Montreal 2018 sessions

Advanced Rack

English session - Beginner

A deep dive into Rack, a piece of code we all use in Ruby world, but don't always fully understand.

Confident refactors

French session - Intermediate

This talk is walk through of a simple-but-not-trivial legacy refactor example inspired by a real world code base. We will gain confidence thanks to some tools, from manually recording calls to verifying old & new code against them, to running it in a double-entry mode appropriate for staging environments, and finally with production fallback measures until we're certain the change is safe.
