Anti-Patterns in the Wild

on YouTube ↗48m

" summary

Concrete findings, tools and outcomes: an Erlang codebase of 183k lines of Erlang across 531 modules (plus 71k header lines and 7k C) yields recurring anti‑patterns like shifting state, giant case trees and mysterious APIs. Remedies include a homebrew state monad, a quickcheck‑style refactoring validator with MEK mocking that compares pre/post behavior, use of Dialyzer, Elvis and Wrangler (with caution), and enforced code reviews; a 214‑line monster function becomes three focused functions, reducing risk while keeping behavior.
