deep magic definition
[possibly from C. S. Lewis's "Narnia" books] An awesomely arcane technique central to a program or system, especially one neither generally published nor available to hackers at large (compare
black art); one that could only have been composed by a true
wizard. Compiler optimisation techniques and many aspects of
OS design used to be
deep magic; many techniques in cryptography, signal processing, graphics, and AI still are. Compare
heavy wizardry. Especially found in comments of the form "Deep magic begins here.". Compare
voodoo programming.
