PyTN Profiles: Jessica McKellar and The Python Software Foundation

Speaker: Jessica McKellar (@jessicamckellar)


Jessica McKellar is an entrepreneur, software engineer, and open source developer from Cambridge, MA. She is a Director for the Python Software Foundation and an organizer for the largest Python user group in the world. With that group she runs the Boston Python Workshop — an introductory programming pipeline that has brought hundreds of women into the local Python community and is being replicated in cities across the US. Jessica is a veteran open source contributor and a maintainer for several open source projects, including OpenHatch and the Twisted event-driven networking engine; she wrote a chapter on Twisted for The Architecture of Open Source Applications Volume II and the second edition of O’Reilly’s Twisted Networking Essentials.

On Saturday, February 22nd at 1:35 p.m in the Auditorium, Jessica will be speaking about Building and breaking a Python sandbox. What does it take to make a Python sandbox that can run untrusted code? Learn some surprising language features and experience security challenges first-hand as we work through building a Python sandbox from scratch. You’ll leave this talk with renewed appreciation for the dynamic nature of Python, some sneaky language tricks, and a solid background in classes of sandboxing security issues.
