I share the sentiment. I want a new car, but only if I can guarantee all telemetry is hard disabled. But I don’t have the kind of money to buy a new car and risk bricking it. Luckily I’m pretty handy, so I’ll have to keep my 2014< cars forcefully running as long as I can.
I have non concerns about having a built in button to phone emergency services. I don’t even mind if it auto rings in a crash. I’m even happy to provide position to the emergency service in the event of dialing them.
Manufacturers use this capacity as an excuse to push more adtech penny and dime data abuse, knowing half the world will blame the government.
From a cellphone’s perspective a crash = extreme acceleration with different vectors vs a dropped phone, they can also listen for broken glass etc. So even with GPS off that’s detectable.
Generally I read your comment that a dropped phone only hits the floor once, therefore there is only one vector and the car always overturns/flips/turns and therefore there are multiple vectors measurable in the car?
I am not convinced yet, it might be possible without GPS, at least to some degree of error (false positives and false negatives).
The info in the link requires GPS to be switched on.
hmm
Disabling the antennas is the only way to be sure. There will typically be a coax connection that you can cap with a terminator. GPS can be merged with other radios you might not want to lose but suitable splitters are available.
GPS uses a different frequency and a very weak signal. The antenna is typically separate from the others but it's very small <5 mm¹. It can be on the same board with other antennas with 3…4 cm separation between them. Also, we tested a GSM tracker and it still worked with a mismatched antenna. This was in Eastern Europe where cell tower power is quite strong. You have to completely remove the antenna and terminate its connection to be 100% sure. If you have coax cables with external antennas, you're lucky. The worst case scenario is when they're embedded in the infotainment system with amtennas and everything. This is also a cost cutting measure, so it's very likely to be used. The infotainment system is usually ideally placed under the windshield for undisturbed signal reception. But there is still hope to completely cover its back side and edges with aluminium foil tape.
I thought most would use their “shark fin” on the roof for everything (if there is one but there usually is). Terminating on the other end somewhere with a color coded FAKRA connector.
That's quite far away for the weak GPS signal over RF cable, but they still do it. Or maybe the GPS unit and LTE modem are also in the shark fin or nearby and they use a serial, CAN FD/XL or single pair ethernet connection to it? Another choice is in the center of the dashboard under the winshield or under the mirror.
Ford has GPS with FM on the same cable. They have splitters for this arrangement. This is why they transitioned to stubby antennas for better GPS and good enough FM.
You can do this already. Leave the map up, but silence all direction corrections. Then try to make your own way. If you already have the time to chill, you can take a little more time to think ahead about the route you’ll try. Make a wrong turn or exit and the map will still point you in the right direction.
> niobium arsenide may not be a practical replacement for copper – arsenide is toxic, after all
So may it replace, or may it not replace? Title contradicts the closing statement.
Even still, awesome to see more alternatives advancement’s and improvements to synthesis processes. Faster testing is the real breakthrough in this piece.
Niobium arsenide cannot replace copper in wires or cables, for two reasons, it is many times more expensive and it is fragile, so it cannot bend.
Moreover, at normal sizes it is not a better conductor than copper, so it would have no advantage anyway.
According to this research, it could replace copper for one or for a few conducting layers inside an integrated circuit, those with the finest pitch, while the thick conducting layers used for carrying great currents would remain of copper.
The toxicity of arsenic is irrelevant. Only extremely small quantities are necessary and they are sealed inside the integrated circuit. Almost all integrated circuits already contain arsenic, as it is the best N-doping element for silicon (because the size of the arsenic atoms is better matched with the size of silicon atoms than the sizes of phosphorus or antimony atoms).
They could say anything and the visitors would have to believe it. A canyon tour guide tells me a story about why a rock formation is named the way it is. I have no clue if it’s true. But I enjoy it still.
What if you could group multiple of them. Long queries run on the group that’s commonly doing those. Shorter queries que faster because they’ll execute faster.
Will kids raised on it not know anything different? Seems a path to reduce computer literacy. Then again, being blocked from doing something I wanted is what lead me to find ways around said block. But I already had unrestricted access to the system to bend it to my will. Seems like these kinds of systems won’t allow for the user to learn how to works at all. It’s a mystery box.
Because the early adopters are the nerds that will discover how to exploit it, the popularity will make others want to use it, and the normies will take the easy route it gives them since self hosting is hard for them.
I essentially do a 1 click deployment for my personal site with Cloudflare.
I don't want to deal with the cloud infra for my personal site.
I could, I've done it in corporate, I've done it for my startup 2 years ago.
But I'm rusty, I don't know what the latest people are using for configuration, etc.
Because there is 1 click with CF or Vercel and I don't have to think about it—I don't.
If they increase their price it likely wouldn't be enough friction for me dust off the rust.
I think this is the relation.
I'm not locked in, it's just HTML pages, but I am through my own habit energy, tech changing, and what I want to put effort into, which is not infra and serving my site.
The best way it works is if you have trust with just a few people, and your network availability grows as people connect to more people.
Could even start as a virtual private network of sorts.
I have trust with my friend A. They add. Friend B, who I can only see because I know A. If we have a need to talk to each other, then we can proxy through A.
Don’t know exactly how this scales… it becomes a tor network of sorts. But you actually know the peers chaining your requests together to some degree. You get a bad request, you respond that you don’t want communication with that peer anymore. The message hops back through the chain and each peer decides to drop the route for you.
Each peer has their own rate limits, preventing certain floods from happening. One bad actor floods out from many locations, eventually it all connects back toy eh bad actor. Don’t need a vpn on this network, as you’re already tunneling around through others.
How to handle bot nets would be interesting. Basically as nodes detect bad traffic eventually the word gets around to put those nodes into a high risk status. Owners of those nodes would be able to see they’re being restricted. It’s up to them to stop the bad traffic from coming from their own devices.
