Wild guess: someone heard the word "Heisenbug" once and couldn't recall it, so asked StackExchange for help? EDIT: it even is mentioned in the comments.

- nosianu 7y ago(German here) "Heisenbug" is not the same at all! That's... about a bug (also see https://en.wikipedia.org/wiki/Heisenbug https://en.wikipedia.org/wiki/Heisenbug -- although I dislike being a "definition fanatic", here it's even in the word itself - "...-bug") "Heisenbug" does not have anything to do with the main feature ("Vorführ-Effekt" -- meaning "demonstration[/presentation] effect"), that you try to present it to others. It also occurs when you debug it on your own and even when you are not looking, unlike the Vorführeffekt which specifically happens when you demonstrate something (not a bug, but can be a bug - anything). If it is something that is supposed to work but it does not when you demonstrate it, there does not have to be a "bug" somewhere for this effect! It can just be that the power goes out city-wide. Which does not have to be due to a bug in that outside system either, you could just have overlooked scheduled maintenance. Or somebody trips over the power cable. The reason for the failure can be completely external and outside the thing you are trying to present. Vorführeffekt is much more general. The other comments have quite a few good examples and explanations.
