Back-end growth journey
Today is the first day of the back-end growth journey and the first day of the course. In the days to come, I will record the knowledge and insights I have learned every day.
Knowledge point
On the first day of the course, we talked about some of the content we will learn later, which is the content of sub-system learning. The focus of today is the need to master the first principles of software development technology. Hearing first-principles, I believe that everyone knows that there is a first-principle in physics. That ’s right, this first-principle is essentially the same as the first-principle in physics, only the things that work are different. The first principle is to let us grasp the most essential things of things, and calculate the development of things according to the laws of things themselves, not just looking at the surface and ignoring the most essential things of things, and getting lost.
Perception
Today's computer field is an ever-changing field, and the trend is changing very rapidly. At this time, such a situation may occur. Then, just after learning this technology, I didn't expect that new technologies will appear again, and after learning new technologies, they will appear again. Newer technology, so as to keep up with the trend at all times, it is difficult to truly learn useful technology, and let ’s not mention this process is very painful, let ’s take technology as an example, and learn a new technology quickly It ’s outdated, and will face new technologies, so that it seems to have learned a lot of things, but in fact it is not proficient in everything, so when learning, we need to use the first principles to build our thinking Frame system, through this principle to understand the most basic and most critical technical principle of each technology, know how this technology develops, how to operate, how to realize, build these contents into a thinking frame system. My high school teacher once said that if you can build the content of a book into a framework of thinking, then you will learn 80% of the things, and the other 20% will need your own in-depth understanding. Therefore, I think that when learning a technology, you can try to build your own thinking framework and build it on your own understanding. That's all for today's lecture, thank you!
