You can’t just find a pattern and copy it into your program, the way you can with off-the-shelf functions or libraries. The pattern is not a specific piece of code, but a general concept for solving a particular problem. They are like pre-made blueprints that you can customize to solve a recurring design problem in your code.The book Dive Into Design Patterns illustrates 22 classic design patterns and 8 design principles that these patterns are based on.- Every chapter starts from a discussion of a real life software design problem which is then progressively solved by applying one of the patterns.- Then goes a detailed review of the pattern’s structure and its variations, followed by a code example.- Then the books shows various applications of the pattern and teaches how to implement the pattern step by step, even in an existing program.- Each chapter concludes with a discussion of pros and cons of the pattern and its relations, similarities and differences with other patterns.

    We're picking up right where we left off and write a compiler and a virtual machine for Monkey. Runnable and tested code front and center, built from the ground up, step by step — just like before. But this time, we're going to define bytecode, compile Monkey and execute it in our very own virtual machine. It's the next step in Monkey's evolution. It's the sequel to … a programming language Writing A Compiler In Go is the sequel to Writing An Interpreter In Go. It starts right where the first one stopped, with a fully-working, fully-tested Monkey interpreter in hand, connecting both books seamlessly, ready to build a compiler and a virtual machine for Monkey. In this book, we use the codebase (included in the book!) from the first part and extend it. We take the lexer, the parser, the AST, the REPL and the object system and use them to build a new, faster implementation of Monkey, right next to the tree-walking evaluator we built in the first book. The approach is unchanged, too. Working, tested code is the focus, we build everything from scratch, do baby steps, write tests firsts, use no 3rd-party-libraries and see and understand how all the pieces fit together. It's a continuation in prose and in code. Do you need to read the first part before this one? If you're okay with treating the code from the first book as black box, then no. But that's not what these books are about; they're about opening up black boxes, looking inside and shining a light. You'll have the best understanding of where we're going in this book, if you know where we started. Learn how to write a compiler and a virtual machine Our main goal in in this book is to evolve Monkey. We change its architecture and turn it into a bytecode compiler and virtual machine. We'll take the lexer, the parser, the AST and the object system we wrote in the first book and use them to build our own Monkey compiler and virtual machine … from scratch! We'll build them side-by-side so that we'll always have a running system we can steadily evolve. What we end up with is not only much closer to the programming languages we use every day, giving us a better understanding of how they work, but also 3x faster. And that's without explicitly aiming for performance. Here's what we'll do: - We define our own bytecode instructions, specifying their operands and their encoding. Along the way, we also build a mini-disassembler for them. - We write a compiler that takes in a Monkey AST and turns it into bytecode by emitting instructions - At the same time we build a stack-based virtual machine that executes the bytecode in its main loop We'll learn a lot about computers, how they work, what machine code and opcodes are, what the stack is and how to work with stack pointers and frame pointers, what it means to define a calling convention, and much more. We also - build a symbol table and a constant pool - do stack arithmetic - generate jump instructions - build frames into our VM to execute functions with local bindings and arguments! - add built-in functions to the VM - get real closures working in the virtual machine and learn why closure-compilation is so tricky

Do all of this in whichever language and environment you prefer, and do it entirely test-first, so you know it’s correct. Recharge yourself with this project’s immense potential for personal exploration, experimentation, and discovery.About this TitleThe renderer is a ray tracer, which means it simulates the physics of light by tracing the path of light rays around your scene. Each exciting chapter presents a bite-sized piece of the puzzle, building on earlier chapters and setting the stage for later ones. Requirements are given language-agnostically; it’s up to you to translate them into tests and code using whatever language you prefer. When the project is complete, you’ll look back and realize you’ve built an entire system test-first!There’s no research necessary—all the necessary formulas and algorithms are presented and illustrated right here. Dive into intriguing topics from fundamental concepts such as vectors and matrices; to the algorithms that simulate the intersection of light rays with spheres, planes, cubes, cylinders, and triangles; to geometric patterns such as checkers and rings. Lighting and shading effects, such as shadows and reflections, make your scenes come to life, and constructive solid geometry (CSG) enables you to combine your graphics primitives in simple ways to produce complex shapes.Play and experiment as you discover the fun of writing a ray tracer. Accept the challenge today!What You NeedAside from a computer, operating system, and programming environment, you’ll need a way to display PPM image files.

