Matrix Live 🎙

Dept of Status of Matrix 🌡

Last week Matrix had a presence at UbuCon Europe and PyCon Ireland. We gave workshops on using Matrix to create bots, and also a session on installing Synapse (see also: Brendan's entry below!)

Hey #PyConIE! We hope you enjoyed the Matrix workshop, find the slides and code samples at https://t.co/aT1dDuEcm1 and make sure to ask any more questions! pic.twitter.com/C2qwV5R3gl

Tomorrow I'm off to sunny Manchester with Michael from the Ops team. We'll visit OggCamp, where we'll show off Matrix with a fun demo I previewed on Matrix Live a few weeks ago.

Matrix will ALSO be at:

• Re­decentra­lize Conference 2019
• MozFest 2019

Dept of Spec 📜

anoa:

Last week we set MSC1219 (key backups), MSC2241 (verification over DMs), and MSC2313 (ban lists) for the spec core team to focus on. Those 3 are rolling on into this week as we didn't get a lot of work done last week :)

In other Spec news, Matthew uncovered a stone tablet describing what would in future be known as "MSC2324":

install-party, nice result from UbuCon Europe

Brendan said:

For a workshop anoa and I did at Ubucon Europe last Sunday on how to install Synapse, I worked on a side project that creates a server, attaches a domain name to it and installs Riot and Caddy on it. Attendees can then SSH into it, follow the instructions to install a Matrix homeserver, and use Riot to register an account on it, log in, and join a federated room with all of the other attendees' homeservers in it. We tried it out last week-end for the actual workshop and it worked quite well 🙂 The project is called Install Party, and lives at https://github.com/babolivier/install-party, and if you want to chat about it I've just created #install-party:abolivier.bzh 😉

Synapse

Neil reported:

This week we've been thinking about the future and brainstorming on ideas to improve perf for small instances and sparing some cycles for MSC1228. Next week we'll return to improving IO usage on matrix.org.

Synapse 1.4.1 was released, which fixes a small regression in 1.4.0.

Dept of SDKs and Frameworks 🧰

matrix-3ds-sdk

sorunome said:

Heya, matrix-3ds-sdk is a new matrix sdk - for the Nintendo 3DS! It is still deep in development, so expect bugs, some things not working properly etc. Current features include:

• logging in
• sending text messages to rooms
• redacting events from rooms
• resolving aliases to room ids
• basic framework to get a /sync loop working

If you are into 3DS homebrew development or are interested in helping out making a full client based on this, please contact soru (@sorunome:sorunome.de)! 3ds homebrew dev is pretty new to her, so there are plenty of open questions / debugging help would be great!

Support room: #matrix-3ds-sdk:sorunome.de Donate: https://liberapay.com/Sorunome

This is really impressive, I'm looking forward to playing with it. (I'm sure someone at the office must own a 3DS!)

I'm building the Synapse 1.4.1 multi-arch docker image. It will be pushed to Docker Hub in a couple of hours.

Dept of Tulir 🇫🇮

A special section this week from the guy with one editor open for everything, tulir:

I haven't done anything on my own projects this week, but I did contribute to a bunch of other projects:

• Updated SmsMatrix to the latest matrix-android-sdk to fix outgoing sms duplication bug (https://github.com/tijder/SmsMatrix/pull/60)
• Fixed Riot web sending reply fallbacks in edited message content (https://github.com/matrix-org/matrix-react-sdk/pull/3551)
• Fixed some things in the Riot web edit html -> markdown parsing (https://github.com/matrix-org/matrix-react-sdk/pull/3552)
• Made Riot web reply rendering much nicer and more compact (https://github.com/matrix-org/matrix-react-sdk/pull/3553)
• Added full emoji picker for reactions to Riot web (https://github.com/matrix-org/matrix-react-sdk/pull/3554)

The first two are already merged (and SmsMatrix even got a new release on f-droid), the html parsing is waiting for code review and the emoji picker and reply rendering are waiting for design review.

Also, I made a read-only status.matrix.org rss feed room since some people wanted one: #matrix.org-status:maunium.net. I don't remember if I TWIMed these before, but #xkcd:maunium.net and #commitstrip:maunium.net are similar read-only rooms, new xkcds and commitstrips are posted there whenever they come out.

