Ubuntu Hardy Heron (8.04)
November 30th, 2007 by khermans
Ubuntu's next LTS release date is not scheduled until April of 2008. However, you can test drive what the future will look like today. Follow these simple steps to upgrade your existing Gutsy Gibbon installation to Hardy Heron! I always run what is known as "ubuntu+1" immediately after the first Alpha release is finalized, which occurred today. I am happy to say that the dist-upgrade went smoothly and all is well :-)
$ sudo sed -i "s/gutsy/hardy/g" /etc/apt/sources.list
$ sudo aptitude update
$ sudo aptitude dist-upgrade
All done! If you run into any issues, join the #ubuntu+1 channel on Freenode's IRC server...

In case you were wondering about the fun side of Linux World Expo, we thought we'd give you a peek at our shenanigans. We at Linux Journal love what we do so much, that we can't help but have a ball wherever we go.
The X Window System is a magnificent platform for many uses, but using it to run an application over a slow network is nearly impossible. This is an introduction to NX, a technology that makes remote applications fly even over commodity internet.

Feeling a bit like a Thermian? Never give up, never surrender! Someday, you could go from underdog to top dog. Just take a look at a few of the underdogs we highlight in this issue: Mutt, djbdns, Nginix, Gentoo, Xara and the program voted mostly likely to fail just a few years back—Firefox. If Firefox not radical enough for you, check out Chef Marcel's column for some more alternatives. Having trouble mapping your program data to your relational database? If so, Rueven Lerner shows you some tricks in his At The Forge column.
Need to run GUI applications on your server in the next state? In his Paranoid Penguin column, Mick Bauer shows you how to do it securely. Kyle Rankin keeps hacking and slashing and shows you a few split screen secrets you may not be familiar with. Finally, we all know what happens next February, but only Doc knows what happens afterward.
