That is largely a myth and in my experience never happens with higher quality laptop batteries. But yes limiting charge doesn’t hurt if it is only used as a UPS anyways.

Why remove the battery when it is a perfectly working built in UPS?

You kindly ask the maintainer of the container repository to add major version tags ;)

Yeah, works great in my experience, but requires a bit of care if the upstream container packager is only doing a “latest” tag and not major version tags that are unlikely to break compatibility.

Because that is not its intended function. If you want that just use Easy Sync with Nextcloud or another WebDAV server.

Configuring a Redis cache really helps in my experience.

But I also recently noticed something odd: it works quite well on my usual internet connection, but when I traveled abroad it became excruciatingly slow, more so than the admittably worse mobile connection would have let me assume. Something about it seems to require a relatively stable internet connection on the client side it seems.

1. Yes, but NTFS is a bad filesystem, so I would format it anyways.
2. What are docker drives? Docker works on any normal Linux distro. Some commercial NAS are *BSD based though and there you need to use some ugly workarounds.
3. Usually the fans make the most noise as NAS cases are optimized for heavy drive use and thus use a lot of ventilation. If you are a typical home user you might be better off repurposing a small form factor quiet media PC, but look for one that can fit the drives you want.
4. Same as a regular PC. If the NAS is using standard software raid or btrfs/zfs then yes, with hardware raid no (avoid!).
5. There are many different ways with different pro and cons. It really depends on what you want.

Right 🤦‍♂️ It has been a while. I corrected it in the original post now.

I remember from back in the day that you need a "twisted pair” edit: ”cross-over” cable though, or do modern ethernet ports automatically adapt to that now?

For a/v calls yes. You might need to configure a STUN server to help clients find each other if they are behind a NAT.

Currently xmpp voice and video calls are not going through the server at all, so it will work just fine on a RPi3.

No problem at all. Both Prosody and Ejabberd will work, but Prosody probably a bit better. Maybe see if https://snikket.org (Prosody based) has the right Docker images for that arch, but I think it does support ARM64.

Get an old laptop and install https://yunohost.org/ on it. Learning by doing is the best.

Is fairly easy and you might end up preferring XMPP over Matrix anyway ☺️

If you have some services for monitoring your main server like a Grafana/Prometheus setup that might be interesting.

You could also use it for storing backups as in the 3-2-1 backup strategy.

Cockpit has a nice integration for Podman containers.

https://gotosocial.org/ currently seems to be the popular choice for mastodon compatible single user instances that are easy to setup and run.

Personally I run a https://akkoma.social/ instance, which works fine, but it is a bit more complex to setup and requires a lot of customization to look nice.

Hmm, maybe it is possible, but Snikket is quite opinionated and you need to keep in mind that the XMPP server also needs direct access to the TLS certificate as it isn’t only using port 443.

Maybe it will be better to just use Prosody (or Ejabberd) instead then.

Yes to both. Check out https://joinjabber.org
