As a self-proclaimed nerd when it comes to firewalls, Linux, BSD, TCP/IP—and pretty much anything that contains at least one ESP32—he explains complex technical topics in an easy-to-understand, practical way and spices up his explanations with (sometimes bad ;)) humor.

Biography

Stéphanie Obertin was born on 13 May 1974 in Luxembourg.

Education and qualifications

After completing her secondary school studies in mathematics at the Lycée Michel Rodange, Stéphanie Obertin went on to study general medicine at the Université Louis Pasteur in Strasbourg and then at the Université Henri Poincaré in Nancy. In 2006, she obtained her doctorate in medicine, with a qualification in general medicine.

Governmental posts

Following the legislative elections of 8 October 2023, Stéphanie Obertin was appointed Minister for Digitalisation and Minister for Research and Higher Education on 17 November 2023 in the coalition government between the Christian Social People's Party (CSV) and the Democratic Party (DP).

Professional activities

From 2007 until she joined the government, Stéphanie Obertin worked with four medical colleagues in their general practice in Luxembourg-Bonnevoie. Over the years, Stéphanie Obertin also engaged in a number of complementary activities related to her profession. She worked as a doctor undergoing specialisation in the oncohaematology department at the Centre Hospitalier de Luxembourg (CHL), as a cooperating doctor in the CHL's emergency department and as an accredited general practitioner at the CIPA Gréngewald institution and the Hospices Civils de Pfaffenthal.

Her relentless curiosity and constant desire to broaden her skills led her to take part in multidisciplinary teaching in palliative care, geriatric care and diabetology. She also holds an inter-university diploma in Sports Medicine and Traumatology, as well as a university diploma in the theoretical bases and practical methods of antibiotic therapy in hospitals. Finally, in 2022 she took a course in the diagnosis of skin tumours using optical and digital dermoscopy.

Nathan Coyle

Nathan Coyle is a British PeaceTech and digital innovation specialist based in Austria. He is an Expert Advisor for PeaceTech at the AIT Austrian Institute of Technology and Founder and Principal of the PeaceTech Alliance, an Austrian collaborative bringing together universities, peacebuilding organisations, technology institutions and international partners to develop responsible, human-centred approaches to technology for peace.

His work sits at the intersection of peacebuilding, technology governance, community development, data and artificial intelligence, with a particular focus on ensuring that technology is shaped by the realities of peacebuilders and affected communities. His research covers areas including peacebuilder-centric design, community development as a design metric, data sovereignty and data colonialism, responsible AI, Do No Harm approaches to data, AI infrastructure inequalities, misinformation and trust, and technology diplomacy.

Coyle regularly contributes to international policy and diplomatic discussions on emerging technology and peace. His work has included engagement with the United Nations, OSCE and European Union, including speaking at UN events in Geneva and Vienna, contributing to discussions on emerging technologies, peace and human security, engaging with diplomatic and government delegations through the OSCE community in Vienna, and contributing to European discussions on future peace and conflict research. He also represents and communicates emerging Austrian thinking on PeaceTech internationally, helping connect research, peacebuilding practice and diplomacy.

He has advised governments and public institutions across Europe, Africa, Latin America and North America and is the author of Open Data for Everybody, published by Routledge in 2024. His recent academic and policy work examines the gap between PeaceTech design and practitioner realities, community-centred approaches to AI and PeaceTech in Africa, and global inequalities in AI compute, training data and exposure to armed conflict.

His wider career spans community development, public engagement, policy, research and digital transformation. His writing has appeared in The Guardian, Vice, HuffPost and the New Statesman, he is a TEDx speaker, and in 2024 he was named Thought Leader of the Year at the UK Innovation Awards.

Across his work, a consistent question is who technology is designed for, who has the power to shape it, and how communities can have greater influence over the technologies and data that affect them.

Paul Brown

In the beginning... There was teaching English.

But I began writing professionally for the countercultural Spanish tech magazine @rroba in the 90s, and then went on to be the editor/layout monkey/translator/jack-of-all-trades of the Spanish edition of "Linux Magazine – Chronicle of the Revolution".

When that closed, I also quit teaching completely and became editor-in-chief of Linux Magazine — the German one this time, but again in Spanish. I founded a publishing house with German partners in 2004. We published several tech magazines for a decade, covering free software, Linux, open hardware, and mobile technologies. I wrote scathing editorials criticising big tech, public administrations, proprietary vendors, opportunistic politicians, and everything in between. I did layout, marketed the mag to readers and advertisers, unloaded trucks full with pallets of copies, built an online subscription portal, and learned everything about the publishing business I could, just in case it would come in handy.

When the magazine market went belly up in the late 2000s and early 2010s, we held on until 2014 and then called it quits, and I recycled myself into a "communications expert" because, why not?

I started working as a marketing consultant for KDE e.V. in 2017. I work with the members of the Promo team, setting goals, managing campaigns and analysing results. I also help KDE projects optimise their communication strategies, and I copywrite and proofread their websites and blog posts.

I also run most of KDE's fundraising efforts, and consult for GNOME on the stuff I have become experienced with.

Am I expert? I guess so. I think I can answer a lot of questions of what's going on in the open source market, and can figure out what will work in a campaign, and see opportunities where they are not obvious. Either way, I'll let you be the judge of that.

Lukasz Gornicki has worked in open source since 2014 and full-time since 2020. At the AsyncAPI Initiative he is a maintainer, a member of the Technical Steering Committee, and a former Executive Director, which means he has spent years on the unglamorous side of open governance: how decisions get made, who gets to make them, and what happens when a maintainer walks away.

He also works with Open Source Europe on fiscal hosting for open source projects, which is the other end of the same problem: getting money to people who are not companies.

Earlier he drove open source development inside a corporate environment, working alongside internal OSPOs, and has spent a lot of time explaining to organisations why funding the software they depend on is not charity.
