“Malbolge, invented by Ben Olmstead in 1998, is an esoteric programming language designed to be as difficult to program in as possible. The first ‘Hello, world!’ program written in it was produced by a Lisp program using a local beam search of the space of all possible programs. It is modeled as a virtual machine based on ternary digits.” [. . .]
“The language is named after ‘Malebolge,’ the eighth level of hell in Dante’s Inferno, which is reserved for perpetrators of fraud. The actual spelling ‘Malbolge’ is also used for the sixth hell in the Dungeons and Dragons roleplaying game.” —Wikipedia
