Previously, I wrote a diary "Hair style not to give a threat".

At the first day of this Golden week, I have asked a barber for "Buzz-cut".

Why?

I met a women barber at the barber shop of one thousand yen.

I am sorry but I don't like cutting by women's barber without discrimination (but might be reverse discrimination).

I think that their skills are too polite.

They seem not to understand my reasons why I want have my hair cut.

There are "Hot", "Itchy", "Sullen" and "hard to read books".

When I asked her to have my hair cut just short, she tries it carefully and I don't put up with the process.

So I said,

"Buzz-cut", please

However she tried to do her best about "Buzz-cut", I was really surprised at her action.

I know that I am wrong.

Most women and men should care their hair cut, and I know I am a stranger.

-----

Mr.Ebata whose hair style is "Buzz-cut" is terrifying appearance. Off guard, when I stand in front of a mirror, I was surprised at my scary face.

I could divide bunch of school students leaving school into two walls, so I thought

"Oh, it's the Ten Commandments of Moses"

However it was O.K. until I was enjoying, the other day, I was in trouble by my hair style.

At the day, I had two events to meet outside's persons, and they could not recognize me at all. If I said hello, they seemed to be pow.

Thought I don't care my hair style at all, this hair style might be wrong for my business.

I wrote several times that the home server of my home was a notebook PC made in doubtful Germany which I picked up in Akihabara.

The PC works as not only home security server, but video server and printer server, but I have already given up the maintenance now.

Anyway, the response is heavy and slow.

The reaction of an icon and the menu needs for ten second to one minute, so I come to not want to do anything.

Well, I tried to make a light-weight Mail Agent with a slightly feeling on the server this afternoon.

I succeeded in the operation with the local machine, so I thought I was going to complete the work when I shifted it to the server.

"This was a mistake."

I do not buy a lottery and betting. Because I don't win.

I don't buy them, so it is natural that I don't win.

I do not even rarely game. Because I don't win.

I don't try them, so it is natural that I don't win.

In other words, in order to enjoy gambling and game, we need "peace of mind" to enjoy the precess of them.

And I don't have the "peace of mind".

-----

But in my case, if a computer appears between lottery betting and me, my paradigm is going to be changed dynamically.

When I make a program about probability of the lottery, prediction of betting, or strategy of the game, my interest and concentration come to be maximized suddenly.

However, for all of the nation, it is a kind of stressful to

"live their daily life to care of cars, which zoom through gates of hospital and convenience store"

Technologies, for example "auto (stop) driving technologies", might resolve this problem, however, in the present, nobody knows whether the technology works well in our society.

-----

Today, I want to propose "a society that is not based on using cars".

However, I have already said that cars are equal to social infrastructure, so it might be difficult to make cars disappear.

So, I propose to eliminate "updating system of driving license" and to start "expiring system of driving license in five years".

After expired, any people in Japan, should go to a driving school again, and take examination of both practical and paper (and perceptual disturbance).

Due to this system, many elderly persons must lose their driving license. But all people will get a fair deal absolutely.

Above all, it is up to them, because they cannot pass the examinations.

Of course, this measure will reduce numbers of automobile in Japan, and give destructive damage to Japanese automobile industries. In addition, the gross domestic product might be going down dynamically.

Moreover, when the measure were proposed, any ruling party, even if it is a big one, is going to be minority opposition party soon.

Changing the subject,

It is said that a circulation board has a function to promote communications in a neighborhood unit.

However I am negative against this opinion. I think it will be useful as a detector of abnormal condition for "living alone", and very persuasive.

Even if it is useful, I am afraid that it means "too late" to find the abnormal condition, when the circulation board was not passed normally.

First of all, I am a distributor of the board, and I also distribute it once a month.

However, even if it is "too late", I think "to detect" might be meaningful.

Because, "both air temperature and humidity become high from now."

-----

In my opinion, I want to propose to install the following system,

"to observe "living alone" by human detection sensor"

"to send the detections to the NA-server"

and I want to manage the server by the community of the NA.

(Of course, persons who can say "I do not care about my privacy even if there is a human sensor", can use this system)

For me, I can realize this system just by 10,000 Yen as installation cost and 300 Yen as operation cost. (Three systems has already been working at our parent's house and my house).

The breakdown is that Raspberry PI(5000 Yen), soracom(6000 Yen) and human detection sensor(300 Yen) and monthly communication cost (300 Yen / month).

Based on 100 solitude houses, one year's MTBF, I can manage the systems as volunteer efforts of NA. At least, the cost might be cheaper than to manage circulation boards.

Of course, this monitoring service will be uninsured, because they are the volunteer efforts of NA.

The story of the NHK text "100 minutes de masterpiece" is amazing-what has been said.

Recently I read the text of Immanuel Kant, Jos Ortega and Gasset Baruch De Spinozaand , but I am surprised by the feeling that "I understand it like "that water sucks into the sand".

I could not understand them at all in my 10's and 20's. So I am wondering why I can do.

