2021/7/26.  The “more” or “more than or equal to” I met one difficult problem. The original story(English) is below site’s problem. And changed story(Japanese) includes changed rule. I think that this change is from mistranslation. But this change causes the problem MORE difficult. The original story http://www.bigriddles.com/riddle/ten-pirates-and-their-gold [The problem part] Each pirate will vote against a proposal if they know that they would end up with more gold if that proposal were to fail. [Changed rule] Each pirate will vote against a proposal if they know that they would end up with “more or equal to” gold if that proposal were to fail. It is a miracle difficult problem caused by mistranslation. “より大きい” corresponds to "more than". “以上” corresponds to "more than or equal to". “未満” corresponds to "less than". “以下” corresponds to "less than or equal to". In addition to the model answer, there are the following answ...

  2021/7/16.     Cheaper economy in Japan   I ate alone dinner at Yayoiken in Japan. https://www.yayoiken.com/en_files/regular_menu_pdf/88_2021.07Regular_EN_0706.pdf?id=2281 Hummm. It costed ¥780, approximately US$7.10. Is this too cheap? I ate at Tokyo Ginza in Japan. I don’t want to tell how good taste it was or how beautiful the dinner was.(And it was not so beautiful, just only one meal.) What makes it so cheap? Law of one price seems to have strong power in Japan. https://en.m.wikipedia.org/wiki/Law_of_one_price I think that law of one price prevents raising price in Japan. I want to think more deeper about this topic, later.

  2021/7/8.  “ 追い貸し” “追い貸し” refers to the extension of the life of bad company that should normally leave the market by the bank by making additional loans. Additional loans to bad company or government for extension of their life… “追い貸し” is similar to debt trap, but more clever. I feel that “追い貸し” is being done to USA government by other governments or non-native USA investors. Simply, USA government can’t return their debts, so that they have to cut government costs or USA interest rates raises. But none of them occured. This is because of “追い貸し”. “追い貸し” keeps on until USA government give up. In additional simulation, I think that next USA President will be Mr.Trump. Because if the USA stock & bond market crash, the society will be confused. At that time, he gets that position.

  2021/6/29.  The RED FLAGs in Tokyo Stock Market I sold all my stocks in Tokyo Stock Market. There seems to be some red flags in Tokyo Stock Market. First of all, J-reit market’s average Net Asset Value(NAV) is high. Almost all J-reit stocks’ NAV are over 1. This means that J-reit stocks are more expensive than their real values. Secondly, J-reit market’s average yields is 3.3%, it’s near 3%. This is dangerous flag. Aging country, especially as Japan, has low interest rates, but there are risk premiums. Risk premium has to be higher than 3.5% in Japan. (This number is what I feel.) Interest rates in Japan is under 0%, and I think it is equal to 0%. So J-reit market’s average yields should be over 3.5%. Third red flag is existence of individual investors. They are end buyers, and they seem to bet their money in Tokyo Stock Market. I don’t know when this bull market ends, but I quit this game and take a rest in some months. Cash is king, and crash is near.

  2021/6/2.  The Humanai & Humonkey I am afraid of the future between Humanai and Humonkey. Of course, Humanai and Humonkey are my original words.  Humanai The people who can create or use AI. Humanai can also use programming languages. Humonkey The people who are used by Humanai. Humonkey is monolingual, and only use smartphones. I want to write more about this topic, but I can’t write it now. I am learning about Python and other IT more and more.

  2021/5/25.  The Working Memory(WM) Working memory https://en.wikipedia.org/wiki/Working_memory Working memory(WM) is a small memory in human brain which can hold temporal information. WM is the part of short-term memory which is concerned with immediate conscious perceptual and linguistic processing. WM is just like a memory on computer. I have heard that training WM was important for doing tasks on job. Recently, I felt that I could training my WM with some smartphone’s app. And I found that N back task may be effective to train WM. N-back https://en.wikipedia.org/wiki/N-back There are some variations in N back task. I bought one app which train my WM by remembering about numbers of figure. https://apps.apple.com/jp/app/nバック/id591320567 I found that N-back task is consisted from load power and cycle number. Load power is number of N, and cycle number is number which I solved N task. Training WM is just like training muscle. Now, I could score 60 time...

 2021/5/12.  The Keynote Drawing I created one drawing. Recently, I bought electric piano (only for DTM). I am interested in creating music. And below are pictures what I have taken in Tokyo.

