Pipewire Easyeffects with RNNoise on Debian 12 / Bookworm

RNNoise for removing background sound on your microphone is not included in Debian 12, due to licensing issues around its training data. The least painful way to work around this is to install the Easyeffects Flatpak instead of the packaged easyeffects:

sudo apt-get install flatpak gnome-software-plugin-flatpak
sudo apt-get remove easyeffects
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install flathub com.github.wwmm.easyeffects

Gnome Night Light from Sunrise to Sunset, without Location Services

Set latitude and longitude manually (coordinates shown are for Frankfurt, Germany: 50° 6′ 38″ N, 8° 40′ 56″ E):

gsettings set \
  org.gnome.settings-daemon.plugins.color \
  night-light-last-coordinates '(50.0, 9.0)'

Revisiting ratarmount

Since my previous look at ratarmount, it went from 0.6.3 to 1.0.0, had the most interesting developments and now mounts archives via HTTP:

virtualenv ~/.local/ratarmount
~/.local/ratarmount/bin/pip3 install -U ratarmount[fsspec]
~/.local/ratarmount/bin/ratarmount
install -D ~/.local/ratarmount/bin/ratarmount ~/bin/

ratarmount -f https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.13.4.tar.xz ~/mnt

Prioritizing own NTP servers for systemd-timesyncd

# cat /etc/systemd/timesyncd.conf.d/timesyncd-corporate.conf 
[Time]
NTP=ntp1.example.com ntp2.example.com ntp.ubuntu.com

Test if text is empty (even if it does contain a linebreak)

Good job by: https://unix.stackexchange.com/q/386499/2028

if ! grep -q '[^[:space:]]' "${file}"; then echo "Text is empty"; fi

Watch for changes in the Gnome registry

(To reproduce manual changes, for configuration management.)

dconf watch / # (Sorry, thats all)

Trigger Debian/Ubuntu unattended-upgrade

(For testing configuration changes)

rm /var/lib/apt/periodic/*
systemctl start apt-daily.service 
systemctl start apt-daily-upgrade.service

And remember:

tail -f /var/log/unattended-upgrades/*log

Set X11 keyboard layout manually and temporarily (e.g. in i3 if I need to test exotic window managers for my users)

setxkbmap -layout us,us -variant altgr-intl -option caps:none

Speaking of which, set keyboard layout permanently in Gnome

gsettings set org.gnome.desktop.input-sources sources "[('xkb', 'us+altgr-intl')]"

Check if Gnome Screensaver is active (I use this for automated time tracking)

busctl --user call org.gnome.ScreenSaver /org/gnome/ScreenSaver org.gnome.ScreenSaver GetActive

Urlwatch for a new package version in an APT repository

After a long wait, I was finally able to find another use for my awful Perl one-liner from 2019 that pivots a Debian Packages.gz into a space-separated table!

---
name: "Pop!OS Firefox package"
command: curl -s http://apt.pop-os.org/release/dists/jammy/main/binary-amd64/Packages.gz |
  gzip -dc | perl -ane 'if($F[0]=~/^Package:/){$p=$F[1]};if($F[0]=~/^Version:/){$v=$F[1];print"$p $v\n";}' |

diff_filter:
