Setting up keepassxc with yubikey
I use keepassxc to store my passwords. Up until now for my setup I have been using Password + Keyfile as the database credentials, where keyfile has been mostly used as a salt rather than an actual secrets. I store a backup of this keyfile in various online accounts. Because of this I've never been entirely comfortable storing the passwords anywhere online, as it would only require cracking my password. Adding the yubikey secret to the credentials should add an offline factor that will be very difficult to compromise.

ReadHow to add custom alert sounds to Gnome (Ubuntu 18.04)
I'm currently doing my yearly-ish reinstall of my OS. This time doing a fresh install of just basic Ubuntu with gnome, having previously used Ubuntu Mate for the past 1.5-ish years. I like to customize my OS slightly, to give it more personality. For this reinstall I decided to name my OS `mimikyu` after my favourite pokemon. Anyhow, during the process of tweaking I had the idea of making the alert/notification sound the "cry" of mimikyu. My Google-fu wasn't strong enough to able to find a solution online, but I eventually figured it out. Maybe this is of help to someone else in the future.
