@viticci I think I have an answer, too: programming languages provide the highly-enforced structure and sanity-checking that LLMs need to excel. It's like the (defunct) left brain vs right brain idea — one side for creativity, one side for logic. A dreamer, and a thinker. Together, it keeps concepts well enough in check to create some amazing things.

I think we don't (yet) have that for prose, or music. But I could see it being possible, if we invent and teach the right abstraction layers

If you have a Mac app that displays its own icon somewhere in the UI, it can end up showing the incorrect icon if the user's icon style changes while the app is running. Here's a SwiftUI view that can handle that and always display the icon that matches the current system style: https://gist.github.com/insidegui/686ae55087542b430be976918418d129

Super excited to bring back the Stacktrace podcast (again!), with monthly episodes starting... right now! 😀

205: “The 2026 edition” | Stacktrace

On this first episode of the 2026 season, John and Rambo discuss how they’re using AI agents when working on different projects, and how to approach learning new programming languages in 2026.

Recap: I vibecoded (code unseen, no plan) a 3D editor/renderer that has a scene graph, editing controls, primitives and gizmos, materials, procedural terrain and water, and hardware-accelerated Metal raytracing with soft shadows, clouds and bounce lighting, that runs on Mac and iPad.

Tool: Codex 5.3 Medium
Time: About a day's worth of work has gone into it

I was reading a post made by @_inside where he demonstrates the usage of CloudKit for content hosting and feature flags.

This triggered something in my mind: if CloudKit has an HTTP API, it can be used as a feature flag control in Kotlin Multiplatform solutions.

I was reading a post made by Gui Rambo where he demonstrates the usage of CloudKit for content hosting and feature flags. In there, he mentions:

This post by @_inside is THE post to read if you want to understand CloudKit security roles (and how to assign them!)

Thanks, Gui. You're a lifesaver.

I'm glad I did this 😅

Speaking of the quality of Apple's Private Cloud Compute model…

💜 A year ago today we lost one of the kindest, most-generous developers in the Mac community, Martin Pilkington (pilky). He was known for and worked on many projects over the years, but Coppice was his labor of love. I have been working the past couple of months on rebuilding Coppice for macOS 26, Liquid Glass, and the App Store, and I'm thrilled that today is the day I get to release it into the world — with all of its previously-'Pro' features available for free

TIL about this "CustomAvailability" experimental feature in Swift. Looks like Apple is using it for feature flags 👀
