  • There’s a place in northern Australia where I’ve watched this happen (and, as a tourist there, I’ve been part of the problem of course).

    It’s a river with warm (something like 30 °C, I don’t know the exact temperature) water and a little bend, so you get in one side, float around the bend, and then walk back to the start.

    It has some facilities built nearby, a toilet, and a campground in walking distance, so its not “secret” or “hidden”. Its just off the Stuart Highway too, so not really remote. I think it was just unknown to most people for a while.

    I was there once in 2019, and again in 2024. Nothing major had changed, but it was starting to get a bit crowded, the campground had grown, and much of the plants in/around some parts of the river where broken.

    I was initially gonna write this without naming the place, but after thinking about it, what little attention it might get from the few people here won’t really change what’s happening to it, so I looked it up again: Bitter Springs, near Mataranka, but its not the Mataranka Thermal Springs, those are something different. Apparently, its also part of a national park.





  • This is only partially true.

    RSA public keys consist of two parts:

    1. The exponent e, which is usually 65537, for the reasons you described.
    2. The modulus n, the product of the two primes used for generating an RSA keypair.

    If the public key were always completely the same, then there would be no point in making different private keys.


  • I think there are three main issues (though I might be overlooking something):

    1. AI taking over peoples work is as much an issue for mathematicians here, as it is for programers, artists, writers, etc. elsewhere.
    2. We still need to check if these 700 papers are correct (AI makes mistakes at least as often as humans, usually more often). This involves a huge amount of effort. And if it turns out that they contain a bunch of mistakes, OpenAI is unlikely to care. To them, these papers have already served their purpose (generating headlines).
    3. Solving a problem in mathematics means being able to (formally) convince other people that your opinion is correct (massively simplified, but imo that is what mathematics boils down to), by getting them to understand why your opinion is correct. Having a pile of linear algebra spit out 700 texts about certain math problems removes the whole “human understanding” part of that.

    However, it’s not entirely unprecedented for a computer to provide a proof that we don’t completely understand. I forgot the details (and I’ll edit them in if I can find it), but there was at least one problem that was solved using a computer and brute force trying millions of cases. That produces a proof much longer than any human could read in a lifetime, and iirc there where quite a few mathematicians unhappy about it at the time too.




  • Debian is the OS.

    Proxmox builds on Debian to turn it into a hypervisor. That’s an OS for managing VMs and containers. Proxmox (like most hypervisors) gives you a handy webinterface.

    There are easier hypervisors to use, but Proxmox is great for learning, and allows you to expand well later.

    tbh, except for gaming and AI, you don’t need nearly as much processing power as you might think. I run most of my stuff on a (fairly new, can’t remember which one exactly) i5, and it sits at an average 2-3% CPU usage, with the maximum its recorded being 10.9% (there’s two VMs and 8 containers running on it). 11th gen i5 will probably be more than enough to start with.

    In my non-professional opinion, what you really want to look at is how much power your system is going to use when idle, since that’s what (small) servers are doing most of the time. This is not something specified by manufacturers, and it depends on all the parts going into the computer (CPU, mainboard, PSU, fans, how the BIOS is set up, …).

    I would also recommend getting at least 16 GB of RAM (honestly I would say 32, if not for the current prices). Containers don’t use too much, but if you want to set up VMs for services, each VM will want at least 2-4 GB for itself.

    LXC-Containers (https://en.wikipedia.org/wiki/LXC) are like extremely lightweight and slightly less secure Linux VMs. They are similar to Docker, but while Docker is containerizing applications, LXC containerizes Linux distros.



  • 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.

    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



  • 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.
