2018-02-22 文系の人こそが、プログラミングをして、シミュレータをサクサクと作る ―― そういう未来は、十分ありえます。 [長年日記]


(Continuation from yesterday)


By the way, a personal computer(PC) has enabled us to calculate behaviors of all people in Japan using virtual objects. I am afraid that

―― 人文系の学問の人達への大きなプレッシャーになっていくんだろうなぁ

"the face will increase the pressure for the person in human science field"



Before it was enough that

● 仮説 -> データや自分なりのロジック -> 検証

My hypothesis -> objective data or my logic -> my validation


However, now, I think that they should add the following activities, and

● 仮説 -> データや自分なりのロジック -> 数値シミュレーション/数理モデル -> 検証

My hypothesis -> objective data or my logic -> numerical simulation or mathematical model -> my validation


they will not avoid mathematical processes.

文系の人こそが、プログラミングをして、シミュレータをサクサクと作る ―― そういう未来は、十分ありえます。

Researchers with majors in the school of humanities, should produce simulation programs in large quantities. It is realistic future, I think.



Hereinafter, private communication from me


to my daughters


- Your father can teach programming to you.


- I am going to adjust to "Ancient spell language(C/C++), let's ask me an advice.


- If you don't have proper motivative example and problems, I will farm out to you.


- Before due date, I will pay for money.


The feeling that "the world is in this hand of me!" ss a pleasant sensation that I can not taste in daily life.

2018-02-21 なにしろ、私は、malloc(), free(),そして、コンピュータの生モツ(OS)に直接触れられるような ―― 「古代呪術言語」までをも操れる ―― 数少ない長老の一人と自負しております。 [長年日記]


You may know that I continue to make several kinds of "simulator" on a day-to-day basis.


Basically, I like to make simulation programs. Moreover I am a

―― C/C++という言語のネイティブ

"Native speaker of C/C++ (program) language.


even if the language has a bad reputation,


If there is a nation whose name is "C/C++ kingdom", I believe firmly that I don't have to worry about communication in the nation.


I don't need any illustrative sentence book and sightseeing brochure.

なにしろ、私は、malloc(), free(),そして、コンピュータの生モツ(OS)に直接触れられるような ―― 「古代呪術言語」までをも操れる ―― 数少ない長老の一人と自負しております。

Above all, I feel proud that I am one of wise old mans who can use "ancient spell language" that enables me to touch a computer operating system directly, with some system calls.



However, I am afraid that the words of "I like simulations" means, on the contrary, "I dislike mathematical model".

The other days, I wrote a story that my simulations duration became zero, by a mathematical model that a reader presented to me.


My enforced simulations (which use a lot of random numbers and objects) are

―― 醜悪で見苦しい

more "ugly and awful"


than mathematical models( based on statistic and differential equation)


Of course, it was true that the performance of computers of old was too poor to do the "enforced simulations"


So, we have always needed more computer performance, especially in the field of physical science, for example, magnetic, electric and weather analysis, there is no reason that we don't need any more performance.

2018-02-20 あの頃の私は、一体何を求めていたんだろう? ―― 今となっては、本当によく分からんのです。 [長年日記]


I enjoy an animation, whose title is "Yuru-camp"(means, "loose camping")

なぜか ――

The reason is

When I was young at the same age of the girl heroines, I had dome same types of camping (in fact, I think my camping was harder than them)

ただ、ですね ―― 「冬キャンプ」なんかやったら、本当に死ぬんじゃないか、と思うんですよ。

However, I am really afraid that "camping in winter" will let them die.


In my case,


- I was almost frozen to death, even in spring camping.


- A radio program of Aum Shinrikyo(before terror attack) frightened me to death.


- A snow avalanche that blocked a forest road, compelled me more than 50 km reroute


- I was washed away by the high waves near the sea.


―― どこが「ゆるキャン△」だ

"Where is Yuru-camp ?"


I repeatedly asked myself the same question unconsciously


"Hard camping", "Tough camping" or "Solid camping"


are suitable for my early days.


I think that I repeated punitive activites when I was young.

