Some reflections on programming

About programmer technology experts

Those who are popular are generally not experts. Because if you want to be popular, you need time to market it. Marketing capabilities and technical capabilities are orthogonal. If a person spends a lot of time on marketing, it will be difficult to spend time on technical improvement. Don't think that he is a master just because he talks about a field that you don't understand. A person living in the desert will be very excited when he hears the description of anyone who has seen the sea. But if someone tells him that a camel has six Just a foot, he would definitely sneer at it. Daniel will speak in great detail about areas he is familiar with, and will also ask the right questions about areas he is unfamiliar with.

About learning new knowledge about programming

Learning a new skill best requires in-depth understanding. But in today's era when various frameworks and various class libraries require contact. It is difficult to truly understand all libraries. Suppose you are learning python. If you really understand the print statement, you need to know python's syntax parser, C language calls, and then the IO system. This is not possible for most people, most people rely on memory. On the other hand, if you need to make socket requests when learning Python, and you are familiar with Java's socket implementation, you will quickly learn how to use Python's sockets. To sum up, there are two ways to quickly learn new knowledge. One is to have a strong memory, and the other is to have a deep understanding of basic knowledge.

About attention

If you are doing mechanical things, just rely on human inertia. If you are doing creative work, you need a lot of concentration. Attention is a consumable product. If you dwell on a problem for too long, your attention will be reduced, resulting in low efficiency and making mistakes more likely. You can rest at this time. Let your mind cool down. Improving concentration allows you to do more in a short amount of time, giving you time to live and not just work.

About feedback

In technical exchanges, if others don’t oppose you, it doesn’t mean they agree with you. Maybe they are too lazy to share their knowledge with you. If you are wrong, others may not necessarily tell you, but they may be embarrassed to attack you. Therefore, it is important to obtain other people's true thoughts.

About reflection

You should always ask yourself what the meaning of doing the current thing is. What's the point of doing this now? There are two advantages to doing this. First, you are more willing to do it after you understand the meaning. The second is if the error can be discovered in time and then corrected.

About the overall view

To solve a problem, you should first figure out what resources you have, what solutions you have, and estimate the time for various solutions. Instead of immediately implementing the first method that comes to mind. Just like the relationship between breadth search and depth search. If you only use one method, the efficiency may be very slow. If your initial intuition is wrong, it will take you further and further away from the solution.
