Hello all, we would like to thank everyone for their proposals to the developer room. This year we received 18 submissions. However, the time constraint of half a day forced us to limit the number of accepted talks to 8. In case your talk was not accepted, consider joining the devroom as a visitor and please do not hesitate to apply for next year's edition of FOSDEM. To make the selection process fair and unbiased, we asked several people from our community to rank and rate the submitted proposals and hereby thank them for their reviews. The Microkernel and Component-Based OS Devroom will take place on Feb. 1, 2026 at ULB in room K.4.201. The tentative schedule follows (Brussels time / CET): 13:15-13:45 Making the NOVA microhypervisor fit for thousands of devices and interrupts 13:45-14:15 skiftOS: Building a microkernel-based operating system from the ground up 14:15-14:45 Rethinking CPU scheduling for dynamic workloads on Sculpt OS 14:45-15:10 Capability Based Security in Redox 15:10-15:35 Transactions: Making CMRX kernel internals lock-free 15:25-16:00 Practical Persistence on Microkernels (ft. PhantomOS) 16:00-16:30 Updates on GNU/Hurd progress: rump drivers, 64bit, SMP, software bootstrapping ... 16:30-17:00 Microkernels: The last 15 years in retrospective We divided the devroom time into 25 and 30 minutes slots. Please limit your speaking time to 20 and 25 minutes respectively to make room for Q&A and switch over. Also confirm your attendance in pretalx and check if your assigned time slot works. Please notify us ASAP if you have a scheduling conflict. Once your talk shows up on the devroom website at https://fosdem.org/2026/schedule/track/microkernel you are good to go. We are looking forward to see you at FOSDEM, Sebastian & Josef
