RTFB: /R·T·F·B/, imp. [Unix] Abbreviation for ‘Read The Fucking Binary’. Used
when neither documentation nor source for the problem at hand exists, and
the only thing to do is use some debugger or monitor and directly analyze
the assembler or even the machine code. “No source for the buggy
port driver? Aaargh! I hate proprietary operating
systems. Time to RTFB.”
Of the various RTF? forms, ‘RTFB’ is the least pejorative
against anyone asking a question for which RTFB is the answer; the anger
here is directed at the absence of both source and
adequate documentation.
