  The promise of the cloud was that you don't need local storage, because Someone Else will remember things for you, and you just ask them what you remember. This is also the problem of the cloud.

    "The promise of the cloud was that you don't need local storage, because Someone Else will remember things for you ..." Agreed. And that promise has been fulfilled - although it costs more than nothing and you need to do your homework. You know these providers are proven bad actors. You know their business model(s) are antagonistic to your goals. You also know there are stable, time-tested alternatives. What did you think was going to happen here ?

      I would say at least partially aligned with your goals otherwise why would you use them in the first place?

        They’re unaligned with rsync.net’s goal of getting people to pay for services. Edit: to pay a minimum of $12/month??

  ok and then what? :D you still can't recover original

> slightly different every time we look back, but with no way of knowing what's changed This is already the case with different image compression algorithms improving on one another. Users couldn't and shouldn't tell the difference between JPG, or slightly smaller / resized JPG, or WebP, or whatever. I personally don't think image hosts should have to alert users when making undetectable changes to their images like this.

  I'm sorry, but JPEG compression is extremely noticable especially with non-photographic material such as web graphics. The compression is lossy by nature, and predictably introduces noticeable artifacts. WebP on the other hand has support for lossless encoding. It's simply not the same thing. If I opened my file browser one day and saw that all of my FLACs had been converted to MP3, I would go on a murder spree.

"Soon, digital memories will be just like real ones — slightly different every time we look back, but with no way of knowing what's changed ..." Well, let's see: ssh user@rsync.net sha256 photos/IMG_1234.HEIC Yep, checks out.

  Sadly, you stored only the MD5 back then.
  - rsync 4y ago
    We don't store any checksums - we just store your files. The checksum commands: (md5, sha1, sha224, sha256, sha384, sha512, sha512t256, rmd160, skein256, skein512, skein1024, cksum) ... are available to run as you see fit.

      I think you misinterpreted the comment you're responding to; they meant that "sadly, you [the user] never thought to store a high-quality hash (e.g. SHA256) for integrity comparison with your stored data; and the hash you did decide to archive for integrity-comparison was a low-quality one (e.g. MD5) that can be trivially preimage-attacked such that a cloud provider could silently replace your data with a different one — with the same low-quality hash — without your knowledge." Nothing about rsync.net per se, other than the general idea that any data you put on "somebody else's server" can't be trusted to stay the same if you don't have a high-quality integrity-comparison content-hash of that data kept somewhere.

        MD5 still has no known preimage attacks. Neither does MD4, for which collisions are absolutely trivial to generate.

How can your Photos library be real if our eyes aren't real? /s

> Nothing a little Stable Diffusion can't fix. As someone who works in generative modeling, that's probably what is creating these issues in the first place. Kinda like how you can see certain GAN type of patterns on Netflix when there is upscaling or if you don't turn off the fancy features on your TVs. Of course, finding how these images are corrupted leads to better models so they will be solved. This isn't the first time Google has edited photos and made them worse and it won't be the last. But the trend is that the photos get better.
