Kennissessie OpenSourceWerken: Hoe werkt dat?
Opensourcewerken is zoveel meer dan alleen code delen. Hoe bouw en onderhoud je een community rondom een open source product? Hoe zorg je ervoor dat de community echt bijdraagt aan innovatie en doorontwikkeling?
Tijdens de volgende kennisessie neemt Esmeralda Tijhoff (DICTU Web&App) je mee in haar ervaring met de community rondom het generieke Drupal Intranet. Dit intranet is open source ontwikkeld en wordt binnen de rijksoverheid breed ingezet. Zij deelt best practices en uitdagingen bij het opzetten van een duurzame community en laat zien hoe community-inbreng verder gaat dan code alleen.
Daarnaast zoomen we in op de bredere Drupal-community:
🔹 Welke events activeren de community?
🔹 Hoe houden we contact en stimuleren we samenwerking?
🔹 Wat is de impact van community-inbreng, zowel technisch als niet-technisch?
🔹 Hoe verschilt de Nederlandse Drupal-community van de internationale, en hoe werken we samen?
Waar? Dev.loer, de samenwerkruimte van Developer Overheid en Common Ground op Utrecht CS. Adres: Catharijnesingel 55 te Utrecht. Hoe je hier precies komt ontvang je na aanmelding voor het evenement.
Waarom? Op deze manier zetten we verschillende disciplines rondom het thema opensourcewerken in de spotlight, want opensourcewerken is zoveel meer dan het delen van broncode. We kunnen van elkaar leren: opensourcewerken in de praktijk!
Met wie? Projectleiders, inkopers, OSPO's, IT-bedrijven en anderen die werken voor, bij en aan een digitale (semi)overheid. Ook is er altijd iemand van Opensourcewerken, Developer Overheid of Code4NL aanwezig. Kom met je team of haak individueel aan.

"But my code ain’t pink: Navigating the IT Landscape as a Woman"
Imagine walking into a room full of people where none of the attendees look like you. It makes you feel like you don’t fit in, like you don’t belong. It makes others look at you like you don’t belong. It’s not because you’re unqualified or unfamiliar, but because of something as fundamental as your gender or color. This is the reality for many women in tech—a field where they make up just 15% of software developers (Stack Overflow, 2023). As a woman navigating this industry, I’ve encountered both blatant barriers and subtle biases. But I’ve also seen how small shifts in mindset and behavior can create significant change.
In this inspiring talk, I’ll share my personal journey as a woman in IT, blending humor, hard truths, and hope. I'll share personal anecdotes—from my transition as a historian to fulltime webdeveloper, my first year at DICTU as a the only female Drupal developer while balancing my role as a mother of two, then three, now four kids, and my professional growth in the Drupal community. Along the way, we’ll tackle stereotypes, explore data-driven insights, and reflect on how male allies can make a meaningful difference. Expect candor, a few surprising anecdotes, and a fresh perspective on why diversity matters—not just for women, but for the entire tech community.

Title: How I escaped poverty using Drupal. The emancipating power of free and accessible Drupal training.
In this personal and uplifting session, Esmeralda Tijhoff shared how she rebuilt her life as a single mother on welfare with no IT background — thanks to the power of open source. Through free online Drupal tutorials and sheer determination, she carved out a new career in tech. Today, she works for the Dutch government and serves on the board of the Dutch Drupal Association.
Esmeralda talked about the realities of poverty, breaking into a male-dominated field, and how access to knowledge can transform lives. Her story is a call to the community: invest in documentation, open education, and each other. Because open source is only truly open when it gives everyone a chance.
