Rails 3.1 Whirlwind Tour

on YouTube ↗38m

" summary

Rails 3.1 actually shows what changes do: asset pipeline concatenates and minifies JS/CSS via Sprockets (requires a server JS runtime like therubyracer on Heroku), HTTP streaming can flush the head early but needs a streaming server like Unicorn and breaks some Rack middleware, reversible migrations replace up/down with change, mountable engines include routes and assets, identity map is available but off by default, prepared statements speed SQL Server but hurt MySQL, and has_secure_password uses bcrypt and user.authenticate.
