Used to be “oh, I want to do something with computers and programming”.

By now that’s solidified into either some sort of sysadmin, or something in the field of designing microprocessors.

I’m also considering instead training to become an ATC after I’m done with my CS degree.

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

If you live in the Styx

The Styx as in … the mythical river that runs through the underworld? Yeah, I can see that being a low crime area…

(Sorry, european here, if you meant someplace in the US, I’ve never heard of it)

There is no faster plan.

The only alternative would be internet over 4G, which is supposed to be faster, but the mobile connection at home is so unreliable, it wouldn’t be worth the added cost.

I live a couple of houses down a driveway, so laying a new cable is too expensive to justify for just a few houses. This means I get to live with a cable that’s half a century old, and me and my neighbours (and others) are excluded from the recent local fiber internet initiative. Some neighbours just use Starlink, but my hatred of Elon and the sheer stupidity of using satelite internet in central Europe are stopping me.

And, while I do live in a small village, I also have friends in Düsseldorf and in Berlin with even worse internet connections.

I’d love to just switch to a faster plan. But mobile just doesn’t work here, and I’m not giving money to Elon, so … there is no faster plan.

No, you underoverestimate the internet speeds in some parts of Germany. I get maybe 11 Mbit/s on a good day, about 5-6 Mbit/s average, and less if anyone else in the house is using it. And yes, that’s Mbit not MByte.

According to Wikipedia, the slowest Blu-Ray speed is 36 Mbit/s, so about six times my average download speed. And Blu-Rays can go up to 576 Mbit/s.

Well, in English, UTC is an acronym for Coordinated Universal Time, and in French its Temps Universel Coordonné.

Now you may have noticed that neither of those actually makes UTC. This comes from a previous naming pattern for universal time (UT1, UT2, …) (see https://en.wikipedia.org/wiki/Coordinated_Universal_Time ).

Well, if its unbreakable, then its either snake oil, or some variation on the one-time-pad (really depends on your definition of unbreakable).

But having read the article, this is definetly snake oil.

I have a number of things running in the background after booting, so here’s some numbers for you:

• Steam: 1.1GiB
• Firefox: 1 GiB
• Discord: 500-600 MiB
• SchildiChat (Matrix Client): 300 MiB
• KeePassXC: 180 MiB
• KDE’s System Monitor (which I am using to get these values): 140 MiB

In addition to that, there’s always a number of systems services, most of which use a negligible amount of memory, but here’s some I’m just picking out because I recognize what they do:

• plasmashell (KDE Plasma): 380 MiB
• kwin_wayland (also KDE Plasma): 70 MiB
• Syncthing: 80 MiB
• kdeconnectd: 30 MiB
• pipewire: 7.5 MiB (though there are some other processes associated with pipewire in addition to the main one)
• systemd-logind: 1.8 MiB
• systemd: 3.7 MiB
• cupsd: 2 MiB
• XWayland: 45 MiB
• Xorg: 40 MiB

Of course, these are just a snapshot of the systems state, and can only really give you a very rough idea of how much memory something might use at one point in time.

If you want to make your board game more complicated (probably not, but I like the idea, so I’m just throwing it in here), you could use it as an opportunity to teach virtual memory, segmentation, paging and internal vs external fragmentation. Maybe players get certain processes with memory requirements and have to fit them into their own main memory, and whoever can fit the most processes wins, or whoever cannot allocate memory for a new process looses. (I’m just writing down what’s coming out of my head, I don’t want to hijack your game idea, sorry.)

If you run your services off of a homelab rack that dims the lights whenever you power it on

If you are in this situation, then you definetly should get some more power, or at least a UPS to make sure you don’t trip a breaker.

Ooh, very cool!

Are the two different pictures different wavelengths, or do you just have two seperate sensors? (I have no idea how this works, just a highschool level understanding of x-rays.)

That sounds pretty plausible, but I’m not sure.

The windows are only very slightly off center, inconsistent, and even the ones above the clock are as well (although the clock mechanism could extend both up and down).

But I also don’t have any better explanation.

It isn’t the first time someone built a heavily trapped, walled and patrolled border of that size.

Take a look at the Inner German Border. It was over 1300 km (approx. 810 mi) long, and was (average) about 5.5 km wide (a bit more than 3 miles).

From 1974 to 1979, 4956 people attempted to cross it, and only 229 (4.6%) actually made it.

amateur radio was illegal to encrypt

Amateur radio is still illegal to encrypt (with some exceptions for controlling satelites), because private communication isn’t the point of amateur radio.

Besides, (in most countries) there are some topics that are illegal to talk over amateur radio about, mainly stuff like politics and religion. You’re also not allowed to offer telecommunication services (i.e. pass messages on for others). Enforcing those sorts of laws would be impossible with encryption.

But to answer your question: I think we probably wouldn’t have had an internet. Authoritarian regimes thrive on stability and maintaining the status quo, I think someone high up would have quickly decided that developing that sort of tech is too risky.
