I do not remember "When I was on dating, I had a problem with topics".

It might just be "no memory", and moreover, the number of dates of mine, might be also very small. It happened to have been so.

-----

Even now, my wife said,

"Why can you talk so much in the middle of the night, after you worked harder and tired in your company?"

Even if she says "Why", I do not understand well either.

The reason might be, I work quietly at my office. or laboratory alone all day.

I am quite talkative, so I know I should not criticize other's talks;

Nevertheless, as an engineer of information systems, I come to get angry with conversations that do not utilize the communication resources.

------

There was a young lady speaking by smart-phone in a conversation mode, in a Yokohama municipal subway train.

The voice of a man, heard from a smart-phone probably was her lover.

Male: "Hey, where are you now?"

Female: "Where do you think it is?"

Male: "Yeah, I do not know at all. Where are you? "

Female: "Where am I (with smiling)?"

------

Taking up the lady's smart-phone,

"It is a point about 20 seconds remaining until the municipal subway Shonan-dai. She will get off soon!"

I wanted to shout out loudly to the smart-phone (just I thought)

"Do not crush precious communication resources (frequency channel, communication band) with conversation with zero information!"

I thought that.

------

I know well that

I was wrong.

I am an IT engineer, however, I have never used "Data-Base" since now.

Basically, I have been an engineer for control system, so I try to make a system just using ordinary system memory for super-high speed and super-small capacity.

Even for a simulator for of 100 million persons, I want to operate the simulation, not using DB HDD, SSD, but just ordinary system memory.

-----

This time, with several reasons, I have to use "SQL DB". To tell you the truth, I was surprised that

"What is on earth, this convenience device?"

(Incidently, I am using a DB whose name is PostgresSQL.)

While writing one million data, I can read data (Of course, I can use an ordinary system memory but I also make other mechanisms like threads, information protect, and open/close files).

Especially, the grammar of SQL message are usable viscerally.

I don't know how to work a DB, however the speed of search is surprisingly fast. The DB can display the information of specific person from data of 600,000 person.

(To be continued)

(To be continued)

I have used the tool that can operate from one hundred million ten hundred million lines (Of course, it was tremendous tools , I think). On the other hand, it is like

"A super-cool secretary stands by me"

I am afraid that I have not known this useful tool before.

-----

In fact the result of today's topic is not the above.

I am a man who

can neither criticize nor evaluate what I don't know, but

come to make a noise "It is great! it is great!" once I like that.

In conclusion, I am really an ungentle

You can call me a "contemptible person"

(Continuation from yesterday)

To tell you the truth, a real fear of the influenza is that "you can heal naturally about for a week, even if you feel pain and fatigue.

Those people (including me) will be a distributor of the "influenza type B"

-----

I heard some stories from my wife and daughter.

- The students of the first line of desks in a class, came to be off sick, by a teacher who was a source of the disease.

- Teachers who were worry about the delay of program, tried to attend the class, and the school was pushed into "temporary closing of school".

According to "influenza type B" of this year, I think that the above stories is believable.

-----

This "influenza type B" is approaching you, acting "playboys" or "playgirls".

You should be wary of deception.

Recently, I read an information magazine for group companies at the corner for coffee-breaks.

In that magazine, the dialogue between a marriage consultant(woman) and a consultant (man) was described.

-----

Woman: "Well, let's first go on a diet"

-----

Yes, she is right.

If you lose weight, you can become beautiful.

If you are careful about anorexia, diet is the best cosmetic method for both men and women.

For appearance, there are (violent) effects that can not compare any expensive cosmetics.

-----

I can agree that that it is important, of course, to "increase intelligence," "acquire cultural knowledge," "have confidence in yourself," "active something others depend on you".

But for "romance" "marriage" strategy, -- Unfortunately -- the top of the action list is "diet".

I think that many people use the word of "horizontal expansion" easily.

"Horizontal expansion" is to expand the existing technologies or know-hows to another objects.

The motivation of "horizontal expansion" is, honestly speaking,

a hope to "take it easy", "bargain for it", and "finish it quickly"

and to realize them.

-----

"Horizontal expansion" is also attractive for executive officers.

Above all, it is a magic word that just one investment can make a lot of acceptances of order after that.

However, "horizontal expansion" will not work well in many cases.

For not only heterogeneous business(goods and services), but also homogeneous, it is not easy.

As far as "horizontal expansion", to start making scratch might be cheaper.

(To be continued)

(Continuation from yesterday)

Question: Why can Ebata be able to say such a thing to confidence?

