It's also worth taking a look at the author's website: https://100r.co/ - ORCA is just one of many projects and explorations that they do while living on a boat.
that talk, where they discuss their experience living on and maintaining a sailboat, resonates with me very well right now. In quarantine, I'm having to learn how to fix things and basically be able to take care of the household. It feels like we are on a space ship, drifting through time, but basking in peace and solitude.
it's worth noting that they had a fantastic session at xoxo 2019, talking about the trials and successes of living on a boat. having lived on top of a mountain with satellite internet (not nearly as bad as their connection), I was able to sympathize with the unhappiness of Xcode updates.
