🔗Dept of Status of Matrix 🌡️

🔗Element Home

Element announced Element Home, a new way to get your own homeserver. Read more about it on their blog, or watch Matrix Live for a real demo.

🔗Dept of Spec 📜

🔗Spec

anoa said:

Here's your weekly spec update! The heart of Matrix is the specification - and this is modified by Matrix Spec Change (MSC) proposals. Learn more about how the process works at https://matrix.org/docs/spec/proposals.

🔗MSC Status

Merged MSCs:

• MSC2998: Room Version 7

MSCs in Final Comment Period:

• No MSCs are in FCP.

New MSCs:

• [MSC3038] Typed typing notifications

🔗Spec Core Team

This week the Spec Core Team worked on MSC2858 (sso ID providers), MSC2403 (knocking) and MSC2746 (voip signalling), as well as held another retrospective of the past month. Discussion mainly focused on process and the new spec redesign. Speaking of which...

🔗New Spec Platform

The new spec has launched! 🎉 Check it out at https://spec.matrix.org/unstable! Release versions will be landing sometime soon. Bear with us as we finalise the new release process.

Huge thanks to wbamberg for working hard on bringing the idea to a reality. The Matrix.org foundation will continue maintenance of the platform and continue to make it even better for developers in the coming months.

We've already got a number of bug reports that need fixing. If you find anything that's a bit off with the redesign, please file an issue at https://github.com/matrix-org/matrix-doc. Thanks!

Thanks to Famedly and everyone who supports me on Liberapay or Bitcoin!

🔗matrix-media-repo

matrix-media-repo is a highly customizable multi-domain media repository for Matrix

TravisR told us:

v1.2.3 is out now with a highish priority fix if you have audio thumbnails enabled. Other goodies include an X-Robots-Tag header and some artifact repairs on gif and apng thumbnails. See https://github.com/turt2live/matrix-media-repo/releases/tag/v1.2.3 for the full changelog.

🔗Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander said:

Earlier this week we released Dendrite 0.3.11, and since then we have merged a significant number of appservice fixes to master which will go into the next release. With these, bridges should stand a much better chance of working with Dendrite.

Changes include:

• Events are now properly sent to interested appservices

• Appservice namespace exclusivity is now respected properly

• Users starting with _ can now be registered by appservices correctly

• Room alias queries for appservices have been improved and should work now

We also upgraded a number of dependencies.

Spec compliance has improved slightly:

• Client-server APIs: 60%, up from 56% last week

• Server-server APIs: 82%, up from 80% last week

As always, please feel free to join us in #dendrite:matrix.org for general Dendrite chat, and #dendrite-dev:matrix.org if you are interested in contributing!

Spec compliance is really progressing!

🔗Synapse

Synapse is a popular homeserver written in Python.

callahad told us:

We've heard some feedback that Synapse's release cadence—an RC every other week, with releases in between—can feel a bit overwhelming. In response, I'm going to try to write a little less about each RC and instead simply refer to the 1.29.0rc1 Release Notes from yesterday.

We'll shout a bit more when that matures into a formal release early next week. 🙂

On non-release weeks I'll try to spend a little more time focusing on the behind-the-scenes aspects of developing Synapse in our TWiM updates. If there's anything in particular you'd like hear about, let me know!

Speaking of, we're experimenting with using GitHub Discussions for... discussions.

We don't want to go full-on mailing list, but it might be nice to have a place to for slower, asynchronous conversations that don't quite fit into the more rapid pace of a typical Matrix room.

Our first two discussion topics ask about:

• Your experiences with GitHub Discussions

• How Synapse could be better

Please do weigh in!

🔗Dept of Bridges 🌉

🔗GroupMe bridge (matrix-groupme-go)

karmanyaahm offered:

I'm working on a GroupMe bridge I made based on tulir's mautrix-whatsapp and mautrix-go.

I aim to add features like double puppeting, end to bridge encryption, etc over time, but an alpha release is available now. I would love to get bug reports and testing info to fix them.

If anyone's running/testing this please join #groupme-go-bridge:malhotra.cc to chat about it

https://github.com/karmanyaahm/matrix-groupme-go

Another recent GroupMe bridge effort: https://gitlab.com/robintown/mx-puppet-groupme

🔗matrix-appservice-bridge v2.6.0-rc1

Half-Shot announced:

A PSA this time around. Please test this release and update as soon as you can when we go to release on Monday next week. We've included a change to correct how users are registered against the homeserver to comply with the spec (Synapse accepts a /register call without a type=m.login.application, and versions 2.5.0 and below of the matrix-appservice-bridge sent these invalid requests). I'm hoping to eventually retire this behaviour from Synapse, so the more people that upgrade the better!

Also this PR is the Synapse-side change to remove this behaviour. If your appservice implementation uses this behaviour, please chime in.

🔗matrix-appservice-irc hits v0.25.0(-rc1)

Half-Shot told us:

Hey folks, this release contains a bunch of tiny-but-useful bugfixes that you'd hate to miss out on. The full release comes next week but if you want to help us test early, come and get it while it's hot! This release includes the all important fixes from matrix-appservice-bridge v2.6.0-rc1 which fix a spec compliance issue.

