  • gastrohepatic omentum — lesser omentum.
  • gender disappointment — a feeling of depression or anxiety experienced by an expectant parent when the gender of the baby does not match his or her preference
  • 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.

  • gobject introspection — (programming)   A GNOME project that defines a syntax for introspection annotation pragmas to be used in the GObject library source code. Rather than actual introspection, these are intended to allow automatic generation of bindings (APIs) to expose the library to higher-level languages. The sort of information provided is the type and direction (in, out, inout) of function parameters and the responsibility for freeing memory used by data structures.

  • keep the ball rolling — a spherical or approximately spherical body or shape; sphere: He rolled the piece of paper into a ball.
  • lap and diagonal belt — A lap and diagonal belt is a strap attached to a seat in a vehicle that extends horizontally in front of the hips and diagonally from the outer shoulder across the chest. You fasten it across your body in order to prevent yourself being thrown out of the seat if there is a sudden movement or stop.

  • negative prescription — the barring of adverse claims to property, etc, after a specified period of time has elapsed, allowing the possessor to acquire title
  • non-repeating decimal — a decimal representation of any irrational number, having the property that no sequence of digits is repeated ad infinitum.

  • open graphics library — (graphics, library)   (OpenGL) A multi-platform software interface to graphics hardware, supporting rendering and imaging operations. The OpenGL interface was developed by Silicon Graphics, who license it to other vendors. The OpenGL graphics interface consists of several hundred functions operating on 2D and 3D objects, supporting basic techniques, such as modelling and smooth shading, and advanced techniques, such as texture mapping and motion blur. Many operations require a frame buffer. OpenGL is network-transparent, and a common extension to the X Window System allows an OpenGL client to communicate across a network with a different vendor's OpenGL server. OpenGL is based on Silicon Graphics' proprietary IRIS GL.
  • open trading protocol — Internet Open Trading Protocol
  • opposed-piston engine — a reciprocating engine, as a diesel engine, in which each cylinder has two pistons that move simultaneously away from or toward the center.
  • opposite-sex marriage — (broadly) any of the diverse forms of interpersonal union established in various parts of the world to form a familial bond that is recognized legally, religiously, or socially, granting the participating partners mutual conjugal rights and responsibilities and including, for example, opposite-sex marriage, same-sex marriage, plural marriage, and arranged marriage: Anthropologists say that some type of marriage has been found in every known human society since ancient times. See Word Story at the current entry.
  • orthogonal projection — a two-dimensional graphic representation of an object in which the projecting lines are at right angles to the plane of the projection. Also called orthogonal projection. Compare isometric (def 5).
  • pacific daylight time — the version of Pacific Standard Time that is in use when daylight saving time is being observed
  • packed encoding rules — (protocol, standard)   (PER) ASN.1 encoding rules for producing a compact transfer syntax for data structures described in ASN.1, defined in 1994. PER provides a much more compact encoding then BER. It tries to represents the data units using the minimum number of bits. The compactness requires that the decoder knows the complete abstract syntax of the data structure to be decoded, however. Documents: ITU-T X.691, ISO 8825-2.
  • 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.
  • performance-enhancing — noting or relating to a drug or other substance used to improve one's performance in a sport or other activity requiring strength, stamina, etc.: The use of performance-enhancing steroids by athletes is banned.
  • physically challenged — See example at challenged (def 1).
  • plate glass insurance — Plate glass insurance is insurance coverage against damage to or breakage of large panes of glass such as shop windows.
