Doom is a series of first-person shootervideo games developed by id Software. The series focuses on the exploits of an unnamed space marine operating under the auspices of Union Aerospace Corporation (UAC), who fights hordes of demons and the undead in order to survive.
Doom is considered to be one of the pioneering first-person shooter games, introducing to IBM-compatible computers features such as 3D graphics, third dimension spatiality, networked multiplayer gameplay, and support for player-created modifications with the Doom WAD format. Since the release of Doom in 1993, the series has spawned numerous sequels, expansion packs, and a film.
Since its debut, over 10 million copies of games in the Doom series have been sold.
Clean is the second full-length studio album from industrial band Deitiphobia, released in 1994 by Myx Records. It is the earliest Deitiphobia album not to feature Brent Stackhouse, who left in 1992, and was also the band's debut for the Myx label. The album features Sheri Shaw, who remained with Deitiphobia until it dissolved in 2001, and Michael Knott, who produced Fear of the Digital Remix and was also the founder of the band's previous record label, Blonde Vinyl.
Clean's method for dealing with mutable state and I/O is done through a uniqueness typing system, in contrast to Haskell's use of monads. The compiler takes advantage of the uniqueness type system to generate more efficient code, because it knows that anything with a uniqueness type can only be used once. Therefore, a unique value can be changed in place.
