POPJ /pop'J/ n.,v. [from a PDP-10 return-from-subroutine instruction] To return from a digression. By verb doubling, "Popj, popj" means roughly "Now let's see, where were we?" See RTI.
poser n. A wannabee; not hacker slang, but used among crackers, phreaks and warez d00dz. Not as negative as lamer or leech. Probably derives from a similar usage among punk-rockers and metalheads, putting down those who "talk the talk but don't walk the walk".
post v. To send a message to a mailing list or newsgroup. Distinguished in context from mail; one might ask, for example: "Are you going to post the patch or mail it to known users?"
postcardware n. A kind of shareware that borders on freeware, in that the author requests only that satisfied users send a postcard of their home town or something. (This practice, silly as it might seem, serves to remind users that they are otherwise getting something for nothing, and may also be psychologically related to real estate 'sales' in which $1 changes hands just to keep the transaction from being a gift.)
posting n. Noun corresp. to v. post (but note that post can be nouned). Distinguished from a 'letter' or ordinary email message by the fact that it is broadcast rather than point-to-point. It is not clear whether messages sent to a small mailing list are postings or email; perhaps the best dividing line is that if you don't know the names of all the potential recipients, it is a posting.
postmaster n. The email contact and maintenance person at a site connected to the Internet or UUCPNET. Often, but not always, the same as the admin. The Internet standard for electronic mail (RFC-822) requires each machine to have a 'postmaster' address; usually it is aliased to this person.
PostScript n. A Page Description Language (PDL), based on work originally done by John Gaffney at Evans and Sutherland in 1976, evolving through 'JaM' ('John and Martin', Martin Newell) at XEROX PARC, and finally implemented in its current form by John Warnock et al. after he and Chuck Geschke founded Adobe Systems Incorporated in 1982. PostScript gets its leverage by using a full programming language, rather than a series of low-level escape sequences, to describe an image to be printed on a laser printer or other output device (in this it parallels EMACS, which exploited a similar insight about editing tasks). It is also noteworthy for implementing on-the fly rasterization, from Bezier curve descriptions, of high-quality fonts
