2014-11-04 "We can work out if we can line up all words that are needed in the English conversation."

I have been opposed to starting English program at junior school.

However we cannot avoid it, I can accept the way of

"Learning only English words off by heart”

-----

The following is my absolute believe,

"We can work out if we can line up all words that are needed in the English conversation."

I believe that, moreover I know that.

In fact, I have worked my oversea tasks and I have been able to do them.

In addition, I think that my company gave the proper values for my jobs to me.

(To be continued)


2015-11-04 "The UN tried to change Japanese to English as National language in Japan, indeed."

The other day, I watch a TV program that explained about the occupation polices after WW2 had an intention of

"The UN tried to change Japanese to English as National language in Japan, indeed."

-----

The TV program said that it was based on a hypothesis that "Japanese was too difficult to understand the government policies, so Japanese must have rushed into the WW2."

After the investigation of it, they should have faced the reality of aristocracy of literacy rate in the world, so the polices were abandoned after all.

But this result is very interesting for me deeply.

We can read this fact into "Japanese might choose the war on their own will" or "espionage of the administration, army and mass-communication".

Above and beyond this.

-----

My junior daughter said strongly,

"Why did they enforce the policy of "English Language Empowerment Act" ?"

I am an guardian of Japanese people, and I think that I cannot accept her claims directly. So I tried to argue against her even if it is our stated reason.

"Well, any language is a concept of tool that can define races, and it also gives us a background of power of nation...."

Indeed, I am impressed with regrettable feeling that

"It is easy to understand patterns of thinking of children whose parent is not loved by English"


2016-11-04 Appetite, weight loss, nutritional balance. All of them should be lead to "health".

(Continuation from yesterday)

This time, I had started the strict diet control before two weeks, and I could decrease my weight with an accuracy of 0.1kg and approach the target weight.

"Re-victory of numerical diet"

I felt delight for the first time, however, I I never imagined that the luck of nutritional balance pointed a finger at me from the view of "numbers"

-----

I have continued to write in the column, the cycle of "lose weight" -> "calorie consumption is reduced" -> "sense of hunger is reduced" -> "lose weight", will be possible.

However, if caloric insufficiency reaches to the level of the brain, anorexia will be triggered soon.

To the calorie control without triggering the anorexia, the ingestion of a single food is good for the calculation. After all, the nutritional balance will be out of scope.

Appetite, weight loss, nutritional balance. All of them should be lead to "health".

(For me, the viewpoint of "beauty diet" is no longer necessary.)

-----

In conclusion,

(1) the precise biological system that this "Ebata"

(2)has been difficult to control with overall optimization, so

(3)This system has a bunch of very real problems.


2017-11-04 "Only concentrating one thing makes effectiveness or productivity" that is a sort of "accepted theory" is rejected by the Ebatas.

(Continuation from yesterday)

When I was a kid, teachers or parents blamed me for a study with watching TV. However, I don't say anything to my children.

I know well that their approaches are more effective (or productive) for them.

"Only concentrating one thing makes effectiveness or productivity" that is a sort of "accepted theory" is rejected by the Ebatas.

For a head of the Ebatas, actual performances (e.g. data) are always justice.

Though I am also studying or working with hearing music, I cannot doing with "watching movies".

About the music, I cannot accept music with lyrics, so classic and jazz is good. I also can hear animation songs.

About animation songs, my brain will skip verbalism, like "justice","evil","friendship","future","past" and "eternal", and I cannot recognize them as meaningless words.

_ -----

Now, one hypothesis of mine, which they can study and watch movies at the same time, is that

teenagers have excellent multi-tasking capabilities, and

they can control the loads of task relatively freely.

I think that they can complete to finish "new-type brain".

Anyway, we, who have just "normal power" should avoid saying this and that, to them, who have "psi power".

2018-11-04 The interface design that appears in near future SF animation is useful (Well, as "Pretty girl Android" is left aside).

I am watching science fiction animation whose stage is in the near future. The main purpose is to enjoy that content, on the other hand, they are also useful for my works.

"User interface"

-----

"User interface" is an intermediary between a machine (computer) and a human being,

On a daily basis it is a "smartphone's operation screen", and it appears in the form of "beautiful girl android" in the SF world.

The superiority of the user interface confirms the evaluation of the system, and it is no exaggeration to say that once the interface design is decided, the system requirements have been decided.

In other words, "user interface design is difficult".

