Matrix is an open standard for decentralized communication that allows users to communicate across multiple platforms and apps. It aims to address issues with proprietary communication apps by giving users control over their data and privacy through an open-source, federated network architecture. Key features include end-to-end encryption, flexible application services, and a client-server API that allows different apps and servers to interact on the same network. The project is seeking more participation to test servers, provide feedback, and help standardize the APIs.
SIP Express Media Server SBC application as powerful SBC and SIP toolboxstefansayer
The SIP Express Media Server, originally a media server to complement SIP based VoIP networks with services such as voicemail, conferencing and IVR services, with the introduction of a B2BUA and especially the SBC module can be useful as call stateful control element in the operator core, for specific applications, or as a full Session Border Controller. In upcoming SEMS 1.6, again a whole lot of useful functionality has been and will be added, among them registration handling, tcp stack and more NAT traversal options, transcoding, multiple interfaces, bandwidth limiting etc. Further, a new extended call control interface which even can be scripted with the super simple DSM state charts language not only supports more complex, PBX type call flows, but also makes SEMS a toolbox useful for most situation where a call stateful element is needed.
Application Visibility and Experience through Flexible NetflowCisco DevNet
The world of applications is changing rapidly in the enterprise; from the way applications are increasingly hosted in the cloud, the diverse nature of apps and to the way they are consumed by many devices. The need for organizations and network administrators is to focus on "Fast IT" - "Innovation in the Enterprise" is growing, which means having to spend less time on daily operations, maintenance and troubleshooting and more time on delivering business value with newer services. Cisco AVC with its NBAR2 technology is designed to detect applications and measure application performance through measuring round trip time, retransmission rates, jitter, delay, packet loss, MoS, URL statistics etc. Those details are transmitted using Flexible Netflow/IPFIX, so partners could leverage the data for application usage reporting, performance reporting and troubleshooting application issues to deliver best possible application experience.

"SIP 2.0 was published as an RFC in 2002 and started a revolution in the telecom industry. The big move away from traditional technologies is still happening and things are moving fast. But 99% of the implementations of SIP are still focused on ISDN-over-IP, something that is very frustrating to many that believe that there are much more functionality in SIP. WebRTC is about to become standardized and we already see some early implementations. How will this affect the SIP industry and what should be in focus for the coming year? Olle delivers his thoughts, ideas and will give some clear instructions about how to move forward."

Microservices Practitioner Summit Jan '15 - Don't Build a Distributed Monolit...Ambassador Labs
Ben Christensen of Facebook, Netflix, and author of Hystrix.
In pursuit of ease and obedience to the DRY ("don't repeat yourself") axiom, it is common to build a distributed monolith instead of the intended decoupled microservice architecture. This talk will explore the common pitfalls, the pain they cause, and approaches to connecting microservice permitting the promised separation of concerns that allows varied architectures, platforms, languages, timelines, and incremental rewrites of a microservice system.

Building an Open M2M community one step at a timeBenjamin Cabé
It is widely agreed that there will be devices in the range of billions communicating with each other by the end of this decade. From the alarm system in your house, to your power-meter being part of a smart grid, to the ATM around the corner, every object of your life will soon be connected to the Internet of Things, if not already.
This connected world is at the crossroads of various ecosystems that the Eclipse M2M Industry Working Group aims at bridging.
On one hand are the IT and telco industries, that already are connecting devices together by means of usually closed software platforms and communication protocols. These industries have an incredible experience at designing solutions tailored to their vertical businesses, but today's challenge is to break down the silos preventing the emergence of the true Internet of Things: every object should virtually be accessible from anywhere.
On the other hand, there are many providers of great end-user services that are waiting for platforms allowing them to create their own applications using these services, that they can distribute on their own markets and via social networks.
Lastly, the Open Hardware and hobbyists movements are a place where a lot of innovation happens: bleeding edge technologies, passionate developers that can, and will, make Internet of Things not only successful, but also fun.
If you want to learn what is cooking at Eclipse in terms of tools and frameworks for M2M development, how we get the aforementioned communities actively involved, and the business models that this Open M2M stack is enabling, then this talk is for you!
The presentation describes a variety of solutions in the IoT area and provides hints on creating distributed systems. It focuses on modern standards in the field of IoT, their disadvantages and prospects.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

