Design Patterns and Best Practices in JavaHaving a knowledge of design patterns enables you, as a developer, to improve your code base, promote code reuse, and make the architecture more robust. As languages evolve, new features take time to fully understand before they are adopted en masse. The mission of this book is to ease the adoption of the latest trends and provide good practices for programmers.
We focus on showing you the practical aspects of smarter coding in Java. We'll start off by going over object-oriented (OOP) and functional programming (FP) paradigms, moving on to describe the most frequently used design patterns in their classical format and explain how Java's functional programming features are changing them.
You will learn to enhance implementations by mixing OOP and FP, and finally get to know about the reactive programming model, where FP and OOP are used in conjunction with a view to writing better code. Gradually, the book will show you the latest trends in architecture, moving from MVC to microse ...

Raspberry Pi for Arduino UsersLeverage your Arduino skills in the Raspberry Pi world and see how to cross the two platforms into sophisticated programs.
The Arduino and Raspberry Pi communities overlap more than you might think. Arduinos can be expanded to have network capabilities with a variety of "shields", all of which increase the cost and complexity of the system. By contrast, Raspberry Pis all run Linux, which is a very network-competent platform. The newest Pi, the Raspberry Pi Zero W, is WiFi and Bluetooth capable, and costs around $10 U.S. For network enabled gadgets, it makes far more sense to cross to the Raspberry PI platform, if only someone would make it easy to do. That's what this book is about.
You'll learn some survival level Linux system administration, so you know how to set the machine up and how to establish at least minimal security for your gadget. You'll set up and learn the Geany IDE on your Pi, which is fairly similar to the Arduino IDE.
Where the two platforms overlap the most ...
