We just passed 2000 days since the start of the SerenityOS project, and I just love looking at these gource visualizations!

Soundtrack is @KatalinKult's "Ghost Whiskers": https://www.youtube.com/watch?v=Bg4vvcQispc

I was invited by professor Pavel Panchekha at the University of Utah to speak to his CS 4560 (Web Browser Internals) students about Ladybird, and give a demonstration of real-life browser development. We finished up with a Q&A.
