Team Guide to Software Testability
Team Guide to Software Testability
Better software through greater testability
About the Book
Team Guide to Software Testability is the third guidebook in the new collection from Skelton Thatcher Publications.
A practical guide to how testability can help bring teams together to observe, control and understand the systems they build. Enabling them to better meet customer needs, achieve a transparent level of quality and predictability of delivery.
The ‘Team Guide’ collection is designed to help teams building and running software systems to be as effective as possible.
Guides are curated by experienced practitioners and emphasise the need for collaboration and learning, with the team at the centre.
Manuel Pais is an independent DevOps and Delivery Consultant, focused on teams and flow.
With a diverse experience including development, build management, testing and QA, Manuel has helped large organizations in finance, legal, and manufacturing adopt test automation and continuous delivery, as well as understand DevOps from both technical and human perspectives.
Manuel is co-author of the Team Guide to Software Releasability book and lead editor for the remaining books in the Team Guide series.

For both beginning and experienced programmers! From the author of the multi-award-winning Thinking in C++ and Thinking in Java together with a member of the Kotlin language team comes a book that breaks the concepts into small, easy-to-digest "atoms," along with exercises supported by hints and solutions directly inside IntelliJ IDEA!
C++20 is the next big C++ standard after C++11. As C++11 did it, C++20 changes the way we program modern C++. This change is, in particular, due to the big four of C++20: ranges, coroutines, concepts, and modules.
The book is almost daily updated. These incremental updates ease my interaction with the proofreaders.

Java OOP Done RightAlan Mellor
Object Oriented Programming is still a great way to create clean, maintainable code. But only if you use it right.
This book gives you 25 years of OO best practice, ready to use.
You'll learn to design objects behaviour-first, use TDD to help, then confidently apply Design Patterns, SOLID principles and Refactoring to make clean, crafted code.

Ansible is a simple, but powerful, server and configuration management tool. Learn to use Ansible effectively, whether you manage one server—or thousands.
Composing SoftwareEric Elliott
All software design is composition: the act of breaking complex problems down into smaller problems and composing those solutions. Most developers have a limited understanding of compositional techniques. It's time for that to change.
Cloud StrategyGregor Hohpe
“Strategy is the difference between making a wish and making it come true.” A successful migration to the cloud shouldn’t be driven by wishes, but guided by a sound strategy, frameworks, and decision models. This book tells you how—without becoming superficial nor getting lost in technology and product details.
