I know this is off topic, but if you look at this site using your Linux machine then it's close to the topic? ! ;)
However, this is a really great photo of the earth at night. http://antwrp.gsfc.nasa.gov/apod/image/0011/earthlights_dmsp_big.jpg The image is a panoramic view of the world from the new space station. It is a night photo with the lights clearly indicating the populated areas. After enlarging the picture, you can scroll East-West and North-South. Note that Canada's population is almost exclusively along the U.S. border. Moving east, to Europe, there is a high population concentration along the Mediterranean Coast. It's easy to spot London, Paris, Stockholm and Vienna. Check out the development of Israel compared to the rest of the Arab countries. Note the Nile River and the rest of the "Dark Continent". After the Nile, the lights don't come on again until Johannesburg. Look at the Australian Outback and the Trans-Siberian Rail Route. Moving east, the most striking observation is the difference between North and South Korea. Note the density of Japan! . What a piece of photography. It is an absolutely awesome picture of the Earth taken from the Boeing-built Space Station last November, on a perfect night with no obscuring atmospheric conditions.
