Numbers Station

All the work is from @nemomen. I wrote a simple API and stood up a small server. I think they are mesmerizing.

I’d like to figure out ways of turning them into textures or patterns. Lots of .js work ahead :smiley:

I’m still working at putting primepal on github. Here’s a video of it finding all 33 digit long palindromic primes with two digits in the number.

Oh, here is the tool calculating smoothly undulating palindromic primes up to 1555 digits.

After 1500 digits or so the speed drops by a good bit so it’s less interesting to watch the number stream. At 10,000 digits the factoring takes a minute, while the candidates are rarely primes.

the superbowl started, and we are calculating primes and writing APIs. who’s gonna inherit the earth!? WE are gonna inherit the earth :smiley:

While it’s not the nicest way to post it (not a proper project with Makefile/configure/dependency resolution/etc), here’s the program in its prime:

With GMP installed it should compile on OS X/Linux with minimal pain. God only knows what Windows would do.

I just added in some optimizations yesterday to precalculate some powers of ten that gave a 10% speed bump.

2578 1s with a 6 in the middle is a probable prime.

And now, back to your normal numbers station programming.

linking to a specific prime is now supported.
searching for a prime is now supported.

if you want to go directly to a prime simple go to http://numberwang.ddns.net/number.station#[sha1_of_the_prime]

programittically you can access the search head by issuing http://numberwang.ddns.net/search.station?s=[prime_or_prime_fragment]
this will return a sha1 of that prime or nothing. if you get a number, that is the latest prime that matches.
