Incorporating Swarm Intelligence Into Computer AI 64

Posted by Soulskill from the don't-show-this-to-the-left-4-dead-guys dept.
An anonymous reader writes "From optimizing truck delivery routes to inspiring nerve-cell-based cognition models, ant intelligence has arrived. From the Economist: 'In 1992 Dr. Dorigo and his group began developing Ant Colony Optimisation (ACO), an algorithm that looks for solutions to a problem by simulating a group of ants wandering over an area and laying down pheromones. ACO proved good at solving travelling-salesman-type problems. Since then it has grown into a whole family of algorithms, which have been applied to many practical questions. ... Ant-like algorithms have also been applied to the problem of routing information through communication networks. Dr. Dorigo and Gianni Di Caro, another researcher at IDSIA, have developed AntNet, a routing protocol in which packets of information hop from node to node, leaving a trace that signals the "quality" of their trip as they do so. Other packets sniff the trails thus created and choose accordingly. In computer simulations and tests on small-scale networks, AntNet has been shown to outperform existing routing protocols."

When Is It Right To Go Public With Security Flaws? 126

Posted by CmdrTaco from the yesterday dept.
nk497 writes "When it comes to security flaws, who should be warned first: users or software vendors? The debate has flared up again, after Google researcher Tavis Ormandy published a flaw in Windows Support. As previously noted on Slashdot, Google has since promised to back researchers that give vendors at least 60-days to sort out a solution to reported flaws, while Microsoft has responded by renaming responsible disclosure as 'coordinated vulnerability disclosure.' Microsoft is set to announce something related to community-based defense at Black Hat, but it's not likely to be a bug bounty, as the firm has again said it won't pay for vulnerabilities. So what other methods for managing disclosures could the security industry develop, that balance vendors need for time to develop a solution and researchers' needs to work together and publish?"

Porting Lemmings In 36 Hours 154

Posted by Soulskill from the first-in-line dept.
An anonymous reader writes "Aaron Ardiri challenged himself to port his classic PalmOS version of Lemmings to the iPhone, Palm Pre, Mac, and Windows. The porting was done using his own dev environment, which creates native C versions of the game. He liveblogged the whole thing, and finished after only 36 hours with an iPhone version and a Palm Pre version awaiting submission, and free versions for Windows and Mac available on his site."

Microsoft To Add Yet Another Smartphone OS This Year 179

Posted by timothy from the 5th-time's-the-charm dept.
GMGruman writes "Someone at Microsoft either really loves mobile operating systems or can't make up his mind as to which to use, because Microsoft Thursday announced yet another mobile OS, its fifth. The new Windows Embedded Handheld OS will succeed Windows Mobile 6.5 and run on at least some existing Windows Mobile smartphones. It is not the same mobile OS, known as Windows Phone 7, that Microsoft earlier this year said would replace Windows Mobile and break with it in terms of compatibility so Microsoft could better compete with the iPhone and Google Android OS."

Submission + - Why does saliva form beads when pulled thin? (sciencemag.org)

Submitted by cremeglace
cremeglace writes: Scientists have finally solved the most important problem that ever puzzled humankind: why does spit clump into beads when you pull it between your fingers? The answer has to do with polymers, or something. A better explanation--and a lovely picture--can be found at ScienceNOW.

Submission + - Giant planet 9x the size of Jupiter found (sciencemag.org)

Submitted by cremeglace
cremeglace writes: In the late 1990s, astronomers noticed a distinct warp in the disk of dust and gas orbiting a young star some 60 light-years from Earth. Now, using new analytical tools, researchers have discovered a giant planet lurking within the dusty haze. About nine times as massive as Jupiter and composed mainly of gas, the planet is only a few million years old, proving that such enormous planetary bodies can form rapidly.
