seen from three dimensions of r,g,b.1.1.2YUVThe importance of YUV color space is that its luminance signal y and chroma signal u, v are separated. If only the Y signal component does not have a U, v component, then the image represented here is a black-and-white grayscale image. Color TV using YUV space is precisely to use brightness signal y to solve the compatibility problem between color TV and black and white TV, so that black and white machine can also receive color TV signal .The Y lumina
virtual machine and install BT5. We will not talk about the installation process here. It is certainly not a difficult task for FreeBufer.
To make our VulnVPN work properly, we need to install the following three packages:
1. openswan2, xl2tpd3, and ppp
The installation command is as follows:
apt-get install openswan xl2tpd ppp
After the installation is complete, the environment required for the attack will be ready. At this time, we start the downloaded VulnVPN, and we will not modify it a

The subject requires 4 kinds of traversal for a given binary tree. function Interface Definition:
void Inordertraversal (Bintree BT);
void Preordertraversal (Bintree BT);
void Postordertraversal (Bintree BT);
void Levelordertraversal (Bintree BT);
The bintree structure is defined as follows:
typedef struct TNODE *pos
In this article we will implement the buffer of the loopback server. The implementation of buffer The previous section mentions that non-blocking IO must have buffer. Once again, describe the design of the buffer: One thing to add here is that Writeindex points to the first position of the free space. There are three important invariant expressions :
1.0
2. Writeindex–readindex is the number of bytes that can be read from buffer
3. Buffer_size–writei

3 Cellular IP and mobile IP
There are two main technologies for using TCP/IP protocol for mobile users: Cellular IP Mobile and mobile IP. In this paper, we will discuss the working principle of Bluetooth technology separately.
3.1 The concept of cellular IP (cellular IP) Working principle
TCP/IP is designed under the assumption that the terminal device is fixed,
