John's absolutely worth supporting. Throw a few dollars his way; his contributions to emacs and elisp are worth it alone.
Also accepting help through Patreon, if that is preferred. This goes toward work on Emacs Lisp and Ledger, primarily, but also with many of my Haskell, Coq, Rust and Python work:.

Fretting about -- and optimising too heavily in an attempt to cut down on -- LLM token spend feels like a 2025 and probably a 2026 problem. The cost seems to follow some sort of Moore's law; will it really be a huge problem in a few years at this rate?.

I've used Chakra for a react project, and I'm giving mantine a shot this time around. So far it's very impressive.

3d printers are amazing. I have a desktop tool capable of fabricating stuff out of 'thin air' from rolls of plastic filament and a little CAD modelling. What a wonderfully futuristic world we live in today.

Tree-sitter makes it a easier to build bulk editing tooling in #emacs. I've been improving Combobulate's bulk edit tooling a lot recently and I figured I'd write about how it works and some of the challenges that sprung up.

Combobulate's long had the ability to bulk edit matches using the multiple cursors package, but building seamless and useful bulk editing tooling is not as straightforward as it seems. And what if...

What's the best way to showcase what a code refactoring operation using #emacs tree-sitter does before you commit to it? And what do you do when there's more than one tree node to choose from?.

Editing code using a concrete syntax tree may seem straightforward, but it's a complex task fraught with challenges. For every command that modifies the code, there's ample room for ambiguity. What...
