Setup DNS-over-TLS with systemd on Ubuntu 18.04

This gist will explain how to setup DNS-over-TLS on your local computer.

Verify systemd version

To make it work, you need at least systemd version 237 or 242.

I'll use the version 242 in this gist.

Painless ESLint/Standard integration

Our goal, here, is threefold:

• use Vim's built-in features to their fullest,
• be a good project citizen even if we don't use $EDITOR_DU_JOUR,
• have a minimal but beneficial impact on the infrastructure of the project we work on.

Expose a simple interface for linting at the project level
