Q What is the best way to back up an Ubuntu machine? I basically want a complete backup of my internal hard drive, where if for any reason the internal hard drive fails I could simply replace it and restore from my backup.
A Déjà Dup is preinstalled in Ubuntu, and it's a sound choice. There are online tutorials on how to use it. If you want to make a full image of a hard drive, use Clonezilla. The two can be used together: for example, take an image of the hard drive as of Dec. 31, then take a backup of the entire Home folder as of Jan. 31, and then weekly “incremental” backups of all the files which have changed.
Q Is there a command I can use to stop my computer from suspending or turning off the screen?
A Yes: xset -dpms
You might want to experiment with other parameters, to see what they are: man xset
Q When will the next Long Term Support release of Ubuntu be available?
A It's scheduled for April 17.
My personal preference is to wait a week or two after an LTS is released, then play with a Live USB, and finally do a fresh install onto my hard drive. I have separate root and home partitions, so if I specify everything properly during the install, my data is preserved – but also see the “backup” question above!
Q I am trying to install this theme from ubuntuthemes using MyUnity and it does not look like the screenshot?
A (Thanks to 3rdalbum in the Ubuntu Forums) Themes only affect the look of the window borders, title bars and the look of buttons, scrollbars, checkboxes, etc. Anything else you see in a theme like docks, desktop backgrounds, information displayed on the desktop, etc, are other things you would need to install.
To fully apply a theme, you do need to log out and log back in again. Until you log out and log in, some of the colors will be wrong.
Q I want to edit my website. Which tool can I use in Ubuntu?
A (Thanks to spectatorx in the Ubuntu Forums) For just HTML and CSS editing, my personal favorite editor is bluefish; you can find it in the Ubuntu Software Center. I also use it for some basic PHP and a few other languages.

Tips and Techniques
More info?
If you're asking for help, the most important thing you can do is provide relevant information about your system. There's a new kid on the block when it comes to system information programs: inxi.
The program has many options. To learn about them, open a terminal window and enter the command:
inxi -h
It's really a two-dimensional result, as -v modifies the other parameters – plus the specialty options such as -h.
I'm delighted to see new system-information options. Does inxi unseat the defending champion? Not yet. To get the most, nicely formatted information, I still use these commands:
cd Desktop
sudo lshw -html > config.htm
The file config.htm appears on my desktop; I double-click on it, and the information appears in my default browser – in great detail. However, inxi will tell you about temperatures, and that's one of my hot buttons.
Remote Desktop Update
I recently wrote about Remote Desktop. Since then, I have switched to a different Remote Desktop client, KRDC. It's graphical, and it makes it easy to connect to any of the recent connections.
If you have never installed any KDE applications, it might install a large number of dependencies – a small price to pay to get the KRDC goodness.
