Why I like JRuby (and you should too)
summary
Argues that JRUby unlocks Java libraries (examples: calling Stanford NLP and JavaMail directly), that a real project—an open‑source JRuby on Rails app with 10,000 tests—runs on the JVM, and that deployment uses Warbler war file packaging. Claims measurable gains: JIT improves throughput over time and real threads cut server costs versus MRI, while practical costs include incompatible C‑extension gems, long app startup (Spork issues), and nontrivial porting work.
