Speaking of Kyoto Animation Co.,I've quoted it many times so far, "Hyuka" is great.

However, as I still think, high school students who can guide "Hyouka" → "Ice cream" → "I scream" do not really exist.

-----

Speaking of Kyoto Animation Co.,I've quoted it many times so far, "Violet Evergarden" is great.

No matter what aspect you cut, the artistic beauty,like works in museum, overwhelms other works.

-----

Speaking of Kyoto Animation Co.,I've never quoted, but "Fullmetal panic" is great.

I don't really like fighting robots, but this is an exception.

-----

Speaking of Kyoto Animation Co.,I've never quoted, but "Amagi Brilliant Park" is great.

I think it is a work that gives me the illusion that I could understand the amusement park customers, operations, and management.

"vi" is a text editor that comes standard in almost all operating systems, except Windows.

Therefore, as long as you can use vi, you can do the least building, operating and maintaining systems.

However, vi is also notoriously difficult to understand and use.

Of course, it's also true that once you use it, there is no tool more useful than this, and it still has power users.

# By the way, I also have a total of 4 vi operations that I can use.

About a year ago, I was in the process of transferring the technology of an application I had created on Raspberry pi to an internal business unit.

There were five members gathered there, including engineers in their 20s, 30s, and 40s, and the head of the department.

I was working on transferring the application to a Raspberry pi, which was brought in by the division, and giving a lecture on it.

I also had to rewrite the build information to make it more consistent with the network environment and other factors.

-----

It is the "manager" of the department, who understood my lecture deeply, and pointed out the errors in my operating procedures, was

When I was working on it, and just muttering to myself

Ebata: "Oh, shit! Didn't have "emacs" on it. "vi" isn't good for me"

the general manager said

"I'll rewrite it by "vi".

I was surprised when he offered to do so

Aside from skills of the general manager.

"All engineers in their twenties, thirties, and forties kept silent"

was that. I thought,

"It's like they've never even touched a UNIX command before"

Well, if you're a user of the system, I think it's safe to say "UNIX? What's that?"

But as an engineer who builds systems and provides services, I have to ask myself, "Is that really good enough?

I'm not sure I can judge it either -- maybe it's just "old man's blabbermouth".

Nevertheless, what I can say clearly is "If you can't use UNIX (Linux) commands, you can't run Raspberry pi".

Incidentally, my companay motto is "Contribute to society through technology".

It would not be an exaggeration to say that this is the only link between the company and me.

Just the fact that my home network stops working is enough to make my 'heart skip a beat'.

This is because a network failure will cause a complete shutdown of the business, and there will be no way to notify others.

And today, it happened.

Nowadays, I can't imagine my life (work, entertainment, etc.) without the Internet, so it's very scary when I encounter such accident.

This time, I'm glad I only had to "reboot," but "rebooting" has a pretty high probability of "failing."

If the reboot fails, all functions, even those that were partially working, will be stopped.

Therefore, it takes courage to press the "Reboot" button.

-- Really, I can't tell you how many dozens of systems I've crashed by pressing "reboot" (distant memory).

-----

Once you have successfully "rebooted," it is important to print out all of your configuration information soon.

This is because it is a sign of a full-blown failure.

It is unfortunate that I have to admit this, but it is the information printed on "paper" that comes into play at the last minute.

This is because digital data cannot be retrieved when the system dies.

-----

I have now uploaded hard copies of the configuration information for my home router to the cloud from one end to the other.

In my case, I often forget where my "paper" is, so I let them escape to the cloud for now, and find peace of mind.

However, even the cloud goes down when it goes down, right?

-----

For electricity, water, gas, water leaks, clogged pipes, etc., there are places (maintenance services) to cry to, but I wonder if there are places to cry to for this kind of home network.

I hope I just don't know -- if the network goes down for a whole day, it could easily kill me (and my work).

I do not have the ability to 'understand formulas as they are'.

Basically, I can finally 'feel like I understand' by applying numerical values to those formulas and turning them into numbers and figures.

No... to be precise, not even "figures" -- I feel like I finally understand it when I drop it into figures related to my immediate surroundings.

In search of a concrete example of the above model, I listened to a lecture at an Indian university on YouTube last night, took down the specific numbers, and dropped them into Excel.

I was finally relieved when I saw the graphs.

-----

Or, about the following formula,

I wanted to get an idea of what it would be like to incorporate mathematical formulas into a program without understanding them, because it would be terrible later on.

However, since this formula has two input variables, it must be displayed in three dimensions, but Excel does not have enough variety in the three-dimensional display.

I was wondering what to do and then I remembered "Gnuplot".

I ran it for the first time in several years and got this figure with one equation line (zero preconfiguration).

I was moved again with saying "Gunplot is great"

With the widespread use of smartphones, various daily lives of civilians are being filmed, which are then aired as "compilation programs" on television and other media.

This is fun enough with content alone.

Comments from studio guests -- I don't want any.

Quiz-style guest answers -- not at all, no need.

I "skip" all those parts.

Well, this is a matter of my taste, and some people say, 'I need guests.

----

I think the "ratings" system needs to be rethought.

Recently, they have also been measuring the ratings of recorded programs (time-shift ratings), but it seems far from a fully automated system.

It is relatively easy to install on a device (TV or HDD recorder), such as measuring "commercial skips."

This could be applied to measure guest comment skips, etc.

But, this system does not seem to be in place.

Well, I understand why.

If "commercial skipping" and "comment skipping" become available, (1) sponsors' willingness to invest in TV programs will decrease dramatically, (2) TV stations' revenues will also decrease dramatically, (3) TV personalities will no longer be used, and as a result, (4) the number of contents viewers can choose from will also decrease dramatically.

Because it would be a realistic reenactment of the "Tragedy of the Commons" or the "Prisoner's Dilemma."

The optimal strategy that does not break this framework would be personally doing "commercial skipping" and "comment removal."

-----

Incidentally, a popular TV drama series was cheating with a "top rating of over 40%," and I was muttering to myself, "Talk nonsense.

By examining the number of people traveling during the public transportation period, it is easy to see that this "40%" is impossible.

I would like to know the definition of "ratings."
