A Byte of Coding Issue 385

Hey,

Some of you might’ve noticed that there was no issue yesterday. My apologies, I ran a software update in the morning (as I was writing the newsletter) that ended up breaking the display manager on my machine. I then had to spend the whole day fixing the issue. Spoiler, it ended up being a corrupted xorg server package. My laptop froze and had to be shutdown mid system update, which is what caused the issue. Fun stuff.

Anyway, here’s the issue.
