It’s almost new year and the urge to upgrade my blog comes back. Well, has been a while since I’m using Octopress and so far was working great, but the lack of updates(I know Octopress 3.0 is coming) and plugins make me wanted something new, I started searching for a replacement, I tried Pelican, Hexo and Ghost.

Create the template file /tmp/template.mustache My hostname is: {{hostname}} My name is: {{name}} Fruits that I like: {{fruits}} Our CFEngine file /tmp/parse_template....

Virtualenv helps a lot when you work with various Python projects or when you have to use specific packages or different Python versions. In this tutorial, we are going to install Virtualenv on Ubuntu 14.04 and configure it on zsh. Install pip, virtualenv and virtualenvwrapper sudo apt-get install -y python-pip python-virtualenv virtualenvwrapper Create the directory for our virtual environments mkdir ~/.venvs Configure ZSH - .zshrc Edit the file ~/.zshrc and paste the content below:...
