Go through the theory in the thesis with pen and paper, use the references as needed. Thesis, article on it by Shannon and lots of commentary available freely online. He provided a number of practical applications, with breakdown.
Here is the core question you need to answer to understand logic in computers: what can you do with just yes and no, represented as 1 and 0?
Why were these numbers reversed in Shannon's thesis?
In his thesis, 1+1=1. Why? If you understand postulates, it makes sense for the kind of theory he is developing. If not, you should be very excited: mathematical theory, unlike how it is presented in bad schools, is not about following rules someone has decided on. It is about making sense in accordance with the logic you decide upon! This is as close as you can get to real magic, magic you can prove and make manifest in reality. Contemplate this deeply.
What kind of information can you transmit with a lamp and a switch, turning the lamp on and off? (Tip: this is the whole idea behind how the super-modern fiber-optic cables are transmitting information today, with lights blinking on and off, real fast, from one end to the other. Poetically, they are the core of the Internet).
Following the hyperlinks and looking up what you need should provide all the information required and more.
I'm sure it also depends on the topic; I only tried the free graphs course.
The math and science subjects I'd say is most mature, and has the most content. thereafter one can practice more from textbooks or alike to really go into the depth and expand on the mastery.
Logic can be described in a book, but I don't think it can be taught in a book. It's a consequence of solving a lot of problems over a long period of time. My suggestion would be to pick up any book/website with programming problems and work on them every day changing the problems every so often, however nothing beats actual work experience where you have someone to explain to you why something is a good approach and why not. Understand what is expected of you, see how it fits in the big picture and start by breaking it down into smaller pieces. It's very simple, just getting it takes time.
