XScreenSaver: Simplified Guide

What Is XScreenSaver?

XScreenSaver is a collection of screen savers for X Window System. Each "module" is a standalone program that renders graphics to a window created by the XScreenSaver daemon.

Basic Approach

Any program can be a screensaver if it can draw on a window it didn't create
You must use C (not C++) because other languages typically can't draw to external windows
XScreenSaver provides utility functions to make development easier

	Import-Module posh-git
	Import-Module PSFzf

	# Set initial directory

PostgreSQL is Enough

Background and Cron Jobs

	# simple bind mount - directly maps host directory to container
	# pro: simple, direct
	# con: less docker-native management
	volumes:
	- /opt/medusa/postgres:/var/lib/postgresql/data

	# named volume with bind properties - docker managed but host-accessible
	# pro: docker volume features (named reference, metadata, drivers)
	# con: more verbose, possibly overengineered for simple needs
	volumes:
