One of the few books worth your time
Format: Paperback
If you want to learn computers, start here. Learning from a historical perspective removes complexity of trying to start with say GPUs - you learn just like computer engineers did, incrementally.

An absolutely brilliant book
Format: Paperback
This is an amazing book for the right kind of reader. It's a lot like Euclid's Elements but for computers as it leads the reader through designing a computer from first principles and builds to the point of creating software and adding peripherals. It's an amazingly clear but slightly challenging read. I have given this book as a gift many many times. It's an absolute classic in my opinion.

Great introduction to Godot 4
Format: Kindle
I've been writing various types of software for 10 years and was interested in learning Godot for 2D games. This book turned out to be informative and easy to follow and gave me the knowledge I was seeking. I learn best by example, and this project focused book was excellent in that regard.
If you have zero programming experience, I would recommend learning something like Python before diving into this book. The book teaches with GDScript, which is Godot's Python-like programming language.
There are some minor mistakes in the book, but an errata is currently being kept up-to-date on the github repository for the book. I opened a few issues for things I discovered, and the author added those things to the errata. Keep this in mind if you end up getting stuck on something and are 100% sure you followed the directions in the book.
I use Unreal for 3D games, so I have not yet gone through the chapters of this book for 3D games. I wouldn't expect a drastic drop in quality, but for the purposes of this review I can't give any insight on the 3D chapters.
