AI is in the current air outlet, so many people want to fish in troubled waters and get a piece of the action. However, many people may not even know what AI is. The connection and difference between AI, in-depth learning, machine learning, data mining and data analysis are also unclear. As a result, many training courses have sprung up, which cost a lot of money to teach demo and adjust the participants. They have taught you to study engineers quickly and deeply in one month, making a lot of money. We should abandon this kind of industry atmosphere! In my opinion, any AI training currently on the market is not worth attending! Don't give money to others, won't it hurt? -However, when everyone taught themselves, they did not know where to start.

号称“史上最佳剧集”之一的《宋飞正传》，其知名度与受欢迎度毫不逊色于大部分国人熟知的经典喜剧《老友记》（《六人行》）。故事也是以纽约为背景，讲述四个曼哈顿年轻人的故事。故事围绕喜剧演员宋飞展开，主要人物有：自己演自己的杰瑞·宋飞、宋飞的多年老友乔治、宋飞的前女友伊莲，还有宋飞神叨叨的对门邻居克莱默。《宋飞正传》每集故事之间没有关联性，没有贯穿全剧的主题或者主线，主要情节就是讲述四个主人公的日常生活，巧妙地将笑料暗藏其中。编剧从小人物的视角出发，描绘出色的对白语言、演员精湛纯熟的演技以及美式无厘头的插科打诨，是该剧大获成功的原因。《宋飞正传》在播出之后立即得到了评论界和观众的一致好评与喜爱，收视率连年居高，演职员获得数十个重要奖项或提名，Seinfeld和David也从中获得数亿美元的收入。2002年美国权威电视杂志《手指指南》（TV GUIDE）组织的“史上50部最佳剧集”（50 Greatest Shows of All Time）评选中本剧当仁不让名列第一。

After receiving the RST packet, the receiving end does not need to send an ACK packet to confirm it.
