At both the Ebata's house and my wife's house, "Raspberry PI", that is a board computer whose price is just 5000 yen, is going to work well as a home security server.

Up to now, several PC servers had often been system down,so I think the "Raspberry PI" of MTBF is incredible for me.

(Although it can not be evaluated by MTBF because they have never been down yet)

Anyway, I think that "Raspberry PI" comes to be a symbolic existence supporting the field side IoT from now on.

Aside from that.

I thought that Cloud (remote server + INTERNET) is going to incorporate not only "information field" but "control field", however, "control field" has not lost either.

In addition, I am surprised that the fact that the architecture of more than 50 years ago is working normally (UNIX OS or C) in both fields.

The reason I am sticking to C/C++ is that it is not superior(no,no it is great indeed) but I don't want to learn more another programming language.

The code I write (dynamically generating memory blurry and processing with pointer) is the worst readability, impossible to share, further, unnecessary for diversion, totally it is the worst thing.

"It is O.K. if I can read the code"

I think it simply. "Why should I think about other people?"

I deeply thank to "the architecture of more than 50 years ago is working normally"

Well, I know my program is at least the worst; nevertheless, I think it is difficult to overtake my program from the view of execution speed.

My code is likely that I touch the inside of the computer directly by hand.

As an image, it is a savage code like "a prayer mentor in an undisclosed area, inserting bare hand into organs".
