<even more OT than before>
In en_US we (almost always?) say an active entity (person, engine,
etc.) 'runs' on fuel or energy. (But intransitively, 'xx runs on'
means to talk uselessly, syn. blather.) 'work on' connotes an activity
with a target or result; in this case the hackers would be brewing
coffee, or roasting beans, or some such.
See the /jargon file/ for an entry and cultural stuff. Summary of the summary:
enthusiastic competent programmer.
(fx:elitist (fx:sniff)) You're thinking of /crackers/, I expect.
Sniff is just a sound and not an effect, even if rerecorded. And an
elitist sniff is quite hard to distinguish. A pompous delivery of the
line, however, would make (much more) sense. HTH
