Today, I felt that the programming level down, deliberately practiced, according to the MAC address string, to obtain the MAC address of 2 methods.#include void Func1 (char *str){unsigned char mac[6] = {0};SSCANF (str, "%2x:%2x:%2x:%2x:%2x:%

Excerpt from: http://blog.ibireme.com/2014/09/16/adapted_to_iphone6/Apple's website is designed to show that the ultra-high pixel density of the retina display has surpassed the range of human eyes to distinguish.What effect does retina have on image design (icons, splash screens and all other pixels)? If our app is to support retina, we need to provide high resolution (wide x2, high x2) images. Also, in order to support devices without retina, you still have to prepare a low-resolution version.

image: 1 Replaced with @2x images, the display on the Retina screen is much clearer, and the details are completed. However, in the ordinary screen, the image display needs to be compressed by the browser, some older browsers such as IE6, 7 will display very distorted, while the large size of the picture will occupy more bandwidth, increase the page load time, reduce the user experience. With the help of JS, the pictu

solve the above compatibility issues.To run the previous app, introduce a new concept point (dot). The point concept is important in iOS development, not the developer's attention. The IPhone 4 screen size continues to be x 480, but the units are not pixels but dots.In the iphone 3GS, 1 dots equals 1 pixels. In other words, dots and pixels can be exchanged directly.In iphone 4, 1 dots equals 2 pixels.The screen size of the iphone 4 and iphone 3GS is actually the same, all 3.5 inches. The same p

ARP is used to convert the IP address and MAC address. It specifies the IP address in the LAN where the MAC address is to be obtained in the ARP packet and then sends it to the LAN, the machine with the specified IP address receives and returns an ARP packet, and specifies its MAC address in the returned packet. In this way, the Mac is obtained. The MAC address of the local machine can also be obtained in this way. The following is code implementation. For convenience, I directly used the sendar

How does PHP find the root of a quadratic equation ?. Today, someone has a mathematical question: 4x + 1x2. how much is x. Converting the equation, 4x2 + 12x, and then 4x2 + 2x + 10, is actually a problem of the unary quadratic equation. For a long time, no one has a mathematical problem today. 4x + 1/x = 2. how much is x. Convert the equation to 4x2 + 1 = 2x, and then 4x2-
