I'm working on an emulator for 16-bit computer I have designed for teaching students. It's designed to make low level computing more accessible for modern students by making things as visual as possible, for example blinken-lighten for the registers like w/ the old PDPs, color coded memory that shows where the code and data segments are, where the stack is, etc, and a small frame buffer that drives a 64x64 2 bit display that uses the same color palette as the original gameboy. The instruction set is a mashup of MIPS, the Scott CPU and JVM/forth stack operations. I'm excited about it.

here's a screenshot:

I'm working on adding something like https://graphtoy.com/ to my lisp-based 3D art tool https://bauble.studio/. It's really useful to visualize functions like this, especially when writing animation curves that vary over time.

It's easy to add it as a plain overlay over the screen if you're graphing a function, but I really want it to be able to plot arbitrary expressions with free variables where it just infers the axes, so you can just see values overload in the orthographic view (press alt-q to see that). That way you can just write something like (ss p.x 0 10 | graph) on any expression and visualize it as you go. I haven't quite figured out how to make it seamless though...

What happens if you combine a full Dungeons & Dragons rules engine with an LLM to act as the dungeon master? Until the recent wave of reasoning models, the answer was mostly 'nothing coherent', but Claude 3.7 with thinking is very good at this! It will probably get rate limited with minimal traffic, but I have a demo up at https://lairsandllamas.com

I'm porting a Chip-8 interpreter I wrote in Ruby to C. I was planning to do it in Rust but thought it would be good to face the problems Rust is solving first.

Considering quitting my mind-melting corporate job to have the freedom of mind to pursue another attempt of starting my own business. So the decision is, what I'm working on. Background: they announced large scale restructurings last week and that could be my chance of getting some money for leaving (region beta paradox in full swing here).

Anyone else?

Rebuilding my personal website. A friend had bought me a .su domain (since my card can't buy online) but he disappeared years ago.

So I'm updating it and putting it back online!

I'm working on a parody of the lofi hip-hop radio YouTube streams, but for Byzantine music (chanting) of the Eastern Orthodox Church.

The end goal is a community-focused study/prayer/chill sound generator for an Orthodox Christian audience

I'm working on MindRoot, which is a plugin-focused agent framework with a fully customizable chat UI and swappable services and commands as well as pipes, agents and personas. The goal is to be fully user-friendly while also easily expandable for programmers. And to make it easy to share tool commands and agents. Hopefully someday with a public plugin+agent+persona registry built in.
