Zainab Ali - Recursion Schemes from First Principles

This is about a paper published in 1991: Functional programming with bananas, lenses, envelopes and barbed wire by Erik Meijer, Maarten Fokkinga & Ross Paterson. Other references to articles and papers by Milewski, Wadler and Gibbons at 32:48. I also came across this paper by Wadler: The Girard-Reynolds Isomorphism.

I wish I had known about this, it would have saved me several years of work! Mike Gordon presumably didn't know about it either: see Emily Riehl and Terrence Tau on The Future of Mathematics.

Steven Johnson - So You Think You Know How to Take Derivatives?

A derivative is linearisation, and differential calculus is essentially linear algebra, ...  See  Freya Holmér - Why Can't You Multiply Vectors?  and  Freya Holmér on Continuity of Splines . See also the MIT OCW page:  Matrix Calculus For Machine Learning And Beyond  (Alan Edelman, Steven G. Johnson) Subscribe to The Julia Programming Language . Alan Edelman talking about expressing mathematics as computer code. The idea is that you can use computer languages to communicate mathematical ideas precisely to other people.

Hitachi HD44780U LCD Display Fonts

I finally got the bit-mapped fonts from the Hitachi "1602" display :  Here's some JavaScript: const HD44780U01ASCII=[ [],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[], [],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ], [4, 4, 4, 4, 0, 0, 4, 0, 0, 0, ], [10, 10, 10, 0, 0, 0, 0, 0, 0, 0, ], [10, 10, 31, 10, 31, 10, 10, 0, 0, 0, ], [4, 15, 20, 14, 5, 30, 4, 0, 0, 0, ], [24, 25, 2, 4, 8, 19, 3, 0, 0, 0, ], [12, 18, 20, 8, 21, 18, 13, 0, 0, 0, ], [12, 4, 8, 0, 0, 0, 0, 0, 0, 0, ], [2, 4, 8, 8, 8, 4, 2, 0, 0, 0, ], [8, 4, 2, 2, 2, 4, 8, 0, 0, 0, ], [0, 4, 21, 14, 21, 4, 0, 0, 0, 0, ], [0, 4, 4, 31, 4, 4, 0, 0, 0, 0, ], [0, 0, 0, 0, 12, 4, 8, 0, 0, 0, ], [0, 0, 0, 31, 0, 0, 0, 0, 0, 0, ], [0, 0, 0, 0, 0, 12, 12, 0, 0, 0, ], [0, 1, 2, 4, 8, 16, 0, 0, 0, 0, ], [14, 17, 19, 21, 25, 17, 14, 0, 0, 0, ], [4, 12, 4, 4, 4, 4, 14, 0, 0, 0, ], [14, 17, 1, 2, 4, 8, 31, 0, 0, 0, ], [31, 2, 4, 2, 1, 17, 14, 0, 0, 0, ], [2, 6, 10, 18, 31, 2, 2, 0, 0,...

Using Pipewire to Make A Music Synthesizer

Illustration from Project Gutenberg's The Tenniel Illustrations for Carroll's Alice in Wonderland by Sir John Tenniel. Thinking about the linux desktop audio problem: I'm not the only one who finds this weird: https://t.co/b2BZMiak07 — eternal Doorman (@IanANGrant66) May 17, 2025  I noticed that if you change the volume using the Gnome volume keys it changes it in jumps. Usually you don't notice, but if you play a pure sine tone then you can easily hear the distortion. If you want to play with pipewire from C on Ubuntu 24.04 then it's really easy. The pipewire tutorials and examples can be compiled and run if you just first install the pipewire-0.3-dev package with sudo apt install libpipewire-0.3-dev But the API is sooo far away from pluggable, typed streams that I find it quite depressing. Is it because nobody understands the necessary type system . See  Programming Channel Processes and Alice's Adventures In The Wonderland Wide Web . [Update: y...
