Wuling Motors has a concept model that changes the “Hongguang mini EV” into a six-wheeled minivan, equipped with a very mini body. Although it may not be practical, it looks quite cute. Unfortunately, it is only a prototype and it is not certain whether it will be put into production. ( via )
Non-linear world, linear you
Naval Ravikant is an American venture capitalist who has written a series of articles “How to Get Rich” and is very famous.
His articles were later collected and published and became a bestseller. It has been introduced in China. The Chinese title is “The Navarre Book: A Guide to Wealth and Happiness”, and it was listed as the “No. 1 Business Management Book in 2022” on Douban.
The weekly excerpted many of his remarks, which were very enlightening. I put them together for everyone to take a look at.
If you know how to both manufacture and sell, you are invincible. (Issue 94)
Be careful, a taste of freedom may cost you your job. (Issue 105)
The key to getting rich is to find the point where the three intersections of “individual-market-product” intersect. (Issue 107)
Do what you love until you love doing it. (Issue 184)
If you are original, you can avoid competition. Basically, if you’re competing with someone else, it’s because you’re doing the same thing. (Issue 258)
Today I want to share an interview he did last year with Joe Rogan, the most popular podcast host in the United States.
He said something that was thought-provoking.
“A common mistake for new entrepreneurs is to think that the results are predictable. If I work hard for a long time, I should get something.”
“The truth is, your results are unpredictable. It doesn’t matter how hard you work, it matters what you do, who you work with, and where you work. “
What he means is that many people have a misunderstanding: they believe that “effort” and “results” are directly proportional . The harder you work, the more likely you are to obtain good results.
In fact, this is not the case at all. There is no necessary relationship between effort and results.
“You see every day that those who make the most money don’t work long hours at all. And gold diggers and shop owners work hard all day and make little money. “
The reason is that the real world is non-linear and non-causal , while human thinking is linear and causal, and will unknowingly interpret non-linear relationships from a single linear factor.
For example, bank deposits are linear, the more deposits, the more interest; stocks are non-linear, more investments may result in greater returns or greater losses. We should not apply the logic of deposits to non-linear systems such as the stock market.
Will your continued efforts to increase your efforts, long hours of overtime, and no personal life lead to success? Probably not, since there is no causal relationship between the two.
Navarre’s advice is:
“What matters is not how hard you work, but choosing your jobs, people, and projects carefully.”
“The truly effective way to work is not to compete with who can last longer in a triathlon or marathon, but to sprint when the opportunity comes and pay attention to health and rest.”
“Be like a lion, which leaps up when it sees its prey, and not like an ox, which toils from morning till night.”
Technology trends
Goldwind Technology’s GWH252-16MW is the world’s largest offshore wind turbine, with a blade length of 123 meters and a hub height of nearly 50 stories.
It was installed off the coast of Pingtan, Fujian, and recently set a world record for power generation.
On September 1, Typhoon Haikui approached Fujian, which enabled the wind turbine to generate 384,100 kWh of electricity in one day, enough to power 170,000 households, creating the world’s largest single wind turbine.
This reminds us that although typhoons cause huge damage, they also bring huge energy. It would be great if all of it could be used for wind power generation.
A Dutch startup company has invented a “plantable coffin” that can be planted in the ground like seeds and is very environmentally friendly.
The outer shell of this coffin is made of vegetable fiber, and the inside is covered with mushroom mycelium. After being buried in the ground for one and a half months, it will degrade and germinate.
Its price is currently 995 euros.
3. Subsidies for pedestrians and bicycles
Norway has the highest proportion of electric vehicles in the world, with more than 65% of new vehicles sold every year being electric vehicles.
There used to be many subsidies for buying electric cars, such as tax exemptions and free parking fees. Now, the Norwegian government has announced that all these subsidies will be cancelled, and will instead be subsidized for pedestrians and bicycles.
In the future, if you choose to cycle or walk instead of driving, the government will provide incentives. Because more and more people realize that the way to protect the environment is not to drive an electric car, but to drive less.
Many service establishments in the United States, such as bakeries, coffee shops and gyms, require tips to reward the waiters or store owners.
After these stores switch to self-service payment, there will be no tip income. The store felt that there was a loss, so it added a page to the self-service payment machine. After the user paid, it would pop up and ask for a tip (pictured above).
