Creating Google Chrome Extensions
Transform your existing web applications into Google Chrome browser extensions and create brand new extensions that improve your own browsing experience and that of your users. This book shows you how Google Chrome browser extensions are extremely useful tools for enhancing the functionality of the Google Chrome web browser. For example, you can create extensions to summarize the current page you are reading, or to save all of the images in the page you are browsing. They have access to almost all of the features provided by the Google Chrome browser, and they can encapsulate such features in the form of a bundled application providing targeted functionality to users. Extensions also run in a sandboxed environment, making them secure – which is a huge plus in the modern web! The APIs provided by the Chrome Extensions framework help you empower web applications by coupling them with amazing features provided by the Google Chrome web browser, such as bookmarks, history, tabs, action ...

Building a Virtual Assistant for Raspberry Pi
Build a voice-controlled virtual assistant using speech-to-text engines, text-to-speech engines, and conversation modules. This book shows you how to program the virtual assistant to gather data from the internet (weather data, data from Wikipedia, data mining); play music; and take notes. Each chapter covers building a mini project/module to make the virtual assistant better. You'll develop the software on Linux or OS X before transferring it to your Raspberry Pi, ready for deploying in your own home-automation or Internet of Things applications. Building a Virtual Assistant for Raspberry Pi walks you through various STTs and TTSs and the implementation of these components with the help of Python.

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 ...
