Nice, but I'm not getting a subscription for a filesystem utility. Had it been a one-time $5 license, I would have bought it. At the current price, it's literally cheaper to put files in a S3 bucket or outright buy an SSD.

I can't even find the price anywhere. Do you have to install the software to see it?
The Mac App Store page has the pricing at the bottom in the In-App Purchases section..
TL;DR - $49 for a lifetime subscription, or $19/year or $9/month.
It could definitely be easier to find.

#223I don't understand why a simple, closed source de-dup app is at the top of the front page with 160+ comments? What is so interesting about it? I read the blog and the comments here and I still don't get it.

Re: Hyperspace
#224> Like all my apps, Hyperspace is a bit difficult to explain. I’ve attempted to do so, at length, in the Hyperspace documentation. I hope it makes enough sense to enough people that it will be a useful addition to the Mac ecosystem. Am I missing something, or isn't it a "file de-duplicator" with a nice UI/UX? Sounds pretty simple to describe, and tells you why it's useful with just two words.
The author of the software is a file system enthusiast (so much that in the podcast he's a part of they have a dedicated sound effect every time "filesystem" comes up), a long time blogger and macOS reviewer. So you'll have to see it in that context while documenting every bit and the technical details behind it is important to him...even if it's longer than a tag line on a landing page.
In times where documentation is often an afterthought, and technical details get hidden away from users all the time ("Ooops some error occurred") this should be celebrated.
Re: Hyperspace
#225For those mentioning that there's no price listed, it's not that easy as in the App Store the price varies by country. You can open the App Store link and then look at "In App Purchases" though. For me on the German store it looks like this: Unlock for One Year 22,99 € Unlock for One Month 9,99 € Lifetime Unlock 59,99 € So it supports both one time purchases and subscriptions. Depending on what you prefer. More about…

Re: Hyperspace
#226Earlier quoted context omitted.
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.
I thought reflink is provided by the underlying FS, and Hyperspace is a dedup tool that finds the duplicates.
You can do the same with `cp -c` on macOS, or `cp --reflink=always` on Linux, if your filesystem supports it.
Re: Hyperspace
#227> Hyperspace can’t be installed on “Macintosh HD” because macOS version 15 or later is required. macOS 15 was released in September 2024, this feels far too soon to deprecate older versions.

Re: Hyperspace
#229Earlier quoted context omitted.
At that point, why hash them instead of just using the first 1024 bytes as-is?
Probably because you need to keep a lot of those in memory.
I suspect that a computer with so many files that this would be useful probably has a lot of RAM in it, at least in the common case.

> Right, but the concept is the same, "remove duplicates" in order to save storage space. The duplicates aren't removed, though. Nothing changes from the POV of users or software that use those files, and you can continue to make changes to them independently.
De-duplication does not mean the duplicates completely disappear. If I download a deduplication utility I expect it to create some sort of soft/hard link. I definitely don’t want it to completely remove random files on the filesystem, that’s just going to wreak havoc.
But it can still wreak havoc if you use hardlinks or softlinks, because maybe there was a good reason for having a duplicate file! Imagine you have a photo “foo.jpg.” You make a copy of it “foo2.jpg” You’re planning on editing that file, but right now, it’s a duplicate. At this point you run your “deduper” that turns the second file into a hardlink. Then a few days later you go and edit the file, but wait, the original “backup” file is now modified too! You lost your original.
That’s why Copy-on-write clones are completely different than hardlinks.
