full name: Cosma Shalizi
how we met: I found he is an interesting person, a tenured professor in CMU (same as Joel Chan) in statistics field and has been in Madison for a while. The whole story about how I met him was long and complex. I was mainly focused on the new Roam Research course at the very beginning. Then I tried to find out about the PDF highlighter, then I found it's coder also has posted some other hard work video on Youtube (a very much helpful video if someone need to read All of Statistics), also he seems to be very familiar with Albric. So I tried to find out more about ccc, in his late tweet, I found he seems to be a tenured professor and he reposted a link, which then refers to a wayback machine page, this was something that Cosma wrote when he was 40 (which is 14 years ago, on the day he got his tenured track). The article seems sad and depressed. Then I tried to search more about this guy.
actually the page was still available on his webpage
and here is another very sad paragraph about careers in academic: https://timchen1017.wordpress.com/2013/09/18/what-i-like-in-physics-and-why-i-eventually-choose-to-quit/
This is the wiki page if I search his name directly on Google. There is a real picture of him. He did not disappear like Philip Guo, still active but not in the way like many others
This is his personal home page on CMU, the last one I saw something like this was on Philip Guo's home page，but with much more stuff.
Here are a few pages that I am interested in:
Home page: http://bactra.org/ pain text, wierd pics, not welcoming students or such contact, but still welcome human emails
links: http://bactra.org/links.html very academic, nothing about personal interest
personal experience: http://bactra.org/personal.html He is a UWM alumni! His mother and father are all excellent science workers.
soft words about Madison: http://bactra.org/madison.html
Notebooks: http://bactra.org/notebooks/ basically are all booklists upon a certain topic
book reviews: http://bactra.org/reviews/ deep and decent work
Another secret web page？: Three-Toed Sloth
