RefactorHackathon‐2026‐III

Virtual Refactoring Hackathon III: September 16-18, 2026

General organization:

During the hackathon we will primarily focus on work related to the data refactoring project. This is the third quarterly hackathon dedicated to this project.

Dates were selected based on the results of a When2Meet Poll.

Hackathon rules:

• Three days will be dedicated to working on the refactor project.
• One daily check-in is planned, at 13:00 UTC (9 am EDT, 2 pm GMT, 3 pm CEST) via the usual Zoom link.
• Communication can be done through the SasView slack channel (#code-camp), or through the usual Zoom link.
• All work should be based off the refactoring branches in sasdata and sasview

Initial planning session

• An initial planning session will be during the technical meeting prior to the hackathon.
