       | Had the same idea yesterday (see my failed attempts at
       | https://news.ycombinator.com/submitted?id=capableweb, unable to
       | delete them after a few tries) but both the website + API were
       | too slow to update for me to be able to guess the right idea.
       | When the website showed that one ID existed, there were already
       | multiple ones created afterwards...
       | 
       | Any clues to how you did this?

         | I was basically just checking the latest ids (you can estimate
         | it based on the /newest submissions and then increase until you
         | hit the "No such item."-response.
         | 
         | In my case I guess I was lucky that there was not much traffic.
         | However I was on mobile when I started observing the ids but
         | finally switched to PC as I felt on PC I can react much
         | quicker.

         | It's a PoC for HN related to this submission:
         | https://news.ycombinator.com/item?id=33127285
         | 
         | Basically I guessed the id of the submission (HN has a global
         | counter for each comment or submission).

           | That's... kinda of letdown. Was expecting a more intrigued
           | approach but apparently HN is slow enough for guessing to
           | work.

             | I actually was first thinking about writing a small script
             | to check if an ID is in use and then auto create a
             | submission.. however I first checked how often the ids
             | actually change.. and in the moment I checked it was about
             | one new comment/submission every 30 seconds.
             | 
             | I guess an timezone advantage .. when there is more traffic
             | I guess the automation would win.

             | you can reference a YouTube video id in the video itself.
             | that's much harder to do.

               | 
               | It works because there are two requests associated with
               | creating a YouTube video. First, the metadata is sent
               | (file size, video title, etc.) and it returns a video ID.
               | Then the actual video content is sent. I cancelled the
               | upload request and replaced the video with a new one I
               | rendered quickly.
