Worked on environment hygiene and configuration cleanup for the Prof-Drake-UMD/INST767-Sp25 repository, focusing on improving the onboarding experience in JupyterLab. Addressed configuration drift by removing the obsolete .jupyter/desktop-workspaces directory and its contents, effectively resetting the environment to a clean default state for all users. This approach reduced user confusion, minimized support overhead, and improved reproducibility of notebooks and environments. Utilized Git for repository management, Unix command-line operations for file handling, and applied best practices in change management. Maintained clear, focused commits to ensure traceability and auditing, demonstrating attention to repository hygiene and sustainable workspace configuration practices.
