- instruction scheduling — The compiler phase that orders instructions on a pipelined, superscalar, or VLIW architecture so as to maximise the number of function units operating in parallel and to minimise the time they spend waiting for each other. Examples are filling a delay slot; interspersing floating-point instructions with integer instructions to keep both units operating; making adjacent instructions independent, e.g. one which writes a register and another which reads from it; separating memory writes to avoid filling the write buffer.

Wall, "Available Instruction-Level Parallelism for Superscalar and Superpipelined Processors", Proceedings of the Third International Conference on Architectural Support for Programming Languages and Operating Systems, pp. 272--282, 1989.

- national semiconductor — (company) A semiconductor manufacturer, responsible for the SC/MP, National Semiconductor 16000 and National Semiconductor 32000 series of microprocessors.
- nominal semidestructor — (abuse) Slang for "National Semiconductor", found among other places in the 4.3BSD networking sources. During the late 1970s to mid-1980s this company marketed a series of microprocessors including the National Semiconductor 16000 and National Semiconductor 32000. At one point early in the great microprocessor race, the specs on these chips made them look like serious competition for the rising Intel 80x86 and Motorola 680x0 series. Unfortunately, the actual parts were notoriously flaky and never implemented the full instruction set promised in their literature, apparently because the company couldn't get any of the mask steppings to work as designed. They eventually sank without trace, joining the Zilog Z8000 and a few even more obscure also-rans in the graveyard of forgotten microprocessors.
- non-euclidean geometry — geometry based upon one or more postulates that differ from those of Euclid, especially from the postulate that only one line may be drawn through a given point parallel to a given line.
- nondestructive testing — any of several methods of detecting flaws in metals without causing damage. The most common techniques involve the use of X-rays, gamma rays, and ultrasonic vibrations
- normal order reduction — Under this evaluation strategy an expression is evaluated by reducing the leftmost outermost redex first. This method will terminate for any expression for which termination is possible, whereas applicative order reduction may not. This method is equivalent to passing arguments unevaluated because arguments are initially to the right of functions applied to them. See also computational adequacy theorem.
- object-oriented turing — (language) An extension of Turing and a replacement for Turing Plus by R.C. Holt <[email protected]>, U Toronto, 1991. Object-Oriented Turing supports imperative programming, object-oriented programming and concurrent programming. It has modules, classes, single inheritance, processes, exception handling and optional machine-dependent programming. There is an integrated environment under the X Window System and a demo version. Versions exist for Sun-4, MIPS, RS-6000 and others. E-mail: <[email protected]>.

- open source definition — (standard) (OSD) Definition of distribution terms for open source software, promoted by the Open Source Initiative.
- ousterhout's dichotomy — (language) John Ousterhout's division of high-level languages into "system programming languages" and "scripting languages". This distinction underlies the design of his language Tcl. System programming languages (or "applications languages") are strongly typed, allow arbitrarily complex data structures, and programs in them are compiled, and are meant to operate largely independently of other programs. Prototypical system programming languages are C and Modula-2. By contrast, scripting languages (or "glue languages") are weakly typed or untyped, have little or no provision for complex data structures, and programs in them ("scripts") are interpreted. Scripts need to interact either with other programs (often as glue) or with a set of functions provided by the interpreter, as with the file system functions provided in a UNIX shell and with Tcl's GUI functions. Prototypical scripting languages are AppleScript, C Shell, MS-DOS batch files and Tcl. Many believe that this is a highly arbitrary dichotomy, and refer to it as "Ousterhout's fallacy" or "Ousterhout's false dichotomy". While strong-versus-weak typing, data structure complexity, and independent versus stand-alone might be said to be unrelated features, the usual critique of Ousterhout's dichotomy is of its distinction of compilation versus interpretation, since neither semantics nor syntax depend significantly on whether code is compiled into machine-language, interpreted, tokenized, or byte-compiled at the start of each run, or any mixture of these. Many languages fall between being interpreted or compiled (e.g. Lisp, Forth, UCSD Pascal, Perl, and Java). This makes compilation versus interpretation a dubious parameter in a taxonomy of programming languages.
