infinoted/testing 0.7.1-1 amd64
  dedicated server for infinote-based collaborative editing

tiny note: tried to install it on a mac os (failed eventually after 30 min install time) and brew overwrote my prev python + other installations. :| luckily nothing broke! but it was a tiny moment of suprise... yes.... shit! my mistake for not installing it in a venv :S hope everything is oke again now! yep all good :] not sure though if you can install it in a venv, as it is an apt package. ah ok, i installed it through brew, so it's very possible that brew messed up. but very curious to try on a linux machine! haha, great merge of sentences ;). :P git merge, real-time syncing! ;) great document mb btw! i love the insertion of chatty notes :D ahah that's definitely something i can help with :O hehe ! We have a great color match as well atm. ;) so 90s, i use to love pink and purple combinations. hahaha yes all we need is another light green shade and a Patagonia logo in a top right corner

Using infinoted

https://www.mankier.com/1/infinoted-0.7 man page
http://techmonks.net/working-together-on-text-and-source-code-with-gobby-and-infinoted/ tutorial

Setup a Gobby server
1. install infinoted
2. create the file /etc/xdg/infinoted.conf and add the following settings:

[infinoted]
security-policy=require-tls
certificate-file=/etc/xdg/infinoted.cert
key-file=/etc/xdg/infinoted.key
password=YOURPASSWORDHERE
autosave-interval=5
root-directory=/var/data/gobby/data
sync-directory=/var/data/gobby/export
sync-interval=120

3. run infinoted with --create-certificate --create-key to generate the certificate and key ($ infinoted --create-certificate --create-key)
4. start infinoted on every restart of the server. Edit the file /etc/rc.local and add this:

# starts up infinoted (gobby server)
# configuration file is in /etc/xdg/infinoted.conf
infinoted &

5. restart the server

# Browser based & peer-to-peer

## Conclave
https://conclave-team.github.io/conclave-site/
"A private and secure real-time collaborative text editor"
"a peer-to-peer, real-time, collaborative text editor built from scratch in JavaScript."
Great documentation about Conflict-Free Replicated Data Type (CRDT) and their peer-to-peer architecture!

>>> not maintained anymore

## IPFS & pubsub 
Pubsub is a decentralized "pattern" (this is how they call it) that can be used for 
	collaborative writing
	chat
	multiplayer games
	constantly evolving datasets
	webservice workers passing around messages
	> from https://blog.ipfs.io/25-pubsub/
	
>>> tiny note: have tried it and it is not ideal, but it is interesting in terms of streaming text without any authorship indication

Their next blogpost: "Decentralized Real-Time Collaborative Documents - Conflict-free editing in the browser using js-ipfs and CRDTs"
https://blog.ipfs.io/30-js-ipfs-crdts.md
"In this 10-minute video [https://www.youtube.com/watch?v=-kdx8rJd8rQ] I show you how we can use the js-ipfs library and conflict-free replicated data types (CRDTs) to build a simple text editor that allows several peers to collaborate in real-time. The resulting interactions between the nodes are conflict-free, support offline use, and allow nodes to come in and out of the network while continuously converging data to a single state in all the nodes."

PubSub
pubsub = publish & subscribe pattern 
https://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern
"This pattern provides greater network scalabilityanda more dynamic network topology, with a resulting decreased flexibility to modify the publisher and the structure of the published data."

## Dat multiwriter
https://blog.datproject.org/2018/05/14/dat-shopping-list/
a first step, but in order to sync with other writers through the browser, the application needs to connect to a node.js server elsewhere (called the gateway).

# Browser based & single server 

## Etherpad lite
"In 2009, Google started beta testing Google Wave, a real-time collaboration environment which Google hoped would eventually displace email and instant messaging.[citation needed] EtherPad was acquired by Google, which allocated the EtherPad team to work within the Wave project. However, Google announced in August 2010 on its blog[7] that it had decided to stop developing Wave as a standalone project, due to insufficient user adoption. After Google released the abandoned EtherPad source code as open source in December 2009, the community took over its development and produced a complete rewrite named Etherpad lite, which is written entirely in JavaScript and built on top of node.js." https://en.wikipedia.org/wiki/Collaborative_real-time_editor

"PeerPad is a decentralized editor that allows concurrent writing of text. Besides making live changes to a given document, it allows read-only nodes to follow the changes in real-time. It also allows you to publish a self-contained snapshot of the document to IPFS."

# Document-based collaborative editing?
The examples are pretty interesting. Specially the offline writing and online syncing combination is a promising feature...

But all the text stays in the browser? It would be great to store local copies of the text directly, preferrably as files.

Plus, the NodeJS javascript heaviness is not so attractive.

Is there software that works p2p, allows for discovery in your current local network, and saves local copies of the document as (plain) text documents?
