This lecture by John Baez was just one of several really interesting talks:

 
 
In particular Evan Patterson's short introduction to Categorical Logic:

At 17:48 there is a an interesting slide mentioning Bicartesian Closed Categories, which I'd never heard of: A bicartesian closed category is a cartesian closed category with finite coproducts. ... Note that a bicartesian closed category is bicartesian (that is, it is both cartesian and cocartesian), and furthermore it is cartesian closed, but it is usually not cocartesian closed (as the only such category is the trivial terminal category), nor co-(cartesian closed) (i.e., the dual of a cartesian closed category; aka, cocartesian coclosed).

Welsh Republic Podcast Talking With Kars Collective on Armenia Azerbaijan Conflict

Image
  In the last 30 hours, Azerbaijan has blocked the Berdzor Corridor (the only route in and out of Artsakh), established a military police presence, threatened to shoot any flying object leaving the capital Stepanakert, and has now cut the gas supply. This is now a blockage. — Kars Collective (Կարսի Կոլեկտիվ) (@KarsCollective) December 13, 2022 Subscribe to Welsh Republic Podcast .
