Favorite programmer website (non-blog)
I recently stumbled across John Walker's awesome old website. What a gem of personality and interests: https://www.fourmilab.ch/.
What's your favorite website made by a programmer that isn't just a blog? During my undergrad, I frequently used to use his Your Sky app. Was super helpful getting my bearings of the night sky just before my observations. Or to help me see what planets were visible, etc. Happy to see it’s still around.
