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

Focusing on making APP, not learning Swift (Diary)

2017/11/14.  There are many things to learn Swift programming!

I realized that I don’t really understand after only reading textbooks. 
I made 3 steps for learning Swift.

Step1 Reading textbook
Step2 Typing on Xcode
Step3 Understanding the textbook

The cycle of Step1-3 must be faster!
And I believe that I will earn by my own APP in near future.
(I wonder if I have high IQ or not… What I feel difficult is low possibility for APP what I want to make. )

I want to make tools which are useful in my work.
Perhaps, I can start making my first APP from now…
My purpose is making APP, not learning Swift language deeply. I will start making my first APP in few week.

What the difficult things in programming is things what I can’t see the goals. But it’s natural. Because getting better programming skills has no end as same as English skill. 
So it is better for me to make small goals in programming.

I focused on learning, but it is better that focusing on making.

Focusing on making APP seems to the answer.

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!!!
