Hello, everyone. My name is Itoyanagi. I'm a climber, in particular, I do a lot of sawanobori. It is said that "the best way to enjoy the mountains is Sawanobori," so I wade through rapids in the wilderness, climb waterfalls, sometimes procure food locally, sleep by the fire, and head for the headwaters.
I was supposed to give a technical presentation on the riverside, as I always do in my online presentations, but I couldn't make it at all. So, I just spliced together some random footage from some mountains, and overlaid a technical explanation on top of it.
First of all, let me explain what the schedule was like this time. When I was accepted to RubyKaigi, I hadn't implemented any of the accepted features. This is a rough technique called "Kaigi Driven Development" that Ruby committers often use to make progress by taking advantage of the fact that they will have to implement the content to present it. The deadline for submitting videos for this year's English presentation was August 31s
