mruby: a Packaging Story Filled with Freedom
summary
Explains how mruby actually produces self-contained CLI binaries: compiles Ruby to mrb bytecode, wraps in C and cross-compiles via Docker so one host builds Linux, OS X and Windows executables. Claims real speed wins — a simple app boots ~3 ms boot vs ~40 ms on MRI — and tiny outputs (example 421k OSX binary). Notes tradeoffs: no require and a trimmed Ruby core (no built-in IO, threads or many gems) and tooling for mrb gems, testing and release automation.
