The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.AbstractCalculator is an auxiliary class that provides auxiliary methods. Next, implement each of the following classes in turn:We know from the above analysis that the magnification of the explosive arrow is 70% of that of the flame arrow under the condition of no critical strike and no head explosion. Then why is the damage of the flame arrow lower than that of the explosion arrow? According to analysis from the upstairs, the number of explosive arrows is 3W3 (about), which will be improved with the war roar. The increase is not much, about 13%, then about 3W7. AOE 20w * 0.7 of Flame Arrow is 14w. When the explosion occurs, five enemies, each of whom will be affected by the explosion AOE of the other four enemies, that is 3W7*4=14. 8W. In total, each enemy received 14+14.8 = 28.8 w of damage. The inference is consistent with the actual result.The audience at the back said it. . .　　当他苏醒过来，才发现自己已被一群猿人团团包围，并被带往丛林更深处的猿人部落，与其它人类关在一起，里欧才惊觉这是个由猿人统治的星球，而人类已沦为次等种，打破人类一向自以为是宇宙中心的想法……该剧主要讲述大学新生杰克·莫顿加入了一个神秘的社团，随后接触到一系列在现代社会不该不存在的东西——魔法、怪物，当他了解的越来越多，竟揭开了自己家族的黑暗秘密，并卷入狼人和黑魔法绵延久远的战争...影片改编自发生在澳大利亚1990年代的真实事件。当时在澳大利亚阿德莱德有一个连环杀人犯，他因为自己的心理需要而杀人，在接连犯下了十几条命案之后，这个叫做约翰·本廷的人终于被警方逮捕。因为有8个受害者的尸体被他装在了雪镇的木桶里，所以这个连环凶手又被叫做雪镇杀人狂（Snowtown murders）或者是木桶杀人狂（Bodies in Barrels murders）。在这两个名字中，murder都用了复数，其含义是约翰·本廷有三个帮手，分别是罗伯特·瓦格纳、马克·海顿和詹姆斯·瓦拉萨基斯。而影片中的杰米就是以瓦拉萨基斯为原型创造的。他认识本廷，并成为其团伙中一员的时候，正好是16岁。
