Visionary designer and technologist John Maeda defines the fundamental laws of how computers think, and why you should care even if you aren't a programmer. "Maeda is to design what Warren Buffett is to finance." --Wired John Maeda is one of the world's preeminent interdisciplinary thinkers on technology and design. In How to Speak Machine, he offers a set of simple laws that govern not only the computers of today, but the unimaginable machines of the future. Technology is already more powerful than we can comprehend, and getting more powerful at an exponential pace. Once set in motion, algorithms never tire. And when a program's size, speed, and tirelessness combine with its ability to learn and transform itself, the outcome can be unpredictable and dangerous. Take the seemingly instant transformation of Microsoft's chatbot Tay into a hate-spewing racist, or how crime-predicting algorithms reinforce racial bias. How to Speak Machine provides a coherent framework for today's product designers, business leaders, and policymakers to grasp this brave new world. Drawing on his wide-ranging experience from engineering to computer science to design, Maeda shows how businesses and individuals can identify opportunities afforded by technology to make world-changing and inclusive products--while avoiding the pitfalls inherent to the medium.
Lively essays exploring topics from digital logic and machine language to artificial intelligence and searching the World Wide Web.
Starting with the client-server model, this book attempts to integrate disparate topics of state-of-the-art telecommunications principles. Typically, data communications and telecommunications have been separated, but are linked here. Timing of computers and the problems of jitter are brought to bear, as is multiplexing and circuit- and packet-switching. Protocol architecture is discussed from a point of functions that then lend themselves to the “layering” concepts. Business and regulation issues, pertaining to the issues discussed, are included. The book integrates these concepts by illustrating how these disparate issues form the underpinnings of the World Wide Web.
Discusses how to set up defenses against hackers and online con artists, encryption methods, anonymizer software, spam, viruses, identity theft, firewalls, and ways to safeguard online purchases.
The national information infrastructure (NII) holds the promise of connecting people of all ages and descriptionsâ€"bringing them opportunities to interact with businesses, government agencies, entertainment sources, and social networks. Whether the NII fulfills this promise for everyone depends largely on interfacesâ€"technologies by which people communicate with the computing systems of the NII. More Than Screen Deep addresses how to ensure NII access for every citizen, regardless of age, physical ability, race/ethnicity, education, ability, cognitive style, or economic level. This thoughtful document explores current issues and prioritizes research directions in creating interface technologies that accommodate every citizen's needs. The committee provides an overview of NII users, tasks, and environments and identifies the desired characteristics in every-citizen interfaces, from power and efficiency to an element of fun. The book explores: Technological advances that allow a person to communicate with a computer system. Methods for designing, evaluating, and improving interfaces to increase their ultimate utility to all people. Theories of communication and collaboration as they affect person-computer interactions and person-person interactions through the NII. Development of agents: intelligent computer systems that "understand" the user's needs and find the solutions. Offering data, examples, and expert commentary, More Than Screen Deep charts a path toward enabling the broadest-possible spectrum of citizens to interact easily and effectively with the NII. This volume will be important to policymakers, information system designers and engineers, human factors professionals, and advocates for special populations.

This newly revised second edition looks at ways in which teachers can develop children's abilities in speaking and listening, as required by the National Curriculum. The authors discuss the links between language and learning; offer case studies and suggestions for classroom practice; and provide stimulating activities to help pupils to become more articulate, coherent and effective in standard English. The book is a suitable text for students taking primary initial teacher training courses. It will also be welcomed as a practical handbook for primary teachers.
With its flexibility for programming both small and large projects, Scala is an ideal language for teaching beginning programming. Yet there are no textbooks on Scala currently available for the CS1/CS2 levels. Introduction to the Art of Programming Using Scala presents many concepts from CS1 and CS2 using a modern, JVM-based language that works we
