How do you handle hash collision?

Very cool. I would love to have something like this production ready. Some day...

Anyone who finds this interesting may also be intrigued by Irmin [0] - a library for applications to persist data in a git-compatible format.

Those are exactly the kind of ideas the finance world needs to get out of its ethernal mess of spreadsheets.

Strawman marketing alert: "The most common way to share data today is to post CSV files on a website". Maybe there are a bunch of people that still do that somewhere, but if so, they ain't early adopters of decentralized database technology and so not your target customers. It's always better to talk about what your most likely customers are doing now.

Earlier quoted context omitted.

You probably want to prepend a "Show HN: "

Whoops -- @ahl says it's too late now.

Added.

Yeah, that totally made me laugh. Good point about the target audience.

This is really interesting! What are some ideal use cases for the current implementation? I've seen Git is considered a competitor, but Noms also appears to be a generic database, so i would just like to hear some basic use cases, if possible.

Eg: If used as a database, what applications would benefit from Noms? Could/should this be used for personal storage? Could/should this be used for code versioning (ie, Git)?

Excellent! This has been on my "things to build someday" list for a while now. Excited to start playing with it.

Same here, though in my case it was on my list of things to continue building.

Can you elaborate a bit on how the hashing and chunking works? There's a rolling hash for determining chunk boundaries, and also SHA-512/256 somewhere.

Does the same data chunked differently have a different hash?

I'm surprised you didn't use a functional language like Haskell or OCaml or Rust to do this, since the article talks about love for functional programming.

I'm not criticizing Go at all, it's just not really a functional language.
