Since I have been using Icinga DB (instead of just PostgreSQL) as the backend for my Icinga2 instance, it has happened to me twice that Icinga no longer worked correctly after an update of the Icinga DB package. On closer inspection, it also becomes clear why:
× icingadb.service - Icinga DB Loaded: loaded (/lib/systemd/system/icingadb.service; enabled; preset: enabled) Active: failed (Result: exit-code) since Wed 2025-01-22 21:42:50 CET; 27s ago Duration: 13ms Main PID: 1853805 (code=exited, status=1/FAILURE) CPU: 13ms Jan 22 21:42:50 monitor systemd[1]: Starting icingadb.
I recently refurbished a used and old Acer Aspire E774 laptop as a donation for the Computertruhe e.V.. Of course, this also involves overwriting the hard disk with random data so that old data can no longer be reconstructed. Because “deleted” is not the same as “securely deleted”. I used the shred tool in a Fedora Live environment for secure deletion. However, it works just as well with any other Linux distribution.
Two things are usually in short supply when you run a Mastodon instance: Funding and public attention. But both are important so that the instance can continue to operate and - if desired - achieve growth or reach.
My goal with metalhead.club is to offer a professionally hosted platform for everyone who feels at home in the metal music genre. In order for such a theme-based instance to be viable and its users to benefit from it to the greatest extent, it must achieve a certain level of popularity.
Since the user flood of November 2022 I’ve been using Scaleway’s S3 storage for media file caching and storage of my metalhead.club Mastodon instance. It was easy to set up and has been working reliably for me. Back then the media cache size increased so much that my server’s internal storage could not keep up with the increasing demand. I didn’t want to shrink down the cache duration too much and therefore left it at 14 days.
