      I think the best part is how short and elegant it is.

      I assume a lot of people won’t realize you can bookmark that URL since it looks so weird. Also, once you’re bookmarking, you can cheat and put more logic into the page. I made a slightly improved one with a dark background and larger font (hard to post the link on HN, so on a separate page):

      Turn each one of these to a browser bookmarklet using a template like

      with

      Hey Simon,

      Hmmm, you're right about the IE issues (http://mrcoles.com/blog/cookies-max-age-vs-expires/). I haven't looked into how possible/hard expires would be in nginx config, but you could probably hack it in with http://wiki.nginx.org/HttpUserIdModule

      But how are you going to replace the OG? https://mrcoles.com/dragondrop/

      (Ironically doesn’t work on mobile)

    • neogodlessJun 2019

      Yes, the article actually links to a demo of this technique!
