Wandering around Seoul

I walked around Seoul city area in South Korea sometime back. Those days I didn't have enough time and enough peace in mind to write down a little note about it. I took lot of pictures and the main place I visited was the war memorial museum. Here we go with few selected photos from my camera. War is not something I value much, but aircrafts are obviously something that fascinates me. I saw lot of aircrafts at the war memorial museum. 

 

Using hibernation in Ubuntu 12.04

I missed the hibernate option in Ubuntu 12.04 since its not enabled by default in the system menu. The only option remaining was the suspend option. However, still the hibernate option is available as a command in the terminal.

First its better to check whether its OK to use hibernate command. We need to have equal or higher Swap space in hard disk than our RAM. In my current system, both are 2GB. I checked it from the system monitor application. Since the conditions are preferable, I decided to try the hibernate option. Issue the following command in terminal to hibernate the system.

sudo pm-hibernate

After entering the password, system will be turned off after few seconds. When I turn it on again, it came back to its last state without any problem. So, I hope everything works fine.
