talking with my wife about failure modes and robust design, and had the occasion to use the unique phrase "any failure mode that results in your bra being advertised with a picture of Hitler's face is not a good one"
@q@glauca.space an online clothing shop decided they needed a placeholder image as a default for all unlisted sales items, and someone had the thought "hmm we should make it something that really makes it obvious we didn't set an image yet, so nobody can ever forget to apply an image", and thus the default foolishly became a picture of Hitler's face, forgetting the golden rule that all processes will eventually fail at some point.
