A sensible NixOS Xfce Configuration

NixOS provides good support for the Xfce desktop environment out-of-the-box, but the defaults are minimal. The files in this Gist provide a more complete experience, including a suite of basic software and plugins as well as an optional home-manager configuration for theming.

The key additions to the default Xfce provided by NixOS are:

Complete bluetooth / audio support with panel indicators and apps
LightDM with theme
Extra Xfce apps for calendaring, disk partitioning, etc.
Various quality-of-life improving non-essentials

Proxmox PVE Host Config Backup Script

This script can be used to backup essential configuration files from the Proxmox Virtual Enivronment (PVE) host.

The script will create backups using tar with specified backup prefix and date and time stamp in the file name. Script will also delete backups that are older then number of days specified.

Create backup script file

To create backup script that will be executed every day we can create backup script in /etc/cron.daily/ folder. We need to make it writeable by root (creator) only, but readable and executable by everyone:

touch /etc/cron.daily/pvehost-backup

Setting up email with SMTP on Ubuntu/Debian Servers

I used to sift trough my shell history and bookmarks every time I set up a new testing server in order to be able to send mails. So this should help...

Be aware don't use ssmtp anymore. It's unmaintained and has been removed from Debian and Ubuntu will most definitely follow suit.
