bum
1. To make highly efficient, either in time or space, often at the expense of clarity. "I mana GEd 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 compare 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 chan GE to an algorithm, program, or hardware device to make it more efficient. "This hardware bum makes the jump instruction faster." Usa GE: now uncommon, lar GEly superseded by v. tune (and tweak, hack), though none of these exactly capture sense 2. All these uses are rare in Commonwealth hackish, because in the parent dialects of English "bum" is a rude synonym for "buttocks".
