From time to time, people come asking questions which are unsolvable, either because a) they are fundamentally impossible, or b) because there's no sufficiently advanced technology, or c) because of limitations imposed by the environment. Examples:
- reverse a hash (not "find a preimage" - class A)
- universal translator (whose translations make sense - class B)
- show an image on a website, but prevent people from copying it (class C)
The questions usually get answered with "that is not possible", possibly "but there's this approximation", and "you are probably trying to reach a slightly different goal, which is feasible"; so far, so good.
However, there are users who, upon receiving the "no can do" response, go into "paranoid PHB mode", and starts flaming, thinking that
- anything is possible, if you want it badly enough
- it's possible, but the SO users don't want to give me the Good Solution
- "I DIDN'T ASK FOR SUGGESTIONS... I JUST ASKED HOW TO PERFORM THESE TASKS" (direct quote)
If this behavior persists, the question gets flagged into oblivion (e.g. a likely fate of this question - now deleted, only visible for 10k+ users). Because the question is not visible any more, in two weeks PHB2 comes along and ... Redo from Start
I'm aware that trolls will be trolls (and that's a very different matter), but is it worth keeping a reference of unsolvable questions for honestly clueless askers? In other word, is there anything we could do with this cycle of "Can't do that -> I don't care, show me how to do that -> delete -> repeat in an infinitesimally different setting"?
