My side project is now codebase explainability. I basically don't buy the premise that we just have to give up on comprehension as code generation scales; I just think that text is too limited by itself. So going a step deeper than asking Claudex "teach me this project", but having it produce a navigable snapshot of what's going on. Big bang prototypes have been pretty awful, even after feeding the LLMs huge document…

I posted about my project below - https://github.com/0x007BA7/codebook

But maybe you should checkout the tools it’s based on, sem - https://github.com/Ataraxy-Labs/sem and ultimately treesitter. They at least give a more structured approach to dealing with code than simple text.

building https://shellular.dev, an app that let's you use your dev env from anywhere - your agents (Claude Code, Codex. OpenCode, Pi etc.), persistent terminals, local repos and code editor, in-app browser to remotely access localhost: and js console for debugging.

Code World Models in Simultaneous Move settings like Capital Markets. DeepMind's CWM approach relies on standard MCTS/IS-MCTS, which assumes a single active player at each node.

This doesn't work in simultaneous-move settings like Orbit Wars (or order-book markets), converging to an exploitable pure strategy rather than a Nash equilibrium.

LeCun's JEPA, by contrast, is a learned neural world model, which lacks the determinism, speed, and debuggability of a code-based simulator. Thus, it can drift or predict illegal states, and you can't inspect why it made a prediction the way you can trace a Python function.

TL;DR: The benefit is better auditability and easier RL-like training. The SM-MCTS extension fixes the first problem (decoupled UCB per player approximates Nash equilibrium instead of a pure strategy) while keeping the second advantage intact (a deterministic, inspectable code simulator).

Photos Wallpaper - recreates the functionality from older Mac OS versions to rotate photos from your library as wallpaper, changing on a schedule.

Written by Codex with me driving product direction, reviewing, testing, occasionally scolding, and handling the release process.

Accepted onto the Mac App Store last week.

I struggle with terminology so I made a little Gnome utility for easier LLM-based terminology lookups from a highlighted word/term + contextual screenshot. So far it's working pretty well, kinda like a better version of the Mac OS or Kindle ones.

For the life of me, I could never get electronics. I used to love the idea of me coming up with electronic circuit designs, but the arcane art of electronics never really clicked for me because I just couldn't intuitively grasp the maths no matter which book I read (AoE, I'm looking at you). But then it hit me, I don't need maths, I just need a formal language to represent the circuits. So over the past few weeks, I worked on a code your own spice (the electronic simulator). So now, for the first time in history, I finally understand how circuits work and how they are designed. And I did this all by coding circuits in python and making my own functional spice (which used to seem impossible at one point, it's surprising how easy it is though).

This month has mostly been personal website. Serious warning - style is an HN ripoff atm, forgive me in advance. Will change in the future to something original or minimal.

Migrated my beverages app from notion to an actual webapp my wife and I can use: https://stefanludlow.com/beverages/

Built a bunch of slime mold art: https://stefanludlow.com/art/foraging-network

Project I've got in progress is a migration of the old DIKU mud engine from C to Rust and making a Moog Model D synth recreation in rust with a JS wrapper.
