Motus is a distrbuted network of ground stations for tracking birds and other species (like bats!) for research - they also use CTT tags for tracking (along with tags from another company called Lotek - https://www.lotek.com)
CarPlay and Android Auto were engineered from the start to be as agnostic to the car's hardware as possible. Your car's stereo is really just a dumb screen (i.e. just a display and input/output interface) with the phone doing most of the rendering + a few other things (i.e. providing some car instrumentation, like fuel remaining, if the manufacturer enables it) - the hardware requirements aren't really strict from a performance standpoint (minus CarPlay Ultra, and even then, that's just a tighter integration).
It depends on the airport! Some smaller airports (like Corona Municipal Airport where the story is based) - are untowered, meaning that there's no central ATC to chat with when taking off/landing - everyone announces what they're doing as they're doing it and there's a traffic pattern/flow that everyone follows to ensure there's no conflicts - it works surprisingly well.
In the US, you can get shockingly very far without having to chat with ATC.
1. This is an official Docker image/container from Ubiquiti themselves - no more relying on LinuxServer.io/jacobalberty, etc...
2. With the "UniFI OS" branding, the door is open to the possibility of being able to run Talk, Protect, Access, etc... on your own hardware in the future.
And don't downplay how much of a role politics can play at making those facts/performance metrics harder/easier to achieve - and some companies are excellent deluding themselves into thinking it's not the case.
I know the intro video is a render - but the folding of the purple sheet looks so... unnatural (to put it lightly) - like the cloth physics do exactly what is convenient for the video and don't reflect reality.
Don't picture them as OTA firmware updates. Picture them as OTA navigation data updates (i.e. maps, charts, waypoints, airport info, etc...) - that's much easier to pull off.
The process right now is pulling out an SD card from your Garmin/Avidyne/BendixKing whatever every 28-days or so (that's how often the FAA updates the navigation database backing these avionics), popping it into your PC, using software/webistes that could be... much better designed (to put it lightly) and then going back again. It's not exactly the hardest thing in the world, but it's not exactly a walk in the park either (especially for less-technically inclined pilots, who just let it lapse, and click out of the big expiration warnings every time they start up their planes).
I can see what was meant with that statement. I do think compression increases Shannon entropy by virtue of it removing repeating patterns of data - Shannon entropy per byte of compressed data increases since it’s now more “random” - all the non-random patterns have been compressed out.
Total information entropy - no. The amount of information conveyed remains the same.
As a pilot, yes, your conclusion is correct - it’s widely known “tribal” knowledge among most American pilots that any reporting on the FAA medical certificate application is ammunition that the FAA can then use to probe for additional information, request further medical tests/notes (which, by the way, likely have to be paid out of pocket), or outright deny the medical certificate, effectively grounding them indefinitely. Appealing that process is long, arduous, and filled with many headaches.
With that said, the application for a medical certificate is a federal form, and willingly lying/omitting information on it is a felony - the FAA has also been known to pull medical records where they can - typically for veterans receiving VA benefits (https://www.washingtonpost.com/politics/2023/08/27/faa-pilot...) - pilots don’t want to get caught in a lie, so many just outright don’t seek treatment for some conditions - particularly mental health ones.
I see this panel ruling as a positive thing because it’s one less thing pilots have to worry about when applying for a medical certificate - knowing they can see a therapist without fearing potential ramifications (because it won’t have to be reported to the FAA in the first place) is a huge step in de-stigmatizing mental health conditions in aviation.
Reading this made me think “huh, where have I seen something like this before?” - an AT&T router was doing something awfully similar back in 2020 - https://news.ycombinator.com/item?id=25335936
Carriers in the US are basically required to route 911 calls, even for devices not on their network - I wonder if that’ll include T-Mobile’s/Starlink announcement (since they’re going to be using existing 5G spectrum, I would presume so) - if I’m out in the wilderness and I experience an emergency, in theory, 911 should just work for me, piggybacking off a Starlink satellite, even if I’m a Verizon or AT&T or whatever subscriber - if that’s the case, I don’t see the need for all of these competing Emergency SOS via Satellite offerings.
I’d imagine the number of highly skilled stunt pilots willing to do a stunt like this drops proportionally in countries with lenient aviation authorities.
> Best might have been to do this stunt outside of FAA jurisdiction.
In order to do this, that would mean not using pilots with an FAA certificate, nor an American-registered aircraft.
Even if they did this over the middle of the ocean, in international waters, if even one of the two things above were used, the FAA still has jurisdiction.
More than likely it'll be a fine for Red Bull/the pilots involved - and at worst a revocation of the pilot certificates for the pilots involved for continuing ahead despite knowing that an exemption wasn't granted.
A backdoor in Curve25519 hasn’t really been a concern, because unlike P-256, the parameters for the curve didn’t come from NIST. Curve25519 is a djb (https://en.wikipedia.org/wiki/Daniel_J._Bernstein) special.
So unless djb was secretly working with the NSA and willing to risk his reputation to backdoor a highly scrutinized elliptic curve, the risk is low.
