  • 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.
  • constructive proof — (mathematics)   A proof that something exists that provides an example or a method for actually constructing it. For example, for any pair of finite real numbers n < 0 and p > 0, there exists a real number 0 < k < 1 such that f(k) = (1-k)*n + k*p = 0. A constructive proof would proceed by rearranging the above to derive an equation for k: k = 1/(1-n/p) From this and the constraints on n and p, we can show that 0 < k < 1. A few mathematicians actually reject *all* non-constructive arguments as invalid; this means, for instance, that the law of the excluded middle (either P or not-P must hold, whatever P is) has to go; this makes proof by contradiction invalid. See intuitionistic logic. Constructive proofs are popular in theoretical computer science, both because computer scientists are less given to abstraction than mathematicians and because intuitionistic logic turns out to be an appropriate theoretical treatment of the foundations of computer science.
  • corps of engineers — a branch of the U.S. Army responsible for military and many civil engineering projects.
  • corridors of power — the higher echelons of government, the Civil Service, etc, considered as the location of power and influence
  • court of st. james — the British royal court
  • creeping featurism — (jargon)   /kree'ping fee'chr-izm/ (Or "feature creep") A systematic tendency to load more chrome and features onto systems at the expense of whatever elegance they may have possessed when originally designed. "The main problem with BSD Unix has always been creeping featurism." More generally, creeping featurism is the tendency for anything to become more complicated because people keep saying "Gee, it would be even better if it had this feature too". The result is usually a patchwork because it grew one ad-hoc step at a time, rather than being planned. Planning is a lot of work, but it's easy to add just one extra little feature to help someone, and then another, and another, .... When creeping featurism gets out of hand, it's like a cancer. Usually this term is used to describe computer programs, but it could also be said of the federal government, the IRS 1040 form, and new cars. A similar phenomenon sometimes afflicts conscious redesigns; see second-system effect. See also creeping elegance.
  • creme de framboise — a liqueur flavored with raspberries.
  • crested flycatcher — any of various tyrant flycatchers (esp. genus Myiarchus) with a prominent crest
  • crocodile-infested — full of crocodiles
  • cultural diffusion — act of diffusing; state of being diffused.
  • curvature of space — (in relativity) a property of space near massive bodies in which their gravitational field causes light to travel along curved paths.
  • 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 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.

  • defense calculator — IBM 701
  • degrees of freedom — the number of independent variables entering into a statistical measure or frequency distribution
  • deliver oneself of — to speak with deliberation or at length
  • 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.
  • diaminofluorescein — (organic compound) A fluorescein into which two amino groups have been substituted.
  • disenfranchisement — to disfranchise.
  • distress frequency — a radio frequency band reserved for emergency signals from aircraft or ships in distress.

  • due process of law — the administration of justice in accordance with established rules and principles
  • duty-free shopping — the making of duty-free purchases
  • dwarf storage unit — (humour)   (DSU) An IBM term for a cupboard.
  • eleanor of castile — 1246–90, Spanish wife of Edward I of England. Eleanor Crosses were erected at each place at which her body rested between Nottingham, where she died, and London, where she is buried
  • excess profits tax — a tax on profits exceeding a certain amount
  • fallot's tetralogy — a congenital heart disease in which there are four defects: pulmonary stenosis, enlarged right ventricle, a ventricular septal defect, and an aorta whose origin lies over the septal defect. In babies suffering this disease the defects can be corrected by surgery
