Your timing is terrible. Best time to post something on HN is 8:30 eastern time, that way you get the best chance of being noticed. Evening is almost certainly going to miss the majority of the visitors to the site and by morning your post will be gone.
What didn't help is that you posted it as 'self post', so one without a link (those are penalized).
Better to wait until 8:30 tomorrow morning, post it as a linked article and put your explanatory text in the first comment.
Good luck!
