Object-Oriented Programming

Modern Fortran is still powering some of the world's toughest scientific problems. This practical guide takes you from the basics to high-performance computing, covering modern language features, parallel programming, numerical reliability and optimization. Learn to write scientific software that is clean, fast and built to last.

In this book, you'll see that the book is designed with one main idea. It aims to give you the skills, confidence and understanding you need to build and deliver real Backend systems. Each chapter is designed to teach you everything you need to know to get hands-on with writing, configuring, deploying and troubleshooting your own projects. Right at the start, we got stuck into designing APIs and building backend systems. We didn't just stick to the basics, though. We went beyond that pretty quickly and started using modern protocols like gRPC and the key contract-first methods that are now the norm for scalable backend systems.

Pascal is more than a piece of programming history. Discover a language built for clarity, precision and disciplined thinking, then follow its evolution into modern Object Pascal. From your first program to generics, memory management and professional design patterns, this practical guide takes you from foundations to mastery.

Master modern Delphi from the ground up and build software that’s ready for the real world. From Object Pascal and VCL to FireMonkey, FireDAC, REST, concurrency and testing, this hands-on guide shows you how to write clean, maintainable applications with RAD Studio 13 Florence, backed by practical examples and proven techniques.

Discover Smalltalk, the language that shaped object-oriented programming. From its core philosophy to hands-on techniques and modern tools, this guide takes you from your first message to confident development in a live, interactive environment. Learn why Smalltalk still matters and how its ideas can change the way you think about code.

Elegant Design Principles distils decades of design wisdom into 95 actionable principles spanning core OO, SOLID/GRASP, package design, reliability and a forward‑looking AI‑first approach. Explore the Design Pyramid to understand how quality attributes, smells and principles interconnect; learn to manage complexity through high cohesion, low coupling and clear abstractions; and adopt modern practices like test‑driven development and semantic modularity. From novices seeking a roadmap to experts embracing AI‑assisted workflows, this book equips you to create systems that are robust, maintainable and elegant—today and in the AI‑driven future.

Modern Java is more than a collection of new language features—it is a shift from implementing mechanics to expressing intent. Learn how records, sealed types, pattern matching, streams, modules, virtual threads, and other modern capabilities help you build Java software that is clearer, safer, and easier to evolve.

Forget IShape — it's time to build software that actually does something. OrderFlow takes ten classic Gang of Four design patterns and weaves them into a single, fully functional food delivery platform built with C# and .NET 10. Clone the repository, step through the production-grade code, and finally master not just how to write patterns, but when to use them (and when to keep it simple).

Master Swift from the ground up and learn how to write clean, modern code with confidence. From core language fundamentals to concurrency, generics, protocols and production-ready architecture, this practical guide covers the Swift features that matter in 2026 with clear explanations and useful examples.

Learn software testing the way it’s actually done: by doing it. The Test Analyst Field Workbook guides you step-by-step through every part of a test analyst’s job — from reading requirements and designing test cases, to logging defects, running regression cycles, and helping decide when software is ready to release. With real examples, reusable templates, and dozens of practice exercises, this book turns theory into practical skill you can use from day one.

Java 21 and Java 25 LTS, feature by feature. Records, virtual threads, pattern matching, structured concurrency, FFM, JFR, gatherers. One runnable Maven module per chapter. JDK-only, no framework noise. For engineers who shipped Java 11 and now have to update.

A practical backend interview reference covering modern Python and Django development (438 manuscript pages).

Bridge the gap from C# basics to professional, high-performance AI systems. Master advanced polymorphism, Generics, and functional programming patterns. Learn to architect resilient AI pipelines and manage unmanaged GPU memory. Design and build an enterprise-grade, plugin-based chatbot application from scratch.

140 Tips for Clean Code distills 140 practical, field-tested tips for writing clean, readable, and maintainable code. Each tip is concise, actionable, and grounded in real-world development challenges. No theory for theory’s sake. Whether you are refining a legacy system or starting from scratch, these insights will help you reduce complexity, prevent defects, and make your code a pleasure to work with. Clean code is not an aesthetic choice; it is a professional advantage.
