First of all, the simple factory mode does not belong to the 23 design modes. Simple factories are generally divided into ordinary simple factories, multi-method simple factories and static method simple factories.
In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).

This factory has been in operation for eight years since 2004. According to incomplete statistics, there are more than 10 new cancer cases a year in Shaner Village, which has a population of only 3,000 each year. This number is still increasing every year, and there is a trend of getting younger and younger! No one knows who will turn to the "next batch" and who will turn to himself. Family? Relatives and friends? No one dares to think about it.
迈克尔·B·乔丹主演的法律题材新片《正义的慈悲》(Just Mercy)北美定档2020年1月17日上映，华纳还定档了一部招魂宇宙新片2019年7月3日上映，目前未定名，也无其他信息。 《正义的慈悲》将由德斯汀·克里顿(《少年收容所》《玻璃城堡》)执导，Andrew Lanham(《玻璃城堡》《陋室》)操刀剧本。改编自美国律师布莱恩·史蒂文森所著畅销书《正义的慈悲：美国司法中的苦难与救赎》，讲述他如何在有缺陷的法律体系中为司法公正而奋斗，为推动美国刑事司法制度的改善做出巨大贡献。 影片聚焦史蒂文森办的第一个案子：黑人青年Walter McMillian因一项他并没有犯的罪行而被判死刑，尽管他有充分的不在场证明。在最终被无罪释放之前，他在死囚牢房呆了六年。

In the last article, we explained Redis' master-slave cluster mode in detail. In fact, the configuration of this cluster mode is very simple. It only needs to be configured on Slave's nodes. The configuration of Master's master node does not need to be changed. However, one thing is that the persistent configuration of Master and Slave nodes should be consistent as far as possible, otherwise there will be strange problems. Starting today, we will begin to talk about the second mode of Redis cluster mode. That is, the "Sentinel" mode, which was provided from version 2.6 of Redis, but the mode of this version was unstable at that time. The Sentinel mode did not stabilize until version 2.8 of Redis. In the production environment, if you want to use the Sentinel mode of Redis, you will try to use the version after version 2.8 of Redis. Whether it is master-slave mode or sentinel mode, both modes have a problem and cannot be expanded horizontally, and the high availability of these two modes will be limited by the memory of Master master node. Another point is that the configuration of Sentinel mode is not simple or even complicated, so neither mode is recommended in industrial scenes. If you want to use it, you must have solutions to related problems to avoid subsequent problems.
