Numbers Station


#1

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:

This one is awesome.


#3

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.


#4

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:


#6

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.

Holy crap, you guys:

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.
