Correlation between NASDAQ price, Corn and Gold(Corr=0.945)

 I wrote Python code which shows Correlation between NASDAQ price, Corn and Gold(Corr=0.945). Corn and Gold are best mix I have found. https://gist.github.com/Kouhei-Takagi/a1a9b073f6cd6dacb7eb1ea871d8fd3c I changed some important parts. https://gist.github.com/Kouhei-Takagi/5becaf7c3a24d63ac9c56856e81297f2

Problems for improving programming skill

2019/3/30.  Problems for improving programming skill

I am learning Swift & Python language.
To improve my skills, it is necessary  to write the code more and more.

But these days, I don’t have enough time to write the code. 
Full time job makes it difficult. And writing the code needs much power.

My each purposes for learning programming are:
Swift is for iOS/macOS apps.
Python is for security tools.

Now Swift experience is 1 and half year.
And the result is below.

I think this result is not so bad. My Swift skill level is not beginner.
Maybe it is low-middle or middle class.
And I will learn core data, WebAPI and coreML for next subjects.
Problem is that I can’t make my apps for the side job because it is forbidden.
I care it and I will make macOS apps. And I will upload my macOS apps on GitHub.

But Python language… This is not good. I can’t use it well.
The reason is that I don’t use much time for it. 
Python is great language. It’s one fact. But I think it is too useful.
Python is like English in the world natural languages. It will be common.
I should learn it sooner or later.
Problem is that I don’t have enough time to learn both of Swift & Python.
It’s too much heavy.

I want to focus on Swift or Python. But I can’t decide my mind…


I feel this problem is happy problem. Because I couldn’t write code in 2 years ago.

Cheaper work

2016/12/29. Cheaper works: Hard competition makes expensive work cheaper. In Japan, there are some people who thinks there are a lot of workers, and they are exchangeable easily. This thought can't stand on human populations decreasing society. And in this society, the flow that provides products cheaper and cheaper cannot keep. Now, Japanese society is standing on that thought, and Japanese system hardly stands. This is by the patience of Japanese. When the breaking point of Japanese system comes, the counter of patience will keeps long time. And I think that communism never comes in Japan. Because Karl Marx doesn't think about human populations decreasing...

None feedback

2016/12/29. None feedback from others in Japanese company Feedback is not always visible or sound , especially the fact of feedback is hidden by various suits. And in Japanese company, I often see the scene that ignorance to the people who did careless mistakes. Others don't say anything about the careless mistakes in front of the person, but in background, others speak ill of the person. This is none feedback. None feedback from others is very bad feedback, but in Japanese company, it is often. Why none feedback happens? In my experience, there are some reasons. When the person who made mistakes is upper than others, others want the person to fall out. When the person is equal level to others, others want the person not to promote. When the person is lower level, others want to make the person the targets for inner circle. I rethink that none feedback in company is bad signal for organization... None feedback happens when the company is bad statements!!!
