https://repl.it/site/blog/collab for anyone interested in an overview of a real-time distributed code editor featuring both channels and operational transforms. replit seems to be doing really solid (if unimaginative, wrt this group’s values) work

I'm surprised they went with OT rather than CRDTs. I've heard it's far, far harder to do a correct implementation of OT.

I have heard that too. But I guess OT are here since longer time than CRDT, and also a more natural choice at some point.

At the top of the blog post they mention in their old system there was the problem that one person is debugging and another person would be editing the code under them messing up their debugging. It didn't seem like they covered how their new system fixed that problem. Did I miss it?

I agree. They describe the new system (bzsed on channels) but don't give details on how they actually resolve the intent conflict.

Maybe they didn't see Causal Trees at http://archagon.net/blog/2018/03/24/data-laced-with-history/
