root access in Ubuntu

sudo -i
Sometimes I get tired to type before every command sudo and sudo -i helps me in that case. Sure I can make a normal root user by just only command passwd without any parameters but ubuntu/debian people constantly remand me that is not a good idea so I will not do that.

flash player 64 bit in Ubuntu

sudo apt-get install chromium-browser flashplugin-installer

I don’t really need the flash player but the message “missing plug-in” makes me anxious so I remove Chrome and install Chromium.
