theodp writes "Many municipalities have switched to LED traffic signals because they burn brighter, last longer and use 90% less energy than incandescent bulbs. But they also emit less heat, meaning they sometimes have trouble melting snow, causing problems across the Midwest. In Wisconsin, snow blanketed LED traffic lights in some towns, leading to crashes at intersections where drivers weren't sure whether to stop or go. The unintended consequences of the green technology were also identified as a 'contributing factor' in the death of an Illinois woman hit by a driver who blamed the snow-covered energy-efficient signal for giving the appearance of a normal green light instead of a left-turn signal. 'We can remove the snow with heat, but the cost of doing that in terms of energy use has not brought any enthusiasm from cities and states that buy these signals,' said the CEO of an LED traffic-signal manufacturer. 'They'd like to be able to take away this issue, but they don't want to spend the money and lose the savings.' In the meantime, some towns are addressing sporadic problems by dispatching crews to remove snow or ice from signals using poles, brooms, and heating devices." We were discussing these recently at the office — several folks in the building are red/green color blind and different street lights are differently distinguishable.

theodp writes "Computerworld reports that a NJ Superior Court Judge ordered hosting firms to shut down three Web sites that oppose the H-1B visa program and seeks information about the identity of anonymous posters. GoDaddy, Network Solutions, Comcast and DiscountASP.Net were ordered to disable ITgrunt.com, Endh1b.com, and Guestworkerfraud.com. Facebook Inc. was also ordered to disable ITgrunt's Facebook page. The judge's order was made in response to a libel lawsuit filed by Apex Technology Group Inc., which is citing its copyright ownership as it seeks the identity of the poster of a since-removed Apex employment agreement on Docstoc.com, which drew critical comments on US and India websites."

mantis2009 writes "When it comes to stopping a cataclysmic Earth vs. asteroid event, social science and international political leaders have more difficult questions yet unanswered than physicists do, according to report delivered at this week's American Geophysical Union meeting. Wired has a discussion of an analysis authored by former astronaut Rusty Schweickart, who worries that the international community is nowhere near ready to begin the complex and inevitably controversial task of deflecting an asteroid on a collision course with Earth. Among the questions to be answered is whether to modify the Partial Test Ban Treaty to allow nuclear weapons in outer space. Another possibility to avoid the destruction of civilization would require the international community to choose an area on the globe where an asteroid might be 'aimed.' Who would decide which nations get placed in the asteroid's crosshairs?"

The Bad Astronomer writes "NASA's Cassini spacecraft took an image of Saturn's giant moon Titan earlier this year that serendipitously provides proof of liquid (probably methane) on its surface. The picture shows a glint of reflected sunlight off of a monster lake called Kraken Mare (larger than the Caspian Sea!). Scientists have been getting better and better evidence of liquid methane on Titan, but this is the first direct proof."

itwbennett writes "Do geeks really 'drive girls out of computer science,' as the headline of a LiveScience article contends? Blogger Cameron Laird doesn't think so. In fact, 'I don't think "gender issues in computing" is important enough to merit the attention it gets,' says Laird in a recent post. And maybe the problem isn't that there are too few women in computing, but that there are too many men. 'I'm waiting to read the headline: "Women too smart for careers with computers,"' says Laird, 'where another researcher concludes that only "boys" are stupid enough to go into a field that's globally-fungible, where entry-level salaries are declining, and it's common to think that staying up all night for a company-paid pizza is a good deal.'"

darthvader100 writes "Gizmodo has run an article with some predictions on what future space battles will be like. The author brings up several theories on propulsion (and orbits), weapons (explosives, kinetic and laser), and design. Sounds like the ideal shape for spaceships will be spherical, like the one in the Hitchhiker's Guide movie."

