famous search engine Google. We know that this search engine not only has accurate search results, but also has an extremely fast search speed. The search result is accurate, which is the performance of the program algorithm. The fast search speed is related to the robust behavior of components and programs of the entire system. If you want to write your own program, you can also "easily" in the case of high traffic, it is necessary to conduct a negative pressure test on the program.

generate a signal, the signal is blocked and in the pending state. When the SIGQUIT signal is received, the blocking function is lifted and enters the delivery status, but only one response is made to the signal. Even if you press ctrl + c many times, the reason is that, the SIGINT is an unreliable signal and does not support queuing. Only one SIGINT is retained.
If we use real-time signals, such as SIGRTMIN, the signal can be queued and will not be lost. After blocking is removed, each sig

The next paragraph is to determine if there is an AJAX request
But it's really hard to understand
Can you comment
Determine if there is an AJAX request $act =!empty ($_get[' act ')? $_get[' act ': '; if ($act = = ' Cat_rec ') { $rec _array = Array (1 = ' best ', 2 = ' new ', 3 = ' hot '); $rec _type =!empty ($_
As we continue to study the Ajax framework, we are more exposed to call and apply.So we will discuss call and apply again,1) undoubtedly, the simplest explanation of call is to display the hidden first parameter. Generally, when a function is called, an additional hidden parameter is the object to which the function belongs (if it is not specific to it, it is global (such as window) object), you can use this keyword to access the function.Call (thisarg [, arg1, arg2…] ]).The call (apply) method
