Randomness doesn't have any real impact on whether a problem is computable. Just model the distribution of the random variable. Non-deterministic Turing machines are a thing.

That's true. I suppose it comes down to what exactly is meant by "is computable". I don't think it was defined well enough, which I suppose is to be expected when discussing these topics that involve lots of hand-waving.

I interpreted it to mean that we can predict the outcome of it, you interpret it to mean that we can model it.

Either way, maybe it doesn't matter since the original proposal is that consciousness is a subjective experience and there isn't an obvious way to define how to programmatically create it i.e. compute it.

If it's physically grounded then it would be computable by some machine, just not necessarily a Turing machine. For instance, a hypercomputer can solve the Halting problem for Turing machines. We just have to be clear about the kind of machine on which a problem is computable.

It depends on if the universe is fundamentally deterministic or not. Right now we don't have any way to see beyond the apparent randomness in quantum mechanics and we probably never will. This part of the universe might be completely non-computable to us, it's just random.

I think -- roughly speaking -- Penrose argues that human capabilities such as transductive reasoning are clearly not computable, therefore falsifying the idea that the mind reduces to an algorithm. He then goes on to propose how nonetheless what the mind does might be physically grounded, even if not in purely computational machinery.

That wasn't the impression I got from Sabine's video. It's consciousness itself (the subjective experience) that isn't computable (AI will probably never be conscious).

They removed Secure Delete because it doesn't work with SSDs due to the way they work at the hardware level (wear leveling).

I would add: A useable System Preferences app. It's been renamed "Settings" and some idiot tried to make it look like iOS.

It's the absolute worst part of modern MacOS IMHO. As a Mac user measured in decades, it's the thing most likely to drive me back to Linux.

[edit: I am curious why this topic has been flagged]

Also a Mac user for nearly 2 decades. I don't care too much about most of the things mentioned in the article but I absolutely agree with you about the new System Prefs.

Why does this seem like such a hard problem to solve for everyone that isn’t Apple, when Apple seemingly solved the Trackpad over a decade ago?

Is this it? An unknown ROI?

>the highly uncertain ROI for trying to align touchpad acceleration has prevented us from proposing a system change to the default Linux settings.

I can only speak for myself, but I gave up using trackpads on anything that isn’t a MacBook many years ago. Very occasionally I’ll try them and have always been disappointed. This prevents me from buying any laptop that isn’t a Mac and prevents me from running any OS that isn’t macOS on a laptop. I can’t be the only person who prioritizes the quality and feel of input devices when choosing a system. If this can make or break sales and adoption, it seems like the ROI would be pretty good. Even if we are just talking about Java app, if I’m using an obviously Java app that feels like a clunky Java app, I’ll usually find an alternative app that doesn’t feel horrible to use.

I’m glad progress is being made, but I struggle to understand why it’s still a problem at all when it’s been so good for so long with Apple. They even sell Bluetooth trackpads for desktops it’s so good.

I feel exactly the same as you do. I switched to MacBooks in 2007 primarily because of how much better the trackpad was than the Windows and Linux laptops I had. Still using a MacBook, haven't looked back.

Yep. We have to use WhatsApp. There's no other choice. Texting between Android and iPhone is completely broken.

mb64 · 2 years ago

How so? I have iPhone and have a group text with 3 family members on android and it seems to work fine.
