Code Smells — issues with the style of your code that makes your code harder to read, understand, and maintain. They are super common, especially in student code. So, this is the first in a series of videos about code smells. Hope it helps you produce better code.

Today's smell: Magic numbers. In short, don't stick numerical constants throughout your code unless it's painfully obvious what they do and your code wouldn't be easier to maintain with a symbolic representation (variable, macro, etc).

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.
