Things I’ve found in checked-in notebooks: * database credentials. * sensitive data * a whole DataBricks webpage because the person didn’t understand how to export just the notebook. * collections of notebooks named only what step in the process they are, and literally nothing about what they actually do. * Whole base64 encoded images and zip files * packages imported by manually manipulating system environment paths * multi-processing/multithreading by shelling out and calling new python instances * good old “don’t run these cells”
