To Vienna I write this while sitting on a plane flying just south of Ottawa. We are early in the flight. We departed Toronto a little behind schedule and will land in Vienna, Austria around 08:30 local time tomorrow. The in-flight meal has not been served, and we are in […]
Tomorrow I will board a plane at the Sudbury airport and, connecting through Toronto, depart for Fredericton, New Brunswick. I am excited about this for at least a two reasons. First, this coming week is the Canadian Association of Physicists (CAP) annual Congress. The week-long meeting will bring students, post-docs, […]
It has been a long time since I was crammed in a big unpleasant crowd of people. Let’s take stock of the last three years. My last major international trip was at the very beginning of March 2020. Outbound from Dallas to CERN, the planes were semi-normal (more masking than […]
After two negative COVID-19 antigen tests this past week, I returned to in-person work. I kept myself masked in the office, especially when I was around anyone else. When alone in my own office, or eating in a more open public area, I lost the mask (unless someone showed up […]

The World Health Organization declared SARS-CoV-2 a global pandemic on 11 March 2020. At the time, I was isolating at home after returning from CERN. I was not allowed on campus because I had been abroad when my university declared that all international travel for work purposes was ended. But […]
Updated on September 16, 2025: A reader noted I referred to 192.168.1.50 at one point as the “Web Server”, but this was a typo. I should have said “Media Server”. I have made edits to clarify example IP addresses where the main web server and where the media server are […]
