Society where everyone live in happiness. The five principles of our national life. First, believe in God . Second, nationalism . Third, humanity . Fourth, democracy . Fifth, social justice .

I got a problem when I wanted to create a field in a database table which field type is DATETIME and default field value is CURRENT_TIMESTAMP. I run a server on Ubuntu 12.04 and MySql 5.5. I found that MySql 5.5 doesn't support that statement. So, I must upgrade my MySql server to MySql 5.6.  Then I read some articles on internet. Most old articles said that we must download and install MySql 5.6 manually from official site because Ubuntu 12.04 doesn't have any repository for it. But, this day Ubuntu 12.04 has launched PPA for MySql 5.6. So, what you should do is just to remove your old mysql-server, update your repository, and install new one.

Pictures below show you the difference. SVN scheme Git scheme You can use Git with some tools such as command line tools and desktop client applications. In this post, I will only show you how to use Git with Eclipse.

Latest version of VirtualBox (4.3) has some new features whose every users wants. Two features which I really love are shared directory and shared clipboard (clipboard copy). By using shared folder feature, we can create some directories on host operating system which can be shared with guest operating system. Guest operating system can read data from the shared directory or write data to it so that host operating system can write or read the data. By using shared clipboard feature, we can copy some text data from host OS clipboard to guest OS and otherwise. To use that features, we need some proper configuration process before and while running our virtual machine. I noted some points that is important and I hope we don't need to waste much time on configuration.
