The last time my family was replaced by technology
My great-great-grandfather thought he’d be replaced by technology too. He was a farrier in Mandres-en-Barrois, the small village in rural France where I grew up.

OpenClaw is changing my life
I want to share some thoughts on my recent experience with OpenClaw. Over the past year, I’ve been actively using Claude Code for development. Many people believed AI could already assist with programming—seemingly replacing programmers—but I never felt it brought any revolutionary change to the way I work. Sure…

Solar panels reduced my electric bill in 2022
In late 2021, I had solar panels installed onto the roof of my house. After some bureaucratic delays, the solar panels began producing electricity for me at the beginning of January 2022.

I don’t want to sign up for your newsletter (2018)
When a user moves their mouse from the middle of the page toward the navigation bar — presumably to abandon the page — there are technologies which can track this behavior and trigger a “mouse-out” alert. While this UX element (from companies such as Crazy Egg and Rooster) has great potential, I’ve found it far too…

Can you use a magnifying glass and moonlight to light a fire? (2016)
A magnifying glass concentrates light on a small spot. As many mischevious kids can tell you, a magnifying glass as small as a square inch in size can collect enough light to start a fire. A little Googling will tell you that the Sun is 400,000 times brighter than the Moon, so all we need is a 400,000-square-inch…

Windows 8 — Disappointing Usability for Both Novice and Power Users
Hidden features, reduced discoverability, cognitive overhead from dual environments, and reduced power from a single-window UI and low information density. Too bad.

This is a guide for people who would like less intrusive AI in their tech environment. Maybe you lik

Making Postgres 300x faster for analytics: batching, operator fusion, and SIMD
Last week we released version 0.2 of pgrust. This release was all about performance. It’s 10x faster than the previous version of pgrust. On OLTP benchmarks, pgrust is 30% faster than Postgres, and on Clickbench, Clickhouse’s benchmark for analytical databases, pgrust is 300x faster than Postgres. It’s even ahead of…

Golden Rules of Interface Design (2013)
I have often been asked to distill the vast corpus of user interface design into a few key principles. While I was reluctant to do this, it turned out to be a good exercise to write “Golden Rules,” that are applicable in most interactive systems. These principles, derived from experience and refined over three…

Linux Pipes Are Slow
Errata: Some significant mistakes were pointed out to me by email by Brendan MacDonell. I have included errata, but the results might not be reliable, so take this with pinch of salt! vmsplice is too fast Some programs use a particular system call “vmsplice” to move data faster through a pipe. Francesco already did a…
