Without this, ILM could never have bought into Python so heavily for its mission-critical production process. One case where access to source has already been beneficial was in ILM's continued use of Python 1.4, which is generally considered obsolete.

Threads are used to simultaneously monitor the production process, watch events from the GUI, and detect error messages coming in from other parts of the machine. The digital I/O interface and RS-485 serial communicator were libraries written in C. SWIG was used to quickly make these callable from Python code. The GUI components ...

There's considerable literature on graph algorithms, which are an important part of discrete mathematics. Graphs also have much practical use in computer algorithms. Obvious examples can be found in the management of networks, but examples abound in many other areas. For instance, caller-callee relationships in a computer progra...
