:pencil and paper: n. An archaic information storage and
transmission device that works by depositing smears of graphite on
bleached wood pulp. More recent developments in paper-based
technology include improved `write-once' update devices which use
tiny rolling heads similar to mouse balls to deposit colored
pigment. All these devices require an operator skilled at
so-called `handwriting' technique. These technologies are
ubiquitous outside hackerdom, but nearly forgotten inside it. Most
hackers had terrible handwriting to begin with, and years of
keyboarding tend to have encouraged it to degrade further. Perhaps
for this reason, hackers deprecate pencil-and-paper technology and
often resist using it in any but the most trivial contexts. See
also {Appendix B}.
