Folks,
I just did some history re-writing and force pushed to https://github.com/matplotlib/presentations/ to purge some files that were violating the GitHub TOS (plain-text dumps of information about the the committers to matplotlib/matplotlib) following [1]
The new master branch is at: 2b00326841d21780f2ff5a7b1d638c5147091faf
If you have a checkout of this repository please reset you local master to the current upstream
git reset --hard 2b00326841d21780f2ff5a7b1d638c5147091faf
