sage,any species of the large genus Salvia, aromatic herbs or shrubs of the family Labiatae (mintmint,

The dried leaves are used as seasoning, especially in dressings for meat and poultry and also in sage cheese; sage tea, once popular as a beverage, has also been used as a domestic remedy for colds and other ailments and as a hair rinse. The oil is used in medicinals and flavorings and sometimes in perfumery. Prized since ancient times, common sage was thought to prolong life and to increase wisdom by strengthening the memory—whence the name.
The ornamental sages are often popularly called salvia. Of these the scarlet sage (S. splendens), native to Brazil, is best known. Clary (S. sclarea), native from the Mediterranean region to Iran, is a biennial sage whose seeds were once used to "clear the eye"; it has bluish or pinkish flowers, and its oil is sometimes used similarly to that of the common sage.
The seeds of some species of W North America, e.g., the thistle sage (S. carduacea) of California, were used by Native Americans for a flour and a beverage. Another species is S. carnosa, the purple sage of the western deserts. S. divinorum, native to S Mexico and known as diviner's sage or magic mint, has psychoactive properties and is used as a hallucinogenic drug. Most sages are good honey plants.

SAGE(1) A technical special interest group. See USENIX.
(2) (Scalable, Automated, Guided Execution) A white box test that generates test data for each unique control path in the program. Contrast with "fuzz testing," which is a black box technique that generates random input without any knowledge of the program's logic. See white box testing.
(3) (Semi-Automatic Ground Environment) The air defense system developed in the 1950s for the Cold War. SAGE combined computer systems and a sophisticated radar and communications system to track U.S. air space and send the data to 23 installations around the country. Each installation had its own computer and backup system. SAGE used CRTs, and a light pen was used to hone in on a suspicious blip on the screen.
SAGE never intercepted enemy aircraft because there were none, but the companies that built the machines, such as IBM, gained extraordinary experience that was brought to bear in later development. The SAGE computers evolved from the Whirlwind computer at MIT (see Whirlwind).
|The Whirlwind I|
|The Whirlwind was developed at MIT and became the prototype for the SAGE air defense computers. The use of CRTs and light pens were developed for the Whirlwind and became critical parts of the user interface. You could touch a blip on screen to get more information.
