💬 Matrix and XMPP: Thoughts on Improving Messaging Protocols – Part 1

｢ If the Matrix network were to scale massively, with many nodes and conversations, it would encounter the same growth challenges as blockchain protocols. Each node must store a copy of the conversation, and the amount of replication depends on the number of conversations and nodes globally. As these numbers grow, so does the replication factor ｣

Are you interested in and posting on topics like: #Messaging, #MQTT, #IoT, #OpenSource, #DistSys, #Erlang, OSS business models or anything related?
Let us know by Like of Repost... We want to follow you! :) :vernemq:

Just discovered Radicle (https://radicle.xyz/), which is a peer-to-peer git forge. It has its own custom gossip protocol to propagate repo changes through the different instances.

Even if i LOVE gossip protocols, I'm still a little bit confused about all of these "distributed" forges, mainly because git is already distributed by default (https://git-scm.com/about/distributed).

Radicle authors are answering this question in their FAQ (https://radicle.xyz/faq):

```
While Git is designed in some way for peer-to-peer interactions, there is no deployment of it that works that way. All deployments use the client-server model because Git lacks functionality to be deployed as-is in a peer-to-peer network.

For one, it has no way of verifying that the repository you downloaded after a git clone is the one you asked for, which means you need to clone from a trusted source (ie. a known server). This isn’t compatible with peer-to-peer in any useful way.

Radicle solves this by assigning stable identities to repositories that can be verified locally, allowing repositories to be served by untrusted parties.
```

I'm still not convinced though, I think it's adding lots of complexity to an already complex system.

Just came across Epoxy, a protocol that aims to allow transactions between different datastores. I haven't read the paper yet (but I will), as these are some serious allegations :D

Are you interested in messaging, message brokers, #MQTT, #IoT and #DistSys (distributed systems) in general?
Like or re-post to let us know... we want to connect and learn from you! :) :vernemq:

hello fedimortals, what are the most beautiful computer things to you — whether in the realm of #software, #hardware, #networks, #distsys, etc.?

what pleases your aesthetic senses? what feels poetic? what fills you with awe, wonder, or excitement?

serious answers preferred 🖤

Sometimes, the devil's lies in the details. Having a #distsys capable of diagnosis itself is such a relieve 🤩

Thanks #FoundationDB

#MQTT never was a specification for distributed messaging. Its origins date back to when a server was one server with one CPU. Modern brokers like VerneMQ offer distributed messaging, but there are always #Distsys decisions & tradeoffs.
A fascinating topic to us! :)

I got nerdsniped by @tef & @sushee to demonstrate how relatively easy it is to build a CRAQ (https://timilearning.com/posts/mit-6.824/lecture-9-craq/) system atop @couchdb — Showing that as much as CouchDB is a distributed database in itself, it is also a very nice toolkit to build other kinds of distributed databases with it :)

The demo is in Node.js with some private JS/HTTP API glue that is not relevant to the demo: https://gist.github.com/janl/d0ba3544631e054e59fbd5f4d3ee96f8

Let me know if you ahave any questions.

I just published https://github.com/lant/maelstrom-java in the central maven repository.

This project is a simple java wrapper over the Maelstrom distributed system workbench. (https://github.com/jepsen-io/maelstrom)

If you want to play with Maelstrom using JVM languages, this library will hopefully take away the pain of writing tons of boilerplate.

paging @muratdemirbas an intertwined bunch of different musical, art, and philosophical references, to then go deep on #distSys ;) original !!!

I just completed challenge 3 (a-e) and I've got some nice code that works but I'm not happy with it. I'm also not happy with the grading mechanism being number of messages not size of messages. I feel like I've cheated.

The challenge is to keep X number of nodes in sync with these numeric broadcast messages that go to random nodes, so it with network partitions and do it without flooding your network. Eventual consistency.

Next week is the February 2022 edition of Fission's #distsys reading group hosted by @expede.

The paper being reviewed is "Metastable Failures in Distributed Systems”, presented at Hot Topics in Operating Systems (HotOS ’21) last year.
