how to update github page in multi pos

0.0.1. Requirement

I want to write blog with github page and octopress in the office
and in the home.

0.0.2. Steps

The github page has work well done with pc in the home.
Now setup the environment in office to write github page.
The github page repo:
https://github.com/martinbj2008/martinbj2008.github.io

the octopress is pushed to git repo as branch “source”

How to write blog and sync them to github while avoid conflict with home?

0.0.2.1. 1. clone the ‘source’ branch of github page repo.

The branch includes markdown files and config files.

git clone https://github.com/martinbj2008/martinbj2008.github.io blog
cd blog
git checkout -b source origin/source

0.0.2.2. 2. fake _deploy directory to avoid rake deloy failure.

clone the github page repo and checkout branch `master`

git clone git@github.com:martinbj2008/martinbj2008.github.io.git _deploy

0.0.2.3. 3. setup octopress

install dependencies.

sudo apt-get install rbenv
sudo apt-get install ruby
sudo bundle update rake

gem install bundler
rbenv rehash    # If you use rbenv, rehash to be able to run the bundle command
bundle install

Install the default Octopress theme.

rake install

0.0.2.4. 4. enjoy it.

rake generate
rake preview
rake deploy

0.0.3. Solved Problem

0.0.3.1. 1. rake could not work.

sudo bundle update rake

0.0.3.2. 2. rake version does not match, need edit Gemfile.

This work has been done in the home.
