DORS/CLUC 2023 is ready – find out what’s going to happen!

We are proud to announce we are ready for this year’s DORS/CLUC conference. Read on to find out what it is!

For the 28th time, the conference will take place at the Faculty of Electrical Engineering and Computing, University of Zagreb, and will bring together developers, system administrators, hackers and businesses.

If you are not sure whether DORS/CLUC is right for you, let us make your mind by showing this year’s rich conference program, and the amazing workshops you can attend!

Remember, if you want to attend, you have to register for the workshops!


We especially highlight this year’s keynote: Marko Budiselić, co-founder and CTO of the Croatian open source companies Memgraph and Jeffrey A. McGuire, Open Strategy Partners, Lina Ceballos project manager at Free Software Foundation Europe and Zvonimir Sabljić, the founder of another Croatian open source company – Ptyhagora.

Marko Budiselić, Memgraph

The first keynote conference, Marko Budiselić, is co-founder and CTO Memgrapha. Memgraph is, as the name suggests, a relatively new and fast-growing open source database graph that makes life easier for programmers dealing with storage and graph algorithms. It was developed in modern C++, distributed and optimized for speed and scalability in a graphist context.

Marko will give a lecture on the challenges of running a company, managing and developing open source tools in the business environment, thus describing the path of Memgraph as a company, but also as a technology. Marko relies on technologies such as C++, Python and Rust in his work.

Jeffrey A. McGuire, Open Strategy Partners

Jeffrey A. “jam” McGuire, is a partner of Open Strategy Partners, where he helps organizations grow with the help of open source, business methods and business culture. In his work, he tries to combine the values that come from technology, with the people who should find out about these valuesand technologies. Jam achieves this by lecturing and participating in podcasts, but also helping the creators of the technologies themselves find the right message for their existing and future users.

The conference will give two lectures: keynote on open technologies and open source – an analytical view of success in the last 24 years, and a look into the future – further; and a second lecture on how to understand the essential technological facts of software as a tool or product, and how to apply them to create a communication plan that will increase its acceptance and use.

Jeffrey’s approach to technology and marketing, finding humanity in complex technological solutions, and his dedication to open technologies and opentechnology TV have certainly left their mark on the FOSS community over the past 15 years. Don’t miss his lecture.

Lina Ceballos, Policy Project Manager at the FSFE

Lina advocates for software freedom, making sure that technology doesn’t undermine people’s rights. He has experience monitoring legislative processes in the EU and works with different stakeholders and decision-makers.

The talk will explain how policy decisions and their implementation have a major impact on free software, its ecosystem and its communities. With the help of the framework of our project “Public Money? Public code!”, FSFE advocates laws requiring that publicly funded software developed for the public sector be publicly available under a free software license. In his lecture, he will make a brief overview of previous and current EU policy topics, giving a special focus on the regulations on interoperable Europe, the need for access to the EU to be “Free Software first” and explain the key role that other stakeholders, especially civil society, must play in all this.

Zvonimir Sabljić, initiator of the project and company Pythagora

Zvonimir is an engineer and technological entrepreneur with a master’s degree in informatics. He founded AWW (A Web Whiteboard), which became a major player in the online whiteboard market. Under hisleadership, AWW expanded to 1.5 million monthly active users, with Apple as the largest customer. Zvonimir is always exploring new opportunities to bring top-notch solutions to market, while he is currently focused on introducing the next step in theautomation of software testing through Pythagoras.

At the conference, they will tell what Pythagorais is and how it came about for simple reasons – all software requires testing, and today automated tests are the conditions for creating scalable web applications. Wellfunded technical teams spend 20-30% of their time writing and maintaining automated tests. However, developers just don’t like to spend time writing tests when they can work on exciting new basic features.

Pythagora, a tool aboutcreated code, creates automated integration tests by analyzing server activity without the need to write a single line of program code.

Open 4 business

Open 4 Business is a business networking event, an integral part of the DORS / CLUC conference, and is intended for everyone who is interested in establishing new business contacts, finding new projects and exchanging ideas with other experts.

Ifyou want to announce your participation to other business-oriented visitors and thus allow the organizers to post a link to your company’s website, sign up on the Open 4 Business event page, and in return you can expect networking with companies such as Red Hat, EDB, Nimium, Canonical, Open IT, openSUSE and others.

More information on how to participate and who will appear at Open 4 Business can be found on the conference website:


OpenDataConnected is an initiative of HrOpen members, from which the conference of the same name emerged.

As part of OpenDataConnected, DORS/CLUC will feature representatives of the Dutch Ministry of Health and the Ministry of the Interior, representatives of the Central State Office for the Development of the Digital Society, which will organize a datathon as part of the OpenDataConnected track, and Angela Baker, Data Assurance Program Lead From the Open Data Institute.
