My highlights from DINAcon 2025, the annual Swiss conference for Digital Sustainability in Bern.
114 #dinacon #hacknight

DINAcon is the annual Swiss conference for Digital Sustainability ("DIgitale NAchhaltigkeit"), organized by CH Open and partners, that took place again in Bern yesterday.

DINAcon – Konferenz für digitale Nachhaltigkeit

Digital sustainability ensures that digital assets like data, software, and content bring long-term societal and ecological benefits. One of the main discussion topics of the conference, is how to ensure that digitalization not only progresses, but is also designed sustainably and accessibly. In Switzerland, this affects many areas such as digitalization policy, data protection, copyright, as well as technological developments like Open Data and the Blockchain.

We had over 270 guests from IT, communities, administration, politics, and civil society meeting at the Kongresszentrum Kreuz this year, with 36 presentations on a variety of current Open Source technologies, applications, infrastructures, and legal developments. I am very thankful to the speakers, sponsors and all the participants for a very insightful day.

A fundamental topic again in 2026 was security and data protection technologies to strengthen digital sovereignty, and one way we do this each year is with the DINAcon HACKnight - our after-hours mini-hackathon for Digital Sustainability in Practice. I covered this already back in 2017 on this blog.

Videos and slides will be available soon - I'll update this page in a few days. Here are a few highlights of the conference, which you can also see in my live blogging on Mastodon during the entire day, in a single thread.

Morning

Details on each speaker can be found in the official program (German / French).

Having a strong law in the books is one thing, consistent follow-up is another. From Bulgaria to Trinidad & Tobago, Paula Grzegorzewska from the Linux Foundation talks about going the distance with „First, recognition, next - strategy. On in European policy“. Paula referred to the EU digitalisation summit in Berlin, happening in parallel to DINAcon:

EU-Summit - Bundesministerium für Digitales und Staatsmodernisierung

During the rest of the day I followed (and tech-supported a few) sessions in the Mobility and A.I. tracks.

Lucie Pannecoucke addresses the audience with an illustration of smart train systems.

In an excellent session on Mobility Data & Services, we heard more about the potentials, role and risks of data spaces in the future of public transport. I was glad to hear about notable data accessibility and access challenges from Benno Staub, Lucie Pannecoucke, Pierrick Servais, and Marcel Rieser.

Marcel Rieser asks: which data is (yet) not Open Data? Vehicle fleets ("mobility tool ownership") are only available as highly aggregated data. The commuter matrix www.pendleratlas.ch is operated by a German company based on STATPOP. Tax departments would have this data.
Tobias Bowald from Wavestone shares "Challenges and requirements for the development and successful establishment of intermodal mobility platforms". Technical integration: Standardised APIs - Harmonised booking/Sales processes & Business logic - Availability of real-time data. Commercial & Organisational aspects: Governance & Open Data - Mandatory vs. voluntary - Business models and Profitability vs. cost distribution.

Developing mobility-as-a-service is not easy, as the many failed platforms highlighted, but having MODI as a feature makes sense for next gen apps. This was inspiration to pitch a HACKnight challenge on the topic.

"Decision on deployment" • Taking into account the future development of the number of missions • Complex geography - Long valleys - Central hospital • Optimal utilisation of the existing rescue resources to provide the best possible care for the population • Most economical use of the existingrescue resources • Aggregation of traffic and mission data to visualise the possible data in themission control system and on the rescue vehicles. • Dynamic, optimal and economical use of the rescue resources in the interests of the patients.

In a canton where an ambulance trip can last 80km in hilly terrain, the challenge of coordination is clear. A „Next Best“ real-time data system for emergency services is presented by Jakob Böttger (City of Bern, above) that dynamically combines traffic data, deployment patterns, resource availability, and medical needs to automatically select the fastest and most suitable vehicle.

Afternoon

„The community“ with a list of Resilio's project partners.

After a quick lunch break, we "Unveil the environmental impact of the ICT sector in Switzerland" – with a talk by Constant Riolo, who draws from a landmark 2024 study by Resilio - in partnership with the ITU, EPFL, Swisscom, SwissICT and many others. Recommendations include enhancement of recycling, BYOD policies, and customer awareness.

"Issues with Big Tech" • Vendor Lock-In • Espionage risk • Long term cost • Kill switch • Accounts 'owned’ by employees not company • Not Open Source • Not decentralised • Data security at risk

The convenience trap of Big Tech is eloquently discussed by Nina Müller (above) on behalf of Nextcloud. An Open by Default policy seems a no-brainer after looking at the thought points presented.

With “the Functional Framework”, like the open API registry from TM forum, companies can put consistent standards, requirements and access pathways for customers or suppliers in one place. Florian Kammermann (above) showed us in detail how this is being used by Swisscom to standardize interfaces among telcos and Service Providers. We also promoted this topic in a HACKnight challenge.

