I searched for an article about VI on the Internet.

As I expected, the quality of Chinese VI materials on the Internet is average.

In my experience, if you are really interested in a certain technology, you should try to read the English documents as much as possible and join a foreign community where the English language is used for communication.

The main reason is that my country does not respect intellectual property rights very much. Many websites in the same article are transferred. If I search online, the results are the same, which is a waste of time. This is not a manifestation of the small and low cost for Chinese users?

For example, if you Google "VI advanced command Collection", how many times have you copied this article?

I also want to talk about the other reason for the low quality of Chinese materials. In this regard, I have some intuition and personal experience, as well as some people I trust to verify. But I cannot be sure.

This is because China's history has not passed the true scientific enlightenment. Many people have been trained by engineers, but have not mastered their thinking methods. Wang Xiaobo said, "one of my teachers said that Chinese people's understanding of science has gone through several stages. First, science is like a flood of beasts. Therefore, electric poles are cut down and railways are destroyed (The Role of Yihetuan). Then, science is like magic, and several methods can be learned to build a strong ship; later, as the holy religion of the scientific power, worship it. After he became an accomplished historian, he realized that science is a process of continuous learning ." This statement also applies to engineering technology.

The reason why some Chinese technical articles are of low quality is that these articles list the so-called technical tips, but do not describe the internal logical relationship between these tips. The reason is that the author of the article treats technology as a secret. Technical tips have become an isolated spell.

For example, it is inefficient to delete D $ from the current position to the end of a row. If you know that $ represents the end of a row and this representation is common in regular expressions, you can understand why d $ represents deletion to the end of a row. In addition, you can draw a line by mistake. d ^ should indicate to be deleted to the beginning of the line, and D/should indicate to be deleted to a specific character found by/(actually a regular expression ). /Is positive search ,? It should be reverse lookup. Why? The logic contained in VI is that if the function of a character is A, holding down the character and shift key (that is, capital characters) is the opposite of the function, or a function expansion (if there is no direction ).

The essence of technology is to use logic to draw inferences, not to memorize, not to memorize a certain spell and then to a specific real scenario.
