Bottom up cs is a great resource. https://www.bottomupcs.com/ It might feel very low level at first but once you understand these fundamental building blocks of computers you will be really well equipped to build upon this knowledge and learn higher level concepts. I also think the Rust Programming book (https://doc.rust-lang.org/book/) is a great resource for general programming knowledge. Some sections e.g. on the borrow checker and lifetimes aren’t 100% applicable to general programming knowledge but I still recommend it. It is more of a 201 level book instead of 101 though.

That website is poorly named. It's not about computer science any more than a resource on anatomy is about medicine.
