What do you name variables with no meaning

_

$null

test, asd, asdasd, asd123, tmp

Foo, bar, baz. if I need more than those it's time to walk away and have a drink.

Why do you have variables with no meaning?

$mylife

@endre86 That was my first thought, but then I realised that I do it when debugging sometimes.

@lreading But I bet they still mean something. A response from something, a partial calculation, etc. If it's just for debugging, sure you don't want to use time finding a suiting name. But sometimes I find that the debugging variable is nice to keep in the code, because there happened something that was not transparent.

Every variable has a meaning

Test

I use foo, bar, baz.
I have often seen data as a placeholder or simply placeholder :p

I don't declare variables without meaning and if you do you should be ashamed.

@oskaremil I bet your shit doesn't stink either, and you've never had trouble debugging something.

@lreading Assumption: incorrect

thing, shit, test, one, two.. But those are just some placeholders (until you find the meaning).. all variables have meaning.. if they don't, they don't belong.

blah

All variables should have meaning.
If you are talking about iterators, something like i.
If you're talking about callback function arguments that never get used, I still name them according to what they represent, even if they don't ever get used.

In my country (Poland), the most common is "dupa", as a temporary variable for everything. But you'd better never forget to remove it before outage or presentation.
