于是，两人带着红椒、紫茄和香荽下楼去后院了。Public void del (Observer observer) {B) Design principles. 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).Call for Strange IronAnother main technology to prevent SYN attacks is to adjust TCP/IP protocol stack and modify TCP protocol implementation. The main methods include SynAttackProtect protection mechanism, SYN cookies technology, increasing the maximum half connection and shortening the timeout time. The adjustment of TCP/IP protocol stack may cause some functions to be limited, and administrators should do this work on the premise of full understanding and testing.Later, the battle was the same, and it was fought several times over and over again. The ammunition consumed most of the time. The front of the position was covered with enemy bodies. I remember that after resisting the fifth attack, the Vietnamese army stopped there. It did not launch any new attack for a long time. Until more than 3 pm, the Vietnamese army actually "let dogs bite"! I was so impressed by the way the dog looked, The appearance is about the same as that of the domestic dog in my hometown. But there was no hair all over her body. The two eyes are still very far apart, The key is to run very fast. There was some grass in front of the position, and craters were everywhere bombed by the subsequent shelling. The 152-meter shell was a large crater with a diameter of 5 or 6 meters. However, this kind of "dog" can easily cross one with one jump, and there is no need to slow down in continuous jumping. The speed of impact is definitely not comparable to that of human beings. "林聪朝山坡上望去，只见黑娃飞奔下来，忙道：黑娃来了。
