usbmon turns Wireshark into a cable tester, and finds retransmissions on cables that supposedly work.

Quadlets describe a container as a systemd unit, so systemd owns the lifecycle instead of Podman.

Ostree is not just for Silverblue. Using it as a content-addressed snapshot store for your own files.

Swapping the Flatpak Mesa runtime for mesa-git so a new AMD card stops falling back to software OpenGL.

Setting up a two-disk BTRFS RAID1 for a Steam library, and repairing it when a drive starts throwing errors.

Flatpak makes the host distribution almost irrelevant, down to proprietary codecs and games on musl Alpine.

podman generate systemd plus an autoupdate label: containers that start on boot and update themselves.

Getting Podman onto cgroups v2 and crun on distributions that still default to cgroups v1 and runc.

Why an atomic rpm-ostree desktop stuck: updates that check out like git, and roll back the same way.

Alpine can commit changes back onto its own live ISO. Using LBU to build a persistent maintenance drive.

Moving a password store between pass and KeePass, and getting two YubiKeys to guard all of it.
