This book will give you an insight into controlling your applications with gestures and head motion and readying them for the web. Packed with real-world tasks, it begins with a walkthrough of the basic concepts of Computer Vision that the JavaScript world offers us, and you’ll implement various powerful algorithms in your own online application. Then, we move on to a comprehensive analysis of JavaScript functions and their applications. Furthermore, the book will show you how to implement filters and image segmentation, and use tracking.js and jsfeat libraries to convert your browser into Photoshop. Subjects such as object and custom detection, feature extraction, and object matching are covered to help you find an object in a photo. You will see how a complex object such as a face can be recognized by a browser as you move toward the end of the book. Finally, you will focus on algorithms to create a human interface. By the end of this book, you will be familiarized with the application of complex Computer Vision algorithms to develop your own applications, without spending much time learning sophisticated theory.

Generative AI is powerful, yet often unpredictable. This guide shows you how to turn that unpredictability into reliability by thinking beyond prompts and approaching AI like an architect. At its core is the Context Engine, a glass-box, multi-agent system you’ll learn to design and apply across real-world scenarios.Written by an AI guru and author of various cutting-edge AI books, this book takes you on a hands-on journey from the foundations of context design to building a fully operational Context Engine. Instead of relying on brittle prompts that give only simple instructions, you’ll begin with semantic blueprints that map goals and roles with precision, then orchestrate specialized agents using the Model Context Protocol. As the engine evolves, you’ll integrate memory and high-fidelity retrieval with citations, implement safeguards against data poisoning and prompt injection, and enforce moderation to keep outputs aligned with policy. You’ll also harden the system into a resilient architecture, then see it pivot across domains, from legal compliance to strategic marketing, proving its domain independence.By the end of this book, you’ll be equipped with the skills to engineer an adaptable, verifiable architecture you can repurpose across domains and deploy with confidence.*Email sign-up and proof of purchase required

Czysta architektura. Struktura i design oprogramowania. Przewodnik dla profesjonalistów

Pierwsze linie kodu powstawały pół wieku temu. Komputery, na które tworzono te programy, w bardzo niewielkim stopniu przypominały współczesne maszyny. Niezależnie od upływu lat, postępu technologii i powstawania wymyślnych narzędzi, języków programowania czy frameworków pewne zasady tworzenia kodu pozostają niezmienne. Są takie same jak w czasie, gdy Alan Turing pisał pierwszy kod maszynowy w 1946 roku. Respektowanie tych zasad to warunek, że uzyska się oprogramowanie o czystej architekturze, czyli poprawne strukturalnie, łatwe w utrzymaniu i rozwijaniu, a przede wszystkim działające zgodnie z oczekiwaniami. W tej książce w sposób jasny i bardzo interesujący przedstawiono uniwersalne zasady architektury oprogramowania wraz z szeregiem wskazówek dotyczących stosowania tych reguł w praktyce. Wyczerpująco zaprezentowano tu dostępne rozwiązania i wyjaśniono, dlaczego są one tak istotne dla sukcesu przedsięwzięcia. Publikacja jest wypełniona bardzo praktycznymi rozwiązaniami problemów, z którymi musi się mierzyć wielu programistów. Szczególnie cenne są uwagi dotyczące zapobiegania częstemu problemowi, jakim jest stopniowa utrata jakości kodu w miarę postępu projektu. Ta książka obowiązkowo powinna się znaleźć w podręcznej biblioteczce każdego architekta oprogramowania, analityka systemowego, projektanta i menedżera! Z książki dowiesz się: Do czego muszą dążyć architekci oprogramowania i w jaki sposób mogą osiągać te cele Jak brzmią najważniejsze zasady projektowania oprogramowania związane z adresowaniem funkcji, separacją komponentów i zarządzaniem danymi W jaki sposób paradygmaty oprogramowania wzmagają dyscyplinę pracy Co podczas tworzenia oprogramowania jest więcej, a co jest mniej ważne W jaki sposób implementować optymalne struktury dla sieci WWW, baz danych, konsoli i aplikacji osadzonych Czysta architektura - doskonały kod!

D is a programming language with C-like syntax and static typing. The vibe.d framework builds on powerful D concepts like template meta-programming and compile-time function execution to provide an easy-to-use environment for web applications. The combination of a feature-rich web programming framework with a language compiling to native code solves two common issues in web development today: it accelerates your development and it results in fast, native web applications. Learning the vibe.d framework before you start your application will help you to choose the right features to reach your goal.This book guides you through all aspects of web development with D and the vibe.d framework.Covering the popular operating systems today, this guide starts with the setup of your development system. From the first Hello World-style application you will move on to building static web pages with templates. The concise treatment of web forms will give you all the details about form handling and web security. Using the abstractions of the web framework you will learn how to easily validate user input. Next, you will add database access to your application, providing persistent storage for your data. Building on this foundation, you will expose your component and integrate other components via REST. Learning about the internals of vibe.d you will be able to use low-level techniques such as raw TCP access. The vibe.d concepts can also be used for GUI clients, which is the next topic that you will learn. vibe.d is supported by an active community, which adds new functionality. This comprehensive guide concludes with an overview of the most useful vibe.d extensions and where to find them. It also shows you how to integrate these extensions in your application.The concepts are always illustrated with source code, giving you an insight into how to apply them in your application.
