If you're using Chrome, this extension works great to let you know about pages being on HN: https://chrome.google.com/webstore/detail/njdndkhkelkeepcnmookckfhl

  I've just tried this one and it's great! It's simple, unobtrusive and smart: a logo in the address bar indicates that the post is already on HN. If you click it you're taken to the comments page. Neat!

  I'm pleased to see that this extension sends only the hashed URL to its server, so you're not giving away your full browsing history in real time: var url_hash = hex_md5(tab.url); xhr.open("GET", "http://hnd.mfairley.com/" + url_hash, true); https://github.com/michaelfairley/hnd-client/blob/master/background.html https://github.com/michaelfairley/hnd-client/blob/master/bac...

    Awesome for security. In order for this to work, the server-side has to keep a record of every single URL posted to HN, to be able to do a lookup of the hash. It's crawling the "/newest" page [1] once a minute [2]. Not sure how he handles situations where the worker goes down (do those posts just not get indexed?).
