The interdisciplinary research sanctuary SFI @sfiscience.bsky.social is now accepting applications for its Summer 2025 educational programs. I participated in the Undergraduate Complexity Research program a few years ago and it was life-changing. I highly encourage all curious undergrads to apply.

@redblobgames.com Your blog is amazing. Visualizations enhance learning like nothing else, and I love your work on pathfinding and keep revisiting it. I wish for Christmas we could get a blog post on contraction hierarchies and distance oracles!
