This month we will step into the world of software maintenance -- a reality for projects of all sizes. Join us to hear from Andy Snell on the topic of dead code as he walks us through how to identify and remove rot from a codebase.


Over time, and without careful maintenance, software projects tend to accumulate code and dependencies that just don’t belong in the code base anymore. Dead, rotting, and outdated code is a stumbling block to upgrading, refactoring, and maintaining legacy code, and at worse could become a security vulnerability. We’ll cover how to identify zombie code and dependencies, including using some newer tools built into PhpStorm and GitHub. We’ll also talk about different types of code tombstones and how to use them. Finally, we’ll discuss how to avoid having zombies in your code in the first place!
