Why was "tantrum" trending last week?
ornamental stone, 1721, earlier iada (1590s), from French le jade, error for earlier l'ejade, from Spanish piedra de (la) ijada (1560s), "stone of colic, pain in the side" (jade was thought to cure this), from Vulgar Latin *iliata, from Latin ilia (plural) "flanks, kidney area" (see ileum).
"worn-out horse," late 14c., "cart horse," of uncertain origin. Barnhart suggests a variant of yaid, yald "whore," literally "mare," from a Scandinavian source akin to Old Norse jalda "mare," from Finno-Ugric (cf. Mordvin al'd'a "mare"). But OED finds the assumption of a Scandinavian connection "without reason." As a term of abuse for a woman, it dates from 1550s.
1. U Washington, late 80's. A strongly-typed language, object-oriented but without classes. For type research. The compiler output is Smalltalk. [Submitter claimed that Jade has exactly one user!]
2. Implicit coarse-grained concurrency. The constructs 'with', 'withonly' and 'without' create tasks with specified side effects to shared data objects. Implemented as a C preprocessor. "Coarse-Grain Parallel Programming in Jade", M.S. Lam et al, SIGPLAN Notices 26(7):94-105 (Jul 1991).
