This book is an in-depth learning and teaching resource for the understanding and programming of TCP/IP networking in Java. It covers 'everything you can do to a socket in Java' and explains when and why you might - or might not - want to do that. It is addressed both to professional programmers and college students in first or second year networking courses. The book covers TCP and UDP using both blocking streams and non-blocking channels, and also SSL secure sockets in both blocking and non-blocking modes, unravelling the mysteries of the SSLEngine in the process. Particular attention is paid to the neglected topics of multi-homing and multicast. A unique chapter on client and server architectures uses a quantitative approach rather than the usual design-patterns approach, leading to architectures with predictable performance rather than just coding elegance. All you need to know about: - Using Streams and Sockets for blocking TCP/IP - Using Buffers and Channels for non-blocking and multiplexed TCP/IP and UDP - Designing servers for scalability and predictable performance - Working with blocking TLS/SSL using Streams and SSLSockets - Unlocking the mysteries of non-blocking TLS/SSL with the JDK 1.5 SSLEngine - Using DatagramSockets and DatagramPackets for blocking UDP and multicasting - Outlining special programming considerations for multihomed hosts - Managing the transition from IPv4 to IPv6 in Java Features: - Extensive Java index - Accompanying [SVL] website XXXXX with source code download - Comprehensive code samples and some exercises. Esmond Pitt is a Melbourne consultant and author with a distinguished 28-year international career in the design and implementation of systems software products. A well-known Java advisor, he has published a book on Java RMI, and is a member of Sun's Expert Group on Distributed Real-time Java. His IT practice encompasses compiler construction, networking, and security. He is a Fellow of the Australian Computer Society. I was an early reviewer of this book and I admire its economical and thorough but eminently readable style, lucidly describing complex issues without ever outstaying its welcome. This book combines academic rigour with a practical approach deeply informed by real-world experience and I have no hesitation in recommending it to developers of all experience levels. Experienced engineers building network-centric infrastructure or services should not be without this book. In fact, any Java developer building distributed applications such as J2EE, Jini, and Web Services should read this book — at least to understand the fundamental implications of networking on application design and implementation. Michael Geisler, Sun Microsystems.

Discover how stronger types mean cleaner, more efficient, and optimized PHP applications. This unique book looks at typed PHP: PHP types, strings, regular expressions, and more from PHP 7 as found in standard PHP libraries, user libraries, extensions, and cross-compilers. You'll see how to create a set of reusable tools that unify and ease the scalar types of PHP. PHP has a rich history and a dominant place on the web. It has achieved much despite language inconsistencies and difficulties. Bjarne Stroustrup once said: "There are only two kinds of languages: the ones people complain about and the ones nobody uses". PHP is one of those languages that everybody uses, yet that's often seen as a good reason to ignore the bad parts and just get stuff done. We're all for getting stuff done, and to that end, the author has used Plain Ol' PHP for many years. It's always bugged him how procedural PHP is, in an ecosystem of OOP libraries and frameworks. So he decided to take a deeper look at building a stronger type system on top of PHP. That's the goal of this book. What You'll Learn Discover the fundamentals of PHP strings, regex, underscores, native function inconsistencies, and more Examine the structure of PHP types including boxing, regex, namespace functions, composer autoload, null problem, optional values, and more Work with extensions like vagrant + phansible, provisioning, vagrant commands, SPL types, scalar objects, zephir, and more Design using scalar, SPL, zephir, structure types, resolving types, chaining, combining number types, PHPUnit, packaging, and more Plan for the future using a case study example.

Learn everything you need to master the AdonisJs framework, including topics such as interacting with a database, rendering templates, writing asynchronous code, and hosting sites with SSL. Along the way, you’ll see how to build a commerce application, which lists products and allows shoppers to register and purchase those products. The site will feature a product catalog, a shopping cart, user registration and login, and profile management. The Definitive Guide to AdonisJs also covers how to create a front-end build chain, so that you can use a modern front-end framework, such as React. You’ll discover how to connect your front end to the server, so that data and transactions can be shared between the two. Finally, you’ll see how to secure and deploy the application to a virtual private server, including how to apply for and install an SSL certificate and start accepting payments. After reading and using this book, you’ll know all you need about AdonisJs. You’ll have the tools to turn that side-project you’ve been thinking about into a real money-making product. It is written by a web expert and reviewed by the AdonisJs project lead. This is the complete start-to-finish guide you’ve been waiting for. You will: Set up Node.js and AdonisJs, so that you can start building your application Create and use views and template code Implement cooperative multitasking, in JavaScript Represent eventual values with AdonisJs promises Organize and isolate your code in controllers and decorate them with middleware, to do things like authentication Build queries, using the Lucid DSL, and package these database entities up into model classes Validate form data and respond with the appropriate error messages Respond to general framework errors with custom error pages Learn the deeper parts of sessions and cookies Update the state of the user interface with WebSockets Host AdonisJs applications in a modern hosting environment.

We are increasingly seeing computer systems which are expected to function without operator intervention. This is perhaps acceptable for running computer networks or traffic lights; however, we are now seeing computer systems deployed to qualitatively influence human judgments such as rulings on legal disputes or fitness for work to evaluate disability benefits. In keeping with the precautionary principle, it is important that those who are developing this capability - technologists and scientists - think through its potential implications. The aim of this book is to explore the technological
