With this concise book, you will quickly gain working knowledge of Sinatra and its minimalist approach to building both standalone and modular web applications. Sinatra serves as a lightweight wrapper around Rack middleware, with syntax that maps closely to functions exposed by HTTP verbs, which makes it ideal for web services and APIs. If you have experience building applications with Ruby, you’ll quickly learn language fundamentals and see under-the-hood techniques, with the help of several practical examples. Then you’ll get hands-on experience with Sinatra by building your own blog engine. Learn Sinatra’s core concepts, and get started by building a simple application Create views, manage sessions, and work with Sinatra route definitions Become familiar with the language’s internals, and take a closer look at Rack Use different subclass methods for building flexible and robust architectures Put Sinatra to work: build a blog that takes advantage of service hooks provided by the GitHub API

    He was a celebrity during the height of America’s Gilded Age. In this book, you will read about his friendship with Mark Twain, his furious competition with his former employer Thomas Edison, his uneasy relationship with billionaire J.P. Morgan, and his rivalry with Albert Einstein. During his lifetime, Tesla revolutionized the field of electrical engineering with his most famous invention: the induction motor. But that wasn’t all he contributed to the world of technology. His coils, turbines, robotic boats, and mysterious “death ray” continue to beguile the imagination and inspire the inventors of the 21st century. But who was Tesla really? This book will take you from his early childhood in Croatia, where he experienced strange optical visions and “luminous phenomenon” that gave him near super-human powers of memory and visualization, to the “War of the Currents”, Thomas Edison’s bizarre campaign to ruin Tesla’s reputation. From trying to fight the Spanish American War with robots, to electrifying the skies of the Colorado desert, and to starting an earthquake in the middle of New York city, learn how Nikola Tesla shaped the world we live in today.

The course is available in English on the nonprofit open source edX.org platform, and in Arabic on edraak.org. Over 100,000 students have already registered for these MOOCs.

    Experienced birders use the most easily observed characteristics — size, structure, behavior, and general color patterns — to identify birds even before looking carefully at plumage details. Now birders at all levels can learn how to identify shorebirds quickly and simply. This guide includes more than 870 stunning color photographs, starting with a general impression of the species and progressing to more detailed images of the bird throughout its life cycle. Quiz questions in the captions will engage and challenge all birders and help them benefit from this simplified, commonsense approach to identification.

     I believe that everyone who needs (and wants) a Service Dog should be able to have one, so I'm retiring from my Service Dog Training Coach business to focus on consolidating my lifetime of training experience into books (as well as dedicating time to answer questions for my readers, on the phone or via Skype as well as on the Facebook Group (facebook.com/groups/180613442286351/) all of which will be available for as long as my health permits, in case you have a training question that the book didn’t answer). If you are training your own Service Dog, this book will help guide you through the process. It starts with the basics, creating a firm foundation to build upon for any type of Service Dog that you may be training. When you finish the 30 Day Intensive Training Program included in this book, your dog will have several foundation behaviors that he'll need to do his Work as a Service Dog, as well as one Task that can be customized to the individual for a number of types of disabilities. Your dog will learn to have good manners in public, and also to conduct himself in a way that will allow him to keep his attention on his Service Dog Work. I'll show you how to teach your dog to help you deal with your life challenges, and with this method of training, he will “learn how to learn," which will make your job of continuing his training even easier! This is the Facebook group that I mentor in order to provide additional support for readers of my books: Please join us there! :) facebook.com/groups/180613442286351/

    But what should we change and how do we do it? Annabel Streets and Susan Saunders spent their 30s climbing the career ladder, having children and caring for elderly parents - all at the same time. By their 40s, they were exhausted, stressed, sleeping too little and rushing too much. They began to ask whether the prolonged ill health and dementia suffered by their parents was their inevitable future too - could they do anything to avoid requiring their own children to care for them in old age? Thus began THE AGE-WELL PROJECT.
