I recently spent a lot of time reviewing my Twitter data collection infrastructure in order to start some more collections. In that process, I discovered some tokens and streams I forgot about. The purpose of this post is to document what data I am collecting as of 04.29.2020 so that I have an easy reference […]
Starting with the 19th book review (Mao biography), I have decided to add a grade and, to counterbalance what can often seem like negative reviews, one interesting fact learned from each book. I aim for a B- average. The Sellout by Paul Beatty – Wow, what a novel. My wife bought it for me for […]
Tim Gunn (April 2019) – My wife always raves about the celebrities she saw while a student in NYC, so I was cautiously optimistic during a weekend we spent there. While we did not see anyone in the Village, we did cross paths with Tim Gunn as we walked from Levain Bakery to the Museum […]

I recently had a large dataset where I wanted to make a series of plots with different variables on the y-axis. I remembered that a few years ago I great frustrated that I could not do this with ggplot, so I moved on. This time, I was successful. The key, as this Stack Overflow answer […]
That headline misleads slightly: the 30L backpack is a good everyday bag if photography is part of your everyday. If your everyday involves traditional office work and commuting, I suggest looking elsewhere for a bag. That is what I did, and I own happily the Nomatic Backpack. The internet world is in love with all […]
While I have my issues with the tidyverse, one feature I am enamored with is the ability to assign values to observations in grouped data without aggregating the data. This assigning is done by using the mutate() command instead of summarize(). I am in the middle of some data processing in a Python pipeline where I […]
This one took me about 20-30 minutes to figure out today and required stringing together some SO answers, so I’m putting what I learned here for future reference.
