Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).At present, there is no firewall that can protect DNS server attacks, only a few professional protection equipment can do it.Some plants are very picky when choosing pollinators. The flowers of European Trollius are like a real safe deposit box, and only six kinds of insects know the code to open the safe deposit box. These lucky people all come from the genus Brevicorn. Only they know how to get into the sepals of European Trollius and find the center of the flower. However, no matter how hard other insects try, they can only fail with disappointment. The short-horned flower fly, which has gone to great pains to pollinate European Trollius, will naturally receive considerable "remuneration". Female short-horned flower flies lay eggs on the carpels of flowers. When the larvae are hatched, they will eat the seeds of flowers and grow up. This symbiotic relationship also has certain risks for European Trollius. The more short-horned flower flies, the greater the chance of pollination, but at the same time, the more insects parasitic on flowers. The cooperative relationship between the two was formed millions of years ago and continues to this day. It is a model of relative balance and harmonious symbiosis in nature.
