The 3rd day of RubyKaigi 2010 (Afternoon)

In this afternoon, I attended these sessions:

• If the session has a movie in English, I just write summaries of the article. Please see that movies if you want more details.
• If the session has a movie in Japanese, I write the article with translating and little-summarizing.
• If the session has no movies in any languges, I try to write the article with little-summarizing.
• But, for Ceremonies and Lightning Talks, I only put the link of movies.
• And I don't translate Q&As in the article because these are the gift for attendees in there.

N.B. These summaries may be imprecise.

I speaked to Shay so much after his session. And I'm lucky to understand why Gestalt cannot run on moonlight.

And the last session of Chad was so many many volumes, then I summarize significantly, so you should watch the movie.
