UK File-Sharing Laws Unenforceable On Mobile Networks 130

Posted by kdawson from the p2p-ringtones dept.
superglaze writes "UK mobile broadband providers currently have no way of telling which subscribers are file-sharing which copyrighted content, ZDNet UK reports. This represents something of a problem for new laws that have been proposed to crack down on unlawful file-sharing. According to the article, databases (tracking IP address mappings) could be built to make it possible to identify what specific users are downloading, but the industry is loathe to fund this sort of project itself. Also, as an analyst points out in the piece, users of prepaid phone cards are mostly anonymous in the UK, which creates another challenge for the government's plans. And if that isn't enough, connection-sharing apps like JoikuBoost would make identification pretty much impossible anyway."

New Theory of Gravity Decouples Space & Time 575

Posted by kdawson from the paging-hal-clement dept.
eldavojohn writes "Petr Horava, a physicist at the University of California in Berkeley, has a new theory about gravity and spacetime. At high energies, it actually snips any ties between space and time, yet at low energies devolves to equivalence with the theory of General Relativity, which binds them together. The theory is gaining popularity with physicists because it fits some observations better than Einstein's or Newton's solutions. It better predicts the movement of the planets (in an idealized case) and has a potential to create the illusion of dark matter. Another physicist calculated that under Horava Gravity, our universe would experience not a Big Bang but a Big Bounce — and the new theory reproduces the ripples from such an event in a way that matches measurements of the cosmic microwave background."

Would You Use a Free Netbook From Google? 435

Posted by timothy from the google-i-opener dept.
Glyn Moody writes "The response to Google's Chromium OS has been rather lukewarm. But suppose it's just part of something much bigger: a netbook computer from Google that would cost absolutely nothing. Because all the apps and data are stored in the cloud, storage requirements would be minimal; screens are getting cheaper, and the emphasis on lean code means that a low-cost processor could be used. Those relatively small hardware costs could then be covered by advertising in the apps — after all, they are just Web pages. Interestingly, Google has not only rolled out advertising to more of its services recently, it has also started running AdSense ads in the desktop application Google Earth. Would you accept a free Google netbook — or is the price you would pay in terms of the company knowing even more about what you do on an hour-by-hour basis just too high?"

New Binary Diffing Algorithm Announced By Google 192

Posted by timothy from the smartness-and-light dept.
bheer writes "Today Google's Open-Source Chromium project announced a new compression technique called Courgette geared towards distributing really small updates. Courgette achieves smaller diffs (about 9x in one example) than standard binary-diffing algorithms like bsdiff by disassembling the code and sending the assembler diffs over the wire. This, the Chromium devs say, will allow them to send smaller, more frequent updates, making users more secure. Since this will be released as open source, it should make distributing updates a lot easier for the open-source community."
