Liberal, Accurate Regex Pattern for Matching Web URLs
The regex patterns in this gist are intended only to match web URLs -- http,
https, and naked domains like "example.com". For a pattern that attempts to
match all URLs, regardless of protocol, see: https://gist.github.com/gruber/249502

GitHub - Delete commits history with git commands

First Method

Deleting the .git folder may cause problems in our git repository. If we want to delete all of our commits history, but keep the code in its current state, try this:

# Check out to a temporary branch:
git checkout --orphan TEMP_BRANCH

# Add all the files:
git add -A

Automatically generate ansible tags of the same name for each role in a playbook
"""
This module implements an Ansible plugin that is triggered at the start of a playbook.
The plugin dynamically generates a tag for each role. Each tag has the same name as its role.
The advantage of this is that it saves you some boilerplate, because you don't have to wrap
all tasks of a role in an additional block and assign a tag to that.
Additionally, it works automatically when you add new roles to your playbook.
Usage is exactly the same as without this plugin:
