Sometimes, I get fan letter (mail) from my blog's readers.

It makes me feel perky.

There seems to be the topics of “English", "GID", "and accident at a nuclear power generation plant".

If my works make someone happy and are useful for them, I can feel happy.

-----

The other day, I got a mail, including the following phase.

"I can meet "Steins;Gate". Thank you so much "

Though I think that this is not for me, but for "Steins;Gate" itself,

Without my intention, I might claim that

"Regardless of age, anything good is good, even if it is animation and comic."

"If you worry about your age, you lose your life".

If I have sent the above messages to someone, I think that it is O.K. for you to thank me.

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

Mr.Ebata's struggling for DIY Home Security System by EtherCAT(5) "Telepathy communication between master and maids"

-----

"This is a serialization of EtherCat isn't it? Ebata-san, What are you doing on earth?"

with turning a cold shoulder to me,

driving almost all of my work modify, after discussing the meeting with the editor in charge,

the junior coworker

has existed.

The other day, I went to a workshop of industrial network in Ota-ku Tokyo.

All the day, I attended some lecture of standard organization, however, I was in trouble that I came to view the lectures critically.

I kept writing the articles of EtherCAT,

I made the EtherCAT master in my home PC, and

I constructed the EtherCAT slaves with diving under the floor.

"I am bound to hear the lectures from the viewpoint of EtherCAT specifications"

I am bound to see EtherCAT in a favorable light.

like the followings.

-----

"Long the transfer period"

"Why re-trial of frame transfer against communication error ? Easy to continue to transfer the same frames ?"

"Does it need to a special slot to communicate with slaves ? Other protocol like SDO is enough isn't it?"

(with Kansai accent)

-----

Almost for one year, I have been drawing "maids" that are personified as EtherCAT slave, so

I cannot grasp other standards of industrial network objectively.

I will prefer not to go this workshop next year.

However, tidal waves are coming suddenly in this field, so I should have an eye open full-time.

When I had an event of a neighborhood association the other day, I talked with a person who is working with the public relations work together.

I thought that I wanted to lay Internet lines in public hall in the town. Considering the current facilities and the budget of the neighborhood association, it seems to be difficult.

Meanwhile, since I heard the information that an administrative agencies have installed a network line in the public halls, I said as usual,

Ebata: "If we can break into the network line, it is illegal to

At he moment, I felt that my opponent's body got stiff and entered into alert mode.

"Can you do that, Ebata-san ?"

-----

Of course,

- For wired networks, I cannot analyze protocols except for EtherNet,

- Even if it is a wireless LAN, I cannot break password except for light security (short on WEP code)

- above all, the cost of hacking is more expensive than making a contract with provider overwhelmingly.

However,

Perhaps the problem is not there.

People who was called "Ebata",

has the option" hacking" in variety of possibilities.

It might be enough for ordinary people to enter into alert mode.

-----

I felt that I had to pay attention to "conversation mode", when I am in my company or neighborhood association.

For several days, I continue the story of "Izumo Taisha", and the popular story about the god "Ookuninushi-no-Mikoto" is as "god of marriage".

Whenever I go to a shrine, I am looking forward to watching messages of votive tablet.(It it bad taste). However, the concept of "Izumo-Taisha"

Most of the contents say "I would like to have a good match".I think that few things pointed to a specific person "I would like to marry Mr./Ms. XXXXXX."

Among them, one of the greatest impact are the following two.

"Breaking bad match, I hope that good match is coming."

This was the first time I saw a handwritten character "bad match".

"The store manager of ◯◯ store in Kashiwa City,◯◯◯◯" will divorce with his wife's ◯◯◯◯ and he will marry me ◯◯◯◯ "(◯ is all real name)

I do not want to know what happened and I do not want to know, but I think that your wish will not make everyone happy (including you). Well, let you begin with studying common sense of "personal information protection" for the first time.

-----

I thought that I would buy a "good match amulet" to my daughters at the shrine, however, I decided to refrain from doing it. I should not bear the risk of being accused of being sexually harassed by my family.

After talking back home, I got angry from my girls unexpectedly.

"When I was accused by the second daughter of high school," why did not you buy it!

I thought "How do you think a school girl who want to a "good match amulet""

Of course I did not say any extra things.

(Continuation from yesterday)

For example, besides the above convenience store books,

- Lectures of retired senior executives (order to attend as an instruction)

- Venture Company Success Story Articles

- Fighting illness record, up to "relive" by entertainer jailed with stimulant

- Process for children being abused by parents to get over it and build a happy family

The reason why I say "offensive" while admitting that these contents have a certain value.

is, despite the fact that the case from now on is "super rare",

arrogance to show as if it were "100% realizable with your own effort".

