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 ...

  2020/9/21.  The Taking a rest(More than courage to quit) If someone start doing something without thinking about it deeply, they don’t have courage to quit something. The courage to quit is more important than the courage to start. People often think quitting something is negative thing. There is the words, “Sunk cost”. https://en.wikipedia.org/wiki/Sunk_cost People often don’t want to pay sunk cost. For example, something is learning programming language. If people start it, the decision’s cost most include money, time and energy for it. More cost people paid, more sunk cost is there. If we begin not to pay additional cost about it, what can we do? Stop it? Less time for it? Quit it? I prefer to use this words, “Taking a rest about it”. Quitting it perfectly robs possibility in future. Stopping it sounds negative. But taking a rest sounds balanced position. If you don’t want to pay sunk cost or have courage to quit, I hope you to take a rest about it. ...

  2020/9/19.     The Language(English & Chinese) I work in patent office, and the language of patents will be 2 kinds, English and Chinese. Patents are similar to science papers. Almost science papers are written by English. But the patents about Artificial Intelligence written by Chinese are increasing rapidly. The problem is that the scientists who use English often can’t read Chinese, but the Chinese scientists can read English. This causes the asymmetry of scientific information. To solve this problem, Language translation methods have to be developed sooner.

2020/9/13. The 3R wasting time [Reduce, Reuse, Recycle our wasting time] A: Reduce; Reduce our wasting time. B: Reuse; Reuse our wasting time for other purposes. Having some purposes to one action/time. C: Recycle; Cut our wasting time to some parts. Minimize our wasting time. A: Reduce Our wasting time is the time which doesn’t leave something good experience for our future.  In other word, it doesn’t useful for our life.  For example, watching TV or Youtube, fighting to other people, and so on. Reduce the time is very important. But be careful that we don’t like blank time.  We have to find other useful things instead of wasting time. We reduce wasting time for something good. It may be impossible for us to reduce our wasting time for nothing. B: Reuse Reuse our wasting time means having other purposes in one time/action. In other words, it is having more than 1 purposes when we do something. For example, I listen to the music when I am walking. This action has mor...

  2020/9/12.  The Lie Telling a lie is a trick that can only be done by looking down at the other person’s intelligence. This is the opinion from Quora@Japan. https://jp.quora.com/製作側が激推ししたのにユーザーに嫌われまくった I think that this opinion is true. When I told a lie, I have looked down other person’s intelligence. I sometimes feel regret about it. If someone tells a lie, he/she looks down to others. This phenomenon is everywhere in internet world and real world. One control method is using words intelligent level. Some people understand abstract words, but some people only understand concrete words. This difference is words intelligent levels. Fighting happens in same intelligent level. So some intelligent people manipulate others to fight each other. (Just like Republican vs Democrat.) How about education? Education is done for what? I hope people wake their original talents up. But government doesn’t want to do it. I don’t care about whether current education ...

2020/9/6.   The Softbank (Gamma Squeeze) Guilty, the Softbank is. I read this news, and I feel so at the first. https://www.ft.com/content/75587aa6-1f1f-4e9d-b334-3ff866753fa2 I don’t know the Softbank intended to make gamma squeeze. Gamma Squeeze: https://realinvestmentadvice.com/negative-gamma-and-the-demise-of-optionsellers-com/ On my understand, Gamma Squeeze method makes arbitrage traders buying stocks. This is nearly crime as market manipulation crime. Then I rethink about Softbank’s action. This is similar to Japan’s Bubble Burst by Foreign investors. At it, they shot Nikkei Features by option trading. I don’t know Softbank’s action is revenge from past. The man who hits others has to be prepared to be hit. This is one rule. If the Nasdaq index goes higher, Softbank will get profit and stock of USA’s IT sections. If the Nasdaq index goes lower, the President Trump may not be next president. Hummm… Softbank is advance corp fro...

2020/8/30.  The Fire (Greece vs Turkey) I saw the news that the pressure between Greece and Turkey is increasing. But is it real? I searched it by Google Trends. The interests are: Greece:62 Turkey:7 UK:16 Some Africa countries:11 to 30 USA:4 Russia:Under 1 Hummm. I am interested in this trend. USA and UK may be Greece side. And Russia and Turkey may be same side, but not interested in this news. I believe that I am not conspiracy theorist. But UK people are interested in the pressure between Greece and Turkey. What by and for? I don’t hove opinion about this trend. But there is my opinion. Greece people seems to see the turkey as enemy, but Turkey people doesn’t seem not to see the Greece as enemy. And I wonder this pressure become the fire for WW3. I don’t know the future. But I believe that I don’t buy Turkey’s currency by FX. It is too risky.
