The New Hacker's Dictionary

2. v. [common, Toronto area] To instantly fetch a file (other than a mail attachment) whether by FTP or IRC file req or any other method. Seems to be a holdover from the early 1990s when Toronto had a very active BBS and warez scene.

leech mode // n.

[warez d00dz] "Leech mode" or "leech access" or (simply "leech" as in "You get leech") is the access mode on a FTP site where one can download as many files as one wants, without having to upload. Leech mode is often promised on banner sites, but rarely obtained. See ratio site, banner site.

legal // adj.

Loosely used to mean 'in accordance with all the relevant rules', esp. in connection with some set of constraints defined by software. "The older =+ alternate for += is no longer legal syntax in ANSI C." "This parser processes each line of legal input the moment it sees the trailing linefeed." Hackers often model their work as a sort of game played with the environment in which the objective is to maneuver through the thicket of 'natural laws' to achieve a desired objective. Their use of 'legal' is flavored as much by this game-playing sense as by the more conventional one having to do with courts and lawyers. Compare language lawyer, legalese.

legalese // n.

Dense, pedantic verbiage in a language description, product specification, or interface standard; text that seems designed to obfuscate and requires a language lawyer to parse it. Though hackers are not afraid of high information density and complexity in language (indeed, they rather enjoy both), they share a deep and abiding loathing for legalese; they associate it with deception, suits, and situations in which hackers generally get the short end of the stick.

LER /L-E-R/ n.

1. [TMRC, from 'Light-Emitting Diode'] A light-emitting resistor (that is, one in the process of burning up). Ohm's law was broken. See also SED.

2. An incandescent light bulb (the filament emits light because it's resistively heated).

LERP /lerp/ vi., n.

Quasi-acronym for Linear Interpolation, used as a verb or noun for the operation. "Bresenham's algorithm lerps incrementally between the two endpoints of the line."