Slide from Michael's presentation, listing the various open source components: AlmaLinux, openstack, kubernetes, GitLab, OpenTofu, puppet

stepping stone provides secure, Swiss-based AI infrastructure and HPC, supporting industrial science projects with complete data sovereignty (US-hardware excepting, as an audience question pointed out) and security requirements. An excellent input from Michael Eichenberger, CEO, which dove into some of the scientific/industrial applications being developed on their open source platform. Really recommend checking out the full talk when it's available.

Inference Utility

On a topic closely related to Michael's input above, in the afternoon I replaced Patrick Hofer (who was unfortunately was out sick), to repeat a talk I gave the day before in French in Biel/Bienne. My input into the AI track covered some history, and shared an outlook for the civil sector. In particular, I discussed the movement as a way to get behind sovereign ML/AI projects, and build on the foundations of Public Money, . Specifically I discussed the work of publicai.co on the vision of a public Inference Utility, making the Apertus model available early on to non-technical users in Switzerland and other countries.

My slides - with some ideas for how to get involved - are here:

Inference Utility
Develop large language technologies in the open - as a public service tool, emphasizing sustainability, neutrality, transparency, and individual agency in using AI responsibly.

An earlier blog post on the topic of Apertus is also relevant:

Learn about my initial experiences working with the Apertus Large Language Model during the Swiss {ai} Weeks, with advice on getting started yourself.

In the final track session of the day, we heard from Matthias Günther, who gave the low-down on EMBAG Art. 9 - a law that requires the 🇨🇭Swiss federal government to publish commissioned software. This alone generates no direct benefits, he said, going through several historic and current example projects, to draw from deep experience on achieving real synergies and cost savings.

Open development must involve stakeholders from the requirements gathering phase and include collaborative development with selected third parties, requiring adapted governance structures. This was reiterated in a powerful final keynote from a legendary figure in the open source world.

What Freedoms are we losing? What do we really mean by sovereignty? What happens when we click „I agree“ and give up control of our systems? 🫣 Henry Poole showed us the blind spots, with maturity models for service firms, small businesses even, that find a sustained purpose in digital stewardship and technical ecosystems.

The Four Freedoms: The Lost Foundation - "Freedom Becomes Real at the Edge" • Four Freedoms: use, study, modify, share • Clinicians & staff improve tools locally • Agency where work happens = sovereignty • Sovereignty dies when these freedoms disappear

Join the FSF 40 Hackathon to celebrate and support four decades of free software activism this weekend! Henry Poole was joined by a brilliant panel for a closing discussion.

HENRY POOLE / RAHEL ESTERMANN / NINA MÜLLER / TOBIAS BRUNNER

Rahel Estermann (speaking above) has put in almost 40 proposals at the Lucerne parliament, several on topics of open data and software freedom. It was a great wrap to the conference with a visionary panel discussion moderated by Clarisse Schröder.

But it was not the finale - we were treated to art and music, delivered by Sophie Dietiker, a secondary school student and talented singer performing „The open world is our legacy!" – an upbeat anthem set to a GenAI soundtrack and generative video that is representative of the unbelievable times we live in.

Matthias Stürmer announcing on stage

At last we are at the end of the staged event, and it's time for the Apéro + HACKnight! But first, I need to tell you about our poster session.

Prototype Fund

Sharing the largest room of our location with stands of our sponsors, there was a showcase set up by Opendata.ch to highlight some up and coming initiatives. This lively exhibition of new ideas and innovative technologies took place in the old chapel.

Meeting such lovely people, you might quickly find yourself discussing the challenge of running AI applications on embedded hardware. Also known as 'edge' devices, Tensor Processing Unit (TPU) boards like these pack a lot of punch.

As demonstrated in the real-time computer vision applications of the WildCamera project:

You can find this project and other Round 4 teams of the Prototype Fund here:

Projekte - Runde 4 - Prototype Fund CH

A real highlight for me was getting to know the exhibitors – such as Urs & Miranda from the Zero-Power-Indicator (ZPI) - who also developed this incredibly useful device:

They have a whole bunch of other interesting hardware hacks in their shop:

GaudiShop – Open Technology

And we hacked on their documentation during the HACKnight, producing this wiki:

GaudiLabs/qPocketPCR | DeepWiki
This repository contains complete hardware design files for the qPocketPCR portable PCR (Polymerase Chain Reaction) device. The repository focuses on two key physical assemblies—the LaserLid component

HACKnight

During our traditional "apéro with keyboards", we welcome people and machines of all skill levels, inspired by open hackdays and hackergartens. On this page we post challenges, issues and activities from projects presented at DINAcon. We also provide a quick introduction to anyone interested in learning more about the activities of CH Open. All relevant proposals to start, improve or support open source projects are welcome. The entry is free, and so is the shell 🖪 and beer 🍺 thanks to all the partners and supporters of DINAcon!

During the day, we scribbled ideas and put stickers on a board next to the Prototype Fund exhibition: basically our mini-unconference. The ideas were transferred to a Dribdat site at hacknight.dinacon.ch - some people joined us just for this part of the day's proceedings.

The "unconference" board with various topics

We gathered round in sharing and debating the latest trending topics, such as GNU Guix.
