Edit: I don't understand the down votes. This happened a while back, nothing has changed except the open source packages made it into a release - which was due anyway?
The HN karma system is the elephant in the room. Everyone knows it affects behavior, but you're supposed to pretend like it isn't there.
I wanted to show that this has been here "for a while".
Outside of the fact that you were the one who posted it earlier, it seems unlikely that you were bothered by the previous posting. I haven't seen you on other reposts on HN saying the same thing. Therefore I am led to conclude that it's not the reposting, but the lack of credit, that upset you.
And if you're really bothered about reposting, on this internet, it's going to be a repetitive experience for you.
Also, if you question your downvotes on HN, you'll get more downvotes and engage in less conversations from which you can learn.
