Palladium

since when is Palladium a REE?

You mean server? If so, the server is also open source

That is what i meant. It is OSS but not FOSS because you need a key to start it.

Bitwarden has a FOSS client app and FOSS server apps exist (though the default service is not FOSS).

Syncing 2FA keys brings the danger with it that you accidentally sync the key to the device that is used for the first factor thus making it not 2FA anymore.

trains are actually one of the examples where you can get away with lower energy dense fuels, like methanol, ammonia or even compressed hydrogen. sure the range will go down, but for many connections this will not matter that much because it will still be possible to go 1000km with one tank if needed.

Martian soil contains significant amounts of perchlorates. So yeah this is probably not gonna happen unless they figure out how to make moss resistant to perchlorates.

If they are all installed in the same wine prefix you could back up everything in one go by archiving the “.wine” folder in your home. that will include all applications installed in wine and all settings for those applications.

if you want to separate them into one archive per app you should look into wine prefixes, otherwise you would need to identify every folder a given app created during installation and archive those together manually, which can be very tedious.
