech? (cnet.com)

ScuttleMonkey writes: "Prolific blogger and open source enthusiast Matt Asay ponders whether cloud computing may be the Hotel California of tech. It seems that data repositories in the form of Googles and Facebooks are very easy to dump data into, but can be quite difficult to move data between. "I say this because even for companies, like Google, that articulate open-data policies, the cloud is still largely a one-way road into Web services, with closed data networks making it difficult to impossible to move data into competing services. Ever tried getting your Facebook data into, say, MySpace? Good luck with that. Social networks aren't very social with one other, as recently noted on the Atonomo.us mailing list. For the freedom-inclined among us, this is cause for concern. For the capitalists, it's just like Software 1.0 all over again, with fat profits waiting to be had. The great irony, of course, is that it's all built with open source.""

An anonymous reader writes: The Federal Trade Commission will require bloggers to clearly disclose any freebies or payments they get from companies for reviewing their products.

It is the first time since 1980 that the commission has revised its guidelines on endorsements and testimonials, and the first time the rules have covered bloggers.

Submission + - G20 Protesters Arrested for Using Twitter (pittsburghlive.com) 1

xappax writes: Two hackers set up a real-time "information clearinghouse" system during the recent protests of the G20 summit in Pittsburgh. The system used custom software combined with Twitter to allow them to receive and send instant updates on what was happening during the protests, such as food servings, changes in schedule, and police activity on the streets.
They have both been arrested for "criminal use of a communication facility", and one had his home in Queens raided by FBI anti-terrorism agents.
Is using Twitter to aggregate publicly available information a crime?

MikeChino writes: As the United States government continues to drag its heels on passing climate change legislation, itâ(TM)s encouraging to see folks in Europe making moves in the right direction. Last week, the French government announced it would dedicate $2.2 billion to creating a network of battery-charging stations for electric vehicles. The plan will also require all parking lots to contain battery charging stations by 2015, paving the way for a massive shift towards cleaner transportation.

Submission + - Mesh Multiprotocol with Madwifi, OLSR and Debian (libelium.com)

lannicor writes: Among the bunch of different "Linux based" routers in the market, there is a special family known as mesh routers. These routers implement adhoc connections in order to create multipath and dynamic wireless networks. Big companies in the wireless market as Cisco and Motorola already have their own proprietary mesh protocol solutions, which are used to create muni-wireless networks to give connectivity to cities. The term multiprotocol is applied to those routers which integrate different wireless radios: Wifi (802.11), ZigBee (802.15.4), Bluetooth (802.15.1)... so that information from one interface can be switched to the others in the same device. The open source mesh algorithm OLSR has been chosen along with the Madwifi drivers and Voyage (a Debian based embedded distro) to be part of a new mesh multiprotocol router platform called Meshlium . The project counts also with an Ajax-PHP web application — Mesh Manager — to control the system and the radio interfaces. The project seems to be "developers oriented" as it is based in a plugin-architecture. Although the Mesh Manager has been developed to work in a embedded system, the project site points out it can be tested in any Linux environment (the code is also available).
