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)
