cyclocommuter writes with an excerpt from a brief WSJ story on increasing electronic control of car components: "The gas pedal system used Toyota Motor Co.'s recall crisis was born from a movement in the auto industry to rely more on electronics to carry out a vehicle's most critical functions. The intricacy of such systems, which replace hoses and hydraulic fluid with computer chips and electrical sensors, has been a focus as Toyota struggled to find the cause for sudden acceleration of vehicles that led the company to halt sales of eight models this week."

diegocg writes "Linus Torvalds has officially released the version 2.6.32 of the Linux kernel. New features include virtualization memory de-duplication, a rewrite of the writeback code faster and more scalable, many important Btrfs improvements and speedups, ATI R600/R700 3D and KMS support and other graphic improvements, a CFQ low latency mode, tracing improvements including a 'perf timechart' tool that tries to be a better bootchart, soft limits in the memory controller, support for the S+Core architecture, support for Intel Moorestown and its new firmware interface, run-time power management support, and many other improvements and new drivers. See the full changelog for more details."

theodp writes "At MIT, an experiment that identifies which students are gay is raising new questions about online privacy. Using data from Facebook, two students in an MIT class on ethics and law on the electronic frontier made a striking discovery: just by looking at a person's online friends, they could predict whether the person was gay. The project, given the name 'Gaydar' by the students, is part of the fast-moving field of social network analysis, which examines what the connections between people can tell us, from predicting who might be a terrorist to the likelihood a person is happy, fat, liberal, or conservative." MIT professor Hal Abelson, who co-taught the course, is quoted: "That pulls the rug out from a whole policy and technology perspective that the point is to give you control over your information — because you don't have control over your information."

Frequent Slashdot contributor Bennett Haselton writes " Amid the latest 'sexting' controversy, here is a proposal for a scientifically objective method to determine whether a picture constitutes child pornography. This is a harder problem than it seems, but not for the reasons you'd think. And it raises questions about how the same scientific principles could be applied to other matters of law."

Eurogamer reports that Sony Online Entertainment will be adding the ability to do real money trading to at least some of their Vanguard: Saga of Heroes servers. It's the same service they opened for a pair of Everquest II servers a while back. Quoting: "The service, offered by Live Gamer, allows players to sell items, currency and characters for real cash through a secure channel, authorised by the game operator. Most real-money trading in MMOs is a 'grey' market that doesn't have the operator's consent. ... Sony Online Entertainment recently said that it had no intention to bring its other real-money trading initiative — the Station Cash item shop — to Vanguard."

Technology Review has a writeup on the latest advance in the lab towards an invisibility cloak made of metamaterials, described this week in Science. We've been following this technology since the beginning. The breakthrough is software that lets researchers design materials that are both low-loss and wideband. "The cloak that the researchers built works with wavelengths of light ranging from about 1 to 18 gigahertz — a swath as broad as the visible spectrum. No one has yet made a cloaking device that works in the visible spectrum, and those metamaterials that have been fabricated tend to work only with narrow bands of light. But a cloak that made an object invisible to light of only one color would not be of much use. Similarly, a cloaking device can't afford to be lossy: if it lets just a little bit of light reflect off the object it's supposed to cloak, it's no longer effective. The cloak that Smith built is very low loss, successfully rerouting almost all the light that hits it."

zootropole writes "If you are using Firefox 3 (or even Chrome) you should consider taking a look at Mozilla's Minefield. This browser (alpha version yet, but stable) would give a new meaning to 'fast browsing experience.' Some Firefox extensions aren't supported, but riding the fastest javascript engine on the planet definitely worth a try. Minefield's install won't affect your Firefox, so there's no risk trying it. It's fast. Really. And I'm loving it." Reviews popping up around the web are overwhelmingly positive, calling the upcoming browser crazy fast, blisteringly fast, etc.
