I. scrapy Introduction
Scrapy is a fast high-level screen scraping and web crawler framework, used to crawl websites and extract structured data from their pages. it can be used for a wide range of purposes, from data mining to monitoring and automatic testing.

Method 1:
Go to the MySQL installation directory and open the MySQL configuration file my. ini or my. CNF to find max_connections = 100 and change it to max_connections = 1000 to restart MySQL.
Method 2:
The maximum number of connections for MySQL is 100 by default. Client Logon: mysql-uusername-ppassword
Set the new maximum number of connections to 200: mysql> set global max_connections = 200
Display the currently running query: mysql> show processlist
Display Current status: mysql> show status
IntroducedWe have developed a tax calculator, after entering the salary, printing the tax payable.A tax calculation formula:
Taxable income = Salary amount-Various social insurance costs-starting point (3500 yuan)
Taxable amount = Taxable income x tax Rate-Calculator deduction
Each of the social insurance costs we set in this procedure is 0, do not consider.The tax rate and the Calculator deduction number corresponding table:

Recently established in the lab's network environment, all host labs are connected via a switch. Want to be a gateway through the server (single card), using the Mentohust authentication extranet, and then other hosts in the intranet through this gateway to connect to the external network.1. First use mentohust on the server to connect to the extranet, and then enter the Ifconfig command at the terminal to view the acquired extranet IP:Eth0 Link encap: Ethernet Hardware address B8:AC:6F:D8
MTU is the abbreviation of Maximumtransmissionunit, is the largest packet of packets on the network, most network device MTU is 1500,MTU unit is byte, if the MTU of the machine than the MTU of the gateway, large packets will be removed from the transmission, This will result in a lot of packet fragmentation, increase the packet loss rate, reduce network speed.
By setting the MTU of this machine to be smaller or the same than the MTU of the gateway, t
Copy Code code as follows:
$ (function () {
var $inputs = $ (' Input[type=button] ')
. Delay (500)
. Queue (function () {$ (this). Hide (). Dequeue ();})
. Delay (1500)
. Queue (function () {$ (this). Show ();});
});
The above code lets the button in the page Hide 500 milliseconds after the page is loaded, and then displays it in 1500 milliseconds.

Internet. In fact, the optimal MTU value in a LAN depends on hardware, software, and wireless interfaces.In one case, modifying the MTU size can make the device work well, but it may cause performance and connectivity problems in other aspects.When devices with different MTU values communicate with each other, the information package will be divided into multiple devices for transmission to devices with the smallest MTU value.Windows XP automatically sets MTU. In other words, MTU optimizes the
Delayed execution is quite useful in some special cases, and the implementation method is also very simple. This article provides a good example. If you need it, you can refer to it and hope to help you.

How can this problem be solved? I found some information on the Internet for half a day and said I should modify my. for cnf, it is said to modify safe_mysqld and try again. The former is useless,
