The article makes a good point, but I would argue its not the whole truth.

A proper (relational) database does more than just storing values. It also stores relations between different values. And SQL is an extremely powerful way of working with those relations. I see the point that the author makes about projects with a database/state being worse, but in some projects I’ve worked on, I’ve been able to offload a great deal of work into the database schema.

And also, a database doesn’t just store a few measly little variables. Often, you’ll be storing gigabytes or more in there. That’s completely infeasible to pass from function to function, or sometimes even hold in RAM at once. The point of a database is to store and manage data, in amounts that you don’t want to have to deal with yourself.

I went for a run, for exercise AND THE GLORY OF THE EMPIRE!

I’ve never used CasaOS, so I can’t help you with that, but I run NetBird for remote access to my homelab. What you’re describing sounds to me like an issue I used to have with Tailscale.

I think NetBird might be trying to route your traffic through a STUN/TURN server to get around a NAT or firewall. A NAT (in case you haven’t heard of it) is a sort of “mapping” from one IPv4 address to many IPv4 addresses. Its used to "make more "addresses, otherwise we would have run out decades ago. (this is a simplification, its actually much more complicated)

The first thing to check here is: Are you behind a CG-NAT? (there’s probably some websites to check this)

If yes, then there is little you can do without setting up a VPS to get around it.

If that’s not it, then you’ll have to figure out how CasaOS handles networking internally. Your services might be behind a NAT inside.

As for ressources/information, I mostly stuck to the official docs.

See my other comment (sorry, Voyager seems to generate weird share links).

While violence at schools does exist in Europe, the numbers just don’t compare to the US.

And don’t forget! The US has stabbings too, its just that you have so many shootings that a stabbing won’t make the news.

Also, what are “grooming gangs”?

That page lists attacks in general, and not just at schools but also universities. Out of the 25 attacks listed for Germany (so since 1990), only 11 are shootings, and 14 have no deaths at all. So, you’re right, Germany does know what school schootings are.

But compare this to a total of 67 (damn that number!) in the same timeframe in the UK ( https://en.wikipedia.org/wiki/List_of_school_attacks_in_the_United_Kingdom ), despite the UK containg about 20 million less people than Germany. Unfortunately, Wikipedia doesn’t have a comparable list for France.

But both of those numbers just cannot compare with the US, where just the school shootings that Wikipedia lists (not all attacks, just shootings) add up to 882 over the same time frame. And its not due to higer population, the US only has about 4 times as many people as Germany.

Sorry, I realise you’re kinda just trying to say, school attacks do happen in Germay too, and you’re right. But you sent me down a rabbit hole. And the number of school shootings in Germany is so low that as a parent you can reasonably assume it won’t happen (and they are rarely big enough to land in the news), whereas in the US it seems to be something that everyone thinks about, that schols plan for, and that has a not inconsiderable chance of happening.

Edit: spelling

Depending on the language, there might exist an automated tool for generating those kinds of diagrams from code.
