Texas man foretells dire outcome: messages 'I need to quit texting,'
Sent to you by diluted via Google Reader:
Despite our love of gadgets, we're not willing to give any slack to people that text while driving, and for one good reason: it's freaking dangerous. You've heard the grim stories before, but few incidents resonate to the heart of the matter like that of Chance Bothe from Texas. Despite his better judgment, the young man was texting a childhood friend while trying to bring the conversation to a close by saying, "I need to quit texting, because I could die in a car accident." That message was followed by one more, an unfortunate, "b right there." Regrettably, that final text caused him to miss a slight curve in the road and careen into a ravine. Chance is alive today -- thanks in large part to the fact that the accident was witnessed -- but the recovery hasn't been easy. In addition to a broken neck, a number of fractures and severe head trauma, he's already undergone two facial reconstructions. In the wake of the accident, Chance's friends and family have founded UnSend, an organization that dedicates itself to raising awareness about the dangers of texting and driving. Chance, too, is using his experience to educate others: "They just need to understand, don't do it. Don't do it. It's not worth losing your life."

Robot stock traders lose $440,000,000 in 45 minutes
Sent to you by diluted via Google Reader:
Humans never learn and apparently neither do robots. Autonomous trading AIs went on a spending spree at Knight Capital Group in New Jersey this week, buying up shares in everything from RadioShack to Ford and American Airlines (ouch) in a 45-minute frenzy of disobedience. The company tried to offload the unwanted stock, but discovered it was already nearly half a billion dollars in the red -- enough to wipe out its entire profit from 2011 and "severely impact" its ability to conduct business. If only it had protected itself with one of these.

Valve: L4D2 runs faster on Linux than on Windows
Sent to you by diluted via Google Reader:
From Valve's Linux blog: "That the Linux version runs faster than the Windows version (270.6) seems a little counter-intuitive, given the greater amount of time we have spent on the Windows version. However, it does speak to the underlying efficiency of the kernel and OpenGL." If it wasn't obvious before, it should be now: Valve has started its marketing campaign for Linux. With the Windows platform in the process of closing itself off, Valve has to look to greener pastures. This is all to motive third parties to get their stuff ready for a possible Linux-powered 'Steambox' - not a console, but a set of generic PC specifications. Remember: the Xbox is the only machine tied to DirectX - OpenGL runs everywhere else, including Windows (the PS3 is an oddball, and has a sort-of Sony-specific FrankenOpenGL). OpenGL simply makes more sense for developers, and now Valve is working very closely with Nvidia, AMD, and Intel to optimise their Linux drivers. Do the math, people.

Astronomers make sharpest observation ever of distant galaxy
Sent to you by diluted via Google Reader:
Astronomers just captured the sharpest and most direct look at a faraway galaxy, the bright quasar 3C 279, containing a supermassive black whole with a mass that's about one billion times the mass of our own Sun. The international team used three telescopes located thousands of miles apart from one another and was able to observe the galaxy at a sharpness of more than two million times finer than what the human eye can see. The galaxy is so far away, it takes more than 5 billion years for its light to reach Earth.
The telescopes were linked through a special technique called Very Long Baseline Interferometry (VLBI), allowing them to make sharper observations by acting as a single telescope as big as the separation between them, which were made as large as possible. The team created an interferometer with a 9,447-kilometer transcontinental baseline length from Chile to Hawaii, a 7,174-kilometer baseline length from Chile to Arizona and a 4,627-kilometer baseline length from Arizona to Hawaii.
Radio waves with wavelengths of 1.3 millimeters were used to make the observations. It was the first time that such short wavelengths with such long baselines had been used, returning an angular resolution of just 28 microarcseconds, or 8 billionths of a degree.
"The observations represent a new milestone towards imaging supermassive black holes and the regions around them," a statement from the European Southern Observancy said.
The sharp look at quasar 3C 279 is considered to be a big step toward an even larger project called the Event Horizon Telescope, which will aim to make even more powerful and longer baseline array. Eventually, it could show astronomers the shadow of the black hole from the middle of our own Milky Way galaxy.

Microsoft Apologizes For Inserting Naughty Phrase Into Linux Kernel
Sent to you by diluted via Google Reader:
netbuzz writes "Microsoft has apologized and promised to rectify the fact that one of its developers slipped a sexist phrase into Linux kernel code supporting Microsoft's HyperV virtualization environment. In that code, the magic constant passed through to the hypervisor reads '0xB16B00B5,' or a slightly camouflaged 'BIG BOOBS.' After Linux developer/blogger Matthew Garrett criticized Microsoft for the stunt, the predictable debate over sexism in the technology world ensued. Microsoft issued a statement to Network World apologizing and added, 'We have submitted a patch to fix this issue and the change will be published in a future release of the kernel.'"

US launches first commercial tidal power project this summer
Sent to you by diluted via Google Reader:
Solar may be the green energy source that's been hogging the headlines lately, but there are other fossil-fuel free ways that can help meet society's electrical needs. One of these is tidal power, and the US is set to start harnessing the ocean's electricity-generating potential this summer with the TidGen Cobscook Bay project -- the first such commercial project in the States. Located just off the coast of Eastport, Maine, turbines will be placed in 50-100 feet deep water to take advantage of the 100 billion tons of water that flow in and out of Cobscook Bay each day. When the project goes live, it'll feed into the public power grid and generate enough juice to power between 75 and 100 homes, and the plan is to eventually install enough turbines to generate 3MW of power -- which should cover the needs of over 1,000 homes and businesses. There's more info, plus plenty of political self-congratulation in the source below.
