Tiên tri xứ cát

 Tôi đọc phần 2 Dune sau 3-4 năm đọc phần 1. Đây là một trải nghiệm thú vị vì một thời gian dài tôi không đọc sách liên tục ở mức tập trung cao như vậy. Gần như - tôi đã bị mất tập trung và sao nhãng bởi mạng xã hội, những tin tức liên tục yêu cầu cập nhật và việc ngồi trên máy tính những giờ dài nhưng không làm được gì cụ thể.

Phần 2 của cuốn sách phô diễn một bi kịch của tiên tri vĩ đại: người thấy hết mọi tương lai và vì vậy sống trong quá khứ- tương lai - hiện tại cùng một lúc. Đôi lúc tôi nghĩ bi kịch của Paul là từ đạo đức của hắn nhưng thực tế là do tâm trí hữu hạn của hắn phải chịu một năng lực quá lớn.

May mắn cuối cùng của Paul lại đến từ sự giới hạn của năng lực tiên tri: Paul đã không thấy hết nên đã không hoàn toàn đau khổ, và ngẫu nhiên hay tác giả vẫn tặng một món quà đẹp cuối cùng.

What's wrong with TradingBot using AI

What's wrong with TradingBot using AI

Today, again, like another day, I read one post on X, "Guide: How to Create Your Own ClawdBot That Can Earn $1,000." The title was so confident, the profit in the picture was so attractive, and there was also an on-chain link as proof. https://polymarket.com/@0x01542a212c9696da5b409cae879143b89661




The original post was from January, so I'm really curious what's happened with that account. Follow the on-chain link, I saw a list of red loss, in one month, the bot lose 50 000 usd.



I wonder why the strategy sounded good; its results were a big pain. Another concern is why the owner let the bot trade continuously for one month, although it was totally wrong.

Those curiosities were partially satisfied when I asked Claude Sonnet to do an analysis task:

I asked Claude to collect the silver price in Vietnam and compare it with the global price. It operated smoothly and created a beautiful chart. Everything was amazing.

Just one thing, I worry about the data because in Vietnam, the data APIs are limited. So I asked Claude where it gets data from:



Then Claude confessed that it make up all that data after cannot find a good source. 🐧

crypto inheritance

Dear my crypto friends,

    Today I helped the family of a young hodler to cash out his crypto currency. Our friend passed away in his twenties, leaving his family with regret and a little crypto.

    Luckily, his younger brother knew most of his password, and we easily withdrew all the crypto to the brother's new wallet. Looking at his account, I could see a young man who lives thriftily and puts most of his money into cryptocurrency.

    The bad lifestyle may be one reason for his end. But this event reminds me about the importance of a crypto will. A special process to recover our coin when we will be gone. It must balance privacy, security, and user experience (especially for non-tech users.)

    Do you have any plans for your crypto in the worst scenario? Let's think about it, one day your family will be used. Nonetheless, no one can avoid death.

Money management

Money management


This month, my expenses skyrocketed, increasing by a staggering three hundred percent. Upon closer examination, I found that my daily expenditures remained small, with the majority of the increase coming from unforeseen payments.


Essential needs such as food, housing, or transportation only contribute a small fraction to this month's cost structure. In my past plan, I managed to tighten my budget by cooking at home and reducing unnecessary travel. This strategy effectively reduced my daily expenses by 20-30%, but It didn't significantly alter my overall financial status.


Hard times give me the ability to optimize minor expenses, and I've become adept at controlling my basic needs. However, when faced with larger payments, I found myself lacking of skills to use money effectively, although I read and knew the theory. From my viewpoint, all these expenses are necessary and cannot be reduced. 


My financial status has undergone significant changes, but I still managed it like a freshman. It's time to learn some new skills.

Blockchain active addresses

This graph demonstrates the fluctuation in the number of active addresses for Bitcoin and Ethereum, the two leading cryptocurrencies. It reveals valuable insights into the current state of the market.


Represented by the red line, Ethereum, the world computer caught up with Bitcoin in 2018,  a mere three years after its inception. Both blockchain users' numbers increased during bull runs and decreased in bear markets.


In 2023, despite the significant surge in the price of crypto assets, the active user number remained relatively stable at around 800k. This suggests there are not many new users entering this industry, the influx of capital may come from old users and some big players.

New year goal of a bookworm

 New year goal of a bookworm


In 2023, I set a singular target for myself: to read 52 books, and I surpassed it. Reading does not bring me more money or love, but this hobby gives me a lot of happiness. Therefore I spend one to two hours a day reading.


Since 2019, I have begun to make a new year goal. That year I was only able to achieve 3 out of 10 goals. So I reduce goal numbers in the subsequent years. The fewer targets, the higher the success rate, and this year, I finished 162% of my single target.


Compared to previous years, my reading list included more English and comic books. I discovered a new favorite author, Neil Gaiman, and devoured nearly all his tales, which contributed more than 50% of my 2023 bookshelf. Additionally, my collection of technical books now has more engineering, and less financial books.


For the upcoming year, I plan to slightly increase my goals. Let's see if I can achieve more than one:


- Read 52 books

- Build a snowman

- Learn a master's degree

EQ

 EQ


The emotional quotient, or EQ is a set of abilities that include understanding, expressing, controlling, and using emotions. Unlike stable scores like IQ, emotional intelligence is a dynamic skill that can be developed through learning and experience.


First of all, self-awareness is the essential step. Recognizing your feelings, understanding their origins, and accurately naming them help people gain insights into themself. A rich, detailed vocabulary can facilitate the expression of one's status more effectively.


Articulating your feelings can calm down extreme emotions, and there are several techniques to ease negative thoughts such as walking, writing, or meditating. In addition, a positive mental state can be cultivated through memory recall or body language and can be amplified through self-suggestion.


While individuals can adjust their emotions, their feelings become tools that can be utilized in various situations. Those include self-healing, self-motivation, and self-happiness. They can also be leveraged to influence others in both personal and professional relationships.


To conclude, emotional intelligence is a vital skill that requires continuous improvement for a more fulfilling life and successful career.
