That sequence is in the database as http://oeis.org/A047778 since at least 1999. Funny, just one month ago, Neil Sloan asked "the smallest prime in this sequence is 485398038695407. What is the full subsequence of primes?" For the moment, the first is also the only prime known in this sequence.

...It's sad that they always aim at the lowest energy consumer in my household: my puny 1 W phone

Wouldn't the purpose be to be able to power your phone while you're far away from a convenient outlet or don't have your adapter handy? Some people do travel, go hiking, walk, enjoy live, ...

Multiplayer Mobile AR Gaming With No Dedicated Server 14

Posted by Soulskill on Saturday February 20, 2010 @05:14AM from the pocket-server dept.

MIT's Technology Review discusses a new augmented-reality game for Android phones called Photoshoot, which allows multiplayer without the need for an additional server. Quoting: "Multiplayer games on mobile devices like phones usually require remote servers for communication between devices and game hosting, says Roelof Kemp, a computer scientist at Vrije Universiteit, in Amsterdam, the Netherlands, who codeveloped the game. But the game allows phones to communicate without the cost and added complexity of maintaining this additional infrastructure, he says. 'We hope it's going to open the door for new and interesting distributed computing applications,' says Kemp. The game uses a computing middleware system, called Ibis, originally developed for high-performance, distributed computing tasks, such as image processing or astrophysics research, but which Kemp and colleagues have adapted to run on Android phones. 'It allows each phone to run a lightweight communication server,' says Kemp. The devices can communicate directly with the game, which is hosted on both handsets, using a 3G connection or Wi-Fi."

How To Play HD Video On a Netbook 205

Barence writes with some news to interest those with netbooks running Windows: "Netbooks aren't famed for their high-definition video playing prowess, but if you've got about $10 and a few minutes going spare, there is a way to enjoy high-definition trailers and videos on your Atom-powered portable. You need three things: a copy of Media Player Classic Home Cinema, CoreCodec's CoreAVC codec, and some HD videos encoded in AVC or h.264 formats. This blog takes you through the process."

Cornell Grad Students Go Ballooning (Again) 58

Posted by timothy on Sunday April 19, 2009 @07:16PM from the ithaca-is-gorges dept.

ballooner writes "A group of Cornell University graduate students are attempting to break the Amateur Radio Ballooning duration record this weekend. The project is a continuation from last year when some other Cornell grad students broke the altitude record. The progress of the team can be tracked via their Twitter feed or by monitoring their APRS beacons. For all the HAMs out there, downlinks are available on a 30m wavelength, too."
