Infographic: Understanding Debian


Time for another excellent Linux infographic. This one, by Claudio F Filho, explains Debian and it's various versions. It explains the names and purposes of the Stable, Unstable, Testing and Experimental branches of Debian. Something that's not included in the infographic is about Debian's name; it's a portmanteau of the names of the creator of Debian, Ian Murdock, and his wife, Debra. Ubuntu and many other Linux distros are based on Debian, so it may be worth your time to understand it even if you don't use it directly.

If you want to use Debian but aren't confident in you ability to install it, I recommend Crunchbang Linux. They have done most of the work for you, and it's a breeze to install.

Install Oracle Java 7 in Ubuntu 12.10

Installing Oracle Java 7 in Ubuntu can be difficult to do by hand. The Webupd8 team has provided a very easy installer in the webup8team ppa. All you have to do is add that ppa:

sudo add-apt-repository ppa:webupd8team/java

And install the oracle-java7-installer:

sudo apt-get update
sudo apt-get install oracle-java7-installer

You might encounter a few dialogue boxes that ask you to agree to license terms.

All done!

After that, you should be able to invoke Java on the command line with java, or by right-clicking on a .jar in Nautilus and selecting "Open with Oracle Java 7 Runtime".

For example, to run a jar, called jdiskreport-1.4.0.jar, just right click on it in Nautilus:
Or, in a terminal, type:

java -jar jdiskreport-1.4.0.jar
