SVG Colors, Patterns & Gradients
As a vector graphics format, SVG uses precisely-defined geometric shapes to build an image. But that doesn't mean that SVG graphics have to look like technical drawings. SVG graphics can be shaded, textured, built from partially-transparent overlapping layers, or even filled with photographic images. SVG Colors, Patterns and Gradients takes an in-depth look at the different ways SVG text and shapes can be painted on the screen or page. You'll start with an overview of how color is defined, including the various ways you can control the transparency of SVG content. You'll then dive deep into the concept of an SVG paint server: gradients, patterns and other complex graphical content that can be used to fill-in or outline other SVG shapes and text. ...

Swift 2 Design Patterns
Swift is a multi-paradigm language. It has expressive features familiar to those used to work with modern functional languages, while also keeping the object-oriented features of Objective-C. It remains compatible with Apple's legacy codes and frameworks. A design pattern systematically names, motivates, and explains a general design that addresses a recurring design problem in object-oriented systems. It describes the problem, the solution, when to apply the solution, and its consequences. It also gives implementation hints and examples. Knowledge about design patterns is also one of the best ways to make you different compared to other low-level developers. This book shows you how to use Swift 2 to learn about 23 Gang of Four (GoF) design patterns and is organized into three categories. The book will present you the five creational patterns followed by the seven structural patterns and finishing with the 11 behavioral patterns as defined by the G ...

Scala Functional Programming Patterns
Scala is used to construct elegant class hierarchies for maximum code reuse and extensibility and to implement their behavior using higher-order functions. Its functional programming (FP) features are a boon to help you design “easy to reason about” systems to control the growing software complexities. Knowing how and where to apply the many Scala techniques is challenging. Looking at Scala best practices in the context of what you already know helps you grasp these concepts quickly, and helps you see where and why to use them. This book begins with the rationale behind patterns to help you understand where and why each pattern is applied. You will discover what tail recursion brings to your table and will get an understanding of how to create solutions without mutations. We then explain the concept of memorization and infinite sequences for on-demand computation. Further, the book takes you through Scala's stackable traits and dependency injection, a popular technique to ...

Calm Technology
How can you design technology that becomes a part of a user's life and not a distraction from it? This practical book explores the concept of calm technology, a method for smoothly capturing a user's attention only when necessary, while calmly remaining in the background most of the time. You'll learn how to design products that work well, launch well, are easy to support, easy to use, and remain unobtrusive. Author Amber Case presents ideas first introduced by researchers at Xerox PARC in 1995, and explains how they apply to our current technology landscape, especially the Internet of Things. This book is ideal for UX and product designers, managers, creative directors, and developers. ...

Cloud Design Patterns
Cloud applications have a unique set of characteristics. They run on commodity hardware, provide services to untrusted users, and deal with unpredictable workloads. These factors impose a range of problems that you, as a designer or developer, need to resolve. Your applications must be resilient so that they can recover from failures, secure to protect services from malicious attacks, and elastic in order to respond to an ever changing workload. This guide demonstrates design patterns that can help you to solve the problems you might encounter in many different areas of cloud application development. Each pattern discusses design considerations, and explains how you can implement it using the features of Windows Azure. The patterns are grouped into categories: availability, data management, design and implementation, messaging, performance and scalability, resilience, management and monitoring, and security. You will also see more general guidance related to these areas o ...