あの頃の私は、一体何を求めていたんだろう? ―― 今となっては、本当によく分からんのです。

"What did I want when I was young?" I don't know it at all by now.

2018-02-19 (2)江端家次女へ:最期のページの最終行を読んで、私に感想を送付すること [長年日記]


Today, new my column is released, so I take a day off.

Let's turn the world by "Number" : Work style reform(6) "

Governments and companies that confront with "side work" What are the benefits to workers?



My junior of my company took a big bite out of my this column.


To: my junior daughter: Read the last sentence in the last page, and give me your impression.


That's all

2018-02-18 文部科学省は、『「メシ」「服」「日曜大工」程度では、全然足りん』と言っているのです。 [長年日記]


(Continuation from yesterday)

In "Junior High School Study Instructor's Commentary Techniques / Home"(Ministry of Education, Culture, Sports, Science and Technology, July 2008) on p.27., there is a description of "soldering iron".


"The level that the state is requesting the citizens (children)" was surprisingly high.


Cooking, sewing and woodworking are naturally written, and furthermore, regarding the significance of "soldering iron", the following issues are described clearly.


(1) Learn about the function of current limiter, earth leakage circuit breaker etc. indoors


(2) Learn about the mechanism of using electrical equipment safely


(3) Learn to (a)prevent accidents such as equipment damage and electric shock due to electric leakage,(b) need Maintenance and inspection to continuously demonstrate the performance of the equipment in the best condition, through examining, the devices and examples of accidents caused by electrical equipment




In a word, that means,


"Even if the problem of electricity at home happens, you can fix it yourself"




The Ministry of Education, Culture, Sports, Science and Technology said "Cooking"," Clothes", and "Do-it-yourself" ar not enough".


One step is "soldering iron".


So I will withdraw my opinion of "The teacher of your school is stupid ?", and apologize to the teacher.


Both the Ministry of Education, Culture, Sports, Science and Technology and the teacher in the field, understand that what they have been doing properly.



And I will tell youth

私たちの国の政府は ―― 『けっこう、厳しいぞ』

Government of our country - "they are pretty tough"

2018-02-17 ―― お前の学校の教師って、バカか? [長年日記]


I heard a teacher makes students make "soldering iron" at my daughter's school.

―― お前の学校の教師って、バカか?

"The teacher of your school is stupid ?"


Accidently, I said such a line from my mouth.


「はんだごて」は、「はんだ」という金属を溶かして、電気や電子部品を電気的に接続するものですが ―― 当然、高温を発する危険な器具です。

"Soldering iron" is a device that melts metal "solder" and electrically connects electricity and electronic parts. However it is a dangerous device that generates high temperature.


Except for engineers like myself (I have a degree in "electrical engineering"),I do not know how many people know the existence of "soldering iron".

それ以上に、「自作のはんだごて」の使用は、それ自体が危険です ―― 私なら、安全基準をクリアした製品を購入させて、正し使い方を教えます。

More than that, the use of "home made soldering iron" is itself dangerous. I will let my daughter purchase mass commercial products with safety standards and teach how to use "soldering iron".


I let me make "drivers" at my junior high school, and we could buy "driver" at the 100 yen shop.


If I says, my own behavior ("self-made love") will also be denied, but still there should be a priority.



This priority should be done in technology and home economics classes.


(1) Cooking: Based on rice and miso soup, it is enough to tell two kinds of fried foods, simmered foods and pottery items with the rest of the ingredients.


(2) Sewing: Basic knowledge on repairing of broken parts, broken parts.


(3) Woodworking: Easy loading platform, bookshelf, shelves to make on the wall. It is sufficient to designate the dimensions in the DIY shop and cut it for wooden boards, in addition, how to use woodworking bonds and electric drivers.


After that, how to locate the main plug when the water pipe ruptures, how to contact when gas leaks etc.





"Acquisition of technology to live alone"


is important.


Technical home economics classes are no longer a practical study, beyond other subjects.

それが、「はんだごて」の作り方(×使い方)? 一体何考えているんだろう?

That is how to make "soldering iron" (How to use)? What on earth are you thinking?


Even my electrical engineer I cannot understand the reasons at all.