-----

The interface design that appears in near future SF animation is useful (Well, as "Pretty girl Android" is left aside).

Watching these animations, I understand the feeling of animation creators, "how they understand software technologies (including AI technologies) and digital services", and I can know their the concept as a specific example.

However, my preference .., correction of animation ... Since the range of directivity is extremely narrow, I can not say that I grasped the whole SF animations. (It is not likely that I will finish my life without being called anime otaku).

Still, the following animations made a contribution to my work and make it.

- Heavy object for "visualization of AI technology"

- PSYCHO-PASS for "visualization of human psychology"

- Sword Art Online for "visualization of virtual world"

On the other hand, although it may seem surprising, the interface of such as "Space Battleship Yamato" or "Neon Genesis Evangelion" is not very useful for me.

The former, as a system concept, has an old feeling (due to the extension of the modern battleship), the latter is because I can not grasp the overall appearance of the system (system requirements).

Of course, this is my sense of interface and the sense is irrelevant to the superiority or inferior of the work (just for my preferences).

-----

By the way, the other day, I contributed on the theme "Verify the feasibility of animation AI".

If there is a chance, I'd like to consider also in terms of "verifying the effectiveness of the animation's user interface".


2019-11-04 "You shouldn't do what you like"

The strength of weekend engineers is to guarantee "delivery date, no quality guarantee".

The weakness of weekend engineers is to purchase the necessary parts at their own expense.

-----

I've made a system with Raspberry Pi and I've had many times thinking that it's "hard", "difficult", or "troublesome".

However I have never wanted to think to

"run away"

-----

I think there are various opinions and ways of thinking, but at least I think at this moment

"You shouldn't do what you like"

Well, tomorrow I may be saying something different.


2020-11-04 "However, it is regrettable to bring thousands of yen a month for AWS self-study."

(Continuation from yesterday)

"However, it is regrettable to bring thousands of yen a month for AWS self-study."

When I was thinking, I found Amazon Lightsail.

It is a server of 3.5 dollars (500 yen) / month, which is a range that can withstand even if I run out of my own stomach.

Yeah, this is good.

In the first place, I have no intention of protecting the server from external cyber attacks.

Even if the system is broken, I can't enter any information that would be a problem from the beginning, and the source code is published on github.

One core (equivalent to EC2) of the virtual server is enough, and the DB can be built in the core.

Above all, I don't want to configure the load balancer used as a firewall or Route53.

-----

So, this weekend in early November, I was repeating a "bad" test of installing a prototype server on Amazon Lightsail and continuing to attack with data of thousands of objects.

Of course, a communication failure occurred (caused), but the server did not go down. To be honest, I'm impressed with how amazing it is.

-----

So, let's get back to the beginning.

"Shifting the development direction to the home server using Raspberry Pi" is coming into scope of "using the cloud".

For 500 yen / month, I can play on a private internet server ... If I can operate it, it's enough for me.


2021-11-04 Even if we find out years later that direct exposure to radio waves in the GHz band dramatically increases cancer rates, by then it will be too late.

In our house, we currently have "five" wireless LAN access points activated.

Our house is not a huge mansion, but an ordinary single-family house.

The reason why this is happening is because my family complains to me that 'the wireless LAN is not connected.

-----

As I've explained before, I don't believe in wireless LAN communication, especially for remote work, so I use LAN cables to connect all my devices.

Wireless causes "null points," which are points where wireless radio waves interfere and disappear regardless of distance, so there are cases of transmission failure quite often.

In such a case, it would be enough to shift the location a bit or disconnect and reconnect the device, but my family, except for me, does the simplest thing without such technical devices.

"Complaining to me"

-----

I'm not in charge of managing the wireless infrastructure, and I'm not paid to do so.

Rather, I think I am providing a stable supply of a luxurious IT environment that is unthinkable in a normal Japanese home. Even so, if there is a slight problem, they will immediately complain.

This is the same way the general public deals with the businesses that maintain the infrastructure (water, gas, electricity) in Japan and around the world.

Water, gas, and electricity are, well, life-threatening infrastructures, but that's not the case with home LAN.

If they don't have a home LAN, for example, they can do by without it.

-----

So, what I did was to pull the LAN cable right up to the table and put a small wireless LAN access point right next to the kitchen table, a thorough "short distance strategy".

The distance is a little more than a meter, I think.

I already thought that this was almost like connecting a LAN cable to my phone.

If it is this close, there is no way for a null point to occur.

