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)
