When I was a junior-high or high school student, there are comics and animations, of course.

They also have been now, and I can access the media from my daughters.

I have had one question since from my earlier years.

"Could junior-high or high school students drink "cafe au lait" at cafe?"

Thought I can admit that the scene seems to be beautiful, it is high-flying.

If trying to drink at a cafe, we have to spend more than 400 yen.

In those days, I had to pay more than 550 yen at McDonald, having hamburger and drink only.

"Could they order the expensive drink usually?"

In all ages, I have felt heavy difference about their economical situation of person in comics and animations.

-----

Especially, I strongly think that there is no way that two high-schoolboys drink coffee at caf?.

I want to ask them

"You should sit at counter of Yoshinoya's beef bowl."

Even if it is girl's romance comic, I want it to keep this reality this much.

Well, I agree that the readers don't like the scene.

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

"A nonfiction story of online fraud (the 1st part)"

"The day when "a network researcher" encountered a cyberscam"

-----

Reading the manuscript of 26 pages of whole story in 15 minutes,

Saying "Ebata-san! I could tell you nothing! I am impressed!!"

The junior fellow who had started to talk about his fraud accident in Europe,

has existed.

In the Ebata's all home electric appliances and other devices are my slaves.

I can control them at my will and even if they go out of order, I almost can fix them by pincers, drivers, tester and copper bit.

On the other hand, all members of the Ebata's except for my, are salves for all home electric appliances and other devices.

They are going to give up easily against troubles of doorknob, hinge and exchange of light bulb and battery in the end.

-----

One day, my wife called me in my office, and asked me to go back home immediately, saying "I will pick you up at the station by car". I was pale and asked her the reason, she said,

"The PC cannot show Japanese characters on the display"

I shouted "Try Google search!"

She said "I cannot do it without Japanese"

Well, it was reasonable. The PC was wrong.

I got mad with someone who makes the ridiculous design that "Not returning the initial status, even after rebooting.

I think "to return the PC status for Japanese after rebooting, because the PC is in Japan".

Yesterday, I wrote that "not to use a PC" is same as "not to use a pen", however, I sometimes come to think that "a PC is inferior to a pen".

(To be continued)

(Continuation from yesterday)

The total amount of things she lost was too big, so it was impossible to be recovered by the above (1) (2), however, these two are only solutions she left in her hand.

"Sunk-Cost Fallacy" might be not enough for her tragedy.

-----

By the way, even if we overcome "Sunk-Cost Fallacy", another problem will happen in another place next time.

For example, it is a daily routine that, "a work that I have worked on for years by pouring my heart is abandoned by senior management."

Or, it is the case that "I was removed from work that I managed to keep on track, and was ordered to launch another project"

If these things continues, nobody will think that "trying hard" is worth.

On the contrary, "hard working eventually will be a "loss" and we are going to be cynical about any working.

-----

So, let's try a reverse thinking.

(To be continued)

(Continuation from yesterday)

Certainly, smarphones are not only communication devices but

- ticket-vending machines of Shinkanse super express,

- windows to submit some papers to a city hall,

- conference rooms to arrange with neighbors

- communicators to inform our location if an emergency arises

The breakdown of smartphones, is going to be an crucial trouble in our life, not exaggerated.

If a window of a major carrier in any station, will guarantee "safety and security", My wife's thought is reasonable right.

I am an expert who is familiar with communication and electrical equipment and services. Therefore , I think that I cannot understand "my wife's fear" from the bottom of my heart.

-----

Then I will return to the original story.

Aside from smartphones, I am an amateur about inheritance, insurance and financing.

Ultimately, I need somewhere to cry out "do something for me" and to run away.

Even if "block chains" guarantee transactional safety and legal inheritance relationships, I can not believe that "block chain" can help me, who is just crying.

-----

So, I think, for the phrase of

"At this rate, banks will be taken over by an application of smartphones.

I don't know whether I can agree with the writer, or not.

(Continuation from yesterday)

I told you the story that,

The government don't have to give Japanese makers poor money for studies of auto driving. It is absolutely very helpful to use the fund for compensation for victims.

However I have not heard this story yet.

-----

In short, this story will indicate that

"It is bad to let people drive still

will be a punchline.

-----

Human beings have only experienced moving speeds of about 1 meter per second (3.6 km / h) in daily life for the past 100,000 years.

