  • connected subgraph — (mathematics)   A connected graph consisting of a subset of the nodes and edges of some other graph.
  • considered harmful — (programming, humour)   A type of phrase based on the title of Edsger W. Dijkstra's famous note in the March 1968 Communications of the ACM, "Goto Statement Considered Harmful", which fired the first salvo in the structured programming wars. Amusingly, the ACM considered the resulting acrimony sufficiently harmful that it will (by policy) no longer print articles taking so assertive a position against a coding practice. In the ensuing decades, a large number of both serious papers and parodies bore titles of the form "X considered Y". The structured-programming wars eventually blew over with the realisation that both sides were wrong, but use of such titles has remained as a persistent minor in-joke.

  • daisywheel printer — (printer)   A kind of impact printer where the characters are arranged on the ends of the spokes of a wheel (resembling the petals on a daisy). The wheel (usually made of plastic) is rotated to select the character to print and then an electrically operated hammer mechanism bends the selected spoke forward slightly, sandwiching an ink ribbon between the character and the paper, as in a typewriter. One advantage of this arrangement over that of a typewriter is that different wheels may be inserted to produce different typefaces.

  • demorgan's theorem — (logic)   A logical theorem which states that the complement of a conjunction is the disjunction of the complements or vice versa. In symbols: not (x and y) = (not x) or (not y) not (x or y) = (not x) and (not y) E.g. if it is not the case that I am tall and thin then I am either short or fat (or both). The theorem can be extended to combinations of more than two terms in the obvious way. The same laws also apply to sets, replacing logical complement with set complement, conjunction ("and") with set intersection, and disjunction ("or") with set union. A (C) programmer might use this to re-write if (!foo && !bar) ... as if (!(foo || bar)) ... thus saving one operator application (though an optimising compiler should do the same, leaving the programmer free to use whichever form seemed clearest).
