tasks = Task.select
This only requires memory to store an extra column, with an array tag. No wonder it's 3 times times faster.
2.2.2 Data collection
I say the data collection any code to summarize or analyze the data. These operations can be summarized simply, or some more complex. Take group rankings for example. Suppose we have an employee, Department, payroll data set, we want to calculate the employee's salary in one department rank.

0x00 PrefaceThe static disassembly King, without a doubt, IDA Pro, greatly reduces the threshold for disassembly, especially the excellent "F5 plug-in" Hex-rays can restore the assembly code to a C-like pseudo code, greatly improving readability. But personally feel that "F5 plug-in" can only be used as an auxiliary means, after the combination of dynamic debugging and static analysis, understand the whole

Thank you moderator, I follow this, and then the browser output is and txt text as shown, but if you want to insert into the database what should be done?
I have four fields in my database, Id,name,time,bak.
The first one is ID is auto_increment
All three of the remaining fields are varchar
Now the TXT file is in the format of

Third, IP load Balancing
IP load Balancing is a load balance based on a specific TCP/IP technology. such as NAT, DR, turning and so on. Is the most frequently used way. IP load Balancing can use hardware devices, or you can use software implementations. The main products of hardware equipment is F5-BIG-IP-GTM (referred to as

2.2.2 data set
Any code in the data set that I am talking about is used to summarize or analyze the data. These operations can be simply summarized, or more complex. Take group ranking as an example. Suppose we have an employee, department, and salary dataset. We want to calculate the employee's salary ranking in a department.

If you don't talk much about it, paste the Code directly. The specific code is as follows:

If a network program specifies a port number of 3900, the packet sent by another network program must indicate that the recipient's port number is 3900, and the computer will receive the port number in the packet after the data is reached.
