Hi there! 👋 I am a Linux 🐧 system and security engineer interested in safe programming languages 🦀 and container focused operating systems 📦.

I am currently a member of the CoreOS team at Red Hat, working on Fedora CoreOS and Red Hat Enterprise Linux CoreOS.

CoreOS systems are all about running containers at scale with Kubernetes distributions (OpenShift, OKD, Typhoon) or on a single server with podman and quadlet.

See talks about Fedora CoreOS and CentOS Stream CoreOS.

I am a maintainer of the Fedora Atomic Desktops. They are container focused desktop operating systems based on rpm-ostree/bootc, podman and Flatpak. I primarily maintain the Silverblue and Kinoite variants which respectively feature the GNOME and KDE Plasma desktops environments.

The Fedora Atomic Desktops are also the base for the Universal Blue images (Aurora, Bazzite, Bluefin) that include drivers (NVIDIA), codecs and other changes that we can not include in Fedora, generally for legal reasons. I recommend giving them a try if your hardware requires this kind of support.

See talks about Fedora Atomic Desktops.

Fedora Atomic Desktops systems (Silverblue, Kinoite, etc.) use Flatpaks to make graphical applications easily available to users. I am part of the team that maintains the KDE applications Flatpaks in Flathub. I am also looking at packaging the missing ones and improving the integration in KDE Invent and KDE development in general.

See talks about Flatpaks.

To make it easier to run various popular distributions with toolbox or distrobox, I have created a community maintained repository to share the maintenance of container images: toolbx-images. See Community maintained images for toolbox (and distrobox) for more details.

To be able to safely extend CoreOS and Atomic Desktop systems without resorting to package layering or derivation, I am working on creating systemd system extensions (sysexts) for various common use cases. Those sysexts are currently experimental and unofficial, but should be usable and stable. See the fedora-sysexts repo. I am also working on a more ergonimic user experience for managing those sysexts with the sysexts-manager project.
