Hard Links vs Symbolic Links
I always forget this symbolic link vs hard link difference. Here's a blog entry with examples so that I won't forget again.
Setup

Hard Link

Symbolic Link

The Questions
What is the difference between the two types of links other than the -> in the image? :)
Hard Link is like giving another name to the same file content. So a file content is actually deleted when all hard links are deleted. That is all the names.
Symbolic Link is on the other hand is like a shortcut to another file. When that file is gone, the link is broken.
The Great Destruction
