- 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.

- diethylstilboestrol — Diethylstilbestrol.
- 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

- extensible database — (database) A DBMS that allows access to data from remote sources as if the remote data were part of the database.
- fall by the wayside — to cease or fail to continue doing something
- 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.
- few and far between — not many but more than one: Few artists live luxuriously.
- first world problem — a fairly minor problem, frustrating situation, or complaint associated with a relatively high standard of living, as opposed to the more serious problems associated with poverty: I’m bored with all my electronic gadgets—such a first world problem!

- foundation subjects — the subjects studied as part of the National Curriculum, including the compulsory core subjects
- 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].
