I'm leading a non-profit team building a pathogen-agnostic early-warning system. As AI systems become increasingly capable substitutes for expert human biologist expertise, the risk that someone could engineer a pathogen to spread widely before detection is going up. We've made great progress and we're now running the world's largest metagenomic...
Running an air purifier on a battery could be really useful in an emergency that combined a biological or nuclear threat with a power outage. Getting one that can run on 12V DC and attaching it to a LiFePO4 battery is about $188 (plus $164 for the purifier) for something...
Most rooftop solar installs don't provide power when the grid is down. The primary goal is to avoid sending power out to the grid where it could injure people working to restore power, but more recently it's been expanded to avoid energized lines extending out from the panel where they...
When Lily was about two she told me she wanted a song about "no". This was ten years ago, and I don't remember why she wanted this, but I made something up: > This is a song about no. > This is a song about no. > This is a...
My older two kids (12y, 10y) like contra dancing, but but have been increasingly unhappy with the available opportunities: a family dance is "too boring", and BIDA is "not enough kids my age". What they wanted was a regular dance, but just kids. So we had one! Ghiblified for privacy...
I like my far-UVC Aerolamp a lot, but haven't been using it much: each time I wanted to get it out I needed to put it up on a tall stand, and ensure it wasn't going to get knocked over. This evening I attached it to the wall, which is...
Julia and I had been giving half since 2014, but in 2025 we drew on our savings to donate 81%. It looks to us like we're in a critical window for keeping the introduction of very powerful AI systems from being disastrous, and we want to do what we can...
