A book from this person would be amazing!

But I really dislike these markdown books used by many rust projects. I wish they just had an option to download it as a PDF, so that I could archive them. The printing button really isn't good enough for that. I mean if everything is already neatly renderd to HTML like that, how hard could it realistically be to also create a good looking PDF version...
But these subjects evolve so fast, that having a bunch of .deadtrees lying around just become a nuisance.
If all I want is some form of archive to look back on later, a bunch of .md files seems perfect.
.... is what I was going to say until I went and hit the print button and 10% of the text was missing and everything was right aligned in the top right corner.
Yikes. You may find it worthwhile to clone the repo, iterate over it with pandoc to make A Big HTML File and then use your browsers print feature or pandocs converter. That's about as good as you'll get without a lot of pain ime.
Tbh, would probably still recommend rendering it with pandoc because the h1's being split that way does annoy me, but at least it gets the content right.
If you already have the knowledge to understand the notes in the slides, it's probably pointless to you. If you don't, the slides make no sense at all since nothings explained.
What am I missing here that's so great ?
The repository contains the materials of a class, so without attending the class or having a rather strong pre-existing knowledge about hypervisors on x86-x64, the material is going to be very hard to follow.
From my PoV, there are definitely better (as in, explained with a lot more details) tutorials online on how to start your hypervisor from scratch which I'd recommend before trying to understand this one (which has some really nice peculiarities such as Fuzzing UEFI with code coverage).
