A delayed flight becomes time to vibe-code a Harvard course website

The instructor of Harvard’s fall 2025 CS 2840 course says a delayed flight gave them time to vibe-code a website for it. The linked page describes the course as Computational Optimal Transport for Machine Learning and hosts lecture materials. In follow-up posts, the instructor thanked the teaching fellows, guest speakers and students, and said the handmade slides took more time than they’d like to admit.
