Setting up postgres with PostGIS for geodjango on Arch.
sudo pacman -S postgresql
Setting up data directory within my /home partition:
mkdir -p /home/myuser/postgresdb_data/data
sudo chown -R postgres:postgres /home/myuser/postgresdb_data
sudo -iu postgres
initdb -D /home/myuser/postgresdb_data/data
Edit the systemd service file:
sudo systemctl edit postgresql
Add the following:
Edit /home/myuser/postgresdb_data/data/postgresql.conf to listen exclusively through UNIX sockets and we'll also set password encryption to scram-sha-256:
listen_addresses = ''
password_encryption = scram-sha-256
Edit /home/myuser/postgresdb_data/data/pg_hba.conf to …

Easy switching between networks when you don't have a desktop environment
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.
with open('/etc/wpa_supplicant/wpa_supplicant-wlp2s0.conf', 'r') as …
Does money grow on hard drives?
This is probably dumb but I'm doing it anyway
Chia is going to be the next big crypto craze. Or at least that's what their website tries to make the case for.

I'll be using the Virtual Machine Manager of …
A guide to installing and configuring Mariadb on Arch Linux

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 …
Reallocating disk space from home to root partition
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.
My particular install involves two usb drives, one with the Arch boot partition and the other with a cryptographic key to …
Documenting my setup for creating a login screen with a video background.
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.
First, I had to decide on the base theme that I wanted to customize. My …
