I feel like I'm missing some context here. Who is DHH and why is his desktop so desirable?

The main page says it's "opinionated" and has two thumbnails of desktops that are mostly just a background image.

DHH is the creator of Ruby On Rails. He is also a rich opinionated high energy asshole (so your average Apple fanboi). Those thumbnails are videos that explain and show the workflow of his desktop.

		Seems a bit reductive when the post is literally him pushing Arch Linux and he's also been hyping Framework and talking about his Apple departure for quite a while now. But also for GP, there's literally an "About DHH" section at the bottom of the pretty short post you're commenting on.
