Word Origin & History

bar  (3)
"whole body of lawyers, the legal profession," 1559, a sense which derives ultimately from the railing that separated benchers from the hall in the Inns of Court. Students who had attained a certain standing were "called" to it to take part in the important exercises of the house. After c.1600, however, this was popularly assumed to mean the bar in a courtroom, which was the wooden railing marking off the area around the judge's seat, where prisoners stood for arraignment and where a barrister (q.v.) stood to plead. As the place where the business of court was done, bar in this sense had become synonymous with "court" by c.1330.

barn 
O.E. bereærn "barn," lit. "barley house," from bere "barley" (see barley) + aern "house," metathesized from *rann, *rasn (cf. O.N. rann, Goth. razn "house," O.E. rest "resting place"). Barnstorming first applied 1815 to a theatrical troupe's performances in upstate N.Y. barns (usually featuring short action pieces to suit vulgar tastes); extended 1896 to electioneering, 1928 to itinerant airplane pilots who performed stunts at fairs and races. Barn door figurative for "broad target" and "great size" since 1547.

B
1. byte.
2. A systems language written by Ken Thompson in 1970 mostly for his own use under Unix on the PDP-11. B was later improved by Kerninghan(?) and Ritchie to produce C. B was used as the systems language on Honeywell's GCOS-3.
B was, according to Ken, greatly influenced by BCPL, but the name B had nothing to do with BCPL. B was in fact a revision of an earlier language, bon, named after Ken Thompson's wife, Bonnie.
