Aunc.1687 net.unix-wizards utzoo!decvax!duke!unc!wm Mon Jan 11 18:07:46 1982 Human Factors (watmath.1402 followup) Richard Bartels made a very good point when he pointed out the differences between (a)'s and (b)'s (hackers vs. naive users). Someone said something about not minding having to have a manual next to them while they computed, since a mechanic working on a car wouldn't mind having a manual with them while they worked. That person is definitely an (a). Compare that to a person trying to DRIVE a car (more comparable to a (b)). What would they think if they had to have a manual along in order to drive?
