The great thing is, author provided all platform installer.
Ubuntu, Debian, Centos, Fedora, even readhat 5,6 and so on.
So great for people lazy to compile by themselves for trying little software.
Good job! I up-voted you!
For programmers or IT related people, you can easily compile kernel 3.12 with in 10 commands. and reboot.It will give you latest kernel.
1. install git.
2. get linux kernel from Linus tree.
3. google how to compile kernel and compile it.
4. restart.
Note: ubuntu will elegantly handle GRUB2 for you.
That means when you reboot, you are able to choose what kernel you want to use.
Try this, and you won't need to wait for UBuntu 13.XX 14.XX for new kernel you want to use.
