Add Ruby port #10

Closed zaeleus closed 10 years ago

zaeleus commented 10 years ago

I ported the original C++ implementation (with some reference to the Go implementation) to Ruby. I have not fully profiled the code to check if it's optimal.

The implementation is multithreaded, but unfortunately, MRI's GIL does not allow for thread-level parallelism. It is recommended to run on either [Rubinius][2] or [JRuby][3], which is an alternative Ruby implentation that does support real threading.

It is... not fast. :)

Good thing to test on Rubinius 2.0, now that it is released
