Taschenbuch. Zustand: Neu. Neuware - 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 u…nderstanding 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.

Taschenbuch. Zustand: Neu. Neuware - Take control of your home and your data with the power of the Go programming language. Build extraordinary and robust home automation solutions that rival much more expensive, closed commercial alternatives, using the same tools found in high-end enterprise computing environments. Best-sellin…g Pragmatic Bookshelf authors Ricardo Gerardi and Mike Riley show how you can use inexpensive Raspberry Pi hardware and excellent, open source Go-based software tools like Prometheus and Grafana to create your own personal data center. Using the step-by-step examples in the book, build useful home automation projects that you can use as a blueprint for your own custom projects.With just a Raspberry Pi and the Go programming language, build your own personal data center that coordinates and manages your home automation, leveraging the same high-powered software used by large enterprises. The projects in this book are easy to assemble, no soldering or electrical engineering expertise required.Build a temperature monitor that can send alerts any time defined thresholds are exceeded and report the temperature readings on a time-based series chart. Change the color of lights to visually indicate the current outdoor weather status. Create a networked motion detector that triggers an alert any time motion is detected, such as a door opening or closing, a pet wandering around, or deliveries or visitors arriving on your front porch. Even have these triggers initiate a more complex Go-based automation sequence. Integrate a small, high-resolution camera into a bird feeder that takes excellent, up-close photos whenever a bird perches at the feeder, and broadcasts them to your Discord server where your family and friends can see these wildlife captures in real time.Control your home with hardware you configure, and manage it with Go code that you create and modify any time you want to enhance your home automation capabilities.What You Need:Readers should be familiar with the Go programming language and have working knowledge of Linux. Free, open source Go-based libraries and utilities are available for download from the Internet. Readers will also need a working Raspberry Pi 3+ or higher, and a Pi Pico W microcontroller. Several other inexpensive electronic parts (touch sensors, motion detectors) are also needed for some of the projects. A Philips Hue base lighting system is also needed for the weather monitor project.

Taschenbuch. Zustand: Neu. Neuware - Build your own video chat application - but that's just the beginning. With WebRTC, you'll create real-time applications to stream any kind of user media and data directly from one browser to another, all built on familiar HTML, CSS, and JavaScript. Power real-time activities like text-based…chats, secure peer-to-peer file transfers, collaborative brainstorming sessions - even multiplayer gaming. And you're not limited to two connected users: an entire chapter of the book is devoted to engineering multipeer WebRTC apps that let groups of people communicate in real time. You'll create your own video conferencing app. It's all here.WebRTC is an API exposed in all modern web browsers. After almost a decade of development, the WebRTC specification was finalized, and this book provides faithful coverage of that finalized specification. You'll start by building a basic but complete WebRTC application for video chatting. Chapter by chapter, you'll refine that app and its core logic to spin up new and exciting WebRTC-powered apps that will have your users sharing all manner of data with one another, all in real time. No third-party libraries or heavy downloads are required for you or your users: you'll be writing and strengthening your knowledge of vanilla JavaScript and native browser APIs.You'll learn how to directly connect multiple browsers over the open internet using a signaling channel. You will gain familiarity with a whole set of Web APIs whose features bring WebRTC to life: requesting access to users' cameras and microphones; accessing and manipulating arbitrary user files, right in the browser; and web storage for persisting shared data over the life of a WebRTC call. Like any Web API, WebRTC doesn't enjoy a perfect implementation in any browser. But this book will guide you in writing elegant code to the specification, with backward-compatible fallback code for use in almost all modern browsers.Use WebRTC to build the next generation of web applications that stream media and data in real time, directly from one user to another - all by working in the browser.What You Need:Readers need a text editor, an up-to-date copy of Chrome or Firefox, and a POSIX-style command-line shell. They'll also need to install a little bit of open-source software, especially Node.js. All necessary setup is covered in full in the book's introductory chapter.

Taschenbuch. Zustand: Neu. Neuware - If you thought data structures and algorithms were all just theory, you're missing out on what they can do for your JavaScript code. Learn to use Big O notation to make your code run faster by orders of magnitude. Choose from data structures such as hash tables, trees, and graphs to increase…your code's efficiency exponentially. With simple language and clear diagrams, this book makes this complex topic accessible, no matter your background. Every chapter features practice exercises to give you the hands-on information you need to master data structures and algorithms for your day-to-day work.Algorithms and data structures are much more than abstract concepts. Mastering them enables you to write code that runs faster and more efficiently, which is particularly important for today's web and mobile apps. Take a practical approach to data structures and algorithms, with techniques and real-world scenarios that you can use in your daily production code. The JavaScript edition uses JavaScript exclusively for all code examples, exercises, and solutions.Use Big O notation to measure and articulate the efficiency of your code, and modify your algorithm to make it faster. Find out how your choice of arrays, linked lists, and hash tables can dramatically affect the code you write. Use recursion to solve tricky problems and create algorithms that run exponentially faster than the alternatives. Dig into advanced data structures such as binary trees and graphs to help scale specialized applications such as social networks and mapping software. You'll even encounter a single keyword that can give your code a turbo boost. Practice your new skills with exercises in every chapter, along with detailed solutions.Use these techniques today to make your JavaScript code faster and more scalable.What You Need:Certain code examples take advantage of recently introduced JavaScript features. Therefore, it's important to use a JavaScript environment that supports ECMAScript 6+ or a newer version.
