I have always liked links. When I used to make Cocoa Apps for enterprise customers I liked adding things like Webkit to load cool HTML links and work with custom URLs. There is something about making something pop-up on screen from an otherwise static application that seems fancy to me. Sometimes I need to setup an environment (often linux) that needs a user to interact with a docker container. While docker exec is very similar to ssh, it lacks a

However to create content in gitlab out of the box , or run something like git push --mirror you have to disable the branch protection.

For instance if you have some yum based fact that dynamically generates many more facts and wanted to confine it only to RedHat, you can simply do the following:
