Scenes from Thanksgiving II

Scenes from Thanksgiving I

With reports from Pfizer/BioNTech and Moderna that the preliminary analysis of their data suggests a 95% effective vaccine (one each for each company) [1], I found myself wondering about the mathematics of vaccine effectiveness.

A little bit of math: vaccine efficacy

There are a lot of idiots on social media. This will come as no surprise to most of you (to the rest … well, chalk up one more). For example, in response to the COVID Tracking Project’s update of weekly COVID-19 infection, hospitalization, and death data, this was posted: Of […]

Adventures in Cloning

UPDATES: Last week, I started seeing the emails from my server: the disk hardware early failure detection system, known as SMART, was beginning to spot errors on a disk in the server that powers this domain (and a few others). I sort of plan for disk failures, but I hate […]
