Extreme TLDR:
Dave Gauer explores Forth, a programming language by Chuck Moore, known for its simplicity and flexibility, invoking memories of Usenet and its folklore. Forth’s unique features include Reverse Polish Notation (RPN), stack-based operations, and concatenative programming, allowing seamless manipulation of data without explicit named variables. Gauer contrasts applicative programming with the concise, sequential nature of concatenative languages like Joy, emphasizing the power of combinators in creating higher-order functions and achieving universal computation with minimal constructs like S and K.
