Some Docker containers ... because Docker is awesome (ignore what Adam says).
VirtualHere is a piece of software that allows you to share USB-devices (Scanner, Printer, Mouse, Keyboard etc.) over the network. This container allows you to run VirtualHere on a Linux-Docker-Host.
FidusWriter is a collaborative online writing tool. This is a docker image that was created following the official installation manual for Ubuntu as closely as possible. It is also referenced from the official documentation of fiduswriter itself.