------

- The fact that many retired workers are likely to die due to their emptiness

- The fact that more than 90% of entrepreneurship ends with failure

- The fact that the recidivism rate due to stimulants is slightly over 60%

- The fact that abused children chain their abuse when they become parents

-----

"Somehow, I was getting angry"

I want to check for yourself, confirm for yourself

"my failure"

"my little ability"

"my intolerance"

and open them by myself more.

(Although I have already exposed my poor English skills in this diary etc.).

-----

With Angie's words, "The reward for what I did hard, is only what I did hard"

I want to scream at the center of the world.

"Almost nothing to realize "100%" with my own effort"

The conference secretariat has adopted my conference paper and I am now preparing materials for the conference presentation.

If you are presenting at a conventional conference, you usually go to the venue where the conference is held, take the stage, and present your work.

However, due to the corona disaster, most of the presentations at the conference are now all "video images + web exhibition".

In other words,

The concept of a conference hall is eliminated, and there is no need to speak at the conference. Naturally, you won't have to worry about making a mistake in your presentation.

No more real time spoken English question and answer sessions. The alternative is to write on a bulletin board (text).

-----

"How marvelous this is!"

I think that.

That's what I'm advocating in this column.

First principle: don't "have" a topic that would require discussion in English.

Second principle: don't "create" a topic that would require discussion in English.

Third principle: "Don't let them bring in" topics that would require discussion in English.

It is the realization of a world where none of this is necessary.

If the corona disaster continues indefinitely -- for our country, which has a large population of "Engineer not loved by English", this might be,

"A Little Bit of Gospel"

Recently, the Bitcoin rate seems to be fluctuating wildly again.

Every day, I would get a pop-up message on my phone.

Recently, the rate had been going down, but with the "Amazon's official adoption" story, it went up again and I just saw the news that "Amazon denies the report".

It would be fine if it were only a local currency, but Bitcoin is, after all, internationally circulated.

But as a rule, no one can govern bitcon (well, I recently learned the reality of a wildly popular "hard fork").

In fact, Bitcoin is useless as a payment currency (except for dark side operations).

-----

There is a "history" of nations adjusting the amount of money in circulation, conducting necessary diplomacy, and even going to war if necessary, in order to protect the value of their currency.

So I am wondering that what the "country that adopted Bitcoin as legal tender (El Sadbadr)" is thinking"

They say it's for "remittance purposes for foreign migrants," but no matter how you look at it, I just don't see how the citizens of a country that doesn't have the power to have its own currency and uses the U.S. dollar as the de facto legal tender can be trusted with Bitcoin.

In the first place, a currency that fluctuates wildly depending on whether or not it is adopted by a single EC company based on a single comment by some CTO is difficult to use as a currency, and in fact, there are almost no places in Japan where it can be used.

To begin with, one of the purposes of currency is "to be able to buy food today at the same price tomorrow.

-----

I don't care if the bitcoin rate is 1 BTC = 100 yen, 1 million yen, or 10 million yen.

I just hope that soon the value of Bitcoin as a speculative currency will disappear and it can be used as a stable currency.

It would be great if Bitcoin could gain credibility and stabilize rates by being adopted by a huge platformer like Amazon.

However, as long as I see the rate against legal tender doubling or halving depending on the news -- frankly, I think it's 'not worth talking about'.

Honestly speaking, I voted the ruling-party in the last Upper House election, and I regret it.

Separation of government and religion is a principle of democracy.

Of couse, I deeply understand that a politician is always a "device" the reflects the will of some organization.

As for religious organizations, I believe that we "decide to separate policics from religion", however we ensure "overwhelming preferetial treatment in the tax exemption system", instead of that.

If I misunderstand it, let you teach me correct answers.

I am surprised to know that a current member of the LDP Diet has publicly state that he asked the Unification Church to help himt gather votes.

In addition, the fact that the media can so easily expose the video clips, means that the clips has not been kept secret.

Is there any difference between "I asked the Unification Church to get votes" and "I asked XXXX, a designated gangster, to get votes"?

I don't know that, so please give me the explaination about that.

It is hard to believe that even the prime minister of a country was involved with the Unification Church.

Shame on you.

"Fuji School Mametan Research Annex" by Yuri Shibamura of "Marginal Operation" is a must-read for every researcher in Japan.

