Leopard on my Macbook
The DVD-ROM of my Macbook is broken, damn it!
I used Tiger since 2006. Although Leopard was released back in 2007, I was so reluctant to upgrade my operating system. So I start getting old, huh~
Today I installed Leopard on my Macbook. Actually the installation process is much easier than I expected, even with a broken DVD-ROM.
Nice to meet you finally, Leopard!

One observation on software installation on ubuntu
There are many ways to install softwares on Ubuntu. However, I think that the best one is install them through its .deb packages. In this case, the system knows what packages you have and what you don't have, therefore your package dependence is consistent.
For example, I had the Gutenprint package of version 5.2.0. I have a new print which is supported by Gutenprint 5.2.3 but not Gutenprint 5.2.0. In the very begining, I download the .tar.gz package of Gutenprint 5.2.3 and install it. But the CUPS didn't recognize the newly installed version. Then I uninstall it and downloaded the .deb file and installed it. Everything is fine right now. I can see the driver for my new printer in CUPS.
BTW, I tried Qt4.5 on Ubuntu. I didn't find the .deb package for Qt4.5 so I installed it through .bundle file. It seems that there are several linkage problems with Qt4.5. Althgouth I fixed them later, I recommend to install qt4 through apt-get. In this way you will install Qt4.x (x is less than 5). Although it's not the latest version, you will find that it's easier to handle so you can focus on your own programs.
