The Best Robots of 2009 51

kkleiner writes "Singularity Hub has just unveiled its second annual roundup of the best robots of the year. In 2009 robots continued their advance towards world domination with several impressive breakouts in areas such as walking, automation, and agility, while still lacking in adaptability and reasoning ability. It will be several years until robots can gain the artificial intelligence that will truly make them remarkable, but in the meantime they are still pretty awesome."

Thanks for taking the time to write a thoughtful though flawed response. The thing is, I never mentioned Linux. Furthermore, I would say that the continued existence and popularity of the Apple Macintosh refutes the rest of your arguments hinging on ease of use and technical support. In fact you have perfectly illustrated the point that I am making here.

There was a time when doctors routinely prescribed smoking cigarettes as a quick and easy fix to all manner of ills. The long term hazards and effects weren't properly understood, and by the time they were, there was such a huge vested interest in perpetuating the smoking habit that the battle to remove it for the common good is still far from over, and may never be.

Likewise it is all too easy to facilitate yet another Windows installation, rather than risking your income by swimming against the tide. Even if you already know that the software that you are installing is inferior, you will go ahead and install it anyway, putting your own self interest ahead of those of your unfortunate clients.

As for the attitude of management towards this corruption that is so pervasive throughout the industry, I think a quote from one of my own past employers sums it up the best. "If we adopt this other more cost effective technology it will reduce my departmental budget and then Bob (the manager of another department) will get a better parking spot than me."

Yes, you do that.

Who knows, you could accomplish the space age equivalent of introducing syphilis to polynesia, or bring tobacco to civilisation.

But I expect that all you're really capable of doing is tearing up the sand dunes in your SUV, shooting stuff with guns, and leaving your empty beer cans behind.

So if you do go on a trip, don't come back.

Press Favored Obama Throughout Campaign 1601

narcberry writes "After complaints of one-sided reporting, the Washington Post checked their own articles and agreed. Obama was clearly favored, throughout his campaign, in terms of more favorable articles, less criticism, better page real-estate, more pictures, and total disregard for problems such as his drug use. 'Stories and photos about Obama in the news pages outnumbered those devoted to McCain. Reporters, photographers and editors found the candidacy of Obama, the first African American major-party nominee, more newsworthy and historic. Journalists love the new; McCain, 25 years older than Obama, was already well known and had more scars from his longer career in politics. The number of Obama stories since Nov. 11 was 946, compared with McCain's 786. Both had hard-fought primary campaigns, but Obama's battle with Hillary Rodham Clinton was longer, and the numbers reflect that. McCain clinched the GOP nomination on March 4, three months before Obama won his. From June 4 to Election Day, the tally was Obama, 626 stories, and McCain, 584. Obama was on the front page 176 times, McCain, 144 times; 41 stories featured both.'"

Australia Developing Massive Electric Vehicle Grid 260

blairerickson writes "A US firm Thursday unveiled plans to build a massive one-billion-dollar charging network to power electric cars in Australia as it seeks cleaner and cheaper options to petrol. Better Place, which has built plug-in stations for electric vehicles in Israel and Denmark, has joined forces with Australian power company AGL and finance group Macquarie Capital to create an Australian network. Under the plan, the three cities will each have a network of between 200,000 and 250,000 charge stations by 2012 where drivers can plug in and power up their electric cars. The points would probably be at homes and businesses, car parks and shopping centres. In addition, 150 switch stations will be built in each city and on major freeways, where electric batteries can be automatically replaced in drive-in stations similar to a car wash." I hope they're talking to the car companies about the necessary standardization it would take to make this work, too.

Unbelievably Large Telescopes On the Moon? 292

Matt_dk writes "A team of internationally renowned astronomers and opticians may have found a way to make "unbelievably large" telescopes on the Moon. 'It's so simple,' says Ermanno F. Borra, physics professor at the Optics Laboratory of Laval University in Quebec, Canada. 'Isaac Newton knew that any liquid, if put into a shallow container and set spinning, naturally assumes a parabolic shape, the same shape needed by a telescope mirror to bring starlight to a focus. This could be the key to making a giant lunar observatory.'"

Playing With Atomic Clocks At Home 167

Wired is running a profile of the Time Nuts, a small group of people who buy surplus precision time equipment — cesium clocks for example — on eBay and keep really accurate time, because they can. The article quotes Tom Van Baak, who has outfitted a time lab superior to those of many small countries: "If you have one clock... you are peaceful and have no worries. If you have two clocks... you start asking, 'What time is it, really?'"

Submission + - Bolivian Salt Flats Aid Spacecraft Calibration

PCOL writes: "Salar de Uyuni is a vast plain of white cemented salt in the mountains of Bolivia roughly 25 times the size of the Bonneville Salt Flats with a total elevation range of less than 80 centimeters making it the flattest place on earth. Beginning in 2002, Adrian Borsa, a geophysicist at the US Geological Survey in Pasadena, California, led the survey that resulted in precise GPS measurements of the salt flat, characterizing its elevation to an accuracy of 2.2 centimeters. "It's as if you're on a white ocean with no waves," says Borsa. "You see the horizon, the curvature of Earth. It's absolutely featureless." But what has been the salt flats attraction for scientists? The salt flats will be used as a giant calibration device for satellite-based radar and laser altimeters on the CryoSat recovery mission so the spacecraft can more precisely monitor changes in the elevation and thickness of polar ice sheets and floating sea ice. Salar de Uyuni is also one of the few terrestrial locations where gravitational fields are able to play a major role in shaping local ( 100 km) topography with a land surface that has been shown to undulate in step with earth's local gravitational field creating faint mounds of some 40 centimeters in height over regions of slightly higher gravity, owing to high-density volcanic rocks kilometers below. After taking out the elevation variations that are due to gravity, Borsa is so far seeing a strange, regularly patterned checkerboard surface that could reflect the imprint of periodic pressures due to prevailing winds. Working out the forces that produce this pattern could be useful if similar phenomena are ever spotted on another planet, says Borsa. "Now we've got an analogue on Earth.""
