eBook Description: Web Programming with HTML5, CSS, and JavaScript Web Programming with HTML5, CSS, and JavaScript is written for the undergraduate, client-side web programming course. It covers the three client-side technologies (HTML5, CSS3, and JavaScript) in depth, with no dependence on server-side technologies. One of the distinguishing features of this new text is its coverage of canvas, one of the most important new features of HTML5. Topics are presented in a logical, comprehensive manner and code is presented in both short code fragments and complete web pages, allowing readers to grasp concepts quickly and then apply the concepts in the context of a complete web page. Each chapter concludes with an optional case study, which builds upon itself to create a sophisticated website. The case studies allow students to apply what they have learned and gives them a feel for the real-world design process.

Learning Perl 6: Keeping the Easy, Hard, and Impossible Within Reach

Swift Language is now more powerful than ever; it has introduced new ways to solve old problems and has gone on to become one of the fastest growing popular languages. It is now a de-facto choice for iOS developers and it powers most of the newly released and popular apps. Learn Swift by Building Applications will help you to begin your journey with Swift programming through learning how to build iOS apps. You will learn all about basic variables, if clauses, functions, loops, and other core concepts; then structures, classes, and inheritance will be discussed. Next, you’ll dive into developing a weather app that consumes data from the internet and presents information to the user. The final project is more complex, involving creating an Instagram like app that integrates different external libraries. The app also uses CocoaPods as its package dependency manager, to give you a cutting-edge tool to add to your skillset. By the end of the book, you will have learned how to model real-world apps in Swift.

eBook Description: Google Cloud Platform Administration: Make the most of GCP’s offerings to manage your data center workload and optimize deployments Google Cloud Platform Administration begins with GCP fundamentals, with the help of which you will deploy your first app and gain an understanding of Google Cloud architecture and services.
