Full Review 

Verdict: The main thing to say about this book is that it isn't seven books in one. At best it is four books in one - Python, data processing, AI and physical computing. But the data processing and AI are so slight they wouldn't stand as books in their own right.  The best way to characterise this book is that it covers what you need to know to implement the robot in the final section. Learn Python, AI and some embedded computing and then use it to build a robot is a better description of its contents.

  • Deep C#: Dive Into Modern C# by Mike James


    In Deep C#, I Programmer's Mike James, who has programmed in C# since its launch in 2000, provides a “deep dive” into various topics that are important or central to the language at a level that will suit the majority of C# programmers. Not everything will be new to any given reader, but by exploring the motivation behind key concepts, which is so often ignored in the documentation, the intention is to be thought-provoking and to give developers confidence to exploit C#’s wide range of features.
