Demokratis.ch is a non-profit project working to modernise the consultation procedure—a key democratic process that allows Swiss citizens to provide feedback on proposed laws and amendments. Today, the process is slow and cumbersome for everyone involved: it requires studying lengthy PDFs, writing formal letters, and even synthesising legal arguments by copy-pasting into Excel. There’s a huge oppo...

Our Lightning Talks are open to everyone 😊 about this event: https://talks.python-summit.ch/sps25/talk/EP7BNX/

Over the years, the lack of an array data type in Python has resulted in the creation of numerous array libraries, each specializing in unique niches but still having some interoperability between each other. NumPy has become the de facto array library of Python, and the other array libraries try to keep their API close to that of NumPy. However, this often becomes infeasible, and the libraries de...

Open Source has never been easy, but doing Open Source in the Matrix ecosystem poses a unique set of challenges. Add the pressure of sustaining a company on top of that, and you quickly find yourself in uncharted, and often uncomfortable, territory. This talk reflects on the reality of maintaining open source projects in the Matrix universe, especially from the perspective of a business. It dives...

It has been known since the 70s that developers tend to give very optimistic estimations. We prefer to have exact numbers, even if that means they are wrong most of the time. In research, developers admitted that they believe their managers will see them as less competent if they provide estimates with huge margins. But mathematically speaking providing a wider min-max interval means you will be r...

See a demo of E2EE encrypted DMs in Bluesky powered by Matrix. We will highlight the simple user experience and other advantages of this approach to adding E2EE to Bluesky. By reusing Matrix for E2EE DMs in Bluesky, we not only offer a trusted and tested open source encryption stack but also allow users to later expand their usage beyond chat to other Matrix features such as E2EE voice, video and...

With *Beyond Instant Messaging: Matrix in the Public Sector* last year, we presented FITKO and the German Federal Ministry of the Interior joining efforts to pilot a Matrix-based next-generation communication infrastructure for digital government services, with the goal to showcase end-to-end encryption, great usability and machine-readable communication between citizens and public authorities. Le...

Can Matrix compete with Big Tech? That remains an open question - but the market conditions in Europe have never been more favorable to sovereign, European software solutions. So how do we build commercially sound companies based on Matrix? This talk will focus on real-world use cases, showcase features built for public-sector customers, explore viable business models, and share hard-earned lesson...

The BundesMessenger is the soverein communication solution for the German government and armed forces. Developed to be robust, secure and interconnected it serves as the basis for collaboration in the public sector. With a sharp focus on user experience, an uncompromised commitment to free and open-source software and state-of-the-art deployment of cloud technologies, it brings a high-quality mess...

In this talk we will introduce Synapse Pro, the Matrix server for professional environments from Element. Synapse Pro is built to support professional Matrix deployments in terms of scalability, efficiency and high availability. It comes in two flavours, Synapse Pro for Small Hosts and Synapse Pro for Large Hosts. The Small Hosts solution introduces multi-tenancy capabilities in order to host plen...

In many parts of the world, especially across Africa, software cannot assume a stable internet connection. From rural communities to field agents working in transit or enforcement, the reality is simple: offline is the default, and sync is a luxury. In this talk, we’ll explore how to build offline-first applications using Python — apps that work gracefully when the network doesn’t. Drawing from re...

On July 15, 2025, Germany’s statutory health insurance funds will introduce the Matrix-based instant messaging service TI-M (Telematikinfrastruktur Messenger) into their electronic patient record (ePA) apps. This marks a significant milestone, as Matrix-based messengers will become potentially available to 74 million insured individuals across Germany. This talk will provide an overview of the nat...

Element Call, the flagship MatrixRTC application by Element, is shaping the future of secure, federated calling. As the successor to the traditional call system in Element apps, it now powers large-scale, end-to-end encrypted (E2EE) group calls with improved reliability and seamless federation support. This talk follows up on last year’s introduction of Element Call, showcasing a year of rapid inn...

Are you writing nested loops when solving coding challenges? Discover how Python's functional programming toolbox can transform your problem-solving approach. We'll explore functional programming principles through the lens of Advent of Code puzzles, learning to think in streams of data rather than step-by-step instructions. We’ll explore some essential bits from `itertools`, `functools`, and `ope...

Nobody likes fax machines, yet everyone still uses them – that's the reality in German hospitals. Since 2019, Famedly has been challenging this status quo. With our TI Messenger, built on the Matrix protocol, we've created a secure and decentralized alternative. Learn how we're using and extending Matrix to modernize communication in the German healthcare system. Licensed to the public under https...

Looking for more resilience and sovereignty, the European Commission has been running a trial Matrix deployment. This talk will present some of the work done.

Our project's main goal was to fill a gap by developing a telephony bridge that natively integrates XiVO enterprise telephony (based on SIP) within the alternative and open-source Matrix/Element ecosystem. Our focus with this bridge is to offer a credible and high-performing alternative to dominant proprietary solutions, such as Teams and its "Telephony System" licenses. XiVO SIP bridge project pr...

European healthcare communication is at a turning point. Fragmented national systems are reaching their limits, while the need for interoperable, secure, and user-friendly digital spaces across borders continues to grow. This talk explores how the open-source Matrix protocol has become a strategic foundation for secure messaging in healthcare — powering derived solutions like TI Messenger and CGM...

The German public administration aims to consolidate its disparate solutions for G2C and G2B communications and transition to a unified yet decentralized Matrix-based infrastructure. In this talk we will dive into this new federal infrastructure’s target architecture and explore its key requirements, drivers and architecture decisions – including the crucial choice of Matrix as the E2EE communicat...

Last year, we introduced NeoToolSuite, Nordeck’s productivity suite of Matrix widgets designed for efficient collaboration and communication. This year, our focus shifts to our flagship product: NeoBoard Standalone. This real-time collaborative whiteboard matrix client has evolved through continuous development and iteration and now it features an immersive infinite canvas that redefines what’s po...

Why should you, as a Python developer, learn Rust? In this talk, we will explore Rust's compelling answers to this question. Rust offers guaranteed type safety and memory safety without a garbage collector, "fearless concurrency", and incredible performance. We will look into some of Rust's most distinctive features from a Python perspective, including its strict compiler, the ownership and borrow...
