Weekly Notes 10/2023

This is my 1000th blog post. 2023 is also going to be the 20th year of my blogging. I will write a 20th-year blog post later, but I am surprised the average number of posts per year is 50. Except for 2007 (strange year of imports), other years have been relatively consistent. And in the last few years, it has been more than average.