Answer: You only need to find out how many books hit the keyword "horizontal expansion" at Amazon.com

-----

Still, if you still can not convince, let's show the following example.

There are two daughters, the eldest daughter and the second daughter in our house.

Both of us are growing up healthy - really, I can appreciate something (God?).

Both of the two daughters are "human beings" and "women". And the age difference is only three years.

So,

If I am asked whether I can do "horizontal expansion" about care know-how between the eldest daughter and the second daughter

I can say immediately on the spot,

"No way"

Last night, I asked my wife about this matter. She said 'Roughly 80%'. about the difference.

In conclusion, we can assert that they are completely separated and original systems, that cannot apply to "horizontal expansion".

(To be continued)

(Continuation from yesterday)

The difference between products and service systems is even greater than the difference between my two daughters.

(Incidentally, the wife was surprised to hear my opinion, and said "Is not the system smaller than the difference?")

People who say "horizontal expansion" comfortably for the system,

"do not know what is "system""

I think so.

(But I do not say anymore, because I am a hired engineer).

-----

By the way, in interpretation of patent law, "technology" is

(1) Means for achieving a specific purpose

and

(2) Things that can be communicated to a third party

in addition,

(3) not "skill" that depends on the characteristics (ability, sense or can) of the individual

It is clearly stipulated.

(In the lecture of the patent law, at the very first lesson, "what "technology" is")

"Horizontal expansion" is not "technology".

In addition, is not even "skill".

-----

"Horizontal expansion" is

(1) not be able to be inherited as things like "design drawing" of goods or service model,

(2) to remain only as a "thought" for a person who "designed" it,

(3) something that is implicitly intellectual, personally exclusive and can not be inherited

-----

""Horizontal expansion" will not succeed if we make a specific person a vehicle"

I am afraid that there are too many people who do not understand this.

(But I do not say anymore, because I am a hired engineer).

I always use a watch, ""CASIO Watch WAVE CEPTOR Radio Watch MULTI BAND 5 Digital Model WV-58J-1AJF for Mens".

After examining past history at Amazon, I have already bought three same watches.

One for my father, the others for myself, the junction of the band has already been lost.

Taking it to the watch shop, the clerk tells me "it is cheaper to purchase than to repair". Unfortunately, it is true.

So, I purchased bonded parts (180 yen for 10 pieces) at Amazon, and forcibly join the band with glue.

Recently, the two batteries have run out of batteries in a row.(It was reset on January 1, 2005, and no display came out at all)

When the battery runs out, I was planning to replace it.

The cost of replacing the batteries is also a reasonable amount(Especially when maintaining the waterproof treatment, it also becomes "it is cheaper to purchase than to repair".

-----

Costly, it is correct behavior to discard these watches and purchase new items, In other words, such actions will also contribute to the economy of the Japanese economy.

But these watches were

fainting on hunger.

(To be continued)

(Continuation from yesterday)

Just because food costs are high, we discard people who have been indebted for many years as garbage. This is not for humanism but for IoT engineer.

So, this time - "I thought I'd try to replace battery by myself".

Even if I fail to replace the battery and destroy my watch, this is my "gratitude" for my watch that I have taken care of for a long time.

-----

I bought a battery (143 yen) at Amazon.com and attempted to change the battery by watching the video on YouTube.

I could not replace it as I expected.

I pulled the metal fitting almost, forcibly pull out the battery, and inserted a new battery.

-----

The two clocks are moving cheerfully now.

They can receive the radio waves everyday and adjust the correct time. the backlight also flashes properly, and the alarm sound is clear.

Both of them did considerably unreasonable in this battery exchange, so it may not do well,

In this way, the watch I have fixed by oneself is many times "cute" than a watch that I have not.

Yesterday, I was watching New Year's cards arriving in this New Year, I noticed but the number had definitely decreased.

Of course, I also gradually reduce the New Year's cards I posted, so I do not feel anything unexpected.

I can say one thing, I feel that

"Everyone might start to close the connection of their life"

In the communication program, it is very important to close all of the communication connections even when the program terminates abnormally.

In order to avoid wasteful consumption of communication resources, or maintain confidentiality as well, "disconnecting" is important.

-----

Of course, human relationship is not a communication program, so I know it should not be said as such a rough story.

"I want to stay a connection with someone, I want someone to remember me forever"

To hope it - Of course, it is no problem to hope it - is useless.

Because we forget people who have disappeared and we come to live every day.

So, in the same way, I think that living everyday to make me forget perfectly is important.

-----

However, since I change my opinion easily, tentatively, this is my today's personal impression.

