Here Be Dragons
summary
A concrete postmortem of a rotten Ruby feature: a gossip app whose share by email or SMS endpoint throws 500s, calls an external TinyURL service on every request, and contains dead, misnamed code and no tests; one quick two-line patch fixes immediate failure but the author extracts and publishes an anonymized Sinatra example (CSI Ruby) to show the deeper problems. The talk quantifies decay with 62 exploitive points, demonstrates using curl and stack traces, and argues for game‑theory driven team practices (iterated Prisoner’s Dilemma) to make cooperation the rational choice.