11. Matrix is for:
Group Chat (and 1:1)
WebRTC Signalling
Bridging Comms Silos
Internet of Things Data
…and anything else which needs to
pubsub persistent data to the world.
11
21. Functional Responsibility
• Clients: Talks simple HTTP APIs to homeservers to push and
pull messages and metadata. May be as thin or thick a
client as desired.
• Homeservers: Stores all the data for a user - the history of
the rooms in which they participate; their public profile
data.
• Application Services: Optional; delivers application layer
logic on top of Matrix (Gateways, Conferencing, Archiving,
Search etc). Can actively intercept messages if required.
• Identity Servers: Trusted clique of servers (think DNS root
servers): maps 3rd party IDs to matrix IDs.
21
23. The client-server API
To send a message:
curl -XPOST -d '{"msgtype":"m.text", "body":"hello"}'
"https://alice.com:8448/_matrix/client/api/v1/rooms/ROOM_
ID/send/m.room.message?access_token=ACCESS_TOKEN"
{
"event_id": "YUwRidLecu"
}
23
24. The client-server API
To set up a WebRTC call:
curl -XPOST –d '{
"version": 0,
"call_id": "12345”,
"offer": {
"type" : "offer”,
"sdp" : "v=0rno=- 658458 2 IN IP4 127.0.0.1…"
}
}'
"https://alice.com:8448/_matrix/client/api/v1/rooms/ROOM_
ID/send/m.call.invite?access_token=ACCESS_TOKEN"
{ "event_id": "ZruiCZBu” } 24
25. The client-server API
To persist some MIDI:
curl -XPOST –d '{
"note": "71",
"velocity": 68,
"state": "on",
"channel": 1,
"midi_ts": 374023441
}'
"https://alice.com:8448/_matrix/client/api/v1/rooms/ROOM_
ID/send/org.matrix.midi?access_token=ACCESS_TOKEN"
{ "event_id": “ORzcZn2” }
25
27. Application Services (AS)
• Extensible custom application logic
• They have privileged access to the server (granted by
the admin).
• They can subscribe to wide ranges of server traffic
(e.g. events which match a range of rooms, or a range
of users)
• They can masquerade as 'virtual users'.
• They can lazy-create 'virtual rooms'
• They can receive traffic by push.
27
28. Uses for AS API
• Gateways to other comms platforms
e.g.: all of Freenode is available at #freenode_#foo:matrix.org
• Data manipulation
– Filtering
– Translation
– Indexing
– Mining
– Visualisation
– Orchestration
• Application Logic (e.g. bots, IVR services)
• …
28
29. A trivial application service
import json, requests # we will use this later
from flask import Flask, jsonify, request
app = Flask(__name__)
@app.route("/transactions/<transaction>", methods=["PUT"])
def on_receive_events(transaction):
events = request.get_json()["events"]
for event in events:
print "User: %s Room: %s" % (event["user_id"], event["room_id"])
print "Event Type: %s" % event["type"]
print "Content: %s" % event["content"]
return jsonify({})
if __name__ == "__main__":
app.run()
29
30. Matrix Bridging with ASes
Existing App
Application
Service
3rd party
Server
3rd party
Clients
31. matrix-react-sdk
• All new web client SDK!
• Sensible separation of:
– HTTP API wrapper
– Matrix client state machine
– UI business logic
– UI look & feel (skin)
• Either customise per-component
• …or fork your own skin.
31
32. End to End Encryption with Olm
• Apache License C++11 implementation of an
Axolotl-style ratchet, exposing a C API.
• Axolotl is Open Whisper System's better-than-
OTR cryptographic ratchet, as used by
TextSecure, Pond, WhatsApp etc.
• Supports encrypted asynchronous group
communication.
• 130KB x86-64 .so, or 208KB of asm.js
32
34. Group chat
• Adds a 3rd type of ratchet, used to encrypt
group messages.
• Establish 'normal' 1:1 ratchets between all
participants in order to exchange the initial
secret for the group ratchet.
• All receivers share the same group ratchet
state to decrypt the room.
34
35. Flexible privacy with Olm
• Users can configure rooms to have:
– No ratchet (i.e. no crypto)
– Full PFS ratchet
– Selective ratchet
• Deliberately re-use ratchet keys to support paginating
partial eras of history.
• Up to participants to trigger the ratchet (e.g. when a
member joins or leaves the room)
– Per-message type ratchets
35
36. Current Progress
• Funded: May 2014
• Launched alpha: Sept 2014
• Entered beta: Dec 2014
• Stable v0.9 Beta: May 2015
• Crypto & React SDK, Jul 2015
• Aug 2015: Approaching 1.0...?
36
37. What's next?
• Rolling out E2E encryption
• Multi-way VoIP
• Lots more Application Services
• Landing V2 APIs
• Use 3rd party IDs by default
• Yet more performance work
• Spec polishing
• New server implementations!
37
39. • We need people to try running their own
servers and join the federation.
• We need people to run gateways to their
