SummaryAs a developer, you may inherit projects built on existing codebases with design patterns, usage assumptions, infrastructure, and tooling from another time and another team. Fortunately, there are ways to breathe new life into legacy projects so you can maintain, improve, and scale them without fighting their limitations.Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.About the BookRe-Engineering Legacy Software is an experience-driven guide to revitalizing inherited projects. It covers refactoring, quality metrics, toolchain and workflow, continuous integration, infrastructure automation, and organizational culture. You''ll learn techniques for introducing dependency injection for code modularity, quantitatively measuring quality, and automating infrastructure. You''ll also develop practical processes for deciding whether to rewrite or refactor, organizing teams, and convincing management that quality matters. Core topics include deciphering and modularizing awkward code structures, integrating and automating tests, replacing outdated build systems, and using tools like Vagrant and Ansible for infrastructure automation. What''s InsideRefactoring legacy codebasesContinuous inspection and integrationAutomating legacy infrastructureNew tests for old codeModularizing monolithic projectsAbout the ReaderThis book is written for developers and team leads comfortable with an OO language like Java or C#.About the AuthorChris Birchall is a senior developer at the Guardian in London, working on the back-end services that power the website.Table of Contents

How does news circulate in a major post-industrial city? And how in turn are identities and differences formed and mediated through this circulation? This seminal work is the first to offer an empirical examination, and trace a city’s pattern of, news circulation.Encompassing a comprehensive range of practices involved in producing, circulating and consuming ‘news’ and recognizing the various ways in which individuals and groups may find out, follow and discuss local issues and events, The Mediated City critiques thinking that takes the centrality of certain news media as an unquestioned starting point. By doing so, it opens up a discussion: do we know what news is? What types of media constitute it? And why does it matter?
