https://github.com/pkolaczk/fclones can do the same thing, and it's perfectly free and open source. terminal based though
Is this the dedup function provided by other FS?
I think the term to search for is reflink. Btrfs is one example: https://btrfs.readthedocs.io/en/latest/Reflink.html Like with Hyperspace, you would need to use a tool that can identify which files are duplicates, and then convert them into reflinks.
The fact that copying doesn't copy seems dangerous. Like what if I wanted to copy for the purpose of modifying the file while retaining the original. A trivial example of this might be I have a meme template and I want to write text in it while still keeping a blank copy of the template. There's a place for alias file pointers, but lying to the user and pretending like an alias is a copy is bound to lead to unintende…

I thought reflink is provided by the underlying FS, and Hyperspace is a dedup tool that finds the duplicates.
When you asked about the filesystem, I assumed you were asking about which filesystem feature was being used, since hyperspace itself is not provided by the filesystem.
Someone else mentioned[0] fclones, which can do this task of finding and replacing duplicates with reflinks on more than just macOS, if you were looking for a userspace tool.

> it only found 1GB of savings on a 8.1GB folder. You "only" found that 12% of the space you are using is wasted? Am I reading this right?
The relevant number (missing from above) is the total amount of space on that storage device. If it saves 1GB on a 8TB drive, it's not a big win.
> There is no way for Hyperspace to cooperate with all other applications and macOS itself to coordinate a “safe” time for those files to be replaced, nor is there a way for Hyperspace for forcibly take exclusive control of those files. This got me wondering why the filesystem itself doesn't run a similar kind of deduplication process in the background. Presumably, it is at a level of abstraction where it could safel…
I still do not trust de-duplication software.

The part where he said making a large table in HTML and rendering it with a web view was orders of magnitude faster than using the SwiftUI native platform controls made me bash my head against my desk a couple times. What are we doing here, Apple.
Hacker News loves to hate Electron apps. In my experience ChatGPT on Mac (which I assume is fully native) is nearly impossible to use because I have a lot of large chats in my history but the website works much better and faster. ChatGPT website packed in Electron would've been much better. In fact, I am using a Chrome "PWA App" for ChatGPT now instead of the native app.
As a web dev, it’s been fun listening to Accidental Tech Podcast where Siracusa has been talking (or ranting) about the ins and outs of developing modern mac apps in Swift and SwiftUI.

https://github.com/tarkah/iced_table is a third-party widget for tables, but you can roll out your own or use other alternatives too
It's in Rust, not Swift, but I think switching from the latter to the former is easier than when moving away from many other popular languages.
