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.
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.
You may have to buy the necessary brain upgrade from your brain dealer, but generally multiple languages fit yeah 😉 It may get a bit confusing if they're very similar languages though, although I also find that that may help in retention of vocabulary.
I speak dutch (native); english (fluent); german, spanish, portuguese, french, esperanto (good); italian (adequate); russian (slightly below adequate); mandarin chinese (basic); arabic (very poorly)
I'm learning mostly russian and chinese, for many years already, but not in any formal setting and with for many years already. I like reading books in the other languages to keep them up.
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.
I'm currently reading The Metamorphosis of Prime Intellect, by Roger Williams... It's scifi about "the singularity", albeit a bit graphic and disturbing.
I recently finished reading "Arrête avec tes mensognes" by Phillipe Besson (english title: Lie with me), a gay novel, and that was a great read.
PlantUML for drawing all kinds of diagrams based on formal text descriptions (online version: https://www.plantuml.com/plantuml/uml/, but mainly just an offline tool). I'd encourage people not to use online services for everything but simply rely on good tools.
Freesound.org (https//freesound.org) for sound fragments
You can just use plain todo.txt. I wrote an extension for it as well, but it's a bit niche for a certain type of users: https://proycon.anaproy.nl/posts/todo/
