From Rails to Rack: Making Rails 3 a Better Ruby Citizen
summary
Explains concrete changes in Rails 3: adopts Rack so middleware like Rack middleware and router points at an action become first-class, lets controllers/actions be called as rack endpoints, and adds a tiny ORM-proxy strategy so non‑ActiveRecord objects respond like AR. Shows replacing inline JS with markup so front ends can emit markup not JS and describes metaprogrammed callback compilation that cuts filter overhead dramatically. Demonstrations and code-level design choices are emphasized over high-level promises.
