  • Okay, you may not gonna like it but I rented a 1TB storage box from Hetzner for 3 euros a month, just to get that foot off my neck. It’s omega cheap and mountable via CIFS so life is good for now. I’m still interested in what I described in the OP, and I even started scribbling some Python, but I’m too scared of fucking anything up as of now.

    The annoying part in writing that script was discovering that the filenames on disk don’t match the filenames in the URLs. E.g., given this URL:
    https://lemmy.org.il/pictrs/image/e6a0682b-d530-4ce8-9f9e-afa8e1b5f201.png. You’d expect that somewhere inside volumes/pictrs you’d find e6a0682b-d530-4ce8-9f9e-afa8e1b5f201.png, right…? So that’s not how it works, the filenames are of the exact same format but they don’t match.

    So my plan was to find non-local posts from the post table, check whether the thumbnail_url column starts with lemmy.org.il (assuming that means my instance cached it), then finding the file by downloading it via the URL and scanning the pictrs directory for files that match the exact size in bytes of the downloaded files. Once found, compare their checksums to be sure it’s the same one, then delete it and delete its post entry in the database.

    When get close to 1TB I’ll get back here for this idea… :P









  • Love me some systemd timers. Much more fun than cron.

    • Sane handling of environment variables with EnvironmentFile=
    • Out of the box logging. Especially useful is the ability to journalctl -f to watch long-running processes, which I’m not sure whether possible with cron
    • The ability to trigger the service manually rather than setting the timer to * * * * *, then forgetting it’s supposed to run in a minute, get distracted, come back in 15 minutes

    My only complaint is it’s a bit verbose. I’d rather have it as an option inside the .service file. The .timer requires some boilerplate like [Unit].description (it… uh… triggers a service. that’s the description), and WantedBy=timers.target. But these are small prices to pay
