In the actual application process may encounter the problem of DNS parsing errors, that is, when we access a domain name can not be completed to resolve the work of the IP address, and the direct input of the Web site IP can be normal access, this is because of DNS resolution failure caused. The probability of this phenomenon is relatively large, so this article will be from the beginning of zero to teach readers some basic troubleshooting DNS trouble
confused with precision. High Accuracy means that the repetition error and system error are relatively small, and the measurement data is concentrated near the true value.

Figures 1 (a) and (B) Indicate the good and bad shooting accuracy, that is, the system error size. Figures 1 (c) and (d) it indicates the precision and difference of th
Currently, the variety of smartphones on the market is vast, and their resolutions vary widely. When developing mobile games, it is inevitable that you will encounter problems of automatic resolution adaptation. A cross-platform mobile game engine I developed some time ago naturally encountered this problem. The engine is named ogl2d.
