How Apple Developed The Watch Ultra’s Advanced Endurance And Workout Features, by Dan Grabham, Stuff

“If you think about how GPS works, we are computing the distance between you and the satellites that are 20,000 kilometres above you,” explains Ron Huang. “They’re doing that by doing very precise timing between the satellites and your watch with these signals that are travelling at speed of light. So it’s easily perturbed and easy to incur some error from things like passing through different layers of the atmosphere. There’s a particular band of the atmosphere called the ionsphere that has a lot of plasma that disrupts the radio waves for example. Because L1 and L5 are 400 MHz apart, you can independently correct for that kind of effect.

“But it really becomes special when you combine it with [our] custom algorithms. So for example, we monitor and model your entire arm swing while you’re running so we’re not catching the speed of your arm swing, but the speed of your run.”

The iPad Is A Landscape-First Device In 2022, by Matt Birchler, Birchtree

With all due respect, I don't care. Apple designs their products and everything is a dance inside these computers to make everything work together. While I can appreciate the challenge this might create for Apple's designers, that's really not my problem, and the camera setup is plainly wrong and needs to be fixed.

Who Gets The Last Word On Steve Jobs? He Might., by Tripp Mickle, New York Times

The result, for now, is more of a tribute website than an archive. More than a dozen archivists and scholars who spoke to The New York Times questioned even calling it an archive. It has worried historians who fear it may inspire other wealthy and influential figures to curate the historical record about them just as ordinary people curate their lives on Instagram.

“One of the things that excites me about archives is the warts and all,” said Courtney Chartier, an archivist at Columbia University who has worked on Martin Luther King Jr.’s archive and the papers of Tony Kushner, the playwright. “People are complicated, and that’s something we shouldn’t shy away from.”

Bono Again Apologizes For U2's iTunes Stunt: 'I Take Full Responsibility', by Daniel Kreps, Rolling Stone

“I’d thought if we could just put our music within reach of people, they might choose to reach out toward it. Not quite.
