Raspberry Pi IoT Projects
This book is designed for entry-through-intermediate-level device designers who want to build their own Internet of Things (IoT) projects for prototyping and proof-of-concept purposes. Expert makers may also find interesting new approaches. Raspberry Pi IoT Projects contains the tools needed to build a prototype of your design, sense the environment, communicate with the Internet (over the Internet and Machine to Machine communications) and display the results. Several IoT projects and designs are shown from the start to the finish including an IoT Heartbeat Monitor, an IoT Swarm, IoT Solar Powered Weather Station, an IoT iBeacon Application and a RFID (Radio Frequency Identification) IoT Inventory Tracking System. The software is presented as reusable libraries, primarily in Python and C with full source code available. Raspberry Pi IoT Projects: Prototyping Experiments for Makers is also a valuable learning resource for classrooms and learning labs. ...

Relational Database Programming
Learn the best way of writing code to run inside a relational database. This book shows how a holistic and set-oriented approach to database programming can far exceed the performance of the row-by-row model that is too often used by developers who haven't been shown a better way. Two styles of programming are encountered in the database world. Classical programming as taught in many universities leads to an atomic, row-oriented, and procedural style inspired by the structured models of programming. In short, many application developers write in the relational database exactly like in the user interface. The other style of programming is holistic, data set oriented, and coded mainly in SQL. This is the style of the database developer. The set based and holistic style of development is not promoted enough in universities, and many application developers are not fully aware of it. There are many performance issues all over the world in relational databases due to the use of the ato ...

RESTful Web Clients
Web-based REST and Hypermedia services are becoming more common every day, but very few client libraries take advantage of these powerful API features—mostly because the techniques and patterns needed to create successful hypermedia clients have been ignored. Yet, when done right, hypermedia-based client applications exhibit more stability and flexibility than typical one-off custom client code. This practical book takes you on a journey from custom bespoke implementations to powerful general-purpose client applications and, along the way, shows how you can harness many of the basic principles that underpin the Web. Throughout the book, you'll find practical, approachable examples and dialogs, as well as clear guidance on how to understand this increasingly important conversation. ...

RSpec Essentials
This book will teach you how to use RSpec to write high-value tests for real-world code. We start with the key concepts of the unit and testability, followed by hands-on exploration of key features. From the beginning, we learn how to integrate tests into the overall development process to help create high-quality code, avoiding the dangers of testing for its own sake. We build up sample applications and their corresponding tests step by step, from simple beginnings to more sophisticated versions that include databases and external web services. We devote three chapters to web applications with rich JavaScript user interfaces, building one from the ground up using behavior-driven development (BDD) and test-driven development (TDD). The code examples are detailed enough to be realistic while simple enough to be easily understood. Testing concepts, development methodologies, and engineering tradeoffs are discussed in detail as they arise. This approach is designed to foster the rea ...
