Ask HN: Any group to learn xv6 together?

I am going through the xv6 course from MIT[1]. On my own.

I wonder if there any group/chat/place that discusses this? There was a thread 8 months ago, but I mised that train. I want to find community where I can discuss this thing or to find some motivation to go trough the hardest parts of xv6 labs.