This incident caused media discussion. If it is self-service, is tipping reasonable? In the age of automation, tipping should probably disappear.

On September 5, Galaxy Power, a private rocket company in Beijing, successfully launched a rocket in the sea near Haiyang, Shandong Province, setting a record for the successful launch of a rocket at sea by a Chinese private enterprise.
Haiyang has built a sea rocket launch base, and watching rocket launches has become a local tourist program.
2. Red Sea Dam
The Red Sea is a long and narrow bay sandwiched between the Arabian Peninsula and Africa. The northern end is the Suez Canal, and the southern end connects to the Gulf of Aden. The outlet is extremely narrow, only 29 kilometers.
Someone proposed a crazy plan: to build a dam at the southern outlet of the Red Sea, called the “Red Sea Dam”, to prevent the Indian Ocean from flowing into the Red Sea.
Due to the local desert climate and very high temperatures, natural evaporation will quickly lower the level of the Red Sea inside the dam. According to calculations, the water level drops by approximately 2.1 meters per year.
This creates a water level difference between the inside and outside of the dam, and seawater from the external Gulf of Aden pours into the Red Sea, driving turbines to generate electricity, potentially generating 50 gigawatts of hydropower. By comparison, the largest nuclear power plant in the United States has an output of 3.2 gigawatts.
Therefore, this dam will bring a steady stream of green energy to the coastal countries. However, many experts think this idea is ridiculous.
abstract
People always ask me why I take blogging so seriously.
I have several reasons.
(1) Writing can organize thoughts.
I’m not good at thinking on the spot, preferring to think after the fact. Writing forces me to organize my thoughts in a coherent way and to discover which ones don’t make sense.
Writing is like a filter that removes the nonsense from your mind.
If you had asked me before what the purpose of writing was, I would have answered that writing turns ideas into words. But, I would answer now, writing itself can develop and change your ideas. Writing is not only a record, but also a clearer way of thinking and generating ideas.
Even if writing doesn’t give me new ideas, it still allows me to express myself in better terms.
(2) Writing can share knowledge and ideas.
Blogs provide more details than microblogs and take much less time to read than books. Blog posts are easy to read at your own pace, unlike videos which have to be watched at the pace of the person who filmed them, and blog posts are easy to link to and reference.
It inspires and comforts me that the articles I write may be useful to others.
(3) Writing helps me learn new things.
I sometimes use blogging as a way to learn new things, by writing about a topic I don’t know much about and learning some details in depth.
Even when I write about something I know well, I learn new details in the process.
(4) Blogging allows me to practice writing.
Blogging is a writing exercise and the freedom to write about whatever I really want. This means I can write more.
Blogging also means I get feedback from a global audience, which motivates me to work harder at writing it well.
(5) Blogging allows me to find mistakes. Posting the blog online is a great way to quickly learn about my mistakes. Readers often leave comments pointing out errors in articles.
(6) Blogs can provide links. If I often have other people asking me about something, I’ll write a blog and give them the link to it, so it’s easy.
(7) Blogs satisfy my vanity. I feel good when my articles get a lot of clicks or are mentioned elsewhere. Moreover, this will bring huge traffic in a short period of time.
(8) Blogs can provide unexpected opportunities. Someone read my article and invited me to write a paid piece of material for their website.
(9) Make money. I make some money by placing ads or promoting products on my blog.
speech
1,
Don’t write code when you’re tired. Dedication and professionalism are reflected more in your discipline than in the time invested.
— Robert C. Martin (Uncle Bob), author of Clean Coder

In November 2022, OpenAI released ChatGPT, which suddenly triggered a technological explosion that people had never seen before. The Turing test became history, search engines became an endangered species, any university papers were no longer credible, and there were no jobs. It is safe and no scientific issue is set in stone.
3.
A huge mistake web designers make is assuming that users will read the page carefully. But in reality, users don’t read, they just scan the page.
Because most users just want to get something done, and do it quickly, without knowing anything unnecessary.
— “The 10 Most Costly Design Mistakes”
4.
Long-term plans are speculative and no one can predict them. Lengthy plans will eventually become fossils in filing cabinets.
Just decide what you want to do this week, figure out the next most important task, and do it without worrying about your plans for the year.
Working without a plan may seem like a no-brainer, but blindly following an unrealistic plan can have even worse consequences.
