I did research on that topic when implementing my project https://adsb.exposed/

The list of all data exchanges is here: https://github.com/ClickHouse/adsb.exposed/?tab=readme-ov-fi...

One of the best is https://airplanes.live/ - which currently aggregates data from nearly 1700 feeders globally; they have a legal agreement preventing sale of this data (to avoid situations like with adsbexchange); they share the data on a selective basis.

One of the largest ones, Opensky Network - is supposed to be open for research purposes but they refused my request straight ahead.

https://adsb.lol/ - is controversial. This database is made available under the Open Database License: http://opendatacommons.org/licenses/odbl/1.0/ plus under CC0, but there is some drama that I don't understand: https://github.com/ClickHouse/adsb.exposed/issues/12#issueco...

Wow! adsb.exposed is an amazing site. The airbus vs. boeing map, showing the dominance in europe and the us, is particularly fascinating.
whataguy commented on Commercial jet collides with Black Hawk helicopter near Reagan airport   mediaite.com/news/breakin... · Posted by u/mzmzmzm

It’s probably really early to ask, but in case anyone here is knowledgeable and has any idea: why didn’t TCAS help avoid the accident? Isn’t it designed for such situations where 2 aircrafts collide? Do military crafts not have it or something?
whataguy · a year ago
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.)

How is this debris tracked – NORAD?
whataguy · a year ago
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.

It's not the waters that's important here. It's the debris passing through the flight path.
whataguy · a year ago
Qantas doesn't own the flight path either?
whataguy commented on ZFS 2.3 released with ZFS raidz expansion   github.com/openzfs/zfs/re... · Posted by u/scrp

I’m interested to know what ‘full integration’ does look like, I use ZFS in Proxmox (Debian-based) and it’s really great and super solid, but I haven’t used ZFS in more vanilla Linux distros. Does Proxmox have things that regular Linux is missing out on, or are there shortcomings and things I just don’t realise about Proxmox?
whataguy · a year ago
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.

I'd suggest you try a color blindness test. The green is very obvious, especially about 40% of the way down the whole image.
whataguy · a year ago
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?
