  2. Substitution failure is not an error - Wikipedia

    en.wikipedia.org/wiki/Substitution_failure_is...

    When T has the nested type foobar defined, the instantiation of the first test works and the null pointer constant is successfully passed. (And the resulting type of the expression is yes.) If it does not work, the only available function is the second test, and the resulting type of the expression is no. An ellipsis is used not only because it ...

  3. Lazy evaluation - Wikipedia

    en.wikipedia.org/wiki/Lazy_evaluation

    In programming language theory, lazy evaluation, or call-by-need, [1] is an evaluation strategy which delays the evaluation of an expression until its value is needed (non-strict evaluation) and which also avoids repeated evaluations (by the use of sharing).

  4. Race condition - Wikipedia

    en.wikipedia.org/wiki/Race_condition

    When the input value A changes from low to high, the circuit outputs a short spike of duration (∆t 1 + ∆t 2) − ∆t 2 = ∆t 1. A race condition or race hazard is the condition of an electronics , software , or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events ...

  5. Delay slot - Wikipedia

    en.wikipedia.org/wiki/Delay_slot

    In computer architecture, a delay slot is an instruction slot being executed without the effects of a preceding instruction. [1] The most common form is a single arbitrary instruction located immediately after a branch instruction on a RISC or DSP architecture; this instruction will execute even if the preceding branch is taken.
