Been nerd sniped recently so am working on a Rust version of markdownlint-cli2. I'm tired of having a node dependency in my projects and this seems like a constrained enough problem space that I'll actually get around to doing it.

#12Working on https://ziva.sh/, an AI agent for game development. It uses MCP to integrate with Godot, a leading open source game engine.
It's coming together really nicely, targeting a beta release later this month. If anyone is interested in game development and wants to be a beta tester, lmk :)

#13I am working on methods to automate my VC firm. We have a small team and many different tasks to do. I’ve had success with using LLMs to help us automate various projects. But I appreciate any open source tools, techniques, readings, etc. if anyone knows any!

#14A modern QuickBooks, based on beancount, WorkBill (https://workbill.co). You can play with it at https://demo.workbill.co.
Unlike traditional accounting platforms we expose the ledger model directly which enables our customers to model complex transactions even when we do not have direct support for it.
Been working on this for a month, and it uses Elixir, Phoenix and InertiaJS with React.

#16I'm working on rebuilding Playwright from the ground up, but focused on automation and self healing using LLMs.
It's called Stagehand (https://github.com/browserbase/stagehand) and we just released v3, which is a total rewrite.

#17Manabi Reader: Japanese learning through reading
I recently added FSRS (besides also having Anki integration). Now I'm working on replacing the need for reviewing flashcards by having reading activity automatically mark flashcards (current and future) as reviewed, so that you can get many of your reviews in just by reading native materials that interest you instead of sacrificing most of your study time to contextless flashcard grind.
I'm also working on a manga mode using a new manga OCR tech I have licensed out of academia that is ahead of state of the art alternatives.
This project now sustains my full-time focus.

#18Building https://www.hessra.net/, an authorization system based on the Biscuit token format (decentralized, signed, and attenuable). The goal is to push beyond JWTs and Zanzibar-style policy engines by giving every machine-to-machine request its own embedded, verifiable authorization logic in a small capability token. These tokens can be delegated, restricted, and verified locally with no extra network calls required after getting the token.
Early use case is replacing API keys with identity tokens that expire, delegate, and prove possession and then can be used for easy step up to fine-grained authorization. There's some pretty interesting authorization stuff you can do, like having multiple parties sign off before a token is valid or requiring a series of micro-services sign a token for it to be valid.

#19A kernel extension-less sshfs for macOS. I tried using FSKit and got halfway before I felt too constrained by the extension security model (must be app sandboxed, must be approved by the user in system settings). Now it’s just a standalone command line binary that doesn’t require any special permissions since it proxies NFS to SFTP. Everything “just works” and performance is reasonable

#20I’m working on Reflect [0], it’s a privacy-focused app for self-tracking and self-discovery. You can track metrics, run self-experiments, set goals, view correlations, visualize your data, etc.
