2020-03-30 "So, this time, let's disclose all the codes" [長年日記]

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

Mr.Ebata's struggling for DIY IT Nursing Support System(4) "

Run! Raspberry Pi. Rescue your parents from stray cars


In the last column, I did not disclose the contents of the code for Raspberry Pi, but downloaded it as a package.

Because of that, I was told, "There are almost no articles (code, etc.) on Raspberry Pi."

"So, this time, let's disclose all the codes"

I thought that.

And it is supposed to be ugly (the other reasons are that I explained all three systems at once.)

So, if you are not interested in Raspberry Pi or code, you can skip to p.6.

The "Dr.Shibata, the overrun" has appeared and is developing a sharp theory.

That aside.


Many (engineers) reading this article do not have such a chance to try Raspberry Pi.

Then, "we can't go to the office / we can't let us go to the office" is now a chance for a thousand times (*).

(*)As of March 30, 2020, in order to prevent the spread of viral pathogens, local governments in downtown Tokyo have issued a request for residents to "stand by at home".

In an environment where your boss cannot watch you,

you can do it at home, and

It does not cost much,

You can study IT/OT technology

Such an opportunity may never come again.

If you can build and operate Raspberry Pi, you will not be able to know the "building" of AWS, but you will be able to do "operations" of AWS.


I feel like I'm still dreaming that I can use the UNIX-type operations I got when I joined the company.

The "dream" is a "nightmare".

Even now, I am honestly dissatisfied with the reality that UNIX-like operations are being used.

I thought that by 2020, the concepts of construction and operations would be gone, and that "artificial intelligence", "AI" would all do the job.

"Artificial intelligence", "AI", "artificial intelligence", etc. Really, they can't do anything. They are useless.

The reason why we must continue to use 1970 operations at the present, is that the basic architecture of computers has changed little after all.


Well, anyway, if you miss this opportunity, you may not have the chance anymore.

In this virus disaster, time will surely settle down, anywhere to settle down.

But a vague "study" attitude will definitely fail.

Then, let's set the goal to "complete one application".

It doesn't have to be the current nursing care IT system, it doesn't have to be a raspberry pi.

How about AWS? There is a one-year free package, so you can use it.


System construction and programming consume time stupidly.

It will let you experience several hours in about 30 minutes, and it is also the ultimate time-consuming (wasting) device.

You can shorten the time you feel stressed at home.

That's what I guarantee.

2020-03-28 From around 5 billion people around the world, there is a possibility slightly that "men who crushed the Olympics" will be attracted attention on SNS with figures and pictures. [長年日記]

(Continuation from yesterday)

When I was worried, I received an e-mail from a doctor whose name "Dr.Shibata, as a transgressor". who helped me in writing the column

With his consent, we will disclose the full text below.

===== From here =====

I agree with simulation.

The reasons are followings,

- I want to calculate the time until the acquisition of population immunity by simulation

- There is no rodent or infectious disease that has an exponential function forever. A future that will always be steady or disappearing will be shown

- Coming to see the goal, everyone will do their best

- If the worst result comes out, measures can be taken to prevent it from happening

- The simulation contributes to social benefit comprehensively

For now, there is an opinion against simulation in my mind.

- Maybe the Diamond Princess (the infection) will be spread to Japan, there is no wonder if more than 10 million infected people, 10% of Japanese people, are estimated to be sweet.

- 2 times in 2 weeks, 1000 times in 20 weeks, At present, 10,000 people should be infected. Unless the population immunity effect is taken into account to exceed 10 million people, the possibility of reaching in 5 months can not be thrown away

If it is hit with a detailed simulation, it will surely be a big flame ...

- If he put it in the numbers, such as "the number of patients surpassing 10 million during the Olympics", it would be troublesome to be managed by the government and strange organizations ...

- Mr.Ebata will protect my personal information, but I wonder if Ebata himself is OK...

This is the reason for my dissent.


Honestly, I think the Olympics will collapse on its own.

I think that this will collapse inevitably naturally.

However, if Mr.Ebata hit a high impact number at this moment, there is a possibility that "the figures will be used by the opposition in the Diet."

"Japan should die" will be returned.

