The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu
However, Jiang Min, vice president of the Real Education Fund, said that due to the high investment cost of offline institutions and geographical restrictions on their development, it is more optimistic about online education. At present, besides children's English, the demand for thinking ability training is very large and the market facing it is also wider. "Children's English has explored a relatively mature online development model, and their thinking ability can be used for reference. Moreover, users' acceptance of online education products is increasing day by day. It is relatively easy to start the market for education, and there are more talents who know the operation and management of online education. In addition, the cultivation of children's thinking ability pays more attention to the thinking process, and the requirements for expression and communication are relatively weak, and the demand for one-on-one teaching is relatively low. The cultivation of online thinking ability is likely to accelerate faster than the development of online children's English. "

Information Theory: I forget which publishing house it was. It is a very thin book and it is very good. There is a good talk about the measurement of information, the understanding of entropy and the Markov process (there is no such thing in the company now, I'll go back and find it and make it up). Mastering this knowledge, it is good for you to understand the cross entropy and relative entropy, which look similar but easy to confuse. At least you know why many machine learning algorithms like to use cross entropy as cost function ~

"Admitting people's inability to do anything at the end of their lives can only look for greater possibilities under this premise. For example, take your time to arrange your funeral and fulfill some wishes. Even if you have a good communication with your relatives and express your regrets, it is more likely to realize your wishes when you die." This is Huang Weiping's advice to the dying.

This may not be easy to understand. Let's change the angle that is easy to understand and start from the beginning.
Liz Bonnin presents a controversial and provocative episode of Horizon, investigating how new scientific research is raising hard questions about zoos - the film explores how and why zoos keep animals, and whether they need to change to keep up with modern science or ultimately be consigned to history.Should zoos cull their animals to manage populations? Liz travels to Copenhagen Zoo, who killed a giraffe and fed it to the lions, to witness their culling process first hand. They think it is a natural part of zoo keeping that is often swept under the carpet. Should some animals never be kept in captivity? In a world exclusive, Liz visits SeaWorld in Florida and asks if captivity drove one of their orcas to kill his trainer.But could zoos be the answer to conserving endangered species? Liz examines their record, from helping breed pandas for the wild to efforts to save the rhinos. She meets one of the last surviving northern white rhinos and discovers the future of this species now lies in a multimillion-dollar programme to engineer them from stem cells. Veteran conservation scientist Dr Sarah Bexell tells Liz the science of captive breeding is giving humanity false hope.
