Unique Programming Skills Bundle

Lua is one of the most widely used scripting languages in the world, yet it remains one of the least understood. This book takes you from writing your very first line of Lua code to mastering advanced topics like metaprogramming with metatables, embedding Lua in C applications, and building production-grade systems. Whether you are a game developer scripting behavior in Roblox or LÖVE2D, a web engineer configuring OpenResty, an editor power user customizing Neovim, or simply a programmer curious about the language that powers so much of modern software, this book gives you the deep, practical knowledge you need. Every concept is explained with annotated code examples, version-aware notes covering Lua 5.1 through the latest 5.5 release, and real-world context drawn from the projects and communities that make Lua matter.

Smalltalk is not just a programming language. It is a complete computing environment whose design philosophy where everything is an object, communication via message passing and interactive live development that offers unique power and clarity that continues to influence modern software engineering. This book takes you from zero Smalltalk experience to advanced practitioner level, covering the language's history, its distinctive concepts, practical programming techniques, and modern ecosystem tools. Whether you are a curious developer exploring object-oriented roots or a professional seeking deeper mastery, this book functions as both a structured learning resource and a long-term reference for serious Smalltalk development.

OCaml is one of the most powerful and elegant programming languages available today, yet it remains relatively unknown outside specialized communities. This book takes you on a complete journey from writing your very first OCaml program to deploying production-quality applications. Whether you are a student encountering functional programming for the first time, a professional developer looking to expand your toolkit, or an experienced programmer seeking mastery of one of the most expressive languages in existence, this book provides everything you need. Every concept is explained clearly with practical examples, exercises, and real-world context drawn from OCaml's rich ecosystem and its use at companies like Jane Street, Meta, Bloomberg, and Docker.

This book teaches modern Delphi development from first principles through production-grade architecture. Using RAD Studio 13 Florence as the reference platform, it covers the Object Pascal language, the runtime library, VCL and FireMonkey UI frameworks, FireDAC database programming, REST integration, concurrency, testing, deployment and legacy code modernization. Every concept is explained with complete, compilable examples and practical guidance about when to use each technique, what tradeoffs exist, and which patterns fit real-world Delphi applications best.

This book takes you from complete beginner to expert-level proficiency in Julia, one of the most powerful and elegant programming languages for technical computing. Through clear explanations, comprehensive examples, and real-world projects, you will learn not only how to write Julia code but also why the language is designed the way it is and how to leverage its unique features for maximum performance and productivity. Whether you are a data scientist, researcher, engineer, or software developer, this book gives you everything needed to use Julia confidently in both research and production environments.
