Tips and Tricks for Tweaking and Using Ruby and Rails...
summary
A free ad‑supported Ruby on Rails app runs as a Linux cloud backend and as a local Windows install in customer sites, with 450,000+ installations managing 20 million devices and 13 million users; updates use a hybrid heartbeat that hot‑swaps gems via a custom Mongrel handler for minor templates and staged major upgrades. Windows Ruby is sped up by enabling MSVC optimizations and small C fixes for a 25–40% Ruby speedup. SQLite writers use a tweaked deadlock‑retry and priority signaling for UI over scanner writes, and the network scanner is parallelized and moved into a C extension, reduced scan time from 25s to 2s.
