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…

2018/9/27.  Security for macOS by free! I am learning Linux server in school. I apply it for improving macOS security. First , I choose security and privacy. And next turn on firewall. In addition , choose the stealth mode in firewall option , too. This option improve your Mac security!

2018/9/27.  LPIC Level1 It ’ s too early to take the exam… I feel that I can ’ t pass the exam…

2018/9/25.  Killing method in Japan ( Opinion ) In Tokyo , Japan , there are a lot of suicides. But are they really suicides? I don ’ t think so! Suicide in Japan https://en.wikipedia.org/wiki/Suicide_in_Japan There may be a lot of killing which are faked as suicides or accidents. For example , Monday Train suicides! They includes a lot of killings. If some people or groups want to push one person into the train to kill ,   the accident will be treated as suicide! Japanese train platforms are so  small , and if eyewitnesses are offenders or members of offenders , the murder will be suicide!

2018/9/23. Who is free-rider on global economy? Free rider problem  https://en.m.wikipedia.org/wiki/Free-rider_problem There are a lot of problems in global economy , but the business players should understand the public rules.  If some players break the rules and take profits. It ’ s not fair.  Further , if the rule-breakers act like the winner , what should other players behave?  “ Being Hunters ” is one answer.

2018/9/18. World economy:Like before storm weather  Fear & Greed index is 66 point. But news are telling about Lehman shocked at 10 years ago. I feel accidents will happen in the beginning of 2019 , not 2018. Last stock price going up will happen in 2018. But I don ’ t invest stock now. I think gold & silver ETF investment is good judgement. 

2018/9/16. LPIC Level1 101:Practice exam  I did practice exam of LPIC Level 1 101. The score was not enough to pass. I didn ’ t remember about Linux system devices & install package systems. I need more effort to pass the exam.  I will take real exam in 1-2 weeks.  LPIC exam has 3 grades , and level 1 is very basic. But the exam areas are so wide. Maybe it takes 2 months to pass the level 2. My goal is taking LPIC level3 303 ( security ), and I hope I can get them & new job! In Japan , there is similar exam “ Linuc ” . It was made by Japanese companies. So it is not useful in foreign countries. I think that there are some reasons to make it. But I don ’ t need it.

2018/9/12. Thinking about competition  What ’ s competition for? Some will say that it provides good future. Of course , it ’ s true. But I don ’ t want to join competition for someone ’ s good future , and I don ’ t need to make someone ’ s good future. I know this is free rider ’ s thinking. This is because there is lack of community minds. Lack of community minds may lead us being free riders. So politics will stop it by being conservative. Is this property methods? It ’ s not truly solution. We need another political & society system , and we have to rebuild them including IT technology. If we don ’ t , Classic systems suffer us till the limit. And Japan society is on testing it now. Change own system or be more conservative. Japan chose latter. So classic system suffers Japanese till the limit.  #I don ’ t want to wait till the end. Portable skills ( Skill:Earning money ) are needed. I need English language skill , programming & Linux...

2018/9/11. Internet:Just like stock investment (Value vs Price) Internet is important , the values are great. But recently , the reliability is getting lower. This is caused by increasing opinions , not facts. The numbers of facts are fixed , but the numbers of opinions are variable. And increasing of participants to the internet is the reason. This phenomenon is just like stock investment. Stocks ’ value is slightly variable , but their price is very variable. There will be internet in the future , but opinions should be deleted by somehow. If we don ’ t do so , the value of internet will be decreased. In the future , we will need secure , closed & paid internet.  ( Now internet is free , open & free. ) And next Internet will be smaller & wider ( global ), but more powerful. Maybe it will be kings ’ one. Or already there is.

2018/9/10. Monday comes... LPIC ( Linux qualification ) is little difficult... It may take 2 more week for having enough skill. I used to look basic test not as important. But the way is over. Basic test is important.  I stop making apps & studying Swift language. I want to focus on Linux servers.  This week plan: -Complete studying basic Linux  -Start being ready for LPIC 101 & 102 -Touch Ubuntu OS PC ( Already installed ) Monday comes... I know I am little tired.

