  • director of music — a person in charge of musical training and performance at an institution such as a college, especially the head bandmaster of a military band
  • directory service — (database, networking)   A structured repository of information on people and resources within an organisation, facilitating management and communication. On a LAN or WAN the directory service identifies all aspects of the network including users, software, hardware, and the various rights and policies assigned to each. As a result applications can access information without knowing where a particular resource is physically located, and users interact oblivious to the network topology and protocols. To allow heterogeneous networks to share directory information the ITU proposed a common structure called X.500. However, its complexity and lack of seamless Internet support led to the development of Lightweight Directory Access Protocol (LDAP) which has continued to evolve under the aegis of the IETF. Despite its name LDAP is too closely linked to X.500 to be "lightweight".
  • disaster recovery — (business)   (DR) Planning and implementation of procedures and facilities for use when essential systems are not available for a period long enough to have a significant impact on the business, e.g. when the head office is blown up. Disasters include natural: fire, flood, lightning, hurricane; hardware: power failure, component failure, head crash; software failure: bugs, resources; vandalism: arson, bombing, cracking, theft; data corruption or loss: human error, media failure; communications: computer network equipment, network storm, telephones; security: passwords compromised, computer virus; legal: change in legislation; personnel: unavailability of essential staff, industrial action. Companies need to plan for disaster: before: risk analysis, preventive measures, training; during: how should staff and systems respond; after: recovery measures, post mortem analysis. Hardware can usually be replaced and is usually insured. Software and data needs to be backed up off site. Alternative communication systems should be arranged in case of network failure or inaccessible premises, e.g. emergency telephone number, home working, alternative data center.

  • dissociated press — [Play on "Associated Press"; perhaps inspired by a reference in the 1949 Bugs Bunny cartoon "What's Up, Doc?"] An algorithm for transforming any text into potentially humorous garbage even more efficiently than by passing it through a marketroid. The algorithm starts by printing any N consecutive words (or letters) in the text. Then at every step it searches for any random occurrence in the original text of the last N words (or letters) already printed and then prints the next word or letter. Emacs has a handy command for this. Here is a short example of word-based Dissociated Press applied to an earlier version of the Jargon File: wart: A small, crocky feature that sticks out of an array (C has no checks for this). This is relatively benign and easy to spot if the phrase is bent so as to be not worth paying attention to the medium in question. Here is a short example of letter-based Dissociated Press applied to the same source: window sysIWYG: A bit was named aften /bee't*/ prefer to use the other guy's re, especially in every cast a chuckle on neithout getting into useful informash speech makes removing a featuring a move or usage actual abstractionsidered interj. Indeed spectace logic or problem! A hackish idle pastime is to apply letter-based Dissociated Press to a random body of text and vgrep the output in hopes of finding an interesting new word. (In the preceding example, "window sysIWYG" and "informash" show some promise.) Iterated applications of Dissociated Press usually yield better results. Similar techniques called "travesty generators" have been employed with considerable satirical effect to the utterances of Usenet flamers; see pseudo.
