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.

I love how you identify stumbling blocks and quickly go over the basics nobody else bothers with. Wish I had had your videos 20 years ago!

Such a needed video. We need these kind of short and concise videos man

[namewithheld]

Well explained and easily understandable which is rare.

Just started cs50 and could not understand command line arguments, this helped me a lot! Thank you!

[victorcercasin]

Hey brother Sorber! I don't know if you remember me but I served part of my mission in your area towards the end of 2018 and beginning of 2019. You talked to me about the difference in computer engineering and software engineering and convinced me to pursue a degree in software engineering. I happened to stumble on this video as I'm trying to quickly learn C for a project in my computer networks class. I hope all is well!

Hello, I just found you through this video and, from a glance at your channel, I see that you make videos on just what I am passionate about: low-level languages, embedded systems and hardware... well, I *had to* subscribe!! :p haha. Anyway, thank you for sharing your knowledge! Greetings from Argentina.

Wonderful video with a great example to help illustrate its function thanks a ton!

[toddschmieder]

Holy cow! That was awesome! Thank you!

[robertnelson]

Could you go into more detail in another video on the command line? Like how to make a command utility, run multiple programs using the command utility, and to pass args to a second prog?

I actually cant believe id did not use this in my coding classes. ty sm!!

[tomasvalent]

Can I change value of argc or argv? I saw something like that in CodeBlocks, they add some numbers there and argc or argv can write them out. (I use dev cpp)

[bikki]

how can i use argv to trigger different methods e.g. "anapp dostuff" returns "doing stuff"

[Alexis_Lynna]

What text editor are you using ? Also if you run a file with a text document piped in like “ ./a.out < file.txt “ do you have to open the file or can you simply loop through the file and store data as needed ?
