I don't have much experience in this area, but I'd be interested in an overview of how different pieces of sofware handle the concurrent / multiplayer editing problem, like:
- Etherpad
- Google docs
- Apache / Google Wave (open sourced: http://incubator.apache.org/projects/wave.html)
- repl.it https://repl.it/site/blog/multi
- figma https://www.figma.com/blog/multiplayer-editing-in-figma/ (image editing rather than text editing)
So is the gist of it that OT relies on central servers and they all use OT rather than CRDT? That was not entirely clear to me.
Looking at the xi analysis, it sounds like "IME" is specific to a desktop application using X (?), so it doesn't apply to any of this web software.
The rest of them seem like they do apply?
Is the problem that you have to pay a "CRDT tax" for every piece of state in the application? I thought the same was true of OT. Don't you have to express every piece of state within those constraints too?
repl.it doesn't seem to have a problem with syntax highlighting or brace matching (try it, it's pretty slick). So is it just that they paid that tax with a lot of code or is there something else fundamentally different about xi vs. repl.it ? Or maybe xi is going for a lot lower latency than web-based editors?
recent thread about OT vs. CRDT that might be interesting: https://news.ycombinator.com/item?id=18191867
