Memories of .us
How much do you remember from elementary school? I remember vinyl tile floors, the playground, the teacher sentencing me to standing in the hallway. I had a teacher who was a chess fanatic; he painted a huge chess board in the paved schoolyard and got someone to fabricate big wooden chess pieces. It was enough of an…

Running a business means contact with reality
A year ago I decided to help build a service business for my mom because I wanted to learn about marketing and business. One of the largest blindspots engineers have is around sales and marketing. I was determined to not fall into this trap, but marketing seemed like a skill I couldn’t just learn by […]

I don't care how well your "AI" works
The other day I was sitting on the doorstep of a hackerspace, eating a falafel sandwich while listening to the conversation inside. The topic shifted to the use of “AI” for everyday tasks, people casually started elaborating on how they use “chat assistants” to let them write pieces of code or annoying emails. The…

Google steers Americans looking for health care into "junk insurance"
Being "the enshittification guy" means that people expect you to weigh in on every service or platform that has been deliberately worsened to turn a buck. It's an impossible task (and a boring one besides). There's too much of this shit, and it's all so mid – a real "banality of enshittification" situation.

A Look at Rust from 2012
Recently I was scrolling through brson’s Rust quote database and stumbled upon a link to the official Rust tutorial from the very beginning of 2013. It says Rust 0.6 in the corner, but it lists many things that were removed in 0.6, so it’s likely closer to 0.5. I heard tales of old Rust before, but not of how the…

New layouts with CSS Subgrid
Subgrid allows us to extend a grid template down through the DOM tree, so that deeply-nested elements can participate in the same grid layout. At first glance, I thought this would be a helpful convenience, but it turns out that it’s so much more. Subgrid unlocks exciting new layout possibilities, stuff we couldn’t do…
