  • de broglie equation — the postulate of wave mechanics that a particle of mass m moving at a velocity v will have the properties of a wave of wavelength h / mv (de Broglie wavelength) where h is Planck's constant.
  • deoxyribonucleotide — an ester of a deoxyribonucleoside and phosphoric acid; a constituent of DNA.
  • department of labor — the department of the U.S. federal government that promotes and improves the welfare, opportunities, and working conditions of wage earners. Abbreviation: DOL.
  • dependable software — software reliability
  • detective constable — a police officer who investigates crime and who is of the lowest rank
  • 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.
  • disablement benefit — (in Britain) a noncontributory benefit payable to a person disabled through injury or disease caused by their work
  • distinguishableness — The state or quality of being distinguishable.
  • do one's level best — If you say that you will do your level best to do something, you are emphasizing that you will try as hard as you can to do it, even if the situation makes it very difficult.

  • extendible compiler — (language)   (ETC) A Fortran-like compiler that can be extended with macros.
  • extensible database — (database)   A DBMS that allows access to data from remote sources as if the remote data were part of the database.
  • fault-based testing — (testing)   Software testing using test data designed to demonstrate the absence of a set of pre-specified faults; typically, frequently occurring faults. For example, to demonstrate that the software handles or avoids divide by zero correctly, the test data would include zero.

  • florida velvet bean — a tropical vine, Mucuna deeringiana, of the legume family, having showy, purple flowers in drooping clusters and black, hairy pods: grown as an ornamental.
  • functional database — (database, language)   A database which uses a functional language as its query language. Databases would seem to be an inappropriate application for functional languages since, a purely functional language would have to return a new copy of the entire database every time (part of) it was updated. To be practically scalable, the update mechanism must clearly be destructive rather than functional; however it is quite feasible for the query language to be purely functional so long as the database is considered as an argument. One approach to the update problem would use a monad to encapsulate database access and ensure it was single threaded. Alternative approaches have been suggested by Trinder, who suggests non-destructive updating with shared data structures, and Sutton who uses a variant of a Phil Wadler's linear type system. There are two main classes of functional database languages. The first is based upon Backus' FP language, of which FQL is probably the best known example. Adaplan is a more recent language which falls into this category. More recently, people have been working on languages which are syntactically very similar to modern functional programming languages, but which also provide all of the features of a database language, e.g. bulk data structures which can be incrementally updated, type systems which can be incrementally updated, and all data persisting in a database. Examples are PFL [Poulovassilis&Small, VLDB-91], and Machiavelli [Ohori et al, ACM SIGMOD Conference, 1998].
  • gentile da fabriano — 1370?–1427, Italian painter.
  • goldbach conjecture — an unproved theorem that every even integer greater than 2 can be written as the sum of two prime numbers.
  • hamiltonian problem — (computability)   (Or "Hamilton's problem") A problem in graph theory posed by William Hamilton: given a graph, is there a path through the graph which visits each vertex precisely once (a "Hamiltonian path")? Is there a Hamiltonian path which ends up where it started (a "Hamiltonian cycle" or "Hamiltonian tour")? Hamilton's problem is NP-complete. It has numerous applications, sometimes completely unexpected, in computing.