Also, regarding New Year's cards, it might not "closing of connections of life". It may just be that they come to feel "bothersome" like me.

Well, everyone has their own life.

I have been crazy for a programming for a few months.

However, I have left a lot of document works, so I had to stop the programming.

For a few days, I wrote and wrote documents, and I noticed that there are two types fatigue.

-----

I realize that the overloads of brain are different,

In case of the coding, I have to chase more than 1 million's object at the same time, so I am exhausted when going home.

In case of the writing, I have to make a story with a reasonable logic. Even if one collapse of the logic happens, I have to make another collapse in order to fix the previous collapse. That is a negative catenation, so called. Anyway I have been under a lot of stress.

Both of them are not "easy".

However my ultimate hope is "to live my life easily".

Of course, I want "money" and "honor", however I can exchange them with "easy" for me.

However, when we want to become a "easy" master, I think that I will lose not only "money" and "honor" but also "my favorite works". So it is difficult for me.

(To be continued)

(Continuation from yesterday)

By the way, there is worth listening to a story that retired or terminal people said

"I should not have worked harder, while be working"

We have already experimented on the several scenes in my life.

Especially we adults, know well that

"There is no meaningless relationships with friends of teenage era in our life"

However we, as working people, cannot say

"There is no meaningless hierarchical relation in our company"

We can forecast the future after our retire, but we cannot act to ignore the hierarchical relation because of worry and fear.

-----

In conclusion, we can "take our life easy" but we don't have courage to "take our life easy" in a specific field and time.

After all, I think that we will

"regret our extreme worry and fear, at the time of retirement or end-of-life"

When I heard that my senior daughter had a date to Tokyo SkyTree, in spite of myself, I said

"Lovers are inclined to go high"

I also went to a bar and drink with my wife at the top floor of the highest building in Osaka. (After that, I moved to a pub at the underground of the building and had grilled chicken.)

Ebata:"There is a proverb of "smoke and foolish person are inclined to go high", so "Lovers become foolish accidentally" might be true."

Senior D:"as I recall, there used be a Twitter's comment of "When the Christmas comes, lovers are crowd around illuminated places. Are they insects?"

Ebata:"I thinks the lovers should become foolish insects. The time we become "foolish insect" is shorter in their life"

After hearing it, My wife said with admiration

Wife:"You tell a lot"

Ebata:"I talk about "love" enthusiastically."

Senior D:"I know. and it is long"

Junior D:"Repetitive"

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 ?

I heard a teacher makes students make "soldering iron" at my daughter's school.

"The teacher of your school is stupid ?"

Accidently, I said such a line from my mouth.

-----

"Soldering iron" is a device that melts metal "solder" and electrically connects electricity and electronic parts. However it is a dangerous device that generates high temperature.

Except for engineers like myself (I have a degree in "electrical engineering"),I do not know how many people know the existence of "soldering iron".

More than that, the use of "home made soldering iron" is itself dangerous. I will let my daughter purchase mass commercial products with safety standards and teach how to use "soldering iron".

I let me make "drivers" at my junior high school, and we could buy "driver" at the 100 yen shop.

If I says, my own behavior ("self-made love") will also be denied, but still there should be a priority.

----

This priority should be done in technology and home economics classes.

(1) Cooking: Based on rice and miso soup, it is enough to tell two kinds of fried foods, simmered foods and pottery items with the rest of the ingredients.

(2) Sewing: Basic knowledge on repairing of broken parts, broken parts.

(3) Woodworking: Easy loading platform, bookshelf, shelves to make on the wall. It is sufficient to designate the dimensions in the DIY shop and cut it for wooden boards, in addition, how to use woodworking bonds and electric drivers.

After that, how to locate the main plug when the water pipe ruptures, how to contact when gas leaks etc.

-----

Basically,

"Acquisition of technology to live alone"

is important.

Technical home economics classes are no longer a practical study, beyond other subjects.

That is how to make "soldering iron" (How to use)? What on earth are you thinking?

Even my electrical engineer I cannot understand the reasons at all.

I thought that "are they really stupid?" I examined it properly - and I was surprised by the surprising fact.

(Continuation from yesterday)

(Continuation from yesterday)

In "Junior High School Study Instructor's Commentary Techniques / Home"(Ministry of Education, Culture, Sports, Science and Technology, July 2008) on p.27., there is a description of "soldering iron".

"The level that the state is requesting the citizens (children)" was surprisingly high.

Cooking, sewing and woodworking are naturally written, and furthermore, regarding the significance of "soldering iron", the following issues are described clearly.

