Title: Shoreline Bugs, the Smalltalk way Speaker: Tommaso Dal Sasso Thu, August 21, 2:30pm – 3:00pm Video Part1: https://www.youtube.com/watch?v=_PDQGlq4yxw Video Part2: https://www.youtube.com/watch?v=GgXdA-bcmyA Description Abstract: ShoreLine is a novel platform to manage the bug reporting process the Smalltalk way. The vision of ShoreLine is to empower developers with first-class bug descriptions exploiting Smalltalk's expressiveness. Currently Shoreline allows the user to automatically submit stacktraces generated from exceptions, and inspect and visualize them to detect bugs and the activity of the Pharo community. Bio: Tommaso Dal Sasso is a PhD student at the University of Lugano in the research group REVEAL of Prof. Dr. Michele Lanza.