The government may be remorseful that Mr. Ebata has crushed the Olympics.

From around 5 billion people around the world, there is a possibility slightly that "men who crushed the Olympics" will be attracted attention on SNS with figures and pictures.

(If it happens, I feel like Mr.Ebata can live as YouTuber)

Even if Mr.Ebata doesn't use the numbers, I'm sure EE Times Japan readers can understand what I want to say.


I'm sneaky, so I can't say "No" for Ebata's simulation here.

Mr.Ebata's wife is probably the last line of defense to protect the Ebata family.

If she tells Mr.Ebata "No", I will give up.

In this age, peace for wife and daughter is more important than for social justice.

Please tell your wife that never withhold me or social justice.

===== To here =====

This email was received immediately after this diary, but now I reread it,

"Dr.Shibata could predict the future accurately"


"I failed to become the man who crushed the Olympics

I had the above impressions.


However, at a later date, a mail told me that there is no possibility of "man who crushed the Olympics."

(To be continued)

2020-03-27 If I sort out the results of this simulation, I may be able to watch an insane and nasty (virtual) reality. [長年日記]

Before, I wrote a diary "I'm worried about whether or not to simulate the infection of coronavirus (COVID-19)"

In fact, I've been working on creating a simple simulator (C/C ++) using a virtual city traffic simulation (railway and bus only) as a hobby for the past year or so.

Currently, as many (virtual) humans as the ordinance-designated cities can be moved on my personal computer.

However, I thought that it would take a little more than 2 hours for a simulation of 20 hours a day, so it couldn't be used easily.(For an one hour future prediction, 10 minutes is enough)

And the bottleneck of this simulator is "moving".

In the U.S. presidential election, I don't have to move people to polling places. In this simulator, 100 units of trains and buses, and tens of thousands to hundreds of thousands of people move at a stretch and must track them in seconds.

To be honest, when I start calculating this simulation, I feel like I can hear a scream from my computer.


So, when I thought, "It is difficult to use it as a simulator as it is" "I wonder if a day's simulation can be done in about 20 minutes" and about remodeling, this new corona infection disaster occurred.

I've been playing with a variety of predictive techniques so far, I could not predict the spread of the new corona infection disaster.

The current reality is far from reality.

Also, with this simulator, I can't do simulations of school closures, or simulations of midnight Shinjuku and Shibuya drunks.

All I can do is a city traffic simulation in a virtual city on the premise of commuting to work.

In this simulation, throwing in a certain number of corona infected people and roughly determining the infection rate according to the riding rate, I can watch the number of infected people increasing just keeping turning the computer.

By the way, because of me, deaths according to age will also be counted.

If I sort out the results of this simulation, I may be able to watch an insane and nasty (virtual) reality.

(It's very unusual, however) I thought, "I don't want to see the simulation results"

2020-03-26 "In order to entertain themselves, they who have to assume the existence of others are "weak"" [長年日記]

The word "corona fatigue" seems to be popular, but I haven't changed much.

Even in the same building, there are some changes, such as using a telephone conference system, but there are also some benefits, if it is a meaningless meeting. Because I can do internal work (for example, writing a diary),

Well, we Japanese has the concept of "scheduled harmony" and "synchronization pressure", so we must not ignore such a meeting.

Teleconferencing is a very useful tool for coordinating things around you.

So, I think, "when it comes to video conferencing. I am in trouble"


To the mind of people who can only act with someone, It may be a difficult time these days that there is a request to ban going out to prevent transmission of COVID-19,

For me, "it's easier to move alone", so "going out requests" are not a benefit, but a disadvantage.

For internal operations, the remote office environment was in place before this panic began.

Home programming environment is enough for program creation.

To build a system, a cloud (AWS, etc.) is enough (well, I can manage them because it's for research purposes).

On weekends, when I'm focused on something, I'm basically one person.


It is said that there are benefits, for person whose attributes are "social life", "gloomy person", and "party animal"

"In order to entertain themselves, they who have to assume the existence of others are "weak""

Of course, it may be desirable to have such "positive" qualities (though I don't need it).

However, in addition to this,

"Whatever the world says, no matter what they think, You can act alone and entertain yourself"

I think that if you can have the qualities of such a "lone", you will have a sense of security (I don't know if you can be strong).


