mmm..mruby, or why yet another Ruby implementation
summary
mRuby is a minimal, embeddable Ruby implementation that compiles Ruby to C or binary bytecode and ships an incremental garbage collector, no threads, no require, and a tiny footprint. A prototype demo runs on a 64KB Lego Mindstorms box and the robot actually moves. April 2012 sees a preliminary release (Japanese government sponsored). Community work includes an iOS bridge, libuv/node bindings, mod_mruby and ArangoDB use. Benchmarks show Mandelbrot runs roughly twice as fast as MRI in the demo.
