Yet another

Short description: Idiomatic qualifier used in the name of programs

"Yet another", often abbreviated ya, Ya, or YA in the prefix of an acronym or backronym, is a humorous prefix and idiomatic qualifier used in the name of a computer program or computing-related organization or event. It is a naming convention as a form of computer humour. Stephen C. Johnson established the naming convention in the late 1970s upon creating yacc (i.e. "yet another compiler-compiler"), named in humorous self-deprecation derived from its being merely one among others of its kind, and the name itself was directly inspired by Jeffrey Ullman's astonished comment ("Another compiler-compiler?!") uttered in response to Johnson's announcement.

Outside computing, but still within the realm of science and technology, the "Yet another" construct has been used, for instance, in astronomy, which has YAMOO ("Yet Another Map of Orion").
