sudo rm -rf ./ and sudo rm -rf . are, as far as I know, the same command. Did you mean that you dropped the . and ran sudo rm -rf /?
Fortunately for me, this never happened to me, but I have gotten pretty close to running rm -rf ~ after mistakenly creating a directory caller ~…
About Digi, here in Portugal it’s a bit iffy. Sometimes calls don’t arrive, mobile data doesn’t work in the subway, along with some other nitpicks, but it’s definitely gotten better since I started using it. I get unlimited data for fairly cheap which is cool.
It’s not like I need to be connected to the internet at all times, so my biggest peeve is definitely the fact that for some ungodly reason whenever I stop getting mobile data I need to fully reboot my phone to get it back again. Turning mobile data on and off, or setting airplane mode on and off doesn’t work for some reason.
But something to take into account is that (and this is purely anecdotal) coincidentally the moment I started using digi, I started getting spam calls en masse, specifically from Iberdrola. Most of the time once a day, but at some point it reached multiple times a day. I never answered, but would search the number online and see that it was spam. Though it could very much have been a coincidence, it still makes digi feel a bit sus to me. Rarely do I ever use it without a vpn.
