but maintenance gets hard when they aren't evocative. Not so. Did you ever see music annotated with: "This_is_the_second_demi_semi_quavar_in_the_third_bar_of_fifth_stanza" (*). Or a resistor on a circuit diagram annotated: "This_is_the_470_ohmm_resistor_that_impedance_matches_the_output_of_the_third_stage_amplification_to_the_fourth_stage_feed_back_loop". (**) (*)I've no idea if that makes sense, but a musician would. (**)Ditto; but an electronics engineer would. Short variable names in context are just as clear to the maintanence programmer, and often more so, than long, overly descriptive ones--if the programmer has familiarised themselves with the purpose of the routine of which they are a part. And if he hasn't, he should not be maintaining the code. Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
