I'm submitting this because I'm not sure if something is wrong with my machine, or if there's a kernel bug that can be reproduced on another machine. I've been able to reproduce this issue on my machine twice in a row.

I have a 16-inch Nov 2024 M4 Pro MacBook Pro for my job. It's enrolled in AppleSeed as part of our internal beta testing.

One of the tasks I'm working on is building an IntelliJ IDEA plugin for our internal configuration system. As part of an enhancement I've been working on, I've needed to get several samples of PSI structures from the IDE. If you've worked with the IntelliJ Platform SDK, you know these PSI structures can be absolutely massive, especially if you need to copy and paste them to save them to files.

I tried to save one of these PSI structures to a file so I could analyze it more closely. I pressed Copy PSI in the IDE, opened Neovim in Ghostty to paste, and pressed the paste shortcut... and my system locked up and hard-crashed.

I tried it again when I rebooted, and the system hard crashed again.

I'm not sure how long the actual string I was copying and pasting is, but I know it's probably absolutely massive.

The problem is that I can't figure out if this is a Ghostty issue or a system issue. Ghostty is fully up to date.

Is anyone able to reproduce this issue?

Hey HN,

This is a full open-source rewrite of The Sound of Sorting — the classic algorithm visualizer — built entirely in Swift with SwiftUI for macOS and iPadOS.

Originally intended as a straight port, it quickly became a much deeper project: a ground-up redesign focused on code quality, educational value, and cross-platform Apple support.

Highlights:

Real-time visual and audible sorting animations

Detailed explanations of each algorithm

Time & space complexity breakdowns

Code implementations in 10 different languages (and growing)

A fully custom syntax highlighter written in Swift

Modular architecture for adding new algorithms or languages easily

This has been my longest-running personal project — I started it in late 2021 as my first Swift app, and it’s now become a platform for exploring everything from AVFoundation to SwiftUI best practices.

Why I’m sharing: I’d love feedback, ideas, and especially contributions. There’s plenty of room for improvements: better performance, more algorithms, expanded language support, accessibility enhancements — you name it. Even reviewing the Swift code and helping improve the idiomatic use of the language would be hugely appreciated.

If you’re into open-source, visual learning tools, Swift, or just love making things better — I’d be thrilled to collaborate.

The code is available here: https://github.com/nhubbard/sort-visualizer-swift

And the app is available for download from the Mac and iPadOS App Store here: https://apps.apple.com/us/app/sort-symphony/id6477886990

Thanks!
