Wow! adsb.exposed is an amazing site. The airbus vs. boeing map, showing the dominance in europe and the us, is particularly fascinating.

It’s likely both the helicopter and the jet received a TCAS warning. In dense airspaces, those alerts tend to trigger frequently, so there’s a strong chance they may have dismissed it. The CRJ crew might have been aware of the Blackhawk’s presence, but if the other crew had visual contact with the approaching traffic (the CRJ), they might not have felt the need to take further action.

They also changed the design of issue comments, but seemingly reverted it back to the old design in production? (If you check the first video on the blog you can see e.g. the profile picture inside of the comment, while the old and current version has it on the outside.)

No, it's tracked by the Space Surveillance Network (SSN) operated by the U. S. Air Force. They have satellite and ground sensors around the world.

The difference is that the ZFS kernel module is included by default with Proxmox, whereas with e.g. Debian, you would need to install it manually.

No, I see the green, but I don't see any shaded green. Though this has probably to do that ISBNs are distributed in blocks and every pixel is either red or green?

> Each pixel represents 2,500 ISBNs. If we have a file for an ISBN, we make that pixel more green.

What do you mean by "more green"? I don't see any shaded green.

And I presume the black pixels are unregistered ISBNs?
