Eloquent Images: Word and Image in the Age of New Media
by Mary E. Hocks Michelle R. KendrickThe emergence of New Media has stimulated debate about the power of the visual to dethrone the cultural prominence of textuality and print. Some scholars celebrate the proliferation of digital images, arguing that it suggests a return to a pictorial age when knowledge was communicated through images as well as through words. Others argue that the inherent conflict between texts and images creates a battleground between the feminized, seductive power of images and the masculine rationality of the printed word. Eloquent Imagessuggests that these debates misunderstand the dynamic interplay that has always existed between word and image. Arguing that the complex relationship between text and image in New Media does not represent a radical rupture from the past, the book examines rhetorical and cultural uses of word and image both historically and currently. It shows that complex, interpenetrating relationships between verbal and visual communication systems were already evident in hieroglyphic writing and in ancient rhetoric and persist in the work of classical rhetoricians, in cultural studies of technology, even in the binary code distinctions of digital environments. The essays blend theory, critique, and design practice to explore the often contradictory relations of word and image. All of them call for theoretically grounded approaches to hypermedia design.
Internet Literature in China (Global Chinese Culture)
by Michel HockxSince the 1990s, Chinese literary enthusiasts have explored new spaces for creative expression online, giving rise to a modern genre that has transformed Chinese culture and society. Ranging from the self-consciously avant-garde to the pornographic, web-based writing has introduced innovative forms, themes, and practices into Chinese literature and its aesthetic traditions. Conducting the first comprehensive survey in English of this phenomenon, Michel Hockx describes in detail the types of Chinese literature taking shape right now online and their novel aesthetic, political, and ideological challenges. Offering a unique portal into postsocialist Chinese culture, he presents a complex portrait of internet culture and control in China that avoids one-dimensional representations of oppression. The Chinese government still strictly regulates the publishing world, yet it is growing increasingly tolerant of internet literature and its publishing practices while still drawing a clear yet ever-shifting ideological bottom line. Hockx interviews online authors, publishers, and censors, capturing the convergence of mass media, creativity, censorship, and free speech that is upending traditional hierarchies and conventions within China—and across Asia.

IoT Development for ESP32 and ESP8266 with JavaScript: A Practical Guide to XS and the Moddable SDK
by Peter Hoddie Lizzie PraderThis book introduces a new approach to embedded development, grounded in modern, industry-standard JavaScript. Using the same language that powers web browsers and Node.js, the Moddable SDK empowers IoT developers to apply many of the same tools and techniques used to build sophisticated websites and mobile apps. The Moddable SDK enables you to unlock the full potential of inexpensive microcontrollers like the ESP32 and ESP8266. Coding for these microcontrollers in C or C++ with the ESP-IDF and Arduino SDKs works for building basic products but doesn't scale to handle the increasingly complex IoT products that customers expect. The Moddable SDK adds the lightweight XS JavaScript engine to those traditional environments, accelerating development with JavaScript while keeping the performance benefits of a native SDK. Building user interfaces and communicating over the network are two areas where JavaScript really shines. IoT Development for ESP32 and ESP8266 with JavaScript shows you how to build responsive touch screen user interfaces using the Piu framework. You'll learn how easy it is to securely send and receive JSON data over Wi-Fi with elegant JavaScript APIs for common IoT protocols, including HTTP/HTTPS, WebSocket, MQTT, and mDNS. You'll also learn how to integrate common sensors and actuators, Bluetooth Low Energy (BLE), file systems, and more into your projects, and you'll see firsthand how JavaScript makes it easier to combine these diverse technologies. If you're an embedded C or C++ developer who has never worked in JavaScript, don't worry. This book includes an introduction to the JavaScript language just for embedded developers experienced with C or C++. What You'll Learn Building, installing, and debugging JavaScript projects on the ESP32 and ESP8266 Using modern JavaScript for all aspects of embedded development with the Moddable SDK Developing IoT products with animated user interfaces, touch input, networking, BLE, sensors, actuators, and more Who This Book Is For Professional embedded developers who want the speed, flexibility, and power of web development in their embedded software work Makers who want a faster, easier way to build their hobby projects Web developers working in JavaScript who want to extend their skills to hardware products
