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])
