I love how you can type something into the search field in the Xcode documentation browser and nothing happens, no loading indicator, no nothing, and then, just when you’re about to start wondering if the window is frozen, the search results pop up.

Cory Doctorow describes why I’m personally not interested in AI-generated art very well in his interview on Decoder.

Finally received my 17 Pro. First impressions: it feels like a toy phone after coming from a 15 Pro Max. I’m still not completely sold on the new back design, but it does feel great in the hand.

I have been rehearsing and I just cannot remember to say this. So here’s a spoiler from my talk in case I forget again:
“Approachable Concurrency” is just a big group of settings. It is completely independent of making the default isolation MainActor.

Got inspired by one of @avanderlee.com's posts a while back and started labeling my issues based on effort and impact. I also set up a project that automatically pulls in low-effort tasks from my various repos. I’ve found this really useful for surfacing tasks I can pick up when I have limited time.

It’s really inspiring to see everyone release their app updates today! My initial plan was to have a 1.0 ready for release day, but didn’t get as much done during the summer as I had hoped. Hopefully I’ll get to be part of the day-one crew next year 😃

Preordered an iPhone 17 Pro in silver. Almost went with the base model now that it has ProMotion, and I think it looks better, but didn’t want to lose camera features.

Thinking about preordering a new phone on Friday, and now that they have ProMotion, I’m tempted to go with the base model. I think it looks better than the Pro, and it would be nice to have a lighter phone. I’m just not sure how much I’d miss the telephoto lens and the screen size of my 15 Pro Max.
