i'm building a common lisp operating system capable of diverse double compilation and booting a raspberry pi. well, claude is: https://modus-lisp.github.io

Amazing how concise the code is! There is something about Lisp that feels very pure and ethereal.

QuickMDSim - An easy way to run molecular simulations in the cloud: https://quickmdsim.com

This simplifies the setup for researchers who want to simulate materials science problems like battery electrode performance on GPUs with a simple usage-based pricing model instead of traditional HPC

Started a few different things:

1. A robotics information and news website. Any feedback is appreciated. https://robotica.dev/

2. Applied DBSP theory to Postgres https://github.com/getravi/pg_dbsp and DuckDB https://github.com/getravi/duckDBSP. The idea is to have incrementally maintained materialized views.

I’ve been working on https://computeprices.com for almost 2 years.

My goal is to better understand the economics of AI and make something useful in the process.

(Coming soon: kWh prices and robot prices)

Mostly built with claude code with a dash of codex.

A recent, useful unlock in the process has been a daily CC routine to check the health of the 53 price collectors in the project.

Because my work life is mostly LLM promoting, I’ve gotten back into hobby robotics, which I think has a low chance of LLMs taking over anytime soon. Designing and building a robot that can build a wooden hardwood deck using the edge-screw method.

I’m building a website for discovering first names that’s enjoyable to explore: https://abracadanames.com It started with a family member telling me they were frustrated with existing websites. What I noticed is that in many cases they feel cluttered and not smooth to use, almost like a 1-to-1 translation of the underlying database queries, where they have you choose filters and sorting options upfront then browse th…

Looks really good. If you post on HN I will upvote

I'm working on https://pushrealm.com the AI-first knowledge sharing network. Think StackOverflow for bots. It works like this: - When your agent is stuck on a bleeding edge issue, search Push Realm first for a solution. - If you find a solution, your agent can mark it as successful to help surface the solution to others (and hopefully save fruitlessly burning more tokens) - Can't find a solution? Post an open problem…

Stackoverflow is permissively licensed nowadays.. What about the content on your network?

I'm working on building open source control firmware that runs on the Masterbuilt Gravity series electronically controlled charcoal smokers.

https://gitlab.com/prbs23/freefall_800

The smoker hardware itself is pretty good, but like most IoT devices, the firmware and app sucked. So I reverse engineered the whole control PCB, and have been rebuilding new open source firmware from scratch. All the basic functionality is working now with a fully local control web app. Plus an Andoid app, and Home Assistant integration.

Currently working on interface refinements, and some more advanced control sequencing features.

I wrote up all the reverse engineering details in a blog post here: https://www.prbs23.com/blog/posts/reverse-engineering-gravit...
