(Continuation from yesterday)

Firstly I think an appellation.

What should I call this violence?

If it is difficult to say "Domestic violence(DV)" in this case, "International violence" might be good. But I am afraid that it is not good because that means international dispute or war.

"Upgrade violence(UV)"

That's it.

It is available even if "Up-version violence".

Some people might be confused with "ultraviolet(UV)" ,but both are almost same from the view of the danger or disgust.

I really come to think that I am going to move the linux(Ubuntu) environment.

But I have thought same things again and again for more than 20 years. Anyway numbers of windows application are tremendous, so I came back to the windows environment each time.

Well, for my engineers life, I have always repeated same things again and again(However, I am not retired now)

Maybe, this mind-set might be similar to the mind of person who cannot decide to divorce of the DV spouse.

But a life time as a engineer or a business person is not so long.

This time might be good for me to think out a preparation of divorcing with the Windows environment.
