Dissecting Ruby with Ruby

on YouTube ↗42m

" summary

Source code navigation is literal and practical here: use bundle open to drop into library files, use Ruby introspection like method.source_location plus caller, ancestors, instance_method and method_defined to find exactly which file and line produce a URL bug, then patch locally and submit a PR. The demo shows a real Rails bug fixed by string concatenation checks, explains responsible disclosure for wicked, and surfaces small reproducible changes that actually land in upstream.