(1) Learn about the function of current limiter, earth leakage circuit breaker etc. indoors

(2) Learn about the mechanism of using electrical equipment safely

(3) Learn to (a)prevent accidents such as equipment damage and electric shock due to electric leakage,(b) need Maintenance and inspection to continuously demonstrate the performance of the equipment in the best condition, through examining, the devices and examples of accidents caused by electrical equipment

-----

In a word, that means,

"Even if the problem of electricity at home happens, you can fix it yourself"

-----

The Ministry of Education, Culture, Sports, Science and Technology said "Cooking"," Clothes", and "Do-it-yourself" ar not enough".

One step is "soldering iron".

So I will withdraw my opinion of "The teacher of your school is stupid ?", and apologize to the teacher.

Both the Ministry of Education, Culture, Sports, Science and Technology and the teacher in the field, understand that what they have been doing properly.

-----

And I will tell youth

Government of our country - "they are pretty tough"

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

Let's turn the world by "Number" : Work style reform(6) "

Governments and companies that confront with "side work" What are the benefits to workers?

-----

My junior of my company took a big bite out of my this column.

To: my junior daughter: Read the last sentence in the last page, and give me your impression.

That's all

I enjoy an animation, whose title is "Yuru-camp"(means, "loose camping")

The reason is

When I was young at the same age of the girl heroines, I had dome same types of camping (in fact, I think my camping was harder than them)

However, I am really afraid that "camping in winter" will let them die.

-----

In my case,

- I was almost frozen to death, even in spring camping.

- A radio program of Aum Shinrikyo(before terror attack) frightened me to death.

- A snow avalanche that blocked a forest road, compelled me more than 50 km reroute

- I was washed away by the high waves near the sea.

-----

"Where is Yuru-camp ?"

I repeatedly asked myself the same question unconsciously

"Hard camping", "Tough camping" or "Solid camping"

are suitable for my early days.

-----

I think that I repeated punitive activites when I was young.

"What did I want when I was young?" I don't know it at all by now.

You may know that I continue to make several kinds of "simulator" on a day-to-day basis.

Basically, I like to make simulation programs. Moreover I am a

"Native speaker of C/C++ (program) language.

even if the language has a bad reputation,

If there is a nation whose name is "C/C++ kingdom", I believe firmly that I don't have to worry about communication in the nation.

I don't need any illustrative sentence book and sightseeing brochure.

Above all, I feel proud that I am one of wise old mans who can use "ancient spell language" that enables me to touch a computer operating system directly, with some system calls.

-----

However, I am afraid that the words of "I like simulations" means, on the contrary, "I dislike mathematical model".

The other days, I wrote a story that my simulations duration became zero, by a mathematical model that a reader presented to me.

My enforced simulations (which use a lot of random numbers and objects) are

more "ugly and awful"

than mathematical models( based on statistic and differential equation)

Of course, it was true that the performance of computers of old was too poor to do the "enforced simulations"

So, we have always needed more computer performance, especially in the field of physical science, for example, magnetic, electric and weather analysis, there is no reason that we don't need any more performance.

(To be continued)

(Continuation from yesterday)

By the way, a personal computer(PC) has enabled us to calculate behaviors of all people in Japan using virtual objects. I am afraid that

"the face will increase the pressure for the person in human science field"

Before it was enough that

My hypothesis -> objective data or my logic -> my validation

However, now, I think that they should add the following activities, and

My hypothesis -> objective data or my logic -> numerical simulation or mathematical model -> my validation

they will not avoid mathematical processes.

Researchers with majors in the school of humanities, should produce simulation programs in large quantities. It is realistic future, I think.

-----

Hereinafter, private communication from me

to my daughters

- Your father can teach programming to you.

- I am going to adjust to "Ancient spell language(C/C++), let's ask me an advice.

- If you don't have proper motivative example and problems, I will farm out to you.

- Before due date, I will pay for money.

The feeling that "the world is in this hand of me!" ss a pleasant sensation that I can not taste in daily life.

"fork()" is one of the greatest APIs (in other words "paradigm") that were designed and built at Berkeley in the 1970's.

I hope that I am a first person in the world

who tried to use the API for "time leap" between two different "world line"

in paralell virtual worlds in my PC.

(As far as I know, nobody has used this API like the above case)

-----

Refer to

"See this code, if you want to realize "time leap" or "reading steiner" in your computer"

Additions: Okabe's "reading steiner" functions are omitted, because information of his memory will be send by pipe() or external files.

I like making something by myself" that is called "DIY".

The reason is that I am a hunks rather than a creator.

