Sometimes I develop feelings for books, scientific materials and tutorials. I wrote about this in Nostalgic Bibliography. One of the science books I had this experience with was Shaffer, C. Algorithm Analysis book. I wanted a lot to email Dr. Shaffer about how much I enjoyed his book, but I never found the best words, so I never did. Today I've noticed that I had the same feeling for Matt Holiday's <https://www.youtube.com/@mattkdvb5154> Go tutorial. I have a theory that he made this tutorial because he wanted to gain from time at home during the pandemic. Such a well spoken person and a great teacher. #Go and #Programming
