What is a semaphore? How do they work? (Example in C) // Semaphores cause a lot of confusion for students, largely because they are super flexible and a little weird. In this video, I try to provide some insight into how they work, and an example of where you could use semaphores to coordinate different processes.

Welcome! I post videos that help you learn to program and become a more confident software developer. I cover beginner-to-advanced systems topics ranging from network programming, threads, processes, operating systems, embedded systems and others. My goal is to help you get under-the-hood and better understand how computers work and how you can use them to become stronger students and more capable professional developers.
About me: I'm a computer scientist, electrical engineer, researcher, and teacher. I specialize in embedded systems, mobile computing, sensor networks, and the Internet of Things. I teach systems and networking courses at Clemson University, where I also lead the PERSIST research lab.
