1. Translating 1000s of NeoLatin, Chinese and Sanskrit books for the first time At the Embassy of the Free Mind in Amsterdam, we’ve created https://SourceLibrary.org , a collection of over 15,000 translations of Renaissance and premodern books in NeoLatin, Chinese, Sanskrit, etc. There are a lot of beautiful books to look at — and you can use it with Claude code. API keys available: https://SourceLibrary.org/develope…

neb pointed me to SourceLibrary last month! Congrats on this work, it is very cool and very important -- a great example of AI helping humans.

It is a vast and beautiful collection that I spent hours checking out all sorts of documents, especially the Occult and Alchemy.

https://pastmaps.com This is my side project turned solo bootstrapped startup that I've been working on over the past 2.5 years. Pastmaps has been solely a US-focused platform since it's initial launch but I'm currently working on launching to the UK and Ireland within the next week. If all goes as planned then I should have a first wave of 30K fully digitized, hi-res, and fully georeferenced 1800s ordnance maps avai…

I have found and used this organically and it is a cool mapping tool!

I used it to get better perspectives on the history and place names in Connecticut, from the Dutch and Siwanoy to modern times.

Pendragon, Personal Finance Decision Support system. We built it from the ground up with confidence, provenance, and demonstrated end to end workflows.

Pendragon sits on top of Roundtable, our proprietary Agentic AI framework which splits data into knowledge domains. The key advantage of this is isolated input domains which prevent context bloat and strictly control access and ensure information isolation.

I built an online version (single player and multi player) of a card game that my wife and I created the physical version of a few years ago:

https://play.xor0game.com

The game is basically the XOR operator combined with set-style game mechanics. What makes it better than other set style games, imho, is that there's a mathematical property of "projective sets" that guarantees that there is always at least one valid set on the table.

laboratory.love — independent lab testing of everyday food products for plastic chemicals (phthalates + bisphenols), with all results published publicly. I got nerd-sniped by PlasticList and wanted this kind of testing to keep happening.

It works as a direct service (pay money -> get published results in a couple weeks) and a crowdfunding model (nominate a product and chip in toward its testing goal). If a crowdfunded product doesn't hit its target within a year, contributions are automatically refunded.

Once funded, we buy three samples anonymously through normal retail across different production lots, and an ISO 17025-accredited lab runs GC-MS with isotope dilution. These chemicals are known or suspected endocrine disruptors, companies aren't required to disclose them, and the science is moving fast — the EU cut its "safe" BPA limit by 20,000x in 2023.

I'm also looking at a consumption-weighted model that suggests testing just ~100 high-volume grocery SKUs would cover roughly 40% of the packaged food Americans eat, by mass. That's an absurd amount of public-health leverage for a few hundred thousand dollars, and I'm working out how to fund it as a proper campaign.
