-end port of the FTP server through the firewall. Many clients in the intranet cannot log on to the FTP server in port mode because TCP 20 from the server cannot establish a new connection to the internal network's clients, causing it to fail to work.35.3.6 goals and disadvantages of FTP implementationThe objectives of the FTP implementation are as follows: Promote the sharing of files (computer programs or data). Encourage the use of remote computers indirectly. The details of

Three.js is a great open source WebGL Library, WebGL allows JavaScript to manipulate the GPU, realizing the true meaning of 3D at the browser end. But at present this technology is still in the development stage, the material is extremely scarce, the amateur learns basically to through the demo source code and three.js own source code to study. Foreign website Aerotwist.com has six simple introductory tutorials, I try to translate them, and share with you. I used three.js in some of the experim

The default section block is optional, but including the default block is a good programming habit, just in case. In this script, there is no need to execute the code, because we should not be able to enter the default part.9. }This right curly brace ends the switch statement.The above is a small example of the book, the entire example of the book is this look, basically is a line of

C + + is a hybrid programming language, which can be programmed by program design method for various purposes. It does not abandon the practical characteristics of efficient operation, but also strives to improve the programming quality of large-scale programs and improve the problem-description ability of programming language.

Only two references point to the same object, and the two references are equal.Type conversionsBecause of the weak type of
