For anyone interested in a little more context: the book has a website (including translated versions, etc.) located at https://beginners.re/

It looks like this PDF has been posted to HN a few times before, too: https://news.ycombinator.com/from?site=beginners.re

I haven't read the book, but I did download the PDF and briefly check it out. I'm not a reverse engineer by any means, but this seems like a (very) comprehensive overview. It's over 1000 pages!
