I have been programming since like 1985 and I just realized this minute that a "corner case" is, like, where an edge case hits another edge case and gets even weirder. I've been using "edge case" and "corner case" as synonyms without ever thinking about it.
@zarfeblong holy shit
@zarfeblong me too, mind = blown
now if there's a camel in the corner..
@zarfeblong The analogy with geometry goes farther, possibly without becoming completely silly. We can think about edge cases as surfaces (loosely speaking) in some high dimensional program state space. In the arrangement of these surfaces there is then "faces" of varying dimension, with the corner cases have as many edge cases intersecting as state variables.
@zarfeblong 🤯 omg I never realized
@zarfeblong I want to believe these terms came from early robotics research
