Seeing all the M5 Max MBP benchmarks roll in is making it hard to wait for M5 Ultra!
Still slumming it with my M1 Max...
From empty repo to a functional minimal standalone terminal based on libghostty in less than 2 hours, presenting Ghostling! ~600 lines of C and you get extremely accurate, performant, and proven terminal emulation. Every program on earth that needs any subset of terminal functionality and can now easily get it.

The libghostty C API is not formally released, but I built this project to prove its ready to go. 😎 https://github.com/ghostty-org/ghostling
Nuts. In four hours I rebuilt an iOS app that I had spent months on before AI.
Still needs UX polishing but the code is good enough and a lot more consistent than my version.
Admittedly, it did help when the AI screwed up a piece here or there to tell it to consult the old app to see how I fixed it and do something similar. But I took a freaking day to do a tricky layout thing, and after I described it conceptually it one-shot it.
But I threw the SwiftUI stuff in the bin, if the AI is writing the code UIKit is better from a performance and ability to access more platform functionality perspective. It is buttery smooth now for pieces where SwiftUI was a bit choppy.
I only open up Xcode to press Command-R 🤣
Everything else happens in Claude Code.
Surprisingly different experience using Claude Code in terminal to create an iOS app vs the new Claude Agent in Xcode.
Terminal Claude Code one-shots tasks, Xcode spins its wheels a long time and doesn't get it right after several tries.
I wonder if Anthropic or Apple created the agent harness for Xcode, I suspect Apple (UI looks nice, but it doesn't work well).
Or I just know how to drive Claude Code better.
Both are using the same Claude Max account with Opus 4.6.
If there was a 1Password replacement that worked on Windows/Linux also I would drop it today.
Right around subscription renewal time, every interaction with this thing requires entering my password again, if it even activates.
It is such a piece of shit now.
