The Error of our Ways
summary
A tour of concrete failures: a DOS TCP/IP error and a Dutch rail site leaking Java NullPointerException show how encapsulation breaks; a trading firm loses $460M in 45 minutes after dead code repurposed after eight years and a single node misses an update; a Mars lander triggers parachute release from a bogus negative altitude (craft still 3,700 m high); an O2 outage traces to an expired certificate; many production incidents are simple missing checks and a majority reproducible by unit tests.
