Because they forget: happiness comes from creation. Of cours

dynamics of components. This is because the high-frequency dynamics involve the internal structure of each component, while the low-frequency dynamics involve the interaction of each component. 4) hierarchical systems are generally composed of only a few different subsystems in different ways of arrangement and combination. 5) We found that the complex systems that are running are always evolved from the simple systems that were previously running ...... Any complicated system that is randomly

This article is a short story about PHP serialization/object Injection Vulnerability Analysis, which describes how to get a remote shell for a host. If you want to test this vulnerability yourself, you can do so through XVWA and Kevgir. The first step in exploiting the exploits, we begin to test whether the target application has PHP serialization. In order to assist the test, we used the Burpsuite superse

return New F ();}He is an encapsulation of class inheritance, in fact, the transition object is equivalent to the subclass in the class inheritance, but in the prototype as a transitional object appears, in order to create to return the new instantiated object.Of course, if you feel the need to cache the F transition, you don't have to create a new transition class F each time, and then the Object.create (

background, and it successfully dissolves the "software crisis" by emphasizing the expansibility and repeatability of design and implementation. Since then, the object-oriented design of the program began in the industry, and gradually become the mainstream. The evolution from C to C + + happens at this time, naturall
