Foundry (YC F24) Is Hiring – Come Build a World Model for the Web
### Stop building GPT wrappers. Build a world model instead. — *Why Foundry exists:* Every SaaS app, enterprise tool, and internal workflow without an API will soon be automated by browser agents—not traditional API integrations.

Huge reproducibility project fails to validate biomedical studies
A replication drive focused on results that lean on three methods commonly used in biomedical research in Brazil. Credit: Mauro Pimentel/AFP/Getty In an unprecedented effort, a coalition of more than 50 research teams has surveyed a swathe of Brazilian biomedical studies to double-check their findings — with dismaying results. The teams were able to replicate […]
Differential Coverage for Debugging
I have been debugging some code I did not write and was reminded of this technique. I’m sure it’s a very old debugging technique (like bisection), but it should be more widely known. Suppose you have one test case that’s failing. You can get a sense of what code might be involved by comparing the […]

Writing “/etc/hosts” breaks the Substack editor
An exploration of web security mechanisms and their unexpected consequences The Mysterious Network Error I was working on a technical post about DNS resolution when I encountered something unexpected. Every time I typed the path to the hosts file (/etc/h*sts – intentionally obfuscated to avoid triggering the very issue I’m discussing), my Substack editor would […]
Eurorack Knob Idea
24 Apr 2025Progress: Complete Last year I designed a eurorack module, as a collaboration with Dave Cranmer. When I say designed it, I mean we got about 90% of the way there, then got distracted. With any luck, that module will get finished and released sometime soon. But it had me thinking about Eurorack and […]