An anonymous reader writes "About fifteen years ago, I did something that I've come to regret on a university computer system. I was subsequently interviewed by a Federal law enforcement agency, although no charges were pressed and I have no criminal record as a result of my actions. At the time, I discussed the matter with a friend of mine who went on to mention it briefly in a text file zine with a small distribution list. I've generally tried to keep a low profile online and until recently there's been very little information about me available from the major search engines. Unfortunately, that zine mention was picked up by textfiles.com at some point and mirrored across the world. I've tried to address this with the owner of the site, but couldn't get anywhere. Even if my name in the source file is altered, cached copies will continue to link me with my youthful mistake. Have any other Slashdot readers had a similar experience? What practical steps would your readers recommend to prevent this information from hurting me? I am concerned that future employers may hold my past actions against me should they look for me online as part of their screening process."

Aspiritech, a Chicago based non-profit company, has launched a program to train high-functioning autistic people as testers for software development companies. The company says autistics have a talent for spotting imperfections, and thrive on predictable, monotonous work. Aspiritech is not the first company to explore the idea of treating this handicap as a resource. Specialisterne, a Danish company founded in 2004, also trains autistics. They hire their workforce out as hourly consultants to do data entry, assembly line jobs and work that many would find tedious and repetitive.

jshamacher writes "I've used MythTV for several years (first on Slackware, now via Mythbuntu) and it's good. But not great — I have a list of annoyances as long as my arm. For example, even 0.22 still has problems playing many DVDs and I frequently have to fall back on Xine. Since upgrading to new hardware, I've had issues with sound dropping out; these problems only occur for Myth, not for anything else. So now I'm trying out alternatives. Freevo seemed promising when I tried it a few months ago but it had its own issues. I'm also increasingly getting pressure from my family to get things like NetFlix streaming working on this machine. This seems to imply migrating to a Windows-based solution. I threw XP on it and tried MediaPortal but could never get that to control my Motorola cable box via the IR blaster. So my questions to you: What DVR software do you use? Are you happy with it? What don't you like? Are there any packages out there that 'just work' as media hubs and for time-shifting cable TV?"

compumike writes "What geek among us has never thought about how cool it would be if you could call your computer and have it do stuff? Josh Davis put together a quick video demo and source code of his Voice Controlled LED Marquee, powered by Google Voice speech recognition and a DIY LED Array Kit. Imagine using the same display for monitoring server uptime, or RSS feeds!"

antdude writes "The New York Times' Well blog reports that 'for some time, researchers have been finding that people who exercise don't necessarily lose weight.' A study published online in September 2009 in The British Journal of Sports Medicine was the latest to report apparently disappointing slimming results. In the study, 58 obese people completed 12 weeks of supervised aerobic training without changing their diets. The group lost an average of a little more than seven pounds, and many lost barely half that. How can that be?"

samzenpus writes "A restricted 2,400 page-document put out by the MoD designed to help intelligence personnel with information security has been leaked onto the internet. Wikileaks notes that Joint Services Protocol 440 (JSP 440), was published in 2001 and lays out protocols to defend against hackers, journalists, and foreign spies. it says, 'Leaks usually take the form of reports in the public media which appear to involve the unauthorized disclosure of official information (whether protectively marked or not) that causes political harm or embarrassment to either the UK Government or the Department concerned... The threat [of leakage] is less likely to arise from positive acts of counter-espionage, than from leakage of information through disaffected members of staff, or as a result of the attentions of an investigative journalist, or simply by accident or carelessness.' " Looks like it's time to write JSP 441.

The Optimizer writes "After 16 years of service, my laser printer, a NEC Silentwriter 95, is finally wearing its internals out, and I need to find a replacement. It's printed over 30,000 pages and survived a half-dozen long-distance moves without giving me any trouble. I believe it's done so well for two reasons. First, it's sturdily built and hails from an era when every fraction of a penny didn't have to be cost-cut out of manufacturing. The other reason was its software. Since it supported postscript Level II, it wasn't bound to a specific operating system or hardware platform, so long as a basic postscript level 2 driver was available. A new color laser printer with postscript 3 seems like a logical replacement, and numerous inexpensive printers are available. I'd rather get a smaller, personal-size printer than a heavy workgroup printer. Most of all, I would like it to still be usable and running well with Windows 9, OS X 11, and whatever else we will be using in 2020. Can anyone recommend a brand or series of printers that is built to last and isn't going to be completely dependent on OS specific proprietary drivers?"
