When writing a PHP program, some code is used to process some transactions, such as database operations and mathematical operations. Other code is only displayed as the result of transaction processing, for example, some PHP code that uses echo statements to display results in HTML format on a Web browser and the HTML code that directly embeds the PHP program. First, we should clearly distinguish the two types of code, the former is called the background program, and the latter is called the fro
Java/C ++ socket class
If you need to do socket communication between a Java and/or C ++ programs, you 've come to the right place. I 've developed a fairly basic class that can be used to communicate between Java applications and C ++ programs via a socket connection. there are client and server classes for both Java and C ++, so you can use these classes for communication between the same language or
Sometimes you install programs on your computer, but you don't want these programs to appear in the Add or Remove Programs list in Control Panel, so how do you do that? Today, small knitting to introduce the solution.

At present, many units in the system transformation and upgrading, faced with the development of various independent departments of the application of the database unified to adapt to the needs of large concentration of data, to facilitate future data mining and other high-level applications. In the process of database unification, how to transform the existing program based on heterogeneous database quickly and efficiently, e

Use GDB to debug programs and gdb to debug programs
GDB (GNU Debuger) is a powerful Debugger in Linux. GDB allows you to view the internal structure of the program, print the variable value, set the breakpoint, debug the source code in a single step, modify the variable value during running, track the path, switch the thread, and display the assembly code.Compile
To use GDB for debugging, you must add the
Simulate your database carefully
Program Have you found that database data is frequently read repeatedly during computing (especially during multi-user computing ?! This is the primary killer of database processing program performance.
Some people say that before writing a programAlgorithmMake sure that the data records are read in batches and at one time. However, this is often not possible because complicated programs are close to the logical p

Is to write a short program, print your own code. In my understanding, metadata or file operations should not be used here. You must use the program code to generate a string exactly the same as your own code. I have written several versions, and the results of these programs are printed with the Code itself. You can try it and entertain yourself.

), SendMail is the program that the hacker focuses on, because SendMail is running as root and the code is large and prone to problems.
Almost all Linux distributors use SendMail as their default configuration, with only a handful of postfix or qmail as optional packages. However, few Linux distributors use SendMail on their mail servers. Both SuSE and red Hat use a qmail based system.
SendMail does not necessarily have to be completely replaced by other p

In some cases, you must use the console to print logs for debugging programs that are not in the console program. You can use the following class. Rough writing,
