Build a Python HTTP service We often need to build HTTP services, but we do not want to build complicated Apache and ISS servers. In this case, we can use python to help us build servers. For example, I have previously mentioned how to use python to build XMLRPC for server/client communication. However, there is still a problem here. If I need to display local files (slice ), however, rpc cannot directly access local files. What should I do? In this case, you only need to open a simple service

specific search conditions, such as WHERE clauses have a fine limit or if the unordered result set is returned. However, external fragmentation can have a performance impact if you want to return to scan a clustered index and look for contiguous pages.In SQL Server, a larger unit than a page is a zone (Extent). A district can hold up to 8 pages. A zone is a physical unit that is allocated as a disk. So when a page is split, you need to cut the area multiple times. More scanning is required. Bec

Linux has added swap space-Linux Enterprise Application-Linux server application information. For details, refer to the following section. Today, I suddenly found that the proxy server is unavailable. I went up and checked the squid port to Stop listening and view the log. The following error occurs: Localhost kernel: Out of Memory: Killed process 785 (squid ). There was no valuable result when google made a pass on the Internet. Let's look at it for another reason. Is the linux swap used

For a long time before the frame Sealing Failure of a switch occurs, our network is normal. You can force the super engine to set the Trunk of IEEE 802.1Q. After the network is stable, connect the jumper to the igabitEthernet 3/48 interface. Switch frame Sealing Failure A strange problem occurs in the VLAN of the two Departments in the office area of the organization. Some websites on the Internet can access normally, but some websites cannot access it. emails received through Outlook or Foxmail

Theoretically, this is not necessary, but it seems that there is no other value.Therefore, the maximum disk capacity is:255*1023*63*512/1048576 = 8024 GB (1 m = 1048576 bytes) or hard disk vendor commonly used units:255*1023*63*512/1000000 = 8414 GB (1 m = 1000000 bytes)In the CHS addressing mode, the value ranges from 0 to heads-1, 0 to cylinders-1, and 1 to sectors (starting from 1 ). 2. introduction to basic INT 13 H callsThe bios int 13 H

empty string to a file, as follows:# Echo ""> access. log or # echo> access. logNote: Empty strings are not equivalent to null. A string indicates that it is a specific thing, but its content may be empty, but null means that a thing does not exist. For this reason, when you redirect the echo command output to a file as input and use the cat command to view the content of the file, you will see a blank line (an empty string ).To use null as the output input to the file, you should use the-n opt

That is, each track of a hard Disk has the same number of sectors, resulting in a so-called 3D Parameter (Disk Geometry), that is, the number of magnetic Heads (Heads) and the number of Cylinders) sectors and corresponding 3D addressing methods. CHS Architecture Among them, the number of Magnetic Heads indicates that the hard disk has a total of several heads, that is, the number of disks with a maximum size of 255 (stored in 8 binary bits ); the number of cylinders indi
