Jepsen: Crate 0.54.9 version divergence
In the last Jepsen analysis, we saw that RethinkDB 2.2.3 could encounter spectacular failure modes due to cluster reconfiguration during a partition. In this analysis, we’ll talk about Crate, and find out just how many versions a row’s version identifies.

Interactive Programming in C
I’m a huge fan of interactive programming (see: JavaScript , Java , Lisp , Clojure ). That is, modifying and extending a program while it’s running.

Prompt – A terminal for a container-oriented desktop
Prompt is a terminal that marries the best of GNOME Builder’s seamless container support, the beauty of GNOME Text Editor, and the robustness of VTE. I like to think of it as a companion terminal to Builder. Though it's also useful for immutable/container-oriented desktops like Fedora Silverblue or Project Bluefin…

The input stack on Linux: An end-to-end architecture overview
Let's explore and deobfuscate the input stack on Linux. Our aim is to understand its components and what each does. Input handling can be divided into two parts, separated by a common layer. We’ll try to make sense of all this, one thing at a time, with a logical and coherent approach.

Wayland is pretty good
I started working on Flyaway with the intention of becoming familiar with Wayland, its protocols and extensions, and the wlroots library. Instead, I ended up genuinely liking all three.

Migrating a 40TB SQL Server Database
Initially, I wasn’t sure whether to write about this migration project, but when I randomly asked if people would be interested, the response was overwhelming. This was a long, kind of boring, very repetitive, and at times incredibly frustrating project, but I learned a lot, and maybe someone else will learn from this…

An ARM Homelab Server, or a Minisforum MS-R1 Review
I’ve always wanted an ARM server in my homelab. But earlier, I either had to use an underpowered ARM system, or use Asahi which not only requires expensive Mac hardware but also slowed down in the past few years.

Systemd: Enable indefinite service restarts
When a service fails to start up enough times in a row, systemd gives up on it. On servers, this isn’t what I want — in general it’s helpful for automated recovery if daemons are restarted indefinitely. As long as you don’t have circular dependencies between services, all your services will eventually come up after…
