An IDE for solid modelling with distance fields
Lately I keep feeling that the internet has become a worse place. Not necessarily louder or slower, but emptier in the places where people used to be visible. Ten or fifteen years ago I could move through small personal blogs, read along in forums, disagree in…
Pirating the Pirates
Notes from the underground of film preservation.
The operating system Microsoft definitely did not make. An interactive parody of Windows 11, Microsoft 365, Copilot, updates, ads, and subscriptions.
I Have a Fetish for Rounded Corners
I've had a love affair with rounded corners for too many years. Recently, I came across my first business card, which I had printed in 2011. It had, guess what, rounded corners. I remember hunting for a printing shop that could make them that way. Failing to …

Compute allocations are the new slots of time and freedom. Does getting more of them depend on what the machines want?
Cutting LLM tokens on big spreadsheets — Andrei Kushniarou
What each step really saved, measured on a 50,000-row report, while I was building an MCP server for Google Sheets.
Editor is an extremely simple-to-use terminal text editor. It was written in C, and it offers simplicity while being very responsive and performant. Editor was …
Test-driving Jev, a decision model trained for calibrated probabilities, on identity resolution across five data sets. Compared against gpt-oss-20b, Claude Haiku 4.5, Sonnet 5 and Opus 5.5, and traditional entity resolution (Fellegi-Sunter and gradient-boosted…
I work on AI evals and reliability for agentic systems. Skeptical of tooling hype, mostly because I keep measuring it.
Predictable Swarm Scaling
Under suitable conditions, we can use simulation to roughly estimate the best structure for an agent swarm and its scaling law.
Your CI database picks different plans than production because its statistics differ. Inject production stats with PostgreSQL 18, or generate rows that carry the distribution. Here is how to tell which one you need.

Edge Is Pretending to Be Chrome
I don't think there was any official announcement, but I'm pretty sure Microsoft is secretly trying to trick you into using Edge. Well, it has always been trying to trick us, but this time it's even m
