Switching Between Networks With wpa_supplicant
Easy switching between networks when you don't have a desktop environment
Background
My setup manages its Wi-Fi connection with wpa_supplicant but doesn't have a desktop environment so it's kind of annoying when I want to switch VLANs to manage my IoT devices.
The two networks I'm switching between are defined in /etc/wpa_supplicant/wpa_supplicant-wlp2s0.conf and their priority set by the priority variable. To make switching easier, I've made a script to flip the priorities and restart the wpa_supplicant systemd service.
Solution
#!/usr/bin/python3
import subprocess
with open('/etc/wpa_supplicant/wpa_supplicant-wlp2s0.conf', 'r') as …Setting Up The Chia Network On A Synology NAS
Does money grow on hard drives?
This is probably dumb but I'm doing it anyway

Setup
I'll be using the Virtual Machine Manager of …
Installing & Configuring Mariadb for Arch Linux
A guide to installing and configuring Mariadb on Arch Linux
Background
This website runs on a Digital Ocean Ubuntu VPS, and uses MySQL as it's backend database. I want to use my Arch Linux laptop to develop and test new code for the website so I need a database to use for the test environment. I could use Docker which would probably be the better option if I wanted to emulate the production database on this VPS as closely as possible but I've never …
Resizing Partitions
Reallocating disk space from home to root partition
The Background
On my recent Arch install, I decided to create separate partitions for my root and home directories. Unfortunately, I'm a dummy and only allocated 20 GB for the root partition. As it turns out, that's not enough for a proper workstation setup so now I have to fix my mistake.
The Fix
My particular install involves two usb drives, one with the Arch boot partition and the other with a cryptographic key to …
Setting up a Video Background Login Screen
Documenting my setup for creating a login screen with a video background.
Background
Recently I was inspired to switch over to Arch Linux after seeing this post by u/EmpressNoodle over at /r/unixporn.
During my Arch install, I decided to use SDDM as my display manager. One of it's features is the ability to use videos as the background of the login screen so I figured I'd give that a go.
Configuration
First, I had to decide on the base theme that I wanted to customize. My …
