Together with Modal, I’m happy to announce that the Sovereign Tech Agency is investing nearly €510k into Flatpak development.

This year was the fourth year in a row that a bunch of display driver and compositor developers met for the Display Next Hackfest, to discuss, present, and tackle issues related to displays, GPUs, and compositors.

It’s a question I had to ask myself multiple times over the last few months.

I published three Rust crates: name-to-handle-at: Safe, low-level Rust bindings for Linux name_to_handle_at and open_by_handle_at system calls pidfd-util: Safe Rust wrapper for Linux process file descriptors (pidfd) listen-fds: A Rust library for handling…

The Wayland core protocol has described surface state updates the same way since the beginning: requests modify pending state, commits either apply that state immediately or cache it into the parent for synchronized subsurfaces.

For all the rightful criticisms that C gets, GLib does manage to alleviate at least some of it.

Graphics drivers in Flatpak have been a bit of a pain point.

Together with my then-colleague Kalev Lember, I recently added support for pre-installing Flatpak applications.

Yesterday I released Flatpak 1.17.0.

A while ago I wrote about the limited usefulness of SO_PEERPIDFD. for authenticating sandboxed applications.

Andy Holmes wrote an excellent overview of XDG Intents in his “Best Intentions” blog post, covering the foundational concepts and early proposals.

Writing asynchronous code in C has always been a challenge.

At the Linux App Summit (LAS) in Albania three months ago, I gave a talk about testing in the xdg-desktop-portal project.

A few weeks ago, a bunch of display driver and compositor developers met once again for the third iteration of the Display Next Hackfest.

One of the things I’m working on at Red Hat is HDR support.

The latest alpha of the upcoming Blender 5.0 release comes with High Dynamic Range (HDR) support for Linux on Wayland which will, if everything works out, make it into the final Blender 5.0 release on October 1, 2025.

There are a lot of tangible benefits in using toolbox containers for development to the point that I don’t want to use anything else anymore.

Update Oct. 2025: Things have changed since writing this.

In the previous post we explored all the different ways to develop software on Fedora Silverblue when Toolbx and Flatpak are not enough.

Fedora Silverblue is one of the immutable operating systems.

Sometimes I just want to do a small thing, like creating a blog, and then end up noticing everything is horrible and I should probably start fixing things at the root.
