Re: Obituary for Christian Haider

by Tim Mackinnon

As others have mentioned - what a fitting description , and if you haven’t also seen one of his last presentations on UKST he described very bravely some of the changes he was grappling with and as always had a very meta description on how your mind can adjust to changes and perspectives. He shared so much with all of us.

Re: Obituary for Christian Haider

by stephane ducasse

Thanks peter for sharing with us this super sad news. I’m shocked. If someone of the group wants to present a little presentation at ESUG on what Christian did as a tribute please propose something may be on PDFTalk and values. A couple of years ago I tried to help porting it to Pharo and got distracted.

Survey: Identifying and Fixing Undesirable Behaviors Across Software Versions

by Remi Dufloer

Hello, As part of my PhD at the University of Lille, I am currently conducting a study on how developers handle certain bug scenarios. The goal is to better understand current practices, the tools used, and developers' needs regarding debugging in a specific scenario. Link to the questionnaire: [ https://sondages.inria.fr/index.php/566958?lang=en | https://sondages.inria.fr/index.php/566958?lang=en ] Your participation in this short questionnaire (5 - 10 minutes) would greatly help us analyze existing methods and identify potential gaps in the available solutions. This survey will be open for 6 weeks (Until May 15th, 2025) . The responses will be analyzed and included in a scientific publication. The results will be available [ https://remidufloer.github.io/Dufloer.github.io/survey.html | here ] . If you can, please feel free to share this questionnaire with other developers who might be interested. Every response counts and will contribute to a better understanding of the community's practices! A big thank you for your help and time. Best regards, Rémi Dufloer PhD Student, University of Lille ------------------------------------------------ ------------------------------------------------ ------------------------------------------------ ------------------------------------------------ ------------------------------------------------ Bonjour , Dans le cadre de ma thèse à l’Université de Lille, je mène actuellement une étude sur la manière dont les développeurs gèrent certains scénarios de bugs.
