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 …”

Which would be what, exactly?

Literally the next line on the image tells you what:

“This includes: disability, pregnancy/maternity for the purposes of the mobility assistance use case.”

It’s a very flexible language so can find a niche almost anywhere. I know of fintech companies that use it extensively for their back end data processing systems, and I’ve seen some really interesting stuff done with Clojure and Apache Kafka. They’re a good fit for each other - Clojure, as a lisp, is optimised for processing infinite lists of things and Kafka topics can be easily conceptualised as an infinite stream of data.

Also, when combined with Clojurescript, it provides a single language that can be used full-stack, so could drop in anywhere that you might otherwise use Node.

But I think one of the best things about it is the way it forces you to re-evaluate your approach to development. It’s a completely functional language so you have to throw away any preconceptions about OO and finding new ways to resolve old problems is one of the things that should be a joy for most developers, even if it has no practical application.

Give Clojure a go.

It’s a modern variant of lisp that runs on the JVM and has deep interoperability with Java, so you can leverage your existing knowledge of Java libraries.

But as it’s a lisp, it will have you thinking about problems in a very different way.

DigitalOcean’s guides in general are pretty good for all sorts of things, whether it’s a generic discussion of a concept like the ones you’ve posted, or a step-by-step guide for installing and configuring specific systems or software. Even if you’re not using DO as a host, much of what they suggest is still very useful.

systemd [is] a niche

Maybe in the wider world of all the operating systems installed on all the computers, but for Linux-based computing it is, like it or not, near ubiquitous these days. And in particular for server systems (and this is, after all, /m/selfhosted), good luck finding something that isn’t systemd-based unless you’re deliberately choosing a BSD or aiming for a system which has ever-decreasing amounts of support available.

what if I’m not using CoreOS?

Podman runs on any distro (or more strictly: any distro that uses systemd). It’s essentially a FOSS alternative to Docker.

There is a long abandoned (but it still runs) project called eDEX-UI (https://github.com/GitSquared/edex-ui) which basically provides a working, useable terminal surrounded by all sorts of the crap visual appearance of hacker terminals in the movies. Pair that with a terminal editor and you’ve almost got a movie IDE!

It’s kinda fun for a while although I’d be amazed if anyone actually used it as their main terminal emulator program. But you could.

I haven’t run up my own Threadiverse server yet, but I self-host my own one-person Mastodon, also on Hetzner. Yes, it will eat up a lot of disk space, so if you’re trying to keep costs down you need to send all the media to S3-compatible storage. I use Backblaze B2 which costs me something like $2/month for 200GB of Mastodon media.

I would assume Lemmy or Kbin would also be greedy for asset storage, as they’ll pull in media (images and videos) for any community you follow. So again pushing that all off to a low-cost storage system such as S3 makes a lot of sense.

The developer of kbin, @ernest, has said that automated processing of account deletion requests is on the roadmap but currently it’s a manual process.

As you can imagine, for a piece of software that two months ago was in alpha status with fewer than 100 regular users and then suddenly became one of the most-used systems on the Fediverse, there are still a lot of rough edges to be cleaned up.

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.

CPU requirements for Lemmy hosting are minimal. Memory is useful - you’d want to use the Pi 4 with either the 4GB or 8GB RAM, anything less than that will work but you’ll be running the risk of difficulties if the server gets busy.

You’ll also need plenty of storage, especially if people are going to start uploading media to your Lemmy host. Given that a Pi runs off an SD card you might well find yourself running out of storage space - I’d recommend attaching a USB storage device for the reassurance in that respect.
