([View Highlight](https://read.readwise.io/read/01j62k9r0r02pfe3gxxe0gd1wg)) - A *mandelbug* (named after [Benoît Mandelbrot](https://en.wikipedia.org/wiki/Beno%C3%AEt_Mandelbrot)'s [fractal](https://en.wikipedia.org/wiki/Mandelbrot_set)) is a bug whose causes are so complex it defies repair, or makes its behavior appear [chaotic](https://en.wikipedia.org/wiki/Chaos_theory) or even [non-deterministic](https://en.wikipedia.org/wiki/Deterministic_system).[[2]](https://en.wikipedia.org/wiki/Heisenbug#cite_note-jarman-2) The term also refers to a bug that exhibits fractal behavior (that is, [self-similarity](https://en.wikipedia.org/wiki/Self-similarity)) by revealing more bugs (the deeper a developer goes into the code to fix it the more bugs they find).
