CS50 (https://www.edx.org/course/cs50s-introduction-computer-scien...) - Best Intro to Computer Science
Nand2Tetris I and II (https://www.coursera.org/learn/build-a-computer) - Build a computer from logic gates up to a compiler, this is the best class I've ever taken.
Agile Development Using Ruby on Rails (https://www.edx.org/professional-certificate/agile-developme...) - Great introduction to web development and software engineering principles
I've also been reading some technical books. Would definitely recommend
Modern Operating Systems - Tanenbaum Designing Data-Intensive Applications - Kleppmann