It is wasteful to say that "corona fatigue" and so on.

Now, you should think of it as an opportunity to establish and nurture an "lone" within yourself.

Speaking of what you can do with "lone", reading, watching movies, jogging, climbing mountains, and others are good. The content doesn't matter.

The important thing is to keep the "engine that drives "myself" anytime.

2020-03-25 "Can "EE Times Japan" catch this intense content?" [長年日記]

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

Let's turn over the world by number (62). Extra:

"A forefront of corona infection battle" sent by a doctor to an engineer


I read the email from Dr.Shibata at a ski restaurant on Saturday.

Before reading the full text, I came to the conviction that this email should be disclosed.


I want to reach this content to as many people as possible, but only a few people can understand this content correctly.

I'm sorry Dr.Shibata if the content message is broken because of an inappropriate comment.

If so, the target is still a science-based technology group. In that case, is it better to ask the EE Times Japan editorial department?

I was shaken by the lift while thinking about that.


While sending an e-mail requesting permission to publish to Dr.Shibata on Sunday, I changed the format of the email I received for EE Times Japan.

But I hardly needed to fix it.

_ I

suppose that both Dr.Shibata and I were the same technicians trained in Technical Writing.

After receiving permission from Dr.Shibata, the text file was sent to the EE Times Japan editorial department with haste.

"Can "EE Times Japan" catch this intense content?"

I was worried.

So, at the same time, I was preparing to launch on my site.


The next day, I was surprised when I received the email from Ms.M in charge, "Mr. Ebata. Go ahead!"

I thought "they have guts" and better of EE Times Japan.

("Let me think that EE Times Japan is a publisher with a professional Ms.M who is in charge of editing and proofreading of "Real-time Simulation of Railway Dive Suicide")

After that, I stood between Mr. Shibata and Mr. M, the editor, and focused on the modification work.

Working until 4:00 am on Monday and 3:00 am on Tuesday, and being released on Wednesday morning. so amazing speed release was realized.


"We will do open this treasure in the world". This column was the result of Ms.M's and my strong obsession on the sacrifice of Dr.Shibata

2020-03-24 "The effect of the diet method changes dramatically depending on individual differences." [長年日記]

I had previously contributed a series of diets using myself as a sample.

I'm still collecting weight data, and now I've come to understand my own tendency to change in weight.

In addition, I have been interviewing my family and have come to understand the basic principles of diet.

That is,

"The effect of the diet method changes dramatically depending on individual differences."


Basically, in my case it was "drinking".

Overeating or exercising on weekends and holidays, it's relatively easy to return to my normal weight on weekdays.

Alcohol is both a lethal beverage and a high-efficiency / high-concentration energy supplement beverage.

An extreme example is "one or more cans is equal to one serving." It's almost like a drip to drink.

Conversely, "chocolate" is an important item as an overeating controller.

In particular, bite-chocolate is, to me, a “pill” for appetite loss.


I was talking about it in my living room, and I got a protest from my second daughter(SD).


Ebata: "What?"

SD: "If chocolate is in front of me, it's good manners to eat it all, That is chocolate"

Ebata: "Well, no, I don't think so. I'm spending about 3 days for a piece of chocolate."

SD: "It's a bad way to eat chocolate. It is sorry for chocolate. It's the chocolate's lifetime that ranges from a chocolate bar appears in front of me, to disappears from my view.


"The effect of the diet method changes dramatically depending on individual differences."

This "individual differences" includes person's personality, and preferences, and qualities,

and their own beliefs (or religions).

2020-03-23 Even if there is really the researcher, "you are stupid." [長年日記]

"I hate the word" big data "or" AI "from the bottom of my heart" has already been sickly talked about for two years.

Nevertheless, the word "AI" has been used internally.

Of course, all researchers around me have to use the word "AI", after fully understanding the emptiness of words,

If there is a researcher who seriously thinks "a technology called "AI" exists", I would say "you are a liar".

Even if there is really the researcher, "you are stupid."


The other day, when I was having dinner in the company cafeteria, I received a phone call from the rude junior.

