    Here’s one I have saved in my shell aliases.

    nscript() {
    local name="${1:-nscript-$(printf '%s' $(echo "$RANDOM" | md5sum) | cut -c 1-10)}"
    echo -e "#!/usr/bin/env bash\n#set -Eeuxo pipefail\nset -e" > ./"$name".sh && chmod +x ./"$name".sh && hx ./"$name".sh
}
alias nsh='nscript'

    Admittedly much more complicated than necessary, but it’s pretty full featured. first line constructs a filename for the new script from a generated 10 character random hash and prepends “nscript” and a user provided name.

    The second line writes out the shebang and a few oft used bash flags, makes the file executable and opens in in my editor (Helix in my case).

    The third line is just a shortened alias for the function.

    How does the xz incident impacts the average user ?

    It doesn’t.

    Average person:

    • not running Debian sid, Fedora nightly, Arch, OpenSUSE Tumbleweed, or tbh any flavour of Linux. (Arch reportedly unafffected)
    • ssh service not exposed publicly

    The malicious code was discovered within a day or two a month of upload iirc and presumably very few people were affected by this. There’s more to it but it’s technical and not directly relevant to your question.

    For the average person it has no practical impact. For those involved with or interested in software supply chain security, it’s a big deal.

    Edit:
    Corrections:

    • OpenSUSE Tumbleweed was affected; Arch received malicious package but due to how it is implemented did not result in compromised SSH service.
    • Affected package was out in the wild for about a month, suggesting many more affected systems before malicious package was discovered and rolled back.

    Since you’re in EU you have quite a few options for vendors. Here is a good list.
    I looked through most of these vendors before and it’s unlikely that you’ll find everything you need to build a fully custom keyboard from a single vendor, but with 2 or more you should be able to source all the pieces you need.
    Some vendors that have a decent selection:

    Another option of you don’t mind the potentially long shipping time is to buy all the components from Aliexpress. They will likely have an expansive selection and lower price compared with EU retailers, but you may or may not end up paying tax, and the shipping time will be longer on everything.

    I managed to figure out an ugly way of getting the keyboard matrix down to 20 pins, but a much better option to using a pro-micro would be to go with an Elite-Pi or Helios Microcontroller Since it has 23 GPIO pins, and there won’t be a hacky workaround like with the pro-micro.

    One thing I forgot to mention is key switch preference, the two main types are MX (high profile) and Choc (low profile). MX switches are both easier to find and have much larger variety of both switches and keycaps. Choc is nice because it has a lower profile similar to laptop keyboards, but the selection of switches and keycaps are much more limited. There are other low profile switch types like Choc mini (PG1232), Choc V2(PG1353), and Notebook X(PG1425) switches, but they’re even harder to source than the Choc V1(PG1350).

    We could also make it so pressig the two shift buttons simultaneously is how you lock into upper-case letters.

    I haven’t tried it before but I’m almost certain it’s possible to do with QMK or ZMK firmwares.

    As for the lack of pins generally, the easiest thing to do would be to use a microcontroller with more pins, but that may bring more challenges when designing the pcb depending on the availability of good component footprints.

    The most commonly used footprint is for the pro-micro though, but you’d end up needing to cut 4 rows/columns off of the board to fit within its pin constraints, though I do think there is a modification for pro-micros that can give you two more pins, which could technically work if you cut off the rightmost column and the function row.

    If you’re willing to get rid of just the rightmost row you would be able to use something like the nice!nano since it has 21 gpio pins. It would become optionally wireless in that case as well.

    If you didn’t want to cut down the board at all, could also go with something like an Elite Pi, which has a similar footprint to the pro-micro except with an extra 5 pins along the bottom edge, as it has the same footprint as the elite-c.

    Quite a few options, and I’m not sure if you have a preference for wired vs. wireless or parts availability where you are, so those would likely influence what you decide to go with.
