Building Progressive Web AppsMove over native apps. New progressive web apps have capabilities that will soon make you obsolete. With this hands-on guide, web developers and business execs will learn how - and why - to develop web apps that take advantage of features that have so far been exclusive to native apps. Features that include fast load times, push notifications, offline access, homescreen shortcuts, and an entirely app-like experience.
By leveraging the latest browser APIs, progressive web apps combine all of the benefits of native apps, while avoiding their issues. Throughout the book, author Tal Ater shows you how to improve a simple website for the fictional Gotham Imperial Hotel into a modern progressive web app.
Understand how service workers work, and use them to create sites that launch in an instant, regardless of the user's internet connection; Create full-screen web apps that launch from the phone's homescreen just like native apps; Re-engage users with push notifications, even days after ...
Building Microservices with ASP.NET CoreAt a time when nearly every vertical, regardless of domain, seems to need software running in the cloud to make money, microservices provide the agility and drastically reduced time to market you require. This hands-on guide shows you how to create, test, compile, and deploy microservices, using the ASP.NET Core free and open-source framework. Along the way, you'll pick up good, practical habits for building powerful and robust services.
Building microservices isn't about learning a specific framework or programming language; it's about building applications that thrive in elastically scaling environments that don't have host affinity, and that can start and stop at a moment's notice. This practical book guides you through the process.
Learn test-driven and API-first development concepts; Communicate with other services by creating and consuming backing services such as databases and queues; Build a microservice that depends on an external data source; Learn about event sourcing, ...
Kubernetes: Up and RunningLegend has it that Google deploys over two billion application containers a week. How's that possible? Google revealed the secret through a project called Kubernetes, an open source cluster orchestrator (based on its internal Borg system) that radically simplifies the task of building, deploying, and maintaining scalable distributed systems in the cloud. This practical guide shows you how Kubernetes and container technology can help you achieve new levels of velocity, agility, reliability, and efficiency.
Authors Kelsey Hightower, Brendan Burns, and Joe Beda - who've worked on Kubernetes at Google and other organizatons - explain how this system fits into the lifecycle of a distributed application. You will learn how to use tools and APIs to automate scalable distributed systems, whether it is for online services, machine-learning applications, or a cluster of Raspberry Pi computers.
Explore the distributed system challenges that Kubernetes addresses; Dive into containerized appl ...
Programming LEGO EV3 My BlocksProgram Lego My Blocks to accurately perform navigation functions on competition mats, such as moving forward and backward quickly and precisely, turning, following walls, and following lines. This book features extensive illustrations help to bring each step and concept to life so that you can easily follow along.
You'll start by moving your creations forward and backward accurate distances while maintaining directional accuracy. You'll then build My Blocks to turn left and right at precise angles. After that you're creations will be ready to find, follow, and otherwise use lines on the mat to improve navigation accuracy. Finally, you'll delve into using game board border walls to navigate and advanced topics, such as handoffs at speed and accelerating/decelerating to enable higher speed while maintaining navigation accuracy.
This book addresses EV3 programming in the specific context of FLL competition. With Programming Lego EV3 My Blocks, you will be game-ready to manage the ...

The Art of Capacity Planning, 2nd EditionIn their early days, Twitter, Flickr, Etsy, and many other companies experienced sudden spikes in activity that took their web services down in minutes. Today, determining how much capacity you need for handling traffic surges is still a common frustration of operations engineers and software developers. This hands-on guide provides the knowledge and tools you need to measure, deploy, and manage your web application infrastructure before you experience explosive growth.
In this thoroughly updated edition, authors Arun Kejariwal (MZ) and John Allspaw provide a systematic, robust, and practical approach to capacity planning - rather than theoretical models - based on their own experiences and those of many colleagues in the industry. They address the vast sea change in web operations, especially cloud computing.
Understand issues that arise on heavily trafficked websites or mobile apps; Explore how capacity fits into web/mobile app availability and performance; Use tools for measur ...
Practical Modern JavaScriptTo get the most out of modern JavaScript, you need learn the latest features of its parent specification, ECMAScript 6 (ES6). This book provides a highly practical look at ES6, without getting lost in the specification or its implementation details. Armed with practical examples, author Nicolas Bevacqua shows you new ways to deal with asynchronous flow control, declare objects or functions, and create proxies or unique sets, among many other features.
The first title in Bevacqua's Modular JavaScript series, Practical Modern JavaScript prepares JavaScript and Node.js developers for applied lessons in modular design, testing, and deployment in subsequent books.
This book explains: How JavaScript and its standards development process have evolved; Essential ES6 changes, including arrow functions, destructuring, let and const; Class syntax for declaring object prototypes, and the new Symbol primitive; How to handle flow control with Promises, iterators, generators, and async function ...
Text Mining with RMuch of the data available today is unstructured and text-heavy, making it challenging for analysts to apply their usual data wrangling and visualization tools. With this practical book, you'll explore text-mining techniques with tidytext, a package that authors Julia Silge and David Robinson developed using the tidy principles behind R packages like ggraph and dplyr. You'll learn how tidytext and other tidy tools in R can make text analysis easier and more effective.
The authors demonstrate how treating text as data frames enables you to manipulate, summarize, and visualize characteristics of text. You'll also learn how to integrate natural language processing (NLP) into effective workflows. Practical code examples and data explorations will help you generate real insights from literature, news, and social media.
Learn how to apply the tidy text format to NLP; Use sentiment analysis to mine the emotional content of text; Identify a document's most important terms with frequency ...
