Talk:Idempotence (computer science)

From Wikipedia, the free encyclopedia

> Elevator call buttons are also idempotent, though some people think they are not.

Should that be clarified? That applies only until the time the elevator arrives to service the call request. (Pushing the button again before the elevator arrives has one effect (none); pushing the button again after the elevator arrives and commits to leave has a different effect (a second arrival).)

Well, neither button push really affected the other. Maybe the definition of the word should be clarified? --67.172.99.160 03:04, 30 October 2005 (UTC)

Haha that's funny, it sounds kind of like a joke about people who are impatient waiting for the elevator to arrive and keep pressing the button over and over. 66.92.144.74 22:35, 22 December 2005 (UTC)

are you going to attribute that quote to its rightful owner, Donald Knuth?
