New blog post: Burau and the infinite parking garage.
On a fun open problem in mathematics, easy to explain and implement an algorithm for, deceptively hard to find the solution to.
Best part about https://www.state.gov/biographies/donald-j-trump/ is how the time (but not the date) seems to be changing all the time.
Numerical instability in the simulation?
SciPy 1.6.0 just made it in before the end of 2020!  I'm personally quite happy with how its new matching solver came out. 
I was a bit surprised to see that comma.ai explicitly values programming competition participants in recruiting, but seeing geohot feature on https://adventofcode.com/2020/leaderboard explains a lot.
Back of the envelope: So, according to a more or less randomly picked internet source , 1 mink causes about 10 kg of CO2eq emissions over its lifetime. So, culling 15 million of them will save us about 150000 tons CO2eq per year (not counting production of whatever people will wear instead). Compare that with the Danish target of reducing emissions by 20 million tons CO2 per year by 2030. Did we just get about 1% closer to that target?