The main reason of the persistence of "DIY" is for a satisfaction that I can save money.

For example, I can make a PC desk by one cheap veneer board, and install local area network at home by myself. All of racks in my house were made by me.

-----

By the way.

Recently, I know that EtherCAT slave base which can be installed in Raspberry PI is sold for 6000 yen.

at a country in Europe

No matter where it is sold, of course, I want to get it. However the total cost (including shipping) become more than 24,000 Yen. So I had to give up.

I also tried to check the cost by my company system, the price come to be same.

I hope that I want to make the cheapest EtherCAT slaves, based on Raspberry PI by DIY, But this is meaningless for this cost.

-----

Of course, If I start to study about the hardware design and production now, I will make it. However, I had run away from the hardware technologies because the design and trial was always annoying me when I was a college student.

Well, I think that this though was not wrong.

Thanks to enormous performance of microcomputer IC, many technologies has been realize by software(like farm ware and operating system)

-----

However, EtherCAT realizes "Zero buffer transmission" which is ultimate realtime communication

No matter how hard it can be done with software, software cannot realize beyond the performance of hardware.

I like "DIY" for everything, however, the cost for "DIY" is more than a thousand times than commercial products. it will get my priorities wrong.

-----

So, (this is very rare for myself because I adhere to individual activities, however) is there anyone who made your own EtherCAT slave for Raspberry PI?

Let's join me.

I think that I can introduce the place for presenting the results - probably

The other day, my senior daughter joined a market for figure dolls ,like "comike", on the side

Checking in on the day before, she worked at information desk for the event.

However, I thought the first person who would try to join an event like that, is either junior daughter or me.

Junior daughter will be a seller of her "illustrations" or "comics".

I will be a seller of my columns or be a news reporter

-----

As a result, senior daughter's comike debut was beyond us.

The other day, when I was examining the patent system in my company, numbers of my patent applications were displayed, and it was just 100.

To tell the truth, the number includes applications I was not the lead inventor, I think that the lead invention of me will be reduced by 20%.

However, in many applications, I have experimented to give me some rare notices of reasons for rejection others have not.

Most reasons for refusal are violations of inventive step (Article 29, paragraph 2), executable requirements (36), violations of unity (37). In addition to the violation of novelty (Article 29 (1)) and the earlier application (Article 39), I have gotten great things called "public order and morality violation".

"Some examiners of the patent office surely knows my name"

I think it as my pleases.

-----

I had heard the story that "there is a "notice of allowance" without notice of reasons for refusal" on the grapevine.

Of course, I did not believe it.

(To be continued)

(Continuation from yesterday)

In order to get "notice of allowance"

A inventor (or an applicant) and an examiner at Patent Agency,

fight for exchanging of cannonball by "notice of reasons for rejection" as a declaration of war

and continue intelligent battles to get border line of the patent right severely by correction and limitation repeatedly

Finally, they are going to reach a compromise -- I have taken it for granted that the above scenario.

-----

However, I could get "notice of allowance" without "notice of reasons for refusal", and I was very surprised at this fact.

I have never experienced in this administrative decision before, and it paniced me seriously.

What is this keen uneasy feeling ?

My heart was tight with fear, if the examiners at Patent Agency come to think "we tired to play with Ebata by his logic"

Recently I have to read about AI technologies and economics, however in the book and Web site, I can find

"few table and figure".

This fact surprises me and annoy me.

Tables and figures are very convenience, because they can explain many things that are almost equal to 100 lines articles.

However, I feel ... how to say ... authors of the book and site, seems to stick not to use tables and figures.

I am not familiar with the pubbery, but I wonder if there is a custom or a culture of

"No life with tables or figures"

-----

I read the phrase "20% readers give up reading by reading each one formula"

This means, just five formulas in a book vanish all readers.. if you think "Ebata tells a lie", you are a person of "no problem about formulas".

"The numbers of reader who can think "initial readers x (0.8)^N (N=1,2,..N: numbers of formula)"

The person who can think the above at sight, can finish reading the book.

I am afraid that the readers are awful few.

At any rate, I think that the ratio of Japanese people in the science and engineering majors, is 35% (Ebata's estimation). In addition, the number who can use maths and statistics routinely is less than 10%.

-----

Thinking of it, the thought of "no life with tables or figures" is a reasonable strategy in pubbery field,

However,

If the population of the people who can use maths and statistics comfortably increases, some interesting things may happen.

If most Japanese can do a trial calculation and check the accounts by spreadsheet, most politicians and half of bureaucracy should be retired.

Well, I know that it is just a dream.
