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).

Udemy:Good for self learning

2018/6/13. Udemy: Good for self learning 

These days, I am using Udemy, online movies site for self learning. 

This online movie site is very good for self learning.
Honestly, I could release my first app for this site. I learned about Swift AR kit.
And Udemy has app for smart phones, so wherever I am, I can learn by movies.
1 course cost approximately ¥1300($12).
Real price is higher than it, but Udemy also do sales in low prices.
Maybe the price will be higher when Udemy becomes famous. 
So if I learn by self, using Udemy is good.


And learning by movies is better than books. And books cost equal to Udemy.

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!!!
