  • 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.
  • data flow analysis — (programming)   A process to discover the dependencies between different data items manipulated by a program. The order of execution in a data driven language is determined solely by the data dependencies. For example, given the equations 1. X = A + B 2. B = 2 + 2 3. A = 3 + 4 a data-flow analysis would find that 2 and 3 must be evaluated before 1. Since there are no data dependencies between 2 and 3, they may be evaluated in any order, including in parallel. This technique is implemented in hardware in some pipelined processors with multiple functional units. It allows instructions to be executed as soon as their inputs are available, independent of the original program order.
