Network search is based on the user to provide the best service to customers one of the important ways, in order to achieve better results, we need to understand user behavior, through the Search engine results page to find users interested in the page, after several experiments have proved that there are three major types of keywords, these keywords may have different click through rate.

Wednesday of 06:06am performing tasks.3. Dailytimeintervaltrigger will be within a given time interval every N (1, 2, 3 ...) Seconds or hours to perform the task. For example: set to run from Monday to Friday 10:10 ~ 18:00 every 60 minutes. Although Simpletrigger can achieve similar tasks, Dailytimeintervaltrigger is not subject to the misfired tasks mentioned above.4.CalendarIntervalTrigger is typically used to process recurring interval tasks based on calendar time. You can handle tasks that

In Swift we have a powerful high-level logic abstraction, while low-level operations are deliberately limited. But in some cases we still want to do some hack work in C, and the cat will take a look at how to do it.Hacking is happy!!! ;]As the title says, now I have an int variable x, I want to get its address, then convert it to char type address, and then change the address of the content +1, if the C language to represent is:121,*pi = xchar *pc = (char *)pi1There are 2 questions to be written

Here, we refer to magic numbers for different file types. It specifies the first few bytes of a file that are used to uniquely distinguish other file types. With these magic numbers, we can easily differentiate different files, which makes programming easier, because I reduce the time it takes for us to differentiate t

This process does not need to be written in the story syntax, because there is no place to put it. But it should be written in the requirement details/test cases. Well, this is the "batch create users" experience of the Martian products.Syntax of different types of stories Let's try to c
