WorldDev··on iOS: Apps persist data after full deletion
Yes, I think that's right, you've found the root of the issue. Thanks for that link. Not great, I expected better from Apple.
WorldDev··on iOS: Apps persist data after full deletion
Right, but I deleted the app and all its data. I made sure there was no other app from the same vendor left on the device.

I checked the "Passwords" and there was no entry for these apps (I think that's the only place for the keychain on ios?).

And it's not about the phone telling its phone number.

WorldDev··on iOS: Apps persist data after full deletion
I tried that, and it still has access to account username on reinstall.
WorldDev··on iOS: Apps persist data after full deletion
No, I made sure I had only instagram installed and no other app from the same vendor.
WorldDev··on Ask HN: What AI tool to use for coding in 2025?
Got it, thanks
WorldDev··on Ask HN: What AI tool to use for coding in 2025?
Interesting, thank you. Did you compare it to other methods and found it better?
WorldDev··on Ask HN: Security of Hardware Nano KVM
That makes sense, thanks!
WorldDev··on Ask HN: Advice for creating a USB device linking 2 computers
Thanks for the idea. I think it's a great one, but I have a few concerns:

1) The two computers are on 2 different grounds, so I believe it could damage the computers. So I would like to isolate the ground somehow, I am not sure what the options are. I tried to look for opto-isolated options, but didn't really find something clear. Do you have any suggestion?

2) This specific chip is marked NRND (not recommended for new designs) on ftdi's website, So it feels slightly wrong to use it?

WorldDev··on Ask HN: Control 2 air-gapped computers with 1 mouse and keyboard
I see, you are unplugging and re-plugging, instead of just pressing a button. That makes sense. It feels like a usb mechanical switch should exist, but I guess it does not.

Another option that I looked at is whether I could use the switching capability on the device itself. For example the new Logitech MX 4 can switch between different computers. It also has a wireless connection, versus bluetooth connection. Do you have a sense whether switching with a device like that is enough of a separation?

WorldDev··on Ask HN: Control 2 air-gapped computers with 1 mouse and keyboard
That's interesting, thanks for sharing.

> Modern peripherals may have local storage

Do you mean the flash that contains the code for the microcontroller?

> I have a dumb USB switch

I am not 100% sure I understood. Is the "dumb USB switch" the paperclip?

WorldDev··on Ask HN: Advice for creating a USB device linking 2 computers
No problem at all, I didn't interpret it as sarcastic.
WorldDev··on Ask HN: Advice for creating a USB device linking 2 computers
Well, nothing malicious, and it would be to use between 2 of my own computers.
WorldDev··on Ask HN: Advice for creating a USB device linking 2 computers
Thanks for your thoughts. That all sound fair.

I am fine with having quite a bit of configuration on the target device (I am fine with configuration on both sides).

> it ought be possible to make a rpi0 device that outputs a usb-gadget keyboard

I like very much the idea of being able to make the host side (macBook) appear as a usb-gadget keyboard. That way I would just need to plug a single usb cable between the 2 computers. Could you give me a few pointers to get started, to do this on macOS?

WorldDev··on Ask HN: Advice for creating a USB device linking 2 computers
Thanks for that, that's an interesting thought. I am trying to think about the security aspect. If the receiving device (mac mini) is infected with malware, can it infect the macBook through the serial port?
WorldDev··on Ask HN: Advice for creating a USB device linking 2 computers
That's absolutely fair, and I am fine with writing software for both computers. However, I need this software to not go via the network at all.
WorldDev··on Ask HN: Advice for creating a USB device linking 2 computers
To try and clarify a bit: I am essentially trying to have a KM (KVM without the V) over USB.

To go one step higher, I am trying to control a mac mini from the keyboard of a macBook.

WorldDev··on Ask HN: Advice for creating a USB device linking 2 computers
Thanks, but I want to avoid IP. I want a system that does not go via the network at all.
WorldDev··on Ask HN: Advice for creating a USB device linking 2 computers
Thanks for your thoughts. I agree that using software would be easier, but I wanted to do it in hardware in this specific case.

I am unfamiliar with Raspberry pi, but if my understanding is correct, it's running a real os. So I would need to send it a command to actually shut down every time I want to remove the usb device. More generally, having a general purpose OS on the little device seems overkill for that use case, no?

WorldDev··on Ask HN: Hardware to use MacBook keyboard and trackpad to control Mac mini
Understood, thanks for your thoughts!
WorldDev··on Ask HN: Hardware to use MacBook keyboard and trackpad to control Mac mini
Interesting, I don't know these.

I assume you have a little software on the controlling computer that sends keystrokes over the network, they are received by this device, and sent via usb to the controller computer, simulating a usb keyboard?

Do you have experience with it? How is the latency? Does it work with the macbook trackpad?

WorldDev··on Ask HN: Hardware to use MacBook keyboard and trackpad to control Mac mini
Thanks for the pointers. The two devices are in 2 distinct security perimeters. So I was hoping to avoid software that link the two. I don't know if malware could use these software to propagate from one of the device to the other.
WorldDev··on Ask HN: How do GPS tracking devices send signal
Ah, that makes sense. Thanks for the explanation.
WorldDev··on Ask HN: Device for Music and GPS
Thanks for that suggestion. I thought that AirTag could not be used to monitor kid location though, as they will deactivate if far from the original iPhone.
WorldDev··on Ask HN: Device for Music and GPS
Nope, just 2 independent features, in 1 device.
WorldDev··on Ask HN: Device for Music and GPS
I can look into flip phones, yes, that's a reasonable approach. I was hoping to avoid all the rest of the phone functionality.
WorldDev··on Ask HN: Device for Music and GPS
That's fair. Definitely a solution, but I was hoping to avoid that.
WorldDev··on Ask HN: CVEs Comparison Brave vs. Firefox. Incorrect CVEs for Brave?
Regardless of this point, why are 0 CVEs for Chrome also CVEs for Brave?
WorldDev··on Ask HN: CVEs Comparison Brave vs. Firefox. Incorrect CVEs for Brave?
Yes, I have seen that argument often. I agree number of CVEs is a very rough metric. However, I am still confused as to why none of Chrome's CVEs would be Brave's CVEs?
WorldDev··on Chess: Chinese World Champion Disappeared
5 months is a long time, and he's "disappeared" in the sense that there has been no communication from him. It's not just a matter of not playing chess.
WorldDev··on Ethical Capitalism
I am willing to be a bit more generous in my interpretation, and assume it comes more from the difficulty of solving problems as a central authority, rather than cynical egotism. But I can see how one can arrives to your viewpoint, and in any case I think we both arrive to the same conclusion: expecting the current forms of governments to solve modern problems is doomed to fail.
