Code as a Crime Scene in Practice

Level: Intermediate

We’ll never be able to understand large-scale systems from a single snapshot of the code. Instead, we need to understand how the code evolves and how the people who work on it are organized. In this workshop you'll learn novel analysis techniques to support both technical and organizational decisions around your codebase.

The techniques are based on software evolution. They use data from the most underused informational source that we have in our industry: our version-control systems. Combined with metaphors from forensic psychology you'll learn to analyze version-control data to:

• Identify the code that's most expensive to maintain amongst millions lines of code.

• Predict the modules that are most prone to defects.

• Detect architectural decay and learn to control it.

• Analyze different architectures such as layers and microservices.

Since large-scale software development is also a social activity, we'll make sure to cover techniques that let you:

• Build a knowledge map of your codebase.

• Understand how multiple developers influence code quality and what you can do about it.

• Get a psychological perspective on the challenges and pitfalls of large-scale development.

We'll analyze systems written in different languages such as C#, Java, and Scala. Since the techniques you'll learn are language agnostic, you will be able to apply them to your own codebase immediately. Once you've finished this workshop you'll have a completely new way to look at your codebase and experience of using the Empear Analysis Suite.

This workshop is delivered in a practical hands-on style. We'll mix theory with hands-on analyses. The exercises are done by analyzing real-world systems to find real problems.

All analyses are done with Empear AB's Analysis Suite and you will be provided with a trial version of the tools during the workshop.

This workshop is for programmers, software architects and technical leaders with programming experience.

While we use Git for the exercises, the tools aren't limited to Git and we'll also discuss how you use them with other version-control systems such as Subversion and Mercurial.
