Makes my brain tingle in weird ways, reading different snippets of this article. Where it talks about "A:" being the floppy drive, suddenly I'm an early 90s kid again, learning the basics of my first home computer (an Olivetti 286 with MS-DOS and a green screen). Where it talks about proxying SSL with Caddy, fast-forward to being a 2010s web dev.

And I like the screenshot showing "Bad command or file name". I saw that message plenty of times, although now it seems like a lifetime ago!
