  • distributed memory — (architecture)   The kind of memory in a parallel processor where each processor has fast access to its own local memory and where to access another processor's memory it must send a message via the inter-processor network. Opposite: shared memory.
  • distribution class — form class

  • energy consumption — amount of energy used
  • engelbart, douglas — Douglas Engelbart
  • 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).
  • evolution strategy — (ES) A kind of evolutionary algorithm where individuals (potential solutions) are encoded by a set of real-valued "object variables" (the individual's "genome"). For each object variable an individual also has a "strategy variable" which determines the degree of mutation to be applied to the corresponding object variable. The strategy variables also mutate, allowing the rate of mutation of the object variables to vary. An ES is characterised by the population size, the number of offspring produced in each generation and whether the new population is selected from parents and offspring or only from the offspring. ES were invented in 1963 by Ingo Rechenberg, Hans-Paul Schwefel at the Technical University of Berlin (TUB) while searching for the optimal shapes of bodies in a flow.
  • extemporaneousness — The degree or property of being extemporaneous.
  • fast-food industry — the industry surrounding fast-food restaurants
  • fibrocartilaginous — a type of cartilage having a large number of fibers.
  • 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.
  • first duke of york — a member of the royal house of England that ruled from 1461 to 1485.
  • first-in first-out — (algorithm)   (FIFO, or "queue") A data structure or hardware buffer from which items are taken out in the same order they were put in. Also known as a "shelf" from the analogy with pushing items onto one end of a shelf so that they fall off the other. A FIFO is useful for buffering a stream of data between a sender and receiver which are not synchronised - i.e. not sending and receiving at exactly the same rate. Obviously if the rates differ by too much in one direction for too long then the FIFO will become either full (blocking the sender) or empty (blocking the receiver). A Unix pipe is a common example of a FIFO. A FIFO might be (but isn't ever?) called a LILO - last-in last-out. The opposite of a FIFO is a LIFO (last-in first-out) or "stack".
  • fitness instructor — physical trainer, exercise teacher
  • fluorescent screen — a transparent screen coated on one side with a phosphor that fluoresces when exposed to X-rays or cathode rays
  • football supporter — a person who supports a particular football team
  • for the rest of us — (abuse)   (From the Macintosh slogan "The computer for the rest of us") 1. Used to describe a spiffy product whose affordability shames other comparable products, or (more often) used sarcastically to describe spiffy but very overpriced products. 2. Describes a program with a limited interface, deliberately limited capabilities, non-orthogonality, inability to compose primitives, or any other limitation designed to not "confuse" a naïve user. This places an upper bound on how far that user can go before the program begins to get in the way of the task instead of helping accomplish it. Used in reference to Macintosh software which doesn't provide obvious capabilities because it is thought that the poor luser might not be able to handle them. Becomes "the rest of *them*" when used in third-party reference; thus, "Yes, it is an attractive program, but it's designed for The Rest Of Them" means a program that superficially looks neat but has no depth beyond the surface flash. See also point-and-drool interface, user-friendly.
