Mojo is now open source, via Simon Willison. I was also struck by the same quote as Simon in the Mojo road map: As Mojo matures through phase 3, we believe it will become increasingly compatible with…

AI has its places, but asking a human to review code you did not write takes the biscuit

To combine archives safely, I had to start by understanding the `tar` and `gzip` file formats. I learnt about tape drives, patent laws, and end-of-file markers.

Ooloi's interface now speaks twenty languages (with two national variations), with varying degrees of confidence. I've added a Translator's Guide for the native-speaking musicians who can tell it…

TL;DR: I believe Odin;s inline assembly is currently the best out of any language.The most important aspects are of this article listed below. I am not aware of any other assembly…

The RC for Umbraco AI Copilot Workspace just went out on our open release branches, so it’s time to properly introduce it. If you’ve used Umbraco...

A JEP-by-JEP tour of JDK 27, tested on the early-access build: compact object headers by default, G1 everywhere, JFR secret redaction and post-quantum TLS.

Three fixes made one React test file 43% faster without changing the tests.

A CSS-only hover-reveal pattern for Gate Seal specs, with keyboard focus fallback, that keeps core numbers visible and tucks extra context behind intent.

It’s a lot; quite a heck of a lot

We dig into the details of the model:

14 years ago, I built my very first native app for iOS together with two friend. Today, Wally 7.0 is out, with a brand new data store, and lots of new features.

I’m creating my own reusable skills. This week I learned something more about the ergonomics: it can be worth it to design what is loaded into context not just around limiting the size, but…

Opus 5 is a strong coding model, but it answers every question with a word salad. My fix used to be a custom output style built on ASD-STE100, the simplified English of aircraft maintenance manuals.…

Tony Mattke continues publishing excellent “Git for Networking Engineers” content. In his latest article, he described how to find who made what changes (and why) in a Git repository . Absolutely…

Note: this post is part of a series. Part one covered packaging a skill in a plugin for Claude Code . Same idea, different tool, this time focussing on GitHub Copilot. After writing that first post I…

So, who knew a trip to the hardware store would lead me to a theory about how to calculate a team's velocity, not in story points, but in complexity points?

Most embedded graphics libraries can’t directly render TTF fonts, instead, they convert bitmap fonts (usually bdf fonts) to a binary format. Since there is no consensus on what this format is,…

Beets is a python CLI tool for fixing up metadata in music collections. I wrote up a guide from my own use on my ~17k track collection because writing instructions is a good way to learn. But also:…

Sometimes I need a simple way to convert an MP3 file into a video suitable for YouTube. Instead of using a static image. I created a small Bash script that generates an animated frequency spectrum…

Much has changed in the ten years since I published Density Estimation with Dirichlet Process Mixtures using PyMC3. To name a few new developments: PyMC is now on version 6, it was on version 3.…

A plug-and-play framework for Bayesian optimization

TL;DR: Don't reuse an existing getter to bolt on new business logic from outside the object. Problems 😔 Duplicated business rules Broken encapsulation Scattered comparison logic Hidden domain kn

Earlier, we went over how we could create scripts in the package.json file of our Playwright framework to add typechecking, linting , and formatting your code with prettier . Want to see the entire…

Unsurprisingly, PyTorch's own built-in GELU function is faster than the hand-rolled one I've been using to date. But I was surprised at how much faster using it made things when training my models. I…

Uber infamously runs thousands of microservices. They ended up with so many services because hundreds of engineers wanted to deploy on their own schedule, with clear ownership of their code, instead…

The core of nixpkgs-multiverse, when you strip away the Nix API and the CLI, is an index. It is a map from (attribute, version) to the revision that shipped it as a JSON file.1 There are actually a…

The Pine Time is a $27 smart watch that runs open source firmware. I’ve had one sitting in the back of a drawer for a year or two. When I saw @steveruizok ’s Tweet about hacking on ESP32 devices with…

Since I use a lot of unique fonts on my site (I love bitmap fonts!) and I have not put much effort into optimizing the page loads, I was noticing quite a bit of Flash of Unstyled Text. Before the…

Google Slides with all the math facts to practice. The post Math Facts Practice – Slides appeared first on Teacher Tech with Alice Keeler.

Introduction The purpose of this blog post is to introduce pg_shmemviz, a new tool to visualize PostgreSQL shared memory. It follows the same approach as pg_walviz, bringing physical layout and byte…

How I build my site with Astro, GitHub Pages, and a few other things.

A port is not simply “the same game in another engine” or “just an emulator”. It is a long series of decisions about what to do with the original content (art, code and audio) to create a new version…

Using an LLM agent to bring productivity metrics into engineering retrospectives

This post was previously published through my newsletter on May 25, 2026. From time to time, I will republish newsletter issues on my blog here if I think people (and search engines) might benefit…

Can a blog post be handwritten? Suppose I handwrite a post on my supernote, then export it as a webp, which supports XMP metadata. Pretty sure I should be able to read that with javascript. Then, I…

Local-only Voice Dictation

Introduction 1 Hardware background (why this is hard) 1.1 What a CPU actually does with instructions 1.2 x86 instruction encoding: JMP and NOP 1.3 Why you cannot just memcpy over live code on SMP 1.4…

Our field has a weird relationship with terminal and command line interfaces. The time has come to re-evaluate it. I’m on a kick lately getting my friends to try building native user interfaces. I…

I wanted a fast, low-memory pure JavaScript image processing library for Lambdas and memory-constrained browsers. Then I expanded into codec compatibility and started tackling science, geo, and…

Doing my best not to press the push-to-win button.

I don’t think we are ready to NOT read the output I read the code for things that are important. Personal projects, non-critical, funsies - sure I’ll allow it through and take the output…

Three months ago we had 34 microservices and 34 Grafana dashboards, each one hand-built by whoever owned that service at the time. Some had rate/error/duration panels. Some had CPU and memory but no…

This post is about Windows. Last time we saw that sockets are pretty much just handles, and as such, they can be inherited. If a process creates an inheritable socket and runs CreateProcess with the…

Why I’m porting Phoenix LiveView to Go, the rules I’m setting to avoid stalling like the attempts before mine, and the first four milestones.

The Node.js histogram API gets Welch's t-test, Mann-Whitney U, EWMA for streaming stats, SLO burn rate tracking, and a CBOR-based export/import format.

Introduction For 14+ years, every shader that bgfx compiled, starting from the initial commit, went through a preprocessor written for the Amiga with origins in 1984: fcpp - Frexx CPP (C…

As AI makes database operations easier, the enduring role of database tools may shift from UI to governance.

RollTab is a real-time piano MIDI autocomplete model and iPhone app.
