Dependency Management: The Cause of—and Solution to—All Supply Chain Problems - Eve Martin-Jones & Josie Anugerah, Google

How many dependencies does your software project have? How much confidence do you have in them? We say in open source there is safety in ‘eyes on the code’, but with supply chain attacks on the rise - who is really watching? Most software is built with hundreds if not thousands of direct and transitive dependencies, and those dependencies change every day. Our analysis shows that up to 20% of PyPI packages change their dependency graphs multiple times per week. Ensuring that each one of these dependencies is trustworthy is a daunting task. In this talk, Eve and Josie will share some stats and stories from their experiences building deps.dev. They'll look at what it means for a project to be healthy, dig into the complexities of dependency resolution algorithms, and recommend tools that can make practical dependency management possible if not easy.
