The other day, I got the loan of a DVD, whose title is "NUMBERS".

Now the drama is broadcasting through broadcasting satellite(BS).

This week theme was "prime number".

-----

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

We know well that some prime number 1,3,5,7,11.. for example, but it seems to be difficult to find big prime numbers, because we cannot know how to find out the numbers.

If someone could make this algorism or find the method, it is said that the electric commerce business, hotel and flight reservation system, and international exchange market are going to

collapse.

All kinds of encrypted data in computers and on networks are ready to be decoded.

Story of "Elliptic Curve Cryptography" will be at some future date.

-----

Against this "nobody know where the big prime numbers appear", there is "Riemann Hypothes" that can estimate where they appear.

This week "NUMBERS" would show a electric cracking to national bank using the big prime number by this "Riemann Hypothes". I was really excited.

I don't know how to make the discovery program from "Riemann Hypothes", but I don't care it at all. the drama is the drama.

However I didn't know the program story at all.

-----

It was for heavy snowing on last Friday.

The recoding picture showed storming of block noises despite of electromagnetic radiation suppressor.

It was likely to be devastating electric wave troubles.

-----

Prime Number, cipher, Riemann Hypothes

Who has thrown a drama date with these special topics to a historical heavy snowfall day in Japan?

(Continuation from yesterday)

Early morning at five A.M. one week before the examination.

It was just zero degrees centigrade when I confirmed temperature in the car while seeing the blink of the frozen star.

In the cold indoor, I put my notePC tied a communications on assistant driver's seat. And I left for station nearby just in time.

After stopping at the station for a few minutes, I watched the time table of the train, and I kept driving the road I had simulated the previous day accurately.

When I went to the hill area, I saw that the morning sun was rising, and I started biting an apple as a breakfast.

When I arrived at the rotary of the transfer station of the train, I wrote my arrival time at my cell-phone memo. Waiting for the scheduled time, I started again driving to the examination school.

I got the route information from my car navigation system and went ahead through the complicated small road. It was three minutes later in the time of the train arrival station near the school.

"The result is not bad"

-----

The operation I thought was "driving my car linked with a time tables of the train”

(Continuation from yesterday)

A couple of a woman and man are standing on the train platform of both side. and watching them each other, face to face. They seem to wait for the last train with feeling sorry.

The telop of their mind is coming in the scene.

"I should not have noticed the time of the train"

"I should not have taken care of the time of the train"

For the meanwhile, the trains is coming on her platform.

The man sends her off with sigh.

But the woman keeps standing on the platform thought the train has gone, with smiling bashfully.

The man also start smiling little by little synchronising her smile.

-----

I think that my junior daughter is likely to shut "This productive couple must die!" whenever she watch the CM (She is a daily Odakyu-Dentetsu user as a commuter), however, this is a good CM that makes us feel ease.

Well, not only this CM but also many CM in these days, become high-quality finished form, like a fancy movies.

But any CM should be have their messages, for example. expansion of goods or services, enhance their image, and strength of firm. And the CM should carry the messages to the end-users.

"What is the message of this CM ? " I have been turning over in my mind.

(To be continued)

The "Valentine's Day" seems to be a more scary event than we are thinking (especially men).

During my family trip this time, I talked about this "Valentine's Day" event, however, it turned out that there is a tremendous misunderstanding between the female team and the men team (only me)

In the first place, I thought that "Valentine's Day" event is just a event of confession of love from women to men, literally.

Therefore, I thought that the event is an unrelated event for those who do not receive confession, and (this is important) the "obligation chocolate" was just thinking about "margin" of that event.

I also thought that "return" to "obligation chocolate" is something like the extra of the "Valentine's Day" event.

-----

My eldest daughter: "What's the story about it from above?"

Ebata: "As for the event" Valentine ", people those who are not in romantic relationships are just "outsiders" aren't they?

Second daughter: "Do you know how much effort we are making chocolate, do not you?"

Ebata: "Yeah, honest, I was scared."

My eldest daughter: "What does it mean "there is no return" against that effort!"

Ebata: "Yeah, I know what you want to say. But, for talking about your excessive costs, I believe that "men who have received obligation chocolate"cannot understand it at all."

My eldest daughter: "What?"

Ebata: "It's a chocolate. But it is not the chocolate except for a favorite chocolate for men"

(To be continued)

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.

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 ?

(Continuation from yesterday)

Ebata:"Do you want to get mails from your friends or coworkers?"

Woman:"I sometimes get a mail from coworkers, however I seldom replay to it, "Read only"

Ebata:"Do you feel the input characters annoy you ?"

Woman:"At the beginning, I needed much time for it, however, my daughter helps me"

Ebata:"I am sorry for querying you a lot. To tell you the truth, I am a member of a neighborhood association(NA), and I am really in trouble that some people don't want to use e-mails"

At that time, I wanted to say that "sabotage terrorism of them", however, I was interviewing a person who don't use e-mail, so I could not say it.

-----

Woman:"Lack of their can-do spirit?"

Ebata:"I know that person come to lose the spirits easily, if they face the trouble"

Woman:"How about going to join a PC class ?"

Ebata:"The class gives them one or two house in a week at most, and it might be a rare case if a trouble happened in the class"

Woman:"Well, I remember that I was in trouble that I could not answer the question about.. how to say "mail address"? I could not do any response of a person"

Ebata:"And?"

Woman:"My daughter told me that "Mom, Pass your phone to the person in front" and I did what she said"

Ebata: "... (speechless)"

It seems that it is not a story of such dimension any longer, such as information leakage or security.

I thought that if phone numbers or mail address list leaked out it would not be a problem for herself. But, of course I remained silent.

-----

Somehow I understood.

