Matrix-CRDT VS syncthing-android

Another interesting and peculiar approach would be to use Matrix, which is chat and collaboration framework that is completely decentralised. Essentially, in this way Scrivano would translate pen input into chat messages that are sent to other users who receive them in real time. One advantage of this approach is that the collaborative notes will remain accessible even after you go offline and multiple users will be able to collaborate on a single note just like they would in a group chat. There are already apps that make use of this idea (e.g. see Matrix-CRDT or TheBoard), but when I tried this it last time didn't work very well and I'm not sure whether this is a limitation of the service or of the specific implementation I tried.

1. This is complicated. There is a notion of power_level, which you can set to different events. So you can set "send message" to power level 30, and any user with a "power level" of 30 or more will be able to send messages. Those power levels (and the required level to send an event) are granted by the room creator.

There is, however, no power_level associated with reading messages. I think you need to be joined to a room to send messages, and to be joined, you need to be able to read messages by design. So the "inbox" model doesn't seem representable to me. But maybe I'm missing something!

2. Yes. Events can refer to prior events to modify them, e.g. you can "edit" a previous message by appending a new message of type "msg.edit" (made up type, not sure what the exact it), specifying the old message id, and the new text. For matrix-based CRDT, see Matrix-CRDT[1], a Yjs backend using Matrix.

Have you checked out Matrix? It's specifically a protocol (they've used OpenWhisper) but people are using it like a social media platform (specifically like IRC). There's even people doing google docs like services. I'm going to link a HN thread from that last link because others are just talking about Matrix and that'll likely be helpful to you.

We use syncthing to share files between our machines. It avoids is having to use dropbox / OneDrive etc. You just choose a folder and it automatically syncs it in the background.

This very hn entries is bust contradicting your statement.

Also what about syncthing[1] (for recurrent/permanent sync) and croc[2] (for one time copies) ?

I have used both for a number of years already.

I would use syncthing, which is open source at https://syncthing.net/.

After minimal setup, it just works(tm).

You have a normal directory in your filesystem, that is synced to the other peers (which you set up in the "minimal setup").

I have been using it for years, and it works well. It has no problems crossing os'es (i.e. windows -> linux, linux -> mac)

For windows I usually recommend https://github.com/canton7/SyncTrayzor, but vanilla syncthing works fine too (but don't try to mix them!)

Do consider Syncthing particularly if you are using Android. If using apple iOS you'd need the möbius sync client.

One thing that it beats the cloud / centralized sync on is because the connection is direct between devices when the initial transfer is completed the file is completely there on the other device. With a cloud type of sync you do the transfer twice. I've seen stack up on large media or with the structure of cloud services pricing making it expensive depending on how your workflow is setup with inside and outside parties. For example, Dropbox deduction from all parties' storage limits not just the sharer.

You can also point Syncthing at a local sync of Dropbox or Google drive and then forward the files to other recipients from that for some purposes.

I think sync is a non-feature, as you can just ride on your existing solution.

For example, I use syncthing [1] with Obsidian to sync files off-cloud.

When I was 14 and just getting started, I used Notepad. Upgraded to Wordpad when I realized I loved putting italics in every other sentence, moved to Google Docs at around 25 when I started writing on my phone and wanted to sync with my computer, finally moved to Obsidian a few months ago (with Syncthing for syncing) when I decided I don't want to live in Google's house where they can burn my stuff down whenever they want.

Pick it up again an use cloud syncing this time! Is worth! https://syncthing.net/
