I knew about Donald Knuth's  "TeX, the program" and David R. Hanson's "lcc, A Retargetable C Compiler: Design and Implementation", "C Interfaces and Implementations: Techniques for Creating Reusable Software", but not about "pbrt, Physically Based Rendering: From Theory to Implementation" by Matt Pharr, Wenzel Jakob, Greg Humphreys http://pbrt.org/ and "lguest, A lightweight x86 virtual machine monitor for Linux" by Rusty Russell https://swtch.com/lguest/

Literate emacs initialisation file. Found on
https://www.reddit.com/r/emacs/comments/tgrs5g/emacs_as_a_universal_frontend_interface/
which in turn was mentioned by Sacha Chua on https://sachachua.com/blog/2022/03/2022-03-21-emacs-news/

Fileworthy is intended to facilitate easy management of files and notes across many devices.

The articles sound interesting, particularly those about Plan 9.
So does TexiWeb Jr., a super simple literate programming system built on top of Texinfo and implemented in awk https://github.com/arnoldrobbins/texiwebjr
which is mentioned in
AWK As A Major Systems Programming Language — Revisited

struct --- Convert Fortran into Ratfor
could be useful for proot:
This is Brenda Baker's struct program. It converts plain old Fortran into Rational Fortran (ratfor). The code here is taken from the TUHS archives, starting with the V7 version, and progressing through V8 and V10.

I read Literate Configuration by Diego Zamboni. Now I want to replace my Dotbot-managed dotfiles with an Org file.

Found via https://genehack.blog/2020/04/meta-post/
where https://randomgeekery.org/tags/indieweb/ was mentioned.

This is an Emacs configuration file written in Org mode. It is an attempt to keep ~/.emacs.d tidy, but still be able to keep it all in one file. Contains brief explanations of the configurations.

The "tangle" piece was successfully bootstrapped on November 4, 2013.
The "weave" piece started producing a reasonable-looking document
on November 11, 2013.

As of Fri Feb 19 12:07:09 IST 2016, both the source code and literate programming document
are licensed under the GNU GPL. See the file COPYING.

Other repositories from the same author are interesting too: e.g.
the portable C compiler

and a converter from RCS to git

Exploratory programming environment and documentation generator for Common Lisp.

Just what it says. The tool LP/Lisp will be presented at the international lisp conference (ILC2010, http://www.international-lisp-conference.org).
