This new edition of the book covers Tailwind 3.0, which changes the way Tailwind generates its CSS. Tailwind 3.0 has a large number of new features powered by the new system, including the ability to use arbitrary values with most Tailwind class patterns, and a new syntax for combining color and opacity in a single class. This book also covers the new standalone command-line tools for Tailwind. With CSS, you can do amazing things to the basic text and images on your website, and with just a little bit of client-side code to add and remove CSS classes, you can do exponentially more. In the latest edition of this book, you'll learn how to use Tailwind 3.0 and the new way it generates CSS. You'll code your way through Tailwind's newest features, including the ability to use arbitrary values with most Tailwind class patterns and a new syntax for combining color and opacity in a single class. You'll even dive into the new standalone command-line tools for Tailwind. The Tailwind setup is extremely explicit and makes it possible to understand the display just by looking at the HTML markup. Start by designing the typographic details of the individual elements, then placing and manipulating those elements in "the box" using a flexbox or grid design. Finally, move those elements around the page with helpful small animations and transitions. With Tailwind, it's easy to prototype, iterate, and customize your display, use prefixes to specify behavior, change defaults, add new behavior, and integrate with legacy CSS. Use Tailwind to make extraordinary web designs without extraordinary effort. What You Need: This book is about Tailwind 3.0. You should have a basic knowledge of CSS and HTML.

The Rust programming language is consistent and does its best to avoid surprising the programmer. Like all languages, though, Rust still has its quirks. But these quirks present a teaching opportunity. In this book, you'll work through a series of brain teasers that will challenge your understanding of Rust. By understanding the gaps in your knowledge, you can become better at what you do and avoid mistakes. Many of the teasers in this book come from the author's own experience creating software. Others derive from commonly asked questions in the Rust community. Regardless of their origin, these brain teasers are fun, and let's face it: who doesn't love a good puzzle, right? What better way to exercise your brain and increase your Rust programming knowledge than with a collection of dynamic brain teasers? As you read through each of these puzzles and try to work out the answers, you'll not only learn about Rust's unique quirks and peculiarities, you'll also have loads of fun along the way. Dive right in and get started with example code and sample problems that cover numbers and text, shadowing and memory, and everything in between. Try to figure out why a particular program won't compile, why it produces unexpected output, or why it panics and terminates with an error message. Once you've run the code and read the answer, it's time to get to the heart of the matter with a detailed explanation. Learn why a program produced the result it did, and discover how similar issues might affect the code you write in your own programs, even in production. Sourced from engaging discussions within the Rust community, real-world problems, and even reader feedback, these challenges will certainly surprise, enlighten, and entertain you. Are you ready to experience Rust like never before? Then sharpen your brain and get ready for a challenge! What You Need: This book assumes you have some knowledge of the Rust programming language. To work through the brain teasers in this book, you'll need a working Rust environment on any platform. You can install Rust by visiting https: //rustup.rs/.

This textbook grew out of notes for the ECE143 Programming for Data Analysis class that the author has been teaching at University of California, San Diego, which is a requirement for both graduate and undergraduate degrees in Machine Learning and Data Science. This book is ideal for readers with some Python programming experience. The book covers key language concepts that must be understood to program effectively, especially for data analysis applications. Certain low-level language features are discussed in detail, especially Python memory management and data structures. Using Python effectively means taking advantage of its vast ecosystem. The book discusses Python package management and how to use third-party modules as well as how to structure your own Python modules. The section on object-oriented programming explains features of the language that facilitate common programming patterns. After developing the key Python language features, the book moves on to third-party modules that are foundational for effective data analysis, starting with Numpy. The book develops key Numpy concepts and discusses internal Numpy array data structures and memory usage. Then, the author moves onto Pandas and details its many features for data processing and alignment. Because strong visualizations are important for communicating data analysis, key modules such as Matplotlib are developed in detail, along with web-based options such as Bokeh, Holoviews, Altair, and Plotly. The text is sprinkled with many tricks-of-the-trade that help avoid common pitfalls. The author explains the internal logic embodied in the Python language so that readers can get into the Python mindset and make better design choices in their codes, which is especially helpful for newcomers to both Python and data analysis. To get the most out of this book, open a Python interpreter and type along with the many code samples.

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.

Based on the latest version of the language, this book offers a self-contained, concise and coherent introduction to programming with Python. The book's primary focus is on realistic case study applications of Python. Each practical example is accompanied by a brief explanation of the problem-terminology and concepts, followed by necessary program development in Python using its constructs, and simulated testing. Given the open and participatory nature of development, Python has a variety of incorporated data structures, which has made it difficult to present it in a coherent manner. Further, some advanced concepts (super, yield, generator, decorator, etc.) are not easy to explain. The book specially addresses these challenges; starting with a minimal subset of the core, it offers users a step-by-step guide to achieving proficiency.

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.

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.
