Why Good Codebases Go Bad (And How to Stop It)
Is your code already legacy? Dave Farley breaks down legacy code in software engineering, proving it isn't defined by age or old tech like Cobol—it’s defined by testability and the cost of change. Learn how software developers inadvertently build technical debt into modern software engineering, whether programming in Python, C++, or Java. Discover practical software testing and refactoring strategies to stop creating legacy systems today. - 🧠 OUR SOFTWARE ENGINEERING TRAINING COURSES: https://courses.cd.training/ TDD Courses ➡️ https://courses.cd.training/pages/test-driven-development Discount on ATDD Course + Claude ATDD Skill ➡️ https://bit.ly/4rSAONz Save 30% NOW and get my ATDD Skill FREE With this course, you will learn how to create better requirements, with more precise prompts, and create better tools to actively drive the development process, working iteratively and verifying each small step, to improve your AI-generated code.
