19-letter words containing d, i, r, g

  • debugging by printf — (programming)   The debugging technique where the programmer inserts print statements into a program so that when run the program leaves a "trail of breadcrumbs" allowing him to see which parts were executed. The information output may just be a short string to indicate that a particular point in the code has been reached or it might be a complete stack trace. The output typically just goes to the window or terminal in which the program is running or may be written to a log file.
  • dendrochronological — Pertaining to dendrochronology.
  • descriptive grammar — an approach to grammar that is concerned with reporting the usage of native speakers without reference to proposed norms of correctness or advocacy of rules based on such norms.
  • design in real time — (programming)   (Dirt) A user interface builder for the X Window System by R. Hesketh.
  • diamond ring effect — a phenomenon, sometimes observed immediately before and after a total eclipse of the sun, in which one of Baily's beads is much brighter than the others, resembling a diamond ring around the moon.
  • dielectric strength — the maximum voltage that can be applied to a given material without causing it to break down, usually expressed in volts or kilovolts per unit of thickness.
  • diffraction grating — a band of equidistant, parallel lines, usually more than 5000 per inch (2000 per centimeter), ruled on a glass or polished metal surface for diffracting light to produce optical spectra.
  • dig one's own grave — If you say that someone is digging their own grave, you are warning them that they are doing something foolish or dangerous that will cause their own failure.
  • 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.
  • digital electronics — (electronics)   The implementation of two-valued logic using electronic logic gates such as and gates, or gates and flip-flops. In such circuits the logical values true and false are represented by two different voltages, e.g. 0V for false and +5V for true. Similarly, numbers are normally represented in binary using two different voltages to represented zero and one. Digital electronics contrasts with analogue electronics which represents continuously varying quantities like sound pressure using continuously varying voltages. Digital electronics is the foundation of modern computers and digital communications. Massively complex digital logic circuits with millions of gates can now be built onto a single integrated circuit such as a microprocessor and these circuits can perform millions of operations per second.
  • digital linear tape — (storage)   (DLT) A kind of magnetic tape drive originally developed by DEC and now marketed by Quantum. DLT drives implement the Digital Lempel Ziv 1 (DLZ1) compression algorithm in a combination of hardware and firmware. They use a popular chip by Stac (now hi/fn) to do the string searching. Counting, sorting and Huffman coding are done in firmware (with hardware support for the Huffman algorithm?). In April 1997 DLT drives can transfer 5 megabytes per second and can store 35 gigabytes on a single cartridge. Compression might roughly double these figures.
  • digital photography — the taking or manipulation of photographs that are stored as data files on a computer.
  • diminishing returns — any rate of profit, production, benefits, etc., that beyond a certain point fails to increase proportionately with added investment, effort, or skill.
  • direct grant school — (in Britain, formerly) a school financed by endowment, fees, and a state grant conditional upon admittance of a percentage of nonpaying pupils nominated by the local education authority
  • display advertising — display ads taken collectively.
  • ditty bag (or box) — a small bag (or box) used as by sailors for holding sewing equipment, toilet articles, etc.
  • diversified farming — the practice of producing a variety of crops or animals, or both, on one farm, as distinguished from specializing in a single commodity.
  • do not disturb sign — A do not disturb sign is a sign that a guest in a hotel hangs outside their room to tell other people not to knock the door or enter.
  • double-helical gear — herringbone gear.
  • drawing-room comedy — a light, sophisticated comedy typically set in a drawing room with characters drawn from polite society.
  • dry-bulk cargo ship — a ship that carries an unpackaged dry cargo such as coal or grain; bulk carrier
  • dwight d eisenhower — Dwight David ("Ike") 1890–1969, U.S. general and statesman: Chief of Staff 1945–48; 34th president of the U.S. 1953–61.
  • electrocardiographs — Plural form of electrocardiograph.
  • electrocardiography — The measurement of electrical activity in the heart and the recording of such activity as a visual trace (on paper or on an oscilloscope screen), using electrodes placed on the skin of the limbs and chest.
  • error-based testing — (programming)   Testing where information about programming style, error-prone language constructs, and other programming knowledge is applied to select test data capable of detecting faults, either a specified class of faults or all possible faults.
  • euclidean algorithm — Euclid's Algorithm
  • feather-tail glider — pygmy glider.
  • finite differencing — strength reduction
  • first degree murder — the most serious category of murder
  • first-degree murder — Law. the killing of another human being under conditions specifically covered in law. In the U.S., special statutory definitions include murder committed with malice aforethought, characterized by deliberation or premeditation or occurring during the commission of another serious crime, as robbery or arson (first-degree murder) and murder by intent but without deliberation or premeditation (second-degree murder)
  • fixed exchange rate — finance: set rate of exchange
  • fixed-rate mortgage — a home mortgage for which equal monthly payments of interest and principal are paid over the life of the loan, usually for a term of 30 years.
  • fixed-wing aircraft — a heavier-than-air aircraft capable of flight whose lift is generated not by wing motion relative to the aircraft, but by forward motion through the air
  • for crying out loud — exasperation
  • forward engineering — (process)   The traditional process of moving from high-level abstractions and logical, implementation-independent designs to the physical implementation of a system. Contrast reverse engineering.
  • forward integration — the acquisition of all or part of a distribution chain by a firm that sells the goods distributed, so that the firm becomes or become closer to the direct seller of the goods

  • front-end financing — money or costs required or incurred in advance of a project in order to get it under way
  • future date testing — (testing)   The process of setting a computer's date to a future date to test a program's (expected or unexpected) date sensitivity. Future date testing only shows the effects of dates on the computer(s) under scrutiny, it does not take into account knock-on effects of dates on other connected systems.
  • galactic coordinate — Usually, galactic coordinates. a member of a system of coordinates that define the position of a celestial body with reference to the Milky Way.
  • gedanken experiment — thought experiment.
  • gender reassignment — the alteration, by surgery and hormone treatments, of a person's physical sex characteristics to approximate those of the opposite sex: Born male, she now lives as a woman but has no plans for a sex change.

  • geothermal gradient — the increase in temperature with increasing depth within the earth.
  • gigabits per second — (unit)   (Gbps) A unit of information transfer rate equal to one billion bits per second. Note that, while a gigabit is defined as a power of two (2^30 bits), a gigabit per second is defined as a power of ten (10^9 bits per second, which is slightly less) than 2^30).
  • giraldus cambrensis — literary name of Gerald de Barri. ?1146–?1223, Welsh chronicler and churchman, noted for his accounts of his travels in Ireland and Wales
