:sysape: /sys'ayp/ /n./ A rather derogatory term for a computer operator; a play on {sysop} common at sites that use the banana hierarchy of problem complexity (see {one-banana problem}).
:sysop: /sis'op/ /n./ [esp. in the BBS world] The operator (and usually the owner) of a bulletin-board system. A common neophyte mistake on {FidoNet} is to address a message to `sysop' in an international {echo}, thus sending it to hundreds of sysops around the world.
:system: /n./ 1. The supervisor program or OS on a computer. 2. The entire computer system, including input/output devices, the supervisor program or OS, and possibly other software. 3. Any large-scale program. 4. Any method or algorithm. 5. `System hacker': one who hacks the system (in senses 1 and 2 only; for sense 3 one mentions the particular program: e.g., `LISP hacker')
:systems jock: /n./ See {jock}, sense 2.
:system mangler: /n./ Humorous synonym for `system manager', poss. from the fact that one major IBM OS had a {root} account called SYSMANGR. Refers specifically to a systems programmer in charge of administration, software maintenance, and updates at some site. Unlike {admin}, this term emphasizes the technical end of the skills involved.
:SysVile: /sis-vi:l'/ /n./ See {Missed'em-five}.
= T = =====
:T: /T/ 1. [from LISP terminology for `true'] Yes. Used in reply to a question (particularly one asked using {The `-P' convention}). In LISP, the constant T means `true', among other things. Some Lisp hackers use `T' and `NIL' instead of `Yes' and `No' almost reflexively. This sometimes causes misunderstandings. When a waiter or flight attendant asks whether a hacker wants coffee, he may absently respond `T', meaning that he wants coffee; but of course he will be brought a cup of tea instead. Fortunately, most hackers (particularly those who frequent Chinese restaurants) like tea at least as well as coffee — so it is not that big a problem. 2. See {time T} (also {since time T equals minus infinity}). 3. [techspeak] In transaction-processing circles, an abbreviation for the noun `transaction'. 4. [Purdue] Alternate spelling of {tee}. 5. A dialect of {LISP} developed at Yale. (There is an intended allusion to NIL, "New Implementation of Lisp", another dialect of Lisp developed for the {VAX})
:tail recursion: /n./ If you aren't sick of it already, see {tail recursion}.
:talk mode: /n./ A feature supported by Unix, ITS, and some other OSes that allows two or more logged-in users to set up a real-time on-line conversation. It combines the immediacy of talking with all the precision (and verbosity) that written language entails. It is difficult to communicate inflection, though conventions have arisen for some of these (see the section on writing style in the Prependices for details).
