For software developers only: Dodgy Coder: “Yoda Conditions”, “Pokémon Exception Handling” and other programming classics

Excerpt:
Heisenbug – a bug that disappears or alters its characteristics when an attempt is made to study it.

Higgs-Bugson – a hypothetical bug predicted to exist based on a small number of possibly related event log entries and vague anecdotal reports from users, but it is difficult (if not impossible) to reproduce on a dev machine because you don’t really know if it’s there, and if it is there what is causing it. To find these you will need to invest in a Large Hadron debugger.
