Three terms that seem to cause confusion: Idempotence, Hysteresis and Deterministic. The subject came up during my webcast on the Five Kinds of Python Functions. We can use all three terms to describe a function. Two of them are relevant to common design questions in software. The third is a …

Of course, I've got too many slides. 58 slides for a 60 minute presentation. That's really about 2 hours of material. Unless people have questions, then it's a half-day seminar.

Seriously.

I think I've gone waaaay too far on this. But …