In other words, for PCs and mails,

(1) When you are in trouble, people who support you ("her daughter" in the case of the above woman) will tell you the side

(2) Even if the personal computer can not be used, a person ("her husband") who acts for that will tell the side

(3) There is a clear reason ("Contact with her daughter") for using e-mails and personal computers

If these three conditions are not established, PC and mail can not work.

-----

In order to establish these conditions,

(A) At least, one person in a situation where it is necessary to use a personal computer at work, etc.

(B) At least, one person of other generation who can use e-mail etc. is as usual communication means

(C) At least, one person who can not contact unless you use mail

are needed, and that means, she must be a "member" of a "small group" of "non-profit" of "24 hours sales".

At that time, I noticed,

"It is "family" isn't it?"

-----

"Okay, a family is an essential team for "IT literacy."

I could understand it deeply.

Recently, I received an e-mail from a conference requesting an offer (suggestion) for holding a symposium plan.

I ignored the email all the time because "I can't afford to think about that in a second." However, I suddenly came up with the follow today.

-----

"MaaS symposium where only researchers and engineers who have fought in the field in outdoor (field) experiments can participate"

I'm starting to think like that.

-----

Idea,

Conept,

Simulation, and

Future forecast, trend analysis,

For those who are presenting brilliantly using beautiful PowerPoint pictures,

"Shut up, this stupid"

Now, I'm seriously angry with this kind of persons.

-----

Microcomputer causing kernel panic of unknown cause

Battery that can not secure the standard electricity,

Inaccurate positioning device that interferes with other correction systems

Web communication that real-time display cannot be realized as expected

Cloud server with ridiculous in-house authority that can't even get a TLS certificate

IC card system or QR code that cannot properly authenticate the user

Engaged in system tuning and maintenance while preserving sanity in a prefabricated building without heating or cooling

This "symposium where only people who have properly experienced the hell that seems to go crazy can participate"

-----

With such a symposium, I would be glad to be the secretariat, the chair, or the invited speaker.

So, at the welcome party, I would like to hold a tournament for the real name of "Shut up! this stupid!!"

This is a memo of an IT researcher who wants to cut corners as much as possible and use a computer to quickly solve the task at hand.

I described this down in the time to walk to the doctor's office and wait in the waiting room.

This memo alone contains about three inventions (although they are algorithms and hardly "patentable inventions").

If anyone can understand what is written in this memo, please let me know.

Some people may think that this memo is only for Ebata, who is "lazy" and has "dirty handwriting, however,

This is what all the researchers in the world write down when they are thinking about something (really).

My second daughter is a member of a Butoh(dancing) club at university.

Just practicing in the park, they get complaints from nearby residents.

As we talked about this, another stories were appeared.

"They get complaints that junior high and high school students spread out all over the sidewalk on their way to school, interfering with walking"

"They get complaints about junior high and high school students piling up at the convenience store near the station"

-----

Ebata: "Yes, of course there is the 'it's annoying' part, but that's not the essential reason"

Daughter: "What's that?"

Ebata: "The fact that the 'winners' who have the special privilege of being young are 'enjoying themselves' is unpleasant in itself. Well, that's for sure. I can't help but understand that feeling.

Daughter: "That's unreasonable."

Ebata: "Of course it's unreasonable. The ultimate in unreasonableness, I suppose. But for those of us who are not young, who have never had any fun, and who never plan to have any in the future -- You are an abomination"

Daughter: "..."

Ebata: "So I want you to be careful. There are a surprising number of people who can't recognize unreasonableness and can't control their actions with reason. And it's not just in Odakyu and Keio."

----

I was about to suggest to my second daughter, "Why don't you dance like you're not having fun, like you're lethargic? --- But, I stopped it.

I am willing to try any technology that interests me once it is worth the cost and time.

The results may be disclosed to the public if we determine that the information is not "confidential" or detrimental to the company.

This is not a law-abiding spirit or love for the company; it is a promise (contract).

I have many more stories, some of which I have decided to 'take to my grave.

Aside from that.

-----

I enjoy experimenting with techniques I am interested in, but being forced to do techniques I am not interested in is painful.

I have a technique that intuitively tells me, 'This technique is no good.

For example, they are known as buzzwords.

I try to avoid those technologies, but sometimes, I have to work on them because of work orders.

Occasionally, as expected, it was a no-no, but this can be surprisingly interesting if I am reluctant to work on it.

Nevertheless, if it is a no-no or not, certain results must be achieved if it is a work order.

I may be assigned to work on a technology that I think is no good, produce predictably bad results, and then be reprimanded by my superiors and executives for it -- this is unreasonable and painful.

What I'm trying to say is,

"We are not in control of our own lives."

It is a common story.

Right now, my second daughter is job hunting, to great acclaim.

As I watched, I felt sad, thinking, 'She, too, is going to start a life she cannot control.

Aside from that.

-----

The 30%:50%:70% rule is the ratio of college, high school, and secondary school graduates who leave the workforce within three years.

This has not changed in the last 20 years.

Whether one sees this law as "tragic" or "deserved" depends on one's point of view.

However, from the perspective of the current government's stated goal of "workforce mobility," the opposite can be seen.

The 90%:90%:90% rule is a world in which 90% of new hires leave their jobs within three years. If this can be achieved, the fluidity of the Japanese workforce will be assured.

I don't know if it will increase productivity (well, it will decrease...dramatically).

-----

The mobility of the workforce is,

(1) Not all newly created jobs will be enjoyable for everyone.

(2) To cope with the newly created work, it is necessary to study all over again from the beginning.

We need to face the reality that

Either way, it is probably true that the mobility of the workforce is hampered by what many people consider a "hassle.

If it's something you love, it won't be painful to study again -- but, for many people, studying is painful.

It is natural for anyone to want to "make the rest of my life easy, using only what I have learned through hard work.