『しかし、本当に現場の教師がバカなんだろうか?』と思い、ちゃんと調べてみました ―― そして、意外な事実に驚きました。

I thought that "are they really stupid?" I examined it properly - and I was surprised by the surprising fact.

2018-02-16 長女:「パパの言うことは信じない。平気で嘘をつくから」 [長年日記]


This was the story when my family talked about "friends".


Ebata:"I don't have anyone who I can call a friend"


Senior Daughter(SD):"I don't believe you. You make no bones about telling lies"


Ebata:"Not telling lies. I dare to say that it is a "cheerful presentation""

SD:"In Singapore, when I saw that you talked with the taxi driver cheerfully, I decided that "You are a liar"


Ebata:"There is a limit to work it well for my daily business..."


SD:"It was true that you could use English abroad. So you are a liar"


Ebata:"It is your misunderstanding, How to explain it to you ..."


I made eye contact with my wife, and my wife said to her.

嫁さん:「つまりね、『パパの会社』や『パパの仕事』の内容から見れば、 ―― パパの程度の英語力では、全く『お話にならない』 ―― 訳なの。分かる?」

Wife:"Let me say... From the viewpoint of Papa's works and the company's qualities, Papa's English proficiency is "just a joke". Do you understand?"



Yes. I could agree with their opinions perfectly. However How do I felt that I was hurt doubly by them ?

2018-02-15 「恋人というのは、とかく高いところに登りたがるよなぁ」 [長年日記]


When I heard that my senior daughter had a date to Tokyo SkyTree, in spite of myself, I said


"Lovers are inclined to go high"



I also went to a bar and drink with my wife at the top floor of the highest building in Osaka. (After that, I moved to a pub at the underground of the building and had grilled chicken.)


Ebata:"There is a proverb of "smoke and foolish person are inclined to go high", so "Lovers become foolish accidentally" might be true."


Senior D:"as I recall, there used be a Twitter's comment of "When the Christmas comes, lovers are crowd around illuminated places. Are they insects?"


Ebata:"I thinks the lovers should become foolish insects. The time we become "foolish insect" is shorter in their life"


After hearing it, My wife said with admiration


Wife:"You tell a lot"


Ebata:"I talk about "love" enthusiastically."


Senior D:"I know. and it is long"


Junior D:"Repetitive"

2018-02-14 ―― 『あんなに、一生懸命働かなくても良かった』と後悔している [長年日記]


(Continuation from yesterday)


By the way, there is worth listening to a story that retired or terminal people said

―― 『あんなに、一生懸命働かなくても良かった』と後悔している

"I should not have worked harder, while be working"



We have already experimented on the several scenes in my life.


Especially we adults, know well that


"There is no meaningless relationships with friends of teenage era in our life"



However we, as working people, cannot say


"There is no meaningless hierarchical relation in our company"


We can forecast the future after our retire, but we cannot act to ignore the hierarchical relation because of worry and fear.



In conclusion, we can "take our life easy" but we don't have courage to "take our life easy" in a specific field and time.


After all, I think that we will

―― 「後悔することになる」ことを、折込済みで生きていくしかない

"regret our extreme worry and fear, at the time of retirement or end-of-life"


2018-02-13 脳の疲れ方が違うなぁ ―― と実感しています。 [長年日記]


I have been crazy for a programming for a few months.


However, I have left a lot of document works, so I had to stop the programming.


For a few days, I wrote and wrote documents, and I noticed that there are two types fatigue.


脳の疲れ方が違うなぁ ―― と実感しています。

I realize that the overloads of brain are different,


In case of the coding, I have to chase more than 1 million's object at the same time, so I am exhausted when going home.


In case of the writing, I have to make a story with a reasonable logic. Even if one collapse of the logic happens, I have to make another collapse in order to fix the previous collapse. That is a negative catenation, so called. Anyway I have been under a lot of stress.


Both of them are not "easy".


However my ultimate hope is "to live my life easily".


Of course, I want "money" and "honor", however I can exchange them with "easy" for me.


However, when we want to become a "easy" master, I think that I will lose not only "money" and "honor" but also "my favorite works". So it is difficult for me.
