  • If the container instructions say to set the TZ variable, this means that they bring all the necessary timezone information (for all timezones around the world) with them inside the container. For Alpine Linux, this would be the 1.5 MB (uncompressed) tzdata package.

    If you are instructed to link to those files on the host system, the container usually doesn’t come with the tzdata package and the only way for it to use your timezone is to use the information from the host system by mounting the 2 files.

    However, if you don’t mount these files, the container will usually run in UTC and won’t observe DST. So, all the times in log files and everything regarding time will be in UTC.

    There was one where the guy behind it went to massive lengths so people couldn’t easily distinguish the example files by other means than audio quality. Verdict was that people with more expensive equipment even preferred the sound of the MP3s (320kbps). I think it was this one (Links to Parts 2 and 3 at the bottom.).

    Somewhere else I’ve read that - for most humans - 256 kbps MP3s encoded with VBR-ABR using a high-end encoder are basically indistinguishable from the lossless original. Even at 192 kbps it’s still more hit&miss than it should be. But I don’t remember where I’ve read that.




  • Grafana and Prometheus are great if you have numeric things you want to monitor. CPU usage, RAM, disks, throughput, etc. You can then do lots of things with these numbers, mainly compare them to your other systems or alert when they go out of bounds.

    However, I very much prefer Zabbix for my home network monitoring as this is not so fixated on numbers but can easily work with e.g. error messages in logfiles and alert on those. Or I can regularly check a website for new firmware versions and alert once the latest version changes. There are also lots of ready-to-use templates available from their Community Hub.
