Ah, they are talking about an inertial measuring unit. Basically, by measuring all acceleration you’ve experienced you can calculate your change in position. They can’t determine absolute position though, only relative, so this doesn’t so much replace GPS as assist it.

And caffeine in the coffee would be listed in milligrams, but the alcohol in beer and spirits would be measured in percent and proof.

“You may not instantly see why I bring the subject up, but that is because my mind works so phenomenally fast, and I am at a rough estimate thirty billion times more intelligent than you. Let me give you an example. Think of a number, any number.”

“Er, five,” said the mattress.

“Wrong,” said Marvin. “You see?”

Ooo! You’d think a double double is 4x so at 2x the price is a steal!

The Newton was before its time. So many features we use our phones for today were pioneered in the PDA era.

Interestingly, Apple has donated the phone version of MagSafe to the Qi open wireless charging standard. Soon we’ll see a magnetically aligning wireless charging Qi2 devices from other manufacturers.

For me, the Apple Watch is about reducing notifications to mere glances at my wrist. That instead of interrupting what I’m doing to pull my phone out of my pocket I can at a glance categorize what, if anything, I need to do in response to that notification. That and always accurate time to me was worth getting a watch. I upgraded from a series 3 to a series 6 when the sensor tech advanced enough to convince me to update. The 9 has some new stuff, but not enough to convince me to upgrade.

That looks like a type of Thin film interference, like you’d see on an oil slick or a soap bubble. Wikipedia says:

Thin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, either enhancing or reducing the reflected light.

I’d guess the display uses a thin film on one of its layers causing this rainbow interference pattern that shifts depending on viewing angle.

The good old Unix philosophy.

All very fair points. It’s all wildly complicated, and I agree; we don’t really understand ourselves.

What are your underlying models of the world built out of?

As a Bayesian, my models of the world are built on priors. That is, assumptions I’ve made based on my existing information. From that, I make an educated guess about the world with that model and see what the world does. If my guess doesn’t match reality, I update my assumptions to rebuild my model and repeat the process until it’s close enough.

This is the way the best science is done, and I fell it’s the way that humans really work. Language is just a type of model we use to communicate the world to others, each of us may have a slightly different Bayesian understanding of the language yet we can still communicate.
