Tree Sitter - Growing Trees in Concrete

I just ran into this by accident: https://tree-sitter.github.io/tree-sitter/. I learned about it from this old project https://github.com/stonebuddha/vscode-better-sml. This thing is just a blob of webasm code and some configuration files. It's a joke: it's all up-side-down! See Language Server Protocol: 

The Language Server Protocol (LSP) is an open, JSON-RPC-based protocol for use between source-code editors or integrated development environments (IDEs) and servers that provide "language intelligence tools": programming language-specific features like code completion, syntax highlighting and marking of warnings and errors, as well as refactoring routines. The goal of the protocol is to allow programming language support to be implemented and distributed independently of any given editor or IDE. In the early 2020s, LSP quickly became a "norm" for language intelligence tools providers.

It's concrete all the way down. Why? Is it something to do with security? Whose security? Microsoft's?

Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited.

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...
