SECD machine

The SECD machine is a highly influential (see: ) virtual machine and abstract machine intended as a target for functional programming language compilers. The letters stand for Stack, Environment, Control, Dump—the internal registers of the machine. The registers Stack, Control, and Dump point to (some realisations of) stacks, and Environment points to (some realisation of) an associative array. The machine was the first to be specifically designed to evaluate lambda calculus expressions. It was originally described by Peter J. Landin in "The Mechanical Evaluation of Expressions" in 1964. The description published by Landin was fairly abstract, and left many implementation choices open (like an operational semantics). Lispkit Lisp was an influential compiler based on the SECD machine, and the SECD machine has been used as the target for other systems such as Lisp/370. In 1989 researchers at the University of Calgary worked on a hardware implementation of the machine. (Wikipedia).

RubyConf 2021 - Programming with Something by Tom Stuart

Programs which manipulate other programs are extremely fun and incredibly powerful. To write them, we need a way to represent code as a data structure which we can analyse, manipulate and eventually execute. In this talk we’ll learn how to store executable code as data in Ruby, and explore

TDD Is The Best Design Technique

Test Driven Development is one of the most profound ways to improve the quality of your code. This is not just in the simplistic sense of “we tested it works” but also the way that testing very strongly encourages us, if not forces us, to create testable code, and the hallmarks of testab
