A week-long rainy days have annoyed me so much here in Tokyo. Today, everything is shiny, and it is hot as usual. Tomorrow, Gov't is to lift the nationwide state of emergency finally. The situations have changed from the past before the coronavirus outbreak. Meanwhile, my life doesn't change during the state of emergency. As a research scientist, I don't rely on any special devices or external environments. A complaint is just slow-down of the speed of network systems, due to daily heavy use of newly-joining teleworkers. I have been already accustomed to survival of the new era before the post coronavirus era. It is same with other computer scientists, I believe.
