Getting to Know Mobile GIS empowers readers to creatively use Mobile GIS and drive innovation in this fast-advancing field."Mobile-first" and the "post-PC era" aren't just buzzwords; they represent today's reality. Within the GIS industry, the mobile internet and Mobile GIS have profoundly transformed how we acquire, visualize, analyze, and disseminate geospatial information. With its ubiquitous use and location-aware capabilities, the mobile platform is an essential part of enterprise GIS across industries, making Mobile GIS crucial to the business operations and future success of wide-ranging organizations.Getting to Know Mobile GIS helps GIS professionals and GIS students grasp the opportunities presented by Mobile GIS. It provides principles and detailed tutorials to teach today's cutting-edge Mobile GIS technologies. Using a no-code, low-code approach, it makes Mobile GIS easy and fun to learn. Readers can immediately become productive in creating enterprise GIS solutions, ranging from online and offline spatial data visualization, data collection, location sharing, and workforce coordination to integration with enterprise workflows.Pinde Fu leads the ArcGIS Platform Engineering team at Esri Professional Services and teaches at universities, including Harvard University Extension School. His specialties include Web and Mobile GIS technologies and applications in various industries. Several of his projects have won special achievement awards.

Content distribution, i.e., distributing digital content from one node to another node or multiple nodes, is the most fundamental function of the Internet. Since Amazon's launch of EC2 in 2006 and Apple's release of the iPhone in 2007, Internet content distribution has shown a strong trend toward polarization. On the one hand, considerable investments have been made in creating heavyweight, integrated data centers ("heavy-cloud") all over the world, in order to achieve economies of scale and high flexibility/efficiency of content distribution. On the other hand, end-user devices ("light-end") have become increasingly lightweight, mobile and heterogeneous, creating new demands concerning traffic usage, energy consumption, bandwidth, latency, reliability, and/or the security of content distribution. Based on comprehensive real-world measurements at scale, we observe that existing content distribution techniques often perform poorly under the abovementioned new circumstances.Motivated by the trend of "heavy-cloud vs. light-end," this book is dedicated to uncovering the root causes of today's mobile networking problems and designing innovative cloud-based solutions to practically address such problems. Our work has produced not only academic papers published in prestigious conference proceedings like SIGCOMM, NSDI, MobiCom and MobiSys, but also concrete effects on industrial systems such as Xiaomi Mobile, MIUI OS, Tencent App Store, Baidu PhoneGuard, and WiFi.com. A series of practical takeaways and easy-to-follow testimonials are provided to researchers and practitioners working in mobile networking and cloud computing. In addition, we have released as much code and data used in our research as possible to benefit the community.

From the basics of scripting to techniques for interactivity, AI and behavior, animation, narrative, and networking, this flexible, mind-bogglingly popular engine is useful for anything that needs visuals and real-time simulation. With this thoroughly updated problem-solving cookbook, beginner and intermediate Unity developers will learn about the Unity engine through brief recipes that teach specific features of the software and scripting systems. You'll apply a collection of snippets of code to address common scenarios such as properly keeping score, accepting input, and sharing state over the network." --

Getting to Know Web GIS, a workbook with detailed, step-by-step exercises, teaches readers how to share resources online and build web GIS applications easily and quickly. It covers Esri's suite of web GIS technologies including ArcGIS Online, ArcGIS for Server, web app templates, WebApp Builder, API for JavaScript, mobile GIS apps, mobile SDKs, CityEngine, and 3D web maps. Holistic Approach: Unlike books that focus on individual products, this book teaches web GIS technologies as a holistic platform. Each chapter completes an application project using multiple products from server side to browser/client side. Easy to Apply: You don't have to be a developer to build web apps. This book facilitates immediate productivity. It teaches how to build engaging web apps without a single line of programming. The two chapters involving programming are easy to follow and don't require a strong programing background. Each of the 10 chapters in this book has a conceptual discussion section that gives readers the big picture and the principles, a system requirements section that helps instructors to prepare for the lab setup, a detailed tutorial section with abundant screenshots that confirm progress along the way, a Q/A section to answer common questions, an assignment section for readers to practice what they have just learned, and a robust reference section. This book is the result of the author's extensive working experience at Esri and teaching experience at Harvard University Extension and other universities. It is a practical manual for classroom lab work and on the job training for GIS students, instructors, GIS analysts, managers, web developers, and a broad range of GIS professionals.

Build production-grade web apps from scratch ¿ without using frameworks ¿ with Kotlin on the Java platform. Yoüll learn how to use and compose libraries, how to choose between different libraries, and the benefits of explicit and straight-forward code, vs. the implicit magic, conventions, and inversion of control you often see in frameworks.The book teaches the Kotlin language by building production-ready Kotlin code. Yoüll gain a deep understanding of the idiomatic use of the Kotlin language along with knowledge of how to apply Kotlin in production-grade web apps. The book also bridges the gap between building from scratch and using existing frameworks. For example, yoüll learn how to integrate Spring Security-based authentication in web apps written from scratch, so you can leverage existing tooling in your organization without having to take on the entire Spring framework. The first section of the book sets up thebase structure of your web app, such as routing, configuration files, and database migrations. The remaining chapters are broken into individual aspects of building production-ready web apps. Appendices at the end of the book explain how to use different libraries than the ones chosen in the main chapters, so you'll learn how to decouple your code from specific libraries, and choose between many different libraries to get the job done in your own web apps.What You Will LearnCompose libraries and manage boilerplate code using idiomatic and powerful KotlinManage and query SQL databases without ORMs and mapping layersWrite resilient and change-proof tests in support of test-driven development practicesCreate traditional, HTML-based web apps, APIs for JavaScript-based single-page web apps and native mobile appsManage parallelism and external service calls using Kotlin co-routinesDeploy to production using embedded servers, WAR files, and serverless approachesBridge the gap between custom-built apps and enterprise, using Spring Context and Spring SecurityWho This Book Is ForThe expert developer who is ready to take full control of the tech stack, and use the Kotlin language, type system, and standard library, to ship production-ready web apps. Readers should have prior programming experience. Experience with Java or another JVM language is helpful.
