Three new features that allow the exploration of more Fediverse instances.

I describe how we use testcontainers to remove manual setup.

There exist an IntelliJ plugin to get the permalink for a line or a range of lines directly from the IDE.

I will start writing shorter blog posts, focussing on topics that come up in my day-to-day work.

I’m taking a look at systemd timers, which provide a convenient way to execute recurring tasks.

I take a first look at how Threads implements ActivityPub.

I explore how Mastodon replies are handled in ActivityPub and why this leads to replies not showing up on all instances. I also take a look at the boost and like counters to find out what the numbers really mean.

Using ActivityPub.Academy, I’m exploring how Lemmy uses ActivityPub. The post uses real-world examples that you can try on your own.

I explain how I’m using ActivityPub.Academy to explore ActivityPub.

Introducing ActivityPub.Academy, a learning resource for ActivityPub. It is a fully functioning Mastodon instance that shows activities sent between instances and allows to explore ActivityPub data.

I’m explaining how to use the install section of a unit to add requirement dependencies and how this works behind the scenes.

I’m taking a closer look at four basic directives to define systemd services.

Introducing systemd-by-example.com, a playground for systemd that allows to do experiments with systemd right from your browser!

Based on the minimal system developed in Part 1, I’ll take a closer look at systemd dependencies.

The first article in a series where I explore aspects of systemd by creating small examples with the help of containers.

I present some techniques to make a custom shell prompt feel snappy and responsive.

I take a closer look at shell builtins and environment variables, and explain at the example of CDPATH why not every variable should be exported.

I show how I improved four of my shell workflows to parameter-less commands with the help of fzf.

I show how to turn experiments with the GitHub CLI into a script to monitor a GitHub CI pipeline.
