I’m working on a video game, purely for fun. Here is a work in progress build: https://muffinman-io.itch.io/space-deck-x It is a combination of a shoot-em-up and deck building. You fly and shoot until you get to the boss, when you get your deck out to fight them. That genre combination is definitely too ambitious, but I think it is fun to play and I’m enjoying making it. I have a bunch of ideas how to combine the two…

i wish i was that good at pixel art, it would be my sole hoby if i were

Trying to make my Rust library `composable-indexes` more ergonomic. It is for indexing a collection on multiple dimensions in a type-safe and composable manner.

In other words, something safer & more concise than maintaining multiple HashMap's, but a lot less involved & simpler than an in-memory SQLite.

It's better explained by the example here: https://github.com/utdemir/composable-indexes/blob/3baa36762....

For a fun project; rejuvenating a 1978 Chess Engine https://github.com/billforsternz/zargon. It's the second time I've worked on the same engine. The first time I got it working nicely on modern machines, running four orders of magnitude faster than in in 1978. This time I hope to get it running much faster than that. I found a bug in the 1978 Z80 assembly the other day. A blog post "Fixing a 50 year old bug..." or similar suggests itself.

The stack has grown and almost shrunk again.

* The immediate-mode "every tick I ask you for a VDOM based on the user-defined state" TUI framework has all the fundamental features, I think; writing docs and expanding the library of components it ships with. https://github.com/Smaug123/WoofWare.Zoomies

* Decided I needed a nice text display widget, so got side-tracked into implementing the Knuth-Plass paragraph layout algorithm; it currently functions but is buggy. https://github.com/Smaug123/WoofWare.KnuthPlass

* Finally starting to put proper effort into the LLM integrations into my workflows, writing skills, defining the Gospel According To Me to try and poke the LLMs into the right basin - with limited success so far. https://github.com/Smaug123/gospel

No progress on the deterministic .NET runtime.

Making a first aid kit for stingray stings! If there are lifeguards nearby they’ll usually treat you, but we think it would be nice to have a “go bag” in the back of your car for scenarios where there aren’t lifeguards (remote beaches, or after sunset, etc). The standard of care is to clean the wound and submerge it in water around 110-120F for 1-2 hours. We’ve been researching the best, safest method to get that heat, and working on putting a package together. Here’s our first attempt:

I'm working on a hardware/software utility to play Switch/Switch 2 games remotely with my brothers. I found a way to emulate a Switch Pro Controller using a Raspberry Pi Pico based on several different sources (look in the README for more info). I used that to write a firmware for the Pico (with the help of GPT Codex 5.1).

Then I wrote a Python program that connects whatever controller my brothers want to use (as long as it's supported by SDL2.0) and forwards that data from their computer, through Parsec, through a USB-UART adapter, to the Pico, then to the Switch. I then have a low latency capture card (Magewell Pro Dual HDMI I got off of ebay for $100) forwarding the video and audio from the Switch to my PC which I share to my brothers via Parsec. The audio was a bit tricky to get right, and ended up having to use a Virtual audio cable and Voicemeeter potato (a software audio mixer) so that both myself and my brothers could hear the audio.

It works surprisingly well and the latency is pretty low. I even got rumble working! (but not motion controls. If anyone wants to attempt it, I will accept PRs). I haven't done any formal benchmarking for performance, but my brothers and I were able to play Smash Ultimate without too much bother about latency.

You could also use the accessory Python library I made to automate switch controller presses (look in the examples directory). Might be useful for TAS speedruns?

The project is here for anyone interested. It's a bit rough and needs some cleanup and maybe a video tutorial on remote setup. But here is the WIP:

https://ShipmentPlanner.com It"s a tool to help shipping goods to warehouses for ecommerce (amazon) sellers.

Just made a landing page and then transfered its style to the app using Claude AI. Was so impressed that I paid for a supscription immediately.

Will polish the app and plan to launch next month.
