Flux Architecture. Design and Build Modern JavaScript Web Applications

Adam Boduch

Whilst React has become Facebook’s poster-child for clean, complex, and modern web development, it has quietly been underpinned by its simplicity. It’s just a view. The real beauty in React is actually the architectural pattern that handles data in and out of React applications: Flux. With Flux, you’re able to build data-rich applications that engage your users, and scale to meet every demand. It is a key part of the Facebook technology stack that serves billions of users every day.This book will start by introducing the Flux pattern and help you get an understanding of what it is and how it works. After this, we’ll build real-world React applications that highlight the power and simplicity of Flux in action. Finally, we look at the landscape of Flux and explore the Alt and Redux libraries that make React and Flux developments easier.Filled with fully-worked examples and code-first explanations, by the end of the book, you'll not only have a rock solid understanding of the architecture, but will be ready to implement Flux architecture in anger.

FreeRADIUS Beginner's Guide. Master authentication, authorization, and accessing your network resources using FreeRADIUS

Dirk van der

The Open Source pioneers have proved during the past few decades that their code and projects can indeed be more solid and popular than commercial alternatives. With data networks always expanding in size and complexity FreeRADIUS is at the forefront of controlling access to and tracking network usage. Although many vendors have tried to produce better products, FreeRADIUS has proved over time why it is the champion RADIUS server. This book will reveal everything you need to know to get started with using FreeRADIUS.FreeRADIUS has always been a back-room boy. It's not easy to measure the size or number of deployments world-wide but all indications show that it can outnumber any commercial alternatives available. This essential server is part of ISPs, universities, and many corporate networks, helping to control access and measure usage. It is a solid, flexible, and powerful piece of software, but can be a mystery to a newcomer.FreeRADIUS Beginner's Guide is a friend of newcomers to RADIUS and FreeRADIUS. It covers the most popular Linux distributions of today, CentOS, SUSE, and Ubuntu, and discusses all the important aspects of FreeRADIUS deployment: Installing, configuring and testing; security concerns and limitations; LDAP and Active Directory integration.It contains plenty of practical exercises that will help you with everything from installation to the more advanced configurations like LDAP and Active Directory integration. It will help you understand authentication, authorization and accounting in FreeRADIUS. It uses many practical step-by-step examples, which are discussed in detail to lead you to a thorough understanding of the FreeRADIUS server as well as the RADIUS protocol. A quiz at the end of each chapter validates your understanding.Not only can FreeRADIUS be used to monitor and limit the network usage of individual users; but large deployments are possible with realms and fail-over functionality. FreeRADIUS can work alone or be part of a chain where the server is a proxy for other institution's users forwarding requests to their servers. FreeRADIUS features one of the most versatile and comprehensive Extensible Authentication Protocol (EAP) implementations. EAP is an essential requirement to implement enterprise WiFi security. FreeRADIUS Beginner's Guide covers all of these aspects.
