A Practical Taxonomy of Bugs
summary
Classifies real production failures into four reproducible types — Bohr, Schrödinger, Heisenberg, Mandel — and gives concrete fixes: reproduce locally and in tests, add focused logs, use git bisect to find regressions, profile with qcachegrind or equivalent to spot hot callers, and check system state with df -h for disk issues. Emphasizes turning instincts into rule sets, writing minimal readable fixes, adding tests for fixed states, and keeping playbooks and on‑call procedures so incidents scale without a resident hero.
