Gain insight into how hexagonal architecture can help to keep the cost of development low over the complete lifetime of an application Key FeaturesExplore ways to make your software flexible, extensible, and adaptableLearn new concepts that you can easily blend with your own software development styleDevelop the mindset of building maintainable solutions instead of taking shortcutsBook Description We would all like to build software architecture that yields adaptable and flexible software with low development costs. But, unreasonable deadlines and shortcuts make it very hard to create such an architecture. Get Your Hands Dirty on Clean Architecture starts with a discussion about the conventional layered architecture style and its disadvantages. It also talks about the advantages of the domain-centric architecture styles of Robert C. Martin's Clean Architecture and Alistair Cockburn's Hexagonal Architecture. Then, the book dives into hands-on chapters that show you how to manifest a hexagonal architecture in actual code. You'll learn in detail about different mapping strategies between the layers of a hexagonal architecture and see how to assemble the architecture elements into an application. The later chapters demonstrate how to enforce architecture boundaries. You'll also learn what shortcuts produce what types of technical debt and how, sometimes, it is a good idea to willingly take on those debts. After reading this book, you'll have all the knowledge you need to create applications using the hexagonal architecture style of web development. What you will learnIdentify potential shortcomings of using a layered architectureApply methods to enforce architecture boundariesFind out how potential shortcuts can affect the software architectureProduce arguments for when to use which style of architectureStructure your code according to the architectureApply various types of tests that will cover each element of the architectureWho this book is for This book is for you if you care about the architecture of the software you are building. To get the most out of this book, you must have some experience with web development. The code examples in this book are in Java. If you are not a Java programmer but can read object-oriented code in other languages, you will be fine. In the few places where Java or framework specifics are needed, they are thoroughly explained.

This volume brings together a decade of reflection at the intersection of culture, economics, and theology. Addressing topics ranging from the family to work, politics, and the church, Jordan J. Ballor shows how the Christian faith calls us to get involved deeply and meaningfully in the messiness of the world. Drawing upon theologians and thinkers from across the great scope of the Christian tradition, including Augustine, Thomas Aquinas, Martin Luther, Abraham Kuyper, and Dietrich Bonhoeffer, and engaging a variety of current figures and cultural phenomena, these essays connect the timeless insights of the Christian faith to the pressing challenges of contemporary life.

This book is not for beginners. It does not teach you how to move around worksheets; neither does it teach you how to copy the contents of one cell to the other. The book assumes that you have worked with Excel for at least six months. We start by introducing you to the Ribbon and how to customize the user interface. You learn how to automate worksheet operations with macros. We take you through creating custom formats, data validation, worksheet outlines, data consolidation, error checking, etc. We look at intermediate and advanced functions such as Indirect, Match, Find, etc. and show you how to combine these functions to solve real-world problems. We discuss business models and apply statistical and financial functions. The rest of the topics we treat include using table formulas, creating range names, using names for formulas, Date and Time functions, error checking, workbook/worksheet protection, etc. We look at the Lookup functions (Vlookup, Hlookup, etc.) and the functions that can be used in lieu of the lookup functions to perform more complex lookups. Every chapter of the book contains exercises to reinforce your learning experience. We believe that practice makes perfect, so at the end of the book, we provide you with over 120 hands-on exercises (step-by-step answers provided). We guarantee that after going through all the exercises in the book, you will be on your way to becoming an Excel expert.

In Painting the Psalms, artist Cherie Burbach shares original, mixed-media paintings that contain a positive, faith-filled message. Each painting contains inspiration from the Psalms in some way, through the imagery, words, or emotion contained within the verses. Cherie uses a variety of mediums and techniques to create art that is filled with depth and whimsy. It is her hope that this book will inspire you to look at the Psalms in a new way so you can celebrate your faith and believe in the message. Some of the paintings were created during Cherie’s popular “Painting the Psalms” series of ecourses, where she demonstrates step-by-step progress from start to finish, including all the small details that make mixed media paintings come alive with texture and color.
