Refactoring at Scale
Making significant changes to large, complex codebases is a daunting task--one that's nearly impossible to do successfully unless you have the right team, tools, and mindset. If your application is in need of a substantial overhaul and you're unsure how to go about implementing those changes in a sustainable way, then this book is for you. Software engineer Maude Lemaire walks you through the entire refactoring process from start to finish. You'll learn from her experience driving performance and refactoring efforts at Slack during a period of critical growth, including two case studies illustrating the impact these techniques can have in the real world. This book will help you achieve a newfound ability to productively introduce important changes in your codebase. Understand how code degrades and why some degradation is inevitable Quantify and qualify the state of your codebase before refactoring Draft a well-scoped execution plan with strategic milestones Win support from engineering leadership Build and coordinate a team best suited for the project Communicate effectively inside and outside your team Adopt best practices for successfully executing the refactor
Tidy First?
Tidying up messy software is a must. And that means breaking up the code to make it more readable, and using guard clauses and helping functions to make it understandable. In this practical guide, author Kent Beck, creator of Extreme Programming and pioneer of software patterns, suggests when and where you might apply tidyings in your code. Instead of trying to master tidying all at once, this book lets you try out a few examples that make sense for your problem. If you have a big function containing many lines of code, you'll learn how to logically divide it into smaller chunks. Along the way, you'll learn the theory behind software design: coupling, cohesion, discounted cash flows, and optionality.
Refactoring at Scale
Maintaining large applications is difficult, but supporting large, disorganized applications is nearly impossible. If you're unable to rapidly ship changes to your code without introducing new bugs or causing outages, perhaps it's time to slow down and consider a significant refactor. With this practical guide, software engineer Maude Lemaire teaches you how to identify and solve problematic patterns in your codebase. You'll learn techniques to help you effectively plan and execute a refactor spanning extensive surface areas of your application. Drawing from Lemaire's experience driving performance and refactoring efforts at Slack during a period of critical growth, this book helps you achieve newfound developer productivity throughout your organization. You'll learn how to: Identify the benefits of refactoring: bug squashing, developer productivity, and performance optimization Understand and articulate what's wrong with your current code Document and measure the impact of a refactoring effort Bring together the best team for the job Build sustainable coding practices and a healthier codebase

Beyond Legacy Code
We're losing tens of billions of dollars a year on broken software, and great new ideas such as agile development and Scrum don't always pay off. But there's hope. The nine software development practices in Beyond Legacy Code are designed to solve the problems facing our industry. Discover why these practices work, not just how they work, and dramatically increase the quality and maintainability of any software project. These nine practices could save the software industry. Beyond Legacy Code is filled with practical, hands-on advice and a common-sense exploration of why technical practices such as refactoring and test-first development are critical to building maintainable software. Discove...
Чистый дизайн. Практика эмпирического проектирования ПО
Грязный код создает проблемы. Чтобы код было проще читать, проходится проводить его очистку, разбивая на части, с которыми удобно работать. Кент Бек, создатель методологии экстремального программирования и первопроходец в области паттернов проектирования, рассказывает нам, где и когда лучше проводить очистку для улучшения кода с учетом общей структуры системы. Книга не заставл...
Масштабируемый рефакторинг. Возвращаем контроль над кодом
Поддерживать большие приложения сложно, а поддержка больших «неорганизованных» приложений превращается в непосильную задачу. Пришло время сделать паузу и задуматься о рефакторинге! Внесение значительных изменений в крупную и сложную кодовую базу — нетривиальная задача, которую практически невозможно успешно выполнить без рабочей команды, инструментов и планирования. Мод Лемер раскрывает все тайны рефакторинга на примере двух исследований. Вы научитесь эффективно вносить важные изменения в кодовую базу, узнаете, как деградирует код и почему иногда это неизбежно.
Deep'n as it Come
The spring and summer of 1927, the Mississippi River and its tributaries flooded from Cairo, Illinois, to New Orleans, Louisiana, and the Gulf of Mexico, tearing through seven states, sometimes spreading out to nearly one hundred miles across. Pete Daniel's Deep'n as It Come, available again in a new format, chronicles the worst flood in the history of the South and re-creates, with extraordinary immediacy, the Mississippi River's devastating assault on property and lives. Daniel weaves his narrative with newspaper and firsthand accounts, interviews with survivors, official reports, and over 140 contemporary photographs. The story of the common refugee who suffered most from the effects of t...
Working Effectively with Legacy Code
Get more out of your legacy systems: more performance, functionality, reliability, and manageability Is your code easy to change? Can you get nearly instantaneous feedback when you do change it? Do you understand it? If the answer to any of these questions is no, you have legacy code, and it is draining time and money away from your development efforts. In this book, Michael Feathers offers start-to-finish strategies for working more effectively with large, untested legacy code bases. This book draws on material Michael created for his renowned Object Mentor seminars: techniques Michael has used in mentoring to help hundreds of developers, technical managers, and testers bring their legacy s...
