  • generic type variable — (programming)   (Also known as a "schematic type variable"). Different occurrences of a generic type variable in a type expression may be instantiated to different types. Thus, in the expression let id x = x in (id True, id 1) id's type is (for all a: a -> a). The universal quantifier "for all a:" means that a is a generic type variable. For the two uses of id, a is instantiated to Bool and Int. Compare this with let id x = x in let f g = (g True, g 1) in f id This looks similar but f has no legal Hindley-Milner type. If we say f :: (a -> b) -> (b, b) this would permit g's type to be any instance of (a -> b) rather than requiring it to be at least as general as (a -> b). Furthermore, it constrains both instances of g to have the same result type whereas they do not. The type variables a and b in the above are implicitly quantified at the top level: f :: for all a: for all b: (a -> b) -> (b, b) so instantiating them (removing the quantifiers) can only be done once, at the top level. To correctly describe the type of f requires that they be locally quantified: f :: ((for all a: a) -> (for all b: b)) -> (c, d) which means that each time g is applied, a and b may be instantiated differently. f's actual argument must have a type at least as general as ((for all a: a) -> (for all b: b)), and may not be some less general instance of this type. Type variables c and d are still implicitly quantified at the top level and, now that g's result type is a generic type variable, any types chosen for c and d are guaranteed to be instances of it. This type for f does not express the fact that b only needs to be at least as general as the types c and d. For example, if c and d were both Bool then any function of type (for all a: a -> Bool) would be a suitable argument to f but it would not match the above type for f.

  • mean time to recovery — (specification)   (MTTR) The average time that a device will take to recover from a non-terminal failure. Examples of such devices range from self-resetting fuses (where the MTTR would be very short, probably seconds), up to whole systems which have to be replaced. The MTTR would usually be part of a maintenance contract, where the user would pay more for a system whose MTTR was 24 hours, than for one of, say, 7 days. This means the supplier is guaranteeing to have the system up and running again within 24 hours (or 7 days) of being notified of the failure. Some devices have a MTTR of zero, which means that they have redundant components which can take over the instant the primary one fails, see RAID for example. See also Mean Time Between Failures.

  • overuse strain injury — (medical)   (Or "repetitive strain injury", RSI, "repetitive strain disorder") Any tendon or muscle injury resulting from overuse, usually in the hand, wrist, or arm. Injury may be caused by any combination of repetitive, unacustomed, or prolonged movements, forcefulness, or an awkward position (often due to bad ergonomics). The symptoms are pain, tingling, weakness, numbness, swelling, cracking, stiffness, or reduced coordination. Common conditions are: Carpal tunnel syndrome, where swelling of the membrane linings in your wrist surrounding the tendons that bend your fingers compresses the median nerve. This may result in numbness and pain in the hand, arm, shoulder, and neck. Tennis elbow, where rotating your wrist and using force causes a form of epicondylitis. Tendinitis, where unacustomed exercise or repeated awkward movements inflame wrist, elbow, or shoulder tendons, often leading to severe stiffness. Trigger finger, a popping or catching sensation when you bend your finger, wrist, or shoulder. This form of tenosynovitis is caused by repetitive hand movements. To prevent the condition worsening, treat the pain with heat, cold, or aspirin, ibuprofen, or naproxen sodium; rest; or immobilise the injured area with a splint or bandage. See a doctor.
  • path coverage testing — (testing)   Testing a program by examining which lines of executable code are visited (as in code coverage testing) and also the ways of getting to each line of code and the subsequent sequence of execution. Path coverage testing is the most comprehensive type of testing that a test suite can provide. It can find more bugs, especially those that are caused by data coupling. However, path coverage is hard and usually only used for small and/or critical sections of code.
  • personality inventory — a questionnaire designed to measure personality types or characteristics.
