Hi im Cora! :D
to a new person, those tutorials and manuals are the “random code and unknown commands” that i spoke about in the above comment. i thought i made that very clear. nothing is known until it is learned, and things cannot be learned without practice. practice leads to initial failure, and the frustrations with that are what the linux challenge was about.
the problem with a lot of these recommendations though is that to a non-linux user: all code is random, and no commands are understood. you only learn by doing, and if you cant do until you know, you’ll never get anywhere. you gotta make a few mistakes to learn anything, and thats what happened. yea he paid the stupid tax, but so does everyone else while they learn a new thing. that was the entire point of the challenge: how hard is it? and it turns out, quite! info is scattered, theres lots of commands and code that sounds like it’ll do what you want but is actually a bad idea (as evidenced by the recommendations you point out), and things can break easily. thats the video.
something people havent mentioned yet but that i ran into as a problem: qmk doesnt support per-key lighting in the sense that you cant have specific colours for each key. it supports per-key lighting in the sense that you can do effects, but you cant set the alphas to be a different colour from the ergo keys, for instance.
