The speech by Matz was interested. Many people will write good essay. So, I write nothing about that. ;)


This session was also gooood. I can’t speak English (I’m Japanese) but he can speak Japenese (He is not Japanese). But, I guess the people who are not Japanese wanted him to speak in English… ;)

I’m interested in reduce memory usage of Ruby’s code (not C).

Lunch Session

I didn’t get a lunch box. Because RubyKaigi’s lunch time was so early for me. I didn’t know why.

Then, I take a Ramen.
