Show HN: Hacker News Title Edit Tracker

Once per 30 seconds. That's in our robots.txt: https://news.ycombinator.com/robots.txt. We've been working for a long time on (edit: what we expect to be) some serious performance improvements that might allow us to relax that limit. For now though, HN's process still runs on a single core and we don't have much performance to spare.

If you need more than that, you should use the Firebase-based API (https://github.com/HackerNews/API). The public dataset is also available as a Google BigQuery table: https://bigquery.cloud.google.com/dataset/bigquery-public-da....

Edit: since this subthread is not really on topic I detached it from https://news.ycombinator.com/item?id=21617478.

>single core

Instead of further optimizing the already light design surely it would be easier to do a gofund me and get a server upgrade? I certainly wouldn't mind chipping in a buck or two if it relaxes limits.

YC is not actually a non profit charity, FYI.

I think the problem is more the software is single threaded. I’m sure YC can afford more than a single core machine.

The software is multi-threaded but it runs on a platform (Racket) which implements that as green threads, meaning it runs them all on a single core.

ah. That makes a lot more sense than hn being short $100. Thanks for modding.

Note that Racket besides threads also has places, which allows programs to use more than one core.

Single core! Raspberry Pi 4? ;)

Oh. Single core.

That's...sad.

I disagree.

I think it's awesome that there's a site this popular out there that _doesn't_ run on resume-fashionable Google/Facebook scale infrastructure that it does not require.

"Yeah boss, we're going to have to pull out memcached and replace it with a kubernates cluster of MongoDB shards. For 'reasons'..."
