I love vertical tabs. I used Tree Style Tab for years, then switched to Sidebery and recently to Firefox's native vertical tabs . I like them, but I was annoyed how pinned tabs looked. By default…

Both put a Go userland on top of the Linux kernel, but one wants to be a small UNIX you can read in an afternoon and the other wants to be an appliance with nothing you don’t need.

A mate wanted to keep some WeChat voice messages as ordinary audio files and asked me to help. It sounded like a small conversion job: find the files, turn them into MP3s, and give them sensible…

I came across on X that checks whether a shared link reveals the sharer’s social account. I was curious: when I send someone a post, what else goes with it? I started by looking at the request…

I keep forgetting how to release my own software. My major project Clientele has a PUBLISHING.md file with every step written down, but I release so rarely that I end up with the file open in one…

A KOReader plugin that puts Lichess puzzles on my e-reader, so I can do a few before bed without picking up my phone.

Scheduled events have existed in ZenGM for a long time, mostly to support the historical real players mode in BBGM. Beyond that built-in mode, they've mostly been reserved for custom roster file…

Most modal libraries exist to solve four problems: stacking the overlay above everything else, trapping focus, closing on Escape or an outside click, and wiring up the accessibility attributes. HTML…

TL;DR: I built wanderbooks . It's a free, open source, formally verified double-entry accounting engine. The only way to change your books is by talking to an AI (Claude Code or Codex) over MCP. The…

I have just returned from SPLASH 2026, which was colocated with ISSTA in Oakland, California. This was my first academic conference, and I thought it might be worth writing down some initial thoughts…

Now that my port of CamelForth-80 to the Sega SG-1000 is sort of working, it’s time to get it working better. There’s a lot of undone odds and ends and little bugs that I need to take care of before…

It took me a while, I know, but two new versions of CanCanCan are here: 3.7.0 is out already, and 4.0 is coming. Here is what changes and why I have two of them.

A persistent, recoverable execution layer for zot. The whole conversation lives in a durable store instead of in the running process. That one decision makes a crash a pause, and lets you pick up the…

It's October. New month, new agent-shell update. If you missed the last post, have a look at the 0.78 update. While the latest changes are focused primarily on bugfixes and polish, we have a handful…

Scroll-driven animations are one of my favourite things in CSS. But if you have ever tried to build an interactive story with them, you probably noticed that scrubbing is not always what you want.…

Starting code · Completed code I learned top-down recursive-descent parsing from Jack Crenshaw’s Let’s Build a Compiler!. I’ve used it many times since, including for a custom color formatter I wrote…

C# 15 adds with(...) arguments to collection expressions, so you can finally set a comparer or capacity without abandoning the [a, b] syntax.

Four weeks on a laptop with an integrated GPU: the pond gets a surface, fog becomes a medium, the goldens leave git, and night stops being black.

SWAR Zig SIMD IPv4Again?Once again I got hooked on the deceptively simple problem of parsing IPv4. This time it happened while reading 192.168.1.1 is too short for SIMD. The gist: the fastest parser…

An idea arrives while you are in the middle of something else. In Joplin, New to-do creates an empty note and opens it: the note you were reading is gone, and Back lands at its top. A user asked in…

CSS Grid Lanes supports stretch alignment along the stacking axis, allowing items to fill any remaining space left between other items, and avoid a jagged end edge. See Aligning items within their…

Make direnv load every .envrc file in a directory's ancestors, not just the closest one. direnv has a built-in source_up function for this, but it must be added to every .envrc file and I…

My talk from Devoxx Belgium, “Kill All Mutants! (Intro to Mutation Testing)”, has been posted at https://www.youtube.com/watch?v=AsVt_dzTmN4.

Jujutsu has no “create a branch” step. Detached HEAD, anonymous branches, and bookmarks helped me finally understand why Git branches are pointers, and why Jujutsu uses bookmarks instead.

In an earlier article we added semantic search to the Koog-based AI agent in the Confetti Compose Multiplatform sample. That used Gemini both for the LLM driving the agent and for the embeddings…

James Shore posits that each person-month spent writing code results in 10 days of maintenance in the first year, then 5 days every year after that. Naïvely interpreted, this is a threshold-based…

A few people have asked how I’m coding with AI at the moment, so here’s a quick rundown of my setup, with links to everything in case you want to copy it. The short version is that I run…

Normally, we write source code and use a compiler to turn it into machine instructions that a CPU can execute. Reverse engineering starts from the other end: we have the executable, but not…

Many years ago, I made a little jQuery plugin called Easy Sortable Tables. It works exactly as promised: point it at a table and it upgrades the UI so a reader can sort the rows by clicking a column…

Thor is a really nice command-line runner, with much nicer support for arguments than Rake imo. The Rails framework supports both, but since Rails 5.1 most Rails’ built-in commands (like bin/rails…

Most geospatial tools were not built with spatial as a core feature. Spatial got bolted on later, and you can feel it the moment you try to run a real query. I ran the same four spatial queries…