Thousands of years ago, it became possible to experience about 10m per second using horses, however, it is a little less than an hour of movement by only a few people (such as soldiers).

To begin with, it is quite insane that humans control high-speed movement (120 km / h) that passes through the 10th floor of an apartment (30 m) just in 1 second.

(By the way, even if you fall freely (eg jumping suicide), it takes 2.47 seconds from the 10th floor of the apartment)

First of all, driving on such a highway, where such high-speed control continues for hours, is wrong.

------

If most people are in such an extraordinary situation, it may be unavoidable that a certain number of "incompetent guy" occur, such as "tailgating", however,

There is no reason we allow "incompetent guy's performance" of the "incompetent guy".

I, basically, do not believe in the goodness of man.

I feel like my axis is more on the side of "Junkyo" than "Mengzi".

At the same time, I know that this isn't an "either/or" thing.

In short, this is based on an individual's vision (values).

Because the world can be seen differently depending on where we are at (time, place, environment, past experiences, etc.).

-----

However, even then, I sometimes believe that "human beings are good as they are born."

For example,

$ git clone https://github.com/GuyBrand/WssSample
Cloning into 'WssSample'...
remote: Enumerating objects: 16, done.
remote: Counting objects: 100% (16/16), done.
remote: Compressing objects: 100% (15/15), done.

Unpacking objects: 100% (16/16), 8.69 KiB | 67.00 KiB/s, done.

It is the time when I am full of euphoria by seeing the output result.

-----

When I knew someone who would like to release this kind of sample program to the world, where I was struggling all day with Golang's websocket wss support ---

That fact alone makes me think, "I can believe in the world."

The day after the second dose of the Moderna vaccine, my senior daughter came out of her room in the early afternoon, feeling dizzy.

I followed her down to the kitchen and asked her a lot of questions, and she 'scolded me'.

Afterwards, I was ordered to go to the supermarket to buy some additional fruit.

Today, she seems to be sleeping and waking up all day long.

She looks like a "full combo" too.

My future predictions has been out of mark dynamically.

So I am sorry that you don't have to believe what Ebata says no much from the bottom of my heart,

And I'm going to say this with an evasive answer.

"I think robotic caregiving is a no-go (at least in my phase)"

However it is the case of "full humanoid robot", on the other hand, I think that "powered suite" has a little hopes.

-----

The paradigm that has shocked me recently is 'macho caregiving'.

"IT, control, and robot are meaningless. The 'macho caregiving' is right answer".

I was so shocked that I was hit over the head.

Through the death of my father and mother, the caregiving phase is going to move to my wife and me.

For the preparation, we will need money and devices, however, for the side of the caring , "macho" is easy to understand and a cheaper strategy.

From the viewpoint of risk management to avoid being a care receiver, this is a good approach.

-----

This paradigm has come to me, since I made the following device.

Now I can do 20 sneaky pull-ups and keep my body hanging over 60 seconds.

These days, I have added new menus for full body exercise.

"It might be not too late"

So, I am organizing a tour of gyms and other facilities for muscle training.

-----

However, \20K yen/month is too expensive for me.

Ordinal fitness club has many members, and the civic exercise center is far from my house.

My motivation of muscle training is just for "caregiving".

I have never wanted to have a macho body and be popular with the woman at all in my life.

(To begin with, I thought "Macho is stupid" that is terrible prejudice. Now I change my mind to "respect" or "useful")

In addition, I am a "recluse lover".

-----

So, I am searching how to get muscle to move a person, and avoid "strained back" just in my house.

Like the the above "iron bar", I love DIY making or modifying my house, so I appreciate if you give me some advices.

Thank you for your help in advance.

Can you guess what this is?

This is an instrument for network measurement.

I had done analog measurements because of the hassle of a dedicated measurement system.

To put it bluntly, network measurement across multiple systems is quite cumbersome.

Creating an automated experimental system, however, is even more cumbersome.

In this experiment, the camera was illuminated with LED lights, and the time it took to be displayed was measured with a stopwatch.

And now, when I counted the total number of experiments, it was over 2,000 -- I ran out of spirit.

-----

Automation" has its own set of risks.

(1) In the middle of an experiment, not realizing that there are unnecessary experimental items, one goes through hell in the tallying process of many experimental results.

(2) Experiment automation leads to many unnecessary experiments, all of which end up in the trash.

like that.

If experiments are not conducted considering the balance between analog and digital, cost, and risk -- you may end up in a bad situation.
