  • grain itch mite — a mite, Pyemotes ventricosus, that often occurs in straw and normally feeds on the larvae of insects but opportunistically bites humans, causing an itching dermatitis.
  • 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.
  • graphic granite — a pegmatite that has crystals of gray quartz imbedded in white or pink microcline in such a manner that they resemble cuneiform writing.
  • great sanhedrin — Sanhedrin (def 1).
  • great-sanhedrin — Also called Great Sanhedrin. the highest council of the ancient Jews, consisting of 71 members, and exercising authority from about the 2nd century b.c.
  • green lightning — [IBM] 1. Apparently random flashing streaks on the face of 3278-9 terminals while a new symbol set is being downloaded. This hardware bug was left deliberately unfixed, as some genius within IBM suggested it would let the user know that "something is happening". That, it certainly does. Later microprocessor-driven IBM colour graphics displays were actually *programmed* to produce green lightning! 2. [proposed] Any bug perverted into an alleged feature by adroit rationalisation or marketing. "Motorola calls the CISC cruft in the 88000 architecture "compatibility logic", but I call it green lightning". See also feature.

  • halting problem — The problem of determining in advance whether a particular program or algorithm will terminate or run forever. The halting problem is the canonical example of a provably unsolvable problem. Obviously any attempt to answer the question by actually executing the algorithm or simulating each step of its execution will only give an answer if the algorithm under consideration does terminate, otherwise the algorithm attempting to answer the question will itself run forever. Some special cases of the halting problem are partially solvable given sufficient resources. For example, if it is possible to record the complete state of the execution of the algorithm at each step and the current state is ever identical to some previous state then the algorithm is in a loop. This might require an arbitrary amount of storage however. Alternatively, if there are at most N possible different states then the algorithm can run for at most N steps without looping. A program analysis called termination analysis attempts to answer this question for limited kinds of input algorithm.
