Master curl in two hours. A video course by Daniel
Raw
curl-in-two-hours-agenda.md

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.

See blog post for details.