    Dependent types are a first-class part of a language, and are much more powerful than other kinds of types; using just one language for types and programs allows program descriptions to be as powerful as the programs they describe. The Little Typer explains dependent types, beginning with a very small language that looks very much like Scheme and extending it to cover both programming with dependent types and using dependent types for mathematical reasoning. Readers should be familiar with the basics of a Lisp-like programming language, as presented in the first four chapters of The Little Schemer.The first five chapters of The Little Typer provide the needed tools to understand dependent types; the remaining chapters use these tools to build a bridge between mathematics and programming. Readers will learn that tools they know from programming—pairs, lists, functions, and recursion—can also capture patterns of reasoning. The Little Typer does not attempt to teach either practical programming skills or a fully rigorous approach to types. Instead, it demonstrates the most beautiful aspects as simply as possible, one step at a time.

    What is the philosophical and spiritual significance of this dependence on electronic technology, both for our relationship to nature and for the future of humanity? And, what processes in human perception and awareness have produced the situation we find ourselves in?As Jeremy Naydler elucidates in this penetrating study, we cannot understand the emergence of the computer without seeing it within the wider context of the evolution of human consciousness, which has taken place over millennia. Modern consciousness, he shows, has evolved in conjunction with the development of machines and under their intensifying shadow.The computer was the product of a long historical development, culminating in the scientific revolution of the 17th century. It was during this period that the first mechanical calculators were invented and the project to create more complex `thinking machines' began in earnest. But the seeds were sown many hundreds of years earlier, deep in antiquity. Naydler paints a vast panorama depicting human development and the emergence of electronic technology. His painstaking research illuminates an urgent question that concerns every living person today: What does it mean to be human and what, if anything, distinguishes us from machines?

    But implementing a microservices architecture and selecting the necessary technologies are difficult challenges. This book shows microservices recipes that architects can customize and combine into a microservices menu. In this way, the implementation of microservices can be individually adapted to the requirements of the project. Eberhard Wolff introduces microservices, self-contained systems, micro- and macro-architecture and the migration to microservices. The second part shows the microservices recipes: Basic technologies such as Docker or PaaS, frontend integration with links, JavaScript or ESI (Edge Side Includes). This is followed by asynchronous microservices with Apache Kafka or REST / Atom. In the synchronous approaches, the book discusses REST with the Netflix stack, Consul, PaaS with Cloud Foundry, and Kubernetes. Finally, operations is discussed: Log Analysis with Elasticsearch and Kibana, Monitoring with Prometheus, and tracing with Zipkin. For each recipe there are suggestions for variations and combinations. Readers can experience all technologies hands-on with a demo project on GitHub. The outlook picks up on the operation of microservices and also shows how the reader can start with microservices in concrete terms. The book provides the technical tools to implement a microservices architecture. Demo projects and suggestions for self-study will complete the book.

     In compact chapters, concentrating on the essentials, you'll get to know Kotlin within a few afternoons or some subway rides, and you'll soon be able to use it to write your own programs and apps. As the title suggests, "Kotlin Compact" is not explicitly an all-encompassing work on Kotlin. Rather, it focuses on the necessary foundations and best features Kotlin has to offer, and which are most valuable when getting started with Kotlin development. About the author My name is Thorsten Schleinzer, I am a graduate in Media Information Technology and have been a professional software developer and architect for over 20 years. For a long time I have been working intensively with different programming languages. I started with BASIC, got to C/C++ via Pascal/Delphi & Assembler and finally arrived at Java. Although I've been developing with Java since its version 1.2, I've been working with or am still using several other languages: C#, PHP, JavaScript/TypeScript, Ruby, Dart, Lua, Scala, and a few more. But it was only with Kotlin that a new language was able to fully delight me and convince me of a change.

    Whether you're getting to grips with C# for the first time or working to deepen your understanding, you'll find this book to be a clear and refreshing take on each aspect of the language.Figures are of prime importance in this book.