My hypotheses are

(1) Above all, the NHK text "100 de masterpiece" is amazing

(2) Over time, I have experimented some of the examples in the philosophy book

I could make another hypothesis that "reading of philosophical books for young people is "a waste of time",if the hypothesis of (2) above is "true".

-----

By "100 minutes de name book (not original book)", I learned that the study of philosophy is extremely logical and developed them based on thorough skepticism (eg, "they did not believe in human goodness at all. Roughly speaking, based on "human malice")

And, they proposed a system to operate society by assembling and turning those "malice" well.

I thought that philosophers were designers of social systems by controlling human('s parameters), not bridges, roads, tax systems or laws.

However, although there are no quantitative evaluations or demonstration experiments except for hypotheses.

For three consecutive holidays in March of this year, I was at a ski resort when all of Japan was alert to the coronal disaster,

At that time, for the first time, I tried automatic driving of N-BOX on the highway.

"Well, I could drive easier"

Once my car captured the car in front, the car changed in auto-tracking mode, and I can leave to my car own choice

However, on the contrary, I was attacked by a violent drowsiness.

However, when I did not hold the steering wheel (or when I handled the steering wheel loosely), the warning alarm prevented it, and it also will prevent me from falling asleep.

-----

I wish the word "driving a car" disappeared in the early days, and all cars will be operation-controlled under a system managed by the government.

I was thinking that while watching the animation "PSYCHO-PASS".

I often watch the TV program whose title is "Akira Ikegami's News, Oh I got it!".

The themes in this program are easy to watch, as even I know about 60-70% of each themes

Last night's theme was about the contents of recent high school textbooks. I was looking at it quite seriously.

(This is also related to the theme of my next series).

The impression of the program, was

"Ikegami-san. He didn't touch on math, science subjects in general, or programming education, at all"

I've been trying to think of a topic in Mr. Ikegami's past programs that touched on math and science, however I can't remember.

But that's beside the point.

-----

The main character of my favorite novel/anime said,

"The Magazine of 25 Deviations"

and, disrespected a fashion magazine that his sister was reading.

The protagonist of the story is set up as a character who "hates mathematics," and this line alone gives a clear indication of this tendency.

This is because a "magazine with a deviation 25" is not commercially viable.

This is because "25 deviations" is not only an expression of "low intellectual level," but also an expression of "low probability of occurrence.

50 + 10 x Z = 25, Z = -2.5 σ.

If you read this value 0。00621 from the standard normal distribution. the number of buyers of the magazine is 6 out of 1000, at the most optimistic.

In addition, according to the magazine preferences, the radio is probably not even one in a thousand.

A school year has one million students. Half of that is 500,000 female students. 0.1% of that is 500 copies.

Even for junior high school students in grades 1-3, there are 1,500 copies nationwide.

By the way, the number of junior high schools in Japan is about 1,000.

It's clear that a magazine that can't handle an order of 10,000 is not commercially viable.

------

If you can't calculate like that, you can't do any business, even if you are not an engineer like me.

That's what I want Ikegami-san to talk about.

(By the way, this kind of approach is called "Fermi estimation")

-----

"Your criticism of the ignorance of 'a magazine with about 25 deviations' is a proof of your ignorance"

Hikigaya, you will be disrespected by Yukinoshita.

Usually, in early April, new employees who have just joined the company appear for on-the-job training (OJT) in window operations.

Naturally, since they are newcomers, their work will be slow, and in April, many people will gather at the counter for various procedures, making it crowded.

However, it can also be said that this is a "start-up period for the social system," a period that the people of Japan need to watch with warm eyes.

-----

Today, first thing in the morning, I went to the post office to send out an express registered mail. The person at the counter was a so-called senior uncle.

The uncle was probably a newcomer, with a younger bureau staff member by his side to assist him with business procedures.

He seemed to be confused, however, it could not be help.

About the express registered mail, the method to read a destination address changed to scan the envelopment( I don't have to write the address), I could use the credit cared, and get a receipt including the tracking number.

For me, as a users, these are very useful, however, the operator ( the uncle at the counter ) seemed to be hard to use various devices.

-----

The uncle is me of the future.

Let's all take care of our seniors (elderly).

They (I) have already finished the role of "weaker of society", and now they are expected as essential labors

In addition, they will be contributors to save national budget by rising the age of qualifying conditions.

-----

Now, the slogan of "Take care of elder people" is not completed. The phrase of "as important labors" will be added after the slogan.

I use my website as DataBase, using just the Google search engine and search functions of WordPress.

This is really useful.

Whenever I want to tell a story about a specified theme, I can find it soon.

-----

Today I was ordered to submit a short story about a specific theme, and I could find it in a few seconds.

Well some people should hear my story again and again, I ask them to give up.

-----

Anyway, my Web establishment was founded in 1993 -- a 30-year old Web site.

Well, in terms of scale, it's more of a "candy store" than a "wagashi ya" -- however,

Still, if you focus only on history, GAFAs like Amazon and Google are like little boys.

By no means is this a sore loser?
