## Summary

Joel Sherrill, project lead for the RTEMS real-time operating system, discusses the history, architecture, and community of the open-source RTOS he has led for 25 years. He explains how RTEMS balances the needs of hobbyists and mission-critical space applications by maintaining deterministic, predictable code while keeping a small footprint. Sherrill details the rigorous selection and management process for Google Summer of Code and ESA Summer of Code interns, highlighting the program's role in sustaining the project's development.
