J. Random /J rand'm/ n. [generalized from J. Random Hacker] Arbitrary; ordinary; any one; any old. 'J. Random' is often prefixed to a noun to make a name out of it. It means roughly some particular or any specific one. "Would you let J. Random Loser marry your daughter?" The most common uses are 'J. Random Hacker', 'J. Random Loser', and 'J. Random Nerd' ("Should J. Random Loser be allowed to gun down other people?"), but it can be used simply as an elaborate version of random in any sense. |

J. Random Hacker /J rand'm hak'r/ n. [MIT] A mythical figure like the Unknown Soldier; the archetypal hacker nerd. See random, Suzie COBOL. This may originally have been inspired by 'J. Fred Muggs', a show-biz chimpanzee whose name was a household word back in the early days of TMRC, and was probably influenced by 'J. Presper Eckert' (one of the coinventors of the electronic computer). |

jack in v. To log on to a machine or connect to a network or BBS, esp. for purposes of entering a virtual reality simulation such as a MUD or IRC (leaving is "jacking out"). This term derives from cyberpunk SF, in which it was used for the act of plugging an electrode set into neural sockets in order to interface the brain directly to a virtual reality. It is primarily used by MUD and IRC fans and younger hackers on BBS systems. |

JCL /J-C-L/ n. 1. IBM's supremely rude Job Control Language. JCL is the script language used to control the execution of programs in IBM's batch systems. JCL has a very fascist syntax, and some versions will, for example, barf if two spaces appear where it expects one. Most programmers confronted with JCL simply copy a working file (or card deck), changing the file names. Someone who actually understands and generates unique JCL is regarded with the mixed respect one gives to someone who memorizes the phone book. It is reported that hackers at IBM itself sometimes sing "Who's the breeder of the crud that mangles you and me? I-B-M, J-C-L, M-o-u-s-e" to the tune of the "Mickey Mouse Club" theme to express their opinion of the beast. 2. A comparative for any very rude software that a hacker is expected to use. ''That's as bad as JCL." As with COBOL, JCL is often used |
