Use include columns to avoid size restrictions
You can include non-key columns in non-clustered indexes to avoid exceeding the current index size limit (the maximum number of key columns is 16, and the maximum index key size is 900 bytes ). The Database Engine calculates the number of index key columns or index key size hours, regardless of Non-key columns.
For example, if you want to create an index for the following columns in the Doc
uses latin1_swedish_ci. Use the show collation statement to determine the available sorting rules for each character set. This value can be set by using the -- collation_server option when the server is started.

Prototype is a method introduced in IE 4 and later versions for a certain type of objects, and it is particularly convenient: it is a method for adding methods to class objects! This may sound a little messy. Don't worry. I will explain this special method through the example below:
First, we need to first understand the concept of a class. Javascript itself is an object-oriented language

You're Zhu rengong, a formidable hero. after a number of challenging missions, you are finally facing the final boss-a black dragon called Heilong. due to his overwhelming power, you have to plan your actions carefully.

Five IPC $ port used
First, let's take a look at some basic knowledge:
1 SMB: (Server Message Block) Windows protocol family, used for file printing and sharing services;
2 NBT: (NetBIOS over TCP/IP) use the 137 (UDP) 138 (UDP) 139 (TCP) port to impl

I inherited zend_pdf and wrote a static method.
Public static function load ($ source = NULL, $ revision = NULL)
{
Return new dhr_pdf ($ source, $ revision, true );
}
Then an error occurs during access through $ PDF = dhr_pdf: load ($ salespdfpath );
The following error occurred:
Exception 'zend _ end _exception' with message' cross-reference streams are not supported yet. 'In c: \ Users \ n. zhang \ Documents \ tools \ library \ Zend \ PDF \ parser. PHP: 331 stack trace: #0 C: \ Users \ n. zhan
NBT is allowed to connect to the server, the client tries to access ports 139 and 445 at the same time. If port 445 has a response, the client sends an RST packet to port 139 to disconnect, when port 455 is used for a session, port 445 is used only when port 139 does not respond. If neither port responds, the session fails;2. If NBT is prohibited from connecting to the server, the client only attempts to access port 445. If port 445 does not respond,

1) download the corresponding hadoop file from http://hadoop.apache.org/common/releases.html#download( I downloaded version 1.0.3)
2) decompress the file
Command: tar-xzf hadoop-1.0.3.tar.gz
3) test whether hadoop is successfully installed (go to The hadoop installation directory and execute the following commands in sequence)

whether the zone is high-end memory. If yes, continue executing the code after the first line; otherwise, continue to judge the next zone. The zone_start_pfn and zone_end_pfn variables indicate the first PFN in the high-end management zone. The zone_to_nid (Zone) in row 123 returns the node number of the zone, that is, the NID. 124 rows output high-end memory-related information. In row 3, the initialized high-end Memory Page is included in the global variable totalram_pages. Totalram_pages ind
that the UE sends video streams on the local port 3400.
The third parameter RTP/AVP is the transmission protocol, indicating RTP over UDP.
The fourth and fifth parameters provide two types of Net Load numbers.
A = rtpmap: 98 MPV
A = rtpmap: 99 H.261
The corresponding encoding scheme of the Net Load Type 98 is MPV, Which is dynamically allocated.
The corresponding encoding method of the Net Load Type 97 is H.261, Which is dynamically allocated.