That's all I know 🏁

See you next week, and be sure to stop by #twim:matrix.org with your updates!

Hi all,

We've released Synapse 1.4.1 as a small but important bugfix to 1.4.0.

This fixes a regression which crept in with our newly implemented "erase redacted data after N days" feature where some APIs would fail when hitting erased redactions - anyone on Synapse 1.4.0 will want to upgrade asap.

As always, you can get the new update here or any of the sources mentioned at https://github.com/matrix-org/synapse. Also, check out our Synapse installation guide page

The changelog since 1.4.0 follows:

Synapse 1.4.1 (2019-10-18)

No changes since 1.4.1rc1.

Synapse 1.4.1rc1 (2019-10-17)

Bugfixes

• Fix bug where redacted events were sometimes incorrectly censored in the database, breaking APIs that attempted to fetch such events. (#6185, 5b0e9948)

Dept of Servers 🏢

Synapse

Neil told us:

Matrix.org hit some IO problems earlier this week, while largely a problem with our hosting provider, we’re spending a bit of time to make Synapse more resilient if the same thing were to happen again. This will mean the ability to shard the DB (by table) and spread the load so we are not so dependent on high performance from a given db box. Outside of that we’ve been working on the final polishing of the room directory and getting the sqlite -> Postgres port script into better shape.

multi-arch docker image of Synapse

Black Hat said:

My multi-arch docker image of Synapse has been updated to v1.4.0.

That's all I know 🏁

See you next week, and be sure to stop by #twim:matrix.org with your updates!

Hi all,

Massive news for the Matrix ecosystem today: New Vector (the startup which the Matrix core team formed to fund development in 2017) has raised an additional $8.5M of funding in order to speed up Riot/Matrix development and expand Matrix hosting via Modular.im!

The new funding comes in the form of a Series-A equity investment in New Vector from three of the top venture capital funds in London. The round is led by Notion - a fund set up by the founders of MessageLabs, who many will know as one of the leaders in secure hosted email services. Notion's long history with email means they immediately clocked the potential of Matrix's mission to build a new open global communication network - after all, Matrix aims to provide a worthy replacement to email (and the phone network, for that matter!). Joining Notion in the round is First Minute - a fund set up by the founders of Lastminute.com (arguably the UK's most famous original dotcom), and Dawn - one of the largest SaaS tech specialist funds in Europe (famous for backing iZettle, Mimecast, Neo4J and many more).

The last funding round in Jan 2017 from Status was instrumental in stabilising the big 1.0 release of Matrix and exiting beta in June; creating the Matrix.org Foundation as a neutral custodian for the standard; stabilising and optimising Synapse; redesigning Riot’s user interface; bringing in a full-time professional UI/UX designer to the team; supporting the huge amount of encryption work required to turn on E2EE by default (cross-signing, key backups, device verification, e2e search, the pantalaimon e2e daemon etc); creating RiotX/Android; and launching the Modular.im hosting platform.

With today’s new funding, the priorities for Matrix will be:

• Turning on end-to-end encryption by default for DMs

• Much better support for grouping rooms into Communities

• More anti-abuse/anti-spam mechanisms

• Shrinking Synapse (and/or finishing Dendrite)

• Canonical DMs (having one DM per user, and have them feel clearly distinct from ‘rooms’)

• Extensible Profiles

• Decentralised accounts

• Threading

• ...and furthering development on P2P Matrix, so users can have full control of their communications without having to run or trust a server.

On the New Vector side, this funding will support:

• A whole new wave of UX improvements to Riot (particularly around onboarding and first time user experience).

• Making Modular hosting as polished and powerful as possible.

• Creating a whole new set of next-generation Modular integrations.

While New Vector’s contributions to the Matrix ecosystem can’t be ignored, it’s important to remember that the Matrix protocol and specification itself is governed and controlled by the independent and neutral Matrix.org Foundation and its extensive governance processes. We set up the Foundation very deliberately to enforce the protocol's neutrality, formalise the project's mission, goals and values and hold true to them no matter what - specifically to protect the project from conflicts of interest with commercial Matrix endeavours, including New Vector.

