Elixir Cookbook
This book is a set of recipes grouped by topic that acts as a good reference to get ideas from or to quickly search for a solution to a problem. You will begin by launching an IEx session and using it to test some ideas. Next, you will perform various operations like loading and compiling modules, inspecting your system, generating a supervised app, and so on. Furthermore, you will be introduced to immutability, working with data structures, performing pattern matching, and using stream modules to generate infinite data sequences. You will learn about everything from joining strings to determining the word frequency in text. With respect to modules and functions, you will also discover how to load code from other modules and use guards and pattern matching in functions. ...

Understanding Context
To make sense of the world, we're always trying to place things in context, whether our environment is physical, cultural, or something else altogether. Now that we live among digital, always-networked products, apps, and places, context is more complicated than ever-starting with "where" and "who" we are. This practical, insightful book provides a powerful toolset to help information architects, UX professionals, and web and app designers understand and solve the many challenges of contextual ambiguity in the products and services they create. You'll discover not only how to design for a given context, but also how design participates in making context. ...

Arduino Android Blueprints
Arduino is an open source microcontroller built on a single-circuit board that is capable of receiving sensory input from the environment and controlling interactive physical objects. The first few projects of this book will focus on displaying tweets within your app by connecting to Twitter, controlling basic functions of the Arduino board, and connecting an Arduino-powered weather station to an Android phone via Bluetooth. Next, you will learn how to use the Arduino Yún board to connect a standard USB camera to a local Wi-Fi network. At the end of the book, you will build a simple mobile robot, connect it to an Arduino board and a Bluetooth module, then control the robot from an Android phone using Bluetooth. Each project is explained in a step-by-step fashion, always starting with the choice of components and the assembly of the hardware. ...

Learning Internet of Things
This book starts by exploring the popular HTTP, UPnP, CoAP, MQTT, and XMPP protocols. You will learn how protocols and patterns can put limitations on network topology and how they affect the direction of communication and the use of firewalls. Thing registries and delegation of trust are introduced as important tools to secure the life cycle of Things on the Internet. Once the fundamentals have been mastered, your focus will move to the Internet of Things architecture. A secure architecture is proposed that will take full advantage of the power of Internet of Things and at the same time protect end user integrity and private personal data without losing flexibility and interoperability. This book provides you with a practical overview of the existing protocols, communication patterns, architectures, and security issues important to Internet of Things. ...
