Master curl in two hours. A video course by Daniel

The idea is to make a two and a half hour (give or take) video course explaining and detailing curl, the command line tool. How it works, how to use it, from the basics to some more advanced uses. This will be done by Daniel Stenberg, founder and lead developer of the curl project.

The recording and live-stream is scheduled for August 31, 2023. In the US morning and Euro evening.

Looking forward to it!
As an open-source contributor, I think it would be great to deep dive into curl codebase!

could you update with the scheduled live stream link once you have it?

Sure, that's a fine idea but I think that's left for another video. I think we have enough already to "just" cover the command line use =)

Yes. All my live-streams are always done here: https://www.twitch.tv/curlhacker

I only have used curl for checking for status codes and scrapping data. This course seems like an intro level to how web works and how to navigate it via curl. Curious to see how it comes along!
