An optical laser works by bouncing photons back and forth between two mirrors, one totally reflective and one partially reflective. If the lasing material (usually a crystal) has the right properties, photons scattering off the atoms in the crystal will excite cascades of more photons, all in lockstep. Eventually the beam will escape through the partially reflective mirror.
One kind of sorcerer’s apprentice mode involving bounce messages can produce closely analogous results, with a cascade of messages escaping to flood nearby systems. By mid-1993 there had been at least two publicised incidents of this kind.

legal Software may, under various circumstances and in various countries, be restricted by patent or copyright or both. Most commercial software is sold under some kind of software license. A patent normally covers the design of something with a function such as a machine or process. Copyright restricts the right to make and distribute copies […]

- Software methodology
programming The study of how to navigate through each phase of the software process model (determining data, control, or uses hierarchies, partitioning functions, and allocating requirements) and how to represent phase products (structure charts, stimulus-response threads, and state transition diagrams).
