Don't be so hasty judging merit of questions, other people need different things than you do. | |

| Mar 5, 2019 at 22:10 | comment | added | Jörg W Mittag | @BlueRaja-DannyPflughoeft: Actually, for "name-that-thing"-questions it does, because those questions are off-topic for being opinion-based if there is no answer (everybody has their own opinion what the name should be), off-topic for being a list question (too broad) if there are multiple answers, and on-topic IFF there is a single, canonical, correct, objective, agreed-upon term. That makes these questions very hard on the asker because in order to know whether the question is on-topic, you already need to know (the existence of) the answer. This was discussed on Software Engineering Meta a couple of times. | |

If you feel differently, cast your downvote and/or complain on Meta. Based on the upvotes this Q/A has, the community will disagree with you on Meta. | |
| Mar 5, 2019 at 1:39 | comment | added | Rufus | @dotancohen This has been a term that I repeatedly forget and found somewhat difficult to google (googling the title of this question doesn't turn up the desired result). Hence I made use of the "Answer your own question" function to provide some sort of "note to future self" in case I find the need to use this term again. Just thought I'd share it | |

| Mar 4, 2019 at 17:28 | comment | added | Robert Harvey | @dotancohen: To be honest, the top-voted answer doesn't have much merit. It would be better if the answer included examples illustrating why idempotence is important. This isn't Jeopardy. | |

| Mar 4, 2019 at 16:47 | comment | added | ChrisW | @dotancohen That's a question to post, a topic to discuss, on Meta. | |
| Mar 4, 2019 at 16:37 | comment | added | dotancohen | @glglgl: I agree, for questions with merit. What merit has this question? I'm seriously concerned that we'll start getting every CS 101 question asked and immediately answered by the OP, every single CS term asked and immediately defined by the OP, and every basic algorithm's pros and cons questioned then immediately answered by the OP (not necessarily this OP). Is that the site that we want softwareengineering.SE to be? | |

| Mar 4, 2019 at 16:29 | comment | added | dotancohen | Why was this question asked, if the OP knew the answer at the time of asking? Is there any reason other than rep/points/karma building? | |
| Mar 4, 2019 at 16:11 | comment | added | Bergi | @RobertHarvey By that argument, func2 would be idempotent as well - it takes no input and produces the same void output no matter how often it is called. No, that's not helpful. In imperative programs, we need to consider the environment state (that the function is closing over and which it might mutate) as in- and output (in addition to arguments and return values) | |
| Mar 4, 2019 at 16:11 | comment | added | Taemyr | @WalterMitty Init() functions can easily have no arguments, and if well designed are idempotent. | |
| Mar 4, 2019 at 15:34 | comment | added | Robert Harvey | @WalterMitty: The same way a function with arguments is idempotent; it produces the same result, given the same input (which, in this case, is no input). I do hear what you are saying, though; it's clearly less useful with parameterless functions, but the examples do clearly illustrate the concept. | |

| Mar 4, 2019 at 8:38 | comment | added | Jörg W Mittag | To the close voter(s): while it is true that 99.999% (rough estimate) of all "name-that-thing" questions are off-topic because they don't have a single, correct, unambiguous, objective answer and the naming is purely subjective and opinion-based, this one does have a single, correct, unambiguous, objective answer, which was given by the OP himself. | |
