Lightning Talks
summary
A rapid-fire set of concrete demos and lessons: Ruby multiprocessing using fork, Signal.trap and IO.pipe with the claim that Ruby 2.1's copy‑on‑write makes forking fast; a Postgres materialized view used for full‑table indexing and a gold‑master test that diffs every row (later replaced by Sunspot/Elasticsearch); Zsh escape hacks for reusing and quoting previous arguments; a Rails Girls Summer of Code team that ships a BrowserCMS–Spree integration (released Oct 1) and notes dependency fights with Paperclip/rails.
