Ask HN: Are there any books or online courses that changed the way you program?

I am currently going through the course CS61B from UC Berkeley. The videos and assignments are open for the public. I am doing the Spring 2025 one. I haven't had a formal CS education.

The quality of the course blows my mind. I am fascinated. I want to learn more about CS and programming. I want to become a better engineer.

Which courses or books or topics should I study thoroughly? Can you provide links to the resources if possible?