🔗Dept of Clients 📱

🔗Hydrogen

A minimal Matrix chat client, focused on performance, offline functionality, and broad browser support. https://github.com/vector-im/hydrogen-web/

🔗Element Web on IPFS

TR_SLimey reported:

I mentioned a while back that I've put Element Web on IPFS.

Since then, I unfortunately had to change its DNSLink domain, so I decided to post about it again, with the new addresses and some minor updates. Here are the former:

• ipns://element-web.0x1a8510f2.space/ (Main DNSLink address)

• ipns://k2k4r8mx8muu913j5oy3e4zvt77xtks8xgxuamlv0ltzwx95lcgk2glw (IPNS hash which the above address points to)

• ipfs://bafybeievxs6qzzbfbn6xcbz3xwxhjzxkffjbpwbcc3gikrac6ytqkkutva (IPFS hash of the current snapshot of the above)

In other news, I've updated Element on IPFS to v1.7.22 and made a tiny script to easily update it in future. In case it's of use to anyone, it's right here:

#!/bin/bash

if [ "$#" -ne 2 ]; then

        echo -e "Invalid number of arguments (got $# but 2 required)!\nUsage: $0 <element web folder> <release tag to download>" >&2
        exit 1

fi

wget -c "https://github.com/vector-im/element-web/releases/download/$2/element-$2.tar.gz" -O - | tar --overwrite --strip-components=1 -xzv -C $1 element-$2

ipfs add -r -p $1

echo "Now use: 'ipfs name publish -key=<publish key> <folder ID>' to publish on IPFS"

🔗NeoChat

Carl Schwan announced:

We are currently refactoring the NeoChat room page. Nothing merged yet but scrolling is now smoother, we added swipe gestures to reply on mobile, and more importantly chat bubbles are coming :) Here is a small video of the new timeline, feedback very much welcome.

🔗Dept of SDKs and Frameworks 🧰

🔗libkazv (and the Kazv Project)

libkazv is a sans-io C++ (gnu++17) client library

tusooa reported:

libkazv is a sans-io C++ (gnu++17) client library

built upon lager. Along with it there is kazv, a kirigami/qml client, and a

forward bot between matrix and tencent qq. Talk to us on #kazv:tusooa.xyz .

🔗Updates

In the past 1 week we ("tusooa and her longcat," we hope someday we can

remove this annotation :P):

1. Published API documentation on the web.

2. Together with that, added a "getting started" guide with an example >w<

3. Made matrix-tencent-forward-bot support directly forwarding images

   from the matrix room.

4. Colourized sender nicks in messages for matrix-tencent-forward-bot.

🔗Dept of Services 🚀

🔗#matrix-admins-edu-german:matrix.org

Marcus Schopen (the fellow with the festive mugs) reported:

Together with Anthony Rhode from Element we have published the room #matrix-admins-edu-german:matrix.org for Matrix Admins at German-speaking educational institutions. Here we want to discuss topics about Matrix in an academic context. The room is open to the public and everyone is very welcome.

How is it not #matrix-admins-edu-deutsche:matrix.org!? This is a welcome public room for the growing number of Matrix Admins in Germany!

🔗Dept of Interesting Projects 🛰️

🔗Cactus Comments

carl announced:

I am very excited to launch Cactus Comments (https://cactus.chat) today together with @asbjorn:olli.ng!

Cactus Comments is a federated, web-embeddable comment system. And of course, we federate by building on Matrix!

On the frontend - your website - we embed a Matrix client written in Elm that renders Matrix rooms as comment sections. The client is designed to be especially easy to embed on static sites. Once you log in to the client, it will only communicate directly with your Matrix server of choice.

On the backend, an application service is used to create rooms on-demand and help with moderation. It is built with Python and is completely stateless. It does this by modelling all state in native Matrix objects without any custom events!

The entire thing is free and open source software and we would love it if you were to contribute. We really hope some of you will give it a try!

Join our matrix room: #cactus:cactus.chat

Read the introductory blog post: https://cactus.chat/blog/hello-cactus-comments/ Try the demo: https://cactus.chat/demo/

Source code: https://gitlab.com/cactus-comments

What a project! Let's see how we can integrate this with the Matrix.org blog!

🔗Matrix Queue Processor

reivilibre reported:

With things on the Internet vanishing, I've been wanting to start saving copies of interesting web pages and videos to my server-at-home.

This really doesn't involve much more than just running youtube-dl or archivebox on the relevant URLs, but I needed a better way than having to e-mail myself reminders to download things…

I decided to make Matrix Queue Processor.

You can run it occasionally (or set it up to run in a cron job!) and it will then read all outstanding messages and feed the text to a given command, such as youtube-dl.

You can choose for it to delete processed messages, or tick them off (✅). If the command wasn't successful, it will instead reply with the exit code.

It's not particularly sophisticated but it might at least be a small starting point for anyone who wanted to make something similar, and it is end-to-end encryption capable because it uses the Python matrix-nio SDK.

See this example of use with youtube-dl; it fails on the second message because it's not a video page URL:

I like this a lot - there are so many uses for this project.

🔗Hummingbard
