• We used to share logic/components among our web products with an internal package
  • Which explains why when I went to investigate the inner workings of an actively-used legacy product there was basically nothing in the repo
• Troubleshooting an intermittent infinite loop which only occurs on mobile and seems to not send anything to Sentry is not fun
• Remember to reinstall your formatter after uninstalling everything to fix another issue
  • Also you need to reinstall it with :Mason, even if :checkhealth says it's there and fine (at least for my Neovim setup)
• When you extract logic for deciding which experiment you're using, don't forget to extract the logic which returns undefined in production
• Mixpanel takes a while to populate events (5-10min)
• Safari is the only browser which throws errors if fetch is interrupted by a navigation/refresh
• Rails can log a HTTP status of 0 for responses
  • Still trying to figure out exactly what that means, but from context not anything good
• The time to ask for help from a senior is probably slightly before "three full days spent on a support ticket"
  • In my defense the only other dev on my team was out for the last two days, and I didn't want to bother the senior senior without exhausting my own ideas
