Submission + - Boeing Building an Enormous Laser for the US Navy (discovermagazine.com)

An anonymous reader writes: Boeing is working to build a huge, incredibly powerful, soon-to-be-seafaring laser for the US Navy. This free electron laser can produce light of any wavelength (ie, color) directly from an electron beam, and gets an energy boost from a superconducting particle accelerator. Once it's onboard ships, the laser could be used to shoot down cruise missiles and artillery shells.

Inside the Mechanical Turk Sweatshop 267

Barence writes "PC Pro has investigated the appalling rates of pay on offer from online services such as Amazon's Mechanical Turk, YouGov surveys and affiliate schemes. One Mechanical Turk task the writer tried involved finding the website, physical addresses and phone numbers of hotels for a travel website, for only $0.01 per hotel. The details often took more than a minute to locate, which equates to a rate of around $0.60 an hour, barely enough to cover the electricity bill. Meanwhile, filling out surveys for YouGov generates a maximum income of £3 an hour, and you could end up waiting more than a year for your cheque to arrive, because the site only pays out when you reach £50. 'The result is often that those who carry out online or casual work do so for surprisingly low rates of pay, with no job security or protection from unfair terms and practices,' an employment lawyer told PC Pro."

Volkswagen Creates Sewage-Powered Beetle Screenshot-sm 83

Hugh Pickens writes "The Telegraph reports that Volkswagen is giving new meaning to the term 'Dung Beetle' with a prototype able to cover 10,000 miles annually on the waste from 70 households. The Bio-Bug was launched by Wessex Water, which is generating methane from human waste at a sewage treatment works near Bristol. 'Our site has been producing biogas for many years, which we use to generate electricity to power the site and export to the National Grid,' says one company official. 'We decided to power a vehicle on the gas, offering a sustainable alternative to using fossil fuels which we so heavily rely on in the UK.' The Anaerobic Digestion and Biogas Association says the launch of the Bio-Bug proves that biomethane from sewage sludge can be used as fuel. 'This is a very exciting and forward-thinking project demonstrating the myriad benefits of anaerobic digestion (releasing energy from waste). Biomethane cars could be just as important as electric cars.'"

A Hyper-Velocity Impact In the Asteroid Belt? 114

astroengine writes "Astronomers have spotted something rather odd in the asteroid belt. It looks like a comet, but it's got a circular orbit, similar to an asteroid. Whether it's an asteroid or a comet, it has a long, comet-like tail, suggesting something is being vented into space. Some experts think it could be a very rare comet/asteroid hybrid being heated by the sun, but there's an even more exciting possibility: It could be the first ever observation of two asteroids colliding in the asteroid belt."

Music By Natural Selection Screenshot-sm 164

maccallr writes "The DarwinTunes experiment needs you! Using an evolutionary algorithm and the ears of you the general public, we've been evolving a four bar loop that started out as pretty dismal primordial auditory soup and now after >27k ratings and 200 generations is sounding pretty good. Given that the only ingredients are sine waves, we're impressed. We got some coverage in the New Scientist CultureLab blog but now things have gone quiet and we'd really appreciate some Slashdotter idle time. We recently upped the maximum 'genome size' and we think that the music is already benefiting from the change."

Chinese Automaker Unveils First Electric Car 341

JuliusSu writes "A Chinese auto manufacturer, BYD, is introducing today the country's first electric car, a plug-in hybrid vehicle. It plans to sell at least 10,000 cars in 2009 for a price of less than $22,000. This put the company ahead of schedule against other entrants to this market, such as Toyota, due to release a similar car in late 2009; and GM, whose Chevy Volt will be launched in late 2010. The company is best known for making cellphone batteries, and hopes its expertise in ferrous battery technology will allow it to leapfrog established car manufacturers."

Finding Better Tech Broadcasts? 205

BearGrylls writes "As a young lad and aspiring technologist I have found shows like Revision3's 'The Broken' and 'Systm' to be entertaining, informative, and, most importantly, thorough. As time has gone on revision3 has kept some of the tech-related shows, but dumbed them down to appeal to a larger audience. This annoyed me, but I've continued to be a loyal viewer of their tech shows anyway. However, I suspect this trend to continue and my disappointment to grow. Where can I find tech shows that dive deep into projects and discussions instead of simply skimming the surface?"

US Responsible For the Majority of Cyber Attacks 205

Amber G5 writes "SecureWorks published the locations of the computers from which the greatest number of cyber attacks were attempted against its clients in 2008. The United States topped the list with 20.6 million attempted attacks originating from computers within the country, and China ran second with 7.7 million attempted attacks emanating from computers within its borders. This was followed by Brazil with over 166,987 attempted attacks, South Korea with 162,289, Poland with 153,205, Japan with 142,346, Russia with 130,572, Taiwan with 124,997, Germany with 110,493, and Canada with 107,483."

it is hard to switch back to a binary distro after gentoo, but the parent has a point in that gentoo gets harder and harder to manage. That's why I started looking for alternatives and found Gobolinux, a distro that makes it really easy for mantainers and admins. It is a fresh air in the unix world.
