sl4shd0rk writes "Mozilla and Epic (of Epic Megagames fame) have engineered an impressive First Person OpenGL demo which runs on HTML5 and a subset of JavaScript. Emscripten, the tool used, converts C and C++ code into 'low level' JavaScript. According to Epic, The Citadel demo runs 'within 2x of native speeds' and supports features commonly found in native OpenGL games such as dynamic specular lighting and global illumination. This concept was previously covered on Slashdot, however the Citadel demo has just been released this week."

sciencehabit writes "The Boston marathon bombers Tamerlan and Dzhokhar Tsarnaev reportedly purchased several pounds of black powder explosive before the bombing. Used in fireworks and bullets, the explosive substance is both deadly and widely available. It's also very hard to detect. Now, researchers have modified one bomb-sniffing device to accurately spot very small amounts of black powder, an advance that could make us safer from future attacks. What has prevented detection of black powder by IMS in the past, however, is that sulfur and oxygen -- which composes 20% of air—hit the detector at almost the same time. A strong oxygen signal can thus mask a small amount of sulfur, like what a bombmaker's dirty fingers might leave on a luggage strap. A group led by chemist Haiyang Li at the Dalian Institute of Chemical Physics in China modified an IMS to eliminate the oxygen signal. 'We have tested the sensitivity of TR-IMS, and its limit of detection of black powder can reach as low as 0.05 nanograms,' Li says."

Portugals premiärminister Pedro Passos Coelho föreslår att 30 000 jobb i den offentliga sektorn ska försvinna som en del av ekonomiska reformpaket.

De flesta människor har några markörer som kan tyda på våldsbenägenhet. De kopplas till störningar under tredje och fjärde månaden av graviditeten och kan sammanfalla med neurologiska störningar i hjärnan som ger ökad våldsbenägenhet. Om man inte har många samtidigt saknar de helt betydelse. Exempel på andra markörer: Åtsmitande öron, elektrostatiskt hår och små böjda fingrar.

Nerval's Lobster writes "The 'Sequoia' Blue Gene/Q supercomputer at the Lawrence Livermore National Laboratory (LLNL) has topped a new HPC record, helped along by a new 'Time Warp' protocol and benchmark that detects parallelism and automatically improves performance as the system scales out to more cores. Scientists at the Rensselaer Polytechnic Institute and LLNL said Sequoia topped 504 billion events per second, breaking the previous record of 12.2 billion events per second set in 2009. The scientists believe that such performance enables them to reach so-called "planetary"-scale calculations, enough to factor in all 7 billion people in the world, or the billions of hosts found on the Internet. 'We are reaching an interesting transition point where our simulation capability is limited more by our ability to develop, maintain, and validate models of complex systems than by our ability to execute them in a timely manner,' Chris Carothers, director of the Computational Center for Nanotechnology Innovations at RPI, wrote in a statement."

ErichTheRed writes "Here's yet another example of why it's very important to make sure IT employees' access is terminated when they are. According to the NYTimes article, a former employee of this company allegedly accessed the ERP system after he was terminated and had a little 'fun.' 'Employees at Spellman began reporting that they were unable to process routine transactions and were receiving error messages. An applicant for his old position received an e-mail from an anonymous address, warning him, “Don’t accept any position.” And the company’s business calendar was changed by a month, throwing production and finance operations into disorder.' As an IT professional myself, I can't ever see a situation that would warrant something like this. Unfortunately for all of us, some people continue to give us a really bad reputation in the executive suite."
