No, it’s not off-topic. I’m not claiming to have reverse-engineered that stuff (I have successfully reverse-engineered internal Apple tech in the past, and it hasn’t ended well. I’ve been writing Apple software, sometimes, at a fairly low level, for quite a while). I suspect there may be other reasons for the downvotes. It isn’t really something I’m losing much sleep over.

It’s just a fairly typical type of HN comment. I literally, like, yesterday, got it going, and it was a less-than-linear process. My own experience, in hacking the system, has taught me to try to stay inside the lines –something that is increasingly difficult, these days.

This article (which is excellent, and quite worthy of HN) made me think of it. Also, even doing what I did, has its challenges. I didn’t want to distract from the OP, by going into any detail. Maybe, one day, I’ll write it up (I’m fairly good at that kind of thing), but that is something for another day.
