  • feldenkrais method — a system of gentle movements that promote flexibility, coordination, and self-awareness
  • fermat's last post — (humour)   A post to a bug tracker, mailing list or forum in which the author claims to have found a simple fix or workaround for a bug, but never says what it is and never shows up again to explain it (even after others have been puzzling over the bug for years).
  • fermat's principle — Optics. the law that the path taken by a ray of light in going from one point to another point will be the path that requires the least time.
  • ferrite-rod aerial — a type of aerial, normally used in radio reception, consisting of a small coil of wire mounted on a ferrite core, the coil serving as a tuning inductance
  • fettuccine alfredo — fettuccine in cream sauce with grated Parmesan cheese.
  • filename extension — (filename extension)   The portion of a filename, following the final point, which indicates the kind of data stored in the file - the file type. Many operating systems use filename extensions, e.g. Unix, VMS, MS-DOS, Microsoft Windows. They are usually from one to three letters (some sad old OSes support no more than three). Examples include "c" for C source code, "ps" for PostScript, "txt" for arbitrary text. Apart from informing the user what type of content the file holds, filename extensions are typically used to decide which program to launch when a file is "run", e.g. by double-clicking it in a GUI file browser. They are also used by Unix's make to determine how to build one kind of file from another. Compare: MIME type.
  • finite-dimensional — (of a vector space) having a basis consisting of a finite number of elements.
  • first class module — (programming)   A module that is a first class data object of the programming language, e.g. a record containing functions. In a functional language, it is standard to have first class programs, so program building blocks can have the same status.
  • fitzwilliam museum — a museum, attached to Cambridge University and founded in 1816, noted esp for its paintings and collections devoted to the applied arts
  • flame-of-the-woods — an Indian evergreen shrub, Ixora coccinea, of the madder family, having red, tubular flowers in dense clusters.
  • flash butt welding — a method of welding metal edge-to-edge with a powerful electric flash followed by the application of pressure.
  • flat address space — (architecture)   The memory architecture in which any memory location can be selected from a single contiguous block by a single integer offset. Almost all popular processors have a flat address space, but the Intel x86 family has a segmented address space. A flat address space greatly simplifies programming because of the simple correspondence between addresses (pointers) and integers.
  • flat file database — (database)   A database containing a single table, stored in a single flat file, often in a human-readable format such as comma-separated values or fixed-width columns.
  • flat on one's back — lying supine
  • flat-bottomed rail — a rail having a cross section like an inverted T, with the top extremity enlarged slightly to form the head
  • flat-panel display — a type of thin, lightweight video display that uses liquid crystals or electroluminescence to reflect images.
  • floating underflow — underflow
  • floating-rate note — a eurobond, often issued as a negotiable bearer bond, that has a floating rate of interest
  • flotsam and jetsam — the part of the wreckage of a ship and its cargo found floating on the water. Compare jetsam, lagan.
  • flower arrangement — floral display
  • fly in the face of — to move through the air using wings.
  • fly off the handle — a part of a thing made specifically to be grasped or held by the hand.
  • football supporter — a person who supports a particular football team
  • forward compatible — forward compatibility
  • free-range poultry — poultry kept in natural nonintensive conditions
  • fringe-toed lizard — an iguanid lizard, Uma notata, of sandy deserts of the western U.S. and Mexico, having a wedge-shaped snout and toes fringed with long, pointed scales.
  • fulminating powder — powder that explodes by percussion.
  • functional disease — a disease in which there is an abnormal change in the function of an organ, but no structural alteration in the tissues involved (opposed to organic disease).
  • functional testing — (testing)   (Or "black-box testing", "closed-box testing") The application of test data derived from functional requirements without regard to how the system is implemented.
  • gainful employment — an occupation that pays an income
  • galactic longitude — the angular distance in degrees measured eastward in the galactic plane from a radius drawn from the earth as center to the constellation Sagittarius.
  • galilean satellite — any of the four large satellites of the planet Jupiter – Io, Europa, Ganymede, or Callisto – discovered in 1610 by Galileo
  • galilean telescope — a refracting telescope that forms an erect image, consisting of an objective of relatively long focal length that causes light rays to converge and an eyepiece of short focal length that causes them to diverge.
  • garbage collection — (programming)   (GC) The process by which dynamically allocated storage is reclaimed during the execution of a program. The term usually refers to automatic periodic storage reclamation by the garbage collector (part of the run-time system), as opposed to explicit code to free specific blocks of memory. Automatic garbage collection is usually triggered during memory allocation when the amount free memory falls below some threshold or after a certain number of allocations. Normal execution is suspended and the garbage collector is run. There are many variations on this basic scheme. Languages like Lisp represent expressions as graphs built from cells which contain pointers and data. These languages use automatic dynamic storage allocation to build expressions. During the evaluation of an expression it is necessary to reclaim space which is used by subexpressions but which is no longer pointed to by anything. This reclaimed memory is returned to the free memory pool for subsequent reallocation. Without garbage collection the program's memory requirements would increase monotonically throughout execution, possibly exceeding system limits on virtual memory size. The three main methods are mark-sweep garbage collection, reference counting and copying garbage collection. See also the AI koan about garbage collection.
  • garden loosestrife — any of various plants belonging to the genus Lysimachia, of the primrose family, having clusters of usually yellow flowers, as L. vulgaris (garden loosestrife) or L. quadrifolia (whorled loosestrife)

  • geometrical optics — the branch of optics dealing with light as rays, especially in the study of the effects of lenses and mirrors on light beams and of their combination in optical instruments.
  • gestalt psychology — (sometimes lowercase) the theory or doctrine that physiological or psychological phenomena do not occur through the summation of individual elements, as reflexes or sensations, but through gestalts functioning separately or interrelatedly.
  • gilbert and george — a team of artists, Gilbert Proesch, Italian, born 1942, and George Passmore, British, born 1943: noted esp for their photomontages and performance works
