• Dordle, a Wordle variant where you have to guess two words at the same time.
• Intercats, a new seminar from the Topos Institute on “categorical interaction”. I’m scheduled to speak here (in June, so don’t get too excited yet)
• How To Become A Magician. See also Becoming A Magician.
• Postmortem on RatVac. I have the highest level of respect for everyone who made their own vaccine - major props.
• Compositional Thermostatics from Baez, Lynch, and Moeller. I can also recommend Owen’s blog.
