Designing for Human Intelligence in an Artificial Intelligence World: Understanding Human Cognition to Design for Humans
by Rebecca Baker Jerome L. RekartHow we think and react has a direct impact on experience design, but often designers don't understand the "whys" behind their best practices, leaving them at risk for misusing or underutilizing those designs. Similarly, psychologists/neuroscientists don't understand the design decisions that their science is informing and how they might be leveraged further. This book explores how neuroscience and cognitive psychology inform experience design, within the modern context of research and technological advances. With a conversational and playful tone, this book begins by grounding you in research and AI. That foundation then allows you to expand your repertoire through chapters on design-relevant cognitive phenomena such as memory, learning, and perception. By delving into how our brains handle these processes and how our designs can effectively (or ineffectively) leverage them, the book follows a journey that weaves academic learning with practical, real-world applications and examples. With the widespread availability of generative AI tools, understanding the intersection of human cognition and design and how that knowledge can be used to build a bridge between the brain and the software has become even more critical. By understanding the brain and human behavior more completely, designers will be able to effectively use AI as an accelerator for tactical projects and provide the context that is unique to the human ability to understand the "why.&”

Magical Haskell: A Friendly Approach to Modern Functional Programming, Type Theory, and Artificial Intelligence
by Anton AntichDiscover a unique and fun approach to adopting modern typed functions programming patterns. This book uses playful metaphors and examples to help you learn Haskell through imagination, building on math without relying on imperative crutches or technical complexity. You’ll use math to build completely different Typed Functional patterns from the ground up and understand the link between building Mathematics through Types and constructing Haskell as a programming language. Intended for working with various applications, especially AI-powered apps, the book gently builds up to what are normally considered complex and difficult concepts all without needing a PhD to understand them. Illustrative explanations will guide you to tackle monads, using monad transformer stacks to structure real programs, foldable and traversable structures, as well as other Type classes. This book will also help you structure programs efficiently and apply your own abstractions to real-life problem domains. Next, you’ll explore exciting advancements in AI, including building with OpenAI APIs, creating a terminal chatbot, adding web functionality, and enhancing with retrieval-augmented generation. Finally, you’ll delve into AI multi-agents and future directions using Arrows abstraction, reinforcing Haskell’s design. Magical Haskell is a solution for programmers who feel limited by imperative programming languages but are also put off by excessively mathematical approaches. What You Will Learn Grasp a solid math foundation without complex technicalities for Types and Typeclasses. Solve problems via a typed functional approach and understand why it’s superior to what’s available in the imperative language world (“if it compiles, it runs”). Build your own abstractions to efficiently resolve problems in any given domain. Develop AI frameworks in Haskell, including chatbots, web functionality, and retrieval-augmented generation. Who This Book Is For Haskell programmers of all levels and those interested in Type Theory.
Task Programming in C# and .NET: Modern Day Foundation for Asynchronous Programming (Apress Pocket Guides)
by Vaskaran SarcarAt a high level, to understand asynchronous programming, you need to be familiar with task programming, efficient use of the async and await keywords, and a few more important topics. However, task programming is the first major step towards modern-day asynchronous programming. This book tries to simplify the topic with simple examples, Q&A sessions, and exercises The book starts with an introduction to asynchronous programming and covers task creation and execution. Next, you will learn how to work with continuing and nested tasks. Next, it demonstrates exception handling with different scenarios. Towards the end, you will understand how to manage task cancellations through examples and case studies. After reading this book, you can write efficient codes for multithreaded, asynchronous, and parallel development in C#. What You Will Learn: Dig deep into task programming which is an essential part of the concurrent and multithreaded developments. Learn modern-day C# features that are foundations of asynchronous programming How the advanced features in C# such as delegates, lambdas, generics, etc. can be used in concurrency Who This Book is For: C# and .NET developers
