Twelve years of distributed SQLite
In September 2014 I published a short post announcing rqlite. The idea was simple: take SQLite, put a Raft log in front of it, and replicate every write to a cluster so that the loss of a node did not mean the loss of the data. The source went on GitHub that same weekend. As…

The other Sean Byrne doesn't exist
A fictitious Sean Byrne ended up on a U.S. government restricted-party list. Sixteen years later, Apple, Nasdaq and others have mistaken me for him.

Google Workspace thinks my domain is an email provider (2025)
I was creating a Google Workspace account for my company, as everyone knows, it’s a pretty straightforward sign-up process, until I’m hit with a weird, confusing error when I type my domain name:

Someone at BrowserStack is leaking users' email addresses
Like all good nerds, I generate a unique email address for every service I sign up to. This has several advantages - it allows me to see if a message is legitimately from a service, if a service is hacked the hackers can't go credential stuffing, and I instantly know who leaked my address. A few weeks ago I signed up…

When everyone has AI and the company still learns nothing
Are people using AI, or is the organization learning from it? What changed because we spent those tokens? And who moves discoveries from individuals to teams to organizational capabilities?

Why I Left Google DeepMind
I fought against Google’s Pentagon AI deal from the inside. Powerful people and institutions failed to keep their AI ethics promises under pressure.

The time I didn't meet Jeffrey Epstein
Last night, I was taken aback to discover that my name appears in the Epstein Files, in 26 different documents. This is despite the fact that I met Jeffrey Epstein a grand total of zero times, and …

LLVM: The bad parts
A few years ago, I wrote a blog post on design issues in LLVM IR . Since then, one of these issues has been fixed fully (opaque pointers migration), one has been mostly fixed (constant expression removal), and one is well on the way towards being fixed (ptradd migration).

AI Has No Wisdom and Neither Will You
Certainly the industry is transforming, however, the people and organizations falling into the trap of no longer reading and writing code only do so at their peril.

The solution might be cancelling my AI subscription
Except for the SaaS, almost none of this is useful and I don't want to maintain any of it. I accidentally run a news outlet which is surely a liability. Sure, it has helped me "learn AI tooling" and I use many of these tools, but I didn't need them. I can't afford to maintain any of them, not in terms of time…

The problem is not AI code, but not knowing about system architecture or intent
If we think writing code is dead, and AI is generating all codebases, I still think the bigger problem is people or full teams not knowing anything anymore about the system...

A4 Paper Stories
I sometimes resort to a rather common measuring technique that is neither fast, nor accurate, nor recommended by any standards body and yet it hasn't failed me whenever I have had to use it. I will describe it here, though calling it a technique might be overselling it. Please do not use it for installing kitchen…

I am happier writing code by hand
I felt the familiar feeling of depression and lethargy creep in while my eyes darted from watching claude-code work and my phone. “What’s the point of it all?” I thought, LLMs can generate decent-ish and correct-ish looking code while I have more time to do what? doomscroll? This was the third time I gave claude-code…

I love software rendering
Sharp pixels, gritty colour banding, and DOS games running at resolutions their own era couldn’t manage. Why I still prefer the software renderer, and why it needs a fast PC.

Claude Code: connect to a local model when your quota runs out
If you’re on one of the cheaper Anthropic plans like me, it’s a pretty common scenario when you’re deep into Claude coding an idea, to hit a daily or weekly quota limit. If you want to keep going, you can connect to a local open source model instead of Anthropic. To monitor your current quota, type: /usage
