A newsletter on data privacy by Katharine Jarmul


Probably Private is a newsletter for privacy and data science enthusiasts. Whether you are here to learn about data science via the lens of privacy, or the other way around, this newsletter aims to be an open conversation on technical and social aspects of privacy and its intersections with surveillance, law, technology, mathematics and probability.
