  • Retrospective: spending 500 billion Codex tokens

    For the last month, I’ve had unlimited access to OpenAI Codex. It’s been such a weird experience! This post is about my experience, learnings, and reflections. What I ended up shipping Quite a lot. I’m sharing this early in the post to put the rest of it in perspective. It took 500 billion tokens in…

  • General, automated WordPress-to-WordPress sync is unsolvable

    Twenty-three years into WordPress, the general problem of site synchronization is still unsolved. We have great tools for the slices, but nothing for the whole. You can’t reliably automate any of these tasks beyond basic sites: This post exhaustively covers what makes these problems so difficult, and what we can do instead. It is a…

  • Running 80 concurrent Codex sessions

    With unlimited tokens, the constraint becomes compute power: CPU, memory, disk space. Dan Luu’s and Dennis Snell’s work inspired me to move from managing Codex sessions to assigning it a big task and a pool of compute resources to maximize. It burns tokens! I’ve got through ~120 billion tokens since Thursday. Dan is at ~300…

  • AI, generate 100 designs for WordPress Playground

    I wanted to revamp WordPress Playground UI for a while but I couldn’t get any useful results from LLMs. Until today. I’ve shared my struggle on Slack and Chris Huber inspired me to ask it not for 100 iterations on one design, but for 100 different designs. So I did. And I got 100 designs.…

  • My notes from „Butterick’s Practical Typography”

    I’ve just refreshed Butterick’s Practical Typography. The first time I read it was a couple of years ago and I’ve surely forgotten a bunch since. Here are a few thoughts I had during this read-through. Typography is like theater Butterick cites three principles from The Elements of Typographic Style: The three principles read exactly like…

  • SQL Isolation levels: Foundational database feature most developers don’t know about

    I looked at SQL queries through the lens of isolation levels ever since my brother showed me that concept about 16 years ago. I’ve noticed many, many senior devs are unaware of this fundamental database feature. Here is a short primer on isolation levels that every backend developer should read.

  • Do less with AI. And breathe.

    Waiting for AI to finish is uncomfortable. I found I feel better and get more done when I stay with that discomfort without acting on it. When, instead of rushing to open my fourth concurrent agent or reply to another Slack ping, I just stay right there, present. Maybe I’ll close my eyes for a moment and focus…
