Paperback. Zustand: new. Paperback. At the heart of Silicon Valley's meteoric rise is a story etched in the lives of those who shaped it and those who were forever transformed by it. Author Tom Mahon provides an insider's perspective on the birth of the semiconductor industry, which sparked the region's transformation from sleepy farmland to the heart and soul of the high-tech revolution. Through twenty-five extended, in-person interviews you'll meet a diverse cast of characters whose goal was to create technology and tools in service to humanity. In the Afterword to this edition, the author questions whether they accomplished their objectives and urges readers to rise up and rethink technology.What did it take to create the atmosphere that transformed rich farmland into the wealthy center of high-tech? Five climates lined up in just the right way. Educational institutions (Stanford and Berkeley); an attractive location with balmy, Mediterranean-like weather; a history of technology development (Federal Telegraph in the early twentieth century); financial risk taking (the gold rush); and a cultural climate near the center of an ideological revolution (the hippie movement). The Santa Clara Valley had them all. In spades.Before personal computers, or the Internet, or social media came *chips*. Inventive minds took advantage of the quad-electron structure and unique properties - insulative and conductive - of silicon to create semiconductors. But Charged Bodies is more than just the story of new technologies emerging from "The Valley of the Heart's Delight." Using an approach like The Canterbury Tales, Tom Mahon captures the spirit of Silicon Valley in the 80s through the stories of the people all around him. The inventors and bankers have their say. But so do a range of other people who lived through that transition. Listen as artists and hackers, detectives and journalists, lawyers and scientists, flappers and philosophers tell the story of Silicon Valley in their own words. Author Tom Mahon provides an insider's perspective on the birth of the semiconductor industry, which sparked the region's transformation from sleepy farmland to the heart and soul of the high-tech revolution.

Isolation forced on them by the pandemic, combined with America's growing political factionalism, threatened their bonds with community and family. Something had to change. Maggie's surprising answer: buy a boat, learn to pilot it, and embark on the Great Loop. For nine months Bruce and Maggie navigated rivers, coastal waters, lakes, locks, and loss. Against all odds, they conquered the Loop, and along the way found common cause across political divides with new friends while blowing the walls off their world.Bruce and Maggie Tate were spiraling downward. Normally outgoing and cheerful, Maggie was broken down by pandemic isolation. Bruce, facing asthma, heart disease and Covid-related professional issues, was sure that the virus and his comorbidities would kill him. And the plant-based diet he had just started made him wish it would hurry up. Meanwhile, their country seemed to be crumbling into warring factions.That was when Maggie made a life-changing decision. With no experience, knowing little about seafaring, inboard motors, or navigation, she and Bruce and the family dog decided to take on the Great Loop, a six-thousand-mile journey down inland rivers, around the Gulf and Atlantic coasts, and across the Great Lakes. They had to navigate canals and locks, were threatened by dangerous seas, and even had to deal with heartbreaking loss. But along the way, they made new lifelong friends and were forever changed.When, in a time of great divisiveness, two broken people took on the challenge of their lives, against all odds they found common cause across political divides and made themselves whole again. For nine months Bruce and Maggie navigated rivers, coastal waters, lakes, locks, and loss. Against all odds, they conquered the Loop, and along the way found common cause across political divides with new friends while blowing the walls off their world.

Paperback. Zustand: new. Paperback. Workplace 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. 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.

Paperback. Zustand: new. Paperback. htmx 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. htmx 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.

Paperback. Zustand: new. Paperback. htmx 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. htmx 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.
