June 9 - June 15
I was in New York City this week for work. It has taken me a few years to stick to a routine when traveling.

Training

I used the hotel gym to lift each morning, making small adjustments to use only dumbbells and cables. I also went for a few runs along the West Side Highway. Back in San Francisco, I rode to Mill Valley and back. The only thing I’d change about this week is how front-loaded the weightlifting was. It meant taking three days off until lifting again the following Monday.
Health metrics


Being in New certainly helped with daily steps. The runs, combined with walking around the city each day contributed enough. Sunday and Friday are the days of the flights. Sleep was not as good as I expected. Perhaps the adjustment to the different time zone affected me. The average was also brought down by a 5.5 hour night Thursday, where I went out with my team.
Languages
I did not really study at all this week. I am still on Unit 9 of 22 of Section 2 (A1) of Duolingo’s French course. I completed 1 lesson.

What I read, watched, listened to
Netflix recently released a documentary on the Titan Submersible implosion. It is highly critical of OceanGate founder Stockton Rush. Many OceanGate engineers who raised safety concerns either quit or were fired by Rush. Rush repeatedly refused to have the submarine tested by a third-party, likely knowing that the tests would fail.
This is a great example of how LLMs can help with performance investigations. In my day-to-day work, I often share stack traces with LLMs to get an opinion on why a crash occurred.
I’ve been doing more work with Claude Code. Using these tools is a skill in and of itself, and the right way of prompting can mean the difference between saving an hour or having the code not work at all.
