Hmm. Feeling very good about dumping iPhone to simple flip. My last iPhone was old SE with home button and touch ID. Somehow I managed to remove smartphone habits of my life. It is a bliss. Highly recommend. It is a stellar investment in ones future, psychologically, technically and in general.

If you don't mind my asking, what model flip phone did you settle on? I had one I really liked, but carriers are dropping support for the 3G network it uses, and it seems like all the 4G-compatible options either run Android or have issues with basic functionality like receiving calls. (Or both!)

Phones are insecure by design, in my country log-file metadata of calls and sms is kept by operators (and it is not optional), people don't read the small font agreement from long time ago.

So my approach is to use the device with this in mind. Some form of data will be transmitted and sold by operators or third party backdoor from manufacturers. The goal is to minimize data exhaust so I bought this

As I sad before, the problem is not only in devices and dark patterns designs towards data gathering. The problem is that we have learned to adapt to the "new tech" and are excited to try "new things" without any form of critical thinking and with automatic trust.

I was a part of this "tech fetishism" crowd, I wanted "the best" and "most advanced" not only to socially validate myself but to be "on the verge of tech".

This was in 2015. Now I have a different mindset. I know what tech companies and governments want. I know the people who live comfortably knowing that they create a spyware and UX dead traps, and when I ask the answer is : Shrug and take the money.

So I decided to move radically forward.

Imagine that we are living in 2030. There is no privacy, cars are scanning everything with Lidar, IR and thousand cameras, listening and collecting, the street-lamps are with integrated CCTVs, you get the picture.

So what will give some form of real advantage for the individual in this panopticon? Low data exhaust. The little you give to surveillance system, the more power you will have when making deals with businesses and government organizations.

Working with Internet now, requires VPN, Firewall, Pihole, browser extensions for privacy, decentralized services, etc. Imagine in 2030. There will be no way to use it anonymously and legally. Nobody will stop this. This is the new WEF approved business future. For the children, for the environment, for safety and "peace of mind".

There is one exception and you can use your power now. The power of consumer choice.

My is to invest in my idea of tech future by one factor: Consumer control. If I have to abandon the Internet so be it. If the only connections to Data Towers are the mandatory ones, I will be satisfied. Listening to my own collection of music (CD rips and Vinyl), reading physical books, browsing my vast data collection offline.

And I find this logical and absolutely normal. There is no tin-foil hat reaction. There is data and everyone is free to analyze and create his own version of "reality".

Without disagreeing with anything you've said there, even if you /think/ you have nothing to hide now and happen to be correct in practice, it's a terrible assumption to think that you can count on that being true forever. Imagine you witness a murder in a restaurant, cold blooded and it's dirty cops working for a three letter institution that did it. You want to give evidence like a law abiding, upstanding citizen w…

Fully agree. This idea that "individuals arent spied on in America" is absurdly naive and ignorant of seemingly common knowledge of past events. Furthermore it's kind of implicitly supremacist - "only those foreigners do that sort of thing". Police regularly bust young Chinese for marijuana possession by reading their chat messages. And we are just as human and no more special than the Chinese. A friend of mine was t…

Especially with the still recent insurrection/coupe attempt by a fascist leaning politician on American soil. It's actually pretty scary. Democracy is not as assured as some people seem to think and shouldn't be taken for granted.

And how many people drive more than 300km per day AND don't have the time to wait 50 minutes, but only got 5? The replaceable car batteries is technically possible (heck, everything is possible with engineering), but totally useless.

So it's possible and you reply to a person telling you about a legitimate usecase but you continue to go on about how it is totally useless?

How many such stations will be built and how many different shapes, sizes, battery chemistry, and capacity batteries will each station have to have in stock?

It sounds like it isn't even possible except in the trivial sense that if one has a fully charged battery of exactly the right type on hand, then it can be swapped in five minutes. Sounds like each station would either have to have a large store of batteries or it would have to only serve one model of car. The first is a large capital cost, the second generates very little revenue.

To compete with, say Tesla, Nio would have to build hundreds of battery swap stations in Europe. Tesla has 601 sites in 27 countries. When I drive from Norway to the UK I am rarely more than 50 km from a supercharger.

AOP has been a thing since iPhone 6s, so they're not particularly rushed in documenting it.

I can't go too into details, but now that the AOP is doing cryptographical operations and key escrow, the internal bus is likely to show up in future documents. Maybe not the AOP but certainly the mechanisms it uses to interact with the find my network. It may also be a separate find my network whitepaper.

Is the AOP still involved in Find My, even on a 6s/6s Plus?

Edit: I read the TFA, which says 11 and up.

The chances of you being directly spied on are low. The chances of someone being spied on who could influence the world around you is much higher. So a journalist could be spied on right before they break a big story, potentially leading to a cover up. That’s the problem with stuff like this. Even if you have “nothing to hide” you might rely on someone who legitimately does.

> "I have nothing to hide" is is gradeschool silliness to be treated with contempt every time it comes up. It needs to be ridiculed as anyone suggesting it is an idiot or just totally and knowingly dishonest.

That might be an aspirational sentiment, but given most competent adults are in the "I have nothing to hide" category, I don't think it's true at all. I don't think these people are idiots, or dishonest, just ignorant. And it's not even their fault.

Now I say most adults are in that category, but I don't have data on that. I'm going by observed behaviour. We don't see a massive push against tracking / spying and even when it's thrown in our faces (eg: Snowden, Manning) we respond with a collective shoulder shrug.

It's always fascinating to see how complex modern hardware actually is. Dozens of small processors with their own operating systems communicating with each other. I have a lot of respect for the engineers that they actually managed to build a decide so small yet so complex.

Your "computer" is no longer just a computer, it's a whole network of computers in itself!

Neither hackers and the NSA right?

Exactly. It is cryptographically secured.

Tor Network is also encrypted and still there are ways to get the people behind. If the feature is there it will be exploited.

If you have any information about vulnerabilities in the published specs for the system, do present them.

Where can I read about these? Audio beacons, I mean.

yeah, also thought of this. An iPhone is essentially a small network of interconnected processors communicating with each other!
