# s-U "Q + d; K7 j1 r, PWhenever the network fails, many people subconsciously think it is the cause of switches, routers and other equipment, but the reality is often caused by some humble accessories, such as network cables. No matter whether the project starts to be implemented or the later troubleshooting, belittling the network cable will often cause us to pay an unexpected price.PS: Many forums have seen beginners ask whether WCF still needs to learn in depth, because they think these technologies may be outdated. Maybe Microsoft will launch a new SOA implementation scheme at that time. Wouldn't it be a waste of time to learn in depth, so they feel that there is no need to learn in depth and just know how to use them. I had the same feeling about this problem before, but now I think that although WCF technology may be replaced, the key to understanding a technology in depth is not to know some more advanced API calls, but to understand its implementation mechanism and way of thinking. Even if the latter technology is replaced, the mechanism behind it is definitely similar. Therefore, if you have a thorough understanding of a technology, you will feel familiar with the new technology and relaxed about it. In addition, after you have a thorough understanding of a technology, you dare to say that you have mastered the technology well during the interview, instead of saying that you use it a lot at ordinary times. Once you ask deeply, you do not know the implementation principle behind it. This is also why I want to write WCF series. I hope this opinion is helpful to some beginners.围绕着“穷屌丝”与“白富美”的爱情而展开，讲诉了陈健豪，一个出身自家境并不宽裕的男孩。家境贫寒的他几乎没有什么幸运会降落在他的身上，要说到他人生中最幸运的事情应该就是他有小了这个朋友吧。小了是出身于富裕家庭的男孩，每当阿豪拮据之时，他便塞钱给阿豪，帮助其度过难关。何恋慈，她是阿豪暗恋了十二年的女神。从幼儿园开始，她便是学校里公认的校花。出于自卑，阿豪始终认为自己没有资格靠近何恋慈，甚至是不敢跟她讲话。在机缘巧合之下，陈健豪意外发现何恋慈喜欢看别人跳舞，于是，他便开始学习跳舞，并希望有天可以在何恋慈面前跳舞。于是，一段带着青春的纯纯气息的爱情在舞蹈中慢慢酝酿着……　　故事发生在从近未来到两百年后的历史跨度上，地球文明被三体用一种叫做智子的超级科技锁死，基础研究因而停滞不前。但人类仍然需要在此基础上不断前进来抵御即将到来的三体人的进攻，守卫自己的家园和人类文明。在更广大的基础上，三体文明和人类文明都是黑暗森林下的猎手，小心翼翼的保护好自己并且清理别人，为文明的存续而挣扎。该网剧讲述了时光（胡先煦 饰）在机缘巧合之下发现一个古老的棋盘，从而认识了盘踞在棋盘内、历经千年的南梁围棋第一人——褚嬴，并在他的熏陶下逐渐对围棋产生兴趣，并励志成为职业围棋手的故事。This is the first sub!
