We have reworked the integration with the #mybinder platform, and you can now again interact with notebooks right in your browser (now using #JupyterLab instead of Jupyter Notebook).
As an example, here’s the notebook on dynamic slicing: https://mybinder.org/v2/gh/uds-se/debuggingbook/HEAD?labpath=docs%2Fnotebooks/Slicer.ipynb

You can access these from any chapter in https://www.debuggingbook.org via “Resources” → “Edit as Notebook”. Enjoy!
