Mental Models for Better Code
summary
Six concrete practices and their effects: assume 90% of codebases are crap so make one small improvement today (run Brakeman and RuboCop, add a test, fix docs) and you get an order‑of‑magnitude easier codebase over years; use write an outside‑in RSpec/Capybara test first to avoid rabbit holes; treat code reviews as teaching and relationship building to spread domain knowledge and improve quality; practise nemawashi — get buy‑in person‑by‑person and always frame advice with context and a falsifiable prediction.
