EuRuKo 2024

What is EuRuKo?

EuRuKo (European Ruby Konferenz) is the largest and longest running annual Ruby conference in Europe, since 2003, that brings you all the good news about Ruby and its friends. Every year it takes place in a different European city, the location being chosen by participants.

Past EuRuKo's

G.O.A.T. EuRuKo 2024

EuRuKo 2024 will be held in Sarajevo, Bosnia and Herzegovina.

The first-ever Ruby conference in Bosnia and Herzegovina will be held in person, both for participants and speakers. We will not plan to provide a stream, but we will record all sessions and publish them at a later date on EuRuKo's official youtube channel.

The pitch we made for 2024 was for a G.O.A.T. EuRuKo, the greatest of all time of course, but also because of the famous goat from Tuzla, BiH. The story behind this has been passed down for generations, if you want to learn more about the goat, click on the button below.
