I'm second-career web developer (writing mostly Ruby) since 2022, meaning I didn't get a computer science degree. So this list is me catching up.
My "Learn Ruby" list slightly overlaps with the material in this list, namely the section "Foundations" and some of the section"Beyond Ruby web development", which include resources that are more engineering-related than what's in this list.
