Everyone has seen this effect.
How can I introduce him to my website? Let's analyze it together.
You can easily obtain the keyword by using the "development tool" of ie9. when you enter a keyword, how to obtain the smart prompt is related to the keyword.
Let's take a look.
We can clearly see that every time we modify the query box, Baidu sends an Ajax request to call the corresponding data.
The address is:
types of FIR (from Baidu Library ):
When w = 0 and PI are used for different types of filters, it must be noted that their values are 0, which affects filter selection.
Note that the FIR pole is at the origin, and the zero point is paired, And the pole number is equal to zero points.
In practice, the window function truncation method is used to design the FIR filter.
Rectangular Window disadvantages:
Sudden truncation causes the Gini effect, because the rectangular window has a relatively la
Adding monitoring of files or directories, you can specify that you need to monitor those file change events
Inotify_rm_watch
Remove a monitoring file or directory from the monitoring list
Read
Read event information
Close
Closes the file descriptor and removes all monitoring on the descriptor
Event notificationIn INotify, the file event is represented by the struct inotify_event, and its structure is as follows:struct
