  • electronic banking — the transfer of money between financial institutions through an exchange of electronic signals over a network
  • electronic tagging — Electronic tagging is a system in which a criminal or suspected criminal has an electronic device attached to them which enables the police to know if they leave a particular area.
  • electroretinograms — Plural form of electroretinogram.
  • endangered species — animal, plant becoming extinct
  • environment agency — an official agency providing information on environmental issues, esp rivers, flooding and pollution
  • equinoctial spring — either of the two highest spring tides that occur at the equinoxes
  • euclid's algorithm — (algorithm)   (Or "Euclidean Algorithm") An algorithm for finding the greatest common divisor (GCD) of two numbers. It relies on the identity gcd(a, b) = gcd(a-b, b) To find the GCD of two numbers by this algorithm, repeatedly replace the larger by subtracting the smaller from it until the two numbers are equal. E.g. 132, 168 -> 132, 36 -> 96, 36 -> 60, 36 -> 24, 36 -> 24, 12 -> 12, 12 so the GCD of 132 and 168 is 12. This algorithm requires only subtraction and comparison operations but can take a number of steps proportional to the difference between the initial numbers (e.g. gcd(1, 1001) will take 1000 steps).
  • exercise programme — a programme detailing a range of physical exercises and the amount of time each exercise should be performed, used especially in gymnasiums, where they are typically tailored to individuals' needs
  • feeping creaturism — /fee'ping kree"ch*r-izm/ A deliberate spoonerism for creeping featurism, meant to imply that the system or program in question has become a misshapen creature of hacks. This term isn"t really well defined, but it sounds so neat that most hackers have said or heard it. It is probably reinforced by an image of terminals prowling about in the dark making their customary noises.
  • frederick douglass — Frederick, 1817–95, U.S. ex-slave, abolitionist, and orator.
  • free-range chicken — a chicken kept in natural nonintensive conditions
  • 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.
