This leads to an obvious potential DoS attack. Incoming SYN packets will be allocated too many TCB and the host's kernel memory will be exhausted. In order to avoid this memory depletion, the operating system usually associates a "backlog" queue parameter with the listening interface, which maintains both the upper TCB number of connections and the SYN-RECEIVED state. Although this scheme protects the host's available memory from attack, the backlog queue itself brings a (small) source of attack. When there is no space in the backlog, it is impossible to respond to new connection requests unless the TCB can be recycled or removed from the SYN-RECIEVE state.1944年，在苍茫的大海上，一艘装满中国战俘和劳工的货运船开往日本。在这些中国的战俘和劳工中，有以周尚文为首的国民党军队战俘；以萧汉生为首的八路军战俘；以及以刘家正为中心的普通劳工。这些战俘和劳工不明不白地被带到了一个叫做仓津岛的日本小岛上。在仓津岛上，日军为了防备可能会在日本本土发生的决战，极为保密地进行着军事防御工事的建设。为了建设这个军事防御工事，许多中国的战俘和劳工每天被迫承受着沉重的体力劳动，他们忍饥挨饿，饱尝日本兵屈辱的折磨。如若想逃跑，唯一的出路就是被残酷的杀掉。在这样残酷而惨无人道的环境中，战俘和劳工们仍期盼着回家的日子……The template method pattern defines the algorithm skeleton in an operation in an abstract class and delays the implementation of some specific steps to subclasses. The template method enables subclasses to redefine specific steps of the algorithm without changing the structure of the algorithm, thus achieving the effect of reusing codes. The specific structure diagram is shown below.逃走的毕龙接到了策划这次杀人案的电话，并且得知只有按照他所说帮他找到些东西才能摆脱杀人的罪名，毕龙只好按着他所说的做。讲述的是一个认为人生的价值就是钱的富二代与一个生活窘迫到极点的女人戏剧般相遇，追寻真爱意义的故事。Round 3: 1-2,《蛋黄人》讲述了屌丝大学生李致远霉运当头——被心中的女神当成闺蜜，患了癌症只剩三个月可活。此时一个像蛋黄的外星生物入侵了他的身体，不但治好癌症，还给了他超人的体质。但危险也随之而来，为了朋友和爱人，屌丝必须要逆袭变英雄.....
