Preludio

L'ultima volta che ho provato Ruby è stato nell'aprile del 2005. Avevo sviluppato un paio di progetti di test in RubyOnRails, che allora era già produttivo. Ruby era affascinante, ma la libreria base mi sembrava ancora in stato embrionale e lo abbandonai. RubyOnRails non mi è mai sembrato avesse un vantaggio competitivo rispetto a framwork come CakePHP o Python Django.
