Recently in Spain we have suffered a complete power outage, with no electricity for a long time. Some were able to have power on their computers with generators, solar panels, etc. And I know you can have data connectivity with SDR or HAM radio. But my question here is, what are some good self-host/local offline software that we can have and use for when something like this happens. I know kiwix, and some other for manuals. Please feel free to share the ones you know and love, can be for any type of thing as long as it works completely offline, I don’t search for any specifics, if it is designed for offline use, just name it. For GNU/Linux only please (using Arch myself BTW). Thanks in advance.
Realistically, most self-hosted services will work “offline” (no internet connection), provided you also power a local network during the outage as you will have to access it somehow.
This also plays into the other factors, as self-produced power is usually far less than what you’d get from the grid (I.e. you’ll probably want to avoid things like heavy transcoding).
