It's easy to write correct Ruby code, but to gain the fluency needed to write "great "Ruby code, you must go beyond syntax and absorb the "Ruby way" of thinking and problem solving. In "Eloquent Ruby, "Russ Olsen helps you write Ruby like true Rubyists do-so you can leverage its immense, surprising power. Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the "Ah Ha " moments when it suddenly becomes clear why Ruby works the way it does, and how you can take advantage of this language's elegance and expressiveness." Eloquent Ruby "starts small, answering tactical questions focused on a single statement, method, test, or bug. You'll learn how to write code that actually looks like Ruby (not Java or C#); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for. Next, the book addresses bigger questions related to building methods and classes. You'll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code-and why you'll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages. A part of the renowned Addison-Wesley Professional Ruby Series, "Eloquent Ruby "will help you "put on your Ruby-colored glasses" and get results that make you a true believer.

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.

Enterprises have made amazing advances by taking advantage of data about their business to provide predictions and understanding of their customers, markets, and products. But as the world of business becomes more interconnected and global, enterprise data is no long a monolith; it is just a part of a vast web of data. Managing data on a world-wide scale is a key capability for any business today. The Semantic Web treats data as a distributed resource on the scale of the World Wide Web, and incorporates features to address the challenges of massive data distribution as part of its basic design. The aim of the first two editions was to motivate the Semantic Web technology stack from end-to-end; to describe not only what the Semantic Web standards are and how they work, but also what their goals are and why they were designed as they are. It tells a coherent story from beginning to end of how the standards work to manage a world-wide distributed web of knowledge in a meaningful way. The third edition builds on this foundation to bring Semantic Web practice to enterprise. Fabien Gandon joins Dean Allemang and Jim Hendler, bringing with him years of experience in global linked data, to open up the story to a modern view of global linked data. While the overall story is the same, the examples have been brought up to date and applied in a modern setting, where enterprise and global data come together as a living, linked network of data. Also included with the third edition, all of the data sets and queries are available online for study and experimentation at data.world/swwo.
