SIOD
Scheme In One Defun, or humorously Scheme In One Day (SIOD) is a programming language, a dialect of the language Lisp, a small-size implementation of the dialect Scheme, written in C and designed to be embedded inside C programs. It is notable for being perhaps the smallest practical implementation of a Lisp-like language. It was written by George J. Carrette originally. It is free and open-source software released under a GNU Lesser General Public License (LGPL).

Features
SIOD features include:
- Implements the original version of Scheme from the Lambda Papers, but none of the modern language standards.
- Represents a very early use of conservative garbage collection in a Lisp interpreter, a method later copied by SCM and Guile.
- Compiling is implemented by emitting a fixed machine code prologue followed by a fast-loading binary representation of the parse tree to be interpreted.
Applications
- GNU Image Manipulation Program (GIMP) – SIOD was its primary extension language, Script-Fu, until GIMP 2.4 was released.[1]
- Siag Office – Scheme in a Grid (SIAG) is a spreadsheet application using SIOD as a base.
- Festival Speech Synthesis System – SIOD is its underlying command interpreter.[2]

gollark: Fascinating.
gollark: This is why AMD was basically irrelevant for many years until Zen back in 2017 or so.
gollark: Each pair of "cores" shares a bunch of resources, so it isn't really as fast as an actual "core" in other designs, and I think their IPC was quite bad too, so the moderately high clocks didn't do very much except burn power.
gollark: See, while the FX-4100 is allegedly a fairly high-clocked quad-core, this is misleading. AMD's Bulldozer architecture used "clustered multithreading", instead of the "simultaneous multithreading" on modern architectures and also Intel's ones at the time.
