Ken Stanley writes "Just as interest in user-generated content in video games is heating up, a team of researchers at the University of Central Florida has released an experimental multiplayer game in which content items compete with each other in an evolutionary arms race to satisfy the players. As a result, particle system-based weapons, which are the evolving class of content, continually invent their own new behaviors based on what users liked in the past. Does the resulting experience in this game, called Galactic Arms Race, suggest that evolutionary algorithms may be the key to automated content generation in future multiplayer gaming and MMOs?"

goran72 writes "A new image, taken with an infrared camera on the Subaru Telescope in Hawaii, has revealed a cosmic fireworks display, in the form of tens of thousands of previously unseen comet-shaped knots inside the Helix Nebula. Unlike previous optical images of the Helix Nebula knots, the infrared image shows thousands of clearly resolved knots, extending out from the central star at greater distances than previously observed. These images enable astronomers to estimate that there may be as many as 40,000 knots in the entire nebula, each of which are billions of kilometers/miles across. Their total mass may be as much as 30,000 Earths, or one-tenth the mass of our Sun."

In 1987, a study published by Jim Gray and Gianfranco Putzolu evaluated the trade-offs between holding data in memory and storing it on a disk. Known widely as the "five-minute rule," their research was updated and expanded 10 years later. Now, as jamie points out, Communications of the ACM is running an article by Goetz Graefe with another decennial update, evaluating the rule using hardware and software typical of 2007, with an eye toward how flash memory will affect the situation. An excerpt from Graefe's conclusion: "The 20-year-old five-minute rule for RAM and disks still holds, but for ever-larger disk pages. Moreover, it should be augmented by two new five-minute rules: one for small pages moving between RAM and flash memory and one for large pages moving between flash memory and traditional disks. For small pages moving between RAM and disk, Gray and Putzolu were amazingly accurate in predicting a five-hour break-even point two decades into the future. Research into flash memory and its place in system architectures is urgent and important. Within a few years, flash memory will be used to fill the gap between traditional RAM and traditional disk drives in many operating systems, file systems, and database systems."

schliz writes "Researchers behind the world's largest quantum encrypted network said the technology could secure business networks inside six years. The prototype Quantum Key Distribution network was built by the Secure Communication Based On Quantum Cryptography (SECOQC) group last year. It is described in a journal paper published by the Institute of Physics this week, which includes details on how it is based on the trusted-repeater paradigm."

Michael J. Ross writes "Two decades ago, Web usage was limited to a single individual (Sir Tim Berners-Lee) using the only browser in existence (WorldWideWeb) running on a single platform (a NeXT Computer). Nowadays, billions of people access the Web daily, with the ability to choose from over a dozen browsers running on desktop computers, laptops, and a variety of mobile devices, such as cell phones. The number of possible combinations is growing rapidly, and makes it increasingly difficult for Web designers and developers to craft their sites so as to be universally accessible. This is particularly true when accounting for Web users with physical and cognitive disabilities — especially if they do not have access to assistive technologies. The challenges and solutions for anyone creating an accessible website are addressed in Universal Design for Web Applications, authored by Wendy Chisholm and Matt May."

Nicola Hahn writes "One of the first things I noticed while flipping through this hefty book is the sheer number of topics covered. Perhaps this is a necessity. As the author puts it, rootkits lie "at the intersection of several related disciplines: computer security, forensics, reverse-engineering, system internals, and device drivers." Upon closer inspection, it becomes clear that great pains have been taken to cover each subject in sufficient depth and to present ideas in a manner that's both articulate and well organized. This accounts for the book's girth; it weighs in at roughly 900 pages." Keep reading for the rest of Nicola's review.

FutureDomain writes "The Boston College Campus Police have seized the electronics of a computer science student for allegedly sending an email outing another student. The probable cause? The search warrant application states that he is 'a computer science major' and he uses 'two different operating systems for hiding his illegal activity. One is the regular B.C. operating system and the other is a black screen with white font which he uses prompt commands on.' The EFF is currently representing him."

Hugh Pickens writes "The British government's Office of Security and Counter-Terrorism (OSCT), a 200-strong Home Office unit created 18 months ago, has said in meetings it wants to 'flood the internet' with 'positive' interpretations of Islam and plans to train government-approved groups in search engine optimization techniques, which it is hoped will boost their profile online and battle radicalization. A Home Office spokesman confirmed search engine optimization training is part of the government's anti-radicalization strategy. 'In order to support mainstream voices, we work with local partners to help develop their communication, representational and leadership skills. This support could include media training, which can help make their voices heard more widely, and support the development of skills which allow communities to be more effective in debate.' However the effectiveness of search engine optimization in reducing traffic to extremist websites has been dismissed by academics. A report produced by the International Centre for the Study of Radicalisation (ICSR) said young Muslims were much more likely to be directed to extremist material online by web forums and offline associates than by Google or other search engines. 'Tweaking the results for supposedly extremist terms would be largely ineffectual, not least because it is unlikely that any but the most callow wannabe terrorist would use a mainstream search engine to find banned material.'"

Anonymous writes "Two graduate students at the Ivy League's Brown University built a P2P system to use abandoned wiki sites to store data. The students were stealing bandwidth from open MediaWiki sites to send data between users as an alternative to BitTorrent. There was immediate backlash as site operators quickly complained to the University. The project appears to be shutdown, but many of the pages still remain on the web. The project homepage was also taken down and the students posted an apology this afternoon." The same submitter links to two different forum discussions on the project.
