Linux crontab shortcuts

With cron, you can use some shortcuts that let you see when an entry is triggered without remembering the more difficult numbers that you would have to put there:

Synonym        Meaning and equivalent crontab values
-----------    ---------------------------------------------------
@reboot        Run once, at startup (only works with this synonym)
@yearly        Run once a year, equals "0 0 1 1 *".
@annually (same as @yearly)

Razer Book 13 with Debian Bullseye: Fix Audio Problem

The Razer Book 13 is my second Razer notebook. The fine silver makes a nice difference to the beautiful black of the Stealh 13. Even though the technical specs leave some wishes open as 16 GB of RAM is the max, the look and touch is great. In my opinion this is the most beautiful non black notebook available in 2022.

Audio may not work out of the box though when you install Debian Bullseye (11) on your Razor Book 13.

When your output lists only the Dummy-device, fix that with the following command (run as root):
