Today, the installation of Coreseek 3.2.14 under CentOS is configured to search for results under commands, but in PHP it is not possible to connect to the search server with the following error message:
Connection to 127.0.0.1:9312 failed (errno=0, msg=)
Toss for a while to find the cause of the error, is because I installed the LNMP one-click installation package, php.ini disabled some functions, including Sphinx API required a function Fsockopen

After Vista, the debug information can be output conditionally using dbuplintex or kdprintex. (The previous 2003 Server or XP is an unconditional output, which needs to be encapsulated and set the debug information level)

I. Introduction There are two main types of Message Queues: POSIX message queues and System V message queues. System V message queues are currently widely used. Considering the portability of applications, newly developed applications should use
Message Queuing
In the SYSTEMV version of UNIX, At&t introduced three new forms of IPC functionality (Message Queuing, semaphores, and shared memory). But the BSD version of UNIX uses a nested interface as the main form of IPC. The Linux system
The examples in this article describe the three ways in which C # implements sending messages. Share to everyone for your reference. The specific methods are analyzed as follows:First, the question:Recently due to a ri; project needs, user requirements in the purchase of products or shipments and other links, need to send an email alert or every Monday to let the system automatically collect data sent an e-mail, so I also find relevant information, wrote a demo to share to everyone, we learn tog

Background
Suppose we want to develop a producer-consumer model of code, a routine responsible for production data, a routine responsible for consumption data, the code is as follows:
Error code
type MsgStru struct { msg []int}var msgChan chan MsgStrufunc sendMsg() { buf := make([]int, 10) for i := 0; i
The expected output should be 0 to 9 in order, but actuall
Speaking of Blockingqueue, we are most familiar with the application of producer-consumer mode. However, if the upper-level code that calls the queue adds a synchronous block, the thread is deadlocked.For example: StaticblockingqueueNewLinkedblockingqueue (); /*** Sync Lock*/ StaticObject lock =NewObject (); Static voidproducer () {synchronized(lock) {Queue.put ("1"); } } Static voidCosumer () {synchronized(lock) {//once blocked, the current thread is suspended, the lock lock will ne
length; // message length
Char msg [5]; // message content
} Msg_struct;
Sending implementation process: 1. determine the number of complete messages by dividing the total message length (that is, the total length of the main function parameter) by 8.
2. Send a message by calling the sendto function once, and obtain the destination address based on the data structure to determine the sending path, that is, judge every 8 bytes, the destination address
The "system. net. Mail" provided in. NET Framework 2.0 can be easily implemented. This article lists three methods for sending:1. Use localhost;2. Use normal SMTP;3. SMTP over SSL;
For example:
1. Use localhost
Public void sendmaillocalhost ()
{
System. net. Mail. mailmessage MSG = new system. net. Mail. mailmessage ();
MSG. to. Add ("a@a.com ");

Recently, due to the needs of an R I project, users require that the system send an email reminder or send an email every Monday to automatically collect data, therefore, I also found relevant materials and wrote a Demo to share with you, so that everyone can learn together.The "System.
