606: A Decade of Half-Presses

So JPEG XL is on your iPhone. If you have a newish iPhone... And if you're shooting in raw and if you are, you can get files that are up to half the size that they used to be at about the same quality. So good thumbs up, but it is not the JPEG XL revolution that we had been waiting for. So I did change to JPEG XL. I think I went with lossless just because I'm shooting in raw.

I probably just, you know, I do it so rarely on my phone. I'll just pay the full cost of the size and it's still smaller than it used to be. So, you know, partial thumbs up on JPEG XL. Hopefully it will expand over the years.

I recall like way back in the PowerBook days, maybe, or maybe it was the MacBook days, there was similar indicator light and Apple made similar claims about how, well, it's impossible to hack this light because there's a hardware feature in the laptops that basically says when the camera is active, this light comes on.

Like this was an example of it not being software mediated at all, but it was something like, hey, if the camera's on, the light's on, there's no software environment. Software has no visibility into the light whatsoever. Can't turn it on, can't turn it off. It's just like an electrical fact of life about how we've connected the camera.

And even when they did that, I believe someone found a way to get the camera to turn on without the light going on. Like hackers are devious. So this exclave is, you know, in the game of cat and mouse, here's Apple's next move. It's like, oh yeah, let's make it even harder for you to get this light. Even if you have kernel access.

You still can't get at this because this is a different OS running in this secure exclave, which is this other little machine that you can't get to. The secure enclave is obviously where you can put secrets that are hard to get to if you're running on the main CPU SoC. But now we have the secure exclave, which is a whole other chip with a whole other OS. It's even harder to get to.

And I'm sure that's true. But hackers are very devious. So let's see how the next move goes. But anyway, Apple continues to try to make it very difficult. to spy using its products without using the easiest method, which is, of course, social engineering.

And they demonstrated. So we talked about this, I think, before the event where there was rumors of this happening. And I don't know how I pictured it like working. Maybe like you'd short something out and there'd be a puff of smoke and the battery would come out or it would just pop out or whatever. It is much less dramatic than that, but it is no less cool.

In the iFixit video, they take a little power supply and they hook it up to the battery. There's like a little metal, you know, contact that pops out for you to connect it to. And then you just connect something else to like ground inside the thing.

And you put some power into it for a few seconds, and it basically chemically changes the adhesive to make it not sticky anymore, and then the battery just comes out. And they explain a little bit how it works. Interestingly, if you reverse the polarity, where you put the plus and the minus on the opposite side, it will make it re-stick. What? But not to the thing.