That said, New Vector would not be taking money from any investors if they did not believe their goals are aligned with Matrix's. To clarify:

• Matrix exists to create an open secure decentralised communication network and protocol for the benefit of all.
• New Vector exists to help grow Matrix and be one of many successful companies in the Matrix ecosystem.
• Tech VCs exist to invest their money in growing companies in order to get a return when the company IPOs or gets bought.

It turns out that these goals are not incompatible if one understands that the potential of the Matrix ecosystem is directly linked to its openness and size (hint: funding sources who didn’t understand this self-selected out ;). By funding Matrix development and helping the open ecosystem and public network grow, New Vector can go provide more Matrix hosting via Modular.im and more Government & Enterprise deployments via Vector.im. Critically, other companies can and do build on top of Matrix too - and frankly the more players there are, the more valuable the network, and the more value to be shared for everyone (including New Vector). This model worked relatively well for the Web, and we believe it'll work for Matrix too.

Update: the best way to gauge the investment in New Vector is to hear it first hand from the investors. Jos from Notion is leading the round, and has a fascinating blog post (written with zero input from Matrix or New Vector folks) to explain where the investors are coming from.

Update 2: More excellend first-hand analysis from Dan at Dawn Capital, who does a really deep dive into how they see Matrix and New Vector. Another must read.

In this case, all of New Vector's new investors have a background as respected tech entrepreneurs, and everyone involved categorically understands that Matrix itself is a neutral open source project, and the mission is to help build up the whole network to be as successful as possible rather than sabotage it by constraining it in any way.

All in all, it’s great news for the ecosystem: Matrix is 5 years old now, and while the project is growing faster than ever (over 300% more active users in the last year!) - it's fair to say that we haven't moved as fast as our mainstream competition - for instance, Slack is only a year older, and Discord is a year younger(!) Obviously much of this is due to Matrix being a completely different proposition: we've been creating an open spec; multiple client codebases; multiple server codebases; the bridges; a fault tolerant decentralised network - not to mention the complexities of decentralised E2E encryption. Based on comparing with our endeavours prior to Matrix, we estimate building this stuff in an open and decentralised manner takes roughly 6 times longer.

But the project is now in a position where the foundations are solid: the protocol is out of beta, reference servers and clients are production ready, and it’s more than time to make all of this mainstream. We have to redouble our focus on user experience and ensure that we compare favourably to today’s established alternatives while staying true to Matrix’s principles. Making sure there are Matrix apps out there which provide a credible alternative to with the likes of Slack and WhatsApp (until they eventually join Matrix, of course) is what will make the difference between Matrix being a cliquey FOSS curiosity versus really being the natural successor to today’s instant messaging, email and phone networks.

In the end; Matrix needs full-time contributors in order to continue to grow, and keeping New Vector funded is a very good way to achieve that (New Vector is hiring!). (That said, if any philanthropic billionaires are reading this, the Matrix.org Foundation is actively soliciting donations to improve Matrix independently of New Vector's efforts - particularly around the areas of countering online abuse and disinformation).

In the meantime, huge thanks to Jos at Notion for believing in Matrix and leading this funding round in New Vector - and huge thanks to the other investors who saw the potential! And most of all, thank you to all those supporting Matrix, whether by donating to the Foundation, promoting and using the protocol, or contributing code to the ecosystem. You are the ones keeping the dream alive :)

You can read things from the NV angle over at https://blog.vector.im/8-5m-to-accelerate-matrix/. We hope you’re as excited as we are to open a whole new chapter as Matrix picks up yet more momentum :D

Two MSCs have reached final comment period this week:

• MSC 2176: Update the redaction rules
• MSC 2290: Separate Endpoints for Threepid Binding

Last week the spec core team said they'd start focusing on 3 MSCs per week. Those were MSC2290, MSC2176 and MSC1219. The first two have entered FCP, and MSC1219 will roll over into this week.

Thus, the 3 MSCs the spec core team will be focusing on this week will be MSC2199, MSC1219 and an up and coming security-related MSC. Join us in #matrix-spec:matrix.org for related spec discussions :)

There is also a new MSC, MSC2312 describing the proposed Matrix URI scheme. This is a remake of a much older proposal. The general idea is to make a standard for Matrix URIs: matrix:.

