After upgrading one of my physical hosts to Debian Trixie, it failed to boot.
It complained about the service for mounting my encrypted disk not starting.

Turns out this is a known problem (even mentioned in the Trixie release notes).
For cryptsetup to work in Debian 13, the systemd-cryptsetup package must be installed:

# apt-get install systemd-cryptsetup

After doing this (via the rescue shell) and rebooting the host, the system started seamlessly.
And the encrypted disks were mounted as expected.

and TIL I can read(1) from a distinct file descriptor to avoid having processes in the shell's while loop consume input from the file I pass.

while read -u 8 f; do
...
done 8</path/to/file

I can use any fd (typically > 2)

On a work computer I'm currently using WSL quite often and thus wanted to see if there is a pbcopy/pbpaste equivalent.
Turns out WSL integrates with the X11 and Wayland clipboard APIs, thus we can simply install wl-clipboard.

With this in place, running wl-paste inside WSL dumps the content of the Windows clipboard.
And echo "foobar" | wl-copy puts "foobar" into the Windows clipboard.

Debian 13 (Trixie) was released yesterday. 🎉

As I refer to the stable repositories in my sources list, the following error is now shown since their release information changed:

# apt-get update

To fix this message (and enable upgrading to the new release!), I use the following command:

...

N: Repository 'http://mirror.iway.ch/debian stable-updates InRelease' changed its 'Codename' value from 'bookworm-updates' to 'trixie-updates'

Afterwards I run the usual apt-get dist-upgrade to upgrade the system to the new Debian version.

Joel Dare explains Why I’m Writing Pure HTML & CSS in 2025.

Pure HTML is evergreen

HTML was invented by Tim Berners-Lee in 1991 as he worked on the World Wide Web at CERN. Some of the earliest examples of web pages are contained in the documentation on the WWW project.

These pages still render in modern web browsers.

I revoked a signing subkey of my GPG key.
The expiry date of this subkey will no longer be updated (as the key is revoked).
But I plan to keep the revoked subkey itself in my public key (so people can still associate old signatures with me).

The pgp-expiry-monitor would now alert for all eternity on the expiry date once it passes.
To avoid this, I now added functionality to read the revocation status of a subkey and skip the expiry date check if it has been revoked.

You can install the newest version of pgp-expiry-monitor from GitHub:

go install github.com/x-way/pgp-expiry-monitor@latest

The Bash trick you need is:

trap 'echo "Exit status $? at line $LINENO from: $BASH_COMMAND"' ERR

In the tmux and gist and trying to make students happier article, Jan-Piet Mens explains how to take screenshots with tmux.

As I still haven't migrated from Screen to tmux, I was wondering if this is also possible in Screen.
And turns out that there is indeed a similar mechanism that can be used in Screen.

By using the hardcopy command, Screen can write the current scrollback buffer to a file.
This can also be done for a detached session:

screen -X hardcopy -h /tmp/myscreenshot.txt

It's also possible to specify an explicit session and pane to use:

screen -p 0 -S 12345.pts-0.rocky -X hardcopy -h /tmp/myscreenshot.txt
