Computer Systems: A Programmer's Perspective

Later on in my career as driver/firmware programmer, Computer Systems - A Programmers Perspective[2] and Unix Systems for Modern Architectures[3] helped a lot to clarify confusions and mysteries.

It's extremely readable and gives you an excellent introduction of machine level code, processor architecture and memory as well as a solid foundation of higher level concepts including networking and concurrency.

Look at the TOC it covers floating point, TMin/Tmax overflow and casting to unsigned problems, gcc use, assembly (enough to understand how exactly pointers work) and many other things including VM/CPUs/Cache memory ect

I very highly recommend that you get and study "Computer Systems: A Programmer's Perspective, 3rd edition" since it is a very practical and detail oriented book(i.e. no hand-waving and full of code for x86-64) for the Programmer.

Computer Systems: A Programmer's Perspective and NAND2Tetris: Elements of Computing Systems are the best books to learn the internals of computer hardware and solidify your understanding of how a computer works.

Computer Systems: A Programmer's Perspective has a lot of good explanations of hardware/os subsystems that can be hard to find detailed explanations of elsewhere.

It's detailed enough to use when trying to understand how a shell works or how to write a signal handler, but the writing couldn't be clearer.

But by the end of it I left with a decent understanding of x86-64 assembly to the point that I could hand compile C functions. And also a rough and ready understanding of how shells, malloc, and web servers work.
