bum 1. vt. To make highly efficient, either in time or space, often at
the expense of clarity. "I managed to bum three more instructions out of
that code." "I spent half the night bumming the interrupt code." In
1996, this term and the practice it describes are semi-obsolete. In
elder days, John McCarthy (inventor of LISP) used to compare some
efficiency-obsessed hackers among his students to "ski bums"; thus,
optimization 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. n. A small change to an algorithm,
program, or hardware device to make it more efficient. "This hardware
bum makes the jump instruction faster." Usage: now uncommon, largely
superseded by v. tune (and n. tweak, hack), though none of these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 the noun `bum' is a
rude synonym for `buttocks' and the verb `bum' for buggery.
