Rubinius @ RubyAndRails2010
This document provides an overview of Rubinius, an implementation of the Ruby programming language that uses Just-In-Time (JIT) compilation. It discusses key aspects of Rubinius including its virtual machines, garbage collectors, bytecode compilers, core library, primitives systems, JIT compilers, and use of Rubyspec for testing. It also briefly describes the compacting generational garbage collector, inline caching, call counting, and debugging and profiling capabilities. The document encourages contributing to Rubinius and shares an example commit adding POSIX safety checks to the Process module.
