The tool presented here, „Simple Apt Update“ (simple-apt-update) is nothing more than a front-end to the non-interactive execution of apt-get update|full-upgrade and apt list –upgradeable. It can look like this:

Utility to search for XDG Desktop Files
3. November 2024 in Administration, GNU/Linux, Programmierung, Technik.
In my previous article Print XDG Desktop Definition for Application i described a way to search the various „applications“ sub-directories of the known XDG data directories for .desktop-files that match certain search criteria.

Getting Alerted on Expiring GPG Keys
3. August 2024 in Administration, GNU/Linux, Programmierung.
GnuPG is a powerful cryptographic tool that enjoys widespread support by F/LOSS mail user agents. However, due to a lack of conventional public key management it is plagued by key-related issues. One such issue is the expiry of GnuPG keys, which often goes unnoticed by affected messaging partners until such time when it actually disturbs […]
Installing r10k on a Foreman Server
4. August 2024 in Administration, GNU/Linux.
The following occurred to me on a recent version of Foreman (i used 3.9) on a recent version of Red Hat, Alma or Rocky Linux 8 (i used 8.9).

PiKVM on an OrangePi Zero 2
3. November 2023 in Administration, GNU/Linux, Technik.
The OrangePi Zero 2 H616/1GByte is capable of running PiKVM. I find this an interesting development, because if i only want the KVM functionality, a full-blown Raspberry Pi 4 with all its CPU resources, multiple Gigabytes of RAM and peripheral devices seems somewhat of an overkill. I am aware that the latest official PiKVM, the […]

If you are […]
