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

University education

2018/7/27.  University education: There are some future problems…

Recently, I am learning English & programming by Udemy, online education system.
Not in courge… And not by professors.
No matter which Udemy’s teachers have Dr. or not, the reputation by customers are decided.

Online education kills university systems, I think.

University systems cost a lot of money, the salary for teachers, assistants, and professers.
In addition, the research equipments are expensive.
So students pay expensive fee for them by education loans.

University has 2 or more functions, education and research.
But online education takes place in former function.
And university education costs cheap, but it is paid a lot, I mean it is CASH COW for university.

If university loses their cash cow, what is left in it?
High salary and pension.

Now university has brand names, but those values are bubble.

The values will falls sooner or later…

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!!!
