The set lines
set -euxo pipefail is short for:set -e
set -u
This should work on other Fedora-based distributions and for other packages, but I have not done extensive testing
Using up-to-date versions of software on RHEL is a pain. I understand the eneterprise benefits, but configuring a development environment can be confusing, with most people using a combination of symlinks, adding folders to PATH, and enabling an scl_source
While this is still generally acceptable, there exists an alternative method (sorry).
The alternatives essentially creates a symlink, but it actually is a symbolic link to the alternatives directory, which in turn is a symbolic link to the actual program.
This allows for better package management and confines all sysadmin changes to the /etc directory, all while making switching back easier. It feels to me a lot like virtualenv in python

Convert .mov/.MP4 to .gif
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.
Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).
docker run -it --rm --privileged --pid=host justincormack/nsenter1
