A similar discussion from 2021 that didn't track a lot of attention: https://news.ycombinator.com/item?id=29165586

And the only answer from eesmith cites a very old implementation, I'm wondering what's being used nowadays in the HN code base

I think hackernews was originally built with a Lisp language right?!

If so, probably started with a database that you would commonly pair with a Lisp language

Arc.

And the filesystem.

Every discussion I've seen mentions filesystem-based storage rather than any database. Haven't seen any evidence to the contrary.

Would that handle the demand? This is a very busy website.

They have a job listing looking for engineers. I have no idea if this role would work on HN or if the tech stack is relevant to HN.

It lists the tech stack as Rails, React, Postgres.

HN is not written in React or Rails. It is written in a LISP dialect called Arc.

That’s a YC job post not HN.
