One
of the most artful door-opening tricks, commonly
attributed to Greenblatt, involved bending a stiff wire
into a cane and attaching a loop of tape to the long
end. Sliding the wire under the door, a hacker could
twist and rotate the wire so that the long end touched
the door knob. Provided the adhesive on the tape held,
a hacker could open the doorknob with a few sharp twists.
When Stallman tried the trick, he found it good but
wanting in a few places. Getting the tape to stick
wasn't always easy, and twisting the wire in a way that
turned the doorknob was similarly difficult. Stallman
remembered that the hallway ceiling possessed tiles
that could be slid away. Some hackers, in fact, had
used the false ceiling as a way to get around locked
doors, an approach that generally covered the
perpetrator in fiberglass but got the job done.
Stallman considered an alternative approach. What if,
instead of slipping a wire under the door, a hacker
slid away one of the panels and stood over the door jamb?
Stallman took it upon himself to try it out.
