Github has a couple of "fun" behaviours: 1) It links the email address in a commit to a github user with that address no matter who committed it 2) If a commit is pushed to a fork, it's visible in every fork (including the original)
Exciting news: "Python for Data Analysis, 3rd Edition" is coming later this year. There is now an open access web edition at https://t.co/Ufdobfkzka. The first 6 chapters (and appendices) are available now with the rest coming soon. Thanks to @quarto_dev for making this possible!
