The core features of this tunneling tool are stable. I am working on adding support for TCP as well as UDP traffic through the same tunnel.

Local asr/stt on mlx for apple silicon based on Facebook omnilingual model that was just released. Used Claude to port model weights from PyTorch to mlx (that was exciting, claude can do that).

Residential solar PV+ESS w/net metering. Rushing to finish connecting it all for inspection on tuesday... if I'm lucky and get commissioned this year I can get the last federal tax incentives. Fingers crossed

A few games developed entirely with AI. I'm using GitHub CoPilot to drive the development, and I'm having the AI come up with the graphics programmatically as well. It's a pretty fun project.

Since getting laid off in May and failing to find any jobs for ML in healthcare, I am working with a friend I met during my MPH to start a boutique consultancy to help hospitals deploy AI / health technology.

I'm working on Mizu, a small Go web framework built around a simple idea: net/http is already good, frameworks should not fight it.

I've kept running into the same problems in popular Go frameworks: hidden context mutation, magic middleware ordering, reflection-heavy binding, and APIs that slowly drift away from the standard library. The Gin ecosystem in particular has accumulated a lot of technical debt and footguns, which this post summarizes well: https://eblog.fly.dev/ginbad.html

Mizu is deliberately boring by design:

  - Built directly on Go 1.22 http.ServeMux
  - Explicit middleware chains with clear scoping
  - No reflection, no codegen, no global state
  - A real request context type that still interoperates with net/http
  - First class graceful shutdown and error handling

i made a clone of beads in rust that uses CRDTs for real time sync to coordinate a bunch of coding agents at the same time! if running locally, it's instant, for git it takes around .6s after your last action. lives entirely in git, and is like... an actual distributed database/issue system, just works, and u never gotta think about it.

Local-first RSS reader/generator with LLM support: Matcha. [0]

https://github.com/piqoni/matcha

I've been working on a LLM fiction writing workflow and associated tools. It's built on agentic coding tools with lots of structure, guidance, prompting, and critique. Almost all of the flow is on the filesystem and using a custom command-line tool, making it accessible to agentic programming tools. (No MCP though; it seems superfluous?)

I was fairly neutral about the tool for a while, but lately I've been going all-in on Claude Code, using things like rules and subagents.

It's also built to "rerender" the story, for instance rewriting it (slightly) for voice, translate it, or target different reading levels or background. I'm interested in translating stories for language learners in addition to simply translating into other native languages.

I'm also hoping to create some stories that stretch the medium. Perhaps CYOA (though I'm struggling with understanding what a CYOA is good at), though also other multi-perspective stories with reader autonomy in how to read through the story. LLMs make it easier to overproduce content, so you can give the reader flexibility without feeling regret that much of the content will be skipped, or rewrite passages for readers who jump into stories part way through.

Producing quality content is hard, and frankly kind of expensive, which is why I'm focused on finished products instead of interactive experiences. Though I do look forward to some future opportunity to take these rich characters that are grounded in full stories and find other things to do with them.

This is the first vibe coding platform to create personal apps that run entirely on chat starting in WhatsApp. We already have some beta customers building and it is really exciting to see what they are using it for:

-wine inventory tracker (lets you rate the wines that you drink and own) -outfit planner (has an inventory of all your clothes) -expenses tracker for trips w friends -personal training coach (keeps track of all the muscle groups that you have used with the purpose of eliminating muscle compensations)

We are quickly releasing beta access for people in the waitlist! Would love to have more people using it.
