Taschenbuch. Zustand: Neu. Neuware - Deepen your Haskell knowledge, sharpen your functional programming skills, and just have fun with 25 functional programming puzzles to tie your brain in knots.Challenge and exercise your functional programming knowledge by tackling these 20 fun, funky, and functional puzzles on Haskell programming topics such as lazy evaluation, Haskell syntax, type classes, and the type system. Gain new insight into why Haskell is the way it is. Build mind-bending self-referential and circular data structures, unpick the seams of reality with unsafePerformIO, build enhanced DSLs with QualifiedDo, and refactor without fear of the dreaded monomorphism restriction. Review or get introduced to Haskell's common quirks such as the unary minus and pattern guards while mastering newer language features up to GHC 9.12, including linear arrows and Or Patterns.Employ powerful techniques and recognize common pitfalls as you solve fiendish puzzles across five different topic areas.Don't sleep on the lazy evaluation puzzles: they'll challenge you to predict the behavior of programs that rely on laziness in unexpected ways. Think syntax and language extensions puzzles should be easy Think again as you deal with the perversity of the unary minus operator, or puzzles based on new extensions like QualifiedDo. Prepare to be perplexed with Type Class puzzles on ad-hoc polymorphism, deriving strategies, and record fields. Want more Try mixing classic ambiguous type puzzles with advanced new features like linear types.After trying your hand at each puzzle, read through the solution to get more insight into key Haskell features, and use the references to build a reading list to dive deeper into new areas of the language.…

Taschenbuch. Zustand: Neu. Neuware - Writing code has never been a problem; getting that code to work is.New code becomes cheaper every day, but maintenance does not. Bugs are faster, subtler, and harder to catch, and dealing with them is increasingly difficult. This book will make it easier, showing you both useful (and underused) features of your browser's developer console and also ways of writing your code that makes it easier to test (and less likely to need debugging in the first place).In just one week you'll master debugging skills that will save you hours every day.Read stack traces as if they were a story, wrap risky code in bulletproof guardrails, and triage issues so that critical ones always get fixed first. Master root-cause analysis, design gracefully failing systems, trace data through tangled chains of callbacks and promises, and make resolving future problems easier for everyone with smart error monitoring. Surprise yourself by the power of familiar Chrome developer tools that have always been readily available to you.Starting from a foundation of process methodologies and software design principles, you'll continue on through practical techniques like logging and interactive debugging before arriving at monitoring and debuggability. In the end, you'll have the knowledge you were missing and the skills you need to help you raise the quality bar and focus on what truly matters most: building exceptional web applications.Happy debugging!What You NeedA computer with a Chromium-based browser such as Chrome, Vivaldi, or Brave, and an IDE such as WebStorm or VSCode. Along the way, you'll be installing command-line tools, so be sure you have permission to do so. …

Taschenbuch. Zustand: Neu. Neuware - Quickly turn complex problems into simple, working solutions using functional programming, safe concurrency, and the expressive tools of Clojure.Struggling with unnecessary complexity, unmanaged state, and brittle data that's hard to change Clojure combines the expressiveness of Lisp with the stability and performance of Java into a practical toolkit for creating simple, extensible applications. With immutable data structures, functional programming, and safe concurrency, Clojure makes it easier to write robust, reusable code. This definitive guide, written by members of the Clojure core team, introduces the language's essentials and then shows how to put everything together in real applications. This edition adds practical coverage of project tooling and interactive development and fresh examples of the latest Clojure features.Build cleaner, more reliable software that can respond to changing requirements over time. Combine Clojure's tools for maximum effectiveness as you work with immutable data, functional programming, and safe concurrency to write programs that solve real-world problems.Start by getting comfortable with Clojure's concise syntax and its interactive REPL, then quickly move into building with immutable collections and the powerful sequence abstraction. Gain practical fluency with functional techniques such as higher-order functions, recursion, partial application, and memoization. Beyond the basics, learn to manage state with Clojure's reference types, build open and extensible systems using protocols and multimethods, and unlock the power of macros for creating your own language features. Seamless Java interop lets you tap into the vast Java ecosystem without sacrificing clarity or safety.This edition adds two new chapters on project tooling and interactive development, guiding you through modern workflows with tests, builds, editors, and the REPL at the center of your process. Learn how to set up projects, manage dependencies, and work productively in Clojure's unique interactive style. When you're finished, you'll be able to think in Clojure: express solutions with clarity, leverage concurrency safely, and build real-world applications that are simpler and more maintainable than you thought possible.What You Need- Java 8 or newer- Clojure 1.12 or newer.…

Taschenbuch. Zustand: Neu. Neuware - Build robust LLM-powered apps, chatbots, and agents while mastering AI engineering principles that will help you outlast the tools and the hype.Want to build an LLM-powered app but don't know where to begin With this step-by-step guide, you can master the underlying principles of AI engineering by building an LLM-powered app from the ground up. Tame unpredictable models with prompt and context engineering. Use evals to keep them on track. Give chatbots the knowledge to answer anything a user wants to know. Equip agents with the tools and smarts to actually get the job done. By the end, you'll have the intuition and the confidence to build on top of LLMs in the real world.Fragmented documentation, obsolete tutorials, and frameworks that deliver a prototype but flop in production can make AI engineering feel overwhelming. But it doesn't have to be that way. With real-world code and step-by-step instructions as your guide, you can learn to build robust LLM-powered apps from the ground up while mastering both the howand why of the most crucial underlying concepts.Harness context engineering and retrieval systems to create AI assistants that understand your proprietary data. Create chatbots that answer organization-specific questions and help solve users' issues. Design agents that conduct research, make decisions, and take action in the real world. Level up your prompt engineering and get an LLM to do your bidding---not its own. Use automated evals to keep constant tabs on your app's quality while setting up guardrails to protect your users and organization. And implement observability systems that make it easy to debug your app when things do go wrong.With a systematic approach grounded in the core principles of building AI apps for real users, you'll easily evolve and adapt even as the hype and tools come and go.…
