Ubuntu Korean community meeting (August, 2012)

I've been involving Linux world since September, 2011. It's been a year. I started with Redhat and CentOS. Two were Linux OSes which at least familiar with for me and time was passed.


As time goes by, I had to examine new technologies, Openstack for example. I am not intending to blame Redhat and CentOS, those are fantastic systems. However, It was true that deploying, testing is hard working on those OSes for the new technology. In the middle of trying and fail, I realized the existence of Ubuntu.

I've joined in some open communities. Ubuntu Korean community is one of them and I had a monthly periodical meeting yesterday. The post is to review this.

There were the following Agenda of the meeting.
1. To survive as a software engineer in IT era.
2. How to use KDE and its benefits.
3. Introducing commandline utilities
4. CUBRID (Open Database)
