During the weekend of 19-23 May 2023 I attended the Wikimedia hackathon 2023 in Athens, Greece. The event physically reunited folks interested in the more technological aspects of the Wikimedia movement in person for the first time since 2019. The scope of the hacking projects include (but was not limited to) tools, wikipedia bots, gadgets, server and network infrastructure, data and other technical systems.

My role in the event was two-fold: on one hand I was in the event because of my role as SRE in the Wikimedia Cloud Services team, where we provided very valuable services to the community, and I was expected to support the technical contributors of the movement that were around. Additionally, and because of that same role, I did some hacking myself too, which was specially augmented given I generally collaborate on a daily basis with some community members that were present in the hacking room.

The hackathon had some conference-style track and I ran a session with my coworker Bryan, called Past, Present and Future of Wikimedia Cloud Services (Toolforge and friends) (slides) which was very satisfying to deliver given the friendly space that it was. I attended a bunch of other sessions, and all of them were interesting and well presented. The number of ML themes that were present in the program schedule was exciting. I definitely learned a lot from attending those sessions, from how LLMs work, some fascinating applications for them in the wikimedia space, to what were some industry trends for training and hosting ML models.


Despite the sessions, the main purpose of the hackathon was, well, hacking. While I was in the hacking space for more than 12 hours each day, my ability to get things done was greatly reduced by the constant conversations, help requests, and other social interactions with the folks. Don’t get me wrong, I embraced that reality with joy, because the social bonding aspect of it is perhaps the main reason why we gathered in person instead of virtually.

That being said, this is a rough list of what I did:

The hackathon was also the final days of Technical Engagement as an umbrella group for WMCS and Developer Advocacy teams within the Technology department of the Wikimedia Foundation because of an internal reorg.. We used the chance to reflect on the pleasant time we have had together since 2019 and take a final picture of the few of us that were in person in the event.

Technical Engagement

It wasn’t the first Wikimedia Hackathon for me, and I felt the same as in previous iterations: it was a welcoming space, and I was surrounded by friends and nice human beings. I ended the event with a profound feeling of being privileged, because I was part of the Wikimedia movement, and because I was invited to participate in it.
