  • It’s a little more than 100€

    It’s half as much again! If your budget is that flexible you really should have mentioned it in the original post so that people could give you a wider range of options.

    Translate it up by a couple of orders of magnitude and you get “I want to buy a car, I have €10,000 to spend” … “I found one for €15,000, it’s a little bit more but …”




  • Not really a viable solution for many scenarios though. What if your PDF has half a dozen pages, your answer becomes really tedious. And in a lot of cases a PDF with forms is expected to be sent back to the person or company that created it once the fields have been filled in. They’re not likely to want to receive a bunch of JPEG screenshots instead.




  • I’m still struggling to understand what advantage Docker brings to the set-up.

    Maybe the application doesn’t need to write anything to disk at all (which seems unlikely) but if so, then you’re not saving any disk-write cycles by using docker.

    Or maybe you want it only to write to filesystems mounted from longer-life storage e.g. magnetic disk and mark the SD card filesystems as --read-only. In which case you could mount those filesystems directly in the host OS (indeed you have to do this to make them visible to docker) and configure the app to use those directly, no need for docker.

    Docker has many great features, but at the end of the day it’s just software - it can’t magic away some of the foundational limitiations of system architecture.










  • Yes, it matters hugely.

    Let’s say I do a google search for “how to frobitz a widget” and the top result (because as you say it’s in Google’s cache) points me to a post on /r/WidgetFrobitzing.

    I then click through and find that the post is deleted or has been changed to say “lol Spez sucks use Lemmy” or whatever. I’ll almost certainly close that tab and go back to google to find another link. That deprives Reddit of clicks through its ads, of time spent on site, and it also means that user is less likely to follow links to Reddit in future as they will know they’re not as useful as Google thought they were.




  • I can’t help with Lemmy, but I’ve been running a single-user Mastodon instance for almost a year now.

    Like you, I found that the media very quickly used up much more disk space than I anticipated. There are a few things you can do.

    You can tune how long media is stored for: some of this is done in the admin interface, but really you need to set up cron jobs to regularly run various tootctl commands. This is the crontab I use:

    SHELL=/bin/bash
    PATH=/home/mastodon/.rbenv/shims:/home/mastodon/.rbenv/bin:/usr/local/bin:/usr/bin:/bin
    
    RAILS_ENV=production
    # Remove media attachments older than 8 days
    11  19  *   *   *     cd /home/mastodon/live && time bin/tootctl media remove --days 8
    # Remove link previews older than 28 days
    22  5   *   *   *     cd /home/mastodon/live && time bin/tootctl preview_cards remove --days 28
    # Remove files not linked to any post
     3  23  *   *   0     cd /home/mastodon/live && time bin/tootctl media remove-orphans
    # Prune remote accounts that never interacted with a local user
    44  1   *   *   *     cd /home/mastodon/live && time bin/tootctl accounts prune
    
    

    You can of course choose even stricter settings but I found that no matter what I did, given that I am following approx 1,000 other Fediverse accounts it still used up more disk space than I was comfortable with.

    So I offloaded most of the media storage onto an S3-compatible service. It’s breaking the self-hosting ethos somewhat, but with Backblaze B2 I can happily store and serve several hundred GB of media files for just a couple of dollars a month. To me, that was a no-brainer.