The content was a request for research in the next term

Junior:"Nobody is proper for this request except for Mr.Ebata, who is Big data authority and AI specialist" "

Ebata: "You are fighting me?"

2020-03-22 Ebata: "Well, you think H company's products is so good don't you ? Ha-ha-ha" [長年日記]

I've been talking about I "hate" the phrase "Japan's world-class technology" many times before.

"What did you do to develop this technology on earth ?"

I've been saying it all the time.


The other day, my home washing machine was broken.

This miracle machine has been running for 18 years.

My wife inquired me about "repair or replacement", so I suggested "repair".

However, she strongly insisted on “replacement”.

Ebata: "You don't have to make inquiries from the beginning. I know that the longest person (my wife) has the right to decide."

Wife: "If I do not properly pass the decision, I cannot get an advice for the replacement from an engineer(me).

Indeed, it seems that buying a washing machine alone was "heavy" for her.


The following was conversation with a clerk at a mass retailer.

Clerk: "Company P and Company H are excellent in washing machines"

Ebata: "Which company is your recommended?"

Clerk: "Just my taste, but I would recommend this "H Company" washing machine overwhelmingly."

Ebata: "Well, you think H company's products is so good don't you ? Ha-ha-ha"


I am not involved in the manufacture of washing machines, and I am not so happy if the H company's products is complimented.

Of course, not. So, if I am asked

"What did you do to develop this washing machine on earth ?"

Of course, I have not been doing anything.

2020-03-21 "30 years of hardship. I, today, went down the moogulose course." [長年日記]

I replaced my broken ski boots and bought used ski boots online.

I have to use it because I bought it, so I went skiing on the middle of a three-day holiday.

By the way, it seems that the daughter (senior daughter) who wanted companionship (parasitic) decided to go with her boyfriend the next day.

They seem to try the first board ski in their life.

I thought, "Is it okay for beginners?", however, I thought it was not my business.


Ski resorts will be was quite deserted, I thought, however, I was wrong.

I was not able to enter the first parking lot, so I had to the second parking lot, and I was carried by shuttle transportation to arrive the ski plaec.

And in the last few years, I have seen the largest number of ski place.

Thinking about it, skiing is a fairly safe leisure activity to avoid two of the three major requirements for virus infection. (distance from humans, not enclosed space (by skis and boards))

In addition, my "Solo Ski" has the advantage of "no conversation needed".

Ski resort cafeterias may be at higher risk of infection, however, It was fine because I had a solo lunch at a remote place.


I was attacking the same moogulose course all day, however, I couldn't skid well and was hit off the course, after all.

In such cases, I know that I should think logically. and I came to think of

"How about geo-fence routing to minimize the vertical kinetic energy?"

(You don't know what I was thinking but it's understandable for a researcher who wander the deadline during an outdoor experiment.)

I magined a geofence on the sides of snow convexs, and made them blink on after another in my head. and kept stepping on the geofence --- I was able to glimpse down the moogulose course.

I was glad and sent a LINE message to my family, saying, "Win with the GIS (*) approach."

"30 years of hardship. I, today, went down the moogulose course."

(*)Geographic Information System


However, all subsequent trials failed.

It has been decided to enter the 31st year of hardship.

2020-03-20 "Numbers become violent". I know this very well. [長年日記]

Recently, I have been thinking about infection simulation for coronavirus (COVID-19).

We talked about this simulation and about releasing it to the public.

My wife, the editor in charge of my columns , and that "rude junior", said

"Stop it"

Well, this column will be a risk that goes beyond "setting foot in the minefield"

A half-heartedly persuasive column (whether or not you agree) may be a factor in causing social confusion.


This is life-threatening.

I should not work with ease.

Government(Ministry of Education, Culture, Sports, Science and Technology) that did not disclose to the public about the simulation results of the emergency rapid radioactivity impact prediction network system (SPEEDI) after the nuclear accident occurred immediately

might have thought the same things as I think.


I think my column basically falls into the category of "amateur shit".

So I don't think that I need to be as cautious as the government.

However, even if it was "amateur shit", I know well that when formulas and computers come in, people tend to be silent.

"Numbers become violent". I know this very well.


I am thinking now "What should I do?"
