Set Up Sudo: Escalate Privilege Without Using SU

I've been using Arch Linux now for more than a year and all that time I have not set up sudo. Sudo is a better way to perform root jobs without logging in to your root account. Among many benefits of sudo is that once you're finished with your business it drops the privileges back to normal. You can also specify which users can perform what actions.

Download the sudo program.
$pacman -S sudo

The configuration file for sudo is the /etc/sudoers

Warning: always use visudo to edit /etc/sudoers.

Which means don't open /etc/sudoers with an editor? not really. You can set visudo to use your favorite editor. For example vim, nano, gedit.

#to set visudo to use nano and open a default sudoers file
$ EDITOR=nano visudo

#add a user (you perhaps) to do root activity
USER_name ALL=(ALL) ALL

Read about all the options available for sudo in this Arch wiki.
Read the sudo manual.

Appindicator In Natty Ubuntu 11.04

Previously ranted about the blind alley Ubuntu 11.04 seemed to be leading us when it comes to some applications not being ready yet for the dropping of system tray. What I should have done is press on. There are posts about editing a white list with a recommended GUI tool to help us out here , here and here . Like everything in Linux, there's a configuration file for it, if you can find it and if you have the inclination to go ninja. If not then there's dconf-editor. Download dconf-tools from Software Center. Navigate to desktop>unity>panel. Add your application in the white list. Then close the window. No save button. mmm. So far I have added Shutter, Dropbox and Keepassx in the white list. Before... After.

Evolution Mail on GNOME 3.26

There's a slight change in the user interface. A To Do column now appears to the rightmost after the GNOME 3.26 update. Also there's a noticeable stability increase, what with goa-daemon stopping its RAM usage creep. I don't have to kill it every couple of hours.

New Converge ICT Plan Max with Sky Now

I pulled the trigger on Converge Max plan 400Mbps with Sky channels. I went to their sales office and asked for the upgrade. No charge at all and they didn't ask me to return the old modem. It looks like they will pull it when they install the new modem.e It came with a black box for the TV. The configuration is easy but it took me 3 days to figure out the Wired connection. It should be fine except I have to jiggle it in the config (GUI). Turn 802.1x on and off to finally connect. Here's the speed for the Wired connection:
