Ask HN: How to check if URL is posted to HN (without actually posting it)
Is it possible to check if a URL has been posted to HN without actually posting it?
- jayliew 16y agoOne way, although inelegant, would be to post a URL and see if I can delete it right away. If I can, that means it hasn't been posted prior to me posting. I'll have to detect the "0 minutes ago" and the delete link If I cannot delete, that means it already exists
- callmeed 16y agoThere's a Chrome extension that adds a tab with an URL's HN comments on the side. It will show up for any URL on HN (I think).
- jayliew 16y agoThis one? http://github.com/adamalbrecht/hacker-news-for-chrome http://github.com/adamalbrecht/hacker-news-for-chrome Just tried it, there doesn't appear to be a way to check if a URL is already posted or not
- FrancescoRizzi 16y agoslightly off-topic, I guess but... I think that checking if the same 'topic' (page title, main keywords, etc) has been posted may be more important. After all, even if nobody posted yet the URL I'm looking at... but if that URL is a brief blog post linking to another blog that passes through to the actual story... and if that story has been posted to HN... then I might as well add the URL I was looking at in a comment. No?
- jayliew 16y agogood point, but that's gonna be hard for recurring popular topics. It's gonna be difficult to tell the difference between "iPhone kills Android" vs "Android kills iPhone"
