P.O.D. /P·O·D/. [rare; sometimes 'POD' without the periods] Acronym for 'Piece Of Data' or 'Plain Old Data' (as opposed to a code section, or a section containing mixed code and data). The latter expansion was in use by the C++ standards committee, for which it indicated a struct or class which only contains data (as in C), distinguished from one which has a constructor and member functions. There are things which you can do with a P.O.D. which you can't with a more general class.
packet over air . [common among backbone ISPs] The protocol notionally being used by Internet data attempting to traverse a physical gap or break in the network, such as might be caused by a {fiber-seeking backhoe}. "I see why you're dropping packets. You seem to have a packet over air problem."
padded cell n. Where you put {luser}s so they can't hurt anything. A program that limits a luser to a carefully restricted subset of the capabilities of the host system (for example, the rsh(1) utility on USG Unix). Note that this is different from an {iron box} because it is overt and not aimed at enforcing security so much as protecting others (and the luser) from the consequences of the luser's boundless naivete (see {naive}). Also padded cell environment.
page in v. [MIT] 1. To become aware of one's surroundings again after having paged out (see {page out}). Usually confined to the sarcastic comment: "Eric pages in, {film at 11}!" 2. Syn. swap in; see {swap}.
page out vi. [MIT] 1. To become unaware of one's surroundings temporarily, due to daydreaming or preoccupation. "Can you repeat that? I paged out for a minute." See {page in}. Compare {glitch}, {thinko}. 2. Syn. swap out; see {swap}.
