Show HN: Find HN threads about the page you're browsing
Love the idea, I have thought about this before and the main issue is training my self to click an extension to check. If an icon flashed when there was a HN submission (ideally only if I didn't come directly from HN since I already know) it would be way more useful.<p>That said we all know the big issue with that is privacy. I don't want an extension sending every url I visit to any service (directly to the API or through some third-party). I've mulled over this issue before and I'm not sure how much space it would take up to store a list of urls that have been submitted to HN (Maybe keep 1 month plus all submissions that got over 100 upvotes or something) and check against that local list.<p>Then, and only then, when you get a match you can call out to the Algolia API to get the HN url (or store that as well depending on size).<p>I have no idea, off the top of my head, what the storage requirements for this look like but I don't think they would be huge. The other issue (which I want to look into the source to see how this handles it) is the stupid social/ads tracking params that are added to URLs. Maybe there is a good list of these that you can remove (from both the current URL and the HN submission) so you can see if it's the same base URL.
