I started reading "RabbitMQ in Action" having already used it in production. That said, I was still a bit unclear about some aspects of messaging in general: AMPQ and RabbitMQ, specifically. My previous experience included deploying RabbitMQ on AWS and using it to offload the job of sending many e-mails from my main application. For that I used django-celery.
“Erlang and OTP in Action” is not a repeat of the existing introductory books on the Erlang language, although there is a brief introduction to the language in Chapter 2. This book continues where other books leave off. If you are just learning Erlang, this book is probably not the best place to start, however it is an excellent reference for more advanced topics
Vernon Cedar, the author of The Quick Python Book, First Edition, has written a well rounded introduction and reference manual to the Python scripting language. My previous experience with coding was writing C at Nortel in the 90's. I hadn't done much coding since, but I always had the bug to get back into it. My friend suggested that I read and review this book as my introduction to Python.
The Quick Python Book is a good and short introduction/overview of Python 3. The book covers a lot of ground,
but because it is relatively slim (about 300 pages or so) it is no wonder that in many places the author instructs
the reader to look for more information from online sources. Additionally some more challenging topics (like decorators)
are not explained in enough detail, which leaves the reader wondering if those part should have been left out of the book
completely (or explained better).
