[refreshen of the blood.]
You mentioned the title of Donald Knuth's magnum opus Art of Programming in the context of discussion that fringes on whether programing is science or art. I'm quite pissed off at work at the moment, so let me take the time to give some guide on this matter to the daily programers.
At the bottom rung of programers, there's no question about whether programing is science or art. Because monkey coders could not care less. These folks ain't be reading this post, for they hardly will have heard of lisp.
This leaves us with elite programers who have a smattering of interests on cogitation and philosophical conundrums. So, is programing a science or art?
final say here: Is Programing Art or Science
