Source: http://docs.ansible.com/ansible/latest/playbooks_variables.html#variable-precedence-where-should-i-put-a-variable

From least to most important

Getting Started

The following command will install the latest version of REX-Ray to /usr/bin/rexray on Linux systems:

$ sudo apt install s3fs
$ curl -sSL https://dl.bintray.com/emccode/rexray/install | sh

Depending on the Linux distribution REX-Ray will be registered as either a SystemD or SystemV service.

Configure

REX-Ray requires a configuration file for storing details used to communicate with storage providers. This can include authentication credentials and driver specific configuration options. After REX-Ray has been installed, copy and paste the contents below to a new file on the host at /etc/rexray/config.yml to configure s3fs storage driver.

Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

Golang installation guide

Since Golang version 1.11 this process is finally (almost) as easy as it should (!!). You can see full docs here. For older guides see here.

These are my notes, not a generic solution. They are not meant to work anywhere outside my machines. Update version numbers to whatever are the current ones while you do this.

Installing everything needed the first time

Install asdf and its golang plugin, then install golang
