Why did I stop my blog during about a year?
Actually, Nothing special :) But It had an accident on last posting day after next day. Self hosting server was crashed! So I could not do during stopping server. After that, I recovered server, But I had no motivation that time. Also I was working very hard. And I didn't have margin of mind.
Recently I have motivation and can write little English. Why did I post in English? I'll talk next time.
