Index

This website is structured as a Zettelkasten, so there's a mix of many pages, long and short, polished and rough drafts, that can be explored alphabetically or ordered by keyword or by the date they where created.

Good starting points are the Generative Art collection and some attempts at Implementing Programming Languages or performing computation on unusual machinery.

One of my more esoteric favorites is Desert of the Real , a small game implemented in HyperCard , including an editor for Quadtree Grammars used to create level backgrounds.

I use the Emacs editor and maintain Org Flashcards , a spaced repetition system for Org Mode . Org Zettelkasten collects some code I use to manage and navigate a collection of .org files like the one this website is based on.

The Changelog is structured more like a conventional blog and tracks changes made to the content of this website. To be notified on updates, you can subscribe to the Changelog Feed .

I've written a wrapper around Donald Knuth's dlx1.c implementation of an exact-cover solver to use it from Python and started collecting some patterns for expressing more flexible constraints as equivalent exact-cover problems.

Equality by Exact Cover explores how integer equality can be expressed as an exact-cover problem, and Tiling Grids with (Directed) Loops uses the solver to fill a 2D grid with directed loops.

Regular Languages in Neo4j and Cypher explores how nondeterministic finite automata can be represented as graphs, and how path patterns can be used to find words in the regular languages accepted by these automata.

There's now a Changelog keeping track of how the content of this website changes over time.

I've rewritten the Index page to longer paragraphs and removed some unfinished or very short pages. If something went missing along the way, please let me know!

Simulating Slime Mold has some pretty images that don't look like slime mold at all.
