Ubuntu desktop colour switching behind a transparent wallpaper.

A fun little idea I had when I saw a transparent background on deviant art: Why not auto-rotate colours behind a transparent background? I am certain the idea is not original but I wanted to work out how to do it. Here it is:

gconftool-2 -t str --set /desktop/gnome/background/primary_color orange;

So far most common colours work: {red, blue, white, orange, grey, green, yellow, purple}

Enable a transparent wallpaper.

Here is the result:

[Linux] Do you Ubuntu? LiveCD Howto

Ubuntu has grown from strength to strength over the years and linux is fast becoming, if not already, a viable alternative to windows or mac for the average user.

How do you spend most of your time on the computer?
89% Facebook/Social Media, 7% Email/Chat, 3.7% Browsing and 0.3% Excel/Word/Powerpoint... Linux can do that.

Tinkerers should not be Linux haters.
Hack away! Just don't fail. That having been said, if you like to hack and tinker then your Linux system is going to need some extra love when you have borked it. Hackers and tinkerers you have been warned- no names *cough* Ro, Kal, Phil.

Linux?
If you are interested in Linux but have not yet given it a go then now might be a good time to head on over to http://www.ubuntu.com/ and have a look.

Live CD
The live cd feature boots Ubuntu on your laptop or desktop without having to install over your current OS.

1. Following steps 1&2 on this page to download and burn linux to disc:http://www.ubuntu.com/getubuntu/download
2. Ensure BIOS is set to boot from CD as the first entry otherwise the CD will not be checked before your OS is booted.
3. Insert the disc and on the ubuntu boot menu, select "Try Ubuntu without any change to your computer".
4. Enjoy.
Note: Although a LiveCD session is a good way to demo Ubuntu without making changes to a machine, a LiveCD will always be slower than a proper installion that runs directly from a hard-drive (because a CD will always be physically slower than a hard drive). LiveCD sessions are good for:
-a quick 'demo' on a machine before installing/upgrading Ubuntu
-checking if the hardware works as expected
-seeing if you like the look & feel of the distro

Aim: achieve a basic level of home automation by having a low-power sub-system being able to switch more energy intensive systems on and off.

Development Milestones

1st: digitally controlled relay
2nd: serial port control
3rd: wireless control
4th: web interface

The good old days

A picture from the good old days! I hope to be reusing some of these computers to create some dedicated onion routers, file servers, ssh tunnels, webservers etc. Don't worry, I will put Linux on them. I would not trust XP to run as a server. Ubuntu all the way for those that can, and those that can't will take xubuntu or equiv low-spec OS. TBH it might be a case of: the processing power is not worth the electrical power the PC is consuming. So maybe I should content myself to have lots of large metal doorstops instead?
I also need a serial interface electrical switch / relay / control unit so I can bring my 32 port netgear router or a smaller 5 port one online when I need it (or for that matter anything else that plugs into the mains). I wonder if there is already a standard interface for doing such things. If I am not satisfied with what I find, I will make one from scratch as a project.
Back to the servers, I hope to be able to employ WOL magic packets to use the 'Wake on Lan' capabilities of the NICs (Lan Cards) to bring the computers online as and when I need them (to save some more power).
