"Computer Systems: A Programmer's Perspective" is a great introductory systems textbook on everything going on in a computer.
For more advanced C/C++ developers I can recommend "The Linux Programming Interface" - (https://man7.org/tlpi/). It is a GREAT compendium for writing code against the POSIX API. I have a (legal) copy of this book on all the computers I have access to.
"The Database Redbook" - (http://www.redbook.io) is a valuable source on database implementations.
"Compilers: Principles, Techniques, and Tools" (Dragon Book) is a great starting point. The book is out of print and but I think it should still hold up for most basic use-cases.
