Java & Swift

2018/6/10. Java & Swift

I have learned Swift Programming Language. It’s suitable for beginners of programming, but return from Swift may lower than I expected... I was wrong about this issue, what language I should learn.

Android phones’ share may be over 70%, but it’s 40-50% in Japan. So I misunderstood that learning how to make iPhone app is useful skill in the world. But in the world, Java programming language is standard in smartphones, and it will be kept.

There is another problem about app making. Long & difficult review for iPhone app, this is heavy problem. If I want to release 3 or 4 apps, it takes time more than android apps. I know this review is necessary for brand name “Apple”. 

Learning cost of Swift is very low, so Swift is good for initial programming language. And return from Java programming, is better than Swift.


And I want to add one thing, programming for smart phones is easy to understand what I am learning. Because device is my hands, and testing original app on my iPhone is very easy. So I can see the programming results soon. This is big impact on learning. PDCA cycle is shorter.

Emotional stress is happened from the misunderstanding how others see me. Misunderstanding is happened between how I see myself and how others see me. So improving emotional reaction is to know how ot...

(3)The solicitor told that this tools would bring money forever. ->100% scam. —>The result from (1)(2)(3), I thought that the scam is happened when there is information difference. Thinking about solicitation, we have to rethink if we are hunter or food.

Own view to World and I

  Own view to World and I I thought about feeling method about world and I. The principle questions are “What is the World?”, “Who am I?”. There are several feelings about these questions’ answers. View to World and I I am [ positive ] I am [ normal ] I am [ negative ] World is [ positive ] Normal A Mismatch B1 Mismatch C World is [ normal ] Positive thinking Normal B Negative thinking World is [ negative ] Mismatch A Mismatch B2 Normal C I categorized the answers in above matrix. If “World is [negative]” and “I am [normal]” is the answer, Mismatch B2 is my position. Then if we want to change something, we should change view to the world or I.

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...
