Patterns of Software Construction: How to Predictably Build Results
by Stephen RylanderMaster how to implement a repeatable software construction system. This book closely examines how a system is designed to tie a series of activities together that are needed when building software-intensive systems. Software construction and operations don't get enough attention as a repeatable system. The world is stuck in agile backlog grooming sessions, and quality is not increasing. Companies' budgets are shrinking, and teams need a way to get more done with less, consistently. This topic is very relevant to our current economic conditions and continuing globalization trends. A reason we constantly need more hands-on-the-keyboards is because of all the waste created in development cycles. We need more literature on how to "do software" not just write software. These goals are accomplished using the concept of evolutions, much like the Navy SEALS train their team members. For LIFT, the evolutions are: Plan, Build, Test, Release, Operate and Manage. The entire purpose of the book is instructing professionals how to use these distinct evolutions while remaining agile. And then, inside of each evolution, to explicitly break down the inputs to the evolution, outputs and series of activities taking place. Patterns of Software Construction clearly outlines how together this becomes the system.What You Will LearnOptimize each evolution of a software delivery cycleReview best practices of planning, highest return in the build cycle, and ignored practices in test, release, and operate Apply the highest return techniques during the software build evolutionWho This Book is ForManagers, developers, tech lead, team lead, aspiring engineer, department leaders in corporations, executives, small business owner, IT Director

C++ Software Interoperability for Windows Programmers: Connecting to C#, R, and Python Clients
by Adam GladstoneGet up-to-speed quickly and connect modern code written in C#, R, and Python to an existing codebase written in C++. This book for practitioners is about software interoperability in a Windows environment from C++ to languages such as C#, R, and Python. Using a series of example projects, the book demonstrates how to connect a simple C++ codebase packaged as a static or dynamic library to modern clients written in C#, R, and Python. The book shows you how to develop the in-between components that allow disparate languages to communicate. This book addresses a fundamental question in software design: given an existing C++ codebase, how does one go about connecting that codebase to clients written in C#, R, and Python? How is the C++ functionality exposed to these clients? One answer may be to rewrite the existing codebase in the target language. This is rarely, if ever, feasible and this book’s goal is to save you the pain and the high cost of throwing out valuable existing code by showing you how to make that older code function alongside and with the more modern languages that are commonly in use today. The knowledge you will gain from reading this book will help you broaden your architectural choices and take advantage of the growing amount of talent around newer languages.What You Will LearnBuild components that connect C++ to other languagesTranslate between the C++ type system and the type systems of C#, R, and PythonWrite a managed assembly targeting the .NET frameworkCreate C++ packages for use in R/StudioDevelop Python modules based on high-performance C++ codeOvercome the difficulties and pitfalls involved in cross-language developmentWho This Book Is ForSoftware developers who are looking for ways to extend existing systems written in C++ using modern languages.

Beginning gRPC with ASP.NET Core 6: Build Applications using ASP.NET Core Razor Pages, Angular, and Best Practices in .NET 6
by Anthony GirettiBroaden your developer experience by learning how to use gRPC and ASP.NET Core together on the Microsoft’s developer framework, .NET 6 and discover a new way of developing APIs with gRPC. Beginning gRPC with ASP.NET Core 6 is your guide to quickly and efficiently getting down to the business of building gRPC applications in the Microsoft .NET ecosystem. Readers will dive in and build an application using gRPC and the latest technologies such Angular and ASP.NET Core Razor Pages. This book will teach you how to set up an efficient application using industry best practices such as security, monitoring, logging, and more. You will do this by performing Create, Read, Update, and Delete (CRUD) operations on a SQL Server database with Entity Framework Core. From there you will build web applications using Angular and ASP.NET Core Razor pages combined with gRPC APIs. After reading the book, you’ll be able to take advantage of the full range of developer opportunities with gRPC, and come away with any understanding of which usage scenarios are best suited for your projects. And you will possess a solid understanding of the best way to build APIs with ASP.NET Core. What You Will Learn Discover the latest .NET 6 framework Benefit from a new way to design APIs Build modern web applications Migrate easily from WCF to gRPC Become comfortable with latest industry programming standards Who This Book Is ForProfessional developers who are interested in getting started with gRPC and want to learn how to use it to build applications in the .NET ecosystem.
