Operating Systems: Three Easy Pieces is a book for those interested in learning the fundamental conceptual underpinnings of modern operating systems. Centered around three main concepts - virtualization, concurrency, and persistence - the book covers a wide range of topics needed to understand how modern operating systems function.
Very costly
This is a great book and unlike other operating systems books like the dinosaur book, it feels practical. There are tips and suggestions on tools that are very interesting and would help in exploring your installed OS better.
There are code examples too of high quality.
Since the book is already free, I think printing out PDFs would be cheaper than the book itself and moreover the content will have updates too!
