Linux is really a superfamily of loosely-related OS’s (called distributions). Arch and Debian are 2 of the more common ones. Arch in particular has a reputation of being really beginner un-friendly, particularly in that, to my understanding, you have to build the OS yourself.

There’s also the caveat that many Linux distributions end up sharing/copying code from each other, so you end up with a kind of “OS lineage.” The most common distribution, Ubuntu, is copied from Debian. And then the most beginner-friendly distribution, Linux Mint, is copied from Ubuntu. Arch, to my knowledge, doesn’t copy code from elsewhere, so much of the advice given from users of other distributions won’t apply to Arch (hence the meme, “I use Arch btw”)

Anyways, the real advice for a Linux beginner is to stick with a beginner-friendly distribution: either Ubuntu or Linux Mint or Pop!_OS. Most or all distributions have various “flavors,” which are basically like how the OS looks. I think the real difficulty is picking a flavor that you like. I personally like the look of KDE Plasma (IMO resembles Windows 10 the most), so my personal recommendation is Kubuntu, which is the KDE Plasma flavor of Ubuntu

There is also the factor that the user appears unaware that the feature he is requesting is already present, because you can just cut/paste.

You’re correct. Modern keyboards have the CPU poll the keyboard rather than interrupting the CPU. Hardware interrupt really occurred with the old PS/2 keyboards, so this meme is technically outdated

Oh, just because someone is abusive or unsupportive doesn’t mean that they don’t love you. It just means that their interactions aren’t healthy for you and you need to establish boundaries.

Regardless, I hope that you’re doing well. I don’t know what your project is, but I can certainly tell you that it’s much more impressive than anything I’ve made
