Stuck on something technical? Come talk it through.

Maybe you've got a folder of 800 PDFs and no good way in. Maybe a source sent you a database and you don't know where to start. Maybe your scraper broke the night before deadline, or you're staring at an Excel file with merged cells and dreams. Maybe you just want to know if the thing you're trying to do is actually possible, before you sink three more days into it.

Bring it to a one-to-one session with a data engineer. No prep required, just show up with the problem.

Things people often bring:

Messy data that won't behave
Scraping and extraction that's stuck
An investigation idea where you don't know if the data exists
A manual task you suspect could be automated
When to use LLMs, and when not to
Whatever else you'd like to discuss!

We may get in touch before the conference to learn more, so we can hit the ground running.
Please note: you need to book a time slot in advance. You can do it HERE.

Walking tour: Historical Mechelen (sign up here)

Did you know that Mechelen played an important political and economic role in the Burgundian period in the fifteenth century, when the city was under the rule of the Dukes of Burgundy? Many historical buildings testify to this. Hold tight, because it's a long list: St. Rumbold's Cathedral, the former palaces of Austria and Margaret of York, the Palace of the Grand Council, etc., etc. So no dilly-dallying! Follow the guide through sixteenth-century Mechelen. The Historical City Walk now also takes in the newly discovered fourteenth-century wall paintings in St. John's Church. Unmissable!

If you want to participate, please sign up HERE (we have 25 spots in total).

From the Soviet Union to the Moon – using OSINT on Tintin

Friday May 29, 2026 6:15pm - 7:30pm CEST

Z1.15 - Aula Donche

Comic-book hero Tintin is, without a doubt, the most famous Belgian journalist who never lived. In the course of his 24 albums, which brought him from the early Soviet Union to the surface of the Moon, Tintin did preciously little *actual writing*, but there are still one or two lessons journalists can learn reading the adventures. ‘

Your hosts for this session have set a "trail" through the Tintin stories, and the legacy of Belgium's most famous boy adventurer. Come and compete in a light-hearted quiz which we hope will help you to fall in love with Herge's creation all over again - this time as a datajournalist!

OSINT challenge 2.0

Friday May 29, 2026 6:15pm - 7:30pm CEST

Z0.10

Back by popular demand – and this time the hunt is designed by the people who beat you the last two years: the Scandinavian team. This isn’t a workshop. It’s a chase. No panels. No slides. Just clues, dead ends, and the creeping suspicion that someone else is faster than you. Follow the trail, outsmart the others, and prove your OSINT instincts still work outside your browser.
