Comment Re:What does the wasp do with it? (Score 1) 177

From the original paper:

The xanthopterin pigment found within the cuticle has been proven to be a suitable absorber of light for the harvesting of solar energy by a demonstration of its use in an organic solar cell, with a conversion efficiency of 0.335%.

I assume this was just a "proof of concept" organic solar cell, so the efficiency could probably be increased, but 0.335% doesn't sound like much!

Submission + - Programming Things I Wish I Knew Earlier 1

theodp writes: Raw intellect ain't always all it's cracked up to be, advises Ted Dziuba in his introduction to Programming Things I Wish I Knew Earlier, so don't be too stubborn to learn the things that can save you from the headaches of over-engineering. Some sample how-to-avoid-over-complicating-things advice: 'If Linux can do it, you shouldn't. Don't use Hadoop MapReduce until you have a solid reason why xargs won't solve your problem. Don't implement your own lockservice when Linux's advisory file locking works just fine. Don't do image processing work with PIL unless you have proven that command-line ImageMagick won't do the job. Modern Linux distributions are capable of a lot, and most hard problems are already solved for you. You just need to know where to look.' Any cautionary tips you'd like to share from your own experience?

Nokia Trades Symbian For MeeGo In N-Series Smartphones 184

An anonymous reader writes "Nokia announced that moving forward, MeeGo would be the default operating system in the N series of smartphones (original Reuters report). Symbian will still be used in low-end devices from Nokia, Samsung, and Sony Ericsson. The move to MeeGo is a demonstration of support for the open source mobile OS, but considering the handset user experience hasn't been rolled out and likely won't be rolled out in time for its vague June deadline outlined at MeeGo.com, could the decision be premature?"

Microsoft Kills Support For XP SP2 315

Trailrunner7 writes "Microsoft's announcement this week that it is preparing to end support for machines running Windows XP SP2 not only represents a challenge for the thousands of businesses still running SP2, but also is the end of an era for both Microsoft and its customers. It wasn't until 2004 that the final release of XP SP2 hit the streets, but when it did, it represented a huge step forward in security for Windows users. It wasn't necessarily the feature set that mattered as much as the fact that the protections were enabled by default and taken out of the users' hands."

Beijing Sweetens Rubbish With Giant Deodorant Guns 111

An anonymous reader writes "Beijing plans to install 100 deodorant guns at a landfill site on the edge of the city in the hopes that it will dampen complaints about the capital's rubbish crisis.The giant fragrance sprayers will be put in place by May at the Asuwei dump site. From the article: 'Municipal authorities say they will also apply more plastic layers to cover the site in response to furious protests by local residents who have to put up with the stench when the wind blows in their direction. The high-pressure guns, which can spray dozens of litres of fragrance per minute over a distance of up to 50m, are produced by several Chinese firms and based on German and Italian technology. They are already in use at several landfill sites, but they are merely a temporary fix.'"

Why the First Cowboy To Draw Always Gets Shot 398

cremeglace writes "Have you ever noticed that the first cowboy to draw his gun in a Hollywood Western is invariably the one to get shot? Nobel-winning physicist Niels Bohr did, once arranging mock duels to test the validity of this cinematic curiosity. Researchers have now confirmed that people indeed move faster if they are reacting, rather than acting first."

7 of the Best Free Linux Calculators 289

An anonymous reader writes "One of the basic utilities supplied with any operating system is a desktop calculator. These are often simple utilities that are perfectly adequate for basic use. They typically include trigonometric functions, logarithms, factorials, parentheses and a memory function. However, the calculators featured in this article are significantly more sophisticated with the ability to process difficult mathematical functions, to plot graphs in 2D and 3D, and much more. Occasionally, the calculator tool provided with an operating system did not engender any confidence. The classic example being the calculator shipped with Windows 3.1 which could not even reliably subtract two numbers. Rest assured, the calculators listed below are of precision quality."
