Roland Piquepaille writes "Particle swarm optimization (PSO) is a computer algorithm based on a mathematical model of the social interactions of swarms which was first described in 1995. Now, researchers in the UK and Jordan have carried this swarm approach to photography to 'intelligently boost contrast and detail in an image without distorting the underlying features.' This looks like a clever concept even if I haven't seen any results. The researchers have developed an iterative process where a swarm of images are created by a computer. These images are 'graded relative to each other, the fittest end up at the front of the swarm until a single individual that is the most effectively enhanced.'"

Billosaur writes "A potentially disastrous 40-year-old mystery has been solved: Where is asteroid 6344 P-L? Back in 1960, asteroid 6344 P-L was identified and classified as a 'Potentially Hazardous Asteroid,' meaning that its orbit brings it perilously close to Earth's orbit (on the cosmic scale). Unfortunately, it then disappeared, or more precisely, was lost from view. Flash forward to 2007 and scientists believe that 6344 P-L has been rediscovered as 2007 RR9. Further, they are not sure it is an actual asteroid, but actually a comet fragment, which won't hit the Earth anytime soon but bears watching."

An anonymous reader writes "Opera 9.10 released in December seemed to be a rather cosmetic update. But as heise Security reports, behind the scenes Opera patched two remote code execution holes — neither of them mentioned in the changelog. In addition, Opera rates an exploitable heap overflow as 'moderate' because it is 'not trivial to exploit it reliably'. From the article: 'JPEG images can be specially prepared to cause a buffer overflow on the heap. Even though Opera suggests in the heading to its security notice that this problem only causes the browser to crash, the flaw can nonetheless be exploited to inject and execute code. Security service provider iDefense, which reported the hole to Opera, has confirmed this. The same holds true for a flawed type conversion in the JavaScript support for Scalable Vector Graphics (SVG). Attackers can specially call the function createSVGTransformFromMatrix to have the browser execute code with the user's rights.'"

Roland Piquepaille writes "Ohio University physicists have used a simple molecule of chlorophyll taken from spinach to develop a complex nanobiological switch. They used a scanning tunneling microscope (STM) to image chlorophyll-a and then injected it with a single electron to manipulate the molecule into four positions. The researchers say this biological switch might be used in future applications for green energy, technology and medicine. Read more for additional pictures and references about this spinach-based biological switch."

An anonymous reader writes "Even with all these exploding Dell notebooks and other notebook safety problems, Apple has seemed relatively immune. Every once in a while, some odd thing came along, but it seemed like relatively calm waters. Not anymore — Apple's notebook power adapters appear to be the source of some serious safety concerns. Every iBook and PowerBook user should read this and keep a close eye on their adapter — the adapters suffer from very poor design including wires that seem prone to short out and burn and zero short circuit protection."

Beuno writes "I stumbled upon a GeForce vs Radeon review on Tom's Hardware, which seems normal enough. The big surprise is that it was actually a comparison of those two video cards on Linux (Fedora Core 5). The review isn't as thorough as I would like, but it does review all aspects ranging from tools available, complexity of getting them to work and benchmarks on performance. To me, this is a clear signs of Linux finally making a long expected breakthrough into common desktops."

Tom's Hardware has posted the detailed results of their recent quest to build a beefy gaming rig without a visit to the poorhouse. The trick it seems is to find a processor with 'cores designed for a much faster clock than their nominal rating at a speed of up to 4 GHz without problems.' They provide shopping lists for both a 'budget version' and a 'top flight version'.

Blue6 writes "An addiction center is opening Europe's first detox clinic for game addicts, offering in-house treatment for people who can't leave their joysticks alone. Video games may look innocent, but they can be as addictive as gambling or drugs, and just as hard to kick, says Keith Bakker, director of Amsterdam-based Smith & Jones Addiction Consultants." I'm pretty sure the amount of time I've spent in the world of Azeroth in the past year counts as addiction. Someone tell my parents I still love them, while I mine this ore.

prostoalex writes "The weekend is here, and several software sites have published extensive reviews of Windows Vista for your reading enjoyment. Tom's Hardware is running a 500 hour Windows Vista review that spreads out 40 pages." From the article: "This new operating system is huge: it has more than 37,800 files, taking up a total of 10 GB. Part of this size stems from the fact that the current Beta is for the so-called "Ultimate Edition", which contains all available components, including complete versions of both Tablet PC and Media Center capabilities. In addition, many applications have been compiled in debug mode, so some space savings should occur for final versions once that debug switch is turned off. For our Windows Vista preview, we used Build 5381."

thatedeguy writes "The NY Post is reporting that Microsoft and Ebay are in talks for the online auction house to join the Microsoft family." That said, the talks aren't going that well at the moment. From the article: " Sources indicate that the talks, while still active, have cooled somewhat in the last two weeks as executives considered antitrust issues. It is unclear what the full impact of yesterday's advertising and search alliance between Yahoo! and eBay will be for talks between MSN and eBay. One source close to the matter suggested the Yahoo-eBay tie-up would not stop Microsoft from pursuing the online auctioneer."

stockpicker_dude_78 writes "Robert Cringley has written a thought-provoking article on Google's insular nature, and compares them to the similar environment at Microsoft." From the article: "Google is secretive. This started as a deliberate marketing mystique, but endures today more as a really annoying company habit. Google folks don't understand why the rest of us have a problem with this, but then Google folks aren't like you and me. The result of this secrecy and Google's 'almighty algorithm' mentality is that the company makes changes -- and mistakes -- without informing its customers or even doing all that much to correct the problems."

GenieGenieGenie writes "AP is running a story about Webroot's Spy Sweeper, specifically about the competition it's facing from Vista's bundled anti-spyware. Webroot's CEO David Moll maintains that 'The taking of a second-best product in this space [i.e. Vista's Defender, f.k.a. AntiSpyware] is akin to locking half the doors in your house,' but others seem to think that if Moll doesn't want his company to become a second Netscape, it would 'ultimately [...] need to offer more than just an anti-spyware package.' The interesting issue here is whether this need for broadening the offer would be the case also for other leading companies subject to similar 'bundled-with' competition."
