" acknowledging that doing so changes the risk profile of aviation to some extent" Isn't that what the NOTAM is?


Clearly the NOTAMs aren't doing the job, as this isn't the only instance of issues. It's just the only instance of a crash with fatalities.


So they should turn off the GPS interference whenever they're asked to do so by ATC. Which they did in this case. The timeline is something like , NOTAM issued, flight takes off, flight has issues, ATC asked the military to turn off the interference, the military complies, the flight says they're good now and the interference can continue, ATC informes the military that they can continue, they do, and then the flight crashes. I don't see how the military carries any fault here.


That's like saying "what, it was published in the paper of record in your local area!"

NOTAMs have so many issues it's not even funny. There's so many of them and 9/10 of them are irrelevant for one.


NOTAM is itself a broken system responsible for many mishaps.


I'm not especially anti-LLM but emergency messages seems like a terrible use case. If you're typing out a detailed emergency message then I would think you would need all of your details to be sent or you could simply type a shorter message.


Julian date is sometimes used to synchronize timing for encrypted radio systems. My understanding is that early radio systems adapted it because it was used by astronomers. Astronomers used it because it didn't skip any days which would cause issues tracking long term astronomical cycles.


Julian date works exactly like Unix epoch, but instead of starting in junary 1 1970 it starts something like 2500 years ago.

Super easy for astronomy as you don't need to handle timezones and other junk


> Astronomers used it

And still use, in fact!


I deal with those radio systems occasionally and I've always wanted to find or modify a digital watch to display the Julian date. It feels like that would be such a simple firmware change to something like a g-shock.


Check out the Sensor Watch project[1]! It's "An ARM Cortex M0+ board swap for the classic Casio F-91W wristwatch" that allows you to write custom firmware.

Thank you! That's exactly what I'm looking for.


The big annoyance with Julian days/dates is that they start at noon, not midnight.


They all have to be manually cleared for release


"where technology is used to distract, extract, surveil, and kill"

The first general purpose, programmable computer was designed in 1945 to calculate artillery firing tables for the US Army and was immediately used to help design nuclear weapons. Computers and all technology has always been, and will always be, used as a weapon (either directly or indirectly).


See below that:

'Don't believe self-serving lies about technologies being "inevitable" or "here to stay". You don't have to just go along with the dominant narrative. You can make deliberate choices and help others to do the same.'


What technology has been invented and abandoned due to moral reasons?


A modern John Deere tractor with a robust right-to-repair would still be a pain to do maintenance on. A big part of the reason people want old tractors is because they don't have these additional computer controlled systems which break and require time and effort to fix.

Gotcha, I couldn't tell if it was Grandpa or one of the bros who locked her in the closet


There have always been lame people like this and for all of human history we have continued to explore and expand. I think at this point those people can safely be ignored.


Considering sociology and similar field's complete lack of correlation between data and conclusion, I don't believe they should be considered "science". They're more similar to astrology and phrenology.


The term you are probably searching for is "political manipulation." They should be considered political manipulation.


I don't know about Bentley but Porsche makes hybrid electric drivetrains which would include lithium electric batteries
