And of course, there's Eldad's venerable old book : https://en.wikipedia.org/wiki/Reversing:_Secrets_of_Reverse_Engineering

And then, there's xorpd - who also appears to be Israeli : https://www.xorpd.net/pages/x86_adventures.html ("You must do the exercises. You may say, 'I'm a fast learner and I can learn a lot by watching your lectures.' To this I would say, would you attempt to learn swimming by just watching lectures?"
