UK Commissioner Seeks To Ban Ultrasonic Anti-Teen Device 552

mikesd81 points out a Times Online article that discusses the legality of the Mosquito sound device, which is used to annoy and drive off younger people with sounds that are too high-pitched for most adults to hear. We discussed how annoying this device can be a couple years ago. From Times Online: "Sir Albert Aynsley-Green, the Children's Commissioner for England appointed to represent the views of the country's 11 million children, has set up a campaign — called Buzz Off — that is calling for the Mosquito to be banned on grounds that it infringes the rights of young people. 'These devices are indiscriminate and target all children and young people, including babies, regardless of whether they are behaving or misbehaving,' Sir Al told the BBC. 'The use of measures such as these are simply demonizing children and young people, creating a dangerous and widening divide between the young and the old.'"

Is the LUG a thing of the past? 162

tinahdee writes "Linux User Groups dying out? LUG leaders report that attendance is down — but mailing list traffic is still good. Do we still need LUGs, given the ease of installation and ubiquitousness of online information about Linux? Lots of people say, yes, we still need LUGs (and some disagree)."

Faster P2P By Matching Similiar Files? 222

Andreaskem writes "A Carnegie Mellon University computer scientist says transferring large data files, such as movies and music, over the Internet could be sped up significantly if peer-to-peer (P2P) file-sharing services were configured to share not only identical files, but also similar files. "SET speeds up data transfers by simultaneously downloading different chunks of a desired data file from multiple sources, rather than downloading an entire file from one slow source. Even then, downloads can be slow because these networks can't find enough sources to use all of a receiver's download bandwidth. That's why SET takes the additional step of identifying files that are similar to the desired file... No one knows the degree of similarity between data files stored in computers around the world, but analyses suggest the types of files most commonly shared are likely to contain a number of similar elements. Many music files, for instance, may differ only in the artist-and-title headers, but are otherwise 99 percent similar.""

Combined Hovercraft and Helicopter 254

An anonymous reader writes "Has British engineer Geoff Hatton brought us the best of two worlds with his UFO-looking machine? The US military thinks so and are investing in it. The design is sturdy (as opposed to a helicopter) and can fly high (as opposed to a hovercraft). It is based on the Coanda Effect."

Detecting Conflict-Of-Interest on the Semantic Web 34

CexpTretical writes "At the 15th International WWW Conference in Edinburgh Scotland, Refereed Track on Semantic Web accepted many thorough and interesting academic papers on semantic web research on subjects related to where the Web is in the Semantic Web? One such paper nominated for Best Paper Award, Semantic Analytics on Social Networks: Experiences in Addressing the Problem of Conflict of Interest Detection hits on the whole subject of validation and/or verification in the brave world of so called "Web 3.0" topologies/frameworks/architectures. The paper describes a "Semantic Web application that detects Conflict of Interest (COI) relationships"."
