Also the internet is the primary attack vector for most devices. I don’t have to worry about someone hacking my devices that just do their job and don’t have internet connectivity.
That being said though, the internet-based devices in the article are simply becoming non-internet-based devices, so my suggestion is kinda a moot point.
There’s no center of the surface of the balloon (approximating the balloon as a sphere and ignoring the nipple).
If you are standing on the earth, there is no center of the surface of the earth. The actual center of the earth requires movement in the 3rd dimension, but the surface is 2 dimensional.
If our universe is hyper spherical, the “center” would be something unreachable; it would require moving in the 4th spacial dimension.
Honestly a foldable smartphone should be 2 touchscreens with a hinge if there’s at all any risk of a bendy screen breaking more easily or otherwise being inferior to that.
iTunes Music Store (it’s still around but can be hard to find because of Apple Music streaming service)
Amazon’s music store (but it’s crap quality and they put audio watermarks in it - don’t use them while the two above options exist)
Comixology before Amazon bought and deleted them
Occasionally there are websites where you can purchase video content for download, but it’s quite rare. I remember buying anime from such a site before.
My experience is with iPhone (yeah yeah boo Apple).
Most of how I learned was just digging through Apple’s documentation, focusing on one goal at a time. How do I draw stuff to the screen? How do I handle touch inputs? How do I use the built in UI elements? How do I play sounds? How do I get GPS data? Things like that. I’d usually have an idea of a specific mini-project that would make use of a specific new tool.
Note that I already had some programming experience (although it wasn’t much) before I started teaching myself this way.
Just start by downloading XCode and playing with one of their sample projects. SpriteKit is particularly easy to get started with and there’s a sample project for it. (I’m assuming you want to make something like a game. If you want to make more of a utility app, look up SwiftUI).
