What is FrOSCon?

Free Software and Open Source - these are the topics of FrOSCon (Free and Open Source Software Conference). Every year in August the computer science department of the University of Applied Sciences Bonn-Rhein-Sieg, supported by FrOSCon e.V., will organize an exciting program with talks and workshops for visitors of all ages. The event is topped off with a fair of booths from FLOSS projects and companies. The social event, celebrated at Saturday night, offers the opportunity to exchange opinions with other visitors, speakers or volunteers.

Keynote Announcement


We are excited to announce our first keynote for the 20th FrOSCon presented Daniel Stenberg.

AI slop attacks on the curl project


"In these days of "vibe coding" and chatbots, users ask AIs for help with everything. Asked to find security problems in Open Source projects, AI bots tell users something that sounds right. Reporting these "findings" wastes everyone's time and causes much frustration and fatigue. Daniel shows how this looks, how it creates a DDoS on projects and how totally beyond absurd this is. With examples and insights from the curl project."

Further Details

It’s just one month to go. There’s still a lot to organize and prepare, but the organizing team is hyped.

If anyone would like to help us at the conference, we certainly won’t say no – feel free to reach out!
