Instant OSGi Starter. The essential guide to modular development with OSGi
Johan Edstrom, Johan Edstorm, Jamie Goodyear
OSGi is a tried and true modularity standard for Java. It has in recent years gained a lot of traction and tooling; becoming frequently used in Enterprise containers and distributed software systems. Instant OSGi Starter is where you should start before beginning your first OSGi based project. You'll be exposed to the core concepts, gain practical experience with the most important features, and learn about the basic tenets of modular code practices. This book begins with the fundamental tools needed for building modular applications, top features with basic tenets of modular core practices and provides useful insights into resources and the community.As this book progresses you will be able to get started programming in OSGi whilst looking at the default three layer design so the application will be architected towards modularity and simplicity.Through exploring several tools and technologies and browsing the communities you will be able to work towards modular programming in OSGi.

Security software is often expensive, restricting, burdensome, and noisy. OSSEC-HIDS was designed to avoid getting in your way and to allow you to take control of and extract real value from industry security requirements. OSSEC-HIDS is a comprehensive, robust solution to many common security problems faced in organizations of all sizes.Instant OSSEC-HIDS is a practical guide to take you from beginner to power user through recipes designed based on real- world experiences. Recipes are designed to provide instant impact while containing enough detail to allow the reader to further explore the possibilities. Using real world examples, this book will take you from installing a simple, local OSSEC-HIDS service to commanding a network of servers running OSSEC-HIDS with customized checks, alerts, and automatic responses.You will learn how to maximise the accuracy, effectiveness, and performance of OSSEC-HIDS' analyser, file integrity monitor, and malware detection module. You will flip the table on security software and put OSSEC-HIDS to work validating its own alerts before escalating them. You will also learn how to write your own rules, decoders, and active responses. You will rest easy knowing your servers can protect themselves from most attacks while being intelligent enough to notify you when they need help!You will learn how to use OSSEC-HIDS to save time, meet security requirements, provide insight into your network, and protect your assets.

PageSpeed is an important aspect of web design and site management. It is a Google measure of how well the site performs to technical measurements. PageSpeed can be measured using Google's own tool or a browser plugin. It is used to score sites in indices, and is important from a UI view as it forms a large part of the success of your site.Instant PageSpeed Optimization is a practical, hands-on guide that provides you with a number of clear, step-by-step exercises, which will help you to take advantage of the real power that is behind web optimization techniques, and give you a good grounding in using it in your websites.The book explores topics like HTML standards used for optimization, minifying scripts, and taking care of images, and solves the common errors that users do unknowingly. It will take you through a number of clear, practical recipes that will help you to take advantage of all the possible technologies to make your websitess efficient, fast, and accurate. You will not only learn basic standards to optimize your websites, but you will also learn some advanced level methods such as Apache handling, Flush methods, making AJAX cacheable, setting up browser caches, and reducing image size using CSS sprites.If you want to take advantage of all the necessary methods to make your website faster and efficient, then this book is a must-have.

Many of today's applications need to be able to process large volumes of data, and vertical scaling has its limits both in terms of prohibitive cost and hardware limits. Gearman is an open source job manager that is well-suited to building horizontally scalable systems, from map-reduce algorithms to simple data processors capable of handling massive amounts of information.Instant Gearman is a practical, hands-on guide to getting started with building an open source job management server system that is built to grow. Learn the basics of building a distributed application that spans multiple components and learn how Gearman fits into building an application that scales from one to hundreds of components that interact to process data. With Gearman, you can build software that scales horizontally as your need for computation increases.Instant Gearman has in-depth examples and a step-by-step approach to building distributed systems, helping you to build systems that are scalable and modular in their approach to processing data.Once you are comfortable with building simple workers and clients, learn how to build a cluster of managers and see how to reduce single-point-of-failure in your architecture. Next, build a simple map-reduce application using Gearman and scale it up from a single instance to multiple parallel processing components.

Play is a full-featured Java and Scala web framework for building modern, high-performance web applications. It is characterized by its simplicity and scalability. With its lightweight, stateless, and web-friendly architecture, Play focuses on developer experience to make web application development fun.Instant Play Framework Starter is the ideal companion to start developing web applications with Play. The building blocks of a typical web application are carefully designed following an on-going example.Instant Play Framework Starter starts with a quick setup and running a first sample. Then, the anatomy of a typical Play application is outlined. More features are added step by step to an example application. The result is the prototype of a highly scalable web application.The example is implemented in Java and in Scala. It consists of building blocks you will find in every Play application. In particular, you will learn how views are rendered with the template engine, how HTTP routes are used to define the navigation rules, and how to separate the application logic of controllers from the business logic of the model. This separation is the result of a careful application design, which makes it easy to add features like data binding and validation. Finally you will see how easy it is to adapt different database access libraries.Instant Play Framework Starter will help you to get started with Play and develop your first application. Packed with examples, it is easy to follow the design of a real-world application. You are able to compare the difference between a Java- and a Scala-based Play application and to decide which language fits your needs best. All topics covered in the book are described with the aim to serve as a reference for future web application development with Play.
