15-letter words containing i, n, a, u, d
- graph reduction — A technique invented by Chris Wadsworth where an expression is represented as a directed graph (usually drawn as an inverted tree). Each node represents a function call and its subtrees represent the arguments to that function. Subtrees are replaced by the expansion or value of the expression they represent. This is repeated until the tree has been reduced to a value with no more function calls (a normal form). In contrast to string reduction, graph reduction has the advantage that common subexpressions are represented as pointers to a single instance of the expression which is only reduced once. It is the most commonly used technique for implementing lazy evaluation.

- guru meditation — (operating system) The Amiga equivalent of Unix's panic (sometimes just called a "guru" or "guru event"). When the system crashes, a cryptic message of the form "GURU MEDITATION #XXXXXXXX.YYYYYYYY" may appear, indicating what the problem was. An Amiga guru can figure things out from the numbers. In the earliest days of the Amiga, there was a device called a "Joyboard" which was basically a plastic board built onto a joystick-like device; it was sold with a skiing game cartridge for the Atari game machine. It is said that whenever the prototype OS crashed, the system programmer responsible would concentrate on a solution while sitting cross-legged, balanced on a Joyboard, resembling a meditating guru. Sadly, the joke was removed in AmigaOS 2.04. The Jargon File claimed that a guru event had to be followed by a Vulcan nerve pinch but, according to a correspondent, a mouse click was enough to start a reboot.
