Did you know your MacBook has a sensor that knows the exact angle of the screen hinge?
It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

I have a list of patients I’ll remember forever, but some changed what kind of a doctor I am. I don’t mean what field, I mean I reassessed who I want to be and how I want to act. I owe them all a debt. Many years on, I still feel guilty about this one

I'm looking to buy a new laptop, and i can't believe 8GB RAM models are still being sold, while higher end models come with 64GB or more. That's a huge spread!
BTW, if you have any recommendations for a good Linux laptop, i'm all ears. I'm thinking of going for a ThinkPad T o P series.

so disappointing how many ppl I see preemptively convincing themselves they can't learn a thing w/o giving it a real effort over time bc they think natural aptitude is the defining factor of skill acquisition. the only diff btwn them & the ppl who can do the thing is that the latter just kept trying

A major problem with using LLMs to learn things:
Me: "A is true, therefore B is false, right?"
LLM: "Right! Here's a ton of detail to confirm your belief."
Me: "Actually, A is false; B is true."
LLM: "Exactly right! Here's more detail to confirm that belief."

They're putting blue food coloring in everything
"Why is my burger blue?" I asked, innocently.
"Oh! We're making all of our food blue, all the best restaurants are doing it now." the waiter explained.
But I didn't want my burger to be blue.

What a fantastic post. It gets deep *fast*, and remains gripping all the way.
It captures a lot of the negative sentiment i feel towards this industry. A big machine for making Whatever. No, not even that: making *money* of Whatever. That's the *only* thing that matters.
