Yep, people are enthusiastic about self hosting and like talking about what they host :)

When I am sending? Well, once things are set up properly I’m pretty confident that things arrive (though nobody can ever be 100% sure of course). I also tend to mail to the same recipient domains a lot, like for work and hobby projects, so once those are tested you get pretty confident.

Unnoticed downtime is usually quickly noticed, I depend on my server for a lot of things. Senders are often resilient enough to keep things in their queue and try a few times. There’s also a fallback MX registry at my (3rd party) DNS host which will queue stuff in case the primary MX goes down.

Interesting hardware list, that indeed is a bit more complicated (and probably more expensive) than most are running.

Nice, RSS is great indeed. I use it extensively as well, but I didn’t even realize it was a thing people ran as a service on a server. I hadn’t heard of FreshRSS etc. I personally just run newsboat from my desktop/laptop, even my phone if need be.

I’ve been self-hosting e-mail for over 15 years and hope to continue doing so. Although it’s being made increasingly difficult by big tech players. I wrote about it here: https://proycon.anaproy.nl/posts/rant-against-centralising-e-mail/

To answer my own question:

• E-mail (postfix, dovecot, rspamd, clamav)
• Web (nginx), various small websites including my homepage
• Fediverse Microblogging (Mastodon)
• Matrix Chat (synapse)
• XMPP Chat (prosody)
• Music streaming (mpd, snapcast)
• Home automation (home assistant and my own lighthome stuff, mqtt)
• IRC bouncer (znc)

And the basics of course:

• SSH (openssh)
• NFS

All running on an Ubuntu Linux server, but everything is containerised into mostly Alpine Linux podman (rootless) containers (and a few lxc containers which I’m phasing out).

Nice, you must be into deep learning with such a setup, any particular reason the deep deep learning models and GPU run in your server rather than in a powerful desktop system? Maybe you’re actively offering AI services to the outside world?

I’m using snapcast, though more as an alternative for icecast to just play my music from mpd, rather than for its more advanced syncing features.

snapserver is on my main server, and snapclient on my desktop PC, my laptop, and on raspberry pi’s connected to main speakers throughout the house. I can start/stop the clients via my home automation system.
