I like the chromatic aberration links on your page. It's an eye burner and not functional, but I like it.
Good to know!
It's fine that the first two guides are all theory, though! Most beginners guides dive right into code too quickly. With your two guides, I felt confident enough to play around with some existing shaders, and non-randomly change stuff around, and even combine them!
I do agree, the reason I am going with this route is that, with the third and fourth saying "this is how you make a custom shader to your framework", requires that you unpack the examples and decide what is superfluous, what is intentional, what is critical etc is directly descended from knowing where values get plugged in and why.
In other words, the other articles will make no sense without this post, but I am using it as a pre for 3 and 4, and getting input/feedback on the topics that people are most desiring to understand when entering the land of shaders for the first time.
So do suggest stuff, I can always do non-series related shorter posts on tangents etc.
