One Screen, Multiple Views 43

First time accepted submitter e-sas writes "Researchers from the University of Bristol have built a new type of display which allows both a shared view and a personalised view to users at the same time. Through the two view-zones, PiVOT provides multiple personalized views where each personalized view is only visible to the user it belongs to while presenting an unaffected and unobstructed shared view to all users. They conceive PiVOT as a tabletop system aimed at supporting mixed-focus collaborative tasks where there is a main task requiring the focus of all individuals of the group but also concurrent smaller personal tasks needing access to information that is not usually shared e.g. a war-room setup. Imagine you and your friends playing multiplayer Starcraft on one big screen instead of individual computer screens!"

Swarm — a New Approach To Distributed Computation 80

An anonymous reader writes "Ian Clarke, creator of Freenet, has been working on a new open source project called Swarm. The concept is to allow a computer program to be distributed across multiple computers in a manner almost completely transparent to the programmer. The system observes the program executing and figures out how the workload should be distributed for maximum efficiency. Swarm is implemented in Scala. Its at an early-prototype stage, and Ian has created a good 36 minute video explaining the concept and the current implementation."

Google SideWiki Brings Comments To Everyone 221

Rophuine writes "Google has launched a product called SideWiki. It takes the form of a plug-in to Firefox and Internet Explorer which allows users to mark up the web by adding comments which can be seen by anyone else running SideWiki." Google's version joins a long line of attempts to impose a layer of comments on the Web, including Microsoft's Smart Tags and Third Voice.

We're In Danger of Losing Our Memories 398

Hugh Pickens writes "The chief executive of the British Library, Lynne Brindley, says that our cultural heritage is at risk as the Internet evolves and technologies become obsolete, and that historians and citizens face a 'black hole' in the knowledge base of the 21st century unless urgent action is taken to preserve websites and other digital records. For example, when Barack Obama was inaugurated as US president last week, all traces of George W. Bush disappeared from the White House website. There were more than 150 websites relating to the 2000 Olympics in Sydney that vanished instantly at the end of the games and are now stored only by the National Library of Australia. 'If websites continue to disappear in the same way as those on President Bush and the Sydney Olympics... the memory of the nation disappears too,' says Brindley. The library plans to create a comprehensive archive of material from the 8M .uk domain websites, and also is organizing a collecting and archiving project for the London 2012 Olympics. 'The task of capturing our online intellectual heritage and preserving it for the long term falls, quite rightly, to the same libraries and archives that have over centuries systematically collected books, periodicals, newspapers, and recordings...'" Over the years we've discussed various aspects of this archiving problem.

Experiment Shows Traffic 'Shock Waves' Cause Jams 642

Galactic_grub writes "Japanese researchers recently performed the first experimental demonstration of a phenomenon that causes a busy freeway to inexplicably grind to a halt. A team from Nagoya University in Japan had volunteers drive cars around a small circular track and monitored the way 'shockwaves' — caused when one driver brakes — are sent back to other cars, caused jams to occur. Drivers were asked to travel at 30 kmph but small fluctuations soon appeared, eventually causing several vehicles to stop completely. Understanding the phenomenon could help devise ways to avoid the problem. As one researcher comments: 'If they had set up an experiment with robots driving in a perfect circle, flow breakdown would not have occurred.'"

UK ISPs To Start Tracking Your Surfing To Serve You Ads 238

TechDirt has an interesting article about a UK-based company that is trying to work with ISPs to make use of user surfing data to serve targeted ads. "Late last year, we heard about a company that was trying to work with ISPs to make use of that data themselves to insert their own ads based on your surfing history -- and now we've got the first report of some big ISPs moving into this realm. Over in the UK three big ISPs, BT, Carphone Warehouse and Virgin Media have announced plans to use your clickstream data to insert relevant ads as you surf through a new startup called Phorm."
