Gamelan is a good-enough soft real-time event scheduler, written in Ruby, especially for music applications.

A simple LRU-cache based on a hash and priority queue

Ruck uses continuations and a simple scheduler to ensure "shreds" (Ruck threads) are woken at precisely the right time according to its virtual clock. Schedulers can map virtual time to samples in a WAV file, real time, time in a MIDI file, or anything else by overri...

A graph implementation supporting Dijkstra's shortest path algorithm

This gem allow you to encode and decode a text using the Huffman encoding compression algorithm. It can also generate and visualize the huffman tree as a png file.

Mendel breeds the best combinations of N lists without building all possible combinations.

Queued RPC client and server. Works as normal RPC server, but through queue interface, so allows highly scalable, distributed and asynchronous remote API implementation and fast data processing. It's based on EventMachine and typically on Beanstalk, so it's fast and thread safe.

Unifies many queue implementations under the single interface. Includes both single queue libraries and multiple queue libraries.
