The Two Abstractions of System Design: Hide or Reduce

Io_uring Without Readahead
Someone opened a PR to implement readahead in Turso. It was a throwaway implementation, but a good excuse to measure io_uring and understand more about it.

Omarchy: Any User Process Can Escalate to Root
A security issue in Omarchy’s default Docker configuration meant that essentially every program running in the user’s desktop session could escalate to root without a password, sudo, or a privilege prompt. If you use Omarchy, the most important takeaway is simple: update to 4.0.1. I reported this issue privately…

Actually Queryable Executables
I was pleasantly surprised and happy to see that my article ‘Your executable is a SQLite database’ resonated with people. It is a format I have been thinking about for a while, and the idea seems to have struck a chord with others.

Run OpenBSD on DigitalOcean for $4/month
My homepage now runs on OpenBSD with httpd(8) and Let's Encrypt via acme-client(1) . I previously hosted it on GitHub Pages and then eventually moved to Cloudflare Pages because both options were free and easy. Free and easy is cool, and I understand that writing software full-time leaves us wanting absolutely nothing…

Executable Is a SQLite Database
I have been probably obsessed with two things in the last few years: Nix as a tool to explore innovative ideas that require the capability to rebuild the world and replacing ELF with SQLite as an executable format. You might have noticed that these two ideas are well suited to each other.

There's no reason for software to be slow anymore
The other day, I saw a viral tweet saying that people talking about how LLMs are causing slow, bloated, code are going to eat crow once they re-write everything in super-optimized assembly. We're not quite at the point where we want to write everything in assembly , but some variant of what Nolan Lawson said about…

Zig’s Io.Threaded is neat
std.Io.Threaded is one of the implementations of Zig's new Io interface that enables concurrency. This is a boring just use threads impl. I personally find it neat though --- it does this weird thing that I wanted to do for ages, that to my knowledge no one else is doing properly, and implements it better than I…

Linux 7.3 improves performance when running out of vRAM
Earlier this year, I blogged about work I did to improve VRAM management for games. Now, after many months of floating around in mailing lists, the kernel patches are finally merged upstream and queued for Linux 7.3! Hooray!

The Benchmarkpocalypse
There's been a lot of talk about the vulnpocalypse, to which I don't have much to add because I'm not a security person, but I haven't seen much discussion on the closely related (and to be fair, less serious, issue), the benchmarkpocalypse.

Tracking down a Zsh history data loss bug
For many years, I sometimes discovered that commands I was sure I had run were no longer present in my Z shell history file (~/.zsh_history). In this article, I will show you how I tracked down the bug. Spoiler: ultimately, patching Zsh to make it crash loudly and analyzing the crash’s core dump was the winning…

Does anyone run Postgres without PgBouncer?
Almost every notable managed Postgres provider bundles a connection pooler, giving us a strong hint that connection management is a product problem rather than a user problem.

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…
