Super-geeky, super-cool application for this plug. To make a long story short, the only website which lets you look-up large N'th prime numbers (i.e., "What is the one-billionth prime number?") is http://primes.utm.edu/nthprime/index.php#nth
but it only looks up to n=10^12 (one trillion). To do it, they used a server farm to generate a map of prime numbers (there's no formula to generate prime numbers, you have to test every number to see if it's prime and count them as you go). To replicate it (and exceed their 1 trillion limitation), I decided to write code to generate prime numbers and log them as they're discovered. This code has been running for about 9 months on my SheevaPlug, with a cool web interface served directly from the plug. It's already at n=914 billion (awesome!) and once it gets to a trillion, I'll enable the form at the bottom so you can look up individual prime numbers while it keeps crunching numbers exceeding that 1 trillion limit.Amazing - a single plug computer has done with it took a server farm of 200+ computers to do!
(I'm cheating a bit - he only had 24 hours' access to the server farm, I have as long as I want - but come on! it's a plug computer!)
