Game Over For Sony and Open Source? 364

Posted by Soulskill from the forsaken-beards dept.
Glyn Moody writes "Sony has never been much of a friend to hackers, and its infamous rootkit showed what it thought of users. But by omitting the option to install GNU/Linux on its new PS3, it has removed the final reason for the open source world to care about Sony. Unless, of course, you find Google's new distribution alliance with Sony to pre-install Chrome on its PCs exciting in some way."

Relativistic Navigation Needed For Solar Sails 185

Posted by Soulskill from the i'd-rather-be-sailing dept.
KentuckyFC writes "Last year, physicists calculated that a solar sail about a kilometer across with a mass of 300 kg (including 150 kg of payload) would have a peak acceleration of roughly 0.6g if released about 0.1AU from the Sun, where the radiation pressure is highest. That kind of acceleration could take it to the heliopause — the boundary between the Solar System and interstellar space — in only 2.5 years; a distance of 200 AU. In 30 years, it could travel 2500AU, far enough to explore the Oort Cloud. But the team has discovered a problem. Ordinary Newtonian physics just doesn't cut it for the kind of navigational calculations needed for this journey. Because the sail has to be released so close to the Sun, it becomes subject to the effects of general relativity. And although the errors these introduce are small, they become magnified over the course of a long journey, sending the sail roughly 1 million kilometers off course by the time it reaches the Oort Cloud. What these guys are saying is that if ever such a sail is launched (and the earliest estimate is 2040), the navigators will have to be proficient in a new discipline of relativistic navigation."

IRS Looking at Google/Mozilla Relationship 261

Posted by CmdrTaco from the can't-imagine-why dept.
ric482 writes "With the release of the Mozilla Foundation's 2007 financial report, questions have been raised by the IRS, who are due to perform an audit on the non-profit organization behind the massively popular Firefox browser. Last year, the Foundation received $66 million of its total $75 million revenue (88 percent) from search engine maestros Google, so the IRS are looking for blood over the organization's tax exempt status. Back in 2006, Mozilla got $59.5 million from Google — around 85 percent of the organization's revenue. Google and Mozilla are part of a 'you scratch my back, I'll pay your bills' sort of agreement, with the Google search bar firmly placed in the toolbar, and on the default homepage. Things were a bit rocky a couple of months back when Google unveiled the Beta-run of its Chrome browser, but Mozilla and Google hugged it out and sealed a deal that will last for another three years. That deal will expire in November 2011."
