The goal here is neutral buoyancy when in gravity so that it behaves as though there were no gravity. Put a bag of water in water and it floats like the rest of the water, gravity or no.

In System Settings > Keyboard Shortcuts > App Shortcuts, add the shortcut: app Safari, name "Quit Safari", command-option-Q. This will leave command-Q doing nothing, yet still allow you to quit. Repeat for other apps.

That outfit was typical of clowns in 1890, and often used in the opera Pagliacci about a clown.

If it’s showing surface winds, it goes up. On windy.com there’s an altitude slider that lets you choose which wind level you’re looking at. Haven’t found that yet here.

I'd like to see the internet return to those who aren't putting it out there for money, so AI companies (and anyone else) hoovering it up wouldn't bother them. Sharing should be the point.

Would also result in fewer sites with ads -- yay!

GPT5.2 does catch it and warns to not trust anything else in the post, saying no competent person would confuse these units.

I wonder if even the simplest LLM would make this particular mistake.

That's odd. ChatGPT (5.1) tells me Safari does not open an audio capture session for 'capability negotiation' that would show the mic icon.

I assume you have Safari > Settings > Websites > Microphone > facebook.com set to the default "Ask", or to "Deny"? Also check any installed extensions.

ChatGPT 5.1-Thinking, after having this pointed out: Short answer: no, your version isn’t the classic one, and my previous answer treated it as if it were. That was me pattern-matching too fast.

There are other possibilities, the most likely being that the slide was already in the process of breaking when the child used it last, and he noticed that before others did.

Yes, I've seen occasional strange responses to seemingly innocuous prompts. Often a retry will succeed, but I've had to give up on some.

I doubt it's the model itself in most cases, as it doesn't have much introspection. Its explanations will be what it can deduce from whatever it does have.

Ask ChatGPT to explain what it's drawing as it adds parts. It's usually more successful. Or at least entertaining. Reminds me of how a young child draws.

>Maybe if Mac had got their shit together with the keyboard (swapped ctrl and super key)

The command key has always been where it is. And it works quite nicely there, being under your left thumb, allowing you to type common commands from rest position in one stroke.

The Windows/super key came 10 years later, the swapping being Microsoft's choice.

New comment by pulvinar in "Battery charge limiter for Apple Silicon MacBook devices"

pulvinar — Sun, 10 Aug 2025 19:39:51 +0000

I could swear my MacBook Air M3 was limiting at 80% charge before, but now it's at 100%. I suspect that the latest OS update, 15.6, disabled or removed whatever was limiting it, but I don't remember what that was.

It doesn't look like I had installed this "battery" command. It might have been AlDente, but I don't find that anywhere either.

A puzzler.
