RUBY: WRITE ONCE, RUN ANYWHERE
summary
Claims Ruby remains viable and shows cross‑platform value by sharing domain code across browser, server and mobile. Uses Opal Ruby-to-JS to run Ruby in the browser, RubyMotion static compiler to build iOS/OS X apps, Rails as backend and a shared gem (a turn-based gem) containing game rules. Implements interactors/adapters pattern so domain objects validate moves and adapters handle REST or DB persistence. Demo is a working tic‑tac‑toe multiplayer platform with Opal client, iOS client and Rails server all reusing the same core.
