By the end of this book readers should be able to build complex layered applications that visualize multiple data sets, employing different types of visualization, and give end users the ability to interact with and manipulate this data for the purpose of analysis. Style and approach This is a comprehensive guide to the application of QGIS and free/open source software in creating web applications from analysis. Step-by-step blueprints guide the reader through analytical and web development topics and designs.
Getting Started with React
by Manu Singhal Doel Sengupta Danillo CorvalanA light but powerful way to build dynamic real-time applications using ReactJS About This Book * Learn how to develop powerful JavaScript applications using ReactJS * Integrate a React-based app with an external API (Facebook login) while using React components, with the Facebook developer app * Implement the Reactive paradigm to build stateless and asynchronous apps with React Who This Book Is For This book is for any front-end web or mobile-app developer who wants to learn ReactJS. Knowledge of basic JavaScript will give you a good head start with the book. What You Will Learn * Understand the ReactJS basics through an overview * Install and create your first React component * Refactor the ReactJS component using JSX * Integrate your React application with the Facebook login and Graph API, then fetch data from your liked pages in Facebook and display them in a browser * Handle UI elements events with React, respond to users input, and create stateful components * Use some core lifecycle events for integration and find out about ES6 syntaxes in the React world * Understand the FLUX architecture and create an application using FLUX with React * Make a component more reusable with mixins and validation helpers and structure your components properly * Explore techniques to test your ReactJS code * Deploy your code using webpack and Gulp In Detail ReactJS, popularly known as the V (view) of the MVC architecture, was developed by the Facebook and Instagram developers. It follows a unidirectional data flow, virtual DOM, and DOM difference that are generously leveraged in order to increase the performance of the UI. Getting Started with React will help you implement the Reactive paradigm to build stateless and asynchronous apps with React. We will begin with an overview of ReactJS and its evolution over the years, followed by building a simple React component. We will then build the same react component with JSX syntax to demystify its usage. You will see how to configure the Facebook Graph API, get your likes list, and render it using React. Following this, we will break the UI into components and you'll learn how to establish communication between them and respond to users input/events in order to have the UI reflect their state. You'll also get to grips with the ES6 syntaxes. Moving ahead, we will delve into the FLUX and its architecture, which is used to build client-side web applications and complements React's composable view components by utilizing a unidirectional data flow. Towards the end, you'll find out how to make your components reusable, and test and deploy them into a production environment. Finally, we'll briefly touch on other topics such as React on the server side, Redux and some advanced concepts. Style and approach The book follows a step-by-step, practical, tutorial approach with examples that explain the key concepts of ReactJS. Each topic is sequentially explained and contextually placed to give sufficient details of ReactJS.

CentOS High Performance
by Gabriel CanepaCreate high availability clusters to enhance system performance using CentOS 7 About This Book * Master the concepts of high performance and high availability to eliminate performance bottlenecks * Maximize the uptime of services running in a CentOS 7 cluster * A step-by-step guide that will provide knowledge of methods and approaches to optimize the performance of CentOS clusters Who This Book Is For This book is targeted at system administrators: those who want a detailed, step-by-step guide to learn how to set up a high-availability CentOS 7 cluster, and those who are looking for a reference book to help them learn or refresh the necessary skills to ensure their systems and respective resources are utilized optimally. No previous knowledge of high-availability systems is needed, though the reader is expected to have at least some degree of familiarity with any spin-off of the Fedora family of Linux distributions, preferably CentOS. What You Will Learn * Install a CentOS 7 cluster and network infrastructure * Configure firewall, networking, and clustering services and settings * Set up and test a HAC (high-availability cluster) to host an Apache web server and a MariaDB database server * Monitor performance and availability * Identify bottlenecks and troubleshoot issues * Improve performance and ensure high availability In Detail CentOS is the enterprise level Linux OS, which is 100% binary compatible to Red Hat Enterprise Linux (RHEL). It acts as a free alternative to RedHat's commercial Linux offering, with only a change in the branding. A high performance cluster consists in a group of computers that work together as one set parallel, hence minimizing or eliminating the downtime of critical services and enhancing the performance of the application. Starting with the basic principles of clustering, you will learn the necessary steps to install a cluster with two CentOS 7 servers. We will then set up and configure the basic required network infrastructure and clustering services. Further, you will learn how to take a proactive approach to the split-brain issue by configuring the failover and fencing of the cluster as a whole and the quorum of each node individually. Further, we will be setting up HAC and HPC clusters as a web server and a database server. You will also master the art of monitoring performance and availability, identifying bottlenecks, and exploring troubleshooting techniques. At the end of the book, you'll review performance-tuning techniques for the recently installed cluster, test performance using a payload simulation, and learn the necessary skills to ensure that the systems, and the corresponding resources and services, are being utilized to their best capacity. Style and approach An easy-to-follow and step-by-step guide with hands-on instructions to set up real-world simple cluster scenarios that will start you on the path to building more complex applications on your own.
JavaScript JSON Cookbook
by Ray RischpaterIf you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.