"Mametan" is a small (1 meter x 1 meter x 1 meter) robot tank that also appears in Marginal Operations.

Detailed specifications for "Mametan" were included, which were not listed in "Marginal Operation."

With all this information, I thought the author could generate a blueprint of "Mametan" in CAD, but unfortunately, there was no blueprint in the book.

However, I thought,

If this is detailed in CAD, the Chinese People's Liberation Army may develop it before the Japanese Ministry of Defense does."

It occurred to me that from the perspective of our national security, it may be the right thing to do not to generate blueprints in CAD.

(Of course, I think there are still some issues with "Mametan" in terms of operation in the field, but that's called "SF.")

Aside from that.

-----

I consider this book a must-read for all researchers in Japan because of the following three statements in particular.

(1) The essence of the technical presentation is described (p. 47)

- I thought about it as if I were a member of upper management. The need to put myself in the other person's shoes has become painfully apparent over the past few years as I have watched my seniors and superiors at work. Even if you think this is a good idea and make a presentation, if they don't accept it, they won't get it. You have to think carefully about the other person before you put your story together.

- The upper echelons are facing politicians who are even further above them. I thought that they might want equipment as a card to play for this purpose. What weapons do we have against people who don't know much about defense but who offer opinions and encouragement?

- What exactly would that be like? I began to write in my notebook and arrange the characteristics of people I didn't understand well.

- I wondered about men and summarized what they say when someone who doesn't know better takes an interest in something outside their expertise.

- The first question is, "How much is this? The next question was, "What do you use this for?

- Men would start saying things in a know-it-all way. (omitted). Anyway, if these two points are strong, I feel that I can make the upper class think that this research is worthwhile.

- First, price; second, novelty. That's what I wrote in my notebook.

(2) (One of) the national policies is described (p. 249).

- So, could I use other countries as battlefields to keep Japan out of the war? It was a difficult question for the engineers.

- I don't know how it will ultimately be used, and if I quit only, the others will do something about it, and I don't know if upper management is even thinking about that in the first place.

- I developed a new idea where "Mametan" supports other "Mametan." Since group stupidity manifests itself in route fixation, if there is a certain probability of Mametans performing supportive actions and fixated movements now, stupidity will be reduced!

- In a country, it is better to have people with various opinions and arguments, and it is better to have multiple patterns in Mametan so they are not ultimately stupid.

- Countries become stupid when they start going blindly forward as one.

(3) The "peace" specific to our country's circumstances is described (p. 250).

- "If Japan becomes a military power, that would be a problem for the Americans. The Americans would not want to see the return of the Japanese empire. Peace is the best way to prevent that from happening. As long as there is peace, Japan will not strengthen its military. Besides, some circumstances are unique to Japan."

- "Japan is not accustomed to war deaths. It has a declining birthrate and an aging population, just like China and Korea, but Japan has suffered few war deaths since the war. This is where those who do not wish Japan to enter the war can turn to for help. Politicians, leftists, and perhaps even China, South Korea, and North Korea."

- I thought Japan's peace constitution was why it did not go to war. However, I also believed that the deterrent power of the Constitution might be just that.

The above may be a very "spoiler" statement.

I have taken care not to deviate from the scope of "Quotation (Article 32 of the Copyright Law)" as stated in the Copyright Handbook of the Agency for Cultural Affairs, but if I receive a complaint from Mr. Yuuri Shibamura or anyone else involved in publishing, I will immediately delete the article.

-----

Now, the book ends with an actual battle scene with "Mametan," in which the amazing "combat capability" of the distributed and cooperative robotic weapon is fully demonstrated.

What gave me chills was when Robot A measured the sniper target's position and Robot B made a long-range (2km) snipe shot from out of sight.

Even from my perspective as a researcher of distributed cooperative networks, this sniping seemed "entirely possible shortly.

-----

Incidentally, these "Mametan" seem to be mass-produced by the company I work for and Mitsubishi.

I was convinced that my company and Mitsubishi were the only two companies that could develop this robot, and that factory was the only one that could do it.

I have been fed up with the publishers' weak attitude of changing the newspaper's name from Yomiuri Shimbun or Asahi Shimbun to Yominichi Shimbun or Asauri Shimbun to get away with their deceptions. So I thought,

"I felt very comfortable with the fact that they properly disclosed the name of the company."

I don't know what the company's upper management thinks, but we are not a small-ass company that would be bothered by something like this. No problem.

My company is so generous as to let me go free, to begin with.
