3 days agoThere is not one single technology to be good or bad at. You can be an Android development ace, a Windows gamer and a Linux user all at the same time, and naturally you will struggle if you switch to Windows dev and Linux gamer.
Being tech savy really just means that you know and recognize tons of patterns that pop up everywhere (e.g. drag-n-drop, config files in certain places with overrides in other places etc.)
You cannot selfhost Signal, because the regular app won’t connect to your server. You could probably bridge it to Matrix I guess? I’m pretty sure it’s a thing, but I see little benefit here, besides your phone not connecting to Signal and your messages being collected in one app, if you so desire.
