Noun · Hacker Culture

Definitions

  1. Originally a philosophical phrase, now often used to describe behavior in a machine or system that feels strangely human, mysterious, or hard to explain. In tech culture it usually appears when software acts unexpectedly enough to feel haunted.

    In plain English: A mysterious or oddly human-seeming behavior in a machine or system.

    Example: "The flaky test had real ghost in the machine energy because it failed only on Tuesdays, only in CI, and only after unrelated logging changes."
