How small is the sun down there!

I saw this wonderful movie taken from Mars Rover Opportunity.

The most incredible thing to my eyes was how small is our sun viewed from down there. Looks not so bigger than other stars, but its light is still so strong to bring day light to te whole planet.

How to make gwibber open Firefox (or any other browser) instead of the default one

Since I found Gwibber installed by default with my Ubuntu 10.10 os, I started using it  as my Social broadcast messages client, and I really enjoyed this way to stay informed about anything.

The only annoying thing about this brilliant piece of software was the fact that the links were opened with Epiphany instead of Firefox, that is my default browser.

I googled a little until I found the solution here.

Here is all you have to do to fix this problem:

1) install galternatives

sudo apt-get install galternatives

2) Change the values of these configurations:

gnome-www-browser
x-www-browser

Now gwibber opens the links in the browser you want. Perfect for me
