Yeah, I'm a little confused about this "build" of the pdf. It clearly states: "The latest version (and Russian edition) of this text is accessible at beginners.re." - which points to: https://github.com/DennisYurichev/RE-for-beginners

But as far as I can tell there's no branch with a different name - maybe this was just a working title for the English version at some point?

Anyway, this new submission with a new title made take a look, so I'm happy :)

Now, I just hope someone takes a crack at forcing an epub build for better reflow/resize on small screens...

There's a (dormant?) issue: https://github.com/DennisYurichev/RE-for-beginners/issues/37...

The title pages are different. The Reverse Engineering book's title text is hex digits, and is dated July 9, 2018. The Assembly Language book's title page is English text, and is dated today, July 17, 2018. And there is no mention of the Assembly Language book on his home page, yurichev.com.
