Show HN has a long history of people just posting random shit they’ve built that they think is cool.

Some of it is in pursuit of productization feedback. Some of it isn’t.

The general audience here is (or at least, used to be) tech enthusiasts, and you can usually assume that crowd will enjoy cool shit in tech.

Personally I’ve had to occasionally hand write x86 assembly for work on a handful of occasions to ensure certain runtime guarantees were met that the programming language i was using couldn’t provide directly. I’ve used it a ton in hobby projects because it’s just kinda cool, and i want to have a better understanding of that world.
