  • I switched to rspamd. Its bayesian filter is a little weird. It only started working ok after I found the right amount of mails to feed to it. For some reason it forgot everything if I gave it too many mails. I think it’s a Redis thing. No idea. I don’t have the brain power to figure it out or write a proper bug report. But I think my Debian version is outdated anyways, so this might be fixed by now.

    For my server learning from mails from the last 50 days was the sweet spot. Since then I got no false positives and only the occasional false negative. Exactly how I want my spam filter to be.



  • In general you backup everything that cannot be recreated through external services. So that would be the configuration files and all volumes you added. Maybe logfiles as well.

    If databases are involved they usually offer some method of dumping all data to some kind of text file. Usually relying on their binary data is not recommended.

    Borg is a great tool to manage backups. It only backs up changed data and you can instruct it to only keep weekly, monthly, yearly data, so you can go back later.

    Of course, just flat out backing up everything is good to be able to quickly get back to a working system without any thought. And it guarantees that you don’t forget anything.












  • I recently read my German grandma’s memoirs. During the war she signed up to help in Nazi occupied Minsk. Of course for the Nazis “help” meant ensuring the local newspaper printed propaganda. And beforehand they were instructed to be harsh with the “dumb Russians”.

    She once got into trouble because one serial story in the newspaper tended towards a revolutionary message. Apparently the translator didn’t care for the story so he stopped reading it and just let it get printed as he received it. At least that was his official excuse.

    Anyways, of course she grew closer to some of the locals. And of course not every single one of them could help with sabotaging the occupiers. So it was extra sad when she eventually had to flee from the approaching Russian army (a day after the officers loudly proclaimed at a Nazi party that they were about to win the war) and had to live with the knowledge that the Russian’s she left behind were all likely to be executed as collaborators.

    She couldn’t take them with her because the Nazis would likely kill them for being Russian. Or at the very least put them into concentration camps. And she already knew they were bad, just not how bad.
