PyCon 2019 Talk Resources

At PyCon US in 2019, I reprised my talk "The Black Magic of Python Wheels", originally presented at PyGotham 2018. I based this talk on my three years of work on auditwheel and the manylinux platform, hoping to share some dark details of how the proverbial sausage is made.

After this talk, I will be retiring from auditwheel maintainership.
