I am moving my blog from blogger to amazon AWS. This is NEW site URL: http://www.creating-favorite-opinions-kouhei.net Maybe I will write only to this site. I haven't got https URL yet, so smartphones are not suitable devices...

2018/10/19.  Python or PHP Python or PHP… Which one should I learn for next programming language? This is difficult question… I will learn PHP in school , but IT trend is Python… Simple question , what do I want to do by them? Making assistant tools for stock investment… ( I don ’ t know which is better for it… ) Maybe Python is the answer. I am afraid of wasting time for learning… But they are similar language , so learning both of them is not wasted time.

2018/10/16.  Tools named motivations: Do you sell or buy them? This is criticism to the coaching… Do we really need motivations? If so , we try to do wrong things… Coaching is the method which sells motivations to others. These motivations are like mandrils in gold rush era. We use them for success. Success is just like gold. Almost all people try to get gold , but I think this gold is like bitcoin , it will disappear in soon.  We don ’ t have to get the success which is determined by coaching. Because the success is illusion. And coaching , this is the system of “ Ponzi scheme ” . Coaching will erase the pains of others in one time , but not forever. I have 3 or more choices to be happy. ( 1 ) Know the system , and ride it like a small rat. ( 2 ) Know the system , and get off the society rules. ( 3 ) Know the system , and make the system. Maybe I can do ( 1 ) and ( 2 ) . I can write about the motivations in Medium site. And I writ...

2018/10/13.  Solar panels:Where did our tax go? Solar energy is illusion. This is the system which is made by sands. Some of us have dream that we can use light energy better. But if we convert light to electric energy , there must be conversion loss. Conversion loss will be thermal energy. When green plants use light , they generate oxygen. But when we use light as energy , we generate small electric energy and thermal energy. We are one of crews in the earth , not top , I think.  Solar power system generate one more thing for us , money flow. Our tax are used for solar power system as assistant payment. When company sell solar electric power , government buy it by fixed price. The fixed price is standing on assistant payment. And solar panels… This is standing on simple scientific principles. Of course , if we want to understand these principles deeply , it is difficult. But the principles are simple.  So making solar panels doe...

2018/10/10.  Facebook: Big data stalker? Simple question… Do we like Facebook or not? I am not prefer Facebook , but I am using it unwillingly. Because Japan Mensa recommend using Facebook. This is one reason , and just only one. I am thinking about Facebook ’ s real purpose. And it wants to collect user information with real name. But I don ’ t want to cooperate to it , and I don ’ t need to. So satisfaction from using Facebook is very low ,   but risk of using it is very high. Is this good for me?  Maybe I don ’ t need Facebook , and I will stop using someday. 2018/9/30.  Facebook: Risky information bank Banks have to make their security so much. But how about information banks? They seem to have weak security. And I remember the news that “ millennial persons don ’ t care about their information to be used by company ” . Is this real? I think that this news is fake or advertisement. I rethink about SNS ’ s pur...

2018/10/8.  vs China: Solar Power Energy ; BIG illusion My opinions about solar power energy are below. ( 1 ) Solar Power Energy is not worth economic. ( 2 ) High efficiency solar panel is BIG illusion. ( 3 ) Only China companies earn money from other governments ’ money. ( 1 ) Solar Power Energy is not worth economic. Solar power energy can ’ t continue without government ’ s assistance payment. Of course , other energy also need that money , but solar power energy only generate low voltage energy and high costs. ( 2 ) High efficiency solar panel is BIG illusion. I know high efficiency solar panel is big illusion. The voltage is limited from solar light , this is from physical principles. So if we need high voltage energy , the panel have to be connected in parallels. This causes energy loss. And how about high efficiency solar panels? There are high efficiency solar panels , but the number of high efficiency is under 20% from so...

2018/10/5.  iPhone security: How to improve it? I am not security professional about iOS or macOS. But iOS is not secure OS , because it is too convenient… Too convenient means it is not high security. So I stopped about something on iOS. ( 1 ) Bluetooth in public space:Bluetooth has security holes. So it ’ s not good in public space. I usually use bluetooth for my headphone… ( T_T ) But I will stop it in public spaces… This may be not important... ( 2 ) Air Drop:This is dangerous. Because someone can send you files by Air Play. ( 3 ) Memo text:I have written blogs by iOS ’ memo. But I deleted them all from iOS…

2018/10/5. Resources of Earth: 80/20 rules  We human use resources of earth. The populations of human are about 7 billion people. When the numbers of resources which we can use in a year , is 100 ( Normalization:Scientific method ), how are 100 resources distributed? I think the 80/20 rules is applied. In fact , 80 resources are distributed to the 20% people ( 80/20 class ) . And 20 resources are distributed to the 80% people ( 20/80 class ) . So there are 2 classes , 80/20 class & 20/80 class. Further more , how many people can enter the 80/20 class? Human populations are 7 billion. So 20% is 1.4 billion. 1.4 billion people... This population is as same as population of China country. If China becomes king in the world , no other country can be 80/20% class.

2018/10/4.  Russia aims to focus on west sides… A Russia-Japan Peace Treaty? https://nationalinterest.org/feature/russia-japan-peace-treaty-32197 Japan and Russia have long history… I know that when Russia wants to focus on one side , Russia wants to make peace treaty with another side. So if Russia wants to make Peace Treaty with Japan , Russia wants to focus on west sides. Russia will focus on Middle East ( Iran , Syria ) and East sides of EU. This is experience from Japan history…
