A week ago I went to Shanghai, China to attend and to give a talk at
RubyConf China. The day before the conferences first day a bunch of us
were invited to a VIP dinner where we met with Matz and got to play with
a
device running MRuby. And I heard that earlier on that day Matz was
adopted by a book publisher to do an interview.
I have found the interview (in Chinese), and found it to be really
useful.
So I translated it to English. Hope more people will like it.
