Today, distributed attacks are really feasible because criminals have thousands of hosts for him to carry out denial of service (DoS) attacks. Since these large numbers of hosts can continuously increase or decrease and can change their IP addresses and their connections, it is still a challenge to prevent such attacks.王尚书颔首道：本官即刻进宫。SYN flooding attacks can attack with fewer packets than ordinary brute-force DoS attacks that only send a large number of packets to the target network. However, this requires some understanding of the server's operating system, such as how much backlog queue space it allocates and how long it will keep the TCB in the SYN-RECIEVED state before timeout and discarding the TCB. For example, an attacker can send a certain number of SYN packets that are exactly the size of the backlog queue, and their cycles are just the time when the TCB is recycled, thus making the server permanently unavailable.麻衣总是将各种物品缩减控制在最低需要程度。麻衣贯彻着“扔”之道，而她的妈妈和外婆却觉得，扔了可惜。东日本大地震后，经历了与家人分离的她重新开始审视与这些物品的生活...1. As a math student, I have studied math for four years, and I don't agree with the bibliography you gave at random. First, there is no step type and it is unfriendly to beginners. Your title and the purpose of writing this series are probably for Xiaobai to see. So, may I ask, a Xiaobai needs to see the principle of mathematical analysis? ? Is it necessary to look at Princeton Calculus Principle to learn artificial intelligence? ? In my shallow understanding, the biggest difference between mathematical analysis and advanced mathematics is the same theorem. High numbers only require that they can be used. Mathematical analysis is rigorous and will definitely give proof. However, for the mathematics needed in most artificial intelligence, you need to prove the correctness and completeness of this theorem in your work? ? I'm afraid the project will be closed long ago when you prove it. You replied to me that this is only a bibliography, not a recommended bibliography, but most of the following comments decided to give up when they saw the book list. If you put these books out, it will be instructive to those who read your articles. I think you are misleading people. Second, I have roughly deduced from the number of references you have made that you may not have a framework for the mathematics of the whole artificial intelligence, otherwise there would not have been such irresponsible recommendations. However, out of respect for you, I did not question your ability. I only gave a brief recommendation in the comments on the suitable math bibliography for beginners.2017年5月15日爱奇艺独播。 美国留学进修音乐的江上饮，由于在金三角惹到地方黑帮，只好到一家泰国唐人街技校当教导主任打工作为赔偿。这所技校只有四个专业，一个是一群泰拳高手组成的泰式按摩专业，一个以杀马特为美学最高标准的美容美发专业，一个是男女不分的模特礼仪专业，还有就是放弃了所有美食套路专精各种咖喱的烹饪专业。虽然四大专业看起来有些四六不靠，但是为了生存，江上饮只好放手一搏来到学校，结果面试中江上饮和校长产生了一个不大不小的误会，使得江上饮从一个“海归音乐教师”变成了“遣返黑帮教父”。于是如何在一群叛逆少年和怪咖教师中生存下去就成了江上饮最大的考验。而且最让江上饮头疼的除了日常工作之外，他还有一个既不靠谱又无靠山的“废柴盟友”史飞楼，史飞楼因暗恋着校长的女儿---sun老师。史飞楼本职工作是一名洗车工，是一个内心善良，但是行事猥琐的怪异少年。于是这样两个不着调的二人组出现在了这个充满泰式风情的次元技校当中，必然会引发了一系列令人啼笑皆非的故事。杨长帆笑道，哥哥你这就不讲究了，不告诉我这个规矩自己就出死价，早知道我也开死价了。
