• plaid screen n. [XEROX PARC] A `special effect' that occurs when certain kinds of memory smashes overwrite the control blocks or image memory of a bit-mapped display.
  The term "salt and pepper" may refer to a different pattern of similar origin....
• memory smash: [XEROX PARC] n. Writing through a pointer that doesn't point to what you think it does.
  This occasionally reduces your machine to a rubble of bits....
• munching squares: n. A {display hack} dating back to the PDP-1 (ca.
  1962, reportedly discovered by Jackson Wright), which employs a trivial computation (repeatedly plotting the graph Y = X XOR T for successive values of T --- see {HAKMEM} items 146--148) to produce an impressive display of moving and growing squares that devour the screen....
• blit: /blit/ vt. 1. To copy a large array of bits from one part of a computer's memory to another pa
  particularly when the memory is being used to determine what is shown on a display screen....
• memory smash n. [XEROX PARC] Writing through a pointer that doesn't point to what you think it does.
  This occasionally reduces your machine to a rubble of bits....
• virtual: [via the technical term `virtual memory', prob.
  from the term `virtual image' in optics] adj. 1....
• MOUSE Computer input device, named by some scientists at Xerox when they were pissed out of their brains.
  They also labelled the computer's display screen a Vole, but were less successful in spreading of this term....
• bitblt: /bit'blit/ n. [from {BLT}, q.v.] 1. Any of a family of closely related algorithms for moving and copying rectangles of bits between main and display memory on a bit-mapped device
  or between two areas of either main or display memory (the requirement to do the {Right Thing} in the case of overlapping source and destination rectangles is what makes BitBlt tricky)....
• dirtball: [XEROX PARC] n. A small, perhaps struggling outside
  not in the major or even the minor leagues. For example, "Xerox is not a dirtball company"....
