Ansible Playbook Essentials
Ansible combines configuration management, orchestration, and parallel command execution into a single tool. Its batteries-included approach and built-in module library makes it easy to integrate it with cloud platforms, databases, and notification services without requiring additional plugins. Playbooks in Ansible define the policies your systems under management enforce. They facilitate effective configuration management rather than running ad hoc scripts to deploy complex applications. This book will show you how to write a blueprint of your infrastructure encompassing multi-tier applications using Ansible's playbooks. Beginning with the basic concepts such as plays, tasks, handlers, inventory, and the YAML syntax that Ansible uses, you will see how to organize your code into a modular structure. Building on this, you will master techniques to create data-driven playbooks with variables, templates, logical constructs, and encrypted data. This book will also take you through advan ...

3D Printing Designs: Design an SD Card Holder
Want to model a 3D printed prototype of an object that needs to be replaced or broken? This book will teach you how to accurately measure objects in the real world with a few basic measuring techniques and how to create an object for 3D printing around the objects measured. In this book, you'll learn to identify basic shapes from a given object, use Vernier and Digital calipers and grid paper tracing techniques to derive measurements for the objects. With the help of measurements, you'll see to model these objects using Blender, organize the parts into layers, and later combine them to create the desired object, which in this book is a 3D printable SD card holder ring that fits your finger. ...

Material Design implementation with AngularJS
Building web and mobile apps that are interactive, fluid and provide consistent experience across devices ranging from desktops, tablets and smart phones is challenging. User Interface (UI) elements need to adapt to various screen sizes and yet the code behind need to be reusable and follow best of coding practices. Material Design with AngularJS details out building such sophisticated web and mobile apps by combining Material Design and AngularJS concepts. Material design takes mobile-first approach. User Interactions are built to be natural with animations, positioning of elements and more. AngularJS provides many web development features like routing, accessibility, localization etc. out of box. And the framework's implementation of design patters like Dependency Injection, Model View Controller or Model View-View Model will allow better separation of concerns. This book dwells into following libraries, i) Angular Material- being built by Google team for getting best of ...

Rails 5 Test Prescriptions
Your Ruby on Rails application is sick. Deadlines are looming, but every time you make the slightest change to the code, something else breaks. Nobody remembers what that tricky piece of code was supposed to do, and nobody can tell what it actually does. Plus, it has bugs. You need test-driven development: a process for improving the design, maintainability, and long-term viability of software. With both practical code examples and discussion of why testing works, this book starts with the most basic features delivered as part of core Ruby on Rails. Once you've integrated those features into your coding practice, work with popular third-party testing tools such as RSpec, Jasmine, Cucumber, and factory_bot. Test the component parts of a Rails application, including the back-end model logic and the front-end display logic. With Rails examples, use testing to enable your code to respond better to future change. Plus, see how to handle real-world testing situations. This new edition ...