Synapse 1.4.0 released

Neil offered:

Synapse This week we shipped our privacy release 1.4.0 which is a huge deal in improving user data privacy. Additionally we also included a significant perf improvement which will help anyone suffering from a build up in forward extremities.

Coming up, improved room directory perf, ironing out wrinkles in the room upgrade UX as well as a major reliability boost in the sqlite -> Postgres db porting script.

Dendrite dev recommences

anoa said:

Dendrite's latest hiatus has come to a close after the privacy work had taken so much of my time. Thankfully although PR review is blocked on the dendrite team, the community have continued to submit PRs and even review each other's PRs (thanks cnly !).

Fixes this week have mostly focused around the CI. We finally got Dendrite's CI unborked (t'was borked in a half-way transition between CircleCI and Buildkite), but it's now working and faster than ever. We're also working to add the Sytest test failure results to the top of the CI window such that people can see which tests failed and the associated Dendrite logs.

Additionally we had some new and merged PRs this week! A federation fix from cnly, a change to allow Dendrite to better work in kubernetes setups by aditsachde, and a codebase fix from @manasseh:matrix.org, who's also working on another fix involving updating gomatrixserverlib to support more recent spec versions.

Some things people were asking about:

• Progress of dendrite is tracked in Dendrite's milestones. We're currently aiming for #1 (Client-Side) Bot Hosting.
• CI not running for community PRs - Buildkite hosts currently run multiple PRs from many different projects, so we can't trust arbitrary code to run on them quite yet. There's a project in progress to run the code in a sandboxed environment (think VM or container) to lift this restriction :)

Final thoughts 💭

Mastodon released v3.0.0 - check it out.

That's all I know 🏁

See you next week, and be sure to stop by #twim:matrix.org with your updates!

Hello Matrix enthusiasts! Yesterday we released matrix-appservice-slack 1.0. This marks a major milestone in bridge development for the Matrix.org team, being our first bridge to ever reach 1.0. The decision to release this version came after we decided that the bridge had gained enough features and reached a point of stability where it could be deployed in the wild with minimal risk.

For those not in the know, the Slack bridge is Node.JS based, and bridges slack channels & users into Matrix seamlessly. And for those wondering, yes it works with Mattermost too (since their API is compatible with Slack)! In previous versions only a limited subset of features were supported, making heavy usage of Slack’s webhook API. As of 1.0, the bridge now makes use of the newer Slack Events/RTM API which gives us all we need for a richer bridging experience. Everything from edits and reactions to typing notifications is supported in the 1.0 release.

Finally for those who are self hosting, we are pleased to offer the ability to "puppet" your Slack account using the bridge. Puppeting is the process in which the bridge will send messages as if you were sending them from the Slack client directly, when you talk using your Matrix account. This opens the door to seamless bridging and direct messaging support.

For those wishing to bridge their whole workspace across, picard exists as a tool to manage large scale Slack bridge deployments. This tool is provided by Cadair and SolarDrew

Threading & Reactions!

The bridge has undergone some pretty serious code surgery as well. The whole codebase has been rewritten in TypeScript to take advantage of type checking and generic types. The bridge is currently based upon the matrix-appservice-bridge library. The datastore interface now supports PostgreSQL, wich allows for administrators to inspect and edit the database while the bridge is running, as well as offering helpful performance boost over the NeDB datastore format that was used previously. Finally, the codebase has proper Unit and Integration Tests to ensure new changes will not cause any regressions in behaviour. In short, now is an excellent time to get involved and hack on the bridge. There is already a crafted list of easy issues for new and experienced bridge devs.

Memory usage of the bridge comparison

CPU usage of the bridge comparison

In terms of how many users matrix.org is currently serving at the moment, we present to you some figures:

• 2562 bridged rooms
• 764 teams connected to the bridge
• 103711 events have passed through the bridge since the launch of 0.3.2

Of course, our work doesn’t stop at 1.0. The plan for the immediate future of the bridge is to continue adding support for other event types coming from Matrix and Slack to create an ever richer experience. Obvious features are things like topic changes, and syncing membership across the bridge. In the long term future we would also like to add community support to the bridge, so whole Slack workspaces can be bridged across with a single click.

That’s all from me, and I would like to say a massive thank you to Cadair and Ben for both their code and review work on the project and as always, thank you to the community for using the bridge and reporting issues. 🙂
