Visual Studio 2022 is the complete and ideal integrated development environment (IDE) for creating large, complex, and scalable applications. It is one of the most complete tools available for development, especially with Microsoft technologies.This book will teach you how to take advantage of the tools available with this IDE to write clean code faster. You’ll begin by learning how to set up and start Visual Studio 2022 and how to use all the tools provided by this IDE. You will then explore key combinations, tips, and additional utilities that can help you to code faster and review your code constantly. Next, you will see how to compile, debug, and inspect your project to analyze its current behavior using Visual Studio. The book also shows you how to insert reusable blocks of code writing simple statements. Later, you will learn about visual aids and artificial intelligence that will help you improve productivity and understand what is going on in the project.By the end of this book, you will be able to set up your development environment using Visual Studio 2022, personalize the tools and layout, and use shortcuts and extensions to improve your productivity.

Creating machine images can be time-consuming and error-prone when done manually. HashiCorp Packer enables you to automate this process by defining the configuration in a simple, declarative syntax. This configuration is then used to create machine images for multiple environments and cloud providers.The book begins by showing you how to create your first manifest while helping you understand the available components. You’ll then configure the most common built-in builder options for Packer and use runtime provisioners to reconfigure a source image for desired tasks. You’ll also learn how to control logging for troubleshooting errors in complex builds and explore monitoring options for multiple logs at once. As you advance, you’ll build on your initial manifest for a local application that’ll easily migrate to another builder or cloud. The chapters also help you get to grips with basic container image options in different formats while scaling large builds in production. Finally, you’ll develop a life cycle and retention policy for images, automate packer builds, and protect your production environment from nefarious plugins.By the end of this book, you’ll be equipped to smoothen collaboration and reduce the risk of errors by creating machine images consistently and automatically based on your defined configuration.

Design patterns and idioms can widen our perspective byshowing us where to look, what to look at, and ultimatelyhow to see what we are looking at. At their best, patternsare a shorthand method of communicating better waysto code (writing less, more maintainable, and moreefficient code)This book starts with Haskell 98 and through the lens ofpatterns and idioms investigates the key advances andprogramming styles that together make modern Haskell.Your journey begins with the three pillars of Haskell.Then you'll experience the problem with Lazy I/O, togetherwith a solution. You'll also trace the hierarchy formedby Functor, Applicative, Arrow, and Monad. Next you'llexplore how Fold and Map are generalized by Foldableand Traversable, which in turn is unified in a broadercontext by functional Lenses. You'll delve more deeply intothe Type system, which will prepare you for an overviewof Generic programming. In conclusion you go to theedge of Haskell by investigating the Kind system andhow this relates to Dependently-typed programming

Haskell, with its power to optimize the code and its high performance, is a natural candidate for high performance programming. It is especially well suited to stacking abstractions high with a relatively low performance cost. This book addresses the challenges of writing efficient code with lazy evaluation and techniques often used to optimize the performance of Haskell programs. We open with an in-depth look at the evaluation of Haskell expressions and discuss optimization and benchmarking. You will learn to use parallelism and we'll explore the concept of streaming. We’ll demonstrate the benefits of running multithreaded and concurrent applications. Next we’ll guide you through various profiling tools that will help you identify performance issues in your program. We’ll end our journey by looking at GPGPU, Cloud and Functional Reactive Programming in Haskell. At the very end there is a catalogue of robust library recommendations with code samples.By the end of the book, you will be able to boost the performance of any app and prepare it to stand up to real-world punishment.

Opanuj niezwykłą sztukę wytwarzania oprogramowania! W jaki sposób zadowolić klienta? Jak wygląda proces wytwarzania oprogramowania? Jakie pułapki czekają na Ciebie? Proces wytwarzania oprogramowania -- już sam opis sugeruje trudności. I rzeczywiście -- jest to proces niezwykle złożony. Od samego początku trafiamy na kwestie takie, jak analiza potrzeb klienta i zebranie jego wymagań. Z każdym krokiem wszystko komplikuje się jeszcze bardziej... Konieczna jest implementacja poszczególnych wymagań klienta, testowanie tych rozwiązań, korekta znalezionych błędów. Na to wszystko nakłada się jeszcze konieczność tworzenia różnych wersji rozwiązań i zmienny nastrój klienta. Jak sobie z tym wszystkim poradzić? Jak bezboleśnie i skutecznie przejść przez cały ten proces? Tylko bez obaw! Oto podręcznik, który dzięki innowacyjnym metodom przekazywania wiedzy sprawi, że szybko zrozumiesz proces wytwarzania oprogramowania i nauczysz się gładko podążać jego wyboistą ścieżką. Autorzy książki "Head First Software Development. Edycja polska" -- Dan i Russ -- pokażą Ci, w jaki sposób zadowolić klienta i zebrać od niego wymagania oraz określić jego potrzeby. Dowiesz się, jak zapanować nad poszczególnymi wersjami Twojego projektu. Nauczysz się prowadzić testy i usuwać błędy. Zdobędziesz informacje dotyczące wytwarzania oprogramowania sterowanego testami, a na koniec zobaczysz, jak taki proces wygląda w rzeczywistości. Wszystkie te informacje przedstawione zostały na licznych ilustracjach, co wydatnie ułatwia przyswajanie wiedzy, dodatkowo przekazanej przystępnym i pełnym humoru językiem. Po lekturze tego podręcznika nawet laik będzie w stanie zarządzać takim procesem! Zbieranie wymagań Planowanie projektu Kontrola wersji Wytwarzanie sterowane testami Testy integracyjne Usuwanie błędów Tworzenie oprogramowania? Nic prostszego!!!
High Performance with MongoDB. Best practices for performance tuning, scaling, and architecture
Asya Kamsky, Ger Hartnett, Alex Bevilacqua, MongoDB...
With data as the new competitive edge, performance has become the need of the hour. As applications handle exponentially growing data and user demand for speed and reliability rises, three industry experts distill their decades of experience to offer you guidance on designing, building, and operating databases that deliver fast, scalable, and resilient experiences.MongoDB’s document model and distributed architecture provide powerful tools for modern applications, but unlocking their full potential requires a deep understanding of architecture, operational patterns, and tuning best practices. This MongoDB book takes a hands-on approach to diagnosing common performance issues and applying proven optimization strategies from schema design and indexing to storage engine tuning and resource management.Whether you’re optimizing a single replica set or scaling a sharded cluster, this book provides the tools to maximize deployment performance. Its modular chapters let you explore query optimization, connection management, and monitoring or follow a complete learning path to build a rock-solid performance foundation. With real-world case studies, code examples, and proven best practices, you’ll be ready to troubleshoot bottlenecks, scale efficiently, and keep MongoDB running at peak performance in even the most demanding production environments.

Node.js makes it easy to get started, but just as easy to get things wrong.How Not to Node.js takes a practical, no-nonsense approach to uncovering the most common mistakes developers make, and shows you exactly how to avoid them.The book is structured around real-world anti-patterns, guiding you through how to identify, understand, and fix problematic code. You’ll start by learning how patterns and anti-patterns shape application design, before diving into asynchronous pitfalls, event loop behavior, and error handling. As you progress, you’ll explore architectural concerns such as logging, middleware design, environment management, and API reliability.By the end, you won’t just know how to write Node.js code, you’ll know how to avoid writing bad Node.js code, building applications that are clean, scalable, and production-ready.
