AI Thread Summary
To set the TI-89 calculator to define a function with restrictions such as "x does not equal 3" and "x does not equal 4," use the notation "x ≠ 3" and "x ≠ 4." The "≠" symbol can be accessed by pressing the diamond key followed by the equal sign. The logical conjunction "and" can be entered manually as the string "and" or by using a menu item for convenience. This setup allows for proper function definition while accounting for specific exclusions in the variable x.

... | x =/= 3 and x =/= 4

The =/= being the = sign with the slash through it, available through diamond + =

The and is literally the string "and" which you can type in manually. I prefer to keep a menu item for it. :)

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...

Thread 'Is AI hype?'

In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...
