Firewalls Don't Stop Dragons, 5th EditionRely on this practical, comprehensive guide to significantly improve your cyber safety and data privacy. This book was written expressly for regular, everyday people - though even technically savvy readers will find many useful tips here. This book contains everything you need to protect yourself-step by step, without judgment, and with as little jargon as possible.
Protecting your digital domain is much like defending a medieval castle. Wide moats, towering walls and trained guards provide defense in depth, safeguarding the people and property within against the most common threats. But attempting to dragon-proof your castle would be counterproductive and costly. The goal of this book is to keep your devices and data safe from the most likely and impactful hazards - not a targeted attack by the NSA. Like wearing seat belts and sunscreen in the real world, there are dozens of simple, effective precautions we need to take in the virtual world.

Build Your Own Test FrameworkLearn to write better automated tests that will dramatically increase your productivity and have fun while doing so. This book is a build-your-own adventure designed for individual reading and for collaborative workshops.
You will build an xUnit automated test framework using JavaScript: initially a clone of Jest, but adding a couple of neat features borrowed from RSpec, the genre-defining tool for behavior-driven development (BDD). Along the way, you will explore the philosophy behind automated testing best practices. The automated test runner is one of the most important innovations within software engineering. But for many programmers, automated testing remains a mystery, and knowing how to write good tests is akin to sorcery.
As the chapters of this book unfold, you will see how the humble test runner is an elegant and simple piece of software. Each chapter picks a single feature to build, like the "it" function or the "beforeEach" block. It picks apart the theory of why the ...

Geospatial Analysis with SQLGeospatial analysis is industry agnostic and a powerful tool for answering location questions. Combined with the power of SQL, developers and analysts worldwide rely on database integration to solve real-world spatial problems. This book introduces skills to help you detect and quantify patterns in datasets through data exploration, visualization, data engineering, and the application of analysis and spatial techniques. You will begin by exploring the fundamentals of geospatial analysis where you'll learn about the importance of geospatial analysis and how location information enhances data exploration. Walter Tobler's second law of geography states, "the phenomenon external to a geographic area of interest affects what goes on inside." This quote will be the framework of the geospatial questions we will explore. You'll then observe the framework of geospatial analysis using SQL while learning to create spatial databases and SQL queries and functions. By the end of this book, yo ...
