Comment Re:Base 10 sequences, other bases of interest? (Score 1) 189

That sequence is in the database as 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.

Submission + - Where Are All The Wireless Tablets?

fard69 writes: "When trying to get out from under the abusive relationship I have with my wireless carrier (nameless to avoid lawsuits) by using a prepaid cell plan with a phone and a tablet, I discovered that nearly no 4G tablets are available for use with prepaid phone/data cards. I live in the SF Bay Area, nominally a hotbed of the latest geek tech. So, where are these tablets? I see them reviewed in every website in geekdom, but no 4G tablets ever seem to make it to any retail outlets.
Where do SF/SJ Slashdotters get their 4G tablets?"

Multiplayer Mobile AR Gaming With No Dedicated Server 14

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

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."
