Honestly I think if there is a hope for greater detach from “The Cloud” more broadly, it’s a testament to nextcloud that folks that don’t even know enough to know what DB they are running are able to run a server, and host things well enough to consider themselves users.
This statement brought was to you by someone that set up nextcloud and had no clue what DB it was using.
The idea that manuals in linux are a good way to learn and understand new software is peak linux neckbeard bs, and I will die on this hill. I congratulate OP on the exact type of autism that lets them feel this is an effective and useful method for learning new software, but if there is desire to have a greater adoption of linux maybe its bad to be snarky at folks for not instantly understand the terminal based documentation conventions of some dudes in the 70s. Maybe an alphabetical* list of all possible options is okay for referencing or searching, but is objectively insane way to learn or understand a problem.
I think they mean “Verhältnis” (google says ‘relationship’) doesn’t really mean ratio, but ratio is what we use in english.