But well, it's like having 2.4GHz and 5GHz radio waves irradiated directly into your body.

Even if we find out years later that direct exposure to radio waves in the GHz band dramatically increases cancer rates, by then it will be too late.

But -- well, in that case, I probably won't be too disappointed, since I'll have a million or so compatriots (or hundreds of millions of compatriots around the world) with me.

I have written a similar story here.


2022-11-04 As a senior academic, I'm thinking, 'Don't we need real classroom learning anymore?' I think.

I am currently taking a classroom lecture at a university, and after all this time, I realize that 'studying was so much fun'.

I can almost hear you saying 'Huh? What are you talking about now?'

However, after working as a researcher for a long time, I have been taking in the necessary knowledge and using whatever tools (calculation methods and techniques) are available to me on a daily basis.

"Systematic study" is given "in a systematic way"

I realize how wonderful (or rather, how beautiful) it is to be able to do this.

"It will be difficult for current college students to appreciate the beauty and splendor of this place..."

I thought that.

Of course, there are still some current college students who can understand "it", but is it "senior people's assumption" that makes me think so?

-----

The problem is that the lectures are given in "English" - of course, as an "engineer who does not love English", I cannot understand the content at all.

Then, it is no longer a matter of giving up on understanding English and countering the lecture content with thorough preparation.

And now I am using "YouTube".

The lectures on "YouTube" are also in English, but I am trying to listen to whatever I can, and write about it, until I somehow "feel like I understand it".

I use the lecture offered by one of the universities in India.

The examples with real-life numbers are practical and really helpful.

I stop the lecture video in the middle of a lecture, put it back, print it out -- I am running them out.

It is definitely the "remote lectures" that have flooded YouTube with such an abundance of courses -- "I think this is also thanks to the Corona disaster.

-----

As a senior academic, I'm thinking, 'Don't we need real classroom learning anymore?' I think.


2023-11-04 Still, when I looked at the computer terminal this morning and found that the PC had found the solution -- as expected, I couldn't believe my eyes.

Since last night, I have been running a GA (Genetic Algorithm) program for a solution search of 1600 integer digits (solution combinations are 2.25x10 to the 1118th power).

As a result, this 1600-digit solution search took about 20 minutes to complete.

For me, GA is no longer a research subject.

In my mind, the phase of creating this "holy sword" called GA ended 30 years ago.

Now, I am?picking up "holy sword (=GA program)" from the net and using it in several places with appropriate modifications.

-----

However, when I started to turn the GA algorithm, I heard a strange noise that I had never heard before from the PC.

The fan starts running at full power, and the PC chassis temperature rises sharply.

It is to the point where I am afraid that my PC will break.

----

Therefore, we decided to port the program to a PC for gaming, which we had purchased as a dedicated calculation machine, to perform calculations.

As you would expect from a PC with high-performance specs.

The machine seemed to be able to solemnly perform many calculations without generating such unusual noises.

So, this time, I tried to calculate the solution with 16000 digits, ten times the number of digits of the original 1600 digits.

I couldn't calculate the solution space with my calculator, so I asked ChatGPT, and the answer was

"This is a huge number, with thousands of digits. When dealing with this number for practical purposes, we usually use logarithms and other mathematical techniques to deal with approximations and digits."

ChatGPT got away with it -- well, it is pretty common for ChatGPT to get away with it.

-----

Come to think of it, I try to keep my ChatGPT sessions going by setting the alarm to go off in 40-minute increments so that I can ask questions regularly.

So, every 40 minutes, I ask ChatGPT a trivial question.

For example, I asked ChatGPT

"List the problems that would arise if an illegal armed group were to be formed to rescue the abductees and then recapture them by force."

ChatGPT had an exemplary answer, like a government answer (try it if interested).

Now, let's return to the main subject

-----

At any rate, there is no doubt that the solution space of a 16,000-digit solution will be so large that it will transcend even the cosmic level.

I tried to force this calculation, but it could not be done in 20 minutes.

Last night, I went to bed with my computer running.

However, last night, I was awakened by a terrible noise (for about 2 seconds) from that gaming PC.

Twice, too.

The gaming PCs have also screamed," I thought.

Still, when I looked at the computer terminal this morning and found that the PC had found the solution -- as expected, I couldn't believe my eyes.

"GA is awesome."

I realized that.

Well, I am greatly helped by the fact that high-performance PCs allow me to do some pretty crazy calculations.
