"Older Brother" in Nepali. A general form of address for any male older than the speaker, or in a position of authority. Pronounced DAO.

DAO is an acronym for Disk At Once, a method of recording to a CD-R/RW. When recording tracks, such as when you record audio CDs, the laser is turned off between the songs, creating a two-second gap. If you have a live CD, it gets annoying to have the audience making lots of noise, then two seconds of silence, then the audience making noise again. DAO records the entire CD in one shot, never turning off the laser.

DAO is short for double action only, a type of firearm mechanism which can only be fired from an uncocked state.

Hence all trigger pulls are in double action.
