as long as people keep publishing on v4 -- or rather, as long as they don't publish stuff on v6 -- carriers are stuck with v4. Maybe one day ... or maybe someone will make trillions by selling a ridiculous amount of dual-stack reverse proxies.

Submission + - SPAM: Not Enough Women In Computing?

Submitted by itwbennett on Thursday December 17, 2009 @03:27PM

itwbennett writes: Do geeks really 'drive girls out of computer science,' as the headline of a LiveScience article contends? Blogger Cameron Laird doesn't think so. In fact, 'I don't think 'gender issues in computing' is important enough to merit the attention it gets,' says Laird in a recent post. And maybe the problem isn't that there are too few women in computing, but that there are too many men. 'I'm waiting to read the headline: 'Women too smart for careers with computers,' says Laird, 'where another researcher concludes that only 'boys' are stupid enough to go into a field that's globally-fungible, where entry-level salaries are declining, and it's common to think that staying up all night for a company-paid pizza is a good deal.'

PhD Candidate Talks About the Physics of Space Battles 361

Posted by samzenpus on Thursday December 17, 2009 @03:18PM from the load-photon-torpedoes dept.

darthvader100 writes "Gizmodo has run an article with some predictions on what future space battles will be like. The author brings up several theories on propulsion (and orbits), weapons (explosives, kinetic and laser), and design. Sounds like the ideal shape for spaceships will be spherical, like the one in the Hitchhiker's Guide movie."

The Perfect Way To Slice a Pizza 282

Posted by samzenpus on Tuesday December 15, 2009 @01:09PM from the equal-distribution-of-the-pie dept.

iamapizza writes "New Scientist reports on the quest of two math boffins for the perfect way to slice a pizza. It's an interesting and in-depth article; 'The problem that bothered them was this. Suppose the harried waiter cuts the pizza off-center, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-center cuts mean the slices will not all be the same size, so if two people take turns to take neighboring slices, will they get equal shares by the time they have gone right round the pizza — and if not, who will get more?' This is useful, of course, if you're familiar with the concept of 'sharing' a pizza."

What To Expect From Apple's Rumored MacPad 213

Posted by CmdrTaco on Monday July 13, 2009 @08:48AM from the speculation-is-fun dept.

Jeff writes "I decided to review the specifications of recent e-readers and mobile devices as well as the ongoing Apple rumor mill to chart out the most likely features, innovations and configuration we can expect from Apple's long awaited Newton successor/Mac Tablet which I'll call the MacPad. The MacPad will arrive in fall '09 or Jan '10, with a 10" diagonal color display, a $599 price point with a Verizon data plan, a stylus, note taking application and handwriting recognition and an e-bookstore for iTunes. Apple's biggest challenge will be convincing its huge installed base of iPhone owners that they need a MacPad too. Past failed Newtonian predictions by others are available on Slashdot and the likelihood that any of this is right can be gauged by earlier Confucian gems such as Haskin warns that Apple may be setting itself up for a failure with the iPhone."

Submission + - Surprising reasons why EDGE can outperform 3G

Submitted by goombah99 on Monday October 15, 2007 @02:50PM

goombah99 writes: Blackfriars's communications has an interesting discourse on why the practical difference between 3G and EDGE cellphone data networks is less than it appears to be based on a naive bandwidth metric. Their argument is that user experience of TCP/HTML is much more impacted by latency, error-rates, and processor speed than bandwidth, and Edge had the edge on all three. Additionally, EDGE may consume orders of magnitude less power, which may partly explain how the thin iphones big battery life allows it to get along without having the user lugging a second battery.
