A collection of shorter thoughts, quick updates, and things I’ve learned that don’t warrant a full blog post.
Plausible writes error logs only into its Postgres database. Errors are in the errors column of the oban_jobs table.
In Helldivers 2 you can cause the Pelican to launch itself in the air upside down by calling in a support weapon right under the wing. On impact the Pelican will go flying in the air and land in a random spot.
You can run systemctl show servicename.service to get the “final” version of your systemd service file, including all overrides which would typically be loaded dynamically by systemd itself and not visible in the actual unit file. This is extremely helpful on NixOS where packages can sometimes re-use upstream systemd unit files and inject NixOS specific options through an override file.
Git credential helpers work via writing and reading from standard input and standard output which helped me debug an issue I was having with pass-git-helper. To get a credential helper to spit out the password, invoke it with the get action and pass in some basic key=value data. The interaction looks somewhat like given below, with < indicating the standard input of the credential helper and > indicating its standard output. ...
After a GNOME related NixOS rebuild sometimes the secret store starts erroring out with this message: No such secret item at path: /org/freedesktop/secrets/collection/login/145 This is resolved by restarting the gnome-keyring-daemon using the command gnome-keyring-daemon -r -d.
Hades and Hades_2 are written mostly in Lua and all the code is left as-is in the game which makes modding significantly simpler. Very cool!
Helldivers 2 on Linux hates full screen mode and will fail to start the next time after you switch display to full screen. This is why it breaks randomly for me on Linux and seemingly gets fixed after an update since Arrowhead randomly reverts back to windowed when the game is updated. Work around is to always use Borderless instead.
rclone can use HTTP hosts as a remote, so it’s often faster and easier to move things between servers via a file-server rather than over SSH using rsync assuming the contents aren’t private.
Nix remote builds are run through the daemon (obviously) so they are executed as root on the host delegating builds. To prevent issues, nix store ping needs to be run as root first to verify the host key before Nix can start using the remote host to do builds.
pw-cli list-objects | rg node.name will give you a full list of all connected audio inputs and outputs on a PipeWire system.
