You're welcome. It's not a bug, but just the library they use to upload files doesn't do chucking. There is a git hub request for it, but it's not done yet.
It's not that C is bad, but that it's a bad language in this use case. Rust doesn't let developers shoot themselves in the foot as easily as C, not to say that it can't be done.
The comment regarding developers being responsible is true, but they could make their job much easier and thus more accessible to others by using Rust and not being required to learn all the tricks to make C safer in such a critical piece of software.
This isn't a paid product/gig, so it's not necessarily attracting top C developers either.
C is great for specific user cases such as code that needs to be exceedingly performant, needs to access low-level devices, or is used on embedded applications.
On a project that doesn't have these requirements, I believe it is more important to be understandable and has a lower skill floor.
My only warning for a new user to Immich is that it does not support chunk uploading. So if you're like me and took a 1 hour 40GB 4k video, it will never upload. It will start, fail, and start over again forever.
My first linux distribution was Linux From Scratch (LFS). I printed like 300 pages at the school library so I could run it at home. My first real distribution was Gentoo or Damn Small Linux.
I can't get behind a browser built from scratch with C, not Rust, considering how integral browsers are to security these days. Plus there's the whole controversy around their pronouns and politics in coding stances.
I really liked Floorp, but it kept breaking on work sites, so I had to switch back to FF. Super glad they are bringing this back.
