  • Just high school.
    I didn’t manage to keep a good score during the first year, so I got kicked out, and I have to wait a year to get back as I have to go through admissions same way as a brand new student (and also none of my passed subjects will count except for English…).
    That was computer science.

    As for what I’d be interested to learn and get into, and why:

    • German (better job opportunities)
    • Ukrainian (I struggled with communication on a dorm as most students living there were from Ukraine)
    • Linux Kernel development (Mostly due to interest in mobile Linux.)
    • Software reverse-engineering (Could help with above, static malware analysis, and just overall curiosity.)
    • Assembly - RISC-V, ARM, AMD64 (The above 2 points, as well as having more control over what software does.)
    • C++ (Making my own GUI programs utilizing Qt. I’d also like to modify cdimage to generate shorter tracks, improve the UI and integrate it into K3b. I think it should be possible to put it into pregap on audio CDs (K3b already has support for that bit), as well as combine it with data in “Mixed mode” CD.)
    • Digital signal processing (Due to my interest in SDRs.)
    • RF circuit and antenna design (For UHF and above.)
    • Mobile telecommunications (sharetechnote.com has some interesting info, and I’d like to understand it and know more)
    • QEMU (I’d like to at least partially replace my reliance on VirtualBox and be less stupid around Proxmox)
    • Management of *BSD and Solaris (NetBSD, FreeBSD, OpenIndiana, Oracle Solaris)
    • Networking (We did CCNA in high school, but it got boring, especially with no purpose aside from national competitions I attended thrice. I need to revisit CCNA-level info and move up higher.)

    I don’t think that’s a complete list, just what’s on my mind.










  • Mate, even you just understanding what LaTeX and HTML do

    With HTML, I only meant something like basic 90s/early 2000s websites. That doesn’t really need much. For example, toastytech.com. Using tables for layout is probably not done anymore.
    When it comes to LaTeX, we just had to use it for an assignment in school, so that’s where I came in contact with it.
    And even that’s something I struggled with. The entire page was supposed to be a colored table. I’ve used tabularx, but it kept being slightly off the page. For some reason, wrapping it between center fixed it, but I don’t know what I did wrong there.

    It would have probably been easier if I did it in Overleaf (online LaTeX editing platform).
    Instead, me being me, I was doing it last-minute. On a train. Full train, so I couldn’t even sit down to use a laptop, as such I had to use my phone. There are apparently some issues with texlive on Termux, so I didn’t run it locally.
    Instead I had to SSH to my mini PC over Tailscale, edit the document using Vim, compile with pdflatex, copy the PDF to my phone using scp, view it, delete, browse around StackExchange (where I found someone mention the center workaround), and repeat.

    On a phone, while standing in a moving train. Quite the user experience.





  • Environment is basically any. I used to read on my touchscreen 2-in-1 ThinkPad using Arianna from KDE.

    But I stopped because of software annoyances.
    At some point, native Arianna package broke on Arch. It’s fixed now, but the UI has changed. In the past, while in portrait mode it also shown 2 columns, just slimmer ones (I think that’s version 24, I am not currently on that laptop). Now it only shows 1 page in the middle of the screen.
    I also have an old Flatpak version installed which still has the older UI (I believe the older native package didn’t work with current dependencies), but simply the knowledge of that thing taking up in total 4GiB (as it’s the only Flatpak I have) while the native version is 1.6MiB bothers me enough not to use it.
