Execute sudo without Password?
Inspired by this question.... I am the sole person using my system with 12.04. Every time I issue a sudo command; the system asks for the user password (which is good in its own way). However I was thinking; without activating the root account; how can I execute the sudo commands which will not ask for user password to authenticate. NOTE: I want to execute sudo command without authenticating via p

automount - How to make partitions mount at startup? - Ask Ubuntu
How do you make HDDs and partitions mount at startup on Ubuntu? I always keep my media and data files on separate partitions - one 2tb HDD and a 400 odd gig partition. I have been trying to swap the default folder location for the home directory to my other drives. It works when I change the /home/user_name/.config/user-dirs.dirs file to the directories I want, but only until I reboot the system.

I frequently ssh into my box at home from school, but usually when I change classes and my computer suspends, the pipe will be broken. However, ssh simply locks up - Ctrl+c, Ctrl+z and Ctrl+d have no effect. It's annoying to have to restart my terminal, and even more annoying to have to close and re-create a new screen window. So my question, is there an easy way to make ssh die properly (i.e. whe
How do I change the default shell used in Byobu (tmux)?
I've become addicted to Byobu and I've recently shifted from bash to zsh; Now I want to combine the two, however I have a one initial pre-requisite: I cannot make zsh the default shell for my user as it's a shared account and the rest of the team aren't as zsh happy as I am - That rules out the 'chsh -s /bin/zsh' option. So, I discovered you can set a default-shell for tmux (which should follow ac

How to upgrade to the latest Emacs?
I have Emacs 24.3.1 and I'd like to upgrade to the latest Emacs 24.4.x. All documentation that I have visited suggests building from a tarball or source.
