  • mengistu haile mariam — born 1937, Ethiopian political leader: head of state 1977–87; president 1987–91.
  • model-view-controller — (programming)   (MVC) A way of partitioning the design of interactive software; a software architecture pattern. The "model" is the internal workings of the program (the data objects and algorithms), the "view" is how the user sees the state of the model and the "controller" is how the user changes the state or provides input. MVC was the original kind of what is now sometimes called an MV* pattern. Trygve Reenskaug introduced it into Smalltalk-76 while visiting Xerox PARC in the 1970s.
  • multi-level marketing — Multi-level marketing is a marketing technique which involves people buying a product, then earning a commission by selling it to their friends. The abbreviation MLM is also used.

  • narrow-angle glaucoma — Ophthalmology. angle-closure glaucoma. See under glaucoma.
  • negotiable instrument — order or promise to pay money
  • negotiable securities — securities that are legally transferable in title from one party to another
  • nightmare file system — Pejorative hackerism for Sun's Network File System (NFS). In any nontrivial network of Suns where there is a lot of NFS cross-mounting, when one Sun goes down, the others often freeze up. Some machine tries to access the down one, and (getting no response) repeats indefinitely. This causes it to appear dead to some messages (what is actually happening is that it is locked up in what should have been a brief excursion to a higher spl level). Then another machine tries to reach either the down machine or the pseudo-down machine, and itself becomes pseudo-down. The first machine to discover the down one is now trying both to access the down one and to respond to the pseudo-down one, so it is even harder to reach. This situation snowballs very quickly, and soon the entire network of machines is frozen - worst of all, the user can't even abort the file access that started the problem! Many of NFS's problems are excused by partisans as being an inevitable result of its statelessness, which is held to be a great feature (critics, of course, call it a great misfeature). ITS partisans are apt to cite this as proof of Unix's alleged bogosity; ITS had a working NFS-like shared file system with none of these problems in the early 1970s. See also broadcast storm.

  • packed encoding rules — (protocol, standard)   (PER) ASN.1 encoding rules for producing a compact transfer syntax for data structures described in ASN.1, defined in 1994. PER provides a much more compact encoding then BER. It tries to represents the data units using the minimum number of bits. The compactness requires that the decoder knows the complete abstract syntax of the data structure to be decoded, however. Documents: ITU-T X.691, ISO 8825-2.
  • payload assist module — a U.S. solid-propellant rocket used to boost a medium-weight spacecraft from a circular low-earth orbit to an elliptical transfer orbit for later insertion into a geosynchronous orbit. Abbreviation: PAM.
  • peephole optimisation — (compiler)   A kind of low-level code optimisation that considers only a few adjacent machine code instructions at a time and looks for certain combinations which can be replaced with more efficient sequences. E.g. ADD R0, #1 ADD R0, #1 (add one to register R0) could be replaced by ADD R0, #2 as long as there were no jumps to the second instruction.
  • peephole optimization — peephole optimisation
  • pentamethylenediamine — cadaverine.
  • philadelphia scrapple — a superior variety of scrapple made with pork shoulder and other cuts of pork rather than with pork scraps.
  • photoelectric current — photocurrent.
  • phrase-structure rule — a rule that generates a sentence or other syntactic construction from words and phrases and identifies its constituent structure.
  • physically challenged — See example at challenged (def 1).
  • picture quality scale — (graphics)   (PQS) A system for rating image quality based upon features of images that affect their perception by the human eye, rather than the traditional signal-to-noise ratio which examines differences for every single pixel.
  • piezoelectric ceramic — any ceramic that exhibits piezoelectric properties.
  • piezoelectric crystal — a crystal, such as quartz, that produces a potential difference across its opposite faces when under mechanical stress
  • play russian roulette — take a foolish risk
  • portable commodore 64 — (computer)   A version of the Commodore 64 modelled after the original Osborne portable PCs, with a flip-down keyboard that revealed a 5-inch colour monitor, and a built-in 1541 floppy disk drive. It is thought that few were made but that they did go on sale, at least in Canada.
  • portable common loops — (PCL) A language which started out as an implementation of CommonLoops and turned into a portable CLOS implementation. Version 1992-08-28. It runs under Lucid Common LISP 4.0.1 and CMU Common LISP 16e.

  • primitive dicotyledon — any living relative of early angiosperms that branched off before the evolution of monocotyledons and eudicotyledons. The group comprises about 5 per cent of the world's plants
