[from LISP terminology for ‘true’] Yes. Used in
|
||
reply to a question (particularly one asked using <a href="../p-convention.html" title="The -P Convention">The -P convention</a>). 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. </p></dd><dd><p> 2. See <a href="time-T.html"><i class="glossterm">time T</i></a> (also
