Create Boot CD for Openstack

Why?

I got stuck when trying to extend the root partition. The partition table ended up broken and I cannot boot into the system.

Preparation

  • download Hiren Boot CD, it will come in .iso format
  • install syslinux in the system (sudo yum install -y syslinux)

Make the CD image with partition table

The best explanation of Python decorators I’ve ever seen. (An archived answer from StackOverflow.)

NOTE: This is a question I found on StackOverflow which I’ve archived here, because the answer is so effing phenomenal.

Q: How can I make a chain of function decorators in Python?

If you are not into long explanations, see [Paolo Bergantino’s answer][2].

FWIW: I didn't produce the content presented here (the outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.
