As a follow-up to the similar milestone reached for our WSL image a few months ago, I’m happy to share that Arch Linux now has a bit-for-bit reproducible Docker image! This bit-for-bit reproducible image is distributed under a new “repro” tag. The reason for this is due to one noticeable caveat: to ensure…
three layers of system health, AI as cognitive system 3, what's expensive if agents make coding free, and the future of source code
On my Introduction to A* page I cover the basics of the A* graph search algorithm for finding shortest paths. Here’s an example from the town of Denerim in Dragon Age Origins. Try moving the start and goal to see A* in action:
We're not in a February 2020 moment, and ordinary people will be fine
How to run Claude Code with the `--dangerously-skip-permissions` flag in a safe way

Hundreds of hours, many late nights, and a working Game Boy emulator in F# with sound, running on desktop and web.
A selected list of timeless and influential papers in distributed systems that shaped the research in the field. Intended to serve as a good…
I’m writing this post from a hospital bed. And I couldn’t be happier. You hear folks say chemotherapy sucks, but until you go through it yourself, you don’t really know how bad it can be. It remains a popular activity only because it’s better than the alternative. My first exposure to chemotherapy was with this […]
Tim Cook had an extraordinary run — and impeccable timing, both in terms of when he became CEO, and when he is stepping down.
Where are they now? You won't believe her new look!
Anthropic may have just committed the biggest business blunder of 2026 -- and we're less than two weeks in. To understand why, let's briefly rewind to 2025, the year when agentic AI went mainstream.
How I repurposed my old gaming PC to set up a home server for data storage, backups, and self-hosted apps.

I have a thing for lamps. Especially designer lamps from the past. I occasionally share them on X and Instagram, and people always ask me about the brands and models. I love lamps so much that I designed one myself. So I decided to give a tour of the lamps
The home of Code & Visuals
These lines are very difficult for me to write because I feel like digging my own grave. AI systems are improving by leaps and bounds. From the early 2022 fumbling release of ChatGPT, which couldn’t correctly count the number of a’s in my name (it claimed two), we reached OpenAI’s release of math papers where an…
My wife and I recently went on a 7 week holiday around Europe. Although we each took a massive backpack, we wanted to travel fairly lightly. I took a single universal power brick. This little unit was all I needed to charge my various gadgets. It has a hefty USB-C PD (Power Delivery) port for rapid charging of my…
A blog about software craft and quality
With Anthropic altering rate limits, we can find other places to spend our money. I have chosen Zed editor with OpenRouter for maximum flexibility.
A single intravenous dose of Ewingella americana achieved complete tumor elimination in 100% of treated animals, with no detectable toxicity—outperforming chemotherapy and immunotherapy.
Python loses every public benchmark by 21-875x. I took the exact problems people use to dunk on Python and climbed every rung of the optimization ladder -- from CPython version upgrades to Rust. Real numbers, real code, real effort costs.
Simplified Android Development
Some days I get in bed after a tortuous 4-5 hour session working with Claude or Codex wondering what the heck happened. It's easy to blame the model - there'...
My disdain for astrology is so utter, and my esteem for Godier’s previous work so high, that it simply never occurred to me that he might have actually made and submitted to the App Store an astrology app, let alone that he’d then feign surprise and frustration that an astrology app was rejected for being an astrology…
An interactive visualization to understand how neural networks work
Software is degrading all around us, for obvious reasons. I've written about this before. All else equal, if you increase your code production by 10x but you don't reduce your error rate by a factor of 10, then your production app is buggier than it used to be. I've seen threads where people also have...
