:jolix: n. /johl'liks/ n.,adj. 386BSD, the freeware port of the BSD Net/2 release to the Intel i386 architecture by Bill Jolitz and friends. Used to differentiate from BSDI's port based on the same source tape, which is called BSD/386. See {BSD}.
:JR[LN]: /J-R-L/, /J-R-N/ n. The names JRL and JRN were sometimes used as example names when discussing a kind of user ID used under {{TOPS-10}} and {WAITS}; they were understood to be the initials of (fictitious) programmers named `J. Random Loser' and `J. Random Nerd' (see {J. Random}). For example, if one said "To log in, type log one comma jay are en" (that is, "log 1,JRN"), the listener would have understood that he should use his own computer ID in place of `JRN'.
:JRST: /jerst/ [based on the PDP-10 jump instruction] v.,obs. To suddenly change subjects, with no intention of returning to the previous topic. Usage: rather rare except among PDP-10 diehards, and considered silly. See also {AOS}.
:juggling eggs: vi. Keeping a lot of {state} in your head while modifying a program. "Don't bother me now, I'm juggling eggs", means that an interrupt is likely to result in the program's being scrambled. In the classic first-contact SF novel `The Mote in God's Eye', by Larry Niven and Jerry Pournelle, an alien describes a very difficult task by saying "We juggle priceless eggs in variable gravity." That is a very hackish use of language. See also {hack mode}.
:jump off into never-never land: [from J. M. Barrie's `Peter Pan'] v. Same as {branch to Fishkill}, but more common in technical cultures associated with non-IBM computers that use the term `jump' rather than `branch'. Compare {hyperspace}.
:jupiter: [IRC] vt. To kill an {IRC} {robot} or user, and then take its place by adopting its {nick} so that it cannot reconnect. Named after a particular IRC user who did this to NickServ, the robot in charge of preventing people from inadvertently using a nick claimed by another user.
= K = =====
:K: /K/ [from {kilo-}] n. A kilobyte. This is used both as a spoken word and a written suffix (like {meg} and {gig} for megabyte and gigabyte). See {{quantifiers}}.
:K&R: [Kernighan and Ritchie] n. Brian Kernighan and Dennis Ritchie's book `The C Programming Language', esp. the classic and influential first edition (Prentice-Hall 1978; ISBN 0-113-110163-3). Syn. {White Book}, {Old Testament}. See also {New Testament}.
:K-line: [IRC] v. To ban a particular person from an {IRC} server, usually for grossly bad {netiquette}. Comes from the `K' code used to accomplish this in IRC's configuration file.
