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, just name it. Of course for GNU/Linux (using Arch myself BTW). Thanks in advance.
One I’m using a lot is a self hosted password manager. Vaultwarden specifically. Useful for more than just passwords of course, can take secure notes as well. I keep it locked to my local network only, and need to VPN in to my home network when I’m out to access it.
