Do you have any source for this? I'd love to know more about how they re rank items incrementally.
Do they actually update every single row in the database every 5 minutes? It seems too slow.

- dangrossman 11y agoHN doesn't use a database. There are no rows. Just one process on one server with everything in memory. Data is lazy loaded from flat files on-demand.