  2021/5/9. The Searching with Google Recently, searching with Google may be not enough for high IQ people. First of all, results of it include many advertisements, which are applied for SEO. Secondly, Google search doesn’t optimize for abstraction words. High IQ people can use both of abstract words and specific terms. If we search with specific terms, there are answers what we want to know. But if we search with abstraction words, there are mistakes. It’s not wrong for Google, because Google does business and optimization to various classes is correct answer for Google. In addition, Google seems to try other businesses, such as AI, Education and Firebase with Cloud servers. Google search may be still main business, but there are too many companies which want to cheat search rankings. I think that Google search’s results will be worse than now. And this doesn’t mean that Google’s stock price will be cheaper. Google may search other business fields(with Google search engine). :-)

  2021/5/1.     The Python I am learning about Python language with Udemy.  Dr.Angel’s “100 days of coding” is best course I have met. Python language is just like user side computer programming language. It is very useful for computer users. This means that Python language will be defect standard in programming languages. There are various computer OS, and Python will be language across those OSs. Python is powerful language. For example, I use Python library PyPDF2 for combining PDF. This library saves money for me to buy additional PDF readers’ function. The function costs $15per a month. There are lots of IDE(App for writing codes), and I am using VSCode on Windows. VSCode is free IDE for private development. Very useful, it is. If someone wants to get new skill, I recommend learning Python. And how I learn Python are below. (1)Watching Udemy courses. (2)Reading books. (3)Copying codes from Udemy courses and books. (4)Additionally, reading magazines about Python....

  2021/4/1.  The 80:20 rule I wonder that how many times I have wrote this theme. 80:20 rule This is unfair rule which is called as “Pareto principle”. https://en.wikipedia.org/wiki/Pareto_principle If this rule is applied to whole people on the earth, what happens? Certain people(20%) can use 80% of the earth’s assets, and almost people(80%) can use 20% of them. The number of whole people on the earth is 7.9 billion. 20% of 7.9billion is about 1.6billion. How big is the 1.6 billion people? Almost as same as the number of Chinese. China vs USA is simple. Which is the king?

  2021/3/7.  The CLOCK The CLOCK is my app for Kindle Fire tablet. https://www.amazon.co.jp/s?i=mobile-apps&rh=p_4%3AKouhei+Takagi&search-type=ss I released it! The app is simple clock app. It displays analog clock, current date, and digital clock.

  2021/2/20.  The intensive reading I used to prefer speed reading more than intensive reading. Intensive reading https://harappa.education/harappa-diaries/what-is-intensive-reading The meaning of intensive reading is to read with full concentration and complete focus. However, I found my intensive reading skill has been very low. I have not read books or news with much concentration. I just only read them just like computers scan them. Recently, I have been trying to pass some exams. I passed some easy exams, but I lost difficult exams. I regretted about it. I thought why I lose them, and I found that I haven’t use intensive reading. Difficult exams needs high language skills, so to pass the exams, I have to increase my intensive reading skills. Quality is more than quantity. Facebook CEO has said “Done is more than perfect.”, this is right answer for perfectionists, but I am not perfectionist. I want to say “Perfect is more than done, for me.”. I didn’...

  2021/1/10.     The Option trade   I got ¥100,000($1,000) with option trade. I have done good trade, but I am worrying about the stock markets now. The stock market is booming now. It’s not bad at all.  But it seems to be dangerous. Everybody becomes greedy, so take care! I recommend that keeping high cash position and entering into stock market with the money which you can lose. When everyone becomes greedy, it’s time to stop dancing on stock market. I have bought Gold & Silver. They are not so high prices. And I will bet my money with option trade again in near future. This site provides how market is greedy or fear. https://money.cnn.com/data/fear-and-greed/ Now it’s 77 points greedy. There may be some space to raise stock prices. But I feel something is going strange. This is because nobody can stop money financing by central banks. I guess that stock prices will get higher till July in this year. But I don’t have solid confidence. This stock market’s b...

  I am studying for being Patent Attorney, and I found below trademark was applied to Japan Patent Office, but not filed yet. https://www.j-platpat.inpit.go.jp/c1800/TR/JP-2020-137729/31C8152A1A492C98E37BACEFC31043A133B19BEE5BFABB8F34464EE83FC39CF5/40/ja “APPLE WATCH” was applied by one famous free-riding company. Apple company, take care!

