Mostly really good, but I have a problem with this one: > 67. Think of all the psychic energy expended in seeking a fundamental distinction between “algorithm” and “program”. I mean... it's semantics but I feel like taking the bait here. I have a weird concept of fun. I've always understood it as a program takes external input and/or gives external output (like keyboard presses, display to screen, write to disk, etc) whereas an algorithm is self contained and can run on any turing machine regardless of capabilities. Basically "Side Effects", but I avoided using that phrase because input isn't clearly a side effect, but if your semantics don't require no side effects for an algorithm, then yeah a program is functionally equivalent to an algorithm. Mostly semantics don't capital-M Matter, but can be important to clarify meanings. Depending on what project/team I'm working on I can have completely incompatible definitions of the same word in the same day.
