You can now easily extend the framework, change its behavior, and replace whole components to bend it to your will, all without messy hacks. This pioneering book is the first resource that deep dives into the new Rails 3 APIs and shows you how use them to write better web applications and make your day-to-day work with Rails more productive. Rails Core developer Jose Valim guides you through seven different tutorials, each of them using test-driven development to build a new Rails extension or application that solves common problems with these new APIs. You will understand how the Rails rendering stack works and customize it to read templates from the database while you learn how to mimic Active Record behavior, like validations, in any other object. You will find out how to write faster, leaner controllers, and you'll learn how to mix Sinatra applications into your Rails apps, so you can choose the most appropriate tool for the job. In addition, you will improve your productivity by customizing generators and responders. This book will help you understand Rails 3's inner workings, including generators, template handlers, internationalization, routing, and responders. With the knowledge you'll gain, you'll be ready to tackle complicated projects more easily than ever before, creating solutions that are well-tested, modular, and easy to maintain.

    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

     I mean, it took more than a year before anybody looked up from their smartphones long enough to wonder why so many of their neighbors were infected. Why so many were dying. The vaccination riots came and went. The grocery store shelves emptied out. The spigots eventually ran dry. That was around the time I moved underground and sealed the hatch on my backyard bunker. That was a couple of years ago. Now, my radio hasn't picked up a signal from the world up top since I can't remember when. My exterior camera died in a storm last spring. And the loneliness has set in, gnawing at me, making me think crazy thoughts, including the one that'll change everything. I have to leave the bunker and see if anyone is left alive.

     Whoever created him used the following recipe: Dreamy eyes, playful smile, and rock-hard muscles that give you chills. Add a pinch of humor, coupled with quick-witted intelligence and a mysterious aura that will make you feel slightly insecure. When I met him on a winter climbing excursion, I didn’t expect to wake up in his tent the next morning. It may be minus ten degrees outside, but he makes me melt. I believe I’ve just met the father of my future children... But the more I want to know about him, the more questions I find. Why does he live completely alone in a villa in the mountains? Why does he never talk about his past? And where does the sadness in his eyes, which flashes every now and then, come from? Fate ensures that I get answers I would never have expected. Even worse, when a devastating fire breaks out in the mountains, Cole has to leave his shelter - and suddenly his face can be seen on every TV channel in the country. What the hell is going on here? And who is this man I love? "My next Mistake" is a full-length standalone romance with no cheating and no cliffhangers, but with a gorgeous protective alpha male, plenty of steam and a guaranteed HEA. I've also included a preview of my romance novel "Unexpected Surprise" for you. Happy reading! - Sarah J. Brooks (USA Today Bestselling Author)
