In this live episode Omar and myself get the ping application working. Not the best written C code, but it works, after I figured out we need to run the application as root.

In this live episode Omar and myself try to write a low-level C app that does a network ping. Omar really wanted the app to be in C, so you get to watch me struggle to remember C syntax and translate bytes, chars, etc.

We do an OK job of explaining networking but a better job of explaining hex and how numbers are represented by bits (base 2) and bit shifting.
