1. Explanation of several angles Euler angle:http://baike.baidu.com/link?url= Vajuhz-luawv7zua-67dibb0jjwyyqqnwnqeejdrcomwdt1xrtjgq2anyojngfrkfoo3t_1gcwpebbgp3npfzq With Euler's angle, you can determine the following, roll angle, pitch angle, and yaw angle . In general, the right, front and top three directions of the carrier are formed right-hand system, the axis around the forward rotation is the roll angle , rotation around the right axis is the pitch angle , the axis around the upward

CSRF solution, the current contact is a token value for each form submission, which is then validated when the form is submitted. 2. Clearly know the difference between the various comparison operators PHP's comparison operator, which can be said to be a very small point of attention, but at some point it is really important. For example, many times we have to think about whether to use = = or = =, if you have used Strpos () This function, the following code may give you an intuitive feeling:

feeling, after using the ternary operator, we can remove a bunch of if else statements, the code is short and cool. $host = strlen ($host) > 0? $host: Htmlentities ($host); 7. Using caching The current PHP popular caching technology may be redis and memcached, in the official PHP document, there are memcached tutorial, as for Redis, I recently in the study, follow-up will give some tutorials, if all goes well. 8.

. Disk space can be provided by one or more logical volumes that are equivalent to the partitions residing on the physical disk. Both volume groups and logical volumes are assigned a name when they are created. For a volume group, there is a directory with the same name as the volume group in the/dev directory, under which a symbolic link with the same name as the logical volume has been created. For example, the device file for the MYLV logical volume in the MYVG volume group is/DEV/MYVG/MYLV.L

Proxyhandler processor (proxy settings)Using proxy IP, this is the second trick of the crawler/anti-crawler, and is usually the best.Many websites will detect the number of times an IP is visited (through traffic statistics, system logs, etc.), and if the number of visits is not as normal, it will prohibit access to this IP.So we can set up some proxy server, change an agent every time, even if the IP is forbidden, can still change the IP to continue crawling.#_ *_ coding:utf-8 _*_ "Created on J

with the above code, but you don't need to manage source permissions. 5, Tar Bomb The tar command is used to put multiple files into a file in a. tar format (archive file). Tape Archive (Tar) bomb can be created by him. When it comes to compression, this archive file generates tens of thousands of similar name files that appear in the current directory instead of the new directory. When you receive a tar file, create a new protected directory on a regular basis, and then put the accepted ta
