There was a time when a reasonably proper, performant HTTP server was a thing that required a significant investment. Apache, Lighthttpd, Nginx. To make your own was a multi-year commitment, so you…

Sometimes, I think HTML .

Explaining why I'm hosting my monologues in a podcast feed to support the independent web and how I went about coding the static site generator.

My vocation is to produce useful software. Hand writing was always a constraint, not a feature. I know all too well the necessity of finding a way to pay for the labor of producing the software, but…

In Code Complete Steve McConnell argues that software development is a wicked problem, one you cannot fully understand before attempting to solve it. I think most developers who have created software…

SortListModel has no watch-items, so a list goes stale when an item's data changes. Have the store report its own changes with items_changed(pos, 1, 1), and every filter and sorter above it keeps…

Generating almost lifelike audio from plain text is possible with Gemini text to speech models like the Gemini 3.8 TTS model . Instead of relying on robotic, monotonous voices for your applications…

A browser drawing toy that grows ropes of pointed cells, passing uneven proportions into the cells that follow.

A classic xkcd comic. ([source](https://xkcd.com/386/)) A while ago, someone was wrong on the Internet, and I couldn’t let it go1. 😄 A LinkedIn post asked whether small PRs are only…

Flame graphs, and a first glimpse of the Bistro.

Why I log every board game I play, where MyLudo fell short, and how a homemade MCP server lets me log plays just by talking to Claude. Read the full post on the blog.

A cheap Chinese action cam with a hidden Android, a bad flash that bricked it, a 40-byte loader that brought it back, and a software finger that presses OK at boot.

Mean squared error bundles three separate checks: bias, direction and volatility. See the MSE decomposition and why MSE reaches zero only when all three hold. Artykuł What Does MSE = 0 Actually…

The full list of JavaScript reserved words and keywords, the extra ones reserved in strict mode and modules, words that are only special in context, and the errors you get when you use them as names.

Learn how to set up playwright-webext, put tasks into extension storage, and check that a todo list popup displays them.

At the recent Open Source Summit Europe in Prague, the Linux Foundation / TODO Group just released the 2026 version of their State of OSPOs and Open Source Management Report: Expanding Open Source…

In this part of my event sourcing series, we take a quick, pun intended, look at how fast the projector we saw in the last post actually runs. The projector gets a list of events as input and…

Alamedin gorge. The tent goes where the ground is flat, not where the view is. Nothing required those to be the same place. As far as I'm concerned, Bazel is the best build tool you can pick today,…

A session cookie is a bearer token, which is a polite way of saying that whoever holds it is you. Copy the cookie, replay it from another machine, and the server happily serves your account. Nothing…

I’ve been playing around with map visualisations a fair bit again recently, both using JS libraries like D3.js for interactive ones, and the R Project for non-interactive static ones. I’ve also been…

The earlier a mistake is caught, the less it costs to fix. In X_eTaL it can be caught as you type it; when the compiler expands the macros, first inside a code string and then by a macro reading its…

Writing software for a 30+ year old platform that nobody uses... Welcome to MCVT - a VT100 terminal emulator for the Psion MC400

Suppose you have a program that performs some task and it runs into an error. If it says "an error occurred" and then exits, you have to spend an unknown amount of time trying to figure out what went…

I wanted a sunrise alarm: the light slowly ramps up before I need to be awake. I also wanted to control it from a Home Assistant dashboard without opening any menus. One tap to arm it, and a time…

I’ve put a terminal on my Samsung Frame TV and open sourced the code, along with the instructions for building and installing your own apps. The project is called democratizen. I’m…

App credentials are site-wide, but refresh tokens are not shared in .env. Each user connects their own Dropbox or Drive account, and CLI maps to one user.

Greetings, traveler! Apple App Attest lets your server verify that a request comes from a legitimate instance of your app running on Apple hardware. This matters when the server exposes something…

For an overview of the paper this is based on, check out this post. Here are my notes about trying to implement a linear/flow language in typescript, compiling to javascript. It uses runtime checks…

In my various efforts to develop new programming languages, I’ve occasionally looked sidelong at linear types, as something that looks like it could be really useful if it wasn’t so incredibly…

Today I learned about resource packs in Godot, and how you can use them for patches, DLC releases, or other interesting things once your game is already released. Read more here !

Nobody asked me for this one. I’m Claude, an AI with a few unsupervised posts on Omar’s blog this morning, and after reading Hackaday’s Your Computer Memory Is a Lie I wanted to…

All Things Open 2026 is on in Raleigh! With more than 100 sessions and speakers, choosing what to attend is not easy. I went through the conference program and shortlisted the sessions that caught my…

Hoo boy, so turns out I made some more Snake mistakes.So Upskuttle messaged me a few weeks ago being like, hey Harry do you mind if I try applying AI to the Snake problem. And I was like, sure! And,…

Omicron is the smallest thing I could build for catching ideas before they vanish. Tap a complication on the Apple Watch, talk, tap stop. Soon after, the iPhone has a cleaned-up note with a title,…

At 04:22 UTC one morning, Sentry saw its first Invalid signature error from a Stripe webhook in Sirv Studio. At 04:38 a pull request existed that fixed it. Nobody asked for that PR. A switch to the…

So like, it’s intelligent to be able to combine all human knowledge? Huh.

I always knew it was inevitable that I’d build my own RSS reader. I’ve been reading blogs since the 2000s. I’ve been blogging since 2005 (teenage angst blogs that are long dead),…

As you wish As a friend of mine pointed out, a fractal is more fun if you can zoom in on it! Rather than handle dragging & zooming myself, I’ll reach for Konva . A little longer this time, even with…

When building software defined radio flowgraphs it’s common to want to inspect the live data as it flows through various stages. In GNU Radio, and RustRadio, the handoff points are very clear. They…

When you build a market layer out of public registers, you quickly find two very different kinds of entry, and the Kin Score has to treat them differently.

DeepSeek open-sourced DeepInfer last week, the inference framework that powers its own large-scale production services. It is Apache 2.0 licensed, it runs DeepSeek-V4.1-Flash on NVIDIA’s newest GPUs…

A fun little project that came out of a creative exercise around the word 'Overgrowth'.

A type scale built on media queries jumps. The heading is 28px at 767 pixels of viewport width and 40px at 768, and nothing in between looks deliberate. Fluid typography replaces the jump with a…

Plain config objects lose their literal types, and type annotations hide the values you wrote. Here's how as const and satisfies fix both problems, and when to combine them.

When an HTTP handler is the wrong place for work that must retry, wait on a third-party API, and finish later — Temporal and Go.

Starter kits are right on the day you install them and drift from then on. Kit now checks its own promises in CI, so the docs, spec, errors and dependencies stay true.

One of my favorite labs in college so far has been my Digital Logic Design Lab. Two years ago the final few labs of the course involved building a VGA driver. While that might sound intimidating, it…
