PyGotham 2018 Talk Resources

At PyGotham in 2018, I gave a talk called "The Black Magic of Python Wheels". I based this talk on my two years of work on auditwheel and the manylinux platform, hoping to share some dark details of how the proverbial sausage is made.

It was a fun talk, and I enjoyed the opportunity to wear my Python Packaging Authority hat:
