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.

cursor dipped in x — (jargon) The metaphorical source of the electronic equivalent of a poisoned-pen letter. Derived from English metaphors of the form "pen dipped in X" (where X = e.g. "acid", "bile", "vitriol"). These map over neatly to this hackish usage (the cursor being what moves, leaving letters behind, when one is composing on-line). "Talk about a nastygram! He must've had his cursor dipped in acid when he wrote that one!"
cushing's syndrome — a medical condition characterized by obesity, hypertension, excessive hair growth, etc., caused by an overactive adrenal gland or large doses of corticosteroids
cyrano de bergerac — Savinien (savinjɛ̃). 1619–55, French writer and soldier, famous as a duellist and for his large nose. He became widely known through the verse drama Cyrano de Bergerac (1897) by Edmond Rostand
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?]
datacenter manager — (job) A person who plans and directs all computer and peripheral operations, data entry, data control scheduling and quality control.
de bruijn notation — (language) A variation of lambda notation for specifying functions using numbers instead of names to refer to formal parameters. A reference to a formal parameter is a number which gives the number of lambdas (written as \ here) between the reference and the lambda which binds the parameter. E.g. the function \ f . \ x . f x would be written \ . \ . 1 0. The 0 refers to the innermost lambda, the 1 to the next etc. The chief advantage of this notation is that it avoids the possibility of name capture and removes the need for alpha conversion.
de-differentiation — a process by which structures or behaviors that were specialized for a specific function lose their specialization and become simplified or generalized.
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.
dear john (letter) — a letter from one's fiancée or girlfriend breaking off an engagement or love affair, or from one's wife asking for a divorce
debt restructuring — Debt restructuring is a method of organizing a company's debts in a different way in order to make the company more likely to be able to pay them.
decachlorobiphenyl — (organic compound) The fully chlorinated polychlorinated biphenyl containing ten chlorine atoms.
