SIG
/sig/, n.
(also common as a prefix in combining forms) A Special Interest Group,
in one of several technical areas, sponsored by the Association for
Computing Machinery; well-known ones include SIGPLAN (the Special
Interest Group on Programming Languages), SIGARCH (the Special
Interest Group for Computer Architecture) and SIGGRAPH (the Special
Interest Group for Computer Graphics). Hackers, not surprisingly, like
to overextend this naming convention to less formal associations like
SIGBEER (at ACM conferences) and SIGFOOD (at University of Illinois).
signature
sig
1. A set of function symbols with {arities}.
2. <messaging> (Or sig) A few lines of information about the
sender of an {electronic mail} message or {news} {posting}.
Most {Unix} mail and news software will {automagically} append
a signature from a file called .signature in the user's {home
directory} to outgoing mail and news.
A signature should give your real name and your {e-mail
address} since, though these appear in the {headers} of your
messages, they may be {munged} by intervening software. It is
currently (1994) hip to include the {URL} of your {home page}
on the {World-Wide Web} in your sig.
The composition of one's sig can be quite an art form,
including an {ASCII} logo or one's choice of witty sayings
(see {sig quote}, {fool file}). However, large sigs are a
waste of {bandwidth}, and it has been observed that the size
of one's sig block is usually inversely proportional to one's
prestige on the net.
See also {doubled sig}, {sig virus}.
2. <programming> A concept very similar to {abstract base
classes} except that they have their own {hierarchy} and can
be applied to compiled {classes}. Signatures provide a means
of separating {subtyping} and {inheritance}. They are
implemented in {C++} as patches to {GCC} 2.5.2 by Gerald
Baumgartner <[email protected]>.