In the Cold War, Russia had bigger power. Russia lost to USA without real war. Then, Japan lost to USA on economic war. USA gov controls Japan gov perfectly. In now, China tries to challenge USA. I don’t know future result of China vs USA. But USA can’t win to China without fellow. USA gov has to build the team “VS China”. China is already trying to make the team “VS USA”. The settlement will be decided until USA or China gov goes bankruptcy. Question:Which country will go bankruptcy first? USA or China? Now, I read news about China’s digital yuan. https://www.investopedia.com/understanding-chinas-digital-yuan-5090699 Recently, Crypto currency’s prices are raising. I thought that introducing digital yuan make capturing dark economy possible. Dark money is flowing to crypto currency, I think. But China gov can capture all flow of digital yuan. It means that China gov can easily increase taxes income. Because China gov can watches all money flows. Again, I ask the Question. Question:Whic...

  2020/12/27.     The Solicitation   When I was in Cafe, I saw the solicitation for automatic investment system (must be scam) between 2 young men. I watched them and found some things. (1)They were telling about FX or stock automatic investment tools. ->A lot of people are trying it with very efforts. (2)The solicitor was using tablet device, but recruited person was using paper and pencil. ->There is very big digital information difference between them. (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.

  2020/12/20.  The Box I am reading the book “The Box: How the Shipping Container Made the World Smaller and the World Economy Bigger.”. Shifting Low productive works to be higher has a lot of stories. This shifting is happening in lots places. In Japan, for example, restaurants install tablet devices instead of hiring waiters. I wrote below formula in post blog post. P = ( S - C ) / T P: Productivity S: Sale C: Cost T: Time If we want to improve productivity, we reduce cost and/or time. Cost includes labor costs. Labor cost is generally proportional to working time. New technology makes less working time possible. Then labors lose incomes. This shifting is like how knowledge is treated in our brains. If we know something, it is difficult to act as not knowing it. This shifting is irreversible. I think that this shifting is happening to everybody. For example, I am learning Python on Udemy (Online Course). This means I don’t need to go to school fo...

  2020/11/14.     The Japan society   I am thinking about Japan society’s history after WW2. Japan society has tried to catch up with developed countries. It was achieved by optimized Japan system. The word “optimization” is suitable for Japanese character. Japanese are good at optimization in closed system. It means that if there are some platforms, Japanese will try to get first rank. Optimization is effective in closed system. This is one fact, and vice versa. Closed system needs optimization. If there is optimization, there is closed system. Watching current Japan society, too much optimization are there. This is caused by closed system. There are some solutions, opening closed system, keeping closed system, and so on. Japan society has chosen about keeping closed system. This is Japanese answer. And almost all Japanese don’t want to change their society. It is one solution. (I don’t know this is right choice.) They want to keep their lives as long as they can....

2020/11/8.  The NEXT one USA president election has finished. Mr.Trump has done great works. He has showed us bad sides of current systems, Capitalism & Globalism. USA and other developed countries are aging, and this means that they are losing their power. This is clear from that they become to depend on MMT theory. Turning point is the time one developed country bankrupts. When turning point comes, aging developed countries will realize that they have to pay past generation’s debt. When and where the turning point will happen at, this is problem. Japan? USA? Italy? Or other country? I thought some situations, 1)Japan Japan is aging, and someday Japanese average workers will realize that they are paying past generation’s debt, not for their assets. At that time, they will do something bad thing to Japan government. Now, Japan gov is doing well, in other words, it is tricking average workers. Japan government’s bankruptcy will be after 2025.(This is roughly estimation.) 2)USA U...

  2020/10/24. The Abstraction   Abstraction skill is one of the most important intelligences. IQ tests on Internet often are for abstraction skill. On learning programming language, I found programming skill that it is nearly equal to abstraction skill. Recently, Japan education aims to teach this skill through programming education. This means that people will acquire not only programming skill but also abstraction skill in the future. Abstraction skill will become average skill in the future. This skill will be cheaper than now. Of course, I have to get abstraction skill more through programming & patent office’s works. But this is not good way. I think that people have to get 2 skills which earns money now, and which earns money in future. Former skill helps us to live now, latter skill helps us to live in future. And AI will acquire abstraction skill sooner or later. Are there the skills that won’t be acquired by AI? Of course, there are! AI’s skills are based on text ...
