- 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.

- hacking x for y — [ITS] Ritual phrasing of part of the information which ITS made publicly available about each user. This information (the INQUIR record) was a sort of form in which the user could fill out various fields. On display, two of these fields were always combined into a project description of the form "Hacking X for Y" (e.g. ""Hacking perceptrons for Minsky""). This form of description became traditional and has since been carried over to other systems with more general facilities for self-advertisement (such as Unix plan files).

- 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.
