Keynote: Ruby Today, Ruby Forever
summary
Ruby adoption is growing from about 1–2 million developers toward Gartner’s 4 million by 2013, with conferences drawing 850 at RubyConf, 1,800 at RailsConf and 2,000+ at RubyKaigi. The problem space is big data and multi‑core CPUs — 2.5 exabytes per day and projections of 128‑core machines by 2018 — so performance matters. Practical paths shown are JRuby on JVM for parallelism and Java interop, Rubinius for a Ruby‑centric VM, Maglev for distributed object storage, and invoke dynamic giving 3–10x numeric speedups.
