  • considered harmful — (programming, humour)   A type of phrase based on the title of Edsger W. Dijkstra's famous note in the March 1968 Communications of the ACM, "Goto Statement Considered Harmful", which fired the first salvo in the structured programming wars. Amusingly, the ACM considered the resulting acrimony sufficiently harmful that it will (by policy) no longer print articles taking so assertive a position against a coding practice. In the ensuing decades, a large number of both serious papers and parodies bore titles of the form "X considered Y". The structured-programming wars eventually blew over with the realisation that both sides were wrong, but use of such titles has remained as a persistent minor in-joke.

  • crookes radiometer — a type of radiometer consisting of an evacuated glass bulb containing a set of lightweight vanes, each blackened on one side. The vanes are mounted on a vertical axis and revolve when light, or other radiant energy, falls on them

  • cultural diffusion — act of diffusing; state of being diffused.
  • cultural diversity — the cultural variety and cultural differences that exist in the world, a society, or an institution: Dying languages and urbanization are threats to cultural diversity.
  • daisywheel printer — (printer)   A kind of impact printer where the characters are arranged on the ends of the spokes of a wheel (resembling the petals on a daisy). The wheel (usually made of plastic) is rotated to select the character to print and then an electrically operated hammer mechanism bends the selected spoke forward slightly, sandwiching an ink ribbon between the character and the paper, as in a typewriter. One advantage of this arrangement over that of a typewriter is that different wheels may be inserted to produce different typefaces.
  • dangerous offender — an offender who is deemed by a court of law to be likely to engage in further violent conduct, and who thus becomes eligible for an indefinite prison sentence
  • data transfer rate — (communications)   (Or "throughput, data rate", "transmission rate") The amount of data transferred in one direction over a link divided by the time taken to transfer it, usually expressed in bits per second (bps), bytes per second (Bps) or baud. The link may be anything from an interface to a hard disk to a radio transmission from a satellite. Where data transfer is not continuous throughout the given time interval, the data transfer rate is thus an average rate that will be lower than the peak rate. The peak or maximum possible rate may itself be lower than the capacity of the communication channel if the channel is shared, or part of the signal is not considered as data, e.g. checksum or routing information. When applied to data rate, the multiplier prefixes "kilo-", "mega-", "giga-", etc. (and their abbreviations, "k", "M", "G", etc.) always denote powers of 1000. For example, 64 kbps is 64,000 bits per second. This contrasts with units of storage where they stand for powers of 1024, e.g. 1 KB = 1024 bytes. The other important characteristic of a channel is its latency. The bandwidth of a channel determines the data transfer rate but is a different characteristic, measured in Hertz. [Relationship?]
  • dead as a doornail — completely dead
  • dead man's fingers — a soft coral, Alcyonium digitatum, with long finger-like polyps
  • dead-man's fingers — any of various fungi, sponges, plant roots, animal parts, etc., having fingerlike projections and a pale or dull color, as the gray-black woodland fungus Xylaria polymorpha or the whitish spongy gills of a food crab.
  • deanthropomorphism — the ridding of philosophy or religion of anthropomorphic beliefs and doctrines.
  • dechristianization — The act of dechristianizing; the systematic removal of Christianity or Christian elements.
  • deep-sea fisherman — a person who takes part in deep-sea fishing
  • defense calculator — IBM 701
  • delmarva peninsula — a peninsula of the northeast US, between Chesapeake Bay and the Atlantic
  • demorgan's theorem — (logic)   A logical theorem which states that the complement of a conjunction is the disjunction of the complements or vice versa. In symbols: not (x and y) = (not x) or (not y) not (x or y) = (not x) and (not y) E.g. if it is not the case that I am tall and thin then I am either short or fat (or both). The theorem can be extended to combinations of more than two terms in the obvious way. The same laws also apply to sets, replacing logical complement with set complement, conjunction ("and") with set intersection, and disjunction ("or") with set union. A (C) programmer might use this to re-write if (!foo && !bar) ... as if (!(foo || bar)) ... thus saving one operator application (though an optimising compiler should do the same, leaving the programmer free to use whichever form seemed clearest).
  • departmental store — a department store.
  • depository library — a library designated by law to receive without charge all or a selection of the official publications of a government.
  • depth-first search — (algorithm)   A graph search algorithm which extends the current path as far as possible before backtracking to the last choice point and trying the next alternative path. Depth-first search may fail to find a solution if it enters a cycle in the graph. This can be avoided if we never extend a path to a node which it already contains. Opposite of breadth first search. See also iterative deepening.
  • descriptive clause — a relative clause that describes or supplements but is not essential in establishing the identity of the antecedent and is usually set off by commas in English. In This year, which has been dry, is bad for crops the clause which has been dry is a nonrestrictive clause.
  • desiderius erasmus — Desiderius [des-i-deer-ee-uh s] /ˌdɛs ɪˈdɪər i əs/ (Show IPA), 1466?–1536, Dutch humanist, scholar, theologian, and writer.
