Differences between simple factories and factory methods: Simple factories and factory method patterns look very similar, especially specific factories in simple factories and factory methods. Simple factory, all things have been done in one place. However, the factory method creates a framework for subclasses to decide how to implement it. For example, in the factory method, the OrderPizza method creates a general framework to create pizza. The OrderPizza method relies on the factory method to create specific classes and make actual pizza. It is possible to decide what the actual products manufactured are by inheriting the factory. Simple factories do not have this flexibility.1999年，洛杉矶，政府执法技术中心开发出用于训练警探的模拟机原型。这种虚拟现实模拟机装载有最先进人工智能技术，使用者需追捕电脑生成罪犯席德67（结合人类所有邪恶），以锻炼他们的侦探技巧。但是，这个复杂的“猫捉老鼠”系统有一个致命的后果：狡猾的席德67摆脱束缚离开了虚拟空间，进入现实世界作恶。前警察帕克巴恩斯被认为是最有机会制服席德67的人。在犯罪行为专家卡特的帮助下，巴恩斯必须穿梭于现实和虚拟世界，在新千年之前抓住席德。同时，巴恩斯在席德67身上发现了杀害他的妻子和女儿的变态杀手的影子。这场猎人的游戏变得复杂起来，赌注也更加高昂。 在完全计算机化的时代，一名邪恶的科学家研制出一个强大的杀人程序：里面融合了超过150个连环杀手的变态心理和杀人手法。而这个程序的职能使他挣脱了科学家的控制独立行凶。他拥有人的外形，并能任意修复身体的损伤，他的名字叫Sid 67。洛杉矶警方研制出一个追踪Sid 67的仪器，他们决定用一名囚犯做实验，追踪Sid 67。偶尔花生和玉米有疑难之处向他请教，他便耐心地给他们讲解，低沉而温和的声音回荡在书房，让两人觉得十分温馨。Since the 1920s, the influx of Western journalists into China has been like crucian carp crossing the river, but as far as the social status at that time is concerned, no one can expect Aban to match it. Aban is naturally competitive and can't compete for emergencies in the front line, but his real advantage lies in his extensive upper-level relations. The top level of the Chinese government and the top level of Japan, the United States, Britain, the Soviet Union and other countries in China are full of his personal friends. At the beginning, the national government wanted to expel him from the country, but later, all four families took him as their guest of honor. Japan attaches more importance to the fact that the top leaders of various factions and departments in civil and military affairs are eager to break through his threshold. The Soviet Union was also interesting. While setting off a wave of criticism of Aban, it sent an ambassador to talk with him in secret and entrusted him with conveying high-level meanings. As for the United States and Britain, it goes without saying. The importance of Aban lies in the fact that his role has completely gone beyond that of a mere reporter. To the U.S. Government, he is an unpaid senior intelligence agent, providing top secret information free of charge, weighing more than any official spy. To the rest of the governments, he is a supernumerary U.S. Diplomat, and his role is often beyond the reach of U.S. Ambassadors. Therefore, between Japan and the United States, between China and the United States, and between the United States and the United States, he has to send messages frequently. As for the infighting among various countries, they should also reveal their secrets to him so that they can be published in the New York Times and confuse each other. For example, before Japan officially joined the Axis, because of the confrontation between the two factions at the highest level, some people secretly told each other the news, which made him get a global super scoop for no reason. All this, of course, depends on the golden signboard of the New York Times and its inexhaustible resources.Generally speaking, a DDOS attacker is a program that implements DDOS denial attacks. With his help, he can launch attacks on other computers with a high success rate. By using this kind of attacker, even less powerful hackers can be used freely and easily restrict other people's computers from accessing certain legal websites anytime and anywhere.