2018/9/8. Very hard week... I am learning about Linux in the school from this week. It was very hard. I want to get qualification about Linux ( LPIC level 1 & 2 ) in 3 months. Learning Linux is fun , but the qualifications looks little difficult. I should study hard! In addition , I bought a gold coin. I ’ ll continue to buy gold.

2018/9/2. Iran vs USA There is conflict between Iran and USA... I went to Iran culture center in Tokyo. And I met some Iran people with Japan Mensa group. ( 1 ) Nuclear power Iran people told that USA did propaganda a lot. And the reason why Iran country develops nuclear power is that if Iran can ’ t use nuclear as electric power , their economies will decline. I feel this is not right. Because nuclear electric power is not economic. So there is another reason for nuclear power , maybe for weapons. I don ’ t know the relationship between North Korea and Iran. But maybe there is. ( 2 ) France  Iran people have good relationships with France. I didn ’ t know it.  ( 3 ) Politics  Iran has democratic government , and it seems to control government well. Iran people can choose their president by election. But maybe females can ’ t be president. It ’ s normal in Asia. ( 4 ) History  Iran has long history , it is over 7000years! It ’...

2018/8/31 Why did I want success? I read one Medium blog , and realized the reason why I wanted success. Lack of confidence is it! Having confidence was/is difficult task for me. When I lost confidence , I wanted success. This is from some minds. 1 ) Revenge mind: to someone or something  2 ) Anger: to myself  3 ) Pride: I couldn ’ t admit my fault  4 ) Pride: I could do better  Having these minds is normal action , but I was caught by them too much. I needed success for protecting my minds. But what is confidence? There are some answers , but I think it is something which makes people strong. If confidence is weak , people seems weak. So confidence may be relatively thing , not absolutely thing. And it is decided by relationship between people and people , or people and problems. Confidence is decided by power relationships. People who has strong confidence , may prefer to bury others. ( I don ’ t need such confidence. )   ...

2018/8/29. AWS I ’ ll go to Linux school from next week... I will learn about Linux servers for 3 months.  I think this school doesn ’ t help my job. But I go to school for my hobby. I am interested in AWS ( Amazon web service ) . AWS is main for future servers. I want my own server , but it ’ s difficult only by myself. And home servers has some risks and needs costs. Future plans ( Hobby & Small incomes ) 1 ) Web game on AWS 2 ) iOS/macOS app with AWS 3 ) Automatic investment systems on AWS These 3 plans needs knowledge of Linux servers. And I read about Java language news. Java language will be paid language. I didn ’ t know it , so I thought learning Java was good choice. I was wrong... And learning Swift language first is right judgement.

2018/8/27.  Difficult to make 3rd app… It ’ s difficult to make my 3rd app. Because I lost passion for iOS apps. And my interest moves to PHP ( Server side programming language ) . Swift is good language for perfect beginners. I learned a lot from it. But it ’ s for iOS/macOS only. I need another computer language. PHP is popular language for Web service. I feel small fear for my future. But now is the rest time for my life. I have 3 projects ( I decided them by myself ) for the future.  1 ) Being Japanese/English bilingual.  2 ) Being computer programmer. 3 ) Being investor. Each projects ’ goal is earning money wherever I live in.  Project 1 ) is good processing. I started this  from 3 years ago. I got 720 points in English test TOEIC. It ’ s not so high as native English ( 900- ) user , but I got higher score than last time. This result shows very good. Maybe this project needs 2 more years. Project 2 ) is beginn...

2018/8/21. English , programming & investment:What to learn Learning English ( or another language for natives ) stimulates my brain a lot. And English skill helped my previous job. Also it helps when I am making iPhone ’ s apps and studying investment. And being Japanese & English bilingual seems smart. Programming skill is very useful for thinking. It helps me to think as flowing. And making app is simply fun. Investment will be important incomes and assets. And learning investment helps watching newspapers from another viewpoint.
