EuRuKo week starts the evening before the conference. Registration opens in the afternoon, followed by a BRUG Meetup — an informal gathering with the local Brno Ruby community. No agenda, no slides. Just a good way to meet people before it all begins.
Matz opens with the keynote, seven talks follow across the day, and the evening ends with the EuRuKo karaoke — the part of the conference people talk about for years.
Two more talks in the morning, city pitches, the closing keynote on parallel programming with Ractors, and the announcement of where EuRuKo goes in 2027. The afternoon is for workshops. The conference wraps at 18:00.
Brno is the vibrant heart of South Moravia and the second-largest city in the Czech Republic — a place where history, creativity, and innovation come together in an inviting mix. Known for its relaxed atmosphere, elegant architecture, and thriving tech and design scene, Brno offers something for everyone.
Wander through its charming streets and hidden courtyards, enjoy a coffee in one of its cozy cafés, or explore the lively cultural spots that make the city feel both sophisticated and approachable. Whether you come to discover its rich history, connect with local talent, or simply enjoy the friendly pace of life, Brno welcomes you with open arms.
