    The hidden beauty of relational database systems
    Are you somewhat comfortable with using SQL to access data, but are curious to know what happens behind the scenes when you send off your
    query? Then this is the talk for you!
    Relational database systems have been around since the 1970s and they
    are stacked full of cool ideas and concepts for making data handling
    fast and secure. And we are still using them, nearly unchanged, 50 years
    later! Reason enough, I think, to learn a bit more about how they work
    and the fundamentals of their design.
    Audience level: If you have played around with SQL / written some
    smaller queries, you’ll be just fine.

    Katharina is a freelance data scientist | computer vision engineer | teacher.

    Let's exploit pickle, and skops to the rescue!
    The pickle format, and loading them, has many vulnerabilities, including the fact that loading them can lead to arbitrary code execution. In this session we demonstrate what some of those exploits are, and how to create a malicious pickle file.

    Then I present an alternative format from skops library which can be used to store scikit-learn based models. We talk about what the format is, and how persistence and loading is done, and what we do to prevent loading malicious objects.

    Adrin is working at Hugging Face and works on skops which tackles some of the MLOps challenges related to scikit-learn models. He has a PhD in Bioinformatics, has worked as a consultant, and in an algorithmic privacy and fairness team. He's also a core developer of scikit-learn and fairlearn.
