There is not much to say about it but the underline is that it was a really nice experience to meet Ruby community in Japan and came to the birth place of Ruby at Matsue, Japan.
I met several Ruby Core commiters, Creator of MacRuby and lead developer of RubyMotion (Laurent Sansonetti), Writer of “Ruby Under a Microscope” (Pat Shaughnessy) and many others.
I hope that i can contribute more to Ruby community and Open Source community in general in my own way :)
