What I’m looking for is a way to take backup of Docker containers so I can restore them in case things go wrong. Doing so with VMs is so easy. If nothing works, I’ll make an image of my OS disk. Unless some benevolent self hoster tells me a simple way, which was my hope when posting here :D

Last year I wanted to set up a budget media PC and got enamored by this video: https://www.youtube.com/watch?v=WCDmHljsinY

I got a 600 G3 with the 4560 processor, installed Debian onto it and hooked it to my 4k TV mainly to run immich and stremio.

Immich runs just fine, though I have gotten too fast behind its upgrades and having less knowledge about Docker, I’m afraid to update immich. Need to figure that out.

But what disappointed me was that my good quality videos (even the downloaded ones) are choppy to run (unlike the fluid expectations from the video above) and I don’t really know what I should look into to make it better.

I’ve wondered for a long time if it is possible to use WiFi as broadcast/multicast? I mean, i understand that it won’t work out of the box, but if one was to write code from ground up (ie different TCP protocol) can it be made possible to, say, transmit video lecture from one WiFi router and for multiple mobile phones to receive and view it without individually being connected to the network. Kind of like how everyone is able to view the SSID of the WiFi node without being connected.

Or is it a hardware level problem that I can’t wrap my head around. I have wanted to understand this for a long time but I don’t have a background in this subject and don’t know the right questions to ask. Even the LLM based search tools have not been of much help.
