Stop Studying for Code Interviews // Just wanted to share some advice about preparing for programming interviews, and whether or not you actually should.
***
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.

How one thread listens to many sockets with select in C. // Ever wondered how to concurrently monitor multiple network connections (sockets) without creating multiple threads? This video shows you how with select(), a universally-available call that so many programmers dont know exists. This is a network-oriented video that shows how select works in a socket server example, written in C, but this technique works with any file descriptor, including files and pipes.
This is also the first of what I expect to be a series of videos on asynchronous I/O and event-driven systems.
