Back when I maintained the Berkeley C Compiler suite I came across a few wonderful error messages including “Data potato doo-wop doo-wop” and “Lint’s little mind is blown”.
You can do that. There are also entire media platforms like MediaGoblin.
Linux had the “helpful” message “line printer on fire”… There is also the ubiquitous “this should never happen” error, absolutely clear to the user what they should do in that case.
“This should never happen” error messages are for the benefit of the programmer, not the user, because they indicate that when the programmer thought something was impossible, they were wrong. Which helps them to figure out what mistake they made, and fix it in the next version.
XKCD also has a guide to interpreting cryptic error codes.
Is that what’s called an unhandled exception in Windows? Or, at least one flavor of unhandled exception?
