Mother Nature & Her Human Friends
by John KixMillerMother Nature and Her Human Friends is a narrative poem. The characters include Will, a twenty-year-old, who works for Miller, the landscaper of the Bonvern Valley Park. Will discovers a cave of vines and a hidden pool, and, tired of his studio apartment, spends the night in the cave with his dog Hilda. He has a dream vision of Mother Nature, who speaks to him and creates a new direction for his life. A day later, Will meets Linda in the cave, and together they gather a new group called Mother Nature's Friends. They build a network to save the forest and the wetland in their valley, and risk their lives to protect the living beauty around them. &“I&’ve worked all my life trying to re-envision who we are and what nature is and can be. The idea that nature has no soul is a travesty, a monstrous loss of our identity. But now I see a different goal, a new role for us to play.&”– Lisa Nieves, Parks Commissioner for Bonvern Valley

Serverless Apps on Cloudflare
by Ashley PeacockUse serverless technologies to build applications that scale, more quickly and easily, and without worrying about deployment. Whether you're writing an API, a full-stack app, or real-time code, harness the power of serverless on Cloudflare's platform so you can focus on what you do best: delivering solutions. With hands-on instruction and code samples throughout, you'll go from building a simple API to analyzing images with AI. And, when it's time to launch, you'll learn how to deploy your applications and websites automatically, and how to optimize their performance for production. For decades, applications have been built and deployed in a similar way: you write code, provision a server, and upload your code. Over the years, you've graduated from FTP or SSH to Docker and Kubernetes, but fundamentally you've just switched from owning to renting; you're paying 24/7 for the server hosting your app. Serverless technologies change that model. With serverless, you focus on writing code, and not how it's deployed. You only pay for when your application code is executed, rather than paying for idle servers. In this book we'll use Cloudflare, which was built from the ground up to be a serverless platform, but the same concepts apply to every serverless provider. With this book, you'll learn a better way to build applications, and you'll see improved productivity and ease of deployment. From secrets to dependencies, such as databases and caches, Cloudflare has revolutionized how to build applications, and has made building applications easier and more fun. As you go through the book, you'll learn in detail what serverless is, how it functions behind the scenes, and how to build serverless applications on Cloudflare. When you finish this book, you'll understand how to think in terms of serverless functions, and you'll have the experience of deploying and extending these apps as you work through the examples. What You Need: Mac or PCGitHub account (free)Cloudflare account (free)

Server-Driven Web Apps with htmx
by R. Mark Volkmannhtmx is a library that adds logic and server interaction to HTML; you get the effect of using a front-end SPA framework without writing front-end code. Use any server-side programming language and framework to build server applications with endpoints that simply return snippets of HTML. Dynamically update portions of the current web page from HTTP responses. Add interactivity with JavaScript and libraries such Alpine and _hyperscript. Make your apps more secure by escaping user-supplied content and specifying a Content Security Policy. Go beyond basic HTTP requests with WebSockets and server-sent events. The htmx JavaScript library gives you a new way to craft web applications. The htmx approach differs significantly from that of the currently popular single-page application (SPA) frameworks; rather than write a bunch of JavaScript, you simply annotate HTML elements before you send them to the browser. The resulting code is easier to understand and modify, and because it downloads less to the browser and doesn't need JSON creation and parsing, you'll find it performs better, too. Rethink web application design; write code in any language that simply responds to requests with htmx snippets.Dynamically update portions of the current web page directly from the server.Implement common patterns such as lazy loading, input validation, CSS transitions, active search, optimistic updates, pagination, infinite scroll, polling, and click-to-edit.Add interactivity with JavaScript and libraries such as Alpine and _hyperscript.Use the htmx JavaScript API to simplify DOM operations.Make your web apps more secure: escape user-supplied content, use Subresource Integrity hashes, and enforce a Content Security Policy.Go beyond the basic HTTP request/response pattern with WebSockets and server-sent events.Discover a simpler way to implement web applications that emphasizes web fundamentals.What You Need:A modern web browser and the ability to build and run a local HTTP server using the server-side language and framework of your choice.The code examples are fully compatible with htmx 2.0.
The Stress Equation
by Marcus LagreWorkplace stress is not the weakness of individuals; it's caused by systemic problems. Armed with the insights in this book, you can identify, analyze, and systematically reduce the factors that lead to poor health, low productivity, and personal burnout. This book gives you a framework for understanding stress, and a vocabulary to make it easier to discuss it among colleagues. Stress can be fixed; find out how. The interviewer asks, "How well do you cope with stress?" Your response should be, "Let's fix your environment so we don't have to." Work-related stress is one of the leading causes of mental illness among white-collar workers. It hurts companies, projects, and (most importantly) people! Stress is a burden that's created when teams stop working well. The Stress Equation is a model and a tool to help talk about stress as a systemic issue. By exploring how pressure, complexity, and security interact in software teams, we move focus away from the individual, so that we can talk about stress from a team and organizational perspective. By exploring external factors, we discuss how to solve problems rather than cope with the consequences. Whether you're an individual feeling stressed or a manager who can help, you'll learn the causes of, fixes for, and how to talk about stress. We regulate pressure by how we decide how much work we have to do and when it needs to be finished. Complexity is decided by how we handle our product and organization design. Our security is less about our pay and benefits, and more about the support and trust we feel.Stress should not be a given. Instead, it's a symptom of a diseased organization. With this book, you can begin the healing process.What You Need:No special requirements.
