20190601 - Cheap solar panel and battery will change the world

After watching the video above, I realized that cheap solar panel and battery will change the world.

If the energy price is cheap enough (and no extra green gas is generated), farmers can use it to grow plants for whole year.

Potato, etc. can save human kind from famine.

The four levels of reading

1. Excerpt Good words resonate. When that happens, we are deeply moved. However, when was asked "What does this chapter say?", many people's mind get lost. "Well, it's about religion/education/war..." OMG 2. Summary In addition to flashing words and sentences, this level has been able to quickly identify the central point of the article. At this level, the book is understood. However, when was asked "What did you learn from this book?", many people's mind get lost again. "What did I learn? Well, I'm not sure." 3. Study In this level, you can clearly compare the content of the book with your own knowledge system and incorporate it into your own perception. In this way, the book will not be easily forgotten. However, a few years later, if you ask him/her: "Two years ago, you mentioned that book was very good and you learned a lot from it. What do you think the content of that book has had on you in the past two years?" ...

Book: 20250602 to 20250625, "Die With Zero" by Bill Perkins

20250603 - 1 Optimize Your Life No, you cannot get me to work two hours just to buy that shirt! p11 It's natural to be thrifty if income is low. Many psychological studies have shown that spending money on experience makes us happier than spending money on things. p13 Why? It force us to pay attention to the moment. If we can pay attention to the moment all the time, then we stop living on autopilot. From big data training point of view, that means we will not treat daily activities as noise but real data. 20250604 - 2 Invest in Experiences The main idea here is that your life is the sum of your experiences. p22 It's wrong. Based on the book "Think, fast and slow", we only remember the peak points and the end. So we should not pay much attention to general experiences. I realized that you retire on your memories. p23 This is against "live in the moment", which doesn't rely on our memories. We don't need great memory to stay happy after retirement. By...

Why I believe in DogeCoin

We heard the news that El Salvador choose BitCoin as their fiat currency. Unfortunately this is going to fail, because BitCoin transaction is too slow and too expensive. DogeCoin version 1.21 is going to drastically reduce the transaction time and cost soon. That's exciting. Two obvious questions here. 1. Why other crypto coins don't do the same improvement? Because DogeCoin is going to sacrifice one core principle a bit: decentralized structure. This is unforgivable SIN to most of the Blockchain experts, but I like the idea. Of course decentralized structure is still there, but if my understanding is correct, there will be less major nodes on the chain network. Then it will be much eaiser for governments to monitor the DogeCoin transactions. Is this good? Absolutely, in my opinion, because, countries like El Salvador can use it! All shops and people can use it! At the moment, DogeCoin can handle around 40 transactions per second (thanks for LiteCoin and Scrypt), and the transa...
