Accurate Layer Selections Using Photoshop's Selection ToolsTake your hand-drawn illustrations to the next level by using various selection tools in Photoshop to clean up the artwork, and Illustrator for final refinement. Also, learn to save your artwork as vector images to be used for web, print, or even stills for character animation.
Author Jennifer Harder begins by showing you how to use basic tools in Photoshop to clean up your artwork, followed by Marquee tools and more. Next, you will see how to use more advanced tools such as Lasso, Magic Wand, the Object Selection tool, and so on. You'll then get a demonstration of how to control the type of selection using the selection main menu, how to copy selections to another layer, and how to use the focus area. This is followed by a chapter that covers paths, channels, and layer masks that you will master to clean up your artwork.
To round things out, you will learn how to use Illustrator's different features to further enhance your artwork. On completing the book, you will have mastered ...
Software Development Activity CyclesThe principal benefit this book is to provide a holistic and comprehensible view of the entire software development process, including ongoing evolution and support. It treats development as a collaborative effort with triad communication between a tester, a programmer, and a representative from the user community or a Subject Matter Expert (SME). Progress is measured by user acceptance in each cycle before proceeding to the next step of an activity. There is no test stage in the DPAC model: continuous testing is represented in the backswing (Check Phase) of each activity cycle.
This approach posits that there exists some "happy path" that represents the intent of the project as declared by the objectives of a Vision Statement, and that this path can be revealed by an iterative and incremental process of "freeing the statue from the stone." As the image of this path unfolds, more waste is removed while retaining conceptual integrity.
The example presented herein walks the reade ...
Linux for Small Business OwnersLearn how you can take complete control and run your small business with powerful, free open source software (FOSS). This book introduces small business owners to the power and security of Linux and other FOSS tools to manage any small business as well as the many advantages it has over expensive, proprietary software. While exploring the reasons for using Free Open Source Software, you'll investigate the assertion that, "The value of any software lies in its usefulness not in its price," set forth by Linux Torvalds, the creator of Linux.
This book examines the use of Linux and also the other Free Open Source Software you need to meet your business challenges including the usual accounting, Email, web browsing, word-processing tasks. You will be introduced to advanced tools such as those that enable you to create audio and video clips you can use to promote your business or that can even be your primary product, such as how-to instruction.
Most small business owners perform many ...
Learn API TestingExplore software web application architecture, API testing, coding practices, and the standards for better API test automation development and management. This book focuses on aspiring software testing engineers currently working in API testing, and those starting their journey in the field of software testing.
You'll begin with an introduction to API testing and software web applications involving APIs. The book then moves on to the authentication standards used in the software industry, and the tools, the frameworks, and the libraries used in API testing. As the book progresses, you'll learn about the test pyramid, how to test an API, what makes a good test script, and various coding guidelines. Finally, you get to write your own API test script.
Learn API Testing is your pathway to understanding a typical software web application, its requests and responses, and the properties of a good test script. ...
A Treatise on Systems (volume 2)This 2d volume describes the systematic application of Promise Theory to systems, representing a significant step forward in describing functional systems with both dynamics and semantics. By combining quantitative and qualitative descriptions in a single framework, Promise Theory provides the first impartial language for multiscale system phenomena. The closer one is the intrinsic scale of a system component, the more its qualitative semantics dominate its behaviour. As one scales out to large numbers, dynamical patterns dominate the average behaviours.This book serves as guide to graduate students and researchers in the development of a new science of systems, and contains an outstanding number of examples and lessons accumulated over ten years of working in the field, unified by a single theoretical Promise Theoretic model. ...
Kubernetes: Up and Running, 3rd EditionIn just five years, Kubernetes has radically changed the way developers and ops personnel build, deploy, and maintain applications in the cloud. With this book's updated third edition, you'll learn how this popular container orchestrator can help your company achieve new levels of velocity, agility, reliability, and efficiency-whether you're new to distributed systems or have been deploying cloud native apps for some time.
Brendan Burns, Joe Beda, Kelsey Hightower, and Lachlan Evenson-who have worked on Kubernetes at Google and beyond-explain how this system fits into the life cycle of a distributed application. Software developers, engineers, and architects will learn ways to use tools and APIs to automate scalable distributed systems for online services, machine learning applications, or even a cluster of Raspberry Pi computers.
This guide shows you how to: Create a simple cluster to learn how Kubernetes works; Dive into the details of deploying an application using Kubernetes; ...
Foundations of Scalable SystemsIn many systems, scalability becomes the primary driver as the user base grows. Attractive features and high utility breed success, which brings more requests to handle and more data to manage. But organizations reach a tipping point when design decisions that made sense under light loads suddenly become technical debt. This practical book covers design approaches and technologies that make it possible to scale an application quickly and cost-effectively.
Author Ian Gorton takes software architects and developers through the principles of foundational distributed systems. You'll explore the essential ingredients of scalable solutions, including replication, state management, load balancing, and caching. Specific chapters focus on the implications of scalability for databases, microservices, and event-based streaming systems.
You will focus on:
Foundations of scalable systems: Learn basic design principles of scalability, its costs, and architectural tradeoffs
