Somewhat related, nature photographer/youtuber Danni Connor had her recording of a red squirrel used in the movie Dune (Part 1) for the sound of the desert mouse (muad'dib). Her interviewing with (Oscar-winning) sound designer Mark Mangini on it:
> If bad actors can create valid tls certs they can solve the dnssec problem.
I think you have it backwards: by not running DNSSEC it can mean bad actors (at least a certain level) can MITM the DNS queries that are used to validate ACME certs.
It is now mandated that public CAs have to verify DNSSEC before issuing a cert:
If you mean MITM between DNS Server and CA (e.g. letsencrypt), thats on a level of BGP hacking (means for me government involved) and means they can just use a CA (e.g. Fina CA 2025 with cloudflare).
I think the risk didn't change much (except for big corp/bank).
> I don't understand why new houses don't just have one high quality AC/DC converter so you can just use LED lighting without every bulb needing its own AC/DC converter.
IEEE 802.3bt can deliver up to 71W at the destination: just pull Cat 5/6 everywhere.
In the commercial/industrial space this may be worth it: how long do these bulbs last? how much (per hour (equivalent)) do you pay your facilities folks? how much time does it take for employees or tenants to report an outage and for your folks to get a ladder (or scissor lift) to change the bulb?
I think the most generous interpretation of using 'all' ADS-B data (including things on the ground) would be to have VR and have boxes for all objects, à la the F-35 helmet:
The entire point is that there's no need for someone driving a ground vehicle to see all the ADS-B data. They only need to know if and when a plane is projected to cross the direction in which they're facing. It might also be useful to know the projected speed as well as how far in front of your vehicle it will pass (but you can presumably figure the latter out on your own because, y'know, the runway).
There are three categories of runway incursion types: operator/ATC error, pilot error, pedestrian/vehicle. Even if someone 'knows' that they need to "hold short runway 12", they can still have a brain fart and go through the hold short line.
Unless you want to argue that all vehicles taxiing have to operate (SAE Level 4) autonomously?
The issue is that the final approach and landing (and taxiing?) environments are probably too dynamic for that: in this particular situation one of the vehicles was responding to an emergency (fire).
In addition to huge planes, there is baggage transportation, passenger buses (to mid-field terminals), fuel pumpers, emergency vehicles, snow plows, deicers, and general maintenance vehicles (clear debris off runways).
Given there are ~45,000 flights per days in the US (and so aircraft and vehicles would move hither and fro around an airport for each flight), 1700 feels like a small number.
Exactly - it's a small number and should be investigated, because if we reduce the number of all incursions, we reduce the number of collisions (and fatalities).
They are classified as operation/ATC error, pilot error, and vehicle/pedestrian error.
Human can misspeak or mishear instructions, but if they were communicated and understood correctly (a read back was correct), but the pilot had a 'brain fart' and went forward instead of stopping, how do we eliminate brain farts?
NOTE-
Previous reviews of air traffic events, involving LUAW instructions, revealed that a significant number of pilots read back LUAW instructions correctly and departed without a takeoff clearance. LUAW instructions are not to be confused with a departure clearance; the outcome could be catastrophic, especially during intersecting runway operations.
The older term was "hold short runway X" and that was too close to "hold runway X" - the first meant do NOT enter the runway, the second meant enter and line up but do NOT takeoff.
But in the highly dynamic environment of final approach, landing, and taxiing, I doubt it would be practical. Unless we want to try autonomous 'driving' on taxiways and runways?
