Continuing to the last diary,

About both "big data" and "open source" implementing full functions

the commonly observed features are

"Too big is not good"

The bigger objects are, the more difficult they are observed and managed totally.

My main work is to research something ( I am a "research engineer"), so I often read several books and materials simultaneously.

In this digital era, I feel unreasonable to open several books on the desk, however,

associating between these several information is too difficult for PC or smart-phone.

As a result, I am sorry that I have to install many display on the wall, and waste the electric power.

In my room, an opened Note PC is attached on the wall. my wife said "like opened and dried fish".

I mean,

"Too small is not good"

The smaller objects are, the more difficult they are observed and managed totally.

This means, even if it is big data, or source code, or PC or smart-phone,

"each of them is not good for human being"

might be true.

To resolve the problem,

"we have to embed USB I/F on the back of our neck, and connect our brains with computer systems"

might be the last method, I think.

I am not an aggressive riot security police of Interior Ministry, however I also want it.
