I have a TV which says it supports 4K 144Hz and right now I run an old laptop as a media server/desktop to it, which can only handle 1080p. I wish to switch to some NUC/mini-pc that run a linux desktop in 4K and run media flawlessly on it.

There are two things that I get confused about trying to find something that suits my wishes:

1. How do I properly find out if the hardware can handle this? Like a rpi5 can handle 4K video playback with like librelec, but a 4K desktop distribution is laggy and slow. Is a CPU only enough, or do I need dedicated GPU? Should I be looking at the Ultra Core series from intel, does it have good linux support?
2. Are my wishes on hdmi 2.1 level troughput? Which may not work on linux? Reading about hdmi 2.1, then it says that the hdmi forum forbids open source support for hdmi 2.1, does that mean there are binary blobs for linux that will work?

Is there anything else I'm missing? If you run a linux media server, what hardware and dist are you running?

Rikspolischefen gästade SVT och talade om vad man bör göra om man som förälder hittar Signal på sitt barns mobil. Tydligen ringa polisen

Eftersom appen inte har något normalt användningsområde -- utanför beställningsmord, som var ämnet -- så blir jag själv lite rädd. Jag har en hel kontaktlista med mördare i min telefon då! Hur har jag hamnat här? Är jag själv mördare? Bäst jag ringer polisen på mig och alla mina vänner

Det är fruktansvärt hemskt att en person på en sån position är så oförstående kring teknologi.

Hi,

I'm looking for some way to send my own alerts via e-mail in some way. Whenever I try to search for this, most docker images have a much grander goal, and I have a hard time understanding how to use them for my purpose.

What would I want? It'd be nice to have a docker running some smpt-server (I suppose), so that I can make my own python script that scrapes a website, looks at some metric, and e-mails me whenever whatever I'm looking for is found. I only want it to be available on and to receive mails from localhost, no dns, just forward e-mails to my personal one, no web-interface, etc.

I'm quite new to self-hosting, but I hope you still understand what I'm looking for. Is it possible? Should I look for another solution? Will this not work? Any help/input very much welcome.
