Approximately 15% of the global population is affected by some sort of disability, according to the World Report on Disability. Many C-Suite executives perceive digital accessibility (DA) as an endless task. Among the engineering leaders, one in four leaders are reliant on very limited knowledge about digital accessibility. Many countries are increasing their legislative efforts to make web accessibility an important part in web development and testing of software releases. Numerous organizations are facing extreme turbulence when not adhering to international accessibility guidelines while developing their software's and website applications. Web Content Accessibility Guidelines (WCAG) is a global guide on accessibility recommendations that are developed through the World Wide Web Consortium (W3C) to help organizations to meet minimum standard accessibility guidelines. It has become critical for every organization to focus on implementing the accessibility checks at every stage of their application development to avoid costly mistakes. Meanwhile, the need for front-end engineers and Quality Assurance (QA) test analysts to learn WCAG best practices is immensely important for the growing need to incorporate accessibility-focused inclusive design, development, and extensive accessibility testing, which are essential for most of the customer-facing websites. In a fast-paced world, incorporating shift left accessibility within development and testing is the new normal. The Web Accessibility Project: Development and Testing Best Practices helps developers address right accessibility attributes to user interface (UI) components. It also helps developers focus on developing manual and automation tests for QA professionals to inject accessibility audit, accessibility functional tests, and accessibility automation tests as part of their Continuous Integration and Continuous Development (CI/CD) models. The book is filled with readily usable best practices to adapt web accessibility early in application development. By applying the accessibility best practices covered in this book, developers can help their organizations rise to a whole new level of accessibility adherence, innovation, and inclusive design. They will also see greater work satisfaction in their professional lives and a way to help improve digital accessibility for end users.

This volume provides an overview and an understanding of REST (Representational State Transfer). Discussing the constraints of REST the book focuses on REST as a type of web architectural style. The focus is on applying REST beyond Web applications (i.e., in enterprise environments), and in reusing established and well-understood design patterns when doing so. The reader will be able to understand how RESTful systems can be designed and deployed, and what the results are in terms of benefits and challenges encountered in the process.

Since REST is relatively new as an approach for designing Web Services, the more advanced part of the book collects a number of challenges to some of the assumptions and constraints of REST, and looks at current research work on how REST can be extended and applied to scenarios that often are considered not to be a good match for REST.

This work will help readers to reach a deeper understanding of REST on a practical as well as on an advanced level.

Access the power of bare-metal systems programming with Scala Native, an ahead-of-time Scala compiler. Without the baggage of legacy frameworks and virtual machines, Scala Native lets you re-imagine how your programs interact with your operating system. Compile Scala code down to native machine instructions; seamlessly invoke operating system APIs for low-level networking and IO; control pointers, arrays, and other memory management techniques for extreme performance; and enjoy instant start-up times. Skip the JVM and improve your code performance by getting close to the metal. Developers generally build systems on top of the work of those who came before, accumulating layer upon layer of abstraction. Scala Native provides a rare opportunity to remove layers. Without the JVM, Scala Native uses POSIX and ANSI C APIs to build concise, expressive programs that run unusually close to bare metal. Scala Native compiles Scala code down to native machine instructions instead of JVM bytecode. It starts up fast, without the sluggish warm-up phase that's common for just-in-time compilers. Scala Native programs can seamlessly invoke operating system APIs for low-level networking and IO. And Scala Native lets you control pointers, arrays, and other memory layout types for extreme performance. Write practical, bare-metal code with Scala Native, step by step. Understand the foundations of systems programming, including pointers, arrays, strings, and memory management. Use the UNIX socket API to write network client and server programs without the sort of frameworks higher-level languages rely on. Put all the pieces together to design and implement a modern, asynchronous microservice-style HTTP framework from scratch. Take advantage of Scala Native's clean, modern syntax to write lean, high-performance code without the JVM. What You Need: A modern Windows, Mac OS, or Linux system capable of running Docker. All code examples in the book are designed to run on a portable Docker-based build environment that runs anywhere. If you don't have Docker yet, see the Appendix for instructions on how to get it.

Nowadays, Web applications are almost omnipresent. The Web has become a platform not only for information delivery, but also for eCommerce systems, social networks, mobile services, and distributed learning environments. Engineering Web applications involves many intrinsic challenges due to their distributed nature, content orientation, and the requirement to make them available to a wide spectrum of users who are unknown in advance. The authors discuss these challenges in the context of well-established engineering processes, covering the whole product lifecycle from requirements engineering through design and implementation to deployment and maintenance. They stress the importance of models in Web application development, and they compare well-known Web-specific development processes like WebML, WSDM and OOHDM to traditional software development approaches like the waterfall model and the spiral model. .

Ruby is the fastest growing and most exciting dynamic language out there. If you need to get working programs delivered fast, you should add Ruby to your toolbox. This book is the only complete reference for both Ruby 1.9 and Ruby 2.0, the very latest version of Ruby. 2013 marks the 20th anniversary of the Ruby language. We're proud that throughout its history, we've continued to cover the latest version of Ruby. Would you like to go from first idea to working code much, much faster? Do you currently spend more time satisfying the compiler instead of your clients or end users? Are you frustrated with demanding languages that seem to get in your way, instead of getting the work done? Are you using Rails, and want to dig deeper into the underlying Ruby language? If so, then we've got a language and book for you! Ruby is a fully object-oriented language, much like the classic object-oriented language, Smalltalk. Like Smalltalk, it is dynamically typed (as opposed to Java or C++), but unlike Smalltalk, Ruby features the same conveniences found in modern scripting languages such as Perl and Python. The combination of the power of a pure object-oriented language with the convenience of a scripting language makes Ruby a favorite tool of intelligent, forward-thinking programmers. The Pickaxe contains four major sections: * An acclaimed tutorial on using Ruby. * The definitive reference to the language. * Complete documentation of all built-in classes, modules, and methods. * Complete descriptions of all 97 standard libraries. This is the reference manual for Ruby, including a description of all the standard library modules, a complete reference to all built-in classes and modules (including all the new and changed methods introduced by Ruby 1.9, 1.9.2, 1.9.3, and 2.0). It also includes all the new and changed syntax and semantics introduced since Ruby 1.8. Learn about the new parameter passing rules, local variable scoping in blocks, fibers, and the new block declaration syntax, among other exciting new features. About Ruby 2.0 Ruby 2.0 is a minor update to Ruby 1.9, unlike the more major updates from Ruby 1.8 to Ruby 1.9. The major language changes in Ruby 2.0 are the addition of keyword arguments and the change to use UTF-8 as the default source file encoding. There are a number of additions to the standard library, including: * @Enumerator::Lazy@, which adds support for lazy access to potentially infinite lists. * Refinements allow you to encapsulate changes to third-party classes, and scope their application to individual source files, preventing your changes from polluting the global application. You'll also find that Ruby 2 is faster, and has memory management improvements that make it more server-friendly. All told, there are over 110 sections of the book that have been flagged and cross-linked to indicate 2.0 content. What You Need * This book assumes you have a basic understanding of object-oriented programming. * In general, Ruby programmers tend to favor the the command line for running their code, and they tend to use text editors rather than IDEs.
