bum
1. To make highly efficient, either in time or space, often at the expense of cl arity. "I managed to bum three more instructions out of that code." "I spent half the night bumming the interrupt code." In elder days, John McCarthy (inventor of Lisp) used to comp are some efficiency-obsessed hackers among his students to "ski bums" thus, optimisation became "program bumming", and eventually just "bumming". 2. To squeeze out excess to remove something in order to improve whatever it was removed from (without changing function this distinguishes the process from a featurectomy). 3. A small change to an algorithm, program, or h ardw are device to make it more efficient. "This h ardw are bum makes the jump instruction faster." Usage: now uncommon, l argely superseded by v. tune (and tweak, hack), though none of these exactly capture sense 2. All these uses are r are in Commonwealth hackish, because in the p arent dialects of English "bum" is a rude synonym for "buttocks".
