It is much more practical to master basic theories and classical design methods than to pursue some so-called new technologies.

It is more practical to master basic theories and classical design methods than to pursue some so-called new technologies.From the perspective of others' blogs, although I have always had this idea, I have never summed up a sentence. I think there are not many technologies that can be called "innovations" Currently. They mainly deal with complicated and changing needs. In such an environment, it is more important to master basic knowledge. From the operating system, you can learn the multi-process and multi-thread design and use it in the design and development of your own high-performance concurrent projects. From the principle of computer network, the design concept of multi-layer and message transmission, such as routing, gateway, and OSI, can be used in enterprise integrated applications of message integration, as well as the principles and design of TCP/IP, it is worth learning. Unlike scientists, a project must be done by others. Instead, they must apply the good and stable practices that others have done to their own projects. In this it world, 99% of things have been done. You should first learn what others have done, understand why others have done so, what is the basic theory, and after digestion, it is better to use and then to innovate on this basis.
