Building a Quine from Kleene's Second Recursion Theorem

Original: Constructing a Quine from Kleene's Second Recursion Theorem

A new technical article walks through how to construct a quine — a program that prints its own source code — directly from Kleene's second recursion theorem. The piece connects a classic result in computability theory to a well-known programming curiosity, showing how self-reference in programs follows formally from the theorem. Readers interested in theoretical computer science are discussing the exposition and its worked derivation.

Why now: Programmers and theorists enjoy seeing abstract recursion theory yield a concrete, self-reproducing program.
