- digital equipment corporation — (company, hardware) (DEC) A computer manufacturer and software vendor. Before the killer micro revolution of the late 1980s, hackerdom was closely symbiotic with DEC's pioneering time-sharing machines. The first of the group of hacker cultures nucleated around the PDP-1 (see TMRC). Subsequently, the PDP-6, PDP-10, PDP-20, PDP-11 and VAX were all foci of large and important hackerdoms and DEC machines long dominated the ARPANET and Internet machine population. The first PC from DEC was a CP/M computer called Rainbow, announced in 1981-82. DEC was the technological leader of the minicomputer era (roughly 1967 to 1987), but its failure to embrace microcomputers and Unix early cost it heavily in profits and prestige after silicon got cheap. However, the microprocessor design tradition owes a heavy debt to the PDP-11 instruction set, and every one of the major general-purpose microcomputer operating systems so far (CP/M, MS-DOS, Unix, OS/2) were either genetically descended from a DEC OS, or incubated on DEC hardware or both. Accordingly, DEC is still regarded with a certain wry affection even among many hackers too young to have grown up on DEC machines. The contrast with IBM is instructive. Quarterly sales $3923M, profits -$1746M (Aug 1994). DEC was taken over by Compaq Computer Corporation in 1998. In 2002 Compaq was in turn acquired by Hewlett-Packard who sold off parts of Digital Equipment Corporation to Intel and absorbed the rest. The Digital logo is no longer used.

- interface definition language — (IDL) 1. An OSF standard for defining RPC stubs. 2. Part of an effort by Project DOE at SunSoft, Inc. to integrate distributed object technology into the Solaris operating system. IDL provides the standard interface between objects, and is the base mechanism for object interaction. The Object Management Group's CORBA 1.1 (Common Object Request Broker Architecture) specifies the interface between objects. IDL (Interface Definition Language) is the base mechanism for object interaction. The SunSoft OMG IDL CFE (Compiler Front End) version 1.2 provides a complete framework for building CORBA 1.1-compliant preprocessors for OMG IDL. To use it you write a back-end. A complete compiler of IDL would translate IDL into client side and server side routines for remote communication in the same manner as Sun's current RPCL compiler. The IDL compiler front end allows integration of new back ends which can translate IDL to various programming languages. Several companies including Sunsoft are building back ends to the CFE which translate IDL into target languages, e.g. Pascal or C++, in the context of planned CORBA-compliant products. IDL requires C++ 2.1. Not to be confused with any of the other IDLs. E-mail: <[email protected]>. Telephone: Mache Creeger, SunSoft, Inc. +1 (415) 336 5884.
- kernel user interface package — (tool) (KUIP) The human interface to Physics Analysis Workbench (PAW).
- length between perpendiculars — the length of a hull between the forward and after perpendicular. Compare perpendicular (def 11).
- longitudinal redundancy check — (storage, communications) (LRC, Block Redundancy Check) An error checking method that generates a longitudinal parity byte from a specified string or block of bytes on a longitudinal track. The longitudinal parity byte is created by placing individual bytes of a string in a two-dimensional array and performing a Vertical Redundancy Check vertically and horizontally on the array, creating an extra byte. This is an improvement over the VRC because it will catch two errors in the individual characters of the string, beyond the odd errors.
- lotus development corporation — (company) A software company who produced Lotus 1-2-3, the Symphony spreadsheet and Lotus Notes for the IBM PC. Disliked by the League for Programming Freedom on account of their lawsuits. Quarterly sales $224M, profits $10M (Aug 1994). Telephone: +1 (617) 225 1284.
- man that corrupted hadleyburg — a short story (1900) by Mark Twain.

- mecklenburg-western pomerania — a state in NE Germany. 8842 sq. mi. (22,900 sq. km). Capital: Schwerin.
- modified frequency modulation — (storage) (MFM, Modified FM, or sometimes "Multiple Frequency Modulation") A modification to the original frequency modulation scheme for encoding data on magnetic disks. MFM allows more than 1 symbol per flux transition (up to 3), giving greater density of data. It is used with a data rate of between 250-500 kbit/s on industry standard 3.5" and 5.25" low and high density diskettes, and up to 5 Mbit/s on ST-506 hard disks. Except for 1.44 MB floppy disks, this encoding is obsolete. Other data encoding schemes include GCR, FM, RLL. See also: PRML.
- mordovian autonomous republic — an autonomous republic in the Russian Federation in Europe. 9843 sq. mi. (25,493 sq. km). Capital: Saransk.
- multics relational data store — (database) (MRDS) The first commercial relational database, implemented as part of Multics by Jim Weeldreyer and Oris Friesen of Honeywell Phoenix in about 1977. MRDS included a report writer called LINUS written by Jim Falksen.
- multimedia messaging services — (messaging) (MMS) A feature of some mobile telephones that allows them to send messages including text, sound, images and video.
- multiprotocol label switching — (networking) (MPLS) A packet switching protocol developed by the IETF. Initially developed to improve switching speed, other benefits are now seen as being more important. MPLS adds a 32-bit label to each packet to improve network efficiency and to enable routers to direct packets along predefined routes in accordance with the required quality of service. The label is added when the packet enters the MPLS network, and is based on an analysis of the packet header. The label contains information on the route along which the packet may travel, and the forwarding equivalence class (FEC) of the packet. Packets with the same FEC are routed through the network in the same way. Routers make forwarding decisions based purely on the contents of the label. This simplifies the work done by the router, leading to an increase in speed. At each router, the label is replaced with a new label, which tells the next router how to forward the packet. The label is removed when the packet leaves the MPLS network. Modern ASIC-based routers can look up routes fast enough to make the speed increase less important. However, MPLS still has some benefits. The use of FECs allows QoS levels to be guaranteed, and MPLS allows IP tunnels to be created through a network, so that VPNs can be implemented without encryption.
- nuclear regulatory commission — an independent agency, created in 1975, that licenses and regulates the nonmilitary use of nuclear energy. Abbreviation: NRC.
