  • exposure compensation — the act of overriding a camera's automatic exposure in order to achieve a particular effect or due to difficult lighting conditions
  • file service protocol — (protocol)   (FSP) A protocol, similar to FTP, for copying files between computers. It's designed for anonymous archives, and has protection against server and network overloading. It doesn't use connections so it can survive interruptions in service. Until 1993-08-12, FSP didn't stand for anything. Wen-King was responsible for the initials and Michael Grubb <[email protected]> for their eventual expansion. Other suggestions were "File Slurping Protocol", "Flaky Stream Protocol" and "FTP's Sexier Partner".

  • foreground processing — a type of processing that supports interaction between interactive and batch operations
  • foreign correspondent — a correspondent, as for a periodical, assigned to send back articles and news dispatches from a foreign country for publication.
  • forensic anthropology — the branch of physical anthropology in which anthropological data, criteria, and techniques are used to determine the sex, age, genetic population, or parentage of skeletal or biological materials in questions of civil or criminal law.
  • framing specification — A specification of the "protocol bits" that surround the "data bits" on a communications channel to allow the data to be "framed" into chunks, like start and stop bits in EIA-232. It allows a receiver to synchronize at points along the data stream.
  • french fried potatoes — a more formal name for chips
  • functional imperative — a requirement for the survival of any social system, as communication, control of conflict, or socialization.
  • gastrohepatic omentum — lesser omentum.
  • 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.
