Actually I am fresh to Write Blog with Octopress in Github Pages.According to the Introduction .And now I have make it avaible and the website is present. However I have suffered some problems when I did the setup.Here is a summary of what I have sufferd and how I resolved.
Could not find rdiscount-2.0.7.3 in any of the sources Run bundle install to install missing gems.
source ~/.rvm/scripts/rvm
rvm use 1.9.3 --default
I have used rake preview ,But I got 404 when I open the http://127.0.0.1:4000
[[email protected] octopress]$ rake preview
Starting to watch source with Jekyll and Compass. Starting Rack on port 4000

As the above information and all the sources are outputed in public/ folder And the following are a part of my _config.yml file
# If publishing to a subdirectory as in http://site.com/project set 'root: /project'
root: /
permalink: /blog/:year/:month/:day/:title/
source: source
destination: public/
plugins: plugins
code_dir: downloads/code
category_dir: blog/categories
So compare the two piece information and check the output dir and is public or a subdirectory in public folder.If your outputdir is a subdirectory you should use this link http://127.0.0.1:4000/yourSubDirName P.S.This is the help from StackOverflow http://stackoverflow.com/questions/17465404/rake-preview-not-working-in-octopress
I will keep record about this topic becuase I am making friends with Octopress in Github Pages
