Notes from building a blog in Django
We launched the Datasette Cloud blog today. The Datasette Cloud site itself is a Django app - it uses Django and PostgreSQL to manage accounts, teams and soon billing and payments, then launches dedicated containers running Datasette for each customer.

QtWayland 6.6 Brings Robustness Through Compositor Handoffs
Every release has a killer feature. Qt 6.6 features the opposite - staying alive. This blog post describes work to make Qt clients more robust and seemlessly migrate between compositors, providing resistance against compositor crashes and more.

I think I kind of hate lazy loading
Yesterday I was on a train. I clicked on a link and my browser loaded a long article for me to read. Halfway through reading it, the train went into a tunnel and I lost signal. That meant I couldn't see the images on the other half of the page for the rest of the journey. I had a sea of broken images. Even though the…

JEP 454: Foreign Function and Memory API
Introduce an API by which Java programs can interoperate with code and data outside of the Java runtime. By efficiently invoking foreign functions (i.e., code outside the JVM), and by safely accessing foreign memory (i.e., memory not managed by the JVM), the API enables Java programs to call native libraries and…

You Don't Need UUID
I've experienced first-hand how using UUID hurts the usability of computer systems, and I want you to understand why you certainly don't need it.

Develop with Cocoa for Apple devices without using Objective-C
Summary In this post I’ll go into detail about how, during my contracting work for Shimmer Industries (a company founded by Eskil Steenberg which is focused on developing a real-time lighting designing software), I worked on a piece of software which enabled us to use the MacOS and iOS APIs using a custom C API…

Intuitively Understanding Harris Corner Detector
If you ever tried to learn how the Harris corner detection algorithm works, you might have noticed that the process is not intuitive at all. First, you start with an energy function, approximate it using Taylor approximation, get a matrix from that, then find the eigenvalues of that matrix, etc. But when you come to…

A systematic approach to debugging
I've got a reputation at work as being a skilled debugger. It's a frequent occurrence that the weird stuff lands on my desk [1] after it goes through another skilled engineer or two. To say my job is substantially "debug the weird shit" would not be an understatement and I'm here for it.

Removing garbage collection from the Rust language (2013)
I've been floating ways to simplify the memory management story in Rust around the core team lately. Memory management is a contentious topic, since we've worked hard to get to the current state of things, and with the push toward stability lately, there is a (quite reasonable!) resistance to any changes at this…

What I have changed my mind about in software development
I really like this quote from Jeff Bezos: “Anybody who doesn’t change their mind a lot is dramatically underestimating the complexity of the world we live in.” Lately I have been thinking about wha…

Training and aligning LLMs with RLHF and RLHF alternatives
I frequently reference a process called Reinforcement Learning with Human Feedback (RLHF) when discussing LLMs, whether in the research news or tutorials.

Flake8-Logging
The Python standard library’s logging module is a go-to for adding observability to applications. Many tools also integrated with it or enhance its capabilities, such as structlog and Sentry.

I wrote a string type
I write compilers for fun. I can’t help it. Consequently, I also write a lot of parsers. In systems programming, it’s usually a good idea to try to share memory rather than reuse it, so as such my AST types tend to look like this.

Why you might want async in your project
There is a common sentiment I’ve seen over and over in the Rust community that I think is ignorant at best and harmful at worst.

Learning Zig
Welcome to Learning Zig, an introduction to the Zig programming language. This guide aims to make you comfortable with Zig. It assumes prior programming experience, though not in any particular language.

My mental model of Clojure transducers
I’ve been programming in Clojure for a long time, but I haven’t been using transducers much. I learned to mechanically transform (into [] (map f coll)) to (into [] (map f) coll) for a slight performance gain, but not much beyond that. Recently, however, I’ve found myself refactoring transducers-based code at work…

Bare-Metal Kubernetes, Part I: Talos on Hetzner
I’ve been running a Kubernetes cluster on a mix of virtual and bare metal machines with Hetzner for about a year now, and while the setup has served me well, being a very exploratory exercise at the time it wasn’t very well documented.

Using LD_PRELOAD to cheat, inject features and investigate programs
