How to find us

There will be an additional, special-occasion Summer BOB co-located with ICFP 2019. Save the date for Wednesday, August 21 2019, at Scandic Hotel Potsdamer Platz in Berlin.
The Journal of Functional Programming has graciously made freely available a selection of papers relevant for BOB and Racketfest.

What happens when we use what's best for a change?

Are you interested in technologies beyond the mainstream that are a pleasure to use and effective at getting the job done?

BOB is the forum for developers, architects and builders to explore and discover the best tools available today for building software. Our goal is for all participants to leave the conference with new ideas to improve development back at the ranch.

We are committed to diversity: We aim at exploring a wide range of tools in a welcoming and friendly crowd of diverse people. To that end, a number of support options for participants from groups under-represented in tech are available.
