In order to later less detours, write down their own dull footsteps.The first time you install OpenStack, the server you get is a Redhat6.5 system with a CentOS6.5 system disc in hand.

whether the current block is an intra-frame block in advance, however, the dynamic variability of video images makes it difficult to predict the threshold. In view of this, this paper proposes a new method for measuring the prediction direction. In H.264, rdo technology is used to traverse all intra-frame prediction modes and select an optimal prediction mode. The prediction mode of intra-Frame Prediction blocks does not directly perform entropy enco

Data MSDE Summary If developers want to create desktops or shared database applications, and plan to expand the functionality and scale of these database applications in the future, using MSDE as a data engine will have the following advantages: In the near term, the development costs of the system can be reduced, and in the long run, also provides the most convenient way to migrate a database application that is currently created. When the size of your organization expands to provide new requi

The Access database is often used in some small system programs. To increase the security of the information in the database, the simplest way is to add a password to the access file (of course, you can also encrypt the data in the database and store it in the file to protect the data, but this method requires you to consider encryption and decryption in the program.) What about accessing a password file through a database connection string? Below are some solutions I have found on the network.
