But containerization technologies like Docker, as much as they are cost effective in terms of memory and processor power, have a learning curve which while not too steep, do require a good chunk of time to be spent on learning. That’s why older virtualization techniques like VirtualBox are still being used to create environments for development and QA teams. And yes, they are quite effective!
This short tutorial will show you how to setup one of the little intricacies when developing in VirtualBox, namely being able to store and edit your code in the host machine, while running it inside the guest OS. Will be using CentOS 7 as a guest, while the host is not of any importance.

For some time I’ve been a fan of NPR (npr.org) hosted radio shows and podcasts. But recently I’ve stumbled upon one of their jewels which I found to be extremely beneficial. It’s called “How I built this” and each episode includes an extraordinary story behind a successful business or movement told by the (wo)man whoRead more about Each successful business has a great story.
