I’m not a fan of Google Groups mostly because it’s bloated and slow. But when I joined the Pocket Beagle group I opted for digests of 25 messages by email. I see threads in the digests I can’t find in the page at https://beagleboard.org/discuss#board_forum_embed where I am now. I vaguely remember from years ago thinking Google Groups was just a frontend for usenet. Now I’m not sure what it is. I don’t have a usenet account at the moment so I can’t check. Is this going out over usenet and some people are posting from usenet?
Anyway, since I don’t see a way to respond otherwise to the “Blue screen when sharing Win7 internet connection via usb with pocket beagle” thread: I’ve seen plenty of blue screens, usually something like a bad driver. I made a living keeping Windows running. It’s a little like a kernel panic. Sometimes snapping a picture with a camera helps figure it out later. Usually the last 1/3 or so of the screen is most relevant if I remember right.
Windows connection sharing I didn’t care much for because like tethering from a Android phone the device doing the sharing becomes the DHCP server. If the upstream network goes away so does the local network, suddenly you can’t see local peers. OK in a pinch or if you’re visiting somebody but not very reliable. I went to static IPs and used a program called Wingate, not sure if it’s still around. That was 20 years or so ago.
