I know I am being pedantic, but it is a bit weird to editorialize "How I Implemented /dev/printerfact in Rust" to "I Implemented...", make the author come off a little more boastful than they intended to.
Also printerfact was implemented by a high person with sed and a list of cat facts. While excellent, it's not an incredible achievement we need to defend the integrity of.
