Obscufating the location of the starlink unit isn't possible. It inherently requires positioning to function at all.

Starlink uses phased array antennas for beamforming, both on the earth base station and on the satelite station. That means the antenna is very directional by using some complex math and multiple tranceivers feeding an antenna array.

That means the satelite must know where you are within like 10s of km. Otherwise it can't tell where to beam your data.

It's kinda exactly why cell towers can locate you. And why you can't avoid that.

the part that makes the magnets rotate

The magnet doesn't rotate like a CT. But you're right that there is a vessel with supercooled helium.

But that's the first time i've ever heard of this... It's a philips, makes sense.

They're supposed to be designed such that it is impossible. Looks like there was a major recall. Because again, that's something that should never happen.

Look at this article from March 2024: https://robertgarcia.house.gov/media/in-the-news/cnbc-house-democrats-probe-spacex-over-alleged-illegal-export-and-use-starlink

In a statement on Thursday, the congressmen wrote, “Russia’s use of Starlink satellite terminals would be in contravention of U.S. export controls that prohibit Russia from acquiring and utilizing U.S.-produced technology.”

So the equipment has to fall into the wrong hands, through a somehow compromised supply chain. Maybe that could happen without starlink knowing, but they really should have figured that out in march. They should have very easily identified the units that were potentially compromised by auditing shipping logs.

Not only did the supply chain have to be compromised, but also the subscription and payments system... How did they not catch it on the subscription payment side? Now in addition to a compromised supply chain, a financial institution was compromised? At the least, they didn't do their due dilligance in customer verification.

How could russia have set up the equipment without some level of development and testing? Geolocation should have given that development away.

Now, could spaceX do something more about this ? Most likely. But that is resources you need to put on this, which is not profitable.

Yeah good point, that's called "negligence". Not doing due dilligance or taking the necessary steps to avoid breaking the law, because it isn't profitable, isn't a valid legal defense.

It really would have been as simple as geofencing against devices that weren't preauthorized or whitelisted.

MRI machines don't explode and send shrapnel everywhere lmao.

The quench button is used if a person is pinned by a ferrous object, or if there's a large fire in the room and firefighters need to get in the room.

The electrical E-stop button is used if the equipment is on fire, or if there's flooding.

Medical grade or grade-4.0 is less pure than research grade or grade-6. That's 99% vs 99.9999%.

Medical grade might be used for inhalation by patients and traces of other air is perfectly acceptable. MRI cryocoolers need more purity to keep the magnet cold.

"Medical grade" is less pure than what MRIs (research grade).

Medical grade or grade-4.0 is 99% pure and is meant for inhalation. "Research grade" or grade-6 is 99.9999% pure.

Honestly terrifying. Once that info is out there, who knows what could happen.

Will insurance use it to see if you're pre-disposed to something and charge more?

Will a fascist group use it to find groups they think are undesirable? What if there's a genetic component or predisposition to being gay/trans?

Will future terrorists or governments use it to engineer a virus that only affects a group of people? Assasinate an enemy and their entire family?

40% of the winnings is a bargain. The difference in good lawyers is both the time spend on your case, and how much they win.

That 60% wouldn't be gotten without the lawyer.

That's the beauty of intermittent problems!!

You can't prove they aren't there, only that they are, or, that you fail to reproduce.

I hate my job... (lemmy.world)

My job is so fucking unbelievable.

I'll try to sum it up by first telling you about the folks I work with:

First, there is this supermodel wanna-be chick. Yeah, okay, she is pretty hot, but damn is she completely useless. The girl is constantly fixing her hair or putting on makeup. She is extremely self-centered and has never once considered the needs or wants of anyone but herself. She is as dumb as a box of rocks, and I still find it surprising that she has enough brain power to continue to breathe.

The next chick is completely the opposite. She might even be one of the smartest people on the planet. Her career opportunities are endless, and yet she is here with us. She is a zero on a scale of 1 to 10. I'm not sure she even showers, much less shaves her "womanly" parts. I think she might be a lesbian, because every time we drive by the hardware store, she moans like a cat in heat.

But the jewel of the crowd has got to be the fucking stoner. And this guy is more than just your average pothead. In fact, he is baked before he comes to work, during work, and I'm sure after work. He probably hasn't been sober anytime in the last ten years, and he's only 22. He dresses like a beatnik throwback from the 1960's, and to make things worse, he brings his big fucking dog to work. Every fucking day I have to look at this huge Great Dane walk around half-stoned from the second-hand smoke. Hell, sometimes I even think it's trying to talk with its constant bellowing. Also, both of them are constantly hungry, requiring multiple stops to McDonalds and Burger King, every single fucking day.

Anyway, I drive these fucktards around in my van and we solve mysteries and shit.
