III Workshop on Software Visualization, Evolution, and Maintenance (VEM)

MotivationDebugging

Is very adopted

Is an effective practice for software investigation/comprehension

Helps developers to construct their knowledge

But…

Is an unexplored area

An isolated/individual activity

Motivation

Then…

How can we develop tools/practices tohelping this task?

How to share their acquired knowledgeduring a debbuging session?

Motivation

Our approach

Collecting and sharing debugging sessioninformation

Create new visualizations and searchingtools
