The local clock in the Xen Linux machine is by default (done) synchronized with the physical host clock, in order to change the time it uses the Sync Service for NTP, the kernel parameters must be set by the virtual machine:Shell CodeEcho 1 >/proc/sys/xen/independent_wallclock
The/etc/sysctl.conf configuration file in the virtual machine adds the following two and takes effect after reboot.Config code# Set Independent Wall clock timeXen.independent_w
In some server architectures, you will experience file synchronization issues, such as a site mirroring backup, synchronization of files to multiple CDN nodes, and so on. There are two main issues that need to be addressed
1. How to implement file synchronization problem? 2. When do I perform a sync operation?
File synchronization can be used Rsync+ssh, when to synchronize their own operation? Maybe some people would think of Cron, this is true, can
RTP and Rtcp explain. Include sync timestamp
RTP is real-time transport protocol abbreviation, is designed to transmit streaming media data, has a wide range of applications, other related to the introduction of their own to see the RFC, I do not intend to discuss these boring conceptual things.
(1) Understanding RTP
It can be said that the RTP protocol does not rely on the underlying protocol, that is, it is an independent protocol. In general, bec
Micro-letter and QQ space synchronization we want to micro-letter and QQ number is bound to be able to oh.
1. In the mobile phone we open the micro-trust Circle of friends to enter, as follows
2. Then find the following "to remind who to see" under the "QQ Space" logo, details as shown in the following figure
3. Then we will see that there will be a "QQ space" logo lit to open sync
4. Now we click "Send" to achieve micro-

Step 2: We click on Iphone6 Plus in the upper right corner and click "Summary" now select "Manage music and video manually" in the interface and click the "Apply" button in the lower-right corner.

Briefly in the previous article about the ES synchronization data script roughly, but the actual situation is certainly not as simple as the script in the previous article. For example, I now have three tables, two entity tables, and an association table. The approximate implementation is as follows:The bin directory establishes a Statefile.json file:{ ' type ': ' JDBC ', "Statefile": "Statefile.json", "JDBC": { "url": "jdbc:mysql://", "User": "", "Password": "",
