Recent research shows that a switch to fiber optic services can lead to substantial savings for broadband suppliers and consequently consumers too. As technology progresses and more internet options become available people are constantly on the lookout for ways they can make savings whilst not compromising the quality of their connectivity.

Before delving further into how fiber optic broadband can lead to cost savings it is first important to establish what this is. Essentially it is really quite simple. Fiber optic broadband transports connection via using copper fiber optic cables. This is in comparison to the other popular methods of utilizing a telephone modem or alternatively a dialup connection.

In this tutorial, I will provide step by step process to setup MySQL replication. We will create one master and one slave. We will use two CentOS 6 servers - one for master and the other for slave. This following steps have been tested on two virtual machines.
Our master server will have IP address 192.168.122.10.
Our slave server will have IP address 192.168.122.12.
You might want to run SELinux in permissive mode.
Perform these steps on the master:
Install MySQL server.
yum install mysql-server -y
Mozilla Firefox has finally launched its own browser-based mobile system, which seems like a credible option for companies emerging with their phones and intending to keep them low-end. For a much savvy audience however, the system is not exactly what they are looking for especially when iOS and Android are still leading the mobile technology market. However, in markets where phones with great features still take up a major market share, Mozilla Firefox combined together with a Blackberry SIM can become successful with its technology. With the promise to improve their system with time to match their rivals, Firefox is all set to attract investors and partners to support it in its venture.
Why Is It Good?
The system is almost similar to that of Android and iOS which makes its use quite simple, especially for those who have some experience of using a smartphone. The familiar app structure presented in a grid form, swiping from left to right presenting different apps is just the same as in iOS. A calling and messaging app, camera and Firefox browser is a permanent fixture at the lower end of the screen. A search app is also available which is quite different from that of the other OS due to the fact that it is a browser-based system. Searching on this app can not only provide results from within your phone but also from the Firefox Marketplace and the Web.
