One board computer, "Raspberry Pi" is enormous great.

Constructions and installs will be completed by just one command line.

There is no desired about the performance as a private server.

In special, it is very good that there is no physical driving mechanism.

Because any device that moves and circles is frangible basically.

Mouse, keyboard and display were installed just one time without problems.

In conclusion, it is "simple"

-----

You might think "what Ebata wants to say on earth?", so I will tell you my stories of the past.

As for "one broad micro computer" of the past.

- Firstly, I failed to show any message on the display. So I had to make a image of the message in my mind, and input the command and return the key. Of course, I failed it over and over again.

- Secondly, the keyboard output stranger characters, so I had to make a conversion table by myself.

- Thirdly, I had to install device drivers again and again to use the mouse,

- Finally the micro computer was ruined by conflicts among device drivers.

Anyway, "one broad micro computer" is grand sum of my nightmare for me.

However, I don't want to say "Today's young people don't know the burdens" like complaint of old.

"Simple" is justice at any case.

I think that "technology succession" is to make it more simple and leave the "justice" to the next generation.

By the way, technologies of "simple" that really surprised me are,

"Hatsune Miku", "Baysian network","Unity", "EtherCAT" and "Raspberry Pi". though,

"bigdata" and "AI" are not left in my mind at all.
