  • I’d just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.






  • My laptop is called xontros-gatos, which in my native language means fat-cat. Similarly, my server is called server-cat, a small laptop that I have for testing stuff is called small-cat and a new laptop that I just got is called fatter-cat.

  • This is a custom built mini PC, with a mini-ITX motherboard and an Intel N100 CPU. It gets powered by a power supply that I got from an old computer. Also, it needs no active cooling, just a heatsink. It almost never gets above 60°C.

    (and yes, it has no case).

    In it I run:

    • Jellyfin
    • All of the *arr stack
    • Pairdrop
    • My website
    • My personal Lemmy instance
    • Immich
    • Pi-Hole
    • Home Assistant
    • Grafana/Prometheus/Node-Exporter stack for monitoring

  • Oh, I missed the L1 in the title. Basically, all the decryption at L1 is happening inside a Trusted Execution Environment. This is a dedicated chip that does all encryption-decryption (among other things). This is why it is so difficult to extract the keys, because they don’t enter the CPU or are stored in RAM, because the dedicated chip handles all of these.

    So I don’t think you can find a guide about this, because if anyone has found even one exploit, they would be keeping it to ourselves, so that it doesn’t get patched.

    Although it is very difficult, I think the only real solution is to reverse engineer a TEE and find an exploit yourself.

    If you manage to do this, please let me know! I am happy to get updates about progress in this topic.
