[python] Generate ranges from items

Some years ago, I added a script for updating headers for (C) in the python files I was developing for Risu. In this way, the header got the list of authors and years working on the files updated automatically. With the pass of the years, the list started to became a bit too long, so I worked on creating code for getting ranges instead. This is the code I used:...

Automate code build and deployment with ansible

Let’s say that we want to keep our system updated with some code which is not distributed as a regular package, but as a code in a repository (which unfortunately, it’s a pretty common situation).

Ansible - dynamically include Jinja templates and tasks
