To pick on graphics, since I'm more familiar with that domain, the problem isn't that this tutorial is about software rasterization, it's that the tutorial is a raytracer that doesn't do shading, textures, shadows, or any geometry but spheres, and spends most of its word count talking about implementing the trig functions on fixed-point numbers instead of just using math.h functions on IEEE floats.

Well put! This succinctly sums up the crux of my argument in my other comments.
