These replace the dump and load statements in earlier versions of SQL Server.

Microsoft's Mobile Developers Conference was held in Beijing in June, and while domestic mobile apps are just getting started, the broad prospects are being watched by more and more software vendors. Commercial applications on mobile devices, although just beginning, have shown great potential for growth.
In the Microsoft Mobile Development Challenge, my work, "glut

In the previous six articles, I have introduced in detail the algorithm related to the lexical analyzer. They are more concerned about the implementation of the details, the feeling may be more messy, this article on the overall description of how to define the lexical analyzer, and how to implement their own lexical analyzer.
The second section is a complete de
Last time, we talked about the contextual language used in syntax analysis, the generative formula used to describe contextual grammar, the generative derivation, And the syntax analysis tree. Today, we will discuss how to compile a syntax analyzer. The method described today is calledRecursive descent(Recursive descent) method, which is a method suitable for handwriting syntax compiler, and very simple. The recursive descent method has some limitatio
We can use the network protocol analyzer to observe the network protocol analysis. Here we will explain the network analyzer. The best way to analyze data packets transmitted over the network depends largely on the device you have. in the early stages of network technology development using the Internet era of HUB or HUB), the answer is very simple. You only need to insert the line on a HUB, and everything
The routing protocol analyzer is still very important in routing applications, and the technology is gradually improved. The best way to analyze data packets transmitted over the network is largely determined by the device you have at hand. In the early stages of network technology development using the Internet era of HUB or HUB), the answer is simple. You only need to insert the line on a HUB, and everything is done-that is, use the routing protocol
I recently planned to redo a previously unfortunate job. One of the small tasks was to write a simple SQL syntax analyzer.
My undergraduate course "compilation principles" rarely leaves some images in my mind. In the original course, I wrote a compiler called dicuf (which seems to sound like this). Under the spur of an evil Ta, we used Lex and YACC to successfully escape from the terror. Now we have to pick up compilation again, which is still somewha

Connect Android devices to Unity Profiler Performance Analyzer
Unity provides two methods for developers to connect Android devices to Profiler for performance analysis:
1. The Android device and computer are in the same Wlan through wifi.
2. USB ADB
Generally, our computer is a network cable, so we use ADB. ADB is more responsive to device performance than wifi.
The official English documents are as follows:

Unity provides two ways to enable developer's Android device to connect to the profiler for performance analysis:1, through the wifi,android device and the computer in the same WLAN.2. Via USB ADBIn general, our computers are wired, so we use the ADB approach. Compared with the WIFI,ADB also more timely reaction equipment performance.The official English documents are as follows:Http://docs.unity3d.com/Manual/Profiler.htmlFor ADB profiling, follow these steps:attach your device to your mac/

Sometimes we often count the number of words in an article. At this time, we need a word frequency analyzer to solve this problem.
Basic Idea:
First save the string in the file or input by the user, and then scan backward from the first character. When a letter is encountered, add it to a string first, and then scan backward, if the character string is still a letter, it is connecte
Before IBM launched the world's first personal computer in 1981, computers were used in commercial or industrial use. With the birth of IBM 5150, personal computers have truly entered people's work and life, but also marks the beginning of a new era-the personal computer era.
In the next thirty years, with the development of computer and network technologies, personal computers have developed towards a more intelligent, portable, and easy-to-use trend. The advent of the portable laptops, PDAs
