  • creeping cinquefoil — any of several plants belonging to the genus Potentilla, of the rose family, having yellow, red, or white five-petaled flowers, as P. reptans (creeping cinquefoil) of the Old World, or P. argentea (silvery cinquefoil) of North America.
  • creeping featuritis — (jargon)   /kree'ping fee'-chr-i:`t*s/ A variant of creeping featurism, with its own spoonerism: "feeping creaturitis". Some people like to reserve this form for the disease as it actually manifests in software or hardware, as opposed to the lurking general tendency in designers' minds. -ism means "condition" or "pursuit of", whereas -itis usually means "inflammation of".

  • dictionary of names — a dictionary of given names that indicates whether a name is usually male, female, or unisex and often includes origins as well as meanings; for example, as by indicating that Evangeline, meaning “good news,” comes from Greek. Used primarily as an aid in selecting a name for a baby, dictionaries of names may also include lists of famous people who have shared a name and information about its current popularity ranking.
  • difference equation — (mathematics)   A relation between consecutive elements of a sequence. The first difference is D u(n) = u(n+1) - u(n) where u(n) is the nth element of sequence u. The second difference is u(n+2) + a u(n+1) + b u(n) = 0 can be converted to a difference equation (in this case, a second order linear difference equation): D2 u(n) + p D u(n) + q u(n) = 0 and vice versa. a, b, p, q are constants.
  • differential backup — (operating system)   A kind of backup that copies all files that have changed since the last full backup. Each differential backup will include all files in previous differential backups since the full backup so to restore a version of a file, you only need to search the full backup and the relevant differential backup. Some systems support differential backup by associating an "Archive" flag with each file and setting this flag whenever the file is modified to indicate that it should be included in the next backup. A differential backup does not change this flag, whereas an incremental backup resets it.
  • diffraction pattern — the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern) at the edge of a shadow.
  • digital certificate — (communications, security)   An attachment to an electronic mail message used for security purposes, e.g. to verify that a user sending a message is who he or she claims to be, and to provide the receiver with the means to encode a reply. An individual wishing to send an encrypted message applies for a digital certificate from a certificate authority (CA). The CA issues an encrypted digital certificate containing the applicant's public key and a variety of other identification information. The CA makes its own public key readily available on the Internet. The recipient of an encrypted message uses the CA's public key to decode the digital certificate attached to the message, verifies it as issued by the CA and then obtains the sender's public key and identification information held within the certificate.
  • director of studies — a member of staff at an educational institution who has responsibility for overseeing the curriculum
  • disciples of christ — a Christian denomination, founded in the U.S. by Alexander Campbell in the early part of the 19th century, that rejects all creeds, holds the Bible as a sufficient rule of faith and practice, administers baptism by immersion, celebrates the Lord's Supper every Sunday, and has a congregational polity.
  • disenfranchisements — Plural form of disenfranchisement.
  • distinctive feature — a feature of the sound system of a language that serves as the crucial distinguishing mark between two phonemes, as the distinctive feature of voicing, which distinguishes b from p in English, or nasality, which distinguishes m from b and p.

  • efficiency engineer — a person whose work is to increase the productive efficiency of a business or industry by finding better methods of performing various operations, reducing waste and costs, etc.

  • female circumcision — clitoridectomy.
  • ferrite core memory — (storage)   (Or "core") An early form of non-volatile storage built (by hand) from tiny rings of magnetisable material threaded onto very fine wire to form large (e.g. 13"x13" or more) rectangluar arrays. Each core stored one bit of data. These were sandwiched between printed circuit boards(?). Sets of wires ran horizontally and vertically and where a vertical and horizontal wire crossed, a core had both wires threaded through it. A single core could be selected and magnetised by passing sufficient current through its horizontal and vertical wires. A core would retain its magnetisation until it was re-magnetised. The two possible polarities of magnetisation were used to represent the binary values zero and one. A third "sense" wire, passed through the core and, if the magnetisation of the core was changed, a small pulse would be induced in the sense wire which could be detected and used to deduce the core's original state. Some core memory was immersed in a bath of heated oil to improve its performance. Core memory was rendered obsolete by semiconductor memory. For example, the 1970s-era NCR 499 had two boards, each with 16 kilobytes of core memory.
  • feynman, richard p. — Richard P. Feynman
