Anti-Patterns in the Wild

Anti-patterns make code harder to understand for the human programmer and hence hide defects and make adding new functionality harder. However, little data exists on which anti-patterns occur in real-world software. This is a pity, because academic researchers cannot gauge which direction has most impact, and programmers have to re-evaluate which approach work best in practice.

We took a look our main Erlang project and identified which anti-patterns actually caused defects in the product. In this talk we give examples of the most common anti-patterns found, and which defects they caused. We evaluate tools and libraries to remove these commonly found anti-patterns.

Talk objectives:

• Share anti-patterns found in Erlang programs and our experiences with tools and libraries to remove these anti-patterns.

Target audience:

• Engineers who want to learn about dealing with anti-patterns. C programmers that are new to Erlang. Researchers who want to learn about anti-patterns in the wild.
