ABSTRACT
Many of us use collaboration software such as Google Docs, Overleaf, Figma, or Trello every day. While this cloud software is very valuable, it is also fragile: if the company providing it goes out of business, or decides to suspend your account, the software stops working, and you are locked out of all of the documents and data you ever created with that software.
Local-first software is an effort to make collaboration software less dependent on cloud services, and Automerge is an open-source library for realising local-first software. Automerge uses Conflict-free Replicated Data Types (CRDTs) to allow several users to concurrently update a file, and it automatically merges those updates into a consistent result. It provides data formats for efficiently storing this data and syncing it between users. It seamlessly supports both offline work and live real-time collaboration while users are online.
This talk will introduce our recent research on CRDTs, and provide an update on the latest developments in Automerge. [...]

Wow. Simply, wow. I love Martin, he really takes his pet projects to the next level!!
I feel like that I have seen this presentation a number of times now over the years. The example for each of the 4 algorithms are all different so they are not comparable. In the last rich text example both user A and B end up with something neither have seen. It should be easy to construct a sentence that result in merged nonsense (i.e. if annotations have order requirements perhaps?).
Very cool❤😂🎉
It seems a thick client has been reinvented again
but now it is backed by git
There are a lot of benefits I see with this, but, if you're using a browser, wouldn't it be easy to use DevTools to bypass security? Isn't that one of the main benefits of having a backend API?
That's what he went over when he started talking about what local-first software is a good fit for vs. what it's not a good fit for. Around 15:30
There's also the option of having a local database on the browser, which just a client-side view of the current state of the system, and have the actual system of record still in a regular backend server.
So basically, it's a desktop app running on a browser.
All the rules usually implemented on the backend side still have to be implemented on the frond end side.
I'm curious about the performance as well. You can't be sure about the client processing power. On the backend side, everybody has access to the same power.
I'll add that it's hard to get ride of a centralised database for stuff like authentication etc etc
I was excited about this talk, disappointed 😞
