I feel stupid saying this over and over each time one of his guides pop up, and I know he lurks here, but thanks Beej.

All of his material is absolutely top notch. His guide to network programming was instrumental to both my understanding and career. It often feels like thanks isn't quite enough.

I was lucky to work with him for a while. He’s a great guy IRL too.

Yea agree, free educational content is worth so much. Especially in a world where everyone wants to make a quick coin by selling courses or whatever. Would never have looked into C if it wasn't for beejs guide, as that other book that's often recommended is as dry as math books...
